Beneath the Surface: Uncovering the relationship between extraversion and organizational citizenship behavior through a facet approach

To date, an empirical link between the broad factor extraversion and organizational citizenship behavior (OCB) has not been found. We propose that a facet conceptualization of extraversion including surgency, sociability and positive emotions predict an individual's level of citizenship behaviors in opposing ways, thus masking the predictive ability of a broad factor of extraversion. In study one, we establish the foundation for predictive differences by documenting differential relationships between the facets of extraversion and the type of organizational cultures potential job applicants are attracted to. In study two, analysis of peer rated OCB from 117 individuals working in various organizations supports the superior predictive ability of the facets over that of the broad factor.     

The facets of anxiety sensitivity represented in the childhood anxiety sensitivity index: confirmatory analyses of factor models from past studies

Results of past factor analytic studies of the Childhood Anxiety Sensitivity Index and Anxiety Sensitivity Index were used to formulate hypotheses about factor models of anxiety sensitivity. Using a nonclinical sample of 767 children and adolescents and confirmatory factor analysis, hypothesized models with 2, 3, and 4 lower order factors (facets) were tested. Goodness-of-fit criteria indicated that a model with 4 facets fits these data well. Support was found for factorial invariance of the 4 facets across age and gender, using nonclinical and clinical samples. Results support a hierarchical factor model in that there was a strong general factor, explaining 71% of the variance. Findings are discussed in the context of anxiety sensitivity theory and research with children and adolescents.     

A quantitative review of the relations between the “Big 3” higher order personality dimensions and antisocial behavior

In this meta-analytic review, Hans J. Eysenck’s theory of criminality (Eysenck, 1964, Eysenck, 1977) serves as a theoretical framework for examining the relations between higher order personality dimensions and antisocial behavior (ASB). The three higher order dimensions examined are referred to as extraversion/sociability, neuroticism/emotionality, and impulsivity/disinhibition (see Sher & Trull, 1994), and they are likened to Eysenck’s dimensions of extraversion (E), neuroticism (N), and psychoticism (P), respectively (Eysenck & Eysenck, 1975) and Tellegen’s dimensions of positive emotionality (PEM), negative emotionality (NEM), and constraint (reversed) (CON), respectively (Tellegen, 1982). Ninety-seven samples, from 52 published and unpublished studies, were reviewed. The results indicated that among the “Big 3” personality dimensions, impulsivity/disinhibition is most strongly related to ASB and extraversion/sociability is least strongly related to ASB. Additional variables, including age and methodological differences, were found to moderate the associations between the personality dimensions and ASB.     

Why introverts can't always tell who likes them: multitasking and nonverbal decoding

Despite personality theories suggesting that extraversion correlates with social skill, most studies have not found a positive correlation between extraversion and nonverbal decoding. The authors propose that introverts are less able to multitask and thus are poorer at nonverbal decoding, but only when it is a secondary task. Prior research has uniformly extracted the nonverbal decoding from its multitasking context and, consequently, never tested this hypothesis. In Studies 1-3, introverts exhibited a nonverbal decoding deficit, relative to extraverts, but only when decoding was a secondary rather than a primary task within a multitasking context. In Study 4, extraversion was found to correlate with central executive efficiency (r = .42) but not with storage capacity (r = .04). These results are discussed in terms of arousal theories of extraversion and the role of catecholamines (dopamine and norepinephrine) in prefrontal function.     

Personality and antisocial behavior in children and adolescents: An enquiry into Eysenck's and Gray's theories

Two studies were conducted to test the hypotheses derived from Eysenck's and Gray's theories of personality regarding antisocial behavior. For this purpose the Eysenck Personality Questionnaire (Junior) (EPQ-Junior) and a card task aimed at measuring sensitivity to reward were used in each of the studies. The first study compared a group of juvenile delinquents with a group of nondelinquents and the second study compared a group of severely conduct-disordered children with a group of normal children. The results did not support Eysenck's claim that delinquents score higher than their normal counterparts on extraversion, neuroticism, and psychoticism. Some support was found for the hypothesis derived from Gray's theory: Children and adolescents with severe antisocial behavior were more sensitive to rewards than their normal counterparts.     

Associations Between Lower Order Facets of Personality and Dimensions of Mental Disorder

Although there is a plethora of research documenting the relations between broad personality traits and psychopathology, there is decidedly less on the relations between lower order facets and psychopathology. In the current study, we explored the associations between lower order personality traits and dimensions of mental disorder. A combined sample of undergraduates and outpatients completed self-reports of personality and mental disorder. Symptom counts of mental disorders were factor analyzed, and a higher order three-factor solution emerged. One factor was substance use disorder (SUD), and internalizing branched into distress and fear. These dimensions were regressed on facets from the Big Five model of personality. SUD was significantly predicted by high excitement-seeking from the extraversion domain and low self-discipline from conscientiousness. Distress and fear were indistinguishable from one another but showed a different pattern of relations from SUD. High anxiety and depression from neuroticism, low gregariousness from extraversion, high aesthetics and low actions from openness, low trust and high tender-mindedness from agreeableness, and low self-discipline from conscientiousness significantly predicted distress and fear. The findings demonstrate that lower order traits within a single domain have complex relations with psychopathology, which are shrouded when examining broad, higher order traits. Assessment and treatment implications are discussed.     

Adolescent mice,unlike adults,consume more alcohol in the presence of peers than alone

One hallmark of adolescent risk‐taking is that it typically occurs when adolescents are with peers. It has been hypothesized that the presence of peers primes a reward‐sensitive motivational state that overwhelms adolescents' immature capacity for inhibitory control. We examined this hypothesis using a rodent model. A sample of mice were raised in same‐sex triads and were tested for alcohol consumption either as juveniles or as adults, with half in each age group tested alone and half tested with their cagemates. The presence of ‘peers’ increased alcohol consumption among adolescent mice, but not adults. The peer effect on human adolescent reward‐seeking may reflect a hard‐wired, evolutionarily conserved process through which the presence of agemates increases individuals' sensitivity to potential rewards in their immediate environment.     

Extraversion: sociability and impulsivity?

The sociability and impulsivity components of extraversion were studied. Thirty experimental items were written to assess different aspects of sociability and impuslivity. These items, along with the 24 extraversion items of the MPI, were administered to 146 college students. Factor analyses of experimental items indicated that neither sociability nor impulsivity is unitary. Correlations among these sociability and impulsivity factors and the MPI extraversion items indicated that MPI extraversion is essentially a measure of one aspect of sociability: the quantity of social relationships. Extraversion touches on but does not adequately sample either the intensity (quality) of social relationships or aspects of impulsivity.

The relationship between the EPI extraversion score and impulsiveness on a perceptual-motor task

This paper describes an investigation of the relationship between extraversion and impulsiveness. These two traits were measured respectively by the Eysenck Personality Inventory (EPI) and the IES Arrow-Dot test. The subjects were 50 males and 50 females matched for age. Arrow-Dot impulsiveness was found to correlate significantly with extraversion in both samples. In the female sample Arrow-Dot impulsiveness correlated only significantly with the ‘impulsiveness’ component of extraversion. In the male sample both the ‘impulsiveness’ and ‘sociability’ components of the extraversion factor contributed about equally to its variance.     

Social influences on creativity: the effects of contracted-for reward

Three studies were conducted to examine the effects of reward on children's and adult's creativity. The primary hypothesis was that explicitly contracting to do an activity in order to receive a reward will have negative effects on creativity, but receiving no reward or only a noncontracted-for reward will have no such negative effects. All three studies provided support for this hypothesis. Moreover, this support appears to be strong and generalizable across different subject populations, reward types, reward presentations, and creativity tasks. Possible mechanisms for the phenomenon are discussed.     

The nature of extraversion: a genetical analysis.

A biometrical-genetical analysis of twin data to elucidate the determinants of variation in extraversion and its components, sociability and impulsiveness, revealed that both genetical and environmental factors contributed to variation in extraversion, to the variation and covariation of its component scales, and to the interaction between subjects and scales. A large environmental correlation between the scales suggested that environmental factors may predominate in determining the unitary nature of extraversion. The interaction between subjects and scales depended more on genetical factors, which suggests that the dual nature of extraversion has a strong genetical basis. A model assuming random mating, additive gene action, and specific environmental effects adequately describes the observed variation and covariation of sociability and impulsiveness. Possible evolutionary implications are discussed.     

Left Hemispheric Lateral Preference and High Neuroticism Predict Disinhibition in Two Go/No‐Go Experiments

Although disinhibition is widely implicated in impulse‐control‐related psychopathologies, debate remains regarding the underlying approach and avoidance processes of this construct. In two studies, we simultaneously tested three competing models in which varying levels of extraversion, neuroticism, and hemispheric lateral preference are associated with disinhibition. In both studies (Study 1, N = 92; Study 2, N = 124), undergraduate students were randomly allocated to one of two versions of the go/no‐go task: one where participants were primed through reward to make more “go” responses and another where no such priming occurred. Neuroticism, extraversion, and hemispheric lateral preference measures were also collected. Across both studies, disinhibition was greatest in individuals who reported both a left hemispheric lateral preference and high neuroticism. This pattern was only found for those who were primed through reward to make more “go” responses. There was no association with extraversion. Contrary to previous research, our results suggest that left hemispheric asymmetry and neuroticism and not extraversion drive disinhibited approach, following the establishment of a prepotent approach response set. This has salient implications for the theoretical understanding of disinhibited behavior, as well as for the study of continued maladaptive approach behavior.     

Reward sensitivity and substance abuse in middle school and high school students

In this study, the authors investigated the relation between reward and punishment sensitivity and adolescent substance use. The sample (N = 216; 130 girls, 85 boys) was drawn from high school and middle school students enrolled in a Midwestern suburban school district. Participants completed a substance use questionnaire and the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (R. Torrubia, C. Avila, J. Molto, & X. Caseras, 2001). For 13 of 15 types of substance abuse, students with high reward sensitivity and low punishment sensitivity showed the highest levels of use. This finding supports the hypothesis of an interaction effect between reward sensitivity and punishment sensitivity and suggests that individuals who are high in reward sensitivity but low in sensitivity to punishment may be at a higher risk for substance abuse.     

Anxiety sensitivity and the five-factor model of personality.

Relations between anxiety sensitivity (AS) and the higher-order and lower-order dimensions of the 'Big Five' model of personality were examined in 317 university students. AS was significantly associated with a number of personality domains and facets of the NEO-PI-R. Regression analyses indicated that only the higher-order domains of neuroticism and extraversion (negatively) and the lower-order N facets of anxiety and self-consciousness, significantly predicted AS. Three lower-order factors within AS were identified and were also compared to NEO-PI-R domains and facets. In a hierarchical regression, the three AS factors significantly predicted variance in a measure of panic-related anxiety after the effects of the six N facets were statistically controlled. Results are discussed in the context of previous work with a Big Three taxonomy of personality and implications for understanding the nature and possible origins of AS are outlined.     

What is the central feature of extraversion? Social attention versus reward sensitivity

R. E. Lucas, E. Diener, A. Grob, E. M. Suh, and L. Shao (2000) recently argued that the core of the personality dimension of Extraversion is not sociability but a construct called reward sensitivity. This article accepts their argument that the mere preference for social interaction is not the central element of Extraversion. However, it claims that the real core of the Extraversion factor is the tendency to behave in ways that attract social attention. Data from a sample of 200 respondents were used to test the 2 hypotheses with comparisons of measures of reward sensitivity and social attention in terms of their saturation with the common variance of Extraversion measures. The results clearly showed that social attention, not reward sensitivity, represents the central feature of Extraversion.     

Linking proactive personality and the Big Five to motivation to learn and development activity

The authors investigated links between the Big Five, proactive personality, and motivation to learn. Web-based survey data were collected at 2 points in time from 183 employees of a financial services firm. Results showed that proactive personality was, only in part, a composite of Big Five facets, which accounted for 26% of its variance. Structural equation modeling results demonstrated that proactive personality, openness, extraversion, and conscientiousness predicted motivation to learn. In addition, motivation to learn was positively related to objectively assessed development activity. Proactive personality, extraversion, and openness had significant indirect links to development activity. Hierarchical regression results suggested that proactive personality had significant incremental validity in the prediction of motivation to learn over all relevant Big Five facets.     

Three superfactors in the 16PF and their relation to Eysenck's P,E and N

The initial data consisted of responses to the 16PF and E.P.Q., obtained at the same testing, from 239 Independent Study Students. The responses to the 16PF were subjected to a principal components analysis. A Scree Test applied to the original solution indicated that between 8 and 10 factors should be retained for rotation. As this was at variance with Cattell's postulated factor structure supplementary analyses involving the retention and rotation of from 16 to 22 factors and item-factor analyses of groups of scales were carried out. All of these analyses failed to reproduce anything like a clear 16-scale structure. In order to accommodate the hypothesis that a 3-factor solution, in line with Eysenck's postulated dimensions of P, E and N, underpinned the Cattell scales and to test the validity of the intermediate solutions, 8, 7, 6, 5, 4 and 3 factors were retained and subjected to varimax and promax rotations. These solutions were compared with solutions obtained from analyses of the responses to the 16PF of 200 students at the Independent Assessment and Research Centre. Only the 3-factor solutions showed a degree of replicability across samples. The samples were combined to form a total sample of 439 cases and this was tested for factor replicability using factor comparability coefficients based on factor scores. This revealed a clear 3-factor structure, of anxiety, superego and exvia, which was replicable across sexes. An analysis of the responses to the combined questionnaires indicated that the neuroticism and anxiety factors and the extraversion and exvia factors were co-incident, but that psychoticism and superego were separate factors. However, the P-scale loaded -0.40 on the superego factor, which lends some support to Eysenck's contention that psychoticism is the obverse of superego. A 3-step analysis, in which pairs and triads of scales were tested for factor replicability, confirmed the equivalence of the neuroticism and anxiety factors and the extraversion and exvia factors. As far as psychoticism and superego were concerned only the latter appeared as a real, replicable factor. This factor contained virtually all the 16PF superego or S-items and 11 of the 25 E.P.Q. P-items. The 14 P-items which did not load significantly on the superego factor were those involving the cruelty or sadism element of the concept of psychoticism. It is contended that superego, rather than psychoticism, may best lay claim to join neuroticism and extraversion in what may be termed the great triumverate of the personality sphere.     

Differential relationships of extraversion,impulsivity, and sociability to study habits

Reanalysis of data on library study habits presented by J. B. Campbell and C. W. Hawley (Journal of Research in Personality, 1982, 16, 139–148) revealed differential utility for the EPI extraversion scale and its components, impulsivity and sociability. Individuals studying in locations that provided greater external stimulation had significantly higher extraversion and impulsivity, but not sociability, scores than individuals studying elsewhere in the library. Impulsivity was more strongly associated than sociability with preferred noise levels, frequency of study breaks, and importance and preferred levels of socializing opportunities, but less strongly associated with preferred levels of crowdedness. Findings are discussed in terms of the interpretation, reliabilities, and theoretical context of the subscales.     

A reappraisal of successive negative contrast in two populations of domestic dogs

When an anticipated food reward is unexpectedly reduced in quality or quantity, many mammals show a successive negative contrast (SNC) effect, i.e. a reduction in instrumental or consummatory responses below the level shown by control animals that have only ever received the lower-value reward. SNC effects are believed to reflect an aversive emotional state, caused by the discrepancy between the expected and the actual reward. Furthermore, how animals respond to such discrepancy has been suggested to be a sign of animals’ background mood state. However, the occurrence and interpretation of SNC effects are not unequivocal, and there is a relative lack of studies conducted outside of laboratory conditions. Here, we tested two populations of domestic dogs (24 owned pet dogs and 21 dogs from rescue kennels) in a SNC paradigm following the methodology by Bentosela et al. (J Comp Psychol 123:125–130, 2009), using a design that allowed a within-, as well as a between-, subjects analysis. We found no evidence of a SNC effect in either population using a within- or between-subjects design. Indeed, the within-subjects analysis revealed a reverse SNC effect, with subjects in the shifted condition showing a significantly higher level of response, even after they received an unexpected reduction in reward quality. Using a within-, rather than a between-, subjects design may be beneficial in studies of SNC due to higher sensitivity and statistical power; however, order effects on subject performance need to be considered. These results suggest that this particular SNC paradigm may not be sufficiently robust to replicate easily in a range of environmental contexts and populations.
