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.     

When sex doesn’t sell to men: mortality salience,disgust and the appeal of products and advertisements featuring sexualized women

Although men typically hold favorable views of advertisements featuring female sexuality, from a Terror Management Theory perspective, this should be less the case when thoughts of human mortality are salient. Two experiments conducted in South Korea supported this hypothesis across a variety of products (e.g., perfume and vodka). Men became more negative towards advertisements featuring female sexuality, and had reduced purchase intentions for those products, after thinking about their own mortality. Study 2 found that these effects were mediated by heightened disgust. Mortality thoughts did not impact women in either study. These findings uniquely demonstrate that thoughts of death interact with female sex-appeal to influence men’s consumer choices, and that disgust mediates these processes. Implications for the role of emotion, and cultural differences, in terror management, for attitudes toward female sexuality, and for marketing strategies are discussed.     

Conserving Energy by Inducing People to Drive Less

We attempted to reduce college students' use of their cars with an online intervention. Every other day for 2 weeks, students reported the number of miles they had avoided driving. In a 2 × 2 design, participants received feedback about pollution avoided (e.g., CO₂ saved), financial feedback (e.g., gas money saved), or no feedback. A control group did not monitor their driving. Participants in all Web conditions reported driving less than the no‐Web control group. In addition, Web participants who received both kinds of feedback reported driving less than did those who received one kind or none. We discuss implications for research on energy conservation and offer an online feedback form to help readers reduce their own driving.     

Are positive emotions just as "positive" across cultures?

Whereas positive emotions and feeling unequivocally good may be at the heart of well-being among Westerners, positive emotions often carry negative associations within many Asian cultures. Based on a review of East-West cultural differences in dialectical emotions, or co-occurring positive and negative feelings, we predicted culture to influence the association between positive emotions and depression, but not the association between negative emotions and depression. As predicted, in a survey of over 600 European-, immigrant Asian-, and Asian American college students, positive emotions were associated with depression symptoms among European Americans and Asian Americans, but not immigrant Asians. Negative emotions were associated with depression symptoms among all three groups. We also found initial evidence that acculturation (i.e., nativity) may influence the role of positive emotions in depression: Asian Americans fell "in between" the two other groups. These findings suggest the importance of studying the role of culture in positive emotions and in positive psychology. The use of interventions based on promoting positive emotions in clinical psychology among Asian clients is briefly discussed.     

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.     

Pantomime and imitation of limb gestures in relation to the severity of Alzheimer's disease

The present study was designed to investigate the relationship between performance of limb gestures and the severity of Alzheimer's disease (A.D.). Apraxia tends to occur at later stages of A.D., and the severity of apraxia has been shown to vary with the severity of A.D. dementia. Participants were 19 mild (including 9 with no cognitive impairment and 10 with mild impairment) and 18 moderate A.D. patients as well as 25 controls and they were asked to pantomime (P) or imitate (both concurrent (CI) and delayed (DI)), eight transitive gestures to assess praxis performance. Results indicated that the moderate patients performed less accurately than mild and non-impaired patients, and that across all groups, the imitation conditions were performed less accurately than pantomime, relative to controls. Correlational analyses revealed that MMSE scores were correlated with all three performance conditions suggesting that impaired praxis performance may relate to more global impairment. Finally, a frequency analysis was conducted to examine whether A.D. patients showed patterns of apraxia as described in Roy's model (1996). Results indicated that A.D. patients showed greatest impairment on pattern 7 (deficits in P, DI, and CI), reflecting late-stage gesture production, with a greater frequency of moderate patients exhibiting each apraxic pattern.     

Bayesian Extended Redundancy Analysis: A Bayesian Approach to Component-based Regression with Dimension Reduction

Abstract

Extended redundancy analysis (ERA) combines linear regression with dimension reduction to explore the directional relationships between multiple sets of predictors and outcome variables in a parsimonious manner. It aims to extract a component from each set of predictors in such a way that it accounts for the maximum variance of outcome variables. In this article, we extend ERA into the Bayesian framework, called Bayesian ERA (BERA). The advantages of BERA are threefold. First, BERA enables to make statistical inferences based on samples drawn from the joint posterior distribution of parameters obtained from a Markov chain Monte Carlo algorithm. As such, it does not necessitate any resampling method, which is on the other hand required for (frequentist’s) ordinary ERA to test the statistical significance of parameter estimates. Second, it formally incorporates relevant information obtained from previous research into analyses by specifying informative power prior distributions. Third, BERA handles missing data by implementing multiple imputation using a Markov Chain Monte Carlo algorithm, avoiding the potential bias of parameter estimates due to missing data. We assess the performance of BERA through simulation studies and apply BERA to real data regarding academic achievement.     

Emotions and Creativity, East and West

This article is concerned with emotion, creativity, and the intersection of the two – creativity in the domain of emotion. We first present a framework for the analysis of emotion, a framework that recognizes the importance of biological influences but that also takes into account cultural and individual variations. We then describe the criteria – effectiveness, novelty, and authenticity – for judging a response as creative; the relative emphasis placed on these criteria, especially novelty and authenticity, helps account for East–West differences in aesthetic preferences (e.g., in the production and evaluation of works of art). Next, we explore the ability of individuals to be emotionally creative, that is, to acquire emotions that meet the criteria for creativity. Finally, we examine the "Four-Seven Debate," a classic in Korean Neo-Confucian thought, in light of our discussion of emotions and creativity.     

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.
