Great ape origins of personality maturation and sex differences: a study of orangutans and chimpanzees.

Human personality development evinces increased emotional stability, prosocial tendencies, and responsibility. One hypothesis offered to explain this pattern is Social-Investment Theory, which posits that culturally defined social roles, including marriage and employment, are responsible for the increased maturity. Alternatively, Five-Factor Theory emphasizes the role of biological factors, such as those governing physical development, which may predate the emergence of humans. Five-Factor Theory, unlike Social-Investment Theory, predicts that all or some of the human personality developmental trends should be present in great apes, our closest evolutionary relatives. To test this prediction and to better understand the evolutionary origins of sex differences, we examined age and sex differences in the chimpanzee and orangutan personality domains Extraversion, Dominance, Neuroticism, and Agreeableness. We also examined the Activity and Gregariousness facets of Extraversion and the orangutan Intellect domain. Extraversion and Neuroticism declined across age groups in both species, in common with humans. A significant interaction indicated that Agreeableness declined in orangutans but increased in chimpanzees, as it does in humans, though this may reflect differences in how Agreeableness was defined in each species. Significant interactions indicated that male chimpanzees, unlike male orangutans, displayed higher Neuroticism scores than females and maintained higher levels of Activity and Dominance into old age than female chimpanzees, male orangutans, and female orangutans. Personality-age correlations were comparable across orangutans and chimpanzees and were similar to those reported in human studies. Sex differences were stronger in chimpanzees than in humans or orangutans. These findings support Five-Factor Theory, suggest the role of gene-culture coevolution in shaping personality development, and suggest that sex differences evolved independently in different species.

Neuroticism developmental courses--implications for depression, anxiety and everyday emotional experience; a prospective study from adolescence to young adulthood.

BackgroundNeuroticism is frequently discussed as a risk factor for psychopathology. According to the maturity principle, neuroticism decreases over the course of life, but not uniformly across individuals. However, the implications of differences in personality maturation on mental health have not been well studied so far. Hence, we hypothesized that different forms of neuroticism development from adolescence to young adulthood are associated with differences in depression, anxiety and everyday emotional experience at the age of 25.MethodsA sample of 266 adolescents from the general population was examined three times over ten years (age at T0: 15, T1: 20 and T2: 25) using questionnaires, interviews and ecological momentary assessment (EMA). At all measurement points, neuroticism was assessed with the NEO inventory. At T2, diagnoses of major depression and anxiety disorders were captured with a structured clinical interview (M-CIDI). Phone-based EMA was used to assess emotional experience and affective instability over a two-week period at T2.ResultsThe best fitting model was a latent class growth analysis with two groups of neuroticism development. Most individuals (n = 205) showed moderate values whereas 61 participants were clustered into a group with elevated neuroticism levels. In both groups neuroticism significantly changed during the ten year period with a peak at the age of 20. Individuals with a higher absolute level were at 14-fold increased risk for depression and 7-fold risk for anxiety disorders at the age of 25. In EMA, increased negative affect and arousal as well as decreased positive emotions were found in this high group.ConclusionsOther than expected, personality did not mature in our sample. However, there was a significant change of neuroticism values from adolescence to young adulthood. Further, over 20% of our participants showed a neuroticism development which was associated with adverse outcomes such as negatively toned emotional experience and a heightened risk to suffer from depressive and anxiety disorders in young adulthood. These high-risk persons need to be identified early to provide interventions supporting continuous personality maturation.Electronic supplementary materialThe online version of this article (doi:10.1186/s12888-014-0210-2) contains supplementary material, which is available to authorized users.

Treating personality-relationship transactions with respect: narrow facets, advanced models, and extended time frames.

Contrary to premises of dynamic transactionism, most studies investigating personality-relationship transaction only found personality effects on relationships but failed to find effects of relationship experiences on personality development. The current study reconsiders this issue in 3 ways. First, alongside the broad Big Five characteristics (Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness), specific personality facets were considered to make comparisons with relationships more symmetric. Second, a recent extension of latent change modeling was applied allowing for a theoretically more appropriate model that compensates for the shortcomings of traditionally used cross-lagged panel or growth curve models. Third, personality-relationship transaction was studied from young adulthood to midlife using a 15-year longitudinal study with 654 German adults. Results showed patterns of personality-relationship transaction with the romantic partner, friends, kin, and other interaction partners. Specifically, the development of Neuroticism, Agreeableness, and Conscientiousness and their facets was closely interacting with partner and friend relationships, underlining the importance of these relationships for personality maturation during the adult years. We conclude that relationship effects have often been underestimated in previous studies. They are not bound to specific developmental periods, such as emerging adulthood, but their detection depends on the modeling approach and the analysis level (broad dimensions vs. facets). Relationship effects are most likely to occur in relationships that reflect self-selected life styles and circumstances.

Personality development in romantic relationships

Romantic relationships are associated with personality maturation, particularly with a decrease of neuroticism. As the mechanisms underlying this development are not well understood, I assume that changes in specific personality-congruent information processing play a major role for maturation within this context. Specifically, the relationship-specific interpretation bias (RIB; Finn, Mitte, & Neyer, 2013) which is described as the tendency to interpret ambiguous partner and relationship scenarios in a rather negative way should decrease in emerging relationships. I propose that particularly recent decreases in the RIB may explain romantic partner’s maturation to more emotionally stable individuals. Data from a four-wave longitudinal study over nine months (N = 287 couples) that were analyzed in a so-called latent dyadic change-change model will be presented. Results indicate intra- and interpersonal maturation effects within this sample of newly enamored couples and point to the usefulness of detailed change analyses to uncover potential mechanisms of development.

Personality Maturation Around the World

During early adulthood, individuals from different cultures across the world tend to become more agreeable, more conscientious, and less neurotic. Two leading theories offer different explanations for these pervasive age trends: Five-factor theory proposes that personality maturation is largely determined by genetic factors, whereas social-investment theory proposes that personality maturation in early adulthood is largely the result of normative life transitions to adult roles. In the research reported here, we conducted the first systematic cross-cultural test of these theories using data from a large Internet-based sample of young adults from 62 nations (N = 884,328). We found strong evidence for universal personality maturation from early to middle adulthood, yet there were significant cultural differences in age effects on personality traits. Consistent with social-investment theory, results showed that cultures with an earlier onset of adult-role responsibilities were marked by earlier personality maturation.

707 – Spirituality and its relationship with personality and suicidality in depressed people - cross sectional study

The relationship between spirituality and personality is complex in the patients with depression. Some considerations precede that concept of spirituality is based in personality and mediate some of the effects of personality on mental health (e.g. suicidal risk). Here we examined the associations between spirituality (measured by WHO-SRPB), depression (measured by Beck Depression Inventory), suicidal risk (measured by Beck Hopelessnes Scale), and temperament and character dimensions (measured by Temperament and Character Inventory) in 74 patients with depressive disorder. Our data indicate that spirituality had a positive association with depression and suicidal risk, and presented as predictor of lower depressive symptoms and suicidality. Further, the dimension Self- directedness is associated with patients spiritual resources. As it emphasises patient' level of personality maturation, including of spiritual issues in therapeutic process with patients should be further explored.

Examining Mechanisms of Personality Maturation: The Impact of Life Satisfaction on the Development of the Big Five Personality Traits

Individuals are expected to mature with increasing age, but it is not yet fully understood which factors contribute to this maturation process. Using data of a representative sample of Germans (N = 14,718) who gave information about their Big Five personality traits twice over a period of 4 years, we identified satisfaction with life, which was reported yearly, as an important variable for explaining mechanisms and interindividual differences in personality maturation. Dual latent change models suggest that more satisfied (compared to less satisfied) individuals experience more positive changes in Emotional Stability, Agreeableness, and Conscientiousness and that positive changes in life satisfaction are associated with positive changes in personality. Furthermore, maturation processes were examined for individuals who faced a social role transition, namely, marriage, birth of a child, or entering the job market. Again, differential effects highlight the importance of life satisfaction for personality maturation.

Hitting the Road to Adulthood

Previous research suggests that normative life transitions have the potential to trigger personality maturation. But what exactly happens during such a transitional stage? The present study examined personality trait changes in a sample of 910 German high school students during their transition from school to adult life. Despite the short observation period of three semiannual measurements, growth curve analyses revealed significant mean-level changes in personality traits. These changes occurred primarily in a positive direction, were strongest for the trait of conscientiousness, and most pronounced in those students who were directly confronted with this transitional experience. Bivariate growth curve models indicated that individual differences in personality change were substantially associated with changes in students' investments into achievement behavior. Supporting socioanalytic perspectives on personality development, these findings can be discussed with respect to process approaches to personality change assuming that consistent behavioral changes might lead to personality change in a bottom-up fashion.

Neural Network Development in Late Adolescents during Observation of Risk-Taking Action

Emotional maturity and social awareness are important for adolescents, particularly college students beginning to face the challenges and risks of the adult world. However, there has been relatively little research into personality maturation and psychological development during late adolescence and the neural changes underlying this development. We investigated the correlation between psychological properties (neuroticism, extraversion, anxiety, and depression) and age among late adolescents (n = 25, from 18 years and 1 month to 22 years and 8 months). The results revealed that late adolescents became less neurotic, less anxious, less depressive and more extraverted as they aged. Participants then observed video clips depicting hand movements with and without a risk of harm (risk-taking or safe actions) during functional magnetic resonance imaging (fMRI). The results revealed that risk-taking actions elicited significantly stronger activation in the bilateral inferior parietal lobule, temporal visual regions (superior/middle temporal areas), and parieto-occipital visual areas (cuneus, middle occipital gyri, precuneus). We found positive correlations of age and extraversion with neural activation in the insula, middle temporal gyrus, lingual gyrus, and precuneus. We also found a negative correlation of age and anxiety with activation in the angular gyrus, precentral gyrus, and red nucleus/substantia nigra. Moreover, we found that insula activation mediated the relationship between age and extraversion. Overall, our results indicate that late adolescents become less anxious and more extraverted with age, a process involving functional neural changes in brain networks related to social cognition and emotional processing. The possible neural mechanisms of psychological and social maturation during late adolescence are discussed.

Promotion of Well-Being in Person-Centered Mental Health Care.

An understanding of the mechanisms of personality development provides a systematic way to promote health as an integrated state of physical, mental, social, and spiritual well-being. Individual differences in personality are causal antecedents of the full range of psychopathology. The maturation with integration of personality appears to be an important mechanism by which diverse modalities of treatment promote wellness and reduce illness. First, the authors review the relationship between personality and a wide range of psychiatric disorders. Second, the authors evaluate the impact of character structure on a wide range of measures of well-being, including positive emotions, negative emotions, life satisfaction, perceived social support, and perceived health. Third, the authors describe a practical and inexpensive clinical method for facilitating the maturation and integration of personality based on an understanding of the processes of human thought, which underlie changes in personality and well-being.

Maturation of personality in adolescence.

The present research assesses adolescent personality maturation by examining 3 measures of change and stability (i.e., mean-level change, rank-order stability, and profile similarity) of Big Five personality traits, employing data from a 5-annual-wave study with overlapping early to middle (n = 923) and middle to late (n = 390) adolescent cohorts. Results indicated that mean levels of Agreeableness and Emotional Stability increased during adolescence. There was mixed evidence for increases in Extraversion and Openness. Additionally, rank-order stability and profile similarity of adolescent personality traits clearly increased from early to late adolescence. For all change facets, the authors found evidence for gender differences in the timing of adolescent personality maturation, as girls were found to mature earlier than boys.

Patterns and sources of adult personality development: Growth curve analyses of the NEO PI-R scales in a longitudinal twin study.

The present study examined the patterns and sources of 10-year stability and change of adult personality assessed by the 5 domains and 30 facets of the Revised NEO Personality Inventory. Phenotypic and biometric analyses were performed on data from 126 identical and 61 fraternal twins from the Bielefeld Longitudinal Study of Adult Twins (BiLSAT). Consistent with previous research, LGM analyses revealed significant mean-level changes in domains and facets suggesting maturation of personality. There were also substantial individual differences in the change trajectories of both domain and facet scales. Correlations between age and trait changes were modest and there were no significant associations between change and gender. Biometric extensions of growth curve models showed that 10-year stability and change of personality were influenced by both genetic as well as environmental factors. Regarding the etiology of change, the analyses uncovered a more complex picture than originally stated, as findings suggest noticeable differences between traits with respect to the magnitude of genetic and environmental effects.

Illness and personality maturation: The search for meaning in severe illness

Background In scientific literature, when the consequences of illness are discussed, one finds that the deficit perspective is prevailing: Illness as the cause for loss of abilities and a loss of contentment. On the other hand, particularly with creative people, an increase of creativity can be observed, following a confrontation with and having endured a period of illness. When one considers the occurrence of illness retrospectively in a biographical context, one may find often a biographical standstill. Although illness and disease are considered as a collapse, one may observe also psycho-spiritual maturation processes during the confrontation with illness. In several cases illness can thus result in personality maturation and a higher level of psychological health. Aims Despite of the fact that this phenomenon is known and communicated, little attention is paid to this aspect within the professional health care system. Thus we interviewed patients with respect to their opinion on the meaning of serious illnesses (narrative interviews; content analysis/structural hermeneutics), and run empirical investigations using the BioBeKe and AKU questionnaire. Methods The BioBeKe was developed to address the biographical consequences of chronic disease and consists of 2 item pools: The negative impact of disease is described by 2 factors (19 items, Cronbach′s alpha=0.96): Constraints of Life and Development; Resignation. The positive impact is described by 3 factors (20 items, Cronbach′s alpha=0.94): Life Reflection; Appraisal of Life; Social Contacts. Results Among the 96 individuals investigated so far, the positive factors were ranked higher than the negative factors. Univariate variance analyses revealed that age had a significant influence on Constraints (F=3.4), the educational level on Resignation ( F =4.8), the educational level and disease on Appraisal ( F =2.5), and age and education on Social Contacts, while none of these variables had a significant impact on Life Reflection. The negative factors correlated strongly with Escape from illness ( r >0.6), and negatively with life satisfaction ( r >−0.5), while the positive factors correlated with Reappraisal: Illness as Chance ( r >0.6). Particularly, Reflection and Appraisal correlated with intrinsic religiosity ( r =0.4). Preliminary results from 8 narrative interviews indicated that several patients believe that their illness experience triggered a ‘learning process’, resulting in a reconsideration of their lives and ascribed values to it. The process entailed also an opening towards transcendental/religious aspects, helping them to ‘make sense’ of their experience. Conclusions Although the study is still ongoing, the first results encourage to include biographical aspects into the doctor–patient discourse, and to learn how to address the topic of the search for meaning.

Relationships Matter in Personality Development: Evidence From an 8‐Year Longitudinal Study Across Young Adulthood

Personality-relationship transactions were investigated in a general population sample of young German adults with three assessments over 8 years. Four general findings were obtained. First, personality development was characterized by substantive individual differences in change. Second, bivariate latent growth models indicated that individual differences in personality change were substantially associated with change in peer and family relationships. Third, forming a partner relationship for the first time moderated the maturation of personality. This finding was replicated over two subsequent time intervals with independent subgroups. Fourth, higher neuroticism and higher sociability predicted which of the singles began a partner relationship during the next 8 years. The results confirm that individual differences in personality development predict and result from life transitions and relationship experiences.

Positive Adult Personality Development

Abstract. Does personality stay stable after young adulthood or is there continued change throughout middle and later adulthood? For decades, this question has caused heated debate. Over the last couple of years, a consensus has emerged based on recent cross-cultural as well as longitudinal evidence. This consensus confirms that indeed there is personality change in middle and later adulthood. Many authors have labeled this change personality maturation or growth. In somewhat simplified terms the observed pattern is as follows: neuroticism declines, conscientiousness and agreeableness increase. At the same time it has been argued that this pattern of personality change is the result of coping with the developmental tasks of adulthood and, thus, increased adjustment. We would like to examine this practice of equating developmental adjustment with growth and ask how to define personality growth. To answer this question, we consult theories of personality development as well as lifespan theory.

Repairing the bond in important relationships: a dynamic for personality maturation.

The author sought to establish a common set of interactional dynamics involved in growth-facilitating interpersonal relationships. Empirical studies of the three most common dyadic relationships associated with personality growth were reviewed: infant-mother attachment behaviors, the psychotherapeutic alliance, and the marital relationship. Empirical and clinical studies support the conclusion that growth is facilitated when a strong affective bond is established with an important other and the inevitable disruptions of this bond are repaired. Personality maturation across the lifespan has been attributed to the internalization of admirable qualities of important others. The data surveyed suggest that the interactional dynamics associated with internalization involve establishing a strong affective bond with an important other and repairing this bond's inevitable ruptures. It is both the rupture and the repair that are crucial.

Nature over nurture: Temperament, personality, and life span development.

Temperaments are often regarded as biologically based psychological tendencies with intrinsic paths of development. It is argued that this definition applies to the personality traits of the five-factor model. Evidence for the endogenous nature of traits is summarized from studies of behavior genetics, parent?child relations, personality structure, animal personality, and the longitudinal stability of individual differences. New evidence for intrinsic maturation is offered from analyses of NEO Five-Factor Inventory scores for men and women age 14 and over in German, British, Spanish, Czech, and Turkish samples (N = 5,085). These data support strong conceptual links to child temperament despite modest empirical associations. The intrinsic maturation of personality is complemented by the culturally conditioned development of characteristic adaptations that express personality; interventions in human development are best addressed to these.
