The Effect of 1 Running head: GENDER AND TEACHING The Effect of Parents’ Gender Stereotypes on Their Teaching of Novel Object Labels Melissa Frankel Cornell University The Effect of 2 Abstract Extensive research exists on the influence of gender on parental speech and on parental teaching behaviors, but interactions between the two have not been explored. I investigated the impact of gender on parental teaching behaviors by examining the ways in which parental gender, infant gender, the gender of the object, and parents’ implicit beliefs about gender influenced the teaching of novel object labels. The parent-child interactions were coded for gender-dependent behaviors and parental speech patterns. This data was analyzed in conjunction with the results from the Implicit Association Test. Visual representations of the data revealed not statistically significant patterns, possibly because of low power. Mothers displayed more stereotypical gender beliefs than fathers; this trend should be investigated in future studies. The Effect of 3 The Effect of Parent’s Gender Stereotypes on Their Teaching of Novel Object Labels Gender socialization begins at an early age. The rooms of children as young as one month old have been found to contain significantly more toys that are gender stereotyped than those that are gender inappropriate (Rheingold & Cook, 1975). Additionally, baby boys are typically dressed in blue and baby girls are dressed in pink, a trend that began in the 1920s (Paoletti, 1987). However, before 18 months of age, children do not reliably identify gender differences when viewing photographs of males and females (O’Brien & Huston, 1985). Children’s gender stereotypes increase with age and as their ability to identify and label gender differences solidifies (Fagot, Leinbach, & O’Boyle, 1992). Moreover, 2 to 3 year old children whose mothers subscribe to traditional gender views successfully identify gender differences earlier than their peers whose mothers do not hold these traditional beliefs (Fagot et al., 1992). The current study sought to address whether gender differences influence the ways in which parents teach their children novel object labels. Specifically, does the parent’s gender, the parent’s gender stereotypes, the infant’s gender, the gender of the object, or some combination of the four previous factors influence the parent’s teaching behaviors? Adult-infant interactions are shaped by the adult’s gender stereotypes, the child’s gender, and the adult’s gender (Fagot, 1978; Frisch, 1977). Additionally, toys intended for boys are inherently differently than toys intended for girls; these differences influence the ways in which parents and children interact with toys (Blakemore & Centers, 2005; O’Brien & Nagle, 1987). Thus, these four gender dimensions should impact the methods that parents used to teach their infants novel object labels. Gender Influences Parent-Child Interactions Adults react differently to infants and toddlers based on the child’s gender. Fagot (1978) found that mothers and fathers respond more frequently overall to girls than to boys. Although The Effect of 4 children as young as 20 months reliably favor gender appropriate toys, when children play with gender inappropriate toys, their parents often respond negatively by stopping the child’s play or punishing the child, either verbally or physically. This pattern of response is the most consistent when fathers interact with their sons. Additionally, both parents encourage gender stereotyped behaviors such as aggressive, large motor activities for boys and helpful, cooperative, imitative actions for girls. It is not only the biological sex of the infant or toddler that affects the ways in which adults view him or her. Instead, the perceived sex of the infant has a greater influence on adults’ beliefs and actions. Condry and Condry (1976) showed participants a video of a 9 month old infant reacting to various stimuli. Although everyone saw the same video, half of the participants were told that the infant in the video was female; the remaining participants were told that the infant was male. When the infant started crying in response to an aversive stimulus, the participants viewing a “male” infant said that he was angry and the participants viewing a “female” infant reported that she was scared. When this experiment was repeated with expectant parents, fathers-to-be who scored highly on measures of male gender stereotypes classified the infant they believed was male as significantly angrier than the infant that they believed was female (Plant, Hyde, Keltner, & Devine, 2000). When participants were shown a video of two toddlers playing in the snow, clothed in such a way that their features were obscured by their snowsuits, participants rated the toddler’s aggressive behavior as more appropriate when they were told that the toddler was male (Condry & Ross, 1985). Lastly, when an infant who was gender neutral in appearance was presented to another mother for a play session, the mothers provided the “male” infants with higher levels of stimulation than the “female” infants (Smith & Lloyd, 1978). The Effect of 5 This gender stereotyping effect is seen even among non-parents. When non-parents interact with 14 and 15 month old infants, the gender stereotypes to which they subscribe shape their interactions. Non-parents with traditional views of female gender roles show significant differences based on whether they believe they are interacting with a female or male infant (Frisch, 1977). Overall, these adults encourage female infants to play in an interpersonal and nurturing manner, while they encourage male infants to partake in activities with masculine stereotyped toys (Frisch, 1977). Gender also shapes parent-child-toy interactions. The genders of the parent, the infant, and the toy all influence parental speech in unstructured interactions (O’Brien & Nagle, 1987). When playing with gender neutral toys, parents use functional language that facilitates play, but do not encourage children to play imaginatively. When playing with traditionally female toys, parents’ verbalizations are more frequent, longer, and highly varied. When interacting with feminine toys, parents of girls are more likely to use adverbs and adjectives than are parents of boys. Parents ask the most questions in this context, but across all contexts fathers ask the most wh-questions (who, what, where, why, when). Alternatively, when playing with traditionally male toys, parents speak very little. Parents produce more verbs when interacting with female infants than male infants. Additionally, fathers directly reference toys and use pronouns more frequently than mothers. Fathers also use more varied language than mothers when playing with masculine toys. Gender of Objects Toys intended for boys are often very different from those intended for girls. Blakemore and Centers (2005) compiled an extensive list of toys and classified them along a continuum from highly masculine to highly feminine, with gender neutral as the midpoint. Although some The Effect of 6 toys’ ratings have changed over time, toys that primarily cater to girls are generally considered to be the most visually pleasing and are associated largely with girls’ physical appearances. Toys that are seen as primarily for boys are largely associated with aggression or violence. These distinctions are more pronounced among toys that are strongly gender stereotyped compared with those that are moderately gender stereotyped. Additionally, strongly feminine toys are most likely to be associated with nurturance or encouragement of domestic skills, but are least likely to be educational in nature or to encourage cooperation and turn taking (Blakemore & Centers, 2005). Conversely, strongly masculine toys are most competitive, tend to involve some kind of construction or assembly task, and are highly arousing and require parental supervision. Gender neutral toys are frequently associated with creativity and often involve some level of artistic skill. Implicit Beliefs A parent’s beliefs about gender roles may also influence the ways in which he or she interacts with infants; however, people are often unaware of or unwilling to admit to their biases. These implicit beliefs (beliefs outside the realm of conscious control) express a positive or negative disposition toward a person, a group of people, or an object (Greenwald & Krieger, 2006). Dissociations, defined as discrepancies between a person’s explicitly stated beliefs and his or her implicit attitudes, occur frequently (Greenwald & Nosek, 2001). One study that examined explicit versus implicit beliefs from 12 difference experiments found that 42% of participants explicitly expressed neutral beliefs, while only 18% implicitly expressed these neutral beliefs (Greenwald & Krieger, 2006). These percentages are bound to vary based on the participants and the types of attitudes under examination (i.e., race, gender, etc.), but the The Effect of 7 discrepancy is notable. However, dissociations are not inevitable; sometimes explicit and implicit beliefs are very similar (Greenwald, Nosek, & Banaji, 2003). Do Parents’ Beliefs about Gender Influence Teaching Behaviors? The ways in which parents best teach their infants novel object labels is well documented. First, 18 month olds can learn and remember novel object labels when a label is presented concurrently with the novel object (Woodward, Markman, & Fitzsimmons, 1994). Research also shows that infants learn object labels when an adult directs his or her attention (through looking or pointing) to the object while he or she utters the novel label. This phenomenon holds true even when infants are presented with an unlabeled distracter item between hearing the novel label and viewing the novel object (Baldwin, 1993). However, if the adult only points at the novel object and does not label it, the infants are less likely to successfully remember these objects (Baldwin & Markman, 1989). Furthermore, children’s vocabularies are greatly affected by their parents’ teaching behaviors. Some research indicates that the frequency of parent-child conversations influences the size of the child’s vocabulary (Huttenlocher, Haight, Bryk, Seltzer, & Lyons, 1991). However, other research suggests that it is not how frequently a mother talks to her infant, but rather the total number of words, the total number of unique words (words with different stems) and the mean length of her utterances (MLU) that shapes her infant’s vocabulary (Hoff, 2003; Hoff & Naigles, 2002). The more frequently an infant hears a word in isolation, as they do in a novel object-labeling task, the more likely the infant will spontaneously produce this word at a later time (Brent & Siskind, 2001). Parental responsiveness is another factor bearing on an infant’s vocal development. In a longitudinal study, infants with larger vocabularies at 13 months were more likely to have had The Effect of 8 mothers who shared and directed their attention at 9 months (Baumwell, Tamis-LeMonda, & Bornstein, 1997). Another longitudinal study demonstrated that 13 month olds with highly responsive mothers had larger vocabularies at both 13 months and 20 months (Tamis-LeMonda, Bornstein, Baumwell, & Damast, 1996). Current Study The current study examined the ways in which parents teach their children novel names for gender neutral stuffed animals. Extensive research has been conducted about parental teaching behaviors and about the ways in which gender influences parent-child interactions, but previous research efforts have not looked for interactions. I explored the ways in which the parent’s gender and implicit gender beliefs, his or her child’s gender, and the perceived gender of the toy influenced teaching by observing each parent as he or she taught his or her child the name of two novel objects. Each novel object was gender neutral in appearance, but described as either male or female to experimentally manipulate the gender. I hypothesized that these four gender dimensions (parental gender, parental gender stereotypes, infant gender, and object gender) would impact the methods that parents used to teach their infants novel object labels. If my hypothesis was correct, I expected to see significant differences in parents’ speech, parents’ behaviors, infants’ behaviors, and parents’ implicit beliefs as a function of the aforementioned gender variables. Methods Participants Data was reported on 16 infants (eight males and eight females) and 26 parents (10 fathers and 16 mothers) from the greater Ithaca, New York area. An additional two infants (one male and one female) and five parents (three males and two females) were tested. The data from The Effect of 9 these participants could not be included in analyses either because the infant cried the entire trial (one female infant and one mother) or the parents did not speak English in the laboratory (one male infant, one mother, and three fathers). Infants were approximately 18 months old (M = 17 months and 29.44 days, SD = 9.16 days) because infants of this age do not yet reliably demonstrate gender stereotyping or gender identification (O’Brien & Huston, 1985). Both parents were asked to participate to see how parental gender influences teaching. However, both caregivers were not always able to come into the laboratory. Participants were recruited through a database that collects infants’ names and birthdates from birth announcements. Additionally, people often request that their contact information be added to the database. As the infants aged into the study, parents received a letter inviting them to participate. This letter was then followed by a phone call to encourage participation. Apparatus Stimuli. The stuffed animals used in this study were selected based on receiving gender neutral ratings from a sample of undergraduate students at Cornell University. The four most gender neutral stuffed animals were selected from the larger pool and used in the current study (Figure 1). Implicit Association Test. The Implicit Association Test (IAT) was administered to every parent. The IAT measures how strongly a participant associates pairs of concepts (Greenwald & Nosek, 2001). The idea behind the IAT is that a participant’s reaction time will be quicker when concepts are appropriately associated. The following example clarifies how the IAT worked in the present study. Participants classified attributes (“power” and “warmth”) into target categories (“male” and “female) (Lane, Banaji, Nosek, & Greenwald, 2007). Stereotypically, males are thought of The Effect of 10 as powerful and females are considered warm (Rudman, Greenwald, & McGhee, 2001). When concepts were more closely associated, a participant’s reaction time was quickest. Concepts were presented in seven blocks (Table 1). Blocks 1, 2, and 5 were warm-up tasks that presented either target categories or attributes. In blocks 3 and 6, participants practiced associating attributes with a target category. Blocks 4 and 7 tested the associations participants practiced in Blocks 3 and 6. In this case, if a participant classified terms faster when “male” and “power” were presented on one side of the screen and “female” and “warmth” were presented on the other, the participant was said to hold stereotypical gender beliefs. The IAT began by displaying instructions that told the participant what to expect and how to proceed through the task. Similar instructions were displayed between each block. Although the words they were asked to associate varied depending on the block, the task otherwise looked the same throughout the blocks. For example, participants were asked to identify words as meaning male or female in block 1. Thus, male was displayed on the left side of the computer screen and female was displayed on the right side. Participants classified the words that flashed in the middle of the screen by pressing “d” and “k” respectively. Only one category (“male,” “female,” “power,” or “warmth”) appeared on each side of the screen in each of the warm up blocks. In the practice and test association blocks (blocks 3, 6, 4, and 7), one target category (“male” or “female”) and one attribute (“power” or “warmth”) appeared together on each side of the screen. These targets and attributes were paired stereotypically in blocks 3 and 6 and gender atypically in blocks 4 and 7. All blocks asked participants to classify words that meant “male,” “female,” “power,” and “warmth” (Table 2) (Rudman et al., 2001). This measure has high levels of convergent and discriminant validity (Greenwald & Nosek, 2001). The IAT also has high levels of predictive validity in terms of predicting The Effect of 11 behavioral outcomes (Nosek, Greenwald, & Banaji, 2007). Additionally, it is fairly easy to administer because participants can complete this assessment on a computer. Thus, researcher error is virtually eliminated and participants are less likely to try to provide the answers that they believe researchers want to hear (Greenwald & Banaji, 1995). MacArthur-Bates Communicative Development Inventory. Parents were asked to collaboratively complete the “MacArthur-Bates Communicative Development Inventory: Word and Sentences” (MCDI). This is a checklist on which parents report the words and simple word combinations that their children can produce (Fenson et al., 1994). This list was included to indicate whether there were significant relationships between the ways in which a parent teaches his or her child novel object labels and the words his or her child can say. This checklist also ensured that any effect of infant gender was not confounded by infants of one gender having a significantly larger vocabulary than infants of the opposite gender. Demographic Questionnaire. Parents also received a demographic questionnaire (Appendix A). It collected basic background information about both parents and the child. Each parent was asked to complete the questionnaire about him or herself. The first parent filled out the questions about the infant and the second parent was told to contribute if anything was missing. Procedure Norming the Stimuli. Prior to the start of the study, fifty Cornell undergraduate students rated ten stuffed animals to assess whether these animals appeared to have a gender association. The students were able to touch and manipulate each stuffed animal. The students then rated the animals on a Likert scale ranging from 1 (extremely feminine) to 7 (extremely masculine). Four of the stuffed animals received a mean rating of approximately 4 (gender neutral). Importantly, The Effect of 12 these stuffed animals had unimodal distributions of ratings, which demonstrated that they really were gender neutral and not considered extremely masculine as frequently as they were considered extremely feminine. These four animals were then used for the present study. Parent-Infant Interactions in the Laboratory. In the current study, each parent taught his or her child about two of the four novel stuffed animals. The parent was told that one of these animals was female and one was male. Each animal came with a short description, which included the animal’s assigned gender (Appendix B). The parent was told that he or she had five minutes (per stuffed animal) to teach his or her child the animal’s species. The species names (hapse, galve, raf, and posp) were made-up words that are phonologically similar to words in the English language (Fitneva, Christiansen, & Monaghan, in press). While one parent was interacting with his or her child and the stuffed animals, the other sat in the waiting room and completed questionnaires. The gender of the parent that interacted with the child first was counterbalanced across the study, as was which species name and gender were assigned to which stuffed animal. After both parents interacted with their child, a research assistant entertained the child while each parent completed the IAT and finished any incomplete questionnaires. The parents were then debriefed about the purpose of the study. The entire session was videotaped so it could be transcribed and analyzed. From start to finish, each family was in the laboratory for approximately one hour. Coding Every parent’s interactions with his or her child were video recorded and then transcribed and analyzed using Event Coder, a program that allowed a research assistant to press a key on the computer keyboard every time a parent or an infant carried out a behavior of interest The Effect of 13 (Goldstein, 2007). I assigned one key to correlate with each behavior that I needed to analyze. These interactions were first coded to note the amount of time the parent spent holding and looking at the stuffed animal. The amount of time the infant spent holding and looking at the stuffed animal was also noted. The amount of time that parents and infants spent looking at and holding the stuffed animals was measured to represent that amount of time each spent engaged with the stuffed animals. Additionally, parents’ active and passive labels were coded. A passive label was defined as a parent stating, “This is _______ (stuffed animal species).” If the parent incorporated the stuffed animal’s species into a game or activity, this was considered an active label. Each time an infant attempted to say the animal’s species, it was logged. The number of unique words each parent uttered and the parent’s MLU in each trial was recorded. Furthermore, each parent’s implicit attitudes about gender were measured using the IAT to see how these beliefs impacted his or her teaching. Difference scores were calculated from each parent’s IAT output (Table 3) (Lane et al., 2007). Higher difference scores indicated more stereotypical implicit beliefs about gender. This study employed a 2 x 2 x 2 design to examine infant gender (male or female), parent gender (male or female), and the assigned gender of the stuffed animal (male or female). The results of the IAT were analyzed with a regression. Results Selecting the Stimuli (Stuffed Animals) The four stuffed animals that received average ratings of approximately 4 (gender neutral) were used as stimuli. Animal 2 (M = 3.70, SD = 1.27), animal 3 (M = 4.45, SD = 1.75), animal 5 (M = 4.25, SD = 1.68), and animal 6 (M = 4.65, SD = 1.51) were the stimuli for the The Effect of 14 current study (Figure 2). There was no significant difference between the female undergraduates’ ratings and the male undergraduates’ ratings. Parental Speech Measures Mothers introduced more unique words when interacting with their daughters; fathers introduced more unique words when playing with their sons (Figure 3). A 2 (trial) x 2 (infant gender) x 2 (parent gender) mixed analysis of variance (ANOVA) on unique words failed to reveal significant interactions or main effects. However, visual inspection of Figure 3 showed a pattern of parents introducing more unique words when interacting with a child of the same gender. More statistical power is needed to determine if these differences are truly significant. Parents were consistent across trials in the number of unique words that they said. The correlation of unique words in trial one and trial two was significant for mothers, r (15) = .90, p = .000. The correlation of unique words in trial one and trial two was also significant for fathers, r (9) = .87, p = .001. A 2 (trial) x 2 (infant gender) x 2 (parent gender) mixed ANOVA on MLU failed to show significant differences or main effects of parents’ gender or infants’ gender. Nonetheless, visual inspection of Figure 4 revealed a pattern of parents having higher MLUs when interacting with boys than with girls. Again, more statistical power is needed to determine if this pattern represents a significant difference in the population. As with number of unique words, parents were consistent in MLU across trials. The correlation of MLU in trial one and trial two was significant for mothers, r (15) = .81, p = .000, and fathers, r (9) = .80, p = .005. There was no significant difference in the number of passive labels or active labels uttered by mothers or fathers. To eliminate individual variability in each kind of label based on the total number of times the stuffed animal was labeled, the proportion of passive labels to total The Effect of 15 labels was calculated for each parent. The proportion of active labels to total labels was also calculated for each parent. There was a significant effect of parent gender on the proportion of passive labels to total labels, t (9) = -2.422, p = .039, with fathers having a higher ratio of passive labels than mothers. As such, there was also a significant effect of parent gender on the proportion of active labels to total labels, t (9) = 2.422, p = .039, with mothers having a higher ratio of active labels than fathers. IAT D scores were not significantly correlated with the proportion of either kind of label for parents of either gender. Parent-Infant Interactions Visual inspection of Figure 5 demonstrated a pattern that female infants spent more time holding the stuffed animals than male infants. However, a 2 (trial) x 2 (infant gender) x 2 (parent gender) mixed ANOVA on the total time infants spent holding the stuffed animals failed to display any significant differences. Here too, more statistical power is needed. Infants were significantly consistent in the time spent holding the stuffed animals across trials when interacting with mothers, r (15) = .632, p = .009, and fathers, r (9) = .742, p = .014. Another pattern visible in a graph of the data was that female infants looked at the stuffed animals longer than male infants, but only when interacting with their fathers (Figure 6). A 2 (trial) x 2 (infant gender) x 2 (parent gender) mixed ANOVA on the total time infants spent holding the stuffed animals also failed to find significant differences in this data with the limited statistical power available in this study. Visual examination of Figure 7 showed a pattern of parents of both genders spending more time holding the stuffed animals when interacting with male infants than female infants. A 2 (trial) x 2 (infant gender) x 2 (parent gender) mixed ANOVA on the total time parents spent holding the stuffed animals did not reveal significant differences in parents’ holding time. The The Effect of 16 amount of time fathers spent holding the stuffed animals was significantly correlated from trial one to trial two, r (9) = .893, p = .001. The amount of time mothers spent holding the stuffed animals was not significantly correlated between the two trials. A visual representation of the amount of time parents spent looking at the stuffed animals displayed patterns of parents looking for greater lengths of time when interacting with infants of the opposite gender (Figure 8). This pattern was shown not to be significant by a 2 (trial) x 2 (infant gender) x 2 (parent gender) mixed ANOVA on the total amount of time parents spent looking at the stuffed animals. Once again, greater statistical power is necessary to see if these patterns are significant in the greater population. Implicit Association Test The data from the 2 (infant gender) x 2 (parent gender) ANOVA on the scores from the IAT suggested a main effect of gender that approached significance, but was not significant F(1, 8) = 4.41, p = .069. This trend in the D scores suggested that mothers held more stereotypical implicit beliefs about gender than fathers (Figures 9-11). However, it is necessary to test more participants to determine if this effect was representative of significant differences in the population. This ANOVA revealed neither an effect of child gender on IAT D scores or an interaction effect of parent gender and infant gender. Next, I analyzed the impact of the amount of time mothers spent with their infants on mothers’ gender stereotypes. Since it is impossible to accurately measure the exact amount of time mothers spend with their infants, I used the mothers’ primary location of employment as a proxy for the amount of time spent with their infants. Eight mothers’ primary occupations occurred in their homes; eight mothers’ primary occupations occurred outside of their homes. Mothers who worked outside of their homes had marginally significantly more stereotypical The Effect of 17 implicit beliefs about gender than mothers who worked in their homes, t (14) = -2.05, p = .059. Figure 12 depicts a visual representation of the mothers’ D scores as a function of their primary place of employment, illustrating this pattern. There was no significant difference in the proportion of the kind of label mothers used (passive or active) to name the stuffed animal based on their primary place of employment. Discussion The Current Study Interesting patterns emerged that require future investigation. I expected to find significant differences in parental speech patterns and behaviors and infants’ behaviors based on gender. Although I did not find any such differences, it is likely that these were obscured by low statistical power. It is also possible that the glaring differences evident in the literature no longer exist because many of the publications are decades old. Recent research is scarce and focuses on older children than those who participated in the current study. Even though none of the differences were significant, visual representations of the data indicate patterns in parental speech and behaviors and infants’ behaviors that should be investigated further. The two measures of syntactic complexity, number of unique words and MLU, revealed conflicting findings. As judged by MLU, parents had more complex speech when interacting with their sons; as judged by number of unique words, a parent had more complex speech when playing with a child of the same gender. It is surprising that two variables used to measure the same thing, syntactic complexity, would show dissimilar data patterns. The patterns in the behavioral data from the interactions were also surprising. I expected that similar patterns would emerge across looking and holding time because they both measured attention focused toward the stuffed animals. However, this did not seem to be the case. The Effect of 18 Although female infants spent more time holding the stuffed animals, regardless of with which parent they were interacting, they only spent more time looking at the stuffed animals when playing with their fathers. Furthermore, mothers and fathers spent more time holding the stuffed animals when interacting with male infants. This pattern is unsurprising when considering that male infants spent less time holding the stuffed animals than female infants. However, what was surprising was that parents spent more time looking at the stuffed animals when playing with infants of the opposite gender. These patterns, although not significant, suggest that looking and holding time do not necessarily measure the same thing (how engaged parents or infants were with the stuffed animals). The results of the IAT were the most unexpected of all of the patterns that emerged from the data. A trend in the data suggested that mothers held more stereotypical implicit beliefs about gender than fathers. This was surprising because Lytton and Romney’s (1991) review of 172 studies found that fathers treat their children in more gender stereotypical ways than mothers. This meta-analysis covered so many studies that children of all ages, from less than one year old to adulthood, were included. Additionally, the marginally significant finding that mothers who work outside their homes had stronger gender stereotypes than mothers who work inside their homes requires attention in future studies. Previous research has found that mothers who are employed outside of the house have less stereotypical gender beliefs, which conflicts with the current, marginally significant, finding (Hoffman & Kloska, 1995). In the context of the increasingly gender egalitarian 21st century, it is counterintuitive that females subscribe to more stereotypical implicit gender biases than males, especially since the perception of females is most changed by greater gender equality (Diekman & Eagly, 2000). One possible explanation for this trend, which should be explored in future studies, is that The Effect of 19 women’s gender stereotypes are activated by playing with their infants directly before completing the IAT. Participants’ attitudes and stereotypes can be automatically activated when they are primed with a word or experience before the completing a task, but all people are not manipulated by the same primes (Bargh, Chaiken, Raymond, & Hymes, 1996; Smeesters, Yzerbyt, Corneille, & Warlop, 2009). As such, parent-child interactions may not activate fathers’ implicit gender stereotypes in the same manner that these play sessions activate mothers’ stereotypes. There are a few ways in which these beliefs could have been activated in the present study. First, it is possible that situational norms, or behaviors associated with a particular environment, activated mothers’ implicit beliefs. Situational norms are automatically activated when a person actively seeks out the environment and when specific behaviors are strongly associated with the environment (Aarts & Dijksterhuis, 2003). The playroom in which parents interacted with their infants could have activated mothers’ caregiving norms and the implicit beliefs that accompany caregiving. Another possible explanation is that mothers were unconsciously primed to achieve the goal of acting like “good mothers.” When people are primed to perform well, they outperform peers who are not exposed to these primes (Bargh, Gollwitzer, Lee-Chai, Barndollar, & Trotschel, 2001). The knowledge that they were being observed and analyzed could have implicitly encouraged mothers to act more maternally, which impacted their IAT scores. Lastly, it is possible that the act of caregiving, which is a stereotypically female task, primed mothers’ gender stereotypical behaviors. These stereotypical behaviors then triggered the implicit beliefs that were visible in their IAT scores. Bargh, Chen, and Burrow (1996) supported this argument when they discovered that people display social behaviors that are consistent with the stereotypes with which they are primed. The Effect of 20 Although these three explanations are plausible in isolation, I believe that they better explain the trends in mothers’ IAT scores when argued in conjunction with one another. Situational norms could activate mothers’ goal directed behaviors. To achieve their goals and act in an environmentally appropriate manner, mothers must behave in a stereotypically feminine way. More concretely, this argument claims that the presence of the infants and the context of the laboratory combined with mothers’ desires to appear maternal led the mothers to act like caregivers, which primed their gender stereotypical implicit beliefs. The situation was more unusual and so the goal of acting maternally was more pronounced for mothers who work primarily outside of their homes and spend less time with their infants. Thus, their infants served as more salient primes and these mothers displayed the most gender stereotypical implicit beliefs on the IAT. Expanding on the Current Study First and foremost, this study must be repeated with a larger sample size. With more subjects, and an equal number of parents of each gender, initial trends will be further developed. However, the trends that emerged from the existing data are telling. When repeating the current study with a larger sample, additional variables should be coded and their impact should be analyzed. First, the amount of time a parent spends engaged in bouts of joint attention with their infant should be analyzed. Joint attention, a hallmark of parental sensitivity to his or her infant’s needs, is “the ability to coordinate attention toward a social partner and an object of mutual interest” (Bakeman & Adamson, 1984, p. 1278). There is a positive association between joint attention and an infant’s vocabulary size at 21 months (Tomasello, Mannle, & Kruger, 1986). Additionally, when mothers and infants coordinate bouts of joint attention, they vocalize more frequently, they hold longer conversations, and mothers speak in shorter sentences and with The Effect of 21 more comments instead of questions or directives (Tomasello & Farrar, 1986). I was unable to measure joint attention in this study because of filming inexperience; when an 18 month old is running around the laboratory, it is difficult to film in such a way that allows for coding the parent’s and infant’s eye gaze directed at the stuffed animal and at one another. Future research should rectify this recording difficulty and examine if differences in the amount of time spent engaged in joint attention, and whether the parent labels the novel object while in joint attention with his or her infant, are significant. After coding where parents and infants are looking, not just if they are looking at the novel object, it will also be important to note whether parents are following their infant’s line of sight or redirecting where their infant is looking. For infants to successfully learn novel words, parents must be aware of and sensitive to their infant’s needs. Researchers have found that a child better learns a novel object label when his or her parents notice where the infant is looking and label the object in the infant’s line of sight, instead of redirecting the infant’s attention to a different object (Dunham, Dunham, & Curwin, 1993). The acoustic characteristics of parents’ speech should be measured and analyzed. Specifically, pitch contours, or fundamental frequency (F0), should be examined. F0 was not analyzed in the current study because (to my knowledge) there are no studies that document the benefits of exaggerated F0 for 18 month olds’ word learning. However, the preference for the enhanced F0 associated with infant-directed speech is well documented among four month old infants (Fernald & Kuhl, 1987). Additionally, the exaggerated F0 associated with infant-directed speech has been shown to help younger infants segment words, which can assist them in incorporating these words into their lexicons (Thiessen, Hill, & Saffran, 2005). Thus, future The Effect of 22 replications of the current study should look at F0 to note possible differences based on parental or infant gender. In addition to increasing the sample size, the gender assigned to the gender neutral stimuli should be more obvious in future studies. The gender assigned to each stimulus was only included in the short description that accompanied each animal. To avoid biasing the parentchild interactions or the IAT, the parent’s attention was not specifically directed to the assigned gender in the description. Many parents either did not notice the gender assignment or chose to ignore it. This is unsurprising in light of research that has observed adults’ and children’s (ages 3-10 years) structured interactions with stuffed animals (Lambdin, Greer, Jibotian, Wood, & Hamilton, 2003). When they were presented with stuffed animals that were previously rated as gender neutral, most adults and children perceived these animals as male. Even when authority figures suggested that these animals were female, children still tended to see them as male. From this data, Lambdin et al. (2003) proposed the animal = male hypothesis, which suggests that people are likely to view gender neutral animals as male. Thus, when replicating the current study, researchers should be less subtle in assigning genders to the stimuli to allow for exploration into the impact of the object’s gender on parental teaching behaviors. This question ultimately could not be examined in the present study because so many of the parents referred to the stuffed animal as “he” or “it,” regardless of the assigned gender. Although the current study examined parents’ and infants’ behavior, there was no measure of whether the infants learned the names assigned to the novel objects. Eighteen month old infants vary greatly in their ability to produce words, so whether the infant can say the stuffed animal’s species name is frequently not indicative of his or her learning. Instead, a simple learning measure should be included in future replications of the current study. After the The Effect of 23 parents have taught all of the novel object labels, both parents and the infant will reenter the playroom, which will contain all of the toys that were present during the teaching trials and two of the novel stuffed animals. The two stuffed animals will be counterbalanced across infants, but each parent will have taught about one stuffed animal and there will always be one male and one female animal. Both parents will then ask the infant to find and bring them the stuffed animals. It will be recorded whether the infant retrieves each stuffed animal and this will be used as a measure of infants’ learning of the novel object labels. Furthermore, it would be interesting to see if the infants who better learn the novel object labels elicited more frequently labeling of the object throughout the trial by gesturing toward the animal or presenting their parent with the animal. A future study should further investigate the trend of mothers displaying more stereotypical implicit beliefs about gender than fathers. A larger sample size will most likely produce more significant differences. Additionally, if interacting with their infants activates mothers’ implicit gender stereotypes, research needs to examine why mothers who worked outside of the home had stronger biases activated than mothers who worked in their homes. Empirical support is necessary to determine whether my aforementioned suspicion is correct and infants act as more salient primes when mothers spend less time with them. It should be investigated whether infants only activate mothers’ gender stereotypes or whether this phenomenon also applies to female non-parents. Lastly, research should also examine whether these differences disappear when mothers are not in an infant laboratory and have not interacted with their infants for a few hours. This phenomenon could be explored by asking mothers to complete the IAT outside of the laboratory after running errands (or some other solo activity) for a couple of hours. After the differences in implicit gender stereotypes have been clarified, The Effect of 24 relationships between implicit gender beliefs, place of employment, and mothers’ behaviors or speech patterns should be further developed. In attempting to answer these pending questions, researchers must bear in mind that repeated administration of the IAT to the same person is correlated with more modest D scores in successive trials (Greenwald et al., 2003). As such, conducting a study that compares differences in women’s gender stereotypes with and without the presence of an infant to prime their implicit beliefs must work around this challenge. One possible way to bypass this hurdle is to employ a between-subjects design that controls for mothers’ primary place of employment or female nonparents’ previous experience with infants. This design cannot reveal the ways in which interacting with an infant influences each woman’s implicit beliefs about gender, but a withinsubjects design in which females complete an IAT before and after interacting with their infants can. The less exaggerated scores associated with repeating the IAT could be avoided if participants do not repeat the same IAT, but instead complete two different IATs with two different sets of attributes that both measure gender stereotypes. In addition to the IAT completed in the current study, participants could classify words associated with math, a stereotypically masculine subject, and arts, a stereotypically feminine subject, into the target categories of “male” and “female” (Greenwald & Nosek, 2001). The current study assumed that parents’ teaching behaviors are influenced by many factors. Specifically, it looked to see the impact of the parent’s gender, the infant’s gender, the parent’s implicit beliefs about gender, and the gender of the object on parental teaching behaviors. Ultimately, the study assumed that it was important to know what influences parents because parents influence their infants. However, if future studies further develop the nearly significant differences in parents’ implicit beliefs, and demonstrate that infants are serving to The Effect of 25 activate these beliefs, it could turn out that infants, as well as parents, drive parent-infant interactions.
