東京電力福島第一原子力発電所の事故から5年以上たった今なお福島県の産物の風評被害は続いている。なぜ消費者は福島県の産物を危険視するのだろうか?2つの実験で行動免疫システムが活性化すると,汚染地域を過大に推定するかどうかを検討した。実験1では,プライミングの条件(病気の脅威条件vs.統制条件)に関係なく,慢性的に感染嫌悪傾向が高い人の方が低い人よりも,汚染地域を過大に推定していた。実験2では,感染嫌悪傾向が高い人では病気の脅威条件の方が統制条件よりも汚染地域を過大に推定していた。また感染嫌悪傾向が低い人では条件で差異はみられなかった。風評被害と行動免疫システムの関係について考察した。

The purpose of this study is to investigate consumer attitudes towards shopping in Japan. Factor analyses of data by 1,286 nonprobability online panels in a Web survey (in 2014) confirmed a hypothesized two-factor structure (the hedonic and utilitarian), but although the hedonic subscale had enough internal consistency, the utilitarian subscale had relatively low internal consistency. The correlations of the scores on consumer attitudes towards shopping with other measures, such as bargain orientation, impulsive buying tendency, and frugality, provided support for the criterion validity of each subscale. In many cases, these relationships were not affected by variables such as gender, life stage, and household income. Implications for the two-dimensional model of Japanese consumer attitudes towards shopping are discussed.

This study investigated the professional impact of “Japanese Journal of Psychology.” Thirty four psychological journals written in Japanese were selected to register articles in a new database. This database included approximately 23,900 articles published through 2010. Using citations extracted from the references and footnotes in these scholarly journals, the Psychology Citation Index for Japanese Papers was created. The citation impact factors in Japanese psychology was determined on the basis of the number of times a journal was cited, cumulative impact factors, and the cited half-life of the journal; five years was a valid period for impact factor of psychological journals in Japan. The changes in the 5-year impact factors of “Japanese Journal of Psychology” were reviewed by comparing it with other journals.

This study investigated whether affective reaction predicted by the extended self-evaluation maintenance (extended SEM) model (e.g., Beach & Tesser, 1995) would be applicable to close relationships with same-sex friends. Participants (N=232) recalled or imagined eight SEM situations (defined by crossing high and low self-relevance with high and low partner-relevance with whether self outperforms partner or partner outperforms self) with close friend (N=81), romantic partner (N=98), and acquaintance (N=53). They then reported affective reactions to these occasions. As a result, the pattern of sympathy reaction to the partner predicted by the extended SEM model in the high self-relevance domain was shown to close friend and romantic partner. For acquaintance, contrary to the prediction, the pattern of affective reactions predicted by the extended SEM model was shown, regardless of the self-relevance domain. These findings were discussed in terms of the basic assumption of the (original) SEM model and the tendency of Japanese students to think of a relationship even with an acquaintance as very important.

The Implicit Positive and Negative Affect Test (IPANAT) is an instrument for the indirect assessment of positive and negative affect. A Japanese version of the IPANAT was developed and its reliability and validity were examined. In Study 1, factor analysis identified two independent factors that could be interpreted as implicit positive and negative affect, which corresponded to the original version. The Japanese IPANAT also had sufficient internal consistency and acceptable test–retest reliability. In Study 2, we demonstrated that the Japanese IPANAT was associated with explicit state affect (e.g., PANAS), extraversion, and neuroticism, which indicated its adequate construct validity. In Study 3, we examined the extent to which the Japanese IPANAT was sensitive to changes in affect by assessing a set of IPANAT items after the presentation of positive, negative, or neutral photographs. The results indicated that the Japanese IPANAT was sufficiently sensitive to changes in affect resulting from affective stimuli. Taken together, these studies suggest that the Japanese version of the IPANAT is a useful instrument for the indirect assessment of positive and negative affect.

People with low self-esteem, when experiencing a threat to self-evaluation, reportedly tend to place higher value in a romantic partner as an indirect form of self-enhancement. This study examined whether such an indirect form of self-enhancement is also found when considering a close friend. Participants’ trait self-esteem was measured. Then, they participated in an experiment in which they experienced (or not) a threat to their self-evaluation. They were subsequently asked to evaluate their close friends and acquaintances using trait adjectives. The results showed that participants with low self-esteem valued their close friends and acquaintances highly when they experienced a threat, compared with those who did not experience one. Meanwhile, participants with high self-esteem devalued their close friends but not their acquaintances when they experienced a threat, compared with those who did not. These results suggest that people with high self-esteem devalue their close friends as an indirect form of self-enhancement. We discuss the need to examine the effects of the difference in relationship quality between a close friend and a romantic partner, as well as the cross-cultural differences in indirect forms of self-enhancement.
