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.     

Personality predicts academic performance: Evidence from two longitudinal university samples

To what extent and which personality traits predict academic performance was investigated in two longitudinal studies of two British university samples. Academic performance was assessed throughout a three years period and via multiple criteria (e.g., exams and final-year project). In addition several indicators of academic behaviour, e.g., absenteeism, essay writing, tutors’ exam predictions, were also examined with regard to both academic performance and personality traits. In sample 1 (N=70), the Big Five personality factors (Costa & McCrae, 1992)—particularly Neuroticism and Conscientiousness—were found to predict overall final exam marks over and above several academic predictors, accounting for more than 10% of unique variance in overall exam marks. Results suggest that Neuroticism may impair academic performance, while Conscientiousness may lead to higher academic achievement. In sample 2 (N=75) the EPQ-R (Eysenck & Eysenck, 1985) was used as the personality measure and results showed the three superfactors were the most powerful predictor of academic performance, accounting for nearly 17% of unique variance in overall exam results. It is demonstrated that (like Neuroctisim) Psychoticism could limit academic success. The present results provide evidence supporting the inclusion of well-established personality measures in academic selection procedures, and run counter to the traditional view of ability measures as the exclusive psychometric correlate of academic performance.     

Personality development in old age relates to physical health and cognitive performance: Evidence from the Berlin Aging Study II

We examine how late-life personality development relates to overall morbidity as well as specific performance-based indicators of physical and cognitive functioning in 1,232 older adults in the Berlin Aging Study II (aged 65–88 years). Latent growth models indicated that, on average, neuroticism and conscientiousness decline over time, whereas extraversion and openness increase and agreeableness remains stable. Higher morbidity and worse grip strength were associated with higher neuroticism. Lower grip strength was further associated with lower openness, attenuated increases in extraversion, decreases in agreeableness and accelerated declines in conscientiousness. Moreover, those with poor perceptual speed reported higher neuroticism and lower conscientiousness. We also found age- and gender-differential associations between physical health and cognitive performance with levels of and changes in personality.     

Big-Five personality and political orientation: Results from four panel studies with representative German samples

The aim of this brief report was to replicate the meta-analytic findings concerning the relationship between Big-Five personality and political orientation reported in Sibley, Osborne, and Duckitt (2012) in a sample of N = 29,015 participants from four panels involving representative German samples. We replicated the expected significant correlations for Openness to Experience (r = −0.07; 95% CI [−0.10, −0.05]) and Conscientiousness (r = 0.06, 95% CI [0.05, 0.08]), but the effect sizes were smaller than in Sibley et al. (2012). We also found significant correlations for Agreeableness (r = −0.04; 95% CI [−0.05, −0.03]) and Neuroticism (r = −0.04; 95% CI [−0.06, −0.02]), indicating small but significant relations of additional Big-Five dimensions on political orientation.     

Personality as a Source of Individual Differences in Cognition among Older African Americans

Previous research suggests that demographic factors are important correlates of cognitive functioning in African Americans; however, less attention has been given to the influence of personality. The present study explored how dimensions and facets of personality predicted individual variability in cognition in a sample of older African Americans from the Baltimore Study of Black Aging. Cognition was assessed by verbal learning and attention/working memory measures. Personality was measured by the NEO Personality Inventory-Revised. Linear regressions controlling for demographic factors showed that Neuroticism, Openness, and Agreeableness were significant regression predictors of cognitive performance. Individual facets of all five personality dimensions were also associated with cognitive performance. These findings suggest personality is important in understanding variability in cognition among older African Americans.     

Personality and the four faces of positive affect: A multitrait-multimethod analysis using self- and peer-report

The present study investigates the relationship between personality and positive affects (contentment, love, interest, and joy). Using multitrait-multimethod analysis and structural equation modeling procedures with self- and peer-report, the authors demonstrated the importance of differentiating between the positive affects. A multidimensional model fitted better than a general-factor model. Concerning the personality–affect relationship, the strongest relations were found between extraversion and both joy and love, agreeableness and love, openness to experiences and interest, and neuroticism and contentment. Thus, results suggest that it is insufficient to concentrate solely on extraversion when investigating the personality–positive affect relationship.     

Personality and social attitudes: Evidence for positive-approach motivation

Extensive research has linked general personality factors to social attitudes, but there has been comparatively little work on the roles played by specific approach-avoidance personality factors, especially positive-approach ones. Here we relate such factors to the two main clusters of social attitudes (Right-Wing Authoritarianism, RWA; and Social Dominance Orientation, SDO), and related cognitive constructs (Need for Cognition and Need for Closure). Results revealed: (a) positive-approach motivation is consistently related to both RWA and SDO, with little contribution from negative-avoidance motivation; and (b) negative-avoidance motivation played a part in Need for Cognition (negatively related) and Need for Closure (positively related). These data challenge previous theorizing concerning the role of fear/anxiety in social attitude formation and prejudice more generally. We conclude that, to a larger extent than previously thought, approach-related personality factors underpin the positive reinforcement of social attitudes and prejudice. Our results may help to account for the failure of programmes designed to reduce prejudice which have been based on the reduction of negative emotion and motivation.     

The General Factor of Personality in selection and assessment samples

In two large samples (N₁ = 44,971, N₂ = 7793) we tested the General Factor of Personality (GFP) in the Big Five, measured during selection and assessment. A GFP could clearly be identified in the data, explaining approximately 50% of the Big Five variance. We found indications for socially desirable response tendencies in a subgroup that was tested for selection purposes. Yet, this tendency did not affect the personality factor structure or the GFP characteristics. Moreover, in the selection sample, the GFP was moderately related to the Overall Assessment Rating. The findings confirm the GFP in an applied setting and support the idea that the GFP does not merely reflect methodological artifacts but is substantive.     

Evaluating the Evidence for the General Factor of Personality across Multiple Inventories

A general factor of personality (GFP) has been proposed as the apex of a personality trait hierarchy that explains covariance among the lower-order factors measured by various personality inventories. In this study we evaluated the GFP hypothesis across several personality inventories, unlike most previous research in which the GFP has been derived from individual instruments in isolation. Exploratory analyses did not produce substantial evidence for the existence of a single cross-instrument higher-order factor of factors and efforts to specify a range of GFP-inspired models in a confirmatory framework led to significant estimation difficulties and poor fit to the data. Overall these results fail to support a common GFP that is positioned at the top of a personality trait hierarchy.     

Evidence for the role of the General Factor of Personality (GFP) in enculturation: The GFP and self-construal in Japanese and American samples

Data from Midlife in the United States (MIDUS) studies, one with American participants and one with Japanese participants, were used to test the hypothesis that the General Factor of Personality (GFP) is positively associated with enculturation. To this end, the relationships between the GFP and independent self-construal and interdependent self-construal were examined. Consistent with the hypothesis, the results showed that an independent self-construal was more closely associated with the GFP in the American sample.     

Personality links to anger: Evidence for trait interaction and differentiation across expression style

Anger is a commonly experienced emotion, although marked individual differences in the expression of anger are observed. Basic dimensions of personality (e.g., Big Five traits) have been shown to predict the experience of trait anger; however, little work has addressed the personality correlates of broader conceptualisations of trait anger (e.g., inward or outward expressions). Additionally, while some recent work has suggested that basic personality traits may show interactive influences on anger expression this work has yet to be independently confirmed. In a large sample of adults we examined, firstly, how Big Five traits associated with several components of anger as measured by the State-Trait Anger Expression Inventory. Secondly, we examined whether these associations were further qualified by interactions between Big Five traits. Results indicated neuroticism and, to a lesser extent, (low) agreeableness, were the traits most associated with components of trait anger. Conscientiousness and extraversion were also noted to show links to more focal components of anger. Moderation was observed: conscientiousness moderated neuroticism’s relationship with anger control, and agreeableness and conscientiousness, in a three-way interaction, moderated neuroticism’s relationship with trait anger. These observations help to further clarify the role of Big Five personality traits as a foundation for the experiences of anger, demonstrating how anger style varies across personality configuration.     

Personality and space: Introversion and seclusion

Two studies examined whether extraversion was associated with different types of geographical preferences. During the first study, participants were given free time and directed to return to the designated location after 45 min, where they completed a questionnaire. This study found that extraversion is inversely associated with the seclusion level of the space in which participants preferred to spend this free time. In Study 2 participants in various university campus locations completed a personality questionnaire. Extraversion was positively associated with the openness of the location, and inversely associated with the distance from the center of the campus. These findings suggest that extraversion is systematically associated with different space preferences and use.

Evidence for the role of personality in the cognitive performance of older male drivers

ObjectivesThis study aimed to examine whether in older male drivers the level of information processing under increasing cognitive workload varies with the level of personality traits.MethodThe study involved 60 male, active drivers aged between 65 and 81 (M = 71, SD = 4.4). During passive driving they performed central (a test in the n-back scheme, in three cognitive workload levels) and peripheral (memorizing objects characteristic for road traffic) tasks presented simultaneously in the central and peripheral visual fields. A wide-angle high-fidelity collimated visual system was used to display visual stimuli. In the central task, the reaction time and its correctness were measured, while the peripheral task measured the number of memorized objects. The EPQ-R questionnaire was used to assess personality traits, and the memory functions were assessed using the MMSE test.ResultsAs the central task-induced cognitive workload increases, the performance of both central and peripheral tasks deteriorates. These tasks were performed less accurately by drivers with a higher level of psychoticism than those with a lower level of this trait. This dependency related to all levels of cognitive workload. In contrast, the drivers with a higher level of neuroticism showed a lower level of performance of the peripheral task than those with a low level of this trait. This dependency concerned only the central task with a medium cognitive workload.ConclusionThe level of personality traits, especially the ones related to the emotional sphere, contributed to the decrease in the effectiveness of action (longer reaction time, increase in the number of errors, decrease in the number of memorized objects) in the conditions of increasing cognitive workload. A higher level of neuroticism and psychoticism can be conducive to making errors on the road. This applies especially to situations that pose high demands on the driver’s cognitive system.     

Personality in the age of industry: Structure,heritability, and correlates of personality in middle childhood from the perspective of parents,teachers, and children

Middle childhood is a crucial juncture in the lifespan where children work toward achieving a sense of competence foundational for future development. However, middle childhood has historically been underrepresented in the personality literature. The current study provides a comprehensive examination of personality in middle childhood using a large (N = 2510), longitudinal sample of 10- to 12-year-old twins. The structure, heritability, and correlates of personality in this period were investigated using personality ratings of parents, teachers, and children. Results showed that personality in middle childhood has a coherent structure, is heritable, and is relevant for developmentally salient outcomes such as externalizing behavior, substance use, and academic engagement. Results emphasize the importance of investigating personality in middle childhood across multiple informants.     

Personality Trait Development and Social Investment in Work

A longitudinal study of employed individuals was used to test the relationship between social investment at work—the act of cognitively and emotionally committing to one’s job—and longitudinal and cross-sectional personality trait development. Participants provided ratings of personality traits and social investment at work at two time-points, separated by approximately 3 years. Data were analyzed using latent change models. Cross-sectional results showed that extraversion, agreeableness, conscientiousness, and emotional stability were related to social investment at work. Additionally, a positive association was found between longitudinal change in social investment in work and change in personality traits—especially conscientiousness. Finally, the correlated changes in social investment and personality traits were invariant across age groups, suggesting that personality traits remain malleable across the lifespan.     

Cigarette smoking and personality change across adulthood: Findings from five longitudinal samples

Personality traits are related to cigarette smoking. However, little is known about the link between smoking and change in personality. Therefore, the present study examined whether current cigarette smoking and smoking cessation are associated with personality change across adulthood. Participants (n = 15,572) aged from 20 to 92 years were drawn from five longitudinal cohorts with follow-ups that ranged from 4 to 20 years. Compared to non-smokers, current smokers were more likely to increase on neuroticism and to decline on extraversion, openness, agreeableness and conscientiousness over time. Compared to the persistent smokers, those who quit had a steeper decline in agreeableness. Cigarette smoking is related to detrimental personality changes across adulthood, and the pattern was not improved by smoking cessation.     

Personality and Paranormal Belief: A Study Among Adolescents

A sample of 279 13- to 16-year-old adolescents completed the Short-form Revised Junior Eysenck Personality Questionnaire (JEPQR-S) and a six-item Index of Paranormal Belief. The data demonstrate that neuroticism is fundamental to individual differences in paranormal belief, while paranormal belief is independent of extraversion and psychoticism.     

Personality and geography: Introverts prefer mountains

In five studies, we tested the link between personality and geography. We found that mountain-lovers were more introverted than ocean-lovers (Study 1). People preferred the ocean over mountains when they wanted to socialize with others, but they preferred the mountains and the ocean equally when they wanted to decompress alone (Study 2). In Study 3, we replicated the introversion–extraversion differences using pictures of mountains and oceans. Furthermore, this difference was explained in part by extraverts’ perception that it would take more work to have fun in the mountains than in the ocean. Extending the first three studies to non-students, we found that residents of mountainous U.S. states were more introverted than residents of flat states (Study 4). In Study 5, we tested the link between introversion and the mountains experimentally by sending participants to a flat, open area or a secluded, wooded area. The terrain did not make people more introverted, but introverts were happier in the secluded area than in the flat/open area, which is consistent with the person–environment fit hypothesis.     

Personality and Intelligence in Business People: A Study of Two Personality and Two Intelligence Measures

This study examined the overlap and correlations among two well-known personality measures (NEO-PI–R; Myers-Briggs Type Indicator, MBTI) and two widely used intelligence tests (the Graduate Management Assessment (GMA), Watson-Glaser Critical Thinking Appraisal (WGCTA)). The GMA measures both fluid intelligence (Gf) and crystallized intelligence (Gc), whereas WGCTA mainly assess Gc. A total of over 3,500 participants completed the four measures in a middle management assessment event. Correlational analysis showed that Extraversion on the MBTI tended to be associated with Openness and Stability on the NEO. Intuition was associated with Openness and Introversion. Feeling types tended to be both Agreeable and Neurotic while perceiving types were high on Openness but low on Agreeableness. The NEO Big Five factor of Openness was most consistently and significantly associated with both measures of intelligence (r = .09 to r =.12). Results from the MBTI showed that Intuition and Perceiving scores were positively and significantly associated with both intelligence test scores which were intercorrelated (r = .38). Regressional analysis showed that personality traits are logically and coherently related to intelligence test scores. Implications for selection and assessment are considered.
