A different pattern was found for twin conflict: the more the twins differed in their temperament (specifically negative emotionality) with age, the more the conflict between them increased.

We used three large cross-sectional samples (Ns > 3000) covering 16–90 years of age with broad measures of the Big Five, Five-Factor, and HEXACO models. We examined age effects on the model parameters using local structural equation modeling. We found a high stability of the trait domain loadings, suggesting relatively stable trait domain compositions across age. Extraversion-Openness correlations increased across age for all three measures, whereas an increase in the Extraversion-Agreeableness and decrease in the absolute Neuroticism-Extraversion correlations only replicated across the five-dimensional models. Inter-individual differences in personality were similar across age in the trait domains and facets but differed substantially for item residuals. In summary, the structure and individual differences in broad personality traits is relatively stable across the adult lifespan, with most age-differences only affecting the item level.","PeriodicalId":51376,"journal":{"name":"European Journal of Personality","volume":" ","pages":""},"PeriodicalIF":5.9,"publicationDate":"2023-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45132096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Building upon Schwartz’s circumplex model, this study investigated stability and change of values during adolescence and their environmental precursors (i.e., parental rejection and community violence exposure). A sample of 773 Italian high school students (342 males; M age [Time 1] = 14.19, SD = 0.56) was assessed using self-report questionnaires across four waves. Rank-order stability coefficients were moderate for all values. Latent growth curve analyses revealed a significant linear increase in self-enhancement; all the other values displayed a quadratic shape in change over time, with a decline in the first part of the curve and a subsequent increase across time points. Overall, significant associations were found between environmental factors and the baseline levels of values. Value change over time was not significantly predicted by environmental factors except for openness to change, which was associated with paternal rejection. Specifically, high paternal rejection was linked with a faster decrease and a slower increase of openness to change over time. These findings highlight the importance of longitudinal studies when examining value change over time. Also, they suggest that environmental factors may play a significant role in shaping adolescent values.","PeriodicalId":51376,"journal":{"name":"European Journal of Personality","volume":" ","pages":""},"PeriodicalIF":5.9,"publicationDate":"2023-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45340704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Indicators capturing common and thus redundant variance are preferentially selected, whereas indicators capturing a large proportion of unique variance outside the broad trait domains are omitted from further research. Even recent research dealing with lower-level personality traits such as facets or nuances has invariably relied on inventories founded on this factor analytic approach. However, items can also be selected to ensure low instead of high communality amongst them. The expected predictive power of such item sets is higher compared to those compiled to capitalize on the indicators’ redundancy. To investigate this, we applied Ant Colony Optimization (ACO) to select personality-descriptive adjectives with minimal inter-item correlations. When used to predict the frequency of everyday life behaviors, this ‘crude-grit’ set outperformed a traditional big-five item set and sets of randomly selected adjectives. The size of the predictive advantage of the crude-grit set was generally higher for those behaviors that could also be predicted better by the big-five item set. This study provides a proof-of-concept for an alternative procedure for compiling personality scales, and serves as a starting point for future studies using broader item sets.","PeriodicalId":51376,"journal":{"name":"European Journal of Personality","volume":" ","pages":""},"PeriodicalIF":5.9,"publicationDate":"2023-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46560199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Overcoming some of these challenges, we examined shifts in the implicit cognitive structures in the Epic of Gilgamesh, which is one of the earliest surviving pieces of literature, circulating in various versions over a period of approx. 2000 years in ancient Mesopotamia. Using a canonical English translation, we applied natural language processing (NLP) and human coding to extract low-dimensional representations of the implicit personality structure in three different historical epochs. We found systematic shifts over time with increasing complexity and increasing resemblance of contemporary personality models in later periods. We discuss how lexical analyses of ancient texts using trait co-occurrence analyses can provide novel insights on the evolution of human behaviour of relevance for contemporary social and behavioural science and the study of ancient societies.","PeriodicalId":51376,"journal":{"name":"European Journal of Personality","volume":" ","pages":""},"PeriodicalIF":5.9,"publicationDate":"2023-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47320928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multiple theoretical approaches have proposed that such motive-specific positive affective contingencies (PACs) are central building blocks of motive dispositions and personality more broadly. In the current research, we put this claim to test and investigated individual differences with regard to motive-specific PACs in the affiliation and power domains. We measured PACs via spontaneous emotional reactions to motive-specific cues, as assessed by affect ratings and electromyographic (EMG) recordings of smile responses. Both of these PAC operationalizations were highly internally consistent and moderately to highly stable across time. Furthermore, motive-specific PACs were linked in a manner consistent with theory to measures of motive dispositions and to personality traits with motivational underpinnings (i.e., extraversion, agreeableness, and narcissism). Finally, in the affiliation domain, motive-specific PACs were linked to objectively assessed, key motivational outcomes (i.e., attentional orientation, behavior in daily life, and in the laboratory). Taken together, the findings underscore the relevance of affective contingencies for the understanding of personality and motivated behavior.","PeriodicalId":51376,"journal":{"name":"European Journal of Personality","volume":" ","pages":""},"PeriodicalIF":5.9,"publicationDate":"2023-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47381225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Self-determination theory (SDT) proposes that satisfying three basic psychological needs for autonomy, competence and relatedness (BNS) fosters optimal functioning, thriving, and positive affect. Meanwhile, broaden-and-build theory suggests that positive emotions predict future psychosocial resources such as need satisfaction. Previous research on the BNS–positive affect link has not sufficiently established to what extent changes in BNS precede changes in positive affect or vice versa. We tested this in two 3-wave longitudinal studies, conducted over 2 years in the UK (Study 1: N = 958) and over 2 months in Latin America (Study 2: N = 1200). Bivariate latent trait-state-occasion models revealed that within-person fluctuations in BNS significantly predicted subsequent fluctuations in positive affect in both studies, but fluctuations in positive affect predicted subsequent fluctuations in BNS only in Study 2. These findings consistently support SDT predictions, whereas they only partially support broaden-and-build theory predictions, helping to clarify the likely causal relations between BNS and positive affect.","PeriodicalId":51376,"journal":{"name":"European Journal of Personality","volume":" ","pages":""},"PeriodicalIF":5.9,"publicationDate":"2023-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43233936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Employing preregistered multilevel lasso estimation, we did not find any significant effects. While exploratory analyses generally confirmed this conclusion, they also identified some effects that might being worth to be considered in future research (e.g., perceived impact and perceived social status changes were associated with changes in agreeableness after experiencing a relationship breakup). In total, our moderators explained less than 2% of variance in personality traits. Nonetheless, our study has several important implications for future research on individual differences in personality change.
