Universal sex differences in the desire for sexual variety: tests from 52 nations, 6 continents,and 13 islands

Evolutionary psychologists have hypothesized that men and women possess both long-term and short-term mating strategies, with men's short-term strategy differentially rooted in the desire for sexual variety. In this article, findings from a cross-cultural survey of 16,288 people across 10 major world regions (including North America, South America, Western Europe, Eastern Europe, Southern Europe, Middle East, Africa, Oceania, South/Southeast Asia, and East Asia) demonstrate that sex differences in the desire for sexual variety are culturally universal throughout these world regions. Sex differences were evident regardless of whether mean, median, distributional, or categorical indexes of sexual differentiation were evaluated. Sex differences were evident regardless of the measures used to evaluate them. Among contemporary theories of human mating, pluralistic approaches that hypothesize sex differences in the evolved design of short-term mating provide the most compelling account of these robust empirical findings.     

Effects of Mentally Subtracting Positive Events on Affective Status in Japanese College Students

This study examined the effect on positive and negative emotions in Japanese college students of mentally subtracting grateful events. Participants (N = 62) were randomly assigned to one of the following three conditions: (a) writing with surprise the ways that a positive thing or event might never have happened or might never have been part of life (the mentally subtracting a present good [MS] group), (b) writing without surprise the ways in which a positive thing or event happened easily or was certain to become a part of life (the counting gratitude group), and (c) no writing control. The results of analysis of variance showed that the MS group experienced significantly increased positive emotion and decreased negative emotion between pre‐test and post‐test. Furthermore, the MS group showed significantly greater positive emotion than the control group at post‐test. Surprise mediated the effects of the MS group intervention on positive emotion but not on negative emotion. Issues related to gratitude induction and mediation of surprise are discussed.     

Gender differences in synchrony: Females in sync during unstructured dyadic conversation

Although previous studies have reported that individual prosocial traits generally enhance synchrony, gender as a social factor was not the subject of focus. The present study examined gender differences in synchrony by conducting three experiments on dyadic unstructured conversations with same-gender strangers. Synchrony was assessed by calculating the cross-wavelet coherence and determining the relative phase. As expected, through the three experiments, the female dyads showed a higher degree of synchrony, compared to the male dyads. Moreover, the conversation type (i.e., structured monologue vs. unstructured dialogue) did not moderate the gender effect (Experiment 2), while synchrony in the female dyads was influenced by the preceding conversation (Experiment 3). In contrast, through the three experiments, the role of the relative phase was unclear. The findings indicate that the social factor, gender, has an impact on synchrony, and that interpersonal sensitivity contributes to synchrony.     

Self‐criticism and self‐reassurance as mediators between mental health attitudes and symptoms: Attitudes toward mental health problems in Japanese workers

Japanese workers suffer high rates of mental health symptoms, recognised recently by the Japanese government, which has enacted workplace well‐being initiatives. One reason for poor mental health concerns negative attitudes about mental health problems such as shame, which may be mediated by self‐reassurance and self‐criticism. This study aimed to evaluate shame‐based attitudes toward mental health problems and explore the relationship between mental health attitudes, self‐criticism, self‐reassurance, and mental health symptoms. Japanese workers (n = 131) completed three measures: attitudes toward mental health problems, mental health symptoms, and self‐criticism/reassurance. A high proportion of workers reported negative attitudes about mental health problems. There were strong relationships between mental health attitudes, mental health symptoms, self‐criticism, and self‐reassurance. Path analyses revealed that the total and indirect effects (through self‐criticism and self‐reassurance) of mental health attitudes on mental health were larger than the direct effect alone. Hated‐self and family reflected shame were identified as predictors for mental health symptoms. The findings suggest the importance of self‐criticism and self‐reassurance in mental health and mental health attitudes. Implications for help‐seeking behaviours also are discussed. Interventions aimed at reducing self‐criticism and enhancing self‐reassurance are recommended to improve mental health attitudes and increase help‐seeking in Japanese workers.     

Casual Cynics or Disillusioned Democrats? Political Alienation in Japan

This paper examines the structure of political alienation among Japanese eligible voters, using data from the first, second, fifth, and sixth waves of the seven-wave Japanese Electoral Survey II (JES II). Political alienation can be expressed as comprising two dimensions, political trust and civic-mindedness. Males and people with more years of schooling are more allegiant in general; that is, they are both more trusting and more civic-minded. Evaluations of cabinet performance and support for democratic mechanisms are strongly related to political trust and civic-mindedness. Supporters of the Liberal Democratic Party (LDP) are no more civic-minded than average but are more trusting politically, whereas Japan Communist Party supporters are more civic-minded but a good deal less politically trusting than average. Independents are below the overall average on both the political trust and civic-mindedness dimensions. Even though party support is unstable, Japan's political system will not lose its stability as long as LDP supporters and independents constitute the majority of Japan's electorate. The advent of a new party capable of providing an alternative to the LDP is important to the future of Japanese democracy.     

Using the implicit association test across cultures: A case of implicit self-esteem in Japan and Canada

Previous research has suggested that implicit self-esteem might be universally positive. In the present study implicit self-esteem, as measured by the implicit association test (IAT), was found to be positive in both Japanese and Canadian participants. However, contrary to prior research, Japanese participants were found to have significantly lower implicit self-esteem than Canadians. Japanese participants also had lower scores on an exploratory measure of collective implicit self-esteem. In general, the results of the present study point to the complexities in the study of implicit self-esteem across cultures. Inconsistencies between the present and previous research might reflect divergent methodologies used in the IAT. The applicability of the IAT in a cross-cultural setting is discussed.
