    Personality maturation around the world:A cross-cultural examination of Social-Investment Theory

    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.

    The "Reading the Mind in the Eyes" Test (Eyes Test) is a widely used assessment of "theory of mind." The NIMH Research Domain Criteria recommends it as one of two tests for "understanding mental states." Previous studies have demonstrated an on-average female advantage on the Eyes Test. However, it is unknown whether this female advantage exists across the lifespan and across a large number of countries. Thus, we tested sex and age differences using the English version of the Eyes Test in adolescents and adults across 57 countries. We also tested for associations with sociodemographic and cognitive/personality factors. We leveraged one discovery dataset (N = 305,726) and three validation datasets (Ns = 642; 5,284; and 1,087). The results show that: i) there is a replicable on-average female advantage in performance on the Eyes Test; ii) performance increases through adolescence and shallowly declines across adulthood; iii) the on-average female advantage is evident across the lifespan; iv) there is a significant on-average female advantage in 36 out of 57 countries; v) there is a significant on-average female advantage on translated (non-English) versions of the Eyes Test in 12 out of 16 countries, as confirmed by a systematic review; vi) D-scores, or empathizing-systemizing, predict Eyes Test performance above and beyond sex differences; and vii) the female advantage is negatively linked to "prosperity" and "autonomy," and positively linked to "collectivism," as confirmed by exploratory country-level analyses. We conclude that the on-average female advantage on the Eyes Test is observed across ages and most countries

    Tune in to your emotions: a robust personalized affective music player

    The emotional power of music is exploited in a personalized affective music player (AMP) that selects music for mood enhancement. A biosignal approach is used to measure listeners’ personal emotional reactions to their own music as input for affective user models. Regression and kernel density estimation are applied to model the physiological changes the music elicits. Using these models, personalized music selections based on an affective goal state can be made. The AMP was validated in real-world trials over the course of several weeks. Results show that our models can cope with noisy situations and handle large inter-individual differences in the music domain. The AMP augments music listening where its techniques enable automated affect guidance. Our approach provides valuable insights for affective computing and user modeling, for which the AMP is a suitable carrier application

    Likeness and Dealbreakers: interpreting interpersonal compatibility from online music profiles

    Abstract. How much would a stranger know about you if they knew only the last song you listened to? Quite a bit, at least according to the stranger. Music taste often acts as proxy for our personalities, and we constantly perform this taste perception online. In our study, we find that good first impressions are common, bad first impressions are extreme, and that people pick up on many subtle cues about personality and whether they share common values based on data found in an online music profile. Similar motivations for listening to music and the perception of individuality are more highly valued than similar taste in genres or artists, suggesting that social media applications could benefit from incorporating these motivations in predicting compatibility between users

    Geographically varying associations between personality and life satisfaction in the London metropolitan area

    This is the accepted manuscript of the paper. The final version is available from PNAS at http://www.pnas.org/content/112/3/725.Residential location is thought to influence people?s wellbeing, but different individuals may value\ud the same residential areas differently. We examined how life satisfaction and personality traits are\ud geographically distributed within the U.K. London metropolitan area, and how the strength of\ud associations between personality traits and life satisfaction vary by residential location (i.e.,\ud personality?neighborhood interactions). Residential area was recorded at the level of postal districts\ud (216 districts, n=56,019 participants). The strength of associations between personality traits and life\ud satisfaction were dependent on neighborhood characteristics. Higher openness to experience was\ud more positively associated with life satisfaction in postal districts with higher average openness to\ud experience, population density and ethnic diversity. Higher agreeableness and conscientiousness\ud were more strongly associated with life satisfaction in postal districts with lower overall levels of life\ud satisfaction. The associations of extraversion and emotional stability were not modified by\ud neighborhood characteristics. These findings suggest that people?s life satisfaction depends, at least\ud in part, on the interaction between individual personality and particular features of the places they\ud live.This study was financially supported by Kone Foundation and the Academy of Finland (grant no.\ud 268388)

    Corruption revisited: the influence of national personality, culture, and wealth

    No full text
    Corruption is often seen as one of the root causes of pressing national and global challenges. The persisting stark national differences in corruption levels and their potential causes have thus attracted growing interest from international business scholars. The objective of this study was to re-examine key factors that predict levels of national corruption. Drawing on comprehensive personality data from over 5 million respondents across 87 nations, and numerous dimensions of national culture, the study examines the relative importance of national personality versus national culture and wealth as predictors of national corruption. Regression analysis found that collectivism (particularly societal practices pertaining to collectivism) and wealth were robust predictors of corruption. In contrast, there was no consistent support for the effects of the Big Five personality traits aggregated to the national level, above and beyond the effects of national culture and wealth. These findings highlight and specify the important role played by national culture, and call into question previous research on national personality and corruption. More broadly, our study further highlights the need to exert caution when examining the influence of national-level personality, and the need for cross-national personality researchers to improve the validity, interpretability, and replicability of their work
