Do you see my growth? Two longitudinal studies on personality development from childhood to young adulthood from multiple perspectives

Personality developmental studies typically rely on single reporter data, while multi-informant studies are rare. In two longitudinal studies, the present investigation examined inter-judge differences in the development of the Big Five personality traits from childhood to young adulthood. Study 1 investigated personality development as judged by the self and parents from age 12 to 17 to 29 (N = 186). Study 2 investigated personality development annually from age 12 to 18 as judged by the self, and both parents and siblings (N = 574). Results showed personality maturation from childhood to young adulthood with disruptions during adolescence. Only parent-reports indicated maturation in adolescents’ negative affectivity (decreases in N), while self-reports indicated maturation in self-regulatory traits (increases in A and C).     

Dorian Gray without his portrait: Psychological,social, and physical health costs associated with the Dark Triad

We examined how the Dark Triad (i.e., narcissism, psychopathy, and Machiavellianism) traits—as different social strategies—were associated with various health outcomes. In samples of American undergraduates (N = 1389), Australian high school students (N = 2023), and British undergraduates (N = 280), we examined the physical, social, and psychological costs associated with the Dark Triad traits. Narcissism was linked to few mental and physical ailments, suggesting it may provide a social buffer from negative health outcomes (Studies 1 and 2). Psychopathy (Studies 1 and 2) and Machiavellianism (Study 2) were linked to a number of psychological and physical health conditions. In addition, psychopathy was related to diminished life expectancy, whereas narcissism was related to enhanced life expectancy (Study 3). Our findings provide evidence that each of these personality traits is linked to various psychosocial tradeoffs and different methods of coping with stress and adaptive problems.     

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.     

The young and the restless: Examining the relationships between age,emerging adulthood variables,and the Dark Triad

The Dark Triad is a set of correlated personality variables (i.e., narcissism, psychopathy, and Machiavellianism) that are related to myriad behaviors. Myriad studies have been conducted to test the relations between the Dark Triad and other personality variables (e.g., the Big 5); however, the developmental correlates have been understudied. In the current study, we examined how markers of emerging adulthood and age predict the Dark Triad traits using a cross-sectional design. Participants (N = 442) of varying ages (M age = 32.99, range = 18–74) completed Dark Triad measures and a validated questionnaire used to assess the degree to which participants believe they have successfully navigated through various facets of emerging adulthood. Emerging adulthood facets (e.g., negativity, other-focused, and feeling in-between) correlated with several Dark Triad traits. Additionally, several emerging adulthood facets mediated the relation between age and the Dark Triad traits; i.e., older participants were lower on the Dark Triad traits because of the successful transition through emerging adulthood. Results are discussed in terms of the Theory of Emerging Adulthood (Arnett, 2000).     

Mirror,mirror, on the wall,who is the most masculine of them all? The Dark Triad,masculinity, and women’s mate choice

Although the Dark Triad of personality (i.e., Machiavellianism, narcissism, and psychopathy) has been researched widely, few studies have looked at women’s preferences for men who are high and low in Dark Triad. Further, it is not clear what the relationships between the Dark Triad and facial masculinity are. We investigated female preference for computer manipulated Dark Triad male faces in two on-line studies (Study 1: n = 125; Study 2: n = 1633). We found that women rated the high psychopathy and narcissistic faces the most masculine (Study 1). We also found that women showed a low preference for the high morphs in both long and short term relationships, and that preference for masculinity was correlated with a preference for narcissism (Study 2). We discuss the results in terms of male and female mating strategies.     

Adversity in adolescence predicts personality trait change from childhood to adulthood

This study examined whether cumulative adversity in adolescence predicted changes in the Big Five traits from childhood to adulthood in the Project Competence Longitudinal Study sample (N = 205) followed from childhood (age 10) through adolescence into adulthood (age 30). Personality traits were measured in childhood through multiple methods and in adulthood by self-report. Cumulative adversity, assessed in adolescence, differentiated independent adversity (likely unrelated to participants’ behavior) from dependent adversity (resulting from participants’ own behavior). Participants’ personality traits were modestly stable over 20 years, although Openness showed greater stability. Independent and dependent adversity predicted increases in Negative Emotionality/Neuroticism, and dependent adversity predicted decreases in Constraint/Conscientiousness and Agreeableness from childhood to adulthood, suggesting that cumulative adversity shapes personality development in young people.     

Personality self-concept affects processing of trait adjectives in the self-reference memory paradigm

We combined personality, social cognitive, and cognitive paradigms for researching the self. Specifically, we examined whether personality trait assessments are associated with variation in the cognitive processes that produce the self-reference effect in memory. We found that self-reported, but not indirectly assessed, trait orderliness (Study 1; N = 98) and openness (Study 2; N = 92) were associated with slower free recall when corresponding trait adjectives were self-referenced, but not when adjectives were encoded in control tasks. The slower recall showed mixed predictive validity. Results suggest that personality congruent adjectives elicit more elaborative processing in the form of propositions that arise during self-reference, which counter-intuitively slows recall in a manner consistent with random search memory models and cue overload theory.     

A genetic variant (COMT) coding dopaminergic activity predicts personality traits in healthy elderly

Association studies between the NEO five factor personality inventory and COMT rs4680 have focused on young adults and the results have been inconsistent. However, personality and cortical changes with age may put older adults in a more sensitive range for detecting a relationship. The present study examined associations of COMT rs4680 and personality in older adults.Genetic association analyses were carried out between the NEO and the targeted COMT rs4680 in a large, well-characterized sample of healthy, cognitively normal older adults (N = 616, mean age = 69.26 years).Three significant associations were found: participants with GG genotype showed lower mean scores on Neuroticism (p = 0.039) and higher scores on Agreeableness (p = 0.020) and Conscientiousness (p = 0.006) than participants with AA or AG genotypes.These results suggest that older adults with higher COMT enzymatic activity (GG), therefore lower dopamine level, have lower Neuroticism scores, and higher Agreeableness and Conscientiousness scores. This is consistent with a recent model of phasic and tonic dopamine release suggesting that even though GG genotype is associated with lower tonic dopamine release, the phasic release of dopamine might be optimal for a more adaptive personality profile.     

Predictors of volitional personality change in younger and older adults: Response surface analyses signify the complementary perspectives of the self and knowledgeable others

Goals to change personality traits have been linked to self-rated Big Five traits. Extending previous research, we investigated the associations between change goals and diverse personality characteristics (e.g., self-esteem), other-rated Big Five traits, and self-other agreement in an age-heterogeneous sample (N = 378). Results replicated previous associations of change goals with age and self-rated traits. Additionally, change goals were stronger when others rated a person’s traits as low and when self-other agreement about traits was greater for extraversion, agreeableness, and conscientiousness. Associations of additional personality characteristics with change goals diminished when we controlled for the Big Five traits. We conclude that goals to change personality traits primarily reflect the perspective of the self and, for some traits, of knowledgeable others.     

Age-progressed images may harm recognition of missing children by increasing the number of plausible targets

Age progression, often used to help find missing children, is a technique whereby an outdated photograph of an individual is used to generate an updated image of that individual. Despite its importance, few empirical psychological studies have tested the utility of age progression. The current studies had two purposes: (1) to empirically test the effectiveness of a computerized age-progression system (APRILage); and (2) to examine how the presentation of an age-progressed image changes observers’ decision-making strategies. Presenting participants with an age-progressed image in addition to an outdated image resulted in fewer target recognitions and more mistaken non-target ‘recognitions’ (Study 1; N = 135), led participants to assign fewer confidence points to the actual target and more confidence points to non-targets (Study 2; N = 231), and increased, rather than decreased, the number of plausible targets (Study 3; N = 88). Results are explained within a multidimensional face-space conceptualization of facial recognition.     

Does Worrying Mean Caring Too Much? Interpersonal Prototypicality of Dimensional Worry Controlling for Social Anxiety and Depressive Symptoms

Worry, social anxiety, and depressive symptoms are dimensions that have each been linked to heterogeneous problems in interpersonal functioning. However, the relationships between these symptoms and interpersonal difficulties remain unclear given that most studies have examined diagnostic categories, not accounted for symptoms’ shared variability due to general distress, and investigated only interpersonal problems (neglecting interpersonal traits, interpersonal goals, social behavior in daily life, and reports of significant others). To address these issues, students (Study 1; N = 282) endorsed symptoms and interpersonal circumplex measures of traits and problems, as well as event-contingent social behaviors during one week of naturalistic daily interactions (N = 184; 7,036 records). Additionally, depressed and anxious patients (N = 47) reported symptoms and interpersonal goals in a dyadic relationship, and significant others rated patients’ interpersonal goals and impact (Study 2). We derived hypotheses about prototypical interpersonal features from theories about the functions of particular symptoms and social behaviors. As expected, worry was uniquely associated with prototypically affiliative tendencies across all self-report measures in both samples, but predicted impacting significant others in unaffiliative ways. As also hypothesized, social anxiety was uniquely and prototypically associated with low dominance across measures, and general distress was associated with cold-submissive tendencies. Findings for depressive symptoms provided less consistent evidence for unique prototypical interpersonal features. Overall, results suggest the importance of multimethod assessment and accounting for general distress in interpersonal models of worry, social anxiety, and depressive symptoms.     

Risk-taking and impulsive personality traits in proficient downhill sports enthusiasts

Although past studies have examined how personality traits may motivate participation in high-risk sports, few previous studies have examined impulsive personality correlates with risk-taking within a group of sports enthusiasts. We examined relationships between measures of personality and risk-taking on the slopes as measured by a sport-specific Sensation Seeking Scale in a sample of proficient-level skiers and snowboarders (N = 123, 61% male). Significant correlations were found between risk-taking and multiple traits including Reward Sensitivity, Punishment Sensitivity, and Sensation Seeking, implying that some traits that motivate participation in high-risk sports also lead to more risky behavior while participating in said sports. Rash Impulsivity, though not found to distinguish participants from non-participants in previous studies, did correlate with risk-taking behavior on the slopes. The results of this study show that while some aspects of impulsive personality may motivate risky sport participation, other traits may be related to risky behavior once engaged in the sport.     

Goals and plans for Big Five personality trait change in young adults

Four studies were conducted on young adults’ goals and plans to change personality traits. In Study 1, a new trait change goal assessment tool, the BF-TGI, found Neuroticism to be the most frequently cited trait for a change goal. In Study 2, data was gathered from the UK, Iran and China. Iran showed a higher prevalence of normative change goals than the UK and China. Study 3 investigated plans to change traits. Extraversion and Conscientiousness plans were more specific than for the other traits. Study 4 investigated whether goals and plans to change predict change over 12 months, and found that goals and plans to change Conscientiousness and Neuroticism predicted change in the opposite direction to the goal.     

Cognitive abilities and personality traits in old age across four years: More stability than change

The current study (N = 236) examined stability and change of six cognitive abilities and three personality traits in old age (M = 74.12 years, SD = 4.40) over four years. Furthermore, we investigated whether levels of one domain were related to the other domain (and vice versa) four years later. The results showed a mean–level decline for processing speed and a mean–level increase for neuroticism. Cross–lagged effects indicated that reasoning was related to openness and conscientiousness was related to verbal knowledge four years later. In general, few and weak associations between the two domains were found. The findings showed that the development of cognitive abilities and personality traits in old age is marked more by stability than by change.     

Conceptualizing the Dark Triad of personality: Links to Social Symptomatology

The current study examines the conceptualization of the sub-clinical Dark Triad personality traits (Psychopathy, Machiavellianism, and Narcissism; Paulhus & Williams, 2002) by relating them to normal and abnormal personality. Factor analyses using two samples (N₁ = 232, N₂ = 198) showed the Dark Triad traits clearly aggregated with each other, with Social Symptomatology, and with low agreeableness. More detailed analyses found that sub-clinical psychopathy is related to a core of socially malevolent traits and items that reflect self-reported deviant socialization in childhood, alienation from others, interpersonal problems, and impulsivity. For Machiavellianism, these relationships were apparent at the item level but not at the trait level. Narcissism, however, appears to be a more distinct construct that relates to aspects of psychopathology other than Social Symptomatology. Overall, results indicate that the Dark Triad is best conceptualized as a form of disordered personality, with links to low agreeableness.     

Therapy experience in naturalistic observational studies is associated with negative changes in personality

Recent research has shown that personality traits change as a result of clinical therapy, although evidence for this effect is derived from efficacy studies that reflect relatively controlled experimental designs. Little is known about how therapy in real world contexts affects change in personality. In two longitudinal studies (N’s = 1270 and 5217), the present research examined whether personality trait change was associated with therapy experience. Propensity score matching was used to compare trajectories of personality trait change in individuals with and without therapy experiences. Overall, therapy experiences were associated with significant increases in undesirable traits and markers (e.g., chronic stress, depression, neuroticism), and significant decreases in desirable traits (e.g., self-esteem, conscientiousness).     

Personality styles in a non-clinical sample: The role of emotion dysregulation and impulsivity

Theories of personality and personality disorders are increasingly considering the centrality of emotion regulation and its dimensions. Impulsivity as well is recognized as a personality trait underlying diverse symptom presentations. Although research in this field has mainly regarded borderline personality disorder, recent studies supported the association of both emotion dysregulation and impulsivity with personality styles across all clusters. In the present study, we sought to extend extant research by investigating the joint contribution of selected difficulties in emotion regulation and impulsivity to traits of four personality styles in a community sample (N = 399, mean age = 37.91, 56.6% males). In particular, we focused on depressive, masochistic, passive-aggressive and sadistic personality styles. Multiple regression analyses showed the unique association of several domains of emotion dysregulation with all personality styles examined. Nonacceptance of emotional response was significantly and positively related with scores of all personality styles. Lack of emotional awareness was also characteristic of different styles. Beyond these similarities, distinct patterns were able to distinguish between externalizing (sadistic and passive-aggressive), and internalizing (depressive and masochistic) traits. Beyond the role of emotion dysregulation, trait impulsivity was also related to masochistic, passive-aggressive, and sadistic traits, independently explaining a significant amount of additional variance.     

Personality traits and affective states: Relationships with and without affect induction

Substantial evidence shows that extraversion is related to positive affect (PA) and neuroticism is related to negative affect (NA), and there are several possible explanations for these relationships. The current paper replicates these findings and examines relationships between the other Big Five traits with general positive and negative states (N = 257). Agreeableness was negatively related to NA, while conscientiousness and openness were positively related to PA. Next, affect was induced and extraversion and conscientiousness predicted changes in affect following an affect-induction (N = 262). The current findings support some theoretical understandings of broad personality traits and their relationships to general affect, and also suggests some refinements.
