Temperament and the Big Five Running Head: TEMPERAMENT AND THE BIG FIVE A Hierarchical Model of Temperament and the Big Five David E. Evans and Mary K. Rothbart University of Oregon Key words: Big Five, personality, temperament 1 Temperament and the Big Five 2 Abstract Temperament constructs and their relation to measures of the Big Five factors of personality were explored. In Study One, 207 undergraduates completed the Adult Temperament Questionnaire (ATQ). After minor modifications, a hypothesized four-factor model fit the temperament data well. The four general scale scores were highly correlated with four Mini-Marker scales assessing Big Five personality factors. In Study Two, 258 undergraduates completed a revised ATQ, with constructs for affiliativeness and aggressive negative affect added. An alternative five-factor model (FFM) emerged, with factors labeled Cognitive Sensitivity, Effortful Control, Extraversion, Affiliativeness, and Negative Affect. This model converged with the Big Five. In Study Three, the model from Study Two was confirmed in a community sample of 700 participants, and convergence with the Big Five of personality was replicated. Temperament may form the biologically-based core of the Big Five domains. Temperament and the Big Five 3 A Hierarchical Model of Temperament and the Big Five Although theorists differ in how they define temperament, there is general agreement that temperamental processes are rooted in biological systems, and that emotion is basic to temperament (see Goldsmith et al., 1987). Ongoing work in animal neurophysiology, human brain imaging, and molecular genetics has led to psychobiological models of temperamental processes that are becoming increasingly compelling and comprehensive (Cloninger, 1998; Gray, 1990; Panksepp, 1998). Based upon heritability research, animal personality, and stability across development and cultures, McCrae and Costa (McCrae et al., 2000; also see McCrae & Costa, 1996) have recently suggested that each of the Big Five/FFM domains has a temperamental base. To facilitate the development of temperament models and to investigate relations between temperament and personality, it is essential to develop psychometrically sound measures of temperament constructs. The studies included in the current report were motivated by the desire to explore the hierarchical relations among lower level constructs of temperament, as well as the relation of temperament to the lexical Big Five model of personality. One method of developing questionnaire assessments involves a rational approach in which constructs are explicitly defined, and questionnaire items written to fit the definition of the construct to which they belong. Researchers have developed rational constructs they consider to be fundamental to understanding temperament (see Strelau & Zawadzki, 1997). Buss and Plomin (1984; Buss, 1991), for example, developed a temperament model including scales for emotionality (fear and anger), activity level, and sociability. Strelau (Strelau & Zawadzki, 1993) developed a model assessing briskness, perseveration, sensory sensitivity, emotional reactivity, endurance, and activity. Derryberry and Rothbart (1988) developed the Physiological Reactions Questionnaire (PRQ) to explore relations among temperament constructs related to arousal, affect, and attention. Defining temperament as individual differences in reactivity and self- Temperament and the Big Five 4 regulation as reflected in the emotions, activity, and attention (Rothbart & Derryberry, 1981), they emphasized definitional specificity. PRQ scales were operationally defined, and items generated to fit these definitions. Conceptual and empirical analyses were then performed to remove items that were more strongly related to scales other than the scales to which they were assigned. Scales were developed to assess multiple components within the affective, arousal, and attentional domains and factor analysis was performed on data from a sample of undergraduate students. A negative affect factor with loadings from fear, frustration, sadness, and discomfort emerged. In a three-factor solution, scales assessing effortful control over the shifting and focusing of attention loaded negatively on this factor, whereas in a six-factor solution, one factor included loadings from the negative affect scales and another, loadings from attentional or effortful control scales. The first factor for both the three- and six-factor solutions included perceptual sensitivity (a cognitive sensitivity construct) as a core component. Perceptual sensitivity scales were uncorrelated with the scales that included an effortful component. In this study, the possibility of further differentiating individual differences in reactive and effortful aspects of attention was explored. This research has modified and expanded the original PRQ instrument into the Adult Temperament Questionnaire (ATQ) to explore the possibility of higher-level (i.e., broader bandwidth) constructs. Using questionnaire measures to assess children, Rothbart, Ahadi, Hershey, and Fisher (2001) found three broad factors (negative affect, extraversion/surgency, and effortful control) that reflect higher level constructs of this sort. Higher level, and higher-level constructs of reactive and effortful attention were also developed, and we were interested in exploring the earlier findings that effortful attention (i.e., attentional shifting and focusing) and negative affect scales were both separable and related, depending on the number of factors extracted. Finally, Temperament and the Big Five 5 the PRQ had included only one extraversion/surgency-related scale, and we wished to further explore the construct by including theoretically related scales. Three of the four broad constructs broken down into scale-level constructs for Study One were consistent with broad factors found in Rothbart’s (Ahadi, Rothbart, & Ye, 1993; Rothbart et al., 2001) caregiver report Children’s Behavior Questionnaire (CBQ). Preliminary analysis of the Early Childhood Behavior Questionnaire (ECBQ: Putnam, Ellis, & Rothbart, 2001) resulted in a similar factor structure. These factors are labeled surgency/extraversion, negative affect, and effortful control. We included these three general constructs along with cognitive sensitivity in the initial version of the ATQ. Definitions and sample items for the scales included in these studies are given in Appendix A. Descriptions of the four general theoretically and empirically based constructs and their sub-constructs are now presented. Evidence from research on childhood temperament (Putnam et al., 2001), adult temperament (Strelau & Zawadzki, 1997), personality (Eysenck & Eysenck, 1985; Tellegen, 1985), neuroscience (Carver & White, 1994; Davidson, 1993; Depue & Collins, 1999; Derryberry & Tucker, 1992; Gray, 1990), and affective individual differences (Watson & Clark, 1992; Watson & Walker, 1996; Watson, Wiese, Vaidya, & Tellegen, 1999) suggests the existence of at least two high level temperamental motivational-emotional systems. One of these systems is associated with potentially aversive stimuli and negative affect, the other with potentially appetitive stimuli and the experience of positive affect. Our labels for these constructs are negative affectivity and extraversion/surgency, respectively. Most models of temperament and personality include variants of negative affect factors (e.g., negative emotionality, Harkness, Tellegen, & Waller, 1995; Tellegen, 1985; negative affectivity, Ahadi et al., 1993; Rothbart et al., 2001; Watson et al., 1999; neuroticism, Eysenck & Eysenck, 1985; McCrae & John, 1992; and emotional stability, Goldberg, 1993). In Derryberry Temperament and the Big Five 6 and Rothbart’s (1988) PRQ study, the negative affect factor included loadings from scales assessing fear (unpleasant affect associated with anticipation of pain or distress), frustration (unpleasant affect associated with task interruption or the blocking of a desired goal), sadness (unpleasant affect and lowered mood related to disappointment, loss, and exposure to suffering), and discomfort (unpleasant affect resulting from the sensory qualities of stimulation) (Derryberry & Rothbart, 1988). These scales were also included in Rothbart’s (Rothbart et al., 2001) Children’s Behavior Questionnaire (CBQ), and modified versions of these scales were retained for the ATQ. As for neuroticism-negative affectivity constructs, most models include variants of a general extraversion/surgency construct (e.g., positive emotionality, Harkness et al., 1995; Tellegen, 1985; positive affect, Watson et al., 1999; extraversion, Eysenck & Eysenck, 1985; McCrae & John, 1992; extraversion/surgency, Goldberg, 1993). In the CBQ caregiver report measure, a surgency/extraversion factor has also consistently emerged (e.g., Ahadi et al., 1993). This factor includes loadings from activity level (vigor and tempo of motor activity), high intensity pleasure (enjoyment related to high levels of novelty and intensity), impulsivity (speed of response initiation), and shyness (negative loading; unpleasant affect and/or behavioral inhibition in novel and social situations), as core constructs. Sub-constructs for extraversion/surgency in the ATQ included in Study One were high intensity pleasure, activity level, sociability, and positive affect. The original PRQ study included only one scale with surgency/extraversion-related content (high intensity pleasure). The PRQ high intensity pleasure scale was to a large extent a sensation-seeking construct, including items related to affective preference for skydiving or racecar driving. For the ATQ version, we replaced most of the items for this scale in an effort to remove the influence of fear on responses. One might enjoy the idea of skydiving, for example, Temperament and the Big Five 7 while also being fearful of jumping from an airplane. A new sociability scale was defined as enjoyment from interacting and being in the presence of others, distinguished from fearful and shyness in interactions with others (see Buss, 1991, for a discussion distinguishing sociability from shyness). In addition to high intensity pleasure and sociability, scales assessing positive affect (intensity, duration, frequency, rate of onset, and rising intensity of pleasure) and activity level were also included. Rothbart, Derryberry, and Posner (1994), in the tradition of Thomas and Chess (1977), view attentional processes as components of temperament. Effortful attention and cognitive sensitivity constructs were included in the initial development of the ATQ. Factors labeled effortful control have emerged from analyses of two caregiver report questionnaires developed by Rothbart and colleagues: the CBQ (Ahadi et al., 1993; Rothbart et al., 1994; Rothbart et al., 2001) and the Early Childhood Behavior Questionnaire (ECBQ: Putnam et al., 2001). In addition, a robust effortful control factor emerged from analysis of a revision of a self-report measure, the Early Adolescent Temperament Questionnaire (Capaldi & Rothbart, 1992; Ellis & Rothbart, 2001). The PRQ (Derryberry & Rothbart, 1988) also included scales assessing effortful control at the adult level. The initial ATQ did not include behavioral control scales (e.g., inhibitory control). Hence, the Study One effortful control construct is labeled effortful attention (a narrower construct). In addition to attentional shifting and focusing scales from the PRQ, attentional shifting from punishment (ability to control attention in the face of negative emotions and thoughts) and attentional shifting from reward (ability to control attention in the face of distracting positive emotions and desires) were added. These scales were intended to explore the structure of an effortful attention factor, as well as ways in which attentional control may interact with positive and negative emotionality. Temperament and the Big Five 8 A second broad construct from the PRQ was related to cognitive sensitivity. It included constructs of external perceptual sensitivity (awareness of slight, low intensity stimulation arising from the external environment), internal perceptual sensitivity (awareness of slight, low intensity stimulation arising from within the body), and cognitive reactivity (general internal cognitive activity). Our interest was in exploring the separability of reactive and effortful attentional processes, and breadth of sensitivity was emphasized in the ATQ. The cognitive reactivity scale was replaced with associative sensitivity, defined as the frequency, diversity, and remoteness of automatic conscious content not related to standard associations with the immediate environment. We were also interested in exploring the extent to which affective awareness could be empirically differentiated from the motivational-emotional constructs. Thus, an affective perceptual sensitivity scale (awareness of affect associated with low intensity stimuli) was also included, and the general construct was labeled cognitive sensitivity. Altogether, cognitive sensitivity included scales for external perceptual sensitivity, internal perceptual sensitivity, associative sensitivity, and affective perceptual sensitivity. Table 1 shows the scales based on sub-constructs associated with each of the four general motivational-emotional and attentional constructs discussed above, and Appendix A lists scale definitions with sample items for the scales in both studies. We used factor analysis to investigate a possible hierarchical structure of these scales. A second goal of this research was to explore relations betwen temperament and the Big Five of personality. In recent years, considerable research on personality has supported a fivefactor model. Common labels for the five factors with their corresponding factor numerals are extraversion (I), agreeableness (II), conscientiousness (III), neuroticism versus emotional stability (IV), and (V) intellect or imagination, or openness in the Five Factor Model (McCrae, Temperament and the Big Five 9 1993-1994). The label Big Five is generally reserved for measures derived from analysis of the trait-descriptive lexicon, whereas McCrae and Costa’s approach is referred to as the Five Factor Model (FFM). The Big Five and FFM structures are highly convergent (see McCrae & John, 1992), and we refer to the structure as the Big Five/FFM. Appendix B shows the labels for the Big Five domains along with the 40 Mini-Markers (i.e., eight trait-descriptors as markers for each of the five domains; see Saucier, 1994) used in these studies. Previous research has linked measures of temperament with the Big Five/FFM. For example,using adult subjects, Angleitner and Ostendorf (1994) evaluated the Big Five/FFM in relation to several temperament questionnaires, including a version of the Strelau Temperament Inventory (Strelau, Angleitner, Bantelmann, & Ruch, 1990), the EASI-III Temperament Survey (Buss & Plomin, 1975), the Sensation-Seeking Scale (Zuckerman, Eysenck, & Eysenck, 1978), and the Dimensions of Temperament Survey (Windle & Lerner, 1986). The authors report fiveand six-factor solutions that are similar to the Big Five/FFM as evidenced by loadings of scores on the Big Five/FFM measures. The six-factor solution included an additional rhythmicity factor. As the authors note, however, including the Big Five/FFM domain was likely to bias the factor structure in favor of the Big Five/FFM. They therefore included a factor analysis without the Big Five/FFM measures. A five-factor solution of the temperament scales included a similar pattern of loadings for these scales as in the six-factor solution, except that content associated with agreeableness and neuroticism in the other solutions loaded on the same factor. The factor scores from this solution were then correlated with factor scores from the six-factor solution that included analysis of the Big Five/FFM measures. These correlations were high, but consistent with only four factors in the temperament analyses as similar to the Big Five/FFM. Angleitner and Ostendorf (1994) did not, however, report correlations between measures defined Temperament and the Big Five 10 exclusively as temperament and measures exclusively defined as Big Five/FFM measures. They also aggregated multiple measures of temperament, rather than including well-defined temperament constructs. One of the goals of the current research is to investigate the relations between specifically defined theoretical constructs and the Big Five. The studies included in the current report were thus motivated by the desire to explore the hierarchical relations among lower level constructs of temperament, and to relate temperament constructs to the lexical Big Five model of personality. To accomplish these goals, we included older PRQ scales, modified others, and added new temperament scales. Factor analysis was used to investigate hierarchical relations among temperament variables. Factor scores derived from this model were then compared to scores from Saucier’s (1994) Mini-Marker measure of the Big Five. Method Participants A sample of 210 University of Oregon undergraduate psychology students filled out the first version of the Adult Temperament Questionnaire (ATQ-1) and the Mini-Marker measure of the Big Five. Subjects received credit toward their psychology courses for participating. Three subjects who did not complete the questionnaire were excluded. Thus, 207 subjects’ responses were analyzed. Gender information was not collected for the first study. Adult Temperament Questionnaire (Version 1) Each version of the ATQ used a Likert-scale ranging from one to seven, with a response of one indicating the item does not describe the person, and seven indicating an item to be highly descriptive of the person. A middle response of four on the scale indicated the subject believed the item to be neither descriptive nor non-descriptive. Items from the same scale were not placed Temperament and the Big Five 11 adjacent to each other. The first version of the Adult Temperament Questionnaire (ATQ-1) included 16 temperament scales, each composed of 11 to 16 items. The ATQ-1 contained 214 items, with 77 items taken from the PRQ. Six of the scales were virtually identical to the PRQ (frustration, discomfort, attentional shifting, attentional focus, internal perceptual sensitivity, and external perceptual sensitivity), three were substantially modified (fear, sadness, high intensity pleasure), and seven were new (sociability, positive affect, activity level, attentional shifting from reward, attentional shifting from punishment, affective perceptual sensitivity, and associative sensitivity). Appendix A gives scale definitions along with sample items. Big Five Mini-Markers Saucier's (1994) “Mini-Markers” (i.e., 40 trait-descriptors) were used to measure the lexical Big Five. Eight trait-descriptors were used to represent each of the five domains. The “Mini-Markers” have acceptable reliability and are derived from and thus highly correlated with Goldberg’s (1992) set of 100 markers that measure the domains of the Big Five. Saucier and Goldberg (2003) have developed alternative marker sets that they believe have improved upon both Goldberg’s 100 marker set and Saucier’s Mini-Marker measures of the Big Five. However, at the time data was collected, these alternative measures were not available. Appendix B displays the Mini-Marker items. Using a Likert-scale ranging from one to nine, subjects rated themselves on trait-descriptive words. The 40 trait-adjectives were presented in alphabetical order. Results Reliability coefficients were computed for each scale followed by exploratory factor analysis (principal axis) of the scale scores. Oblique rotations (promax) were used to allow exploration of relations among factors. The resulting factor scores were then related to the Temperament and the Big Five 12 measures of the Big Five domains. One item from each of three scales was removed to improve reliability. Final alpha coefficients of reliability ranged from .61 to .84. Alpha coefficients of reliability, means, and standard deviations of temperament and Big Five scales are reported in Table 2. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were both used for modeling this data. For all factor analyses reported in this paper, SPSS was used to perform the EFA, and the structural equation modeling software AMOS (a supplement to the SPSS program) was used to conduct the CFA. We extracted two-, three-, four-, and five- factor EFA solutions. Since there were four general constructs, the four-factor solution was of particular interest. A four-factor maximum likelihood CFA was then performed to see how well the data fit the model, and to compare the fit of alternative models. Chi-square, Joreskog and Sorbom’s Goodness of Fit Index (GFI), the Adjusted Goodness of Fit Index(AGFI,), and the Root Mean Square Error of Approximation (RMSEA) fit indices will be reported. The ChiSquare is rarely informative for these types of models (i.e., virtually all models are rejected), but is by convention usually reported. Fits of .90 are generally considered good for the GFI (Bollen, 1989) The AGFI is generally lower than the GFI, and rewards simpler models with greater degrees of freedom. The RMSEA can be thought of as a badness of fit index in that higher numbers indicate less fit. The RMSEA does not penalize for model complexity, and the fit is always lower for simpler models. Browne and Cudeck (1993) report that an RMSEA greater than .10 is generally not considered to be a good model. Four-Factor Model of Temperament Four factors were extracted based on the four general constructs explored, and the eigenvalue greater than one criterion, which suggested a four-factor structure. The pattern matrix for this four-factor solution is shown in Table 3. This model corresponded strongly to the Temperament and the Big Five 13 initial four general constructs. Factor I, labeled Effortful Attention, included loadings from attentional shifting from reward, attentional shifting from distress, attentional focusing, and attentional shifting. Factor II, labeled Cognitive Sensitivity, included loadings from internal perceptual sensitivity, affective perceptual sensitivity, external perceptual sensitivity, associative sensitivity, and a small secondary loading from sadness. Factor III, labeled Extraversion/Surgency, included loadings from high intensity pleasure, sociability, positive affect, and activity level. Factor IV, labeled negative emotionality, included loadings from fear, discomfort, sadness, and frustration. Correlations among these factors showed extraversion/surgency to be positively correlated with cognitive sensitivity (r = .56), and negative affect negatively correlated with effortful attention (r = -.50). There was also a modest negative correlation between negative affect and extraversion/surgency (r = -.26). Other correlations were close to zero. The CFA solution is reported in Table 4. The initial solution resulted in frustration having the lowest loading (.44 on negative affect). This was also true with the EFA in Table 3. All other loadings were at least .53. The Chi-Square for this model with 98 degrees of freedom was 326.89 (p = .000), suggesting rejection of the model. However, this statistic is not usually informative for these types of models (i.e., virtually all models would be rejected). The GFI was .84, AGFI was .77, and RMSEA was .11. These fits are considered less than optimal by some structural equation modeling standards (GFI > .90 and RMSEA <.10). This model is based on the assumption that all secondary loadings are zero. After reviewing the modification indices, and adding sadness, a double-loading scale, as an indicator of cognitive sensitivity, an improved GFI of .87, AGFI of .81, and an RMSEA of .09 were found (No Table reported for this solution). This model looks very much like the exploratory factor pattern in Table 3. Temperament and the Big Five 14 Successive iterations of models based on modification indices resulted in assigning the following additional parameters: attentional shifting from reward as an indicator of extraversion/surgency, internal perceptual sensitivity as an indicator of negative affect, attentional shifting as an indicator of cognitive sensitivity, and activity level as an indicator of effortful control (Table not reported). All of the model modifications were secondary loadings, and all were modest with the exception of a .50 loading of sadness onto cognitive sensitivity. The loadings associated with the initial model are substantially higher than loadings derived from adapting the model. The fit of this model had an improved GFI of .90, an AGFI of .85, and an RMSEA of .07, thus indicating the model fits the data reasonably well. When each general construct’s scales were averaged to form a general construct level scale, correlating with identically labeled factor scores at .93 or higher (i.e., effortful control = .99, cognitive sensitivity = .98, positive emotionality = .96, and effortful attention = .93). Therefore, it is clear that the factors emerging from EFA are highly convergent with our initial general construct scales. Comparison of the Four-Factor Models with Alternative Models The two-factor EFA structure included highest loadings from extraversion/surgency and cognitive sensitivity scales on the first factor, and highest loadings from effortful attention and negative affect (negative loadings) scales on the second factor. A CFA model based on assigning this pattern of loadings resulted in a GFI of .74, an AGFI of .63, and an RMSEA of .14. Although this model did not fit as well as our initial four-factor model without modifications (GFI = .84 and RMSEA of .11), the model is interesting in that it shows coherent links between motivational-emotional and cognitive-attentional constructs. The three-factor EFA model resulted in the negative affect scales scattering across the other three factors. A CFA model based on this pattern of loadings had a GFI of .76, AGFI of Temperament and the Big Five 15 .68, and RMSEA of .13. This model clearly did not fit the data as well as the four-factor model. The five-factor solution resulted in a frustration and activity scales loading onto a fifth factor, whereas the other highest loadings were consistent with the initial four-factor structure. The CFA based on this model had a GFI of .84, an AGFI of .77, and an RMSEA of .10. In subsequent analyses, however, we have used the four-factor model. Although this model fit about as well as the hypothesized four-factor model, it was basically the same as the four-factor model, and the fifth factor was not informative. Four Factor ATQ Model in Relation to the Big Five Table 5 shows correlations between the factor scores derived from the four-factor temperament solution and the lexical Big Five scales. The factor scores for each general construct of temperament are related to specific Big Five measures, with these correlations ranging from .43 to .59. Temperamental extraversion was most highly correlated with Big Five extraversion (r =.59), and negative affect with neuroticism (r = .53). The cognitive sensitivity and intellect/openness factors were also positively related (r = .55). Factor scores derived from the effortful attention factor showed the lowest correlation with a Big Five scale (.43 correlation with conscientiousness), as well as a correlation with Big Five neuroticism (-.34). Note in the bottom half of Table 5 that the correlations between general constructor factor scales and the Big Five scales are virtually the same as the comparison between factor scores and Big Five scales, thereby indicating that initial development of general constructs converged substantially with the Big Five independent of conducting factor analysis. Discussion The four-factor EFA solution showed substantial convergence with the existence of four broad constructs, demonstrated by 1) the emergent EFA four-factor solution, 2) the correlation between the EFA factor scores and the initial construct scales, and 3) the CFA analyses. The Temperament and the Big Five 16 four-factor structure includes the three factors Rothbart and colleagues (Ahadi et al., 1993; Putnam et al., 2001; Rothbart et al., 1994; Rothbart et al., 2001) found in toddlers and children (extraversion/surgency, negative affectivity, and effortful control). In addition, refinement of the central reactivity scales included in the PRQ resulted in a clear cognitive sensitivity factor. The modest secondary loading from sadness on cognitive sensitivity in the EFA and the modified CFA solutions replicated the three- and six-factor structures of the PRQ study, where sadness loaded on both a negative affect factor and a factor including perceptual sensitivities and cognitive reactivity scales. Factor scores from the four-factor model were substantially correlated with four of the Big Five domains, and this was true when comparing the Big Five to either factor scores or scales derived from initial construction independent of factor analysis. Ahadi and Rothbart’s (1994) proposed relations between temperament and Big Five factors were supported, with extraversion/surgency aligned with extraversion, negative affectivity with neuroticism, and effortful control with conscientiousness. In addition, the cognitive sensitivity factor scores were highly correlated with intellect/openness and moderately correlated with extraversion. This finding linking cognitive sensitivity to intellect/openness suggests that cognitive sensitivity (i.e., awareness of peripheral stimuli and remoteness of associations) is related to insight, reflection, and imagination. The richly textured, abstract trait-descriptors related to intellect/openness (e.g., intellectual, deep, creative, imaginative, and philosophical) thus may involve a common cognitive-attentional substrate. Correlations among the four factors are also consistent with a two-factor solution, with a high positive correlation between extraversion and cognitive sensitivity corresponding to the first factor, and a high negative correlation between negative affect and effortful control corresponding to the second factor. The two-factor solution and correlations among the four- Temperament and the Big Five 17 factors supporting this two-factor structure, are also consistent with the pattern of loadings on Digman’s (1997) higher order two-factor model derived from factor analysis of Big Five-related scales. Neuroticism (a correlate of negative affect) and conscientiousness (a correlate of effortful control) loaded onto one factor (along with agreeableness; agreeableness-affiliativeness content will be addressed in our Study Two), and extraversion (related to temperamental extraversion/surgency) and intellect/openness (related to cognitive sensitivity) loaded onto the other factor. An extensive literature is consistent with the high negative correlation between negative affect and effortful attention (e.g., Derryberry & Rothbart, 1988; Eysenck & Eysenck, 1985; Rothbart et al., 2001). For example, studies using the emotional Stroop task have repeatedly suggested that negative semantic information interferes with executive attentional processing (Dawkins & Furnham, 1989; MacLeod & Hagan, 1992; Mogg, Bradley, & Williams, 1995; Myers & McKenna, 1996; Pratto & John, 1991). In addition, the Diagnostic and Statistical Manual of Mental Disorders: Fourth Edition (American Psychiatric Association, 1994) lists attentional difficulties as indicators of anxiety and depressive disorders. Other research is consistent with the high positive correlation between extraversion/surgency and cognitive sensitivity. Induction of positive affect results in more inclusive categorization of words and colors (Isen & Daubman, 1984), and positive affect has also been associated with generating more unusual and diverse word associations (Isen, Johnson, Mertz, & Robinson, 1985). In general, a more creative and broad ranging cognitive style is produced when positive affect is induced (Ashby, Isen, & Turken, 1999). Recent factor analyses of scales comprising the Infant Behavior Questionnaire – Revised (IBQ-R) also resulted in a first factor with loadings from both perceptual sensitivity and extraversion scales (Gartstein & Rothbart, 2003). Temperament and the Big Five 18 Differentiating Aggressive and Non-Aggressive Negative Affect Because the five-factor EFA, supported by the CFA, suggested an aggressive negative affect factor, so we were also interested in exploring the differentiation of aggressive and nonaggressive negative affect. At the adult level of self-report, Zuckerman (1997; Zuckerman et al., 1993) has identified superfactors that discriminate fear-anxiety and anger-aggression related constructs. However, some models of personality do not make this distinction at a higher level in the hierarchy. Tellegen and colleagues (e.g., Harkness et al., 1995; Tellegen, 1985; Watson et al., 1999) have extracted a factor labeled negative affect that includes both aggressive and fearful components. Costa and McCrae’s (1994) scales comprising neuroticism (e.g., anxiety, depression, and angry-hostility) are consistent with Tellegen’s (1985) model. Aggression under the Five Factor Model, however, is related to both neuroticism and the negative pole of agreeableness (e.g., Costa & McCrae, 1994). Aggression items are also included at the negative pole of Cloninger’s superfactor labeled cooperation (see Cloninger, Przybeck, Svrakic, & Wetzel, 1994). In Study One, we included only one anger-aggression related scale (frustration), so that a common factor for anger-aggression was not possible. The ambiguous status of angeraggression in relation to non-aggressive negative motivated us to empirically explore the differentiation of these constructs. Studying Affiliativeness and Aggressiveness as Basic Dimensions of Temperament In addition to further exploring aggressiveness scales, we were also interested in adding scales for affiliativeness, thus yielding six general constructs of interest: cognitive sensitivity, effortful control, extraversion/surgency, non-aggressive negative affect, aggressive negative affect, and affiliativeness. Rothbart and Derryberry (2002; Derryberry & Rothbart, 1997) have discussed six general constructs as core psychobiological dimensions of temperament, and suggest that the six Temperament and the Big Five 19 temperament dimensions are related to the Big Five. At another level of analysis, Saucier (2001) has speculated that a lexically derived seven-factor model might be the optimal representation of at least some indigenous language structures originating outside of northern Europe. Saucier notes the strong similarity between seven-factor solutions derived from natural language traitdescriptions in Hebrew and Filipino (languages that are not closely related). Saucier’s model also differentiates anger- and fear-related constructs at the factor level, and includes a general negative valence factor. Six of these seven factors are thus conceptually similar to the core psychobiological constructs of temperament described by Rothbart and Derryberry. The inclusion of affiliativeness as a dimension of temperament deserves special attention. Rothbart and colleagues (Derryberry & Rothbart, 1997; Rothbart, 1994; Rothbart, Ahadi, & Evans, 2000; Rothbart & Bates, 1998) have proposed affiliativeness as a dimension of temperament, although to date, it has been explored only in revisions of the Infant Behavior Questionnaire (Gartstein & Rothbart, 2003) and the Early Adolescent Temperament Questionnaire (Ellis & Rothbart, 2001). A few decades ago, behavioral scientists did not have evidence for affiliative brain systems (Panksepp, 1998). Social bonds were thought to emerge from reinforcement contingencies related to organisms receiving food, warmth, and protection from attachment figures. Based upon animal research findings, however, Panksepp (1998) has posited brain systems related to affiliativeness. He notes that an understanding of specialized neural substrates for social attachment and separation distress is beginning to emerge, and that these two systems can be viewed as evolutionarily and neurochemically related. In addition to Panksepp’s psychobiological modeling of affiliation, Cloninger (1998; Svrakic, Svrakic, & Cloninger, 1996) includes a reward dependency construct as a dimension of temperament based upon the need for close relationships with others. Temperament and the Big Five 20 Study Two In Study Two, scales for six general constructs were included (see Appendix A for scale definitions and sample items). These constructs included non-aggressive negative affect (fear, sadness, and discomfort), anger-aggressive negative affect (frustration, social anger, and aggression control), affiliativeness (emotional empathy, social closeness, and empathic guilt), extraversion/surgency (sociability, positive affect, and high intensity pleasure), cognitive sensitivity (affective perceptual sensitivity, general perceptual sensitivity, and associative sensitivity), and effortful control (effortful attention, activation control, and inhibitory control). Table 6 displays the scales associated with each of the six general constructs, and Appendix A lists scale definitions with sample items for the scales in both studies. Aggressive and Non-Aggressive Negative Affect In addition to the frustration scale from the original PRQ, the aggressive negative affect construct included scales assessing social anger (hostility felt toward other people) and aggression control (capacity to inhibit the behavioral expression of anger). In Study One, negative affect was uncorrelated with agreeableness. Ahadi and Rothbart (1994) nevertheless speculated that negative affect is negatively correlated with agreeableness. A possible reason for the absence of this finding in Study One was the lack of content assessing social anger. Thus a social anger scale was included in the present study. The components of non-aggressive negative affect included fear, sadness, and discomfort. Affiliativeness Affiliative scales assessing emotional empathy (affective response congruent with the feelings of others), empathic guilt (distress in response to self negatively affecting other people), and social closeness (feelings of warmth, closeness, interest and involvement with others) were developed. The goal in designing these scales was for each scale to be substantially Temperament and the Big Five 21 differentiated from the others while also sharing a higher-level definition (positive concern for others). Our goal was to explore whether these measures empirically clustered together suggesting a more general affiliativeness dimension. Extraversion, Effortful Control, and Cognitive sensitivity Extraversion included three scales that were also used in Study One: sociability, positive affect, and high intensity pleasure. The effortful control construct was differentiated into effortful attention and two behavioral control scales used in the PRQ: inhibitory control (ability to inhibit inappropriate behavior) and activation control (capacity to perform an action when there is a strong tendency to avoid it). The four effortful attention scales in Study One (attentional shifting, focusing, shifting from reward, and shifting from punishment) were highly intercorrelated, so their content was collapsed into a single effortful attention scale in Study Two. We believed that including the PRQ behavioral control scales with effortful attention would extend the breadth of the construct. Cognitive sensitivity included scales assessing general perceptual sensitivity, affective perceptual sensitivity, and associative sensitivity. These scales were taken from Study One, except that external and internal perceptual sensitivity were collapsed into a single general perceptual sensitivity scale (these scales were conceptually similar and highly correlated). Method A total of 258 undergraduate psychology students (150 women and 108 men) filled out the revised version of the Adult Temperament Questionnaire (ATQ-2), followed by completion of the Big Five Mini-Markers. English was the first language for 95% of the subjects and 91.5% identified the United States as their country of origin. The ATQ-2 included the changes from ATQ-1 described above, with a total of 253 items. Administration of the questionnaires was Temperament and the Big Five 22 identical to that in Study One. Subjects received participation credit toward their undergraduate psychology courses. Results Table 7 reports the means, standard deviations, and reliabilities for the temperament scales. A total of 3 items from the 253 original items in ATQ-2 were removed to improve reliability. After removal of these 3 items, the reliability as assessed by coefficient alpha for 13 of 18 of the temperament scales reached a level of .80 or higher, and only one scale was lower than .70 (inhibitory control at .66). The initial EFA and CFA approach to analyzing this data set was the same as in Study One. First an EFA was performed on all of the scales. A six-factor solution was extracted to examine its correspondence to the initially developed six constructs, but some of the factors deviated from the six constructs. Aggressive negative affect, cognitive sensitivity, and effortful control factors were consistent with initial construction, but the other scales were distributed across the other three factors in a less interpretable manner. Exploring the hypothesized sixfactor solution at the CFA level of analysis resulted in a solution that was not mathematically acceptable (i.e., not positive definite). The EFA of the five-factor solution was consistent with the initial construction, except that the aggressive and non-aggressive negative affect scales loaded on the same general negative affect factor. The pattern matrix for the five-factor solution is reported in Table 8. The first factor (negative affect) included loadings from scales assessing facets of both aggressive negative affect (frustration, aggression control, social anger) and non-aggressive negative affect (fear, discomfort, and sadness). Effortful attention and inhibitory control also loaded modestly and negatively on the first factor. Factor II included loadings from scales of cognitive sensitivity (affective perceptual sensitivity, general perceptual sensitivity, and associative sensitivity) along Temperament and the Big Five 23 with small positive secondary loadings from sadness and high intensity pleasure. Factor III included highest loadings from scales derived from the extraversion construct (sociability, high intensity pleasure, and positive affect) along with moderate loadings from social closeness and inhibitory control (negative loading), and modest secondary loadings from discomfort (negative loading) and emotional empathy. Factor IV included loadings from affiliativeness scales (emotional empathy, empathic guilt, and social closeness) along with a moderate secondary loading from aggression control and even smaller loadings from social anger (negative loading), fear, and positive affect. Factor V, the effortful control factor, included highest loadings from activation control and effortful attention along with a moderate loading from inhibitory control. Although inhibitory control is a sub-construct of effortful control, it loaded relatively equally onto effortful control, extraversion, and negative affect. The negative correlation between the negative affect and effortful control factors was replicated (r = -.50). The positive correlation between cognitive sensitivity and extraversion factors was also replicated, but the correlation was only .26 in this study. Both cognitive sensitivity and extraversion were modestly correlated with the affiliativeness factor (r = .28 and r = .20, respectively), and other correlations were close to zero. The five-factor CFA solution is reported in Table 9. The Chi-Square with 125 degrees of freedom was 588.40 (p = .000). The GFI was .78, an AGFI of .70 and an RMSEA of .12. This model did not fit as did the four-factor model from Study One. However, the EFA five-factor model is still similar to initial construction, except that aggressive and nonaggressive negative emotionalities were collapsed into a single scale, and there were a number of secondary loadings. However, it was the best fitting model. As noted, the six-factor construct-driven CFA model was not admissible. This was also true of the two-, three-, and four- factor CFA models derived form EFA analyses. Using the modification indices to improve the fit of the model in Study One Temperament and the Big Five 24 required very few modifications, and each of these modifications involved modest secondary loadings, with the exception of one moderate secondary loading. However, in the present study it would require virtually reconstructing the EFA model by freeing the majority of parameters. Although the alternative five-factor model emerging from EFA did not fit the data particularly well with the CFA, the factor scores from this five-factor EFA model did demonstrate strong one-to-one correlations with the five constructs, after collapsing aggressive and nonaggressive negative emotionality into the same construct, (affiliativeness, r = .90; positive emotionality, r = .93; negative emotionality, r = .97; effortful control, r = .97, and cognitive sensitivity, r = .99), demonstrating strong convergence between initial construction and the factors emerging from EFA. Correlations between Temperament and the Big Five Table 10 shows the correlations between the EFA temperament factor scores and the Big Five scales. The correlations indicate robust levels of one-to-one correspondence. The five correlations suggesting convergence with the Big Five range from .64 to .74. Only one additional correlation exceeded .35, the negative correlation between effortful control and neuroticism (r = -.41). The negative affect factor scores were highly correlated with Big Five neuroticism (r = .74), cognitive sensitivity factor scores with Big Five intellect/openness (r = .65), temperamental extraversion factor scores with Big Five extraversion (r = .67), and the affiliativeness factor scores with Big Five agreeableness (r = .69). The effortful control factor scores were highly correlated with Big Five conscientiousness (r = .64), while also having a substantial negative correlation (r = -.41) with Big Five neuroticism. Note that the temperament scale scores derived from initial construction independent of factor analysis show the same pattern and strength of correlation with the Big Five (correlations along the main diagonal ranging from .60 to .70). Temperament and the Big Five 25 Discussion Study Two demonstrated the emergence of five broad factors of temperament composed of negative affect, cognitive sensitivity, extraversion/surgency, affiliativeness, and effortful control. These factors emerged from the EFA as an alternative to the hypothesized six-factor solution, and the CFA showed modest support for this model. Although the fit indices were not as high as Study One, it was the only model that fit the data. In addition, the factor scores from the EFA factor model were very highly convergent with initial construction, except that aggressive and non-aggressive negative affect constructs were collapsed into a single negative affect construct. Contrary to expectations, aggressive and non-aggressive negative affect scales loaded together on the same factor. Unlike Study One, however, there were several instances of secondary loadings. Although several of the scales in Study Two differed from those used in Study One, the conceptual nature of the four factors from Study One was replicated, and the affiliativeness construct introduced in Study One resulted in a fifth factor labeled affiliativeness. The factors showed substantial levels of convergence with the Big Five, and although the CFA indices did not suggest exceptional fit, scales derived from initial construction of factor breadth scales were highly correlated with the EFA factor scores (i.e., r  .90). High correlations were observed between temperament and Big Five, suggesting substantial convergence between five-factor models. We suggest that temperamental processes might be at the core of Big Five domains that were derived without theoretical assumptions. Both the EFA factor scores and general scale scores derived independent of factor analysis showed strong one-to-one correlations with the Big Five. The high negative correlation between negative affect and effortful control was replicated, and the positive correlation between extraversion/surgency and cognitive sensitivity Temperament and the Big Five 26 to a lesser degree. However, both the negative association between effortful control and negative affect and the positive association between cognitive sensitivity and extraversion/surgency were supported by the two-factor EFA structure, as was the case in Study One. As noted in Study One, these results may be related to experimental findings differentially linking positive and negative emotions with aspects of cognitive-attentional processing. The introduction of affiliativeness content also resulted in an affiliativeness factor showing a modest positive correlation with both cognitive sensitivity and extraversion. In this study, inhibitory control loaded relatively equally across effortful control, extraversion (negatively), and negative affect (negatively) factors. Social closeness also loaded relatively equally on both affiliativeness and extraversion factors, and there were also several other modest secondary loadings. We now consider these findings. Inhibitory Control All of the inhibitory control items explicitly refer to the capacity to inhibit behavior involving positive affect and approach. Therefore, although the scale fits the definition of effortful control, its negative loading on an extraversion/surgency factor (defined as positive affect and approach; see Derryberry and Rothbart, 1997) is, after the fact, not surprising. People who have stronger approach tendencies are more likely to find it difficult to inhibit approach tendencies. In addition, the negative loading of inhibitory control on a negative affect factor is consistent with other findings showing negative affect and effortful control to be negatively related (Ahadi et al., 1993; Derryberry & Rothbart, 1988; Ellis & Rothbart, 2001). Affiliativeness Scales assessing social closeness, emotional empathy, and empathic guilt clustered together forming an affiliativeness factor in Study Two. However, social closeness loaded equally on both affiliativeness and extraversion factors. This finding may be related to one of Temperament and the Big Five 27 our initial motivations for exploring affiliativeness as a dimension of temperament, namely that affiliation is often viewed as a facet of extraversion (e.g., Depue & Collins, 1999). Sociability (enjoyment from interacting and being in the presence of others) and social closeness (interest, warmth, and involvement with others) were highly correlated (r = .58). However, sociability loaded exclusively on the extraversion factor, whereas social closeness loaded equally on both affiliativeness and extraversion. This pattern of results suggests that having close relations with others is linked to both extraversion/surgency and affiliativeness, whereas the experience of sociability (enjoyment when among people) appears to be more purely a component of extraversion/surgency, perhaps through mechanisms of reward reactivity. In a study across 39 countries, Lucas, Diener, Grob, Suh, and Shao (2000) found support for reward sensitivity rather than sociability as basic to defining extraversion. Although emotional empathy loaded highest on the affiliativeness factor, this scale also loaded modestly on the extraversion factor, even though the majority of emotional empathy items were concerned with negative affect. The scale did not load on the negative affect factor. Emotional empathy was also empirically differentiated from the conceptually similar affective perceptual sensitivity scale. Emotional empathy is defined as experiencing emotions congruent in valence with others, whereas affective perceptual sensitivity items involve awareness of affect, including many items that involve awareness of incongruency between affect and social presentation. The distinction between emotional empathy and affective perceptual sensitivity (or “cognitive empathy”) is supported by emotional empathy’s loading on a motivational-emotional factor (affiliativeness) and affective perceptual sensitivity’s loading on a cognitive-attentional factor (cognitive sensitivity). The affiliativeness factor also included an interesting pattern of loadings from negative affect scales. Aggression control, which loaded highly on negative affect (negative loading) Temperament and the Big Five 28 loaded moderately on affiliativeness, suggesting that the capacity to inhibit aggression increases with higher levels of affiliativeness. Social anger, loading highest on the negative affect factor, also had a modest negative loading on affiliativeness. Finally, the modest positive loading of fear on affiliativeness suggests differential associations between fearful and aggressive negative affects in relation to affiliativeness. As in Study One, the highest loading of discomfort was on negative affect, but in this study there was also a noteworthy negative loading from discomfort on extraversion. High intensity pleasure and discomfort are quite similar in their definitions, except that the former refers to positive affect in response to intense and complex stimuli, whereas the latter refers to negative emotions in response to sensory stimulation. Eysenck and Zuckerman (see Zuckerman, 1997) were both influenced by constructs involving optimal level of stimulation in their early theorizing related to extraversion. In this study, there is thus modest evidence linking extraversion to optimal level of stimulation. Also, as in both the PRQ study and Study One, cognitive sensitivity had a modest loading from sadness. Rationale for Study Three Our analyses showed support for a five-factor model at both the EFA and CFA levels of analyses, with aggressive and non-aggressive negative affect sub-constructs collapsing into a single negative affect factor, suggesting that the factor structure found in Study One is representative. However, since this model was generated post hoc, we explored confirmation of this model in another sample. In addition, although the model was supported by EFA and CFA at moderate levels, some of these scales loading on more than one factor lessened overall fit. These deviations had interesting post hoc explanations discussed above. With respect to model refinement and further exploration, it also makes sense to delete these multiple loading scales from the model, so that Temperament and the Big Five 29 each scale is more exclusively representative of a single general construct. Therefore, we explored the model further after deleting these multiple loading scales. Finally, our data in Studies 1 and 2 was limited to college students of approximately the same age, cohort, and level of education. Study Three data was collected from a larger community sample that was substantially older and more diversified. Study Three The primary goal for Study Three was to explore replication of Study Two findings in a large community sample. A special version of the ATQ was constructed for participants in the Eugene-Springfield Community Sample. The goals for constructing this measure included: 1) using primarily the same constructs as Study Two; 2) constructing a short form; 3) eliminating scales that loaded substantially on more than one factor; and 4) developing a measure that could be used to further explore relations between temperament and the five-factor model. The above goals were also considered with respect to developing a measure that could be administered in a short period of time as a part of the biannual collection of data in the Eugene-Springfield Community Sample (see Goldberg, 2003). This 100-item version of the ATQ is a subset of items and scales from Study Two. The structure of the items was also changed to fit the typical format used by Goldberg (2003) with the Eugene-Springfield Community sample. Pronouns and other unnecessary words were omitted from items. For example, the fear item, “I become easily frightened.” was changed to “Become easily frightened.” However, the meanings of the items were not changed, and it is not likely that the changes in item structure would have influenced responding significantly. Table 11 displays the five general construct scales and their corresponding scales. Empirical Refinement of the Model Temperament and the Big Five 30 In Study One, the EFA and the CFA supported the initially constructed four-factor model. In Study Two, the EFA and the CFA showed substantive convergence with initial construction, but with notably more deviations from the model as well. One way to explore improving the fit of at the confirmatory level of analysis is to remove double loading scales, and in the case of the six-factor EFA, model loadings that were more purely deviant. If such a model fit the data better, this would be an improved measure showing coherency within each domain as well as differentiation from other factors/constructs. The following scales were removed: Inhibitory control loaded on three factors, and social closeness equally on two factors. Discomfort had a secondary negative loading on extraversion/surgency, and aggression control and social anger (negative loading) both had secondary negative loadings on affiliativeness. Moreover, the exploration of a separable aggressive and non-aggressive negative emotion constructs was no longer of central concern based on the five factor findings. We now present confirmation of this model in the community sample. Table 12 shows the ATQ general constructs and associated sub-constructs assessed in this study. No new scales were included, but aggression control, social anger, discomfort, inhibitory control, and social closeness were omitted, permitting development of a much shorter ATQ form. Costa & McCrae’s NEO-PI-R (1992b; McCrae & Costa, 1996; McCrae et al., 1996) was also included. The NEO-PI-R includes is a 240 item questionnaire measure of the Big Five/FFM domains, and each domain of the NEO-PI-R domains includes six facet scales that each include eight items. Costa & McCrae’s (1992b) NEO-PI-R measure of the Big Five/FFM domains had been completed by this community sample about eight years prior, in 1994. Temperament and the Big Five 31 Method Participants and Measures A total of 700 participants from a Eugene-Springfield, Oregon community sample completed this special 100-item version of the ATQ. The majority of these subjects have also completed a large number of questionnaires during the past decade, including questionnaires associated with the prominent models of personality discussed in the introduction to this chapter. The Eugene-Springfield Community Sample is managed by Goldberg (2003), and originally included 1,062 participants (700 of whom completed this version of the ATQ). Participants were recruited by mail solicitation in 1993 from lists of local homeowners. Data was collected through the mail. Age and gender data was known for 693 of the 700 people. Participants included 296 men, 397 women, and seven of unknown gender, and ranged in age from 26 to 91 years with a median of 57 and a mean of 58.7 years. Only 30 participants were younger than 40 years of age. Special Short Form of ATQ A 100-item ATQ questionnaire was adapted from the version of the ATQ used in Study Two, as described previously. Scales included 6 to 8 items each. To be consistent with other questionnaires completed by the community sample, this version of the ATQ used a 5-point Likert-scale instead of the previously used 7-point scale. This version of the ATQ was completed in 2002, and included two additional scales that were not of interest in this study. Results Table 12 reports the means, standard deviations, alpha reliability coefficients, and number of items for each of the scales. Table 13 reports the EFA of the 13 scales. Note that all the loadings from scales load highest onto factors consistent with the initial construction, with only one noteworthy secondary loading. In addition to loading highest onto Temperament and the Big Five 32 extraversion/surgency, positive affect also loaded negatively on negative affect. The CFA loadings are reported in Table 14. The Chi-Square for this model with 55 degrees of freedom was 359.86 (p = .000). The GFI was .93, and the AGFI was .88, substantially higher than in Studies One and Two, even after modifying the model. In addition the RMSEA was in the acceptable range at .09. The EFA and CFA results replicate the four-factor structure from Study One, as well as the five-factor structure from Study Two. This replication was from a larger and more diversified community sample, suggesting that replication generalizes beyond the limited samples in Studies One and Two. Table 15 reports the correlations between temperament factor and scale scores in relation to the general domain or factor breadth scales of the NEO-PI. Note that factor scores derived from the EFA show one to one correspondence, with correlations of .59 or higher, except for the affiliativeness and agreeableness correlation, substantially lower at .49. The correlations between temperament scale scores and the NEO-PI-R scales were similar, demonstrating that initial construction maps substantially onto the Big Five/FFM. General Discussion In Study One, four-factor EFA and CFA models resulted in substantial convergence between initial construction of constructs and empirical structure. Factor scores derived from a four-factor solution were substantially correlated with four of the five Big Five domains. In Study Two, the five-factor solution included conceptual replication of the four-factor solution from Study One, with added affiliativeness content resulting in a fifth factor. Factor scores derived from this model showed high levels of one-to-one correspondence with the Big Five scales, with correlations ranging from .64 to .74. General construct measures and Big Five scales were also related, with correlations ranging from .60 to .70. In Study One, correlations between Big Five scales and the temperament factor scores were not as high as in Study Two. Temperament and the Big Five 33 Part of this difference across studies appears to be the result of substantially higher reliabilities in Study Two. In Study Three, we explored empirical refinement of the five-factor model by removing multiple loading scales. This model was confirmed in a large-scale and more diversified community sample. Again, the temperament factor and general scale scores converged substantially with the Big Five/FFM. Convergence between Temperament Model and the Big Five How might analysis of thousands of trait descriptive words such as “kind,” “intellectual,” and “organized,” lead to a five-factor model of personality that is also linked to the organization of temperament? Digman and Shmelyov (1996) suggested that temperament could be subsumed under the Big Five. An alternative approach, however, is the possibility that the Big Five structure is shaped by early temperament. According to this view, since language is not sufficiently developed in infancy and early childhood, temperament in its earliest stages would not be influenced by explicit words a person used to describe the self and others. Later in development, explicit self-views (e.g., “I am not fearful.” or “I’m tough.”) will develop, influenced by and possibly influencing temperament. McCrae et al. (2000) make an argument for subsuming the Big Five/Five Factor Model under temperament. They note that behavioral genetics, animal personality, and stability across development and cultures all support this view. They also suggest that one aspect differentiating temperament and personality is that temperament researchers tend to emphasize basic processes such as attention and affect, whereas Big Five and Five Factor Model researchers emphasize prognostic outcomes, as in using conscientiousness to predict job performance. Personality researchers also often stress the effects individual differences have on others, especially in the agreeableness construct (Hogan, 1995). Temperament and the Big Five 34 In agreement with McCrae et al.’s (2000) analysis, we propose that basic temperament processes may form the substrate of global personality traits. Thus, effortful control can be seen as an attentional substrate for conscientiousness and cognitive sensitivity as a substrate for intellect/openness. Similarly, distress proneness may be central to neuroticism, and a reward and incentive system to extraversion. Of course, our data are correlational and based upon the assumption that the temperament scales assess temperamental processes. Additional research is needed to support or refute this view. Another reason for giving temperament priority in interpretation is a developmental one. Many of the temperament constructs explored in this paper are conceptually related to constructs of temperament assessed early in life (Rothbart & Bates, 1998). If constitutionally based individual differences provide the core for the developing personality, we would expect them to be reflected in broad personality descriptions. An important contribution of further research will be to build a stronger bridge linking child temperament to adult personality. Diener (2000) notes that developmental researchers of temperament and adult personality have been relatively isolated from each other. This isolation is attributed to the difficulty of obtaining data linking child and adult personality. However, the temperament constructs we have found to be associated with the Big Five in the self-report were developed on the basis of those applicable to the child. Future longitudinal research will be required to more thoroughly examine these links. The temperament model developed here supports the validity of the Big Five in new ways. Several prominent personality theorists have questioned the validity of the Big Five (Block, 1995; Eysenck, 1991; Tellegen, 1993; Zuckerman, 1992), and Block’s argument deserves special attention. He notes that the Big Five is derived from factor analysis, and that no statistical technique should be given the power to decide which concepts will be used for personality assessment, especially when factor solutions are in many respects arbitrary. He Temperament and the Big Five 35 suggests that movement of the Big Five bandwagon be halted in favor of identifying its contents. This research addresses Block’s content concern. To the degree that temperament scales reflect constitutionally based processes, (and are a priori and rationally constructed rather than “identified” by factor analysis) their relation with the Big Five helps specify its content. Block (1995) also questions the centrality of the Big Five for its lack of dynamism, making the important point that motivational aspects of personality organize thinking and behavior with respect to goals. Although this research does not empirically examine the intraindividual structure of personality, our model suggests that basic attentional and affectivemotivational processes are related to the Big Five. This understanding allows for greater modeling of personality dynamics than is possible using only abstract labels like extraversion, agreeableness, conscientiousness, neuroticism, and intellect/openness. For example, effortful control includes the capacity to inhibit pre-potent positive (extraversion/surgency) and negative (negative affect) responses in favor of subdominant response tendencies; cognitive sensitivity involves noticing peripheral stimuli with emotional relevance (see Derryberry & Rothbart, 1997). Hence, reactive and effortful facets of attentional processing can be mapped dynamically in relation to the suppression and activation of positive and negative emotionality. In this paper, we have provided empirical evidence that scales assessing lower-level constructs demonstrate a structure reflecting higher-level constructs. Further, these general constructs show empirical convergence with global traits (i.e., the Big Five) developed from a very different lexical approach. It is hoped that this work will contribute to future research exploring developmental links between temperament and personality.

Temperament and the Big Five 65 Appendix A General Constructs and Definitions of Scales with Sample Items AFFILIATIVENESS Emotional Empathy: Affective response congruent with what others are perceived to feel. I am rarely bothered by the apparent suffering of strangers (coded in reverse). Empathic Guilt: Distress in response to negatively affecting other people. Whenever I believe that I have hurt someone’s feelings, I feel guilty. Social Closeness: Feelings of warmth, closeness, interest, and involvement with others. There are some people that I feel very close to. EFFORTFUL CONTROL (Effortful Attention in Study One) Activation Control: Capacity to perform an action when there is a strong tendency to avoid it. I hardly ever finish things on time (coded in reverse). Attentional Focusing: Capacity to focus attention on desired channels, thereby resisting unintentional shifting to irrelevant or distracting channels. My concentration is rarely disrupted if there is music in the room around me. Attentional Shifting: Shifting of attentional focus to desired channels, thereby avoiding unintentional focusing on particular channels. I often lose my train of thought when I have to keep track of several things at once (coded in reverse). Attentional Shifting from Punishment: Control over focusing and shifting of attention amid negative thoughts and negative emotions. When I need to focus my attention upon a task, fearful thoughts rarely distract me. Attentional Shifting from Reward: Control over focusing and shifting of attention in the face of distracting positive emotions and desires. If I am anticipating a rewarding activity, it is difficult for me to think of anything else (coded in reverse). Effortful Attention: Capacity to focus attention as well as to shift attention when desired. This scale includes the above four scales (attentional focusing, attentional shifting, attentional shifting from punishment, and attentional shifting from reward) collapsed together. Temperament and the Big Five 66 Inhibitory Control: Capacity to inhibit inappropriate behavior. It is easy for me to hold back my laughter in a situation where it is not appropriate. EXTRAVERSION/SURGENCY Activity Level: The rate of onset, level of intensity, frequency, endurance, and enjoyment of behavioral activity. Sometimes I feel as though I'm full of energy. High Intensity Pleasure: Pleasure related to situations involving high stimulus intensity, rate, complexity, novelty, and incongruity. I would not enjoy the sensation of listening to loud music with a laser light show (coded in reverse). Positive Affect: Latency, threshold, intensity, duration, and frequency of experiencing pleasure. It doesn't take much to evoke a happy response in me. Sociability: Enjoyment derived from social interaction and being in the presence of others. I usually enjoy being with people. NEGATIVE AFFECT Aggression Control: Capacity to inhibit the behavioral expression of anger. I do not have a problem in controlling hostile impulses. Discomfort: Unpleasant affect resulting from the sensory qualities of stimulation. I find loud noises to be very irritating. Fear: Unpleasant affect related to anticipation of pain or distress. Loud noises sometimes scare me. Frustration: Unpleasant affect related to the interruption of tasks and behavior. I seldom become irritated when someone is late (coded in reverse). Sadness: Unpleasant affect and lowered mood and energy related to object or person loss, disappointment, and exposure to suffering. I rarely feel sad after saying good-bye to friends or relatives (coded in reverse). Social Anger: Hostility felt toward other people. I rarely feel angry at people (coded in reverse). Temperament and the Big Five 67 COGNITIVE SENSITIVITY Affective Perceptual Sensitivity: Spontaneous emotionally valenced explicit cognition associated with low intensity stimuli. I am often consciously aware of how the weather seems to affect my mood. Associative Sensitivity: Spontaneous cognitive content that is not related to standard associations with the environment. When I am resting with my eyes closed, I sometimes see visual images. External Perceptual Sensitivity: Awareness of slight, low intensity stimulation arising from the environment. I often notice visual details in the environment. Internal Perceptual Sensitivity: Awareness of slight, low intensity stimulation arising from within the body. I usually fail to notice it when my muscles tense up just slightly (coded in reverse). General Perceptual Sensitivity: Internal and External Perceptual Sensitivity: Combined.
