All individuals have multiple views of themselves. Whereas the consistency among the different aspects of identity is emphasized in Western cultures, the "multiple selves" are often viewed as coexisting realities in East Asian cultures. This research revisits the classic thesis in psychology that identity consistency is a prerequisite condition of(More)
The convergent and discriminant validities of well-being concepts were examined using multitrait-multimethod matrix analyses (D. T. Campbell & D. W. Fiske, 1959) on 3 sets of data. In Study 1, participants completed measures of life satisfaction, positive affect, negative affect, self-esteem, and optimism on 2 occasions 4 weeks apart and also obtained 3(More)
Research has demonstrated that certain genotypes are expressed in different forms, depending on input from the social environment. To examine sensitivity to cultural norms regarding emotional support seeking as a type of social environment, we explored the behavioral expression of oxytocin receptor polymorphism (OXTR) rs53576, a gene previously related to(More)
The relative importance of emotions versus normative beliefs for life satisfaction judgments was compared among individualist and collectivist nations in 2 large sets of international data (in total, 61 nations, N = 62,446). Among nations, emotions and life satisfaction correlated significantly more strongly in more individualistic nations (r = .52 in Study(More)
Psychologists have not determined the defining characteristics of extraversion. In four studies, the authors tested the hypothesis that extraversion facets are linked by reward sensitivity. According to this hypothesis, only facets that reflect reward sensitivity should load on a higher order extraversion factor. This model was tested against a model in(More)
Ecologies shape cultures; cultures influence the development of personalities. There are both universal and culture-specific aspects of variation in personality. Some culture-specific aspects correspond to cultural syndromes such as complexity, tightness, individualism, and collectivism. A large body of literature suggests that the Big Five personality(More)
Research has demonstrated that certain genotypes are expressed phenotypically in different forms depending on the social environment. To examine sensitivity to cultural norms regarding emotion regulation, we explored the expression of the oxytocin receptor polymorphism (OXTR) rs53576, a gene previously related to socio-emotional sensitivity, in conjunction(More)
The effect of life events on subjective well-being (SWB) was explored in a 2-year longitudinal study of 115 participants. It was found that only life events during the previous 3 months influenced life satisfaction and positive and negative affect. Although recent life events influenced SWB even when personality at Time 1 was controlled, distal life events(More)
The present research examined the interaction between genes and culture as potential determinants of individuals' locus of attention. As the serotonin (5-HT) system has been associated with attentional focus and the ability to adapt to changes in reinforcement, we examined the serotonin 1A receptor polymorphism (5-HTR1A). Koreans and European Americans were(More)
Evidence shows that people feel mild positive moods when no strong emotional events are occurring, a phenomenon known as positive mood offset. We offer an evolutionary explanation of this characteristic, showing that it improves fertility, fecundity, and health, and abets other characteristics that were critical to reproductive success. We review research(More)
