The review focuses on several widely recognized dimensions of children’s social–emotional development: self-regulation, social competence, social cognition, and problem behaviors. We begin by presenting a theoretical perspective that frames our understanding of the interplay between relational and contextual factors that contribute to the social–emotional well-being of DLLs. A targeted search of the literature identified 14 peer-reviewed studies published from 2000 to 2011 that examined social–emotional outcomes for young DLLs in family, school, and peer contexts. Results suggest that DLLs have at least equal (if not better) social–emotional outcomes compared to native English speakers. There is also some evidence that the use of the home language in early childhood classrooms can be a positive, moderating factor for DLLs’ social–emotional development. Contextual and individual characteristics are highly correlated with DLL status, making it difficult to develop clear conclusions about the unique influence of DLL status on social–emotional outcomes. We conclude by identifying avenues for future inquiry. © 2014 Elsevier Inc. All rights reserved. Contents 1. 2. 3. 4.

Being able to regulate one’s own emotional states and recognize and respond to others’ emotions are necessary skills for functioning successfully in social situations (Gross, 2002; Saarni, 1997). Similarly, being able to initiate social interactions, reciprocate appropriately to social gestures made by others, share with others, resolve conflicts, and take turns are important components of social–emotional competency (Denham, 1998; Hubbard & Coie, 1994). There are also important linkages between early social–emotional development and cognitive achievement (Arnold, Kupersmidt, Voegler-Lee, & Marshall, 2012; Raver & Knitzer, 2002). The early childhood years provide the foundation for the development of social–emotional competencies. The relationships that develop between parents and children, as well as non-parental caregivers and peers, set the stage for later patterns of social interactions. Understanding the social–emotional development of dual language learners (DLLs) is important because it is occurring within the unique context of acquiring multiple languages. By definition, a dual language learner is someone who is acquiring two or more languages simultaneously, and learning a second language while continuing to develop his or her first language (U. S. Department of Health and Human Services, 2008). Most learning, both social and cognitive, takes place through interactions with others within specific cultural contexts, and language is the principle medium for these social interactions (Eisenberg, 1999; Rogoff, 1990; Vygotsky, 1978). Acquiring language is an act of “becoming a person” and a member of a particular society, as language conveys important cultural norms (Nelson, 2003; Shatz, 1994). Thus, a child who is learning two languages may need to negotiate between two competing sets of cultural expectations that have distinctive goals for behavior relevant to social–emotional development. Although acquiring more than one language at the same time presents challenges to socialization and acculturation (especially when a child’s home language has a minority status within a society which does not have bilingualism as a goal), developing two or more languages also affords opportunities for the development of bi- or multi-culturalism, such as the ability to communicate feelings in different, culturally-appropriate ways (Cervantes, 2002). In addition, there is some research to suggest that bilingual children demonstrate a number of cognitive advantages that are related to their need to understand social and contextual cues in order to determine which language to use in any particular situation (Cheung, Mak, Luo, & Xiao, 2010; Goetz, 2003). Studies have shown that when bilingual children are compared to monolingual children they demonstrate greater inhibitory control (Bialystok & Martin, 2004; Kovacs & Mehler, 2009), better metalinguistic understanding (Bialystok & Barac, 2012; Galambos & Goldin-Meadow, 1990; Ricciardelli, 1992) and perform better in perspective taking tasks (Greenberg, Bellana, & Bialystok, 2012). It is postulated that the executive control system, associated with such behaviors as planning, initiation of activity, mental flexibility and self-monitoring, is the cognitive mechanism that influences linguistic processing in bilingual children (Bialystok, 2011). There is a growing body of literature that shows that bilingual children outperform their monolingual peers on a variety of executive function tasks (Bialystok, Barac, Blaye, & Poulin-Dubois, 2010; Bialystok & Martin, 2004; Carlson & Meltzoff, 2008; Yang, Yang, & Lust, 2011). In comparison, the social and emotional development of bilingual children has been a focus of scientific inquiry to a lesser degree (Halle et al., 2011). The purpose of this current investigation is to determine the extent to which recent scholarly literature provides information about DLLs’ social–emotional development in early childhood, from birth to age five, and the extent to which this information helps us understand DLLs’ developmental trajectories within the social–emotional domain in the early years of life. We begin with a discussion of theoretical perspectives that are useful in understanding the interplay among cultural, relational, and contextual factors that contribute to the social–emotional well-being of DLLs. Although empirical evidence for understanding the connection of these relational and contextual factors to social–emotional development is limited, for DLL populations, these factors underpin cultural distinctions that are especially salient in comprehending early social–emotional development in bicultural environments. We then provide a brief overview of several important dimensions of social–emotional development: self-regulation, social competence, social cognition, and problem behaviors. These dimensions have been widely recognized as key elements of children’s social–emotional functioning and have figured prominently within conceptual models of social–emotional development (National Research Council, 2008; Raver, 2008). We follow this overview with a summary of the methodology we used for conducting a targeted literature review to examine evidence for the patterns of social–emotional development of DLLs in early childhood. Findings from the literature review are presented and discussed, and implications for future research are considered. 1. Theoretical perspectives for understanding social emotional development in young DLL children As culture plays an important role in both social and cognitive development (Rogoff, 2003; Saarni, Campos, Campos, 736 T.G. Halle et al. / Early Childhood Research Quarterly 29 (2014) 734–749 & Witherington, 2006; Wierzbicka, 1992), and language and culture are interconnected (Ochs, 1986; Schieffelin & Ochs, 1986; Tomasello, 2006), it is logical to draw from theories that discuss the relationship between culture and development to provide a theoretical perspective for understanding DLLs’ social–emotional development. Both bioecological theory (Bronfenbrenner & Morris, 2006) and sociocultural perspectives (Rogoff, 2003; Vygotsky, 1978) provide guidance about how culture operates to influence child outcomes both directly – by the internalization of concepts and their meaning through social interactions with more knowledgeable individuals and indirectly – through the organization of social settings such as schools and community resources (Chen & Rubin, 2011). Only recently have researchers begun to articulate a conceptual framework for understanding the overall development of young DLLs’ development that in part draws upon these theories. Castro et al. (2012) at the Center for Early Care and Education Research-Dual Language Learners (CECER-DLL) have outlined key elements that are found in the bilingual experience of young children growing up in the U.S. Following a sociocultural and historical perspective of development (Rogoff, 2003; Vygotsky, 1978), this framework is founded on the view that children’s development is the result of bidirectional interactions within various cultural contexts, and posits that the quality of language interactions within those contexts, as well as the amount of exposure to the home language (L1) and the secondary language (L2), constitute unique experiences for the development of DLLs compared to monolinguals. Further, this conceptual framework focuses on identifying the particular characteristics of DLLs’ experiences that emerge from their ethnic and language-minority status, suggesting that young DLLs may possess a greater capacity to adapt to novel and variable social conditions when compared to monolinguals. It should be noted that both ecological and sociocultural perspectives have been previously incorporated within theoretical frameworks for understanding the development of ethnic minority children (García Coll et al., 1996; Ogbu, 1981). Still, the articulation and application of these theoretical perspectives in understanding dual language learners’ development is relatively new. The framework is designed to advance understanding about the processes that influence young DLLs’ development and learning across areas of development (e.g., cognition, language and literacy, social–emotional development) and includes several key components: societal, community, and family contexts; early care and education contexts; and child characteristics. We hypothesize that some of these components may be particularly important in understanding the development of DLLs’ social–emotional functioning. Specifically, we describe how relationships within the family and early care and education contexts, and child and family characteristics, are elements of the framework that are particularly salient in explaining young DLLs’ social–emotional development. 2. Relationships within the family and early care and education contexts With respect to social–emotional functioning, the link between individual development and culture is characterized by numerous and dynamic processes where the nature of social interactions and the quality of social relationships are central to how children learn social behavior (Chen, 2011; Stevenson-Hinde, 2011). In these contextual-developmental models, social development is both bidirectional and transactional and social–emotional development occurs within the context of relationships with parents, nonparental caregivers and teachers, and peers (Chen & Rubin, 2011; Sameroff, 2009). Transactional models of development conceptualize development as occurring through reciprocal interactions between individuals, and also reciprocal interactions between an individual and his or her cultural/environmental context (Bornstein, 2009). The notion of bi-directionality further suggests that each social partner can influence the behaviors and skill development of the other. In keeping with the overall conceptual model of DLLs’ development and the theoretical perspective of transactional development within the social–emotional domain, we would expect that young DLLs’ social–emotional development would be uniquely influenced through transactional interactions with significant social partners (i.e., parents, caregivers, and peers) in their earliest social contexts and settings. Below, we review the importance of early social partners and contexts for the social development of all children, but where possible, we highlight research that shows how the quality of these interpersonal relationships may be distinctive for DLLs’ social–emotional development. 2.1. Relationships with parents As children’s first social partners, parents play a critical role in children’s social–emotional development. Two examples of parents’ influence on children’s social–emotional development include the formation of attachment relationships and the transmission of cultural, linguistic, and social norms through specific parenting practices. 2.1.1. Attachment Children’s ability to form a secure attachment with parents and other caregivers is thought to be foundational to positive social adjustment (Ainsworth, 1979; Bowlby, 1982; Dykas & Cassidy, 2011; Sroufe & Fleeson, 1986). It is within the emerging attachment relationship, forged within the first year of life between the primary caregiver and infant, that communicative competence develops (Klann-Delius & Hofmeister, 1997; Sachs, 2005). Early maternal responsiveness has been found to be related to early comprehension skills (Paavola, Kunnari, & Moilanen, 2005) as well as an infant’s attainment of language milestones (Tamis-LeMonda, Bornstein, & Baumwell, 2001). It is through the relational context of attachment that the infant begins to develop his/her language skills (Belsky & Pasco Fearon, 2002; Bus & IJzendoorn, 1988). Currently, little is known about the early attachment relationships between young DLLs and their parents and how these relationships affect later social–emotional development. A recent study suggests that most mother-infant dyads of Mexican origin participating in the evaluation of Early Head Start have relationships characterized by secure attachment (Howes & Wishard Guerra, 2009). Furthermore, this study found that mothers of Mexican origin who had more social support and more contact with relatives in Mexico were more likely than their peers with less social support to demonstrate secure attachment with their children at 14 months. In a study linking the quality of the attachment relationship to later English and Spanish oral language skills, Oades-Sese and Li (2011) studied 469 low-income Latino preschool children and found that parent–child attachment related to English but not Spanish oral language outcome. In addition, the acculturation level of the parent related to their child’s language outcome. Specifically, as parental acculturation increased, children’s English language development increased. Although it is important to know the factors associated with attachment for DLL children and their parents, to our knowledge, no studies exist that extend the study of early attachment to DLL children’s later social–emotional outcomes. 2.1.2. Parental socialization practices It is primarily through parental socialization practices that children learn about their racial or ethnic backgrounds, with parents tailoring information to their children’s age level (Bornstein, 2009; T.G. Halle et al. / Early Childhood Research Quarterly 29 (2014) 734–749 Hughes et al., 2006). Embedded in language are cultural beliefs and values that connect children to their cultural past through oral traditions, literary forms, music, history, and customs conveyed in the primary language (Padilla, 1999). As children’s own language skills are developing, parents are also conveying information about values and beliefs through language. Language not only conveys information through meaning, it also communicates socio-cultural information through its functional features, such as turn taking, turn length, and lexical variation (Ochs, 1986; Schieffelin & Ochs, 1986). Early interactions with family lay the foundation for children’s acquisition of social norms and practices (Schieffelin & Ochs, 1986). These early interactions influence child behavior and well-being, including the development of self-concept, positive social adjustment, and identity formation (Bialystok, 2001; Espinosa, 2006; Oller & Jarmulowicz, 2007). For young DLLs, understanding and using their primary language may enable them to access important information about their culture, which may, in turn, be linked to their developing sense of self and their social–emotional functioning. Maintaining one’s home language in addition to a second language helps to sustain cultural and familial ties as well as support cultural identity, selfconcept, and metalinguistic abilities (Bialystok, 2001; Espinosa, 2006; Gudykunst & Ting-Toomey, 1990; Oller & Jarmulowicz, 2007; Sanchez & Thorp, 1998). However, dual language learners are at risk of losing their home language, especially once they become more immersed in a new language and culture. Loss of a child’s primary language may hinder communication in the family, thus diminishing trust and understanding and feelings of parental control (Tannenbaum & Berkovich, 2005; Tseng & Fuligni, 2000; Wong Fillmore, 2000). 2.2. Relationships in early care and education contexts According to the attachment perspective, non-parental caregivers can serve a regulatory function with regard to children’s social and emotional development. The quality of caregiver–child relationships can be characterized by the levels of closeness, conflict, and dependency caregivers have with children (Howes, Matheson, & Hamilton, 1994). Studies have found that these attachment-related aspects of relationship quality are associated with children’s emotion regulation, and social and behavioral competence (Denham & Burton, 1996; Howes et al., 1994; Stuhlman & Pianta, 2001). Although some children develop relationships with their teachers that are similar in quality to their parent–child relationships, other children have differentiated internal working models and develop relationships that are distinct in their quality and type of attachment (Davis, 2003). For example, Howes et al. (1994) found that the early teacher–child attachment, not mother–child attachment, significantly predicted children’s social competency with peers. Furthermore, there is some evidence that teacher–child attachment relationships may compensate for insecure mother–child attachment relationships (Mitchell-Copeland, Denham, & DeMulder, 1997). The general research on children’s early relationships with caregivers has implications for the study of DLLs’ social–emotional development. In particular, the concept of differentiated internal working models of attachment (Davis, 2003) may be particularly important for DLLs. Children who are growing up bilingually and biculturally will likely be exposed to different socialization practices as conveyed through both speech and action of socializing agents such as parents, early care providers, and early childhood educators. These children may therefore be better able than monolinguals to differentiate between different socialization practices, and consequently could develop distinct relationships with different attachment figures. Depending on individual differences, some 737 DLL children may be more successful than others in differentiating the socialization cues from parents and caregivers, and responding appropriately within different social contexts. Thus, the study of DLLs’ relationships with both parents and early care and education professionals is an important window into the antecedents of DLLs’ social–emotional development. A recent study found that social relationships between teachers and non-native English-speaking preschoolers were rated by teachers to be closer and less characterized by conflict than relationships between teachers and English-speaking children, suggesting that the quality of social relationships between teachers and young DLLs are generally favorable (Luchtel, Hughes, Luze, Bruna, & Peterson). But the contexts in which these relationships develop do matter. For example, there is some evidence suggesting that the use of the child’s home language in the classroom is associated with a higher level of closeness between teachers and DLLs (Chang et al., 2007). There is an emerging literature on classroom characteristics and teacher practices that may be particularly important in supporting the cognitive and social development of DLLs (Howes, Downer, & Pianta, 2011). The Classroom Assessment Scoring System or CLASS (Pianta, La Paro, & Hamre, 2008) is an observational assessment that focuses on classroom quality by examining teacher–child interactions related to classroom organization, emotional climate and instructional support and has been used in several studies that include DLLs. There are mixed findings regarding the association between teacher–child interactions, as measured by the CLASS, and child outcomes. In one study, Downer et al. (2012) found that the quality of emotional support and classroom organization provided by pre-kindergarten teachers were related to gains in DLLs’ social competence across the year. The quality of classroom organization was also negatively related to DLLs’ problem behaviors. The strength of association between observed quality of teacher–child interactions and child outcomes was equivalent for children who were and were not DLLs. However, other studies have found that when DLLs are the primary focus of research there is no association between the CLASS and child outcomes (Lopez, 2011; L. Lopez, personal communication, April 23, 2013; Lopez, Arango, & Ferron). More work is needed to determine whether the CLASS, and other measures of environmental quality in early care and education setting that do not assess aspects of the environment specifically related to DLLs, are valid tools to use with this population. More recently, assessment tools are being developed that measure aspects of the environment and teaching practices that address unique needs of DLLs. For example, (Solari, Landry, Zucker, & Crawford 2011) have developed the Bilingual Teacher Behavior Rating Scale that assesses supports related specifically to DLLs’ language and literacy development, and other supports (e.g., classroom organization and management and teacher sensitivity) that may relate to children’s social–emotional development. They included items in the measure specifically designed to assess whether teachers are responsive to and provide accommodations for DLLs. The importance of relationships for developing social–emotional competence extends beyond children’s relationships with teachers to include the peer network. Young children who have positive peer relationships characterized by sharing, appropriate communication, play, and acceptance are more likely to be successful at school (Downer & Pianta, 2006; Ladd & Burgess, 1999). Research supports this theory and suggests that classroom interactions with peers during play are associated with children’s self-regulation (Elias & Berk, 2002; Mendez, Fantuzzo, & Cicchetti, 2002). Given this extant literature suggesting the importance of peer relationships for children’s positive development, surprisingly little is known about the quality of peer relationships of DLLs. What little 738 T.G. Halle et al. / Early Childhood Research Quarterly 29 (2014) 734–749 research there is suggests that the quality of peer relationships may be affected by a child’s dual language learner status. For example, some dual language learners enter a non-verbal stage of second language development (Tabors, 2008) and peers may misinterpret their silence as being shy or disengaged with the activities around them (Restrepo, 2008). Peers may also ignore or exclude a dual language learning classmate who does not use normal verbal cues. On the other hand, a recent study indicates that the use of DLL children’s primary language by the teacher in the classroom is associated with the reduced likelihood of being the victim of peer aggression (Chang et al., 2007). For DLL children, peer relationships among children who speak the same language may be a particularly important source of support, especially in classroom contexts where the teacher does not speak the children’s home language. It is important that DLL children engage in positive interactions with their English-speaking peers. Castro (2011) suggests that teachers should promote positive peer relationships between young DLLs and their English-speaking peers with the dual purpose of promoting positive social relationships and providing opportunities for English language exposure. Indeed, at least one study suggests that interaction with English-speaking peers is, in fact, correlated with DLLs’ English proficiency (Barrows Chesterfield, Chetserfield, & Chavez, 1982). Similar to Castro (2011), Garcia (2012) notes that classrooms should be set up to be responsive learning communities that are based on several conceptual dimensions, one of which is a focus on maximizing student interactions across categories of English proficiency, academic performance, and immigration status. 3. Child and family characteristics Young dual language learners are not a monolithic group. Castro et al. (2012) posit that there are important associations between DLL children’s individual and family characteristics and their development. Specifically, they cite embedded factors (e.g., SES, immigration status, racial/ethnic identity), socio-cultural factors (e.g., children’s exposure to their family’s native language), and psychological factors (e.g., personality, motivation) as important predictors of DLLs’ functioning across domains. We discuss a few of these key child characteristics below. 3.1. Socioeconomic status Family socioeconomic status has been found to be an important factor associated with the development of DLLs’ social and emotional functioning (Crosnoe, 2005, 2007; Han, 2010; Han & Huang, 2010). However, because language status, income, and other family risk and protective factors (e.g., parents’ emotional well-being, parents’ literacy) are often highly correlated, it is often difficult to disentangle the influence of these factors on children’s development. For example, McLoyd (1990) suggests that poverty increases parenting stress, which diminishes their ability to provide sensitive caregiving, and consequently leads to children’s impaired social–emotional functioning. However, if parents are able to engage in positive parenting practices despite the risks they face, this can buffer the negative effects of family risk on children’s social–emotional functioning (Gershoff, Aber, Raver, & Lennon, 2007; Vick Whittaker, Jones Harden, See, Meisch, & Westbrook, 2011; Yeung, Linver, & Brooks-Gunn, 2002). The research on DLLs is predominantly based on samples of low-income children and not on an economically diverse sample, thereby making it difficult to generalize results. Furthermore, additional family stressors associated with poverty are often not assessed in studies of DLLs, making it difficult to disentangle the association between DLL status, income, and family risk and protective factors, and DLLs’ social–emotional development. 3.2. Immigrant status Immigrant status is another child characteristic that is important to consider in understanding DLLs’ development across domains. Although dual language learners and children of immigrants are distinct groups, there is overlap in the two populations (Castro, 2009). Some research suggests that children who immigrate may be vulnerable to psychological stressors that result in measurable differences in social–emotional well-being when compared to non-immigrant children (Bashir, 1993). Some research also suggests that even if the immigrant experience is that of the child’s parents and not the child him or herself, it could still have a negative effect on children’s social–emotional development, through parent–child interactions (Weiss, Goebel, Page, Wilson, & Warda, 1999). Undocumented status can be a particular source of distress for parents that can indirectly affect child outcomes, as prolonged fears of deportation and separation from family may negatively affect interactions between parents and their young children (Yoshikawa, 2011; Yoshikawa & Kalil, 2011). However, there is also ample evidence that the majority of immigrant children fall within the normal range on behavioral and psychological assessments (Fuligni, 1998; Weiss et al., 1999). Indeed, research actually suggests that immigrant children have more social–emotional competence and fewer behavior problems compared with non-immigrants (Crosnoe, 2005, 2007; DeFeyter & Winsler, 2009; Harris, 1999). In addition, research has shown that positive psychological outcomes for immigrants are related to strong identification with both immigrants’ ethnic group and the larger society (Phinney, Horenczyk, Liebkind, & Vedder, 2001). Together, these findings suggest that it is important not to study factors influencing DLLs’ development in isolation, but rather to consider the myriad factors and mechanisms that influence their social–emotional development. 3.3. Summary The early years of life are an important time for all children to acquire both cognitive and social–emotional skills that will be the foundation for later development. There is some evidence to suggest that the unique experience of simultaneously acquiring two or more languages during early childhood promotes certain cognitive abilities as well as children’s underlying executive function. In comparison to the cognitive and linguistic domains, we know much less about the benefits or barriers to children’s early social functioning based on the unique experience of being a dual language learner (Halle et al., 2011). Relationships with parents, early childhood caregivers and teachers, and peers are seen as foundational to the establishment of social–emotional well-being for all children, including DLLs. Although the research examining foundational social relationships in relation to DLLs’ social–emotional development is slight at present, extant research suggests that social partners and contexts that are able to support a child’s home language as well as facilitate the acquisition of a second language are critical to supporting not only DLLs’ bilingual fluency but also their social and emotional development (Castro, 2011; Chang et al., 2007; Howes & Wishard Guerra, 2009). Given the multi-cultural and multi-linguistic environments in which young DLLs develop, we would expect that the transactional nature of DLLs’ relationships with parents, caregivers/teachers, and peers could be qualitatively different than that of monolingual children, and would therefore result in distinct patterns of association with DLLs’ social–emotional development. Furthermore, recognizing that DLLs represent a very diverse and pan-ethnic group of individuals, we would expect that child and family characteristics such as immigrant status may moderate the association between DLL status and social–emotional outcomes. T.G. Halle et al. / Early Childhood Research Quarterly 29 (2014) 734–749 The goal of this investigation was to determine the extent to which social–emotional development is examined among DLLs in the recent research literature, and from an examination of that literature, to assess what we currently know about the developmental trajectories of young DLLs’ social and emotional competencies. We explore DLLs’ social–emotional outcomes within their distinct group but also in relation to the social–emotional outcomes of non-DLLs, and through the lens of the major dimensions of social–emotional functioning proposed by developmental theorists and researchers. 4. Key dimensions of social–emotional development There are many important aspects of social–emotional development that have received the attention of developmental scholars. However, prominent researchers in the field of social–emotional development (National Research Council, 2008; Raver, 2008) have highlighted several specific dimensions within their conceptualizations of children’s social–emotional development: self-regulation which includes the ability to focus attention, manage emotions, and control behaviors (Blair & Razza, 2007); social competence which reflects the degree to which children are effective in their social interactions with others (Fabes et al., 2006); social cognition which includes children’s cognitive representations regarding relationships with peers and adults (Raver, 2008); and problem behaviors including maladjustment in the development of self-regulation, social competence, and emotional expression (Campbell, 2006). Below, we briefly outline the research on these dimensions and their relationship to children’s overall development. 4.1. Self-regulation Recently there has been a marked increase in research aimed at defining, measuring, and exploring how self-regulation develops in young children (Eisenhower, Baker, & Blacher, 2007; McClelland et al., 2007; Morrison, Ponitz, & McClelland, 2010; Rimm-Kaufman, Curby, Grimm, Nathanson, & Brock, 2009). Definitions of selfregulation vary, but most agree that it includes the ability to focus attention, to manage emotions, and to control behaviors (Blair & Razza, 2007; Rimm-Kaufman et al., 2009). The early childhood period is marked by the substantial development of these abilities, as children learn to attend to activities, to manage emotions, to comply with adult demands and directives, to control their impulse responses and to delay engagement in specific activities (Campbell, 2006; Kuczynski & Kochanska, 1995). The development of self-regulation skills in early childhood is considered foundational for establishing competencies in both social and cognitive developmental domains in later years (Blair & Raver, 2012; Ursache, Blair, & Raver, 2012). In particular, the ability to regulate emotional expressions in a manner that matches cultural and societal expectations is a prerequisite for developing social competence. Conversely, emotional dysregulation can be an early indicator of subsequent behavior problems (Greenberg, Kusche, & Speltz, 1991; Webster-Stratton & Taylor, 2001). 4.2. Social competence Social competence includes the ability to interact effectively with others, and develop and maintain positive relationships (Fabes et al., 2006). The development of these skills in early childhood has been found to be particularly important as they are associated with later academic achievement and social competence in early elementary school (Raver, Garner, & Smith-Donald, 2007). During the preschool period, children should begin to engage in more complex play with peers (Fabes et al., 2006). Studies suggest that children who demonstrate high levels of interactive peer play 739 receive higher teacher ratings on social skills and are better able to cooperate, to resolve conflicts, and to develop empathy, whereas children who engage in disruptive peer play behaviors are reported to have poor self-control and are not well accepted by their peers (Fantuzzo, Sekino, & Cohen, 2004). Positive teacher–child relationships are also associated with children’s social competence. Studies have consistently shown that children who have more supportive and less conflictual relationships with teachers are more accepted by their peers (Birch & Ladd, 1997; Hughes, Cavell, & Wilson, 2001; Taylor, 1989). Secure teacher–child relationships in early childhood have been found to be positively associated with complex peer play and higher sociometric ratings by unfamiliar peers (Howes et al., 1994). 4.3. Social cognition In addition to social competence, the early childhood period is critical for the development of social cognition, or the ability for a child to understand how he or she relates to others and how to interact in a social situation. In essence, social cognition is the cognitive representation of the child’s social experiences in the world (Moore, 2007). In infants and toddlers, this can be seen through self-recognition, such as in a mirror (Bischof-Kohler, 1991), through imitation of an intended rather than an accidental action (Bellagamba & Tomasello, 1999; Johnson, Booth, & O’Hearn, 2001), and also through mutual play with other children and adults (Asendorf, 2002). Studies have shown that children who master aspects of social cognition such as emotion labeling skills and recognition of social cues are more likely to exhibit pro-social behaviors and less likely to exhibit aggression (Denham, 1986; Meece & Mize, 2010). 4.4. Problem behaviors Problem behaviors in preschool are characterized by extreme variations in the development of self-regulation, social competence, and emotional expression (Campbell, 2006). Behavior problems have been categorized into internalizing and externalizing problems. Internalizing problems are characterized by worry, anxiety, sadness, and social withdrawal (Campbell, 2006). Externalizing problems are characterized by hostile and aggressive physical behavior, impulsivity, and hyperactivity (McMahon, 1994). Both types of behavior problems in young children can lead to later maladjustment (Mesman, Bongers, & Koot, 2001). 4.5. Summary The field of social–emotional development has identified several areas of study, including self-regulation, social competency, social cognition, and problem behaviors. We focus on these key dimensions in our analysis of the literature of DLLs’ social–emotional development because they have been found to be important for child well-being, have figured prominently in the way scholars have organized their understanding of the domains of social–emotional development (National Research Council, 2008; Raver, 2008), and have also been found to be responsive to intervention in early childhood (Bierman et al., 2008). While these social–emotional outcomes are defined and understood as universal, our theoretical perspective of DLLs’ social–emotional development would posit that these social–emotional outcomes may manifest themselves in unique ways for DLLs because of the cultural, linguistic, and contextual factors that affect DLLs’ development as compared to monolingual children (Castro et al., 2012; Chen & Rubin, 2011; García Coll, Akerman, & Cicchetti, 2000). The extent to which these dimensions of social–emotional development are examined within populations of DLLs, and the extent to which this examination 740 T.G. Halle et al. / Early Childhood Research Quarterly 29 (2014) 734–749 illuminates our understanding of DLLs’ development within the social–emotional domain, is a focus of our critical review of the literature. 5. Method developmental outcomes for DLLs within the key social–emotional dimensions outlined above. The main goal was to determine the extent to which social–emotional development is examined within populations of young DLLs, and the extent to which this examination helps us understand DLLs’ developmental trajectories within the social–emotional domain in the early years of life. 5.1. Search terms In order to conduct a targeted review of the social–emotional literature, a list of search terms was developed based on guidance from the Center for Early Care and Education Research, Dual Language Learners (CECER-DLL) Steering Committee, and the authors’ knowledge of prior work on both social–emotional development and DLLs (Center for Early Care & Education Research—Dual Language Learners, 2011). Search terms included words or phrases related to the following categories: dual language learners, bilingual, language minority, socio-emotional development, and early childhood (a full list of search terms is available within the online supplementary materials). The databases used to conduct these searches included Psych Info, ERIC, Google Scholar, EBSCO, and JSTOR. 5.2. Inclusion criteria A set of inclusion criteria was used to determine the relevant literature for the review. Specifically, research studies that were published in U.S., peer-reviewed journals where the publication dates occurred between 2000 and 2011 were included in the review. Additionally, studies needed to include children who were DLLs (i.e., children learning a second language while continuing to acquire their first or home language), either as the main focus of the study or at least as a focus of sub-group analyses. The study’s measurement plan needed to include at least one assessment point occurring prior to age six; both cross-sectional and longitudinal studies were eligible for inclusion. The measurement instruments for social–emotional outcomes needed to be administered either via direct child assessment or standardized ratings completed by observers, parents, or caregivers. In addition, the study had to include a typically developing sample of children (e.g., not a sample with a specific medical condition). Lastly, the study could not represent a single case study. 5.3. Procedure The search terms, alone and in combination, were searched within a set of databases and selected journals, as noted above. This search identified more than 30 research articles and eight conceptual articles/books that met the initial inclusion criteria. The list of articles was then reviewed again with the exclusion criteria in mind (i.e., special populations, case studies); articles that did not fit the inclusion criteria were removed from the list. This resulted in 13 articles. An additional article fitting our inclusion criteria but that was not found in the database search was subsequently provided by the third author for inclusion in the review. Thus, a total of 14 articles remained in the final set of studies that were included in the critical review. A table summarizing pertinent information about each of the articles included in the critical review is available in the online supplement. This summary table highlights research questions and study design elements, as well as study findings relevant to the study of children’s social–emotional development. Note that research design was categorized as either longitudinal (i.e., data were collected at two or more time points for a single sample) or cross-sectional (i.e., data were collected at one time point only for one or more samples). We did not conduct a meta-analysis of the 14 studies in our review. Rather, we examined the studies to identify patterns of 6. Results 6.1. Analysis of methodological characteristics of articles reviewed The 14 articles meeting the inclusion criteria included samples from a variety of dual-language learner populations. The majority of studies (11 out of 14 or 79%) focused on Spanish-speaking DLLs (Cervantes, 2002; Chang et al., 2007; Crosnoe, 2005, 2007; Dawson & Williams, 2008; , Farver, Xu, Eppe, & Lonigan, 2006; Galindo & Fuller, 2010; Han, 2010; Howes et al., 2011; Luchtel et al., 2010; Vaughan van Hecke et al., 2007). One study focused on Cantonese speakers (Cheung et al., 2010), one study focused on children from Asian regions (Han & Huang, 2010), and one study focused on Spanish and Creole speakers (DeFeyter & Winsler, 2009). Three articles compared DLLs from various racial/ethnic backgrounds to monolingual English speakers (Han, 2010; Han & Huang, 2010; Vaughan van Hecke et al., 2007), with one of these using generational immigrant status, along with English proficiency, as a population of interest for studying social–emotional developmental outcomes (Han & Huang, 2010). All but one study (Cheung et al., 2010) was conducted in the United States. The study samples varied, but 10 studies relied on large-scale, multi-state or nationally representative datasets. Of the 14 studies, six used the Early Childhood Longitudinal Study, Kindergarten Class of 1998–99 (ECLS-K) (Crosnoe, 2005, 2007; Dawson & Williams, 2008; Galindo & Fuller, 2010; Han, 2010; Han & Huang, 2010), two studies used data from the National Early Head Start Research and Evaluation Project (Howes et al, 2011; Luchtel et al., 2010), one study used data from the Miami School Readiness Project (DeFeyter & Winsler, 2009), and one study used data from the National Center for Early Development and Learning’s (NCEDL) Multi-state Study of Pre-Kindergarten and the State-Wide Early Education Programs Study (SWEEP) (Chang et al., 2007). The remaining four studies included local samples from the United States and China (Cervantes, 2002; Cheung et al., 2010; Farver et al., 2006; Vaughan van Hecke et al., 2007). All but one of the studies included analyses of preschool-aged children (i.e., four-year-olds or in preschool or pre-kindergarten) or kindergartners at the beginning of the study (Vaughan van Hecke et al., 2007). Five studies had a longitudinal design (Chang et al., 2007; Crosnoe, 2005; Han, 2010; Han & Huang, 2010; Vaughan van Hecke et al., 2007) and nine had a crosssectional design (Cervantes, 2002; Cheung et al., 2010; Crosnoe, 2007; Dawson & Williams, 2008; DeFeyter & Winsler, 2009; Farver et al., 2006; Galindo & Fuller, 2010; Howes et al., 2011; Luchtel et al., 2010). Across the various studies, there were different ways of defining “dual language learner.” As mentioned earlier, our definition of dual language learner is a young child who is learning a second language while he or she is continuing to develop his or her first language (U. S. Department of Health and Human Services, 2008). Of the 14 studies, three used a combination of indicators for defining DLL status (e.g., parent report, teacher report, proficiency data from a standardized measure) (Dawson & Williams, 2008; Han, 2010; Han & Huang, 2010), whereas the remaining 11 used a single indicator (e.g., parent report). Six studies that analyzed data from the ECLS-K used the English Oral Language Development Scale (OLDS), which was derived from the PreLAS 2000 assessment (Duncan & De Avila, 741 T.G. Halle et al. / Early Childhood Research Quarterly 29 (2014) 734–749 Table 1 Summary of studies by construct. Reference Cervantes (2002) Chang et al. (2007) Cheung et al.

(2007) reported studies that used the PreLAS 2000 to screen for English proficiency. Several studies focused on the development of social skills among children of immigrants varying by race/ethnicity and country of origin (Cervantes, 2002; Crosnoe, 2007; DeFeyter & Winsler, 2009). Eight of the 14 studies (57%) compared DLLs to non-DLLs (Crosnoe, 2005, 2007; DeFeyter & Winsler, 2009; Galindo & Fuller, 2010; Han, 2010; Han & Huang, 2010; Luchtel et al., 2010; Vaughan van Hecke et al., 2007). The remaining six studies compared various sub-populations of DLLs (Cervantes, 2002; Chang et al., 2007; Cheung et al., 2010; Dawson & Williams, 2008; Farver et al., 2006; Howes et al, 2011), such as comparing Mexican American and Mexican immigrant DLL groups (Cervantes, 2002). The social–emotional outcome measures used across studies varied. The majority of studies (n = 8 or 57%) relied on teacher report for all of the outcome data (Crosnoe, 2005, 2007; Dawson & Williams, 2008; DeFeyter & Winsler, 2009; Galindo & Fuller, 2010; Han, 2010; Han & Huang, 2010; Luchtel et al., 2010). One study used a combination of teacher and parent report (Farver et al., 2006), and another study relied on a combination of teacher report and observation (Chang et al., 2007). Three additional studies relied exclusively on observation (Cervantes, 2002; Cheung et al., 2010; Howes et al, 2011) and the remaining study collected observation and parent-report outcome data (Vaughan van Hecke et al., 2007). 6.2. Findings across studies This section addresses findings from the published literature regarding the social–emotional development of young DLLs. Findings are summarized below by the key dimensions for social–emotional development: self-regulation, social competence, social cognition, and behavior problems. See also Table 1 for a summary of studies, noting coverage of each construct. 6.2.1. Self-regulation Six of the 14 studies (43%) examined emotion- or behaviorregulation (Chang et al., 2007; DeFeyter & Winsler, 2009; Galindo & Fuller, 2010; Han, 2010; Luchtel et al., 2010; Vaughan van Hecke et al., 2007). Two studies found significant differences between first-generation and second-generation immigrant children on measures of self-control (DeFeyter & Winsler, 2009; Galindo & Fuller, 2010); however one study (using the ECLS-K) found a slight advantage of later-generation Latino children compared to first-generation Latino children (Galindo & Fuller, 2010), while the other study (using a Miami-based sample) found firstgeneration immigrant children scoring higher on measures of self-control and initiative than either second-generation immigrants or non-immigrant children (DeFeyter & Winsler, 2009). X X X X X X X X X One of the rare studies that examined developmental trajectories from early childhood through elementary school suggests that some Spanish-speaking DLLs have higher levels of self-control at kindergarten entry than monolingual peers, and continue to excel at these skills through fifth grade, especially if they become fluent bilinguals. Specifically, Han (2010) noted that fluent bilingual Latino children had higher levels of self-control than native English speakers at kindergarten entry and they also had faster growth in self-control through fifth grade. Non-English dominant bilingual Latino children had faster rates of growth in self-control than White, English monolingual children, surpassing them by spring of first grade and continuing to achieve higher rates of self-control through fifth grade. Conversely, non-English monolingual Latino children (i.e., those who did not achieve bilingual status) had the lowest self-control and interpersonal skills at kindergarten entry and continued to trail monolingual English speakers through fifth grade (Han, 2010). English-dominant bilingual Latino children had similar levels and trajectories of socio-emotional skills as their English-monolingual peers. Other studies also indicate that, among Spanish-speaking DLLs, the development of self-regulation is supported by the use of the children’s L1 in early care and education settings. For example, one study found that the amount of Spanish heard in the pre-kindergarten classroom was associated with Spanish-speaking children’s ability to tolerate frustration and orient to tasks, whereas the amount of English spoken in the classroom had no effect on change in frustration tolerance and task orientation from fall to spring of the year (Chang et al., 2007). 6.2.2. Social competence Eight of the 14 studies (57%) included social competence as an outcome (Chang et al., 2007; Crosnoe, 2005; DeFeyter & Winsler, 2009; Farver et al., 2006; Galindo & Fuller, 2010; Han, 2010; Howes et al, 2011; Luchtel et al., 2010). Results from a study using ECLS-K data suggested that Mexican immigrant children had comparable interpersonal functioning to Whites, Asians, and other Latinos, but they had better interpersonal functioning than Blacks (Crosnoe, 2005). Another study by Galindo and Fuller (2010), also using the ECLS-K dataset, found further variation among Latino subgroups. Namely, Cuban and South American children were found to have higher social competency scores than other Latino groups. Compared to white children, children of Mexican decent received similar social competency scores while children of Puerto Rican decent received lower social competency scores than their white peers (Galindo & Fuller, 2010). Contextual factors in the school environment were found to be related to the social competence of young DLLs in some but not all studies. The use of children’s primary language in the classroom may enhance social competence among DLLs. For example, the use of Spanish by the teacher in pre-kindergarten classrooms 742 T.G. Halle et al. / Early Childhood Research Quarterly 29 (2014) 734–749 was found to be positively associated with teacher-reported frustration tolerance, assertiveness, task orientation, and peer social skills among Spanish-speaking children (Chang et al., 2007). However, Howes et al (2011) found no differences in the quality of children’s peer interactions based on whether Spanish-speaking preschoolers interacted with other Spanish-speaking peers or nonSpanish-speaking peers in Head Start and center-based classrooms. In addition, Han (2010) found that children in elementary schools with high levels of stability (i.e., less teacher and student absenteeism, and lower teacher turnover) had significantly faster growth in self-control and interpersonal skills from kindergarten to fifth grade, as reported by teachers, compared to children in schools with lower levels of stability. 6.2.3. Social cognition Two of the 14 studies addressed social cognition (Cervantes, 2002; Cheung et al., 2010). As noted earlier, language is a principle means by which important social and cultural constructs are introduced to young children. The language used to talk about emotions is one example of the intersection of language socialization and the development of social–emotional understanding in children (Chen, Kennedy, & Zhou, 2012). Cervantes (2002) examined mothers’ and preschool children’s use of emotional talk and emotional explanations among Mexican American and Mexican immigrant mother–child dyads. Differences were found when comparing Mexican American to Mexican immigrant children in that Mexican American girls had more emotion utterances than either Mexican American boys or Mexican immigrant girls and boys. Mexican American children and Mexican immigrant boys had more negative emotion utterances than positive ones whereas Mexican immigrant girls showed no difference between positive and negative utterances. Nevertheless, both Mexican American and Mexican immigrant mothers used emotion explanations regularly with their preschool children (Cervantes, 2002). Similarly, children’s ability to adjust the language they use based on the language spoken by those around them represents another example of social cognition (specifically, sociolinguistic awareness). Cheung et al. (2010) assessed the sociolinguistic awareness of Cantonese-native preschoolers living in Hong Kong who either learned English a few hours a week at school from Cantonese speaking teachers or attended school where most of the curriculum was taught in English and the majority of the staff were English speakers. In this study, each child was told to say hello to an experimenter, who then replied to the child in the language the child had not used (e.g., if the child said hello in English, the experimenter would reply in Cantonese, and vice-versa). Children were given five tries to switch the language they were speaking to the experimenter’s. Results revealed that Cantonese-speaking children taught by teachers who only spoke English had greater sociolinguistic awareness, meaning they switched the language they spoke faster, than children taught by teachers who spoke both English and Cantonese. 6.2.4. Problem behaviors Ten of the 14 studies (71%) included behavior problems as an outcome (Chang et al., 2007; Crosnoe, 2007; Dawson & Williams, 2008; DeFeyter & Winsler, 2009; Farver et al., 2006; Galindo & Fuller, 2010; Han, 2010; Han & Huang, 2010; Luchtel et al., 2010; Vaughan van Hecke et al., 2007). One of the few studies that examined outcomes during infancy and toddlerhood concluded that language use in the home (comparing monolingual English, monolingual Spanish, and various levels of English–Spanish bilingualism) does not play a substantial role in influencing externalizing behaviors at 30 months of age (Vaughan van Hecke et al., 2007). Studies of pre-kindergarten classrooms find some evidence for fewer problem behaviors among Spanish-speaking children, but also suggest that the context of the classroom environment might mitigate these patterns. Specifically, Luchtel et al. (2010) found that prekindergarten teachers reported DLLs displayed less frequent and less severe negative behaviors than their monolingual English peaking peers. But Chang et al. (2007) found that the more English interactions a child experienced in the pre-kindergarten classroom, the higher Spanish-speaking children were rated by their teachers on conduct and learning problems and the lower they were rated on frustration tolerance. In addition, Han found that children in elementary schools with more supportive teaching environments had slower increased rates of behavior problems from kindergarten to fifth grade, as reported by teachers, compared to children in schools with less supportive teaching environments. Studies using the same dataset (the ECLS-K) yielded multiple conclusions about the relationship between DLLs’ English language proficiency and their internalizing and externalizing behaviors. For example, Dawson and Williams (2008) found that Hispanic DLLs with limited English proficiency in kindergarten were more likely to exhibit externalizing behaviors in third grade than Hispanic DLLs with more English proficiency, but concluded that English proficiency among Hispanic DLLs at kindergarten entry did not explain internalizing and externalizing behaviors at the end of third grade. Han (2010) and Han and Huang (2010) found that the level of Hispanic and Asian DLLs’ fluency in English in kindergarten coupled with their use of their home language with parents differentially predicted the growth in their internalizing and externalizing behaviors from kindergarten through fifth grade. For example, Hispanic bilingual children were more likely than White English monolingual children to have slower growth in internalizing and externalizing behaviors from kindergarten to fifth grade and lower levels of problem behaviors in fifth grade (Han, 2010). Across these studies, there was convergence in the finding that DLLs who are the least proficient in English tend to have the worst social–emotional outcomes. For example, Han (2010) found that a group identified as “non-English monolingual” children (i.e., those who were not proficient in English by the end of kindergarten and spoke only a language other than English at home) had the lowest self-control and interpersonal skills and the highest level of internalizing problems by fifth grade as rated by teachers; this finding is similar to the findings reported by Dawson and Williams (2008) for longitudinal analyses of the ECLS-K data through third grade, albeit for externalizing problems. 6.3. Consideration of child and family characteristics Socioeconomic differences often account for much of the statistical differences found between subgroups based on home language, racial/ethnic, and/or immigrant background. Family SES was associated with rates of internalizing behaviors, children’s participation in peer-oriented structured extracurricular activities, participation in child care, and the types of schools children attend (Crosnoe, 2005, 2007; Han, 2010; Han & Huang, 2010). Other family risk and protective factors were not often included in the studies, but one study found that among Latino families, parents’ literacy involvement was positively related to children’s social functioning as reported by teachers, whereas parental stress was negatively related to children’s social–emotional competence (Farver et al., 2006). DLL status and language proficiency explained much less of the variance in children’s outcomes than socioeconomic status. Significant effects based on DLL status were reported in only five of the 14 studies (36%) and tended to be small to moderate in magnitude (see table in the appendix). Of the five studies that reported effect sizes, the highest was around 0.42. Furthermore, significant effects of DLL or immigrant status tended to disappear once other T.G. Halle et al. / Early Childhood Research Quarterly 29 (2014) 734–749 family background characteristics were taken into account (Crosnoe, 2005, 2007). There are some noteworthy findings regarding children’s social–emotional development and immigration status. In the studies reviewed, immigrant children tended to have more social–emotional competencies (initiative and self-control) and fewer behavior problems than non-immigrants (Crosnoe, 2005, 2007; DeFeyter & Winsler, 2009). First-generation immigrants had fewer behavior problems than second-generation immigrants, and both groups had fewer behavior problems than non-immigrant children. First-generation immigrants also did significantly better on interpersonal skills (ES = .38) (DeFeyter & Winsler, 2009). However, as noted above, effects of immigrant status on social–emotional outcomes tended to disappear when controlling for other background characteristics (Crosnoe, 2005, 2007). Although there is a significant overlap in the population of children of immigrants and DLLs, the two populations are not necessarily equivalent. For example, there are children of immigrants whose home language is English and DLLs who are not children of immigrants. Although there are shared contextual environments and shared developmental milestones, it is important to distinguish the population of DLLs from the population of children of immigrants. 7. Discussion Within the last decade, the U.S. has experienced a dramatic shift in its child population. Today one in eight residents of the U. S. are foreign born and according to a recent U.S. Census Bureau report, 28% of children age zero to four live in a household where English is not the primary language (Kominski, Shin, & Marotz, 2008). This demographic reality spotlights the need to understand the particular development of young DLLs so that developmental science is representative and inclusive of this growing population. However, because the majority of young DLLs are ethnic and racial minorities experiencing economic and social hardship, research with this population has tended to conflate socioeconomic and other characteristics, potentially obscuring assets in DLLs development (Cabrera, Beeghly, & Eisenberg, 2012). Until recently, advancement in both theory and research for the DLL population has been constrained. The research literature is replete with studies that have overlooked DLLs by under-sampling (NICHD Study of Early Child Care, 1997), combined DLLs into samples categorized as at-risk or immigrant, or prevented DLLs from full participation in studies due to lack of available assessment instruments (Westat, 2000). Fortunately the tide is turning. The new Early Childhood Longitudinal Study, Birth Cohort (ECLS-B, Nord et al., 2004) is cognizant of the need to appropriately sample and assess DLLs; the Institute for Educational Science (IES) is focused on the development of appropriate assessment tools for DLLs; the National Institute for Child Health and Human Development (NICHD) has funded three preschool intervention programs focused on school readiness for DLLs; and the Office of Planning, Research and Evaluation within the U.S. Department of Health and Human Services, Administration for Child and Families (OPRE/HHS/ACF) has supported the development of the Center for Early Care and Education Research–Dual Language Learners. Taken together, these efforts represent a distillation of decades of discussion about the importance of studying minority youth for their own sake within their particular sociocultural contexts (García Coll et al., 1996; Ogbu, 1981). When DLLs are studied in their own right, the focus has tended to be on the development of their language and cognitive abilities rather than on the development of their social–emotional competencies. The main goal of this critical literature review was to examine and document DLLs’ developmental trajectories within the social–emotional domain in the early years of life. 743 Our review of the literature was focused on the major dimensions of social–emotional development (i.e., self regulation, social competence, social cognition, and problem behaviors) and guided by a theoretical perspective that considers social–emotional development to be a function of dynamic, transactional processes with significant social partners (parents, caregivers/teachers, and peers) that are embedded within and may vary across cultural and linguistic settings (Castro et al., 2012; Chen & Rubin, 2011). Our review of the literature published in peer-reviewed, U.S. journals between 2000 and 2011 revealed that research focused on DLLs’ social–emotional development is sparse; only 14 articles were found that met our inclusion criteria. The limited number of studies underscores the fact that the study of social–emotional development among DLLs is an emerging area of research. Clearly, there is a need for more research on the social–emotional development in this important and burgeoning population. Despite the small corpus of studies, a picture of DLLs’ social–emotional development does begin to emerge. DLLs tend to be judged by teachers and observers as higher in measures of self-control and interpersonal skills, and lower in levels of externalizing and internalizing behaviors and other problem behaviors, compared to English-speaking monolinguals (DeFeyter & Winsler, 2009; Han, 2010; Han & Huang, 2010; Luchtel et al., 2010). However, this positive picture of DLLs’ social–emotional functioning needs to be tempered by findings from other studies which show no differences in social–emotional functioning related to language use in the home (Farver et al., 2006; Vaughan van Hecke et al., 2007). We believe that part of the reason for conflicting findings in the current literature is due to the lack of systematic study of DLLs’ social–emotional development. The literature is further complicated by various operational definitions of DLLs across analytic samples, even if the samples are drawn from the same data source (ECLS-K; Crosnoe, 2005, 2007; Dawson & Williams, 2008; Galindo & Fuller, 2010; Han, 2010; Han & Huang, 2010). Nevertheless, the collective findings indicate that young dual language learners function at least as well as if not better than monolingual English speakers in the social–emotional domain. Only four studies permitted an examination of longitudinal development within the social–emotional domain starting in early childhood (Dawson & Williams, 2008; Han, 2010; Han & Huang, 2010). While Chang et al. (2007) looked at social and cognitive outcomes between fall and spring of the pre-kindergarten year, Dawson and Williams (2008) examined social–emotional development from kindergarten to third grade, and Han (2010) and Han and Huang (2010) examined social–emotional development from kindergarten to fifth grade. As noted above, Dawson and Williams (2008) concluded that limited English proficiency among Hispanic children led to more externalizing behaviors over time, whereas Han (2010) and Han and Huang (2010), using the same data set (the ECLS-K) found positive developmental trajectories for both externalizing and internalizing behaviors among Hispanic and Asian DLLs who had fluency in more than one language compared to monolingual English speakers. One explanation for the disparate findings is the different ways that the researchers operationalized language proficiency: Dawson and Williams (2008) relied solely on the findings from the English language screener within the ECLSK to determine English proficiency whereas Han used the English language screener as well as parental report of home language use to classify levels of bilingualism amongst Hispanic (Han, 2010) and Asian (Han & Huang, 2010) children. Furthermore, Dawson and Williams (2008) did not compare Hispanic children to nonHispanic white children, whereas Han (2010), and Han and Huang (2010), did. Finally, the studies differed in their inclusion of other family- and school-level factors in their analytic models: Dawson and Williams (2008) included four child and family characteristics and no school characteristics in their models, whereas Han (2010) 744 T.G. Halle et al. / Early Childhood Research Quarterly 29 (2014) 734–749 and Han and Huang (2010) included a host of time-variant and time-invariant child and family characteristics as well as 14 school environment variables in their models. Later in this discussion, we propose ways that the field can advance a more intentional and rigorous investigation of DLLs’ social–emotional development starting in early childhood. Several factors within the home and early care and education environments appear to be associated with social–emotional outcomes for DLL children. The mechanisms underlying the association between family processes (e.g., parental stress, family literacy) and DLLs’ social–emotional functioning are not fully understood at this time, with many studies using an over-reliance on demographic variables to understand family influences (Castro, 2011). In an effort to better understand the influence of family processes, Farver et al. (2006) included measures of several family risk and protective factors, and found that maternal stress was a negative predictor of DLLs’ social functioning, but parents’ literacy involvement was a positive predictor of social functioning. In addition, Farver et al. (2006) found parents’ perceptions of children’s literacy interest mediate the relationship between parents’ literacy involvement and DLLs’ social functioning; they also speculate that child temperament may play a role. High levels of school stability and supportive teaching environments in elementary school are associated with better social–emotional outcomes for DLLs (Han, 2010). In addition, the use of the child’s primary language in early care and education settings by the teacher appears to be a significant pathway through which closer relationships with both teachers and peers are forged (Chang et al., 2007). These findings support our theoretical perspective that it is important to consider the context in which development is measured such as the home and school contexts–as well as the social relationships with parents, caregivers and teachers–as important influences on DLLs’ social–emotional development in early childhood. It is important to note that some of the findings regarding moderating factors for DLLs’ social–emotional development are similar to what would be expected for any child (e.g., parental stress negatively affecting children’s social–emotional outcomes; Farver et al., 2006), while others are more unique to the context of DLLs’ social–emotional development (e.g., use of L1 in the classroom; Chang et al., 2007). In the study of DLLs’ social–emotional development, it is critical that we distinguish what is universal to all children from what is specific to the needs of DLL children, either by degree or by uniqueness of the cultural and linguistic context in which DLLs develop. On the other hand, the relatively small number of studies that found significant differences in social–emotional development between DLLs and non-DLLs may suggest that all children’s social–emotional development follows a similar trajectory. For example, the one study we found that investigated social–emotional development in infants and toddlers exposed to varying degrees of English and Spanish concluded that DLL status should not be used as a predictor of outcomes at 30 months because no differences were found by DLL status at 24 months (Vaughan van Hecke et al., 2007). However, it is possible that there are longer-term effects on children’s social–emotional development that would be detected if children’s home language and/or language proficiency status were kept in longitudinal models as a variable of interest. In general, we feel more research is needed before drawing the conclusion that there are few differences in DLLs’ and non-DLLs’ social–emotional trajectories. 7.1. Limitations and future research directions The majority of studies meeting the inclusion criteria addressed the social–emotional development of native Spanish speakers or children from Hispanic/Latino backgrounds (11 out of 14 studies, or 79%). Although native Spanish speakers are the largest proportion of non-English speaking children in the United States, the study of DLLs’ development must encompass all DLLs, or at least explore variations among DLLs as well as potential differences between DLLs and non-DLLs. It is noteworthy that several research studies that did not meet inclusion criteria because they were dissertations or case studies examined the social development of Chinese-speaking DLLs (Chen, 2009), Hebrewspeaking DLLs (Hoffman, 2007), and Korean-speaking DLLs (Ryu, 2004). Future research should attempt to gather data from DLLs who speak languages other than Spanish. While children whose home language is Spanish are the largest proportion of DLLs in the United States, they are not the only group of DLLs of interest. In addition, not all Spanish-speaking DLLs can be assumed to develop similarly within the social–emotional domain (Halle et al., 2011). Studies in other countries suggest that the prestige of the home language may be of importance for social–emotional and other outcomes of bilingual speakers (Genesse, 2008; Kohnert, Yim, Nett, Kan, & Duran, 2005; Wong Fillmore, 2000), and even within the United States, policies and attitudes about language of instruction, or the salience and acceptance of Spanish or other non-English languages, varies by state or local contexts. More research is needed on a broader base of dual language learners that takes into consideration the various cultural, social, geographic, and policy contexts in which DLLs develop to understand the complexities of relationships between DLL status and social–emotional outcomes for young children. There are several additional caveats to keep in mind when considering the findings from this review. Our review indicated, for example, that the study of developmental trajectories among DLLs within the social–emotional domain is limited. We found no studies of DLLs’ social–emotional developmental trajectories from infancy through school entry. Only one study of those reviewed examined developmental trajectories from infancy through preschool (Vaughan van Hecke et al., 2007). We found only three studies that examined social–emotional developmental trajectories over the early elementary years among DLLs (Dawson & Williams, 2008; Han, 2010; Han & Huang, 2010). For the most part, the existing literature focuses on point-in-time development for DLLs. One of the barriers to more research on developmental trajectories is the lack of high-quality longitudinal data sets that include well-defined subgroups of DLLs. Future research should include infant-toddler samples followed longitudinally to examine the long-term effects of early social and linguistic experiences on social–emotional outcomes for DLL children. The Early Childhood Longitudinal Study, Birth Cohort (ECLS-B) is one data set that may permit such analyses over time (Winsler et al., 2014). In addition, six of the 14 studies (43%) relied on data from a single dataset: the ECLS-K (Crosnoe, 2005, 2007; Dawson & Williams, 2008; Galindo & Fuller, 2010; Han, 2010; Han & Huang, 2010). There are limitations to this dataset with regard to the study of DLLs, including discrepancies between parent- and school-report of home language, which was the main indicator of DLL status along with an oral language screening tool to measure adequate English proficiency. Happily, a new Early Childhood Longitudinal Study which began fielding in 2010 and will follow another nationally-representative cohort of kindergartners through fifth grade is poised to provide a new and improved opportunity to track DLLs’ development across multiple developmental domains in the years to come. In addition to the current review being based largely on a small set of studies, a limited set of longitudinal datasets, and a limited range of DLLs (mainly Spanish-speakers), the current T.G. Halle et al. / Early Childhood Research Quarterly 29 (2014) 734–749 research base is hindered by several methodological concerns. This literature review highlighted methodological concerns around measurement, defining DLLs, and confounds in research design. Most studies rely on teacher report of child outcomes; there are few direct assessments or standardized observations available. This reliance on teacher report for child outcome data could be threatened by bias; research suggests that teachers have difficulty accurately reporting on children’s skills and behaviors (Konold & Pianta, 2007; Mashburn & Henry, 2004) and this may be particularly true for children from a different culture or language group. Additionally, we need to account for variability in teacher report within longitudinal datasets by using teachers’ fixed-effects approaches to identify true differences in social–emotional outcomes across groups and across years. Furthermore, measures that were developed based on Western values and assumptions may be in conflict with the value perspectives of DLL populations, thus complicating our understanding of social–emotional development of DLLs. Future studies should use more observational measures or direct assessments of social–emotional competence rather than relying on parent or teacher report of children’s social and emotional status. Specifically, research should employ different methods, such as case studies or ethnographies, to provide more detail and a better understanding of the processes underlying social–emotional development in DLLs. Also, the question of construct equivalency across sociolinguistic groups needs to be addressed. The measures that are used in future studies of young DLLs’ social–emotional competencies should be validated for use with culturally and linguistically diverse samples. It is possible that adaptation of existing measures or the development of new measures will be necessary to obtain psychometrically sound data on DLLs’ social–emotional development. The inconsistency in the definition of DLLs and varying methodology used to determine DLL status across studies is of concern. For example, studies using the ELCS-K dataset come to different conclusions about the relationship between English fluency among DLLs and their internalizing and externalizing problems, in part, based on how samples were defined, what analytic techniques were used, and the amount of data included (Dawson & Williams, 2008; Han, 2010; Han & Huang, 2010). There is also imprecision in the methodology used to determine the language skills of DLLs in the literature. For example, the ECLS-K study used a language screener (an adaptation of the Pre-LAS) as the only indicator of English proficiency; this is problematic because it only provides a threshold for assessing a child in English and does not provide an absolute level of the child’s English language proficiency. Furthermore, there is no assessment of English proficiency after “passing” the language screener in kindergarten or first grade, nor is there measurement of proficiency in the child’s home language. Clearly, the field needs guidance on how to define and measure DLL status. Future studies should also take into consideration proficiency in both the home language and the second language. In particular, it will be important to identify a consistent methodology that can be used uniformly across studies to ascertain children’s home and English language skills, and the child’s level of exposure to both languages. It is hypothesized that “home language loss” could have detrimental effects on social and emotional outcomes for children (Wong Fillmore, 1991; Wong Fillmore, 2000), yet we currently have little empirical evidence among young DLLs that this is indeed the case. Having consistent ways to document exposure to and proficiency in L1 and L2 will assist in this line of inquiry. As noted earlier, DLL status is often confounded with race/ethnicity, immigrant status and years of residence in the United States, as well as with SES; few studies effectively disentangle these factors. Additionally, in some cases, small sample sizes preclude looking at differences among bilingual children or 745 disaggregating DLLs from the full sample. For example, most studies do not examine differences among Latino populations within a single Spanish-speaking sample (Chang et al., 2007; Dawson & Williams, 2008; DeFeyter & Winsler, 2009; Farver et al., 2006; Galindo & Fuller, 2010; Han, 2010; Han & Huang, 2010; Luchtel et al., 2010; Vaughan van Hecke et al., 2007). Galindo and Fuller (2010) did examine variations in social competencies based on country of origin. The variations in social competency among Latino subgroups they found underscores that DLLs are not a monolithic group. However, the findings of the Galindo and Fuller (2010) study also suggest that what might be underlying these differences is really a socioeconomic factor. Future research should try to control for socioeconomic status to isolate the findings associated with country of origin, immigrant status, and language status–separately and in various combinations. In addition, it is often hard to disentangle the measures within the social–emotional domain. Distinct dimensions are often combined in an overall composite that might mask important differences between DLLs and non-DLLs (or among DLL subgroups) on particular aspects of social–emotional development, making it difficult to isolate the effects of DLL status on discrete social–emotional dimensions of interest. For example, the social–emotional dimension of “problem behaviors” might benefit from de-coupling internalizing and externalizing behaviors when analyzing outcomes for DLLs and non-DLLs. In addition, our review revealed very little research specifically on self-regulation or social cognition. More research is needed that allows for examination of specific dimensions of social–emotional development among DLLs, and of developmental trajectories in DLLs’ specific social–emotional competencies over the early childhood years. Finally, it is important to note that although the theoretical framework for understanding young children’s social–emotional development includes a focus on transactional, bi-directional relationships starting in infancy, we did not find any extant studies focused on attachment patterns among young dual language learners and their parents and caregivers, nor the relation of these attachment patterns to subsequent social–emotional development among DLLs. Future research of young DLLs should include the examination of early attachment patterns in relation to the development of specific social–emotional competencies. It is anticipated that young investigators who are beginning to study the development of DLLs across a host of different home and early childhood settings, as witnessed by the many posters and presentations featuring DLLs at Head Start’s 11th National Research Conference in 2012, will add to our knowledge base. As the field matures, we hope that the body of research on DLLs will allow for more generalizable information about the social–emotional development of DLLs. 8. Conclusion The small set of studies that report on DLLs’ social–emotional development identified within this critical review highlight the emerging nature of this scholarly area of inquiry. Results suggest that young DLLs have at least equal (if not better) social–emotional outcomes compared to native English monolingual speakers. This small corpus of studies demands that a very intentional, rigorous scientific inquiry of social–emotional development for DLLs be pursued in future research. As noted in the introduction to this review, early relationships established between parents and infants and caregivers and children, and the ways that language conveys cultural meaning within these relationships, are considered foundational to all social–emotional development. Currently, we know very little about the antecedents of DLLs’ social–emotional development (Callaghan et al., 2011). Research that takes into account the 746 T.G. Halle et al. / Early Childhood Research Quarterly 29 (2014) 734–749 cultural and linguistic contexts in which children develop in the early years will inform the field by modeling how these contexts affect early relationships and social adjustment over time. A first step in this direction would be to establish a dynamic, iterative process between theory building and empirical hypothesis testing. We need to refine the theoretical perspectives that will inform our understanding of the unique factors that influence DLLs’ social–emotional development, while at the same time design empirical studies that will test this refined theoretical perspective with more diverse, longitudinal samples so that a clearer picture of DLLs’ social–emotional development can emerge. This future research should attempt to determine the moderating factors that influence the quality of parent–child, teacher–child, and peer relationships, and the subsequent factors that mediate or moderate the influence of relationships on social–emotional outcomes for DLLs. Such future research, we hope, will inform recommendations for parents, caregivers, and policy-makers regarding how best to support the development of DLLs’ social–emotional outcomes.
