Individual Differences in Analytic Versus Holistic Thinking

The authors constructed the Analysis-Holism Scale (AHS) to measure analytic versus holistic thinking tendency. In Study 1, using exploratory and confirmatory factor analysis, a 24-item scale was developed. In Study 2, convergent and discriminant validities were tested. In Studies 3 and 4, the known-group difference validity was examined by comparing scores on the AHS of Americans and Koreans (Study 3) and of Korean students of Oriental medicine and Korean students of non-Oriental medicine majors (Study 4). Results of Studies 3 and 4 show that Koreans and Korean students of Oriental medicine scored higher on the AHS than did Americans and Korean students of non-Oriental medicine majors, respectively. Studies 5 and 6 tested predictive validity by examining associations of the AHS with performances on two cognitive tasks (categorization and causal reasoning). Data analysis shows that those with high scores on the AHS displayed the holistic pattern of performances on each task more than did those with low scores.

It’s a Wonderful Life: Mentally Subtracting Positive Events Improves People’s Affective States, Contrary to Their Affective Forecasts

The authors hypothesized that thinking about the absence of a positive event from ones life would improve affective states more than thinking about the presence of a positive event but that people would not predict this when making affective forecasts. In Studies 1 and 2, college students wrote about the ways in which a positive event might never have happened and was surprising or how it became part of their life and was unsurprising. As predicted, people in the former condition reported more positive affective states. In Study 3, college student forecasters failed to anticipate this effect. In Study 4, Internet respondents and university staff members who wrote about how they might never have met their romantic partner were more satisfied with their relationship than were those who wrote about how they did meet their partner. The authors discuss the implications of these findings for the literatures on gratitude induction and counterfactual reasoning.

Culture, Interpersonal Perceptions, and Happiness in Social Interactions

The authors examined cultural differences in interpersonal processes associated with happiness felt in social interactions. In a false feedback experiment (Study 1a), they found that European Americans felt happier when their interaction partner perceived their personal self accurately, whereas Asian Americans felt happier when their interaction partner perceived their collective self accurately. In Study 1b, the authors further demonstrated that the results from Study 1a were not because of cultural differences in desirability of the traits used in Study 1a. In Studies 2 and 3, they used a 2-week event sampling method and replicated Study 1. Unlike Asian Americans, African Americans were not significantly different from European Americans in the predictors of happiness in social interactions. Together, this research shows that interpersonal affirmation of important aspects of the self leads to happiness and that cultural differences are likely to emerge from the emphasis placed on different aspects of the self.

Residential mobility breeds familiarity-seeking.

Why are American landscapes (e.g., housing developments, shopping malls) so uniform, despite the well-known American penchant for independence and uniqueness? We propose that this paradox can be explained by American mobility: Residential mobility fosters familiarity-seeking and familiarity-liking, while allowing individuals to pursue their personal goals and desires. We reason that people are drawn to familiar objects (e.g., familiar, national chain stores) when they move. We conducted 5 studies to test this idea at the levels of society, individuals, and situations. We found that (a) national chain stores do better in residentially mobile places than in residentially stable places (controlling for other economic and demographic factors; Study 1); (b) individuals who have moved a lot prefer familiar, national chain stores to unfamiliar stores (Studies 2a and 2b); and (c) a residential mobility mindset enhances the mere exposure and familiarity-liking effect (Studies 4 and 5). In Study 5, we demonstrated that the link between mobility and familiarity-liking was mediated by anxiety evoked by mobility.

Becoming a Holistic Thinker: Training Effect of Oriental Medicine on Reasoning

The authors hypothesized that training in Oriental medicine would make students think in a more holistic way. Study 1 found that students of Oriental medicine exhibited a cyclic expectation of future change, a key characteristic of holistic thinking, more than did students in other majors, such that the former, not the latter, believed that if something was going up or going down, it would reverse its direction in the future. Study 2 found that students in Oriental medicine also possessed a more complex causal belief and hence considered a greater amount of information in causal attribution than did students in other majors. More important, such a complex causal belief increased with the length of training in Oriental medicine. Implications and future research are discussed.

Affective Facilitation and Inhibition of Cultural Influences on Reasoning

Research in South Korea and the United States examined how affective states facilitate or inhibit culturally dominant styles of reasoning. According to the affect-as-information hypothesis, affective cues of mood influence judgements by serving as embodied information about the value of accessible inclinations and cognitions. Extending this line of research to culture, we hypothesised that positive affect should promote (and negative affect should inhibit) culturally normative reasoning. The results of two studies of causal reasoning supported this hypothesis. Positive and negative affect functioned like “go” and “stop” signals, respectively, for culturally typical reasoning styles. Thus, in happy (compared to sad) moods, Koreans engaged in more holistic reasoning, whereas Americans engaged in more analytic reasoning.
