Realistic affective forecasting: The role of personality

Affective forecasting often drives decision-making. Although affective forecasting research has often focused on identifying sources of error at the event level, the present investigation draws upon the “realistic paradigm” in seeking to identify factors that similarly influence predicted and actual emotions, explaining their concordance across individuals. We hypothesised that the personality traits neuroticism and extraversion would account for variation in both predicted and actual emotional reactions to a wide array of stimuli and events (football games, an election, Valentine's Day, birthdays, happy/sad film clips, and an intrusive interview). As hypothesised, individuals who were more introverted and neurotic anticipated, correctly, that they would experience relatively more unpleasant emotional reactions, and those who were more extraverted and less neurotic anticipated, correctly, that they would experience relatively more pleasant emotional reactions. Personality explained 30% of the concordance between predicted and actual emotional reactions. Findings suggest three purported personality processes implicated in affective forecasting, highlight the importance of individual-differences research in this domain, and call for more research on realistic affective forecasts.     

Individual differences in personality and face identification

Unfamiliar face identification is characterised by substantial variation between individual observers, but the cause of this variation is largely unknown. This study investigated whether individual differences in face identification are linked to an observer's personality, by combining performance on an established face-matching test with two in-depth personality assessments (the 16PF5 and the NEO-PI-R). The face test revealed a broad distribution in identification ability, but associations between face perception and personality were found only in female observers. In this group, correct face identifications related to low anxiety, low tension, and high emotional stability. These results suggest that associations between personality and face perception are limited, and are confined to anxiety and facets of neuroticism.     

Hormones and personality: Testosterone as a marker of individual differences

Recently, testosterone (T) has been linked to behaviors that are conceptually related to dominance as a personality characteristic. Although evidence for this association is growing, the psychometric properties of T as an individual difference variable have been largely neglected. For T to be considered a biological marker of dispositional dominance it is critical that it demonstrates high test–retest reliability and good convergent and discriminant validity. Two studies tested the temporal stability of salivary T in humans and the relationship between T and traditional measures of personality. Across both studies, test–retest reliability for T was high and comparable to the short-term stability of questionnaire-based and implicitly assessed personality assessment instruments. In being modestly correlated with self-reported dominance, T showed some evidence of convergent validity. In being statistically independent from conceptually unrelated personality constructs (such as Emotional Stability and Openness to Experience) it showed good evidence of discriminant validity. The findings strengthen the psychometric foundation for using T as a hormonal marker of individual differences.     

Gender and autistic personality traits predict perspective-taking ability in typical adults

Adopting another’s visual perspective is exceedingly common and may underlie successful social interaction and empathizing with others. The individual differences responsible for success in perspective-taking, however, remain relatively undiscovered. We assessed whether gender and autistic personality traits in normal college student adults predict the ability to adopt another’s visual perspective. In a task differentially recruiting VPT-1 which involves following another’s line of sight, and VPT-2 which involves determining how another may perceive an object differently given their unique perspective (VPT-2), we found effects of both gender and autistic personality traits. Specifically, we demonstrate slowed VPT-2 but not VPT-1 performance in males and females with relatively high ASD-characteristic personality traits; this effect, however was markedly stronger in males than females. Results contribute to knowledge regarding ASD-related personality traits in the general population and the individual differences modulating perspective-taking abilities.     

Predicting employee attitudes to workplace diversity from personality,values, and cognitive ability

The current study assessed the predictive validity of broad and narrow measures of personality, values, and cognitive ability on employee attitudes to workplace diversity. Australian working adults (N = 731; 66% female; mean age = 43, SD = 12) completed the 200-item HEXACO Personality Inventory, Schwartz's Portrait Values Questionnaire, ACER measures of numeric, verbal, and abstract reasoning ability, the Attitudes Toward Diversity Scale, and four scales measuring prejudice towards female workers, ethnic workers, older workers, and workers with a disability. Results showed that Honesty–Humility, Extraversion, Openness, and cognitive ability (especially verbal) predicted more positive attitudes to workplace diversity. Valuing power, security, and tradition more, and valuing universalism less was associated with more negative attitudes to workplace diversity.     

She works hard for the money: Valuing effort underlies gender differences in behavioral self-handicapping

Research in the area of self-handicapping has consistently demonstrated a robust yet puzzling gender difference in the use of and evaluation of behavioral self-handicaps; women (1) are less likely to use these forms of handicaps, particularly those involving the actual or reported reduction of effort, and (2) evaluate the use of these handicaps by others more negatively than do men. The present research examines several possible explanations for these consistent gender differences and finds that the personal value placed on effort is an important mediator of these effects.     

Aggregate temperament scores from multiple countries: Associations with aggregate personality traits,cultural dimensions,and allelic frequency

Aggregate temperament scores were calculated across 17 studies for 18 countries. These scores were analyzed in relation to aggregate personality scores, cultural orientation, and allelic distribution reported in prior studies. Cross-culture patterns were largely consistent with those previously reported for personality: countries high on Surgency (SUR) were high on Extraversion, high Negative Affectivity (NEG) was consistent with Neuroticism, and Regulatory Capacity (RC) with Agreeableness. Regarding cultural orientation, aggregate SUR was associated with low Power Distance and Long-Term Orientation; NEG with low Individualism and high Masculinity and Uncertainty Avoidance; and RC with low Power Distance and Masculinity. Higher proportion of MAOA-uVNTR low expression alleles was associated with low SUR and low RC; and A118G G-form allele proportion with low RC.     

Where birds flock to get together: The who,what, where,and why of mate searching

An understudied area of personality psychology is how personality traits might facilitate structuring of one’s environment toward goals like mating. In four studies (N = 1325), we examined (1) self-reports of where individuals go to find long-term and short-term mates, (2) how personality traits are associated with the use of these locations, and (3) how the sexes differ in their selection of mate search locations. Men were more likely than women were to use short-term (e.g., bars) than long-term (e.g., community events) niches, but did not differ in success in those niches and agreed on the nature of those niches. Slow life history traits, conscientiousness and agreeableness, were linked to preferences for long-term niches whereas, fast life history traits, narcissism and dishonesty, were linked to preferences for short-term mating niches.     

Individual differences in the acceptance of stereotyping

Previous research has documented individual differences in a range of constructs relating to social stereotyping, prejudice, and intergroup attitudes. However, research has not sought specifically to measure a general acceptance of social stereotyping. In the present research, we explored attitudinal, cognitive, emotional, and personality correlates of a person’s self-reported willingness to rely on stereotypical information when interacting with people of different social and cultural groups. In six studies (N = 1080) we found that more acceptance of stereotyping was associated with more explicit and implicit stereotyping of particular groups, less liberal gender-role values, more authoritarian attitudes, preference for hierarchies, higher social dominance orientation, less universal outlook, less complexity in describing others’ emotions, less utilization of emotional information, and more utilization of social categories (gender and race) when rating the similarity of faces, less agreeable and more agentic personality, and more rigid and simplistic cognitive style (all independent of one’s gender). Female and African-American participants were less accepting of stereotyping than male and Caucasian participants. The general tendency to accept stereotyping in daily life is a measurable individual difference that may prove useful in social-personality research.     

Relationships between personality, attitudes and dietary behaviour in a group of Scottish adolescents

Dietary behaviours, dietary attitudes, dietary knowledge and personality were surveyed in a group of 451 Scottish schoolchildren aged 11–15 years. A factor analysis of the behaviour items gave a three-factor structure with factors designated Healthy Eating, Unhealthy Eating and Health Habits. A general healthy vs. unhealthy eating factor was also extracted. A factor analysis of the attitude statements gave factors designated Pickiness, Neophobia and Food Interest. Dietary knowledge was found to be positively correlated with Healthy Eating score and negatively correlated with Unhealthy Eating score. The personality trait of Psychoticism was positively correlated with Unhealthy Eating score and negatively correlated with dietary knowledge, whilst Neuroticism was significantly negatively correlated with Healthy Eating and Health Habits and significantly positively correlated with Pickiness and Neophobia. Gender and socio-economic status differences in behaviour and attitude factor scores are also reported.     

Belief in a just world and social dominance orientation: Evidence for a mediational pathway predicting negative attitudes and discrimination against individuals with mental illness

Prejudice against individuals with mental illness stems from multiple factors, including the personality traits of those harboring the prejudiced attitudes. However, little is known about the personality processes (as opposed to static correlates) leading to negative attitudes and discrimination toward individuals with mental illness. The present research tested a mediational model in which negative attitudes against such people and resulting intentions to discriminate are distally rooted in just-world beliefs, which predispose people toward higher social dominance orientation, a well-known proximal personality predictor of general prejudice. Participants completed measures of behavioral intentions, attitudes toward individuals with mental illness, social dominance orientation, and belief in a just world. The proposed mediational model was supported, and an alternative causal model was not. These results illuminate the personality-process antecedents of attitudes toward individuals with mental illness and provide a foundation for research targeting interventions intended to reduce prejudice and discrimination against this population.     

At the interface of social cognition and psychometrics: Manipulating the sex of the reference class modulates sex differences in personality traits

Psychometric surveys suggest that sex differences in personality are minimal. Herein, we argue that (a) the mind is likely biased toward assessing oneself relative to same-sex others, and (b) this bias may affect the measurement of sex differences in personality. In support of this, an experiment demonstrates modulation of sex differences on the HEXACO facets by manipulating the sex of the “reference class”—the group of people subjects compare themselves to when making self-assessments on survey items. Although patterns varied across traits, sex differences were relatively small in the “unspecified” and “same-sex” reference class conditions—but substantially larger in the “opposite-sex” condition. These findings point to a same-sex comparison bias that may impact the measurement of sex differences in personality.     

Moral disengagement mechanisms in interactions of human drivers with autonomous vehicles: Validation of a new scale and relevance with personality,driving style and attitudes

The introduction of autonomous vehicles (AVs) in the road transportation systems raises questions with respect to their interactions with human drivers’, especially during the early stages. Issues such as unfamiliarity or false assumptions regarding the timid and safe behaviour of AVs could potentially result in undesirable human driver behaviours, for instance “testing” AVs or being aggressive towards them. Among other factors, morality has been determined as a source of aggressive driving behaviour. Following previous approaches on moral disengagement, the current paper argues that moral standards during interactions of human drivers with AVs could potentially blur, leading to the disengagement of self-regulation mechanisms of moral behaviour. The study investigates the impact of moral disengagement on the intention of human drivers to be aggressive towards AVs. To that end, an online survey was conducted including a newly developed survey of moral disengagement, adapted to the context of AVs. Moreover, measures of personality, driving style, attitudes towards sharing the road with AVs and perceived threats were collected. A confirmatory factor analysis provided support for the concept of moral disengagement in the context of AVs. Moreover, relationships between personality, driving style and attitudes towards sharing the road with AVs were found, via a structural equation modelling approach (SEM). The results could have implications in the future driver training and education programmes, as it might be necessary to not only focus on driving skills but also on the development of procedural skills that will improve the understanding of AVs’ capabilities and ensure safer interactions. Efforts on improving attitudes towards AVs may also be necessary for improving human driver behaviour.     

Exploring temperamental differences in infants from the USA and the Netherlands

This longitudinal study employed the Infant Behaviour Questionnaire-Revised in assessing temperamental differences between infants at 6 months (n = 114 US, 184 Dutch) and 12 months (n = 92 US, 172 Dutch) from the USA and the Netherlands. Main effects indicated that Dutch infants were rated higher on the Orienting/Regulatory Capacity (ORC) factor and fine-grained dimensions of smiling and laughter, falling reactivity, cuddliness, low-intensity pleasure, and soothability, whereas US infants received higher ratings on the Negative Affectivity factor and on dimensions of activity level, vocal reactivity, fear, frustration, and sadness. Cultural differences for ORC were more pronounced in early infancy, cultural differences for Fear were stronger in late infancy, and US infants demonstrated higher duration of orienting at 12 months only. Culture also appeared to impact the pace of consolidation of temperamental characteristics, with greater stability exhibited by US than Dutch infants in smiling and laughter and vocal reactivity.     

Instrumental lying by parents in the US and China

The practice of lying to one's children to encourage behavioral compliance was investigated among parents in the US (N = 114) and China (N = 85). The vast majority of parents (84% in the US and 98% in China) reported having lied to their children for this purpose. Within each country, the practice most frequently took the form of falsely threatening to leave a child alone in public if he or she refused to follow the parent. Crosscultural differences were seen: A larger proportion of the parents in China reported that they employed instrumental lie‐telling to promote behavioral compliance, and a larger proportion approved of this practice, as compared to the parents in the US. This difference was not seen on measures relating to the practice of lying to promote positive feelings, or on measures relating to statements about fantasy characters such as the tooth fairy. Findings are discussed with reference to sociocultural values and certain parenting‐related challenges that extend across cultures.     

Predicting counterproductive work behaviors with sub-clinical psychopathy: Beyond the Five Factor Model of personality

Organizational psychologists examining personality’s relation to work behavior have focused largely on the “normal” traits comprising the Five Factor Model (FFM). However, given the aversive nature of sub-clinical psychopathy (e.g., callous affect, impulsivity), we posit that this toxic personality profile will enhance the prediction of negative work outcomes, namely forms of counterproductive workplace behavior (CWB). Study 1 (N = 193) examined the value of sub-clinical psychopathy and the FFM in predicting intentions to engage in CWB; results support prior research indicating that both agreeableness and conscientiousness significantly correlated with CWB. In addition, sub-clinical psychopathy predicted CWB above and beyond the FFM. Study 2 (N = 360) extended the findings of Study 1 by examining interpersonally deviant behavior in a team context. While agreeableness was significantly related to interpersonal deviance in Study 2, conscientiousness was not. Results from Study 2 replicate Study 1, suggesting that sub-clinical psychopathy accounted for the majority of the explained variance in interpersonal deviance. Overall, the results support the value of using sub-clinical psychopathy to predict CWB.     

Body movements of male and female speakers and their influence on perceptions of personality

Men and women score differently on some personality traits and people’s behavior reflects who they are. Therefore, males and females could be expected to express themselves differently on a behavioral level. To test this idea we turned the public performances of speakers (20 female and 20 male) into stick figure movies. Students of the University of Vienna (n = 150) rated these movies on scales measuring the Big Five personality traits. The participants experienced difficulties in ascribing the correct sex to the stick figures. Nevertheless, stick figures representing male speakers received higher ratings for extraversion and emotional stability than stick figure animations of female speakers. In addition, gender stereotypes seemed to influence the participants’ ratings. Agreeableness, for instance, was preferably classified as female trait. In conclusion, our results suggest that body motion conveys social information, that men and women present themselves differently, and that people’s judgments are influenced by gender stereotypes.     

Cross-sectional age differences in personality: Evidence from nationally representative samples from Switzerland and the United States

Identifying reliable patterns of age differences in personality can help clarify the nature of adult personality development. Previous studies have been limited because many have relied on convenience samples. In this study, we examined age differences in personality in two nationally representative samples, one from Switzerland and one from the United States. The results indicated that Agreeableness and Conscientiousness were positively associated with age, whereas Extraversion was negatively associated with age. However, the magnitude of age differences for Extraversion was much smaller than for Agreeableness and Conscientiousness. Openness showed a more complex trend such that 30- to 34-year-olds scored lower on Openness than younger age groups, whereas older groups scored somewhere in between. Inconsistent age differences were observed for Neuroticism.     

The influence of personality on HE students’ confidence in their academic abilities

Students’ confidence in their academic abilities, measured with the Individual Learning Profile (ILP) scale, was examined in relation to their personality traits and grades. To validate the ILP, in Study 1, factor analysis of data from 3003 students extracted six factors (Reading and Writing, Hard IT, Numeracy, Time Management, Speaking, and Easy IT) with good internal reliability. Subsequently, in Study 2, 130 students completed the refined ILP, and scales measuring the Big Five, Perfectionism, Anxiety, and Self-Esteem. Between 10% and 31% of the variance in four ILP factors, but not IT skills, could be predicted by personality traits, but Self-Esteem and Anxiety were not influential. Higher conscientiousness and openness positively predicted higher confidence in reading and writing, while agreeableness and three aspects of perfectionism predicted confidence in numeracy skills. Being introverted and female were predictive of lower confidence in speaking, as were low conscientiousness and the perfectionistic desire to be organised. Conscientiousness, Extraversion, and the perfectionistic desire to be organised were strong predictors of confidence in time-management skills, which in turn predicted first-year GPA. The reliability of the ILP was examined over the course of a one-year interval.
