Psychopathic Traits in Youth: Is There Evidence for Primary and Secondary Subtypes?

The current study employed model-based cluster analysis in a sample of male adolescent offenders (n = 94) to examine subtypes based on psychopathic traits and anxiety. Using the Psychopathy Checklist: Youth Version (PCL:YV; Forth et al. 2003) and the self-report Antisocial Process Screening Device (APSD; Caputo et al. 1999), analyses identified three clusters in males that varied in the severity of psychopathic traits (low, moderate, and high) and anxiety. The high psychopathic group exhibited more negative personality traits and was judged to be at greater risk for dangerousness whereas the low psychopathic group exhibited more positive personality traits and was judged to be at lower risk for dangerousness. Implications regarding potential developmental differences between adolescent and adult psychopathy, as well as treatment considerations are discussed.     

Terror Management and Personality: Variations in the Psychological Defense Against the Awareness of Mortality

Drawing on terror management theory (TMT), we discuss the psychological motivations that shape personality at two levels: the characteristically human personality common to us all and the individual differences that distinguish some people from others. TMT posits that the motivation to protect the self against deep-rooted fears about mortality drives people to maintain meaningful, reliable conceptions of reality and positive evaluations of themselves, two broad tendencies that form the foundation of every person’s personality. We review studies showing that mortality reminders increase efforts to bolster cultural sources of meaning and self-esteem in similar ways across individuals and cultures. TMT also posits that individual differences in personality partly reflect the different sources of meaning and self-esteem that people invest in to assuage mortality fears. We review evidence that individual differences predict the degree and direction of people’s defensive responses to mortality reminders. Directions for future research are discussed.     

Not Simply “In Their Heads”: Individual Differences Associated With Victimization and Health1

Research has not examined whether victimization predicts health after controlling for personality differences associated with victimization and health. In Study 1, college students (N = 1182) completed surveys assessing victimization, health, and personality. In Study 2, college students (N = 69) participated in a short‐term longitudinal study that examined whether (a) victimization would predict health changes; (b) increases in victimization would lead to increased health problems; and (c) fall health would predict spring victimization when personality was considered. After controlling for individual differences, we found victimization predicted health outcomes (Study 1) and health problems over time (Study 2). These findings suggest the victimization–health link may occur because of physiological changes, rather than personality differences associated with victimization and health.     

Is Character Fate,or Is There Hope to Change My Personality Yet?

Different perspectives on personality development propose a range of possible degrees to which traits are free to change, from hardly at all to very much. This essay reviews the empirical evidence on just how consistent and changeable personality traits are across the life course. To gain a thorough perspective on personality trait development, we review developmental studies that focus on three different types of change: rank‐order consistency, mean level change, and individual level change. Starting in late childhood, personality traits exhibit modest levels of rank‐order consistency that increase with age. In addition personality traits show mean level changes, especially in young adulthood, that are consistent with the idea of increasing maturity. Finally, despite these general trends in personality continuity and change, there is evidence that individuals may change in ways that contradict general trends and that these individual differences in change are related to life experiences.     

Personality Traits Predict Smartphone Usage

The present study investigates to what degree individual differences can predict frequency and duration of actual behaviour, manifested in mobile application (app) usage on smartphones. In particular, this work focuses on the identification of stable associations between personality on the factor and facet level, fluid intelligence, demography and app usage in 16 distinct categories. A total of 137 subjects (87 women and 50 men), with an average age of 24 (SD = 4.72), participated in a 90‐min psychometric lab session as well as in a subsequent 60‐day data logging study in the field. Our data suggest that personality traits predict mobile application usage in several specific categories such as communication, photography, gaming, transportation and entertainment. Extraversion, conscientiousness and agreeableness are better predictors of mobile application usage than basic demographic variables in several distinct categories. Furthermore, predictive performance is slightly higher for single factor—in comparison with facet‐level personality scores. Fluid intelligence and demographics additionally show stable associations with categorical app usage. In sum, this study demonstrates how individual differences can be effectively related to actual behaviour and how this can assist in understanding the behavioural underpinnings of personality.

Cluster A Personality Symptomatology in Youth

There is an increasing recognition of the importance of studying the childhood antecedents of adult personality disorders as well as personality disorders themselves within childhood and adolescence. This has been a long neglected area of research. The two papers within this special issue of Journal of Psychopathology and Behavioral Assessment by Esterberg et al. (2010) and De Clercq et al. (2010) make significant strides toward addressing this delinquent focus of investigation. This commentary addresses three issues stimulated by these two particular studies: the distinction between personality and other mental disorders, dimensional models of classification, and openness to experience.     

Gender Differences in Personality and Interests: When,Where, and Why?

How big are gender differences in personality and interests, and how stable are these differences across cultures and over time? To answer these questions, I summarize data from two meta-analyses and three cross-cultural studies on gender differences in personality and interests. Results show that gender differences in Big Five personality traits are ‘small’ to ‘moderate,’ with the largest differences occurring for agreeableness and neuroticism (respective ds = 0.40 and 0.34; women higher than men). In contrast, gender differences on the people–things dimension of interests are ‘very large’ (d = 1.18), with women more people-oriented and less thing-oriented than men. Gender differences in personality tend to be larger in gender-egalitarian societies than in gender-inegalitarian societies, a finding that contradicts social role theory but is consistent with evolutionary, attributional, and social comparison theories. In contrast, gender differences in interests appear to be consistent across cultures and over time, a finding that suggests possible biologic influences.     

Vocational interests and Big Five traits as predictors of job instability

Although empirical research on this topic is scarce, personality traits and vocational interests have repeatedly been named as potential individual level predictors of job change. Using a long-term cohort study (N = 291), we examined RIASEC interest profiles and Big Five personality scores at the beginning of the professional career as predictors of subsequent job changes, both internal as well as external, over the next 15 years. Overall, results provide additional evidence for an individual difference perspective on job instability, although our findings vary across instability variables. Consistent with previous research, external job changes in particular related to individual differences. Specifically, scores on Investigative, Artistic, Enterprising and Conventional scales showed to be the most important interest related predictors. With regard to Big Five personality traits, strongest associations were found with Agreeableness and Openness. In addition, facet level analyses proved to be useful to further clarify linkages between personality and job instability.     

The Personality Bases of Ideology: A One-Year Longitudinal Study

ABSTRACT

The cross-lagged effects of the Big-Five personality dimensions on Social Dominance Orientation (SDO) and Right-Wing Authoritarianism (RWA) were examined over 1 year (N = 112). Consistent with the Dual Process Cognitive-Motivational Model, SDO and RWA exhibited markedly different personality bases. Low Agreeableness and unexpectedly high Extraversion predicted change in the motivational goal for group-based dominance and superiority (SDO), whereas Openness to Experience predicted change in the motivational goal for social cohesion and collective security (RWA). Neuroticism and Conscientiousness did not predict change in SDO or RWA over time. These findings extend previous cross-sectional (correlational) research and indicate that key dimensions of personality (primarily Agreeableness and Openness to Experience) are an important temporal antecedent of the group-based motivational goals underlying individual differences in prejudice.     

Gene flow by selective emigration as a possible cause for personality differences between small islands and mainland populations

Whether personality differences exist between populations is a controversial question. Even though such differences can be measured, it is still not clear whether they are due to individual phenotypic responses to the environment or whether they have a genetic influence. In a population survey we compared the personality traits of inhabitants of an Italian archipelago (the three Egadi islands; N = 622) with those of the closest mainland population (Trapani area; N = 106) and we found that personality differences between small populations can be detected. Islanders scored significantly lower on the personality traits of openness to experience and extraversion and higher on conscientiousness. We suggest that these personality trait differences could be an adaptive response to a confined socio‐environmental niche, genetically produced by a strong, non‐random gene flow in the last 20–25 generations, rather than the flexible response of islanders to environmental variables. To test this hypothesis, we compared subsets of the islander population classified by ancestry, birthplace, immigration and emigration and found that differences in extraversion can be accounted for by gene flow, while openness to experience and conscientiousness can also be accounted for by some gene–environment interactions. We propose a Personality Gene Flow hypothesis suggesting that, in small isolated communities, whenever there is strong, non‐random emigration, paired with weak and random immigration, we can expect rapid genetic personality change within the population.

Mapping the Landscape of Personality in Childhood and Adolescence

From infancy, children vary in their typical emotions and behaviors, and by the middle of childhood, children have richly differentiated personalities. In this paper, I review the personality differences that youths exhibit from early childhood through adolescence, using a three-part taxonomy developed by (McAdams, D. P., & Pals, J. L. American Psychologist, 2006; 61, 204–217). First, children exhibit a dispositional signature, including first temperament traits and later the Big Five personality traits, which show some consistency across situations and over time. Second, youths display characteristic adaptations that are more specific to particular life contexts; these include mental representations, strategies, and goals. Third, adolescents form personal narratives, stories about their lives that reflect and shape their identities. I describe the differences youths exhibit in these three domains and situate these differences in the context of overall development in childhood and adolescence. New work on youths’ personalities can serve as the foundation for future lifespan perspectives on personality development.     

Non-monotonicity and Informal Reasoning: Comment on Ferguson (2003)

In this paper, it is argued that Ferguson’s (2003, Argumentation 17, 335–346) recent proposal to reconcile monotonic logic with defeasibility has three counterintuitive consequences. First, the conclusions that can be derived from his new rule of inference are vacuous, a point that as already made against default logics when there are conflicting defaults. Second, his proposal requires a procedural “hack” to the break the symmetry between the disjuncts of the tautological conclusions to which his proposal leads. Third, Ferguson’s proposal amounts to arguing that all everyday inferences are sound by definition. It is concluded that the informal logic response to defeasibility, that an account of the context in which inferences are sound or unsound is required, still stands. It is also observed that another possible response is given by Bayesian probability theory (Oaksford and Chater, in press, Bayesian Rationality: The Probabilistic Approach to Human Reasoning, Oxford University Press, Oxford, UK; Hahn and Oaksford, in press, Synthese).     

Personality predicts prospective memory task performance: an adult lifespan study

Do interindividual differences in prospective memory task performance reflect individual differences in personality and lifestyle? Do the cognitive abilities known to change with age retain their power to predict episodic prospective memory task performance after controlling for personality and lifestyle variables, and do personality and lifestyle variables offer predictive power apart from that provided by cognitive ability measures? To answer these questions, we conducted a study with community‐living healthy individuals (n= 141) between 18 and 81 years of age. They completed three different episodic prospective memory tasks – two laboratory tasks and one field task – as well as various measures of personality, lifestyle, and cognitive ability. The results indicated that personality and lifestyle reliably predicted who will succeed and who will fail on all three episodic prospective memory tasks. Conscientiousness predicted performance on two of the prospective memory tasks; socially prescribed perfectionism and neuroticism each predicted performance on one of the prospective memory tasks. Cognitive ability predicted performance on one of the laboratory prospective memory tasks but not on the other two prospective memory tasks. After we controlled for individual differences in personality and lifestyle variables, cognitive ability was no longer able to predict performance on the laboratory prospective memory task. By contrast, controlling for cognitive ability had no influence on the predictive power of the personality and lifestyle variables.     

Emergent Issues in Assessing Personality Pathology: Illustrations from Two Studies of Adolescent Personality and Related Pathology

As illustrated by two articles that each investigate personality pathology and its correlates in adolescents—Aelterman et al. (2010) on obsessive-compulsive personality disorder (OCPD) from a dimensional personality perspective, and Barry and Wallace (2010) on indicators of pathological and normative development of youth narcissism—this commentary discusses four important assessment issues that have become more salient as the field considers a shift, through proposed changes in the DSM, to an approach that incorporates trait dimensions as an important aspect of diagnosis: (1) the importance of using multiple information sources for valid personality/ PD assessment; (2) relations of personality traits to (mal)adaptivity in general and also with regard to (3) trait uni- versus bi-polarity; and (4) whether personality types have incremental predictive value beyond their component personality traits and related pathology. The article also discusses why research on childhood and adolescent personality/ PD is important in addressing these issues.     

Personality accounts for stable preferences and expectations across a range of simple games

Behaviour on even simple experimental games shows considerable individual differences, but previous attempts to link these preferences to stable personality traits have had mixed results. Here we address three limitations of earlier studies, namely: (1) uncertainties concerning the reliability of preferences; (2) use of personality instruments with limited cross-study comparability; and (3) confounds where more than one psychological motive can lead to a particular choice. Sixty-seven participants completed 12 distinct real-money games twice over a two-week interval along with 6 measures concerning their expectations about other players’ choices. Personality was measured using the full NEO-PI-R. Choices were highly stable across time (r = .84). Moreover, choices on the 12 games and 6 expectations reflected a single underlying dimension of “prosocial orientation”, measuring concern for the payoffs received by other players. Scores on the prosocial orientation dimension were related to personality, with openness, (low) neuroticism, and (low) extraversion retained as significant predictors.     

Persistent pursuit of need-satisfying goals leads to increased happiness: A 6-month experimental longitudinal study

University-based community members (N = 181) participated in a four-wave, 6-month longitudinal experiment designed to increase treatment participants’ happiness levels. Participants were randomly assigned to set goals either to improve their life circumstances (comparison condition) or to increase their feelings of autonomy, competence, or relatedness in life (treatment conditions). We hypothesized that sustained gains in happiness would be observed only in the three treatment conditions, and that even these gains would last only when there was continuing goal engagement. Results supported these predictions and the sustainable happiness model on which they were based (Lyubomirsky et al. in Rev Gen Psychol 9:111–131, 2005). Furthermore, participants with initial positive attitudes regarding happiness change obtained larger benefits. We conclude that maintained happiness gains are possible, but that they require both “a will and a proper way” (Lyubomirsky et al. in Becoming happier takes both a will and a proper way: two experimental longitudinal interventions to boost well-being, 2009).     

The thrill of loving a dominant partner: Relationships between preference for a dominant mate,sensation seeking,and trait anxiety

This study investigates whether particular personality traits predict the desire to choose a dominant partner. Specifically examined are the traits of sensation seeking and trait anxiety as predictors of the preference for a dominant female/male partner. Sixty‐eight men and 104 women (N = 172) participated in an online survey. Individuals who avoid boredom and seek out exciting social activities have a stronger desire for a dominant partner. For female participants, we detected experience seeking and trait anxiety as additional factors associated with the preference for a dominant partner. Women higher in trait anxiety and lower in experience seeking have a higher preference for a dominant man. Gender differences are interpreted with regard to sexual selection theory and individual differences with respect to the theory of assortative mating.     

Progress Toward Understanding the Structure and Determinants of Job Performance: A focus on task and citizenship performance

Job performance criterion models have become more popular and more often investigated. The current research adds to this literature by testing performance models focusing on ability and personality predictors of task and citizenship job performance. Air traffic controllers (N = 928) completed cognitive ability and personality predictor measures, were administered a performance test assessing two possible mediators, and were evaluated using supervisor and peer ratings of two task performance, one citizenship performance, and an overall performance dimension. Path analyses largely confirmed that ability predicts primarily task performance and personality predicts primarily citizenship performance. The mediation related to task knowledge and skill on the task performance side was confirmed, and the overall fit of the performance models was quite good. Discussion focuses on how the present research furthers progress toward mapping relations among individual differences and individual performance constructs, beyond using overall performance as the endogenous performance variable.     

Happiness and Unhappiness in the Developing World: Life Satisfaction Among Sex Workers, Dump-Dwellers, Urban Poor, and Rural Peasants in Nicaragua

Little in-depth research exists on subjective well-being (SWB) in the developing world, especially among the poor and extremely poor. Biswas-Diener and Diener (Soc Indic Res 55:329–352, 2001) employed a study design in the slums of Calcutta, India to address this gap in SWB research. They found slightly negative global SWB but slightly positive domain specific satisfaction in their sample. The current study employs the same paradigm and investigates the SWB of female sex workers, city dump dwellers, and urban and rural poor in Nicaragua, Central America. The current study was able to replicate the Biswas-Diener and Diener (Soc Indic Res 55:329–352, 2001) finding of slightly negative SWB for marginalized urban groups. In addition, an overall model for predicting SWB was constructed using personality dispositions, objective income, social support, and social rootedness as predictors. Social support and objective income were the only significant predictors in the model but more zero order relations existed. Additionally, this study contrasted urban poor versus rural poor and found no significant SWB differences.     

Individual Differences in Religion and Spirituality: An Issue of Personality Traits and/or Values

Personality, in terms of both strict personality traits (five factors) and their cultural adaptations (e.g., values), has systematically been found to predict religion. This article focuses on three issues that still remain unclear: predictiveness of personality facets versus the five factors; predictiveness of values versus personality; and similarities and differences between religiosity and spirituality in their associations with personality and values. We administered the NEO-PI-R, the Schwartz Value Survey, and religious measures to Spanish students (N = 256). The personality facets provided additional and subtler information than the five factors on individual differences in religion and spirituality. When the overlap between personality and values was controlled for, values were almost unique predictors of these differences. Spirituality shared with religion both a prosocial tendency (with even some intensification) and conscientiousness, but not the emphasis on conservation versus openness to change and to experience.
