Yamada, A. （山田歩）, & Kim, J-Y. (2016). Option-Splitting Effects in Poll Regarding Japan’s Right to Exercise Collective Self-Defense. 集団的自衛権行使をめぐる世論調査における選択肢分割の効果 Social Science Japan Journal. doi: 10.1093/ssjj/jyv034
Against the backdrop of heated debates within and outside Japan regarding Japan’s push for the right to exercise collective self-defense (CSD), the Japanese mass media have reported a series of polls on Japan’s exercise of its right to CSD, with significantly disparate results. In this article, we present one natural experiment and one controlled experiment that show that the disparate outcomes are due to the different ways the options are segmented. We conducted a comparative analysis of two questionnaires, one presenting two options of ‘approve’ and ‘disapprove’ and the other with three options, splitting the option of ‘approve’ into two answers presenting different means of approving the use of the right to CSD. As a result, more respondents chose ‘approve’ when the option was split into two. The result shows that option-splitting expands the respondents’ range of perception and psychological availability, which in turn raises the selection rate. This research implies that inducing the poll results through option-splitting is possible, which might eventually affect the policy-making process in democratic societies where public opinion polls affect policy.

Fermin, A. S. R., Sakagami, M., Kiyonari, T. （清成透子）, Li, Y.（李楊）, Matsumoto, Y. （松本良恵）, Yamagishi, T. （山岸俊男） (2016). Representation of economic preferences in the structure and function of the amygdala and prefrontal cortex. 扁桃体と前頭前野の構造と機能における経済的選好の表現 Scientific Reports, 6, 20982. doi: 10.1038/srep20982
Social value orientations (SVOs) are economic preferences for the distribution of resources – prosocial individuals are more cooperative and egalitarian than are proselfs. Despite the social and economic implications of SVOs, no systematic studies have examined their neural correlates. We investigated the amygdala and dorsolateral prefrontal cortex (DLPFC) structures and functions in prosocials and proselfs by functional magnetic resonance imaging and evaluated cooperative behavior in the Prisoner’s Dilemma game. We found for the first time that amygdala volume was larger in prosocials and positively correlated with cooperation, while DLPFC volume was larger in proselfs and negatively correlated with cooperation. Proselfs’ decisions were marked by strong DLPFC and weak amygdala activity, and prosocials’ decisions were marked by strong amygdala activity, with the DLPFC signal increasing only in defection. Our findings suggest that proselfs’ decisions are controlled by DLPFC-mediated deliberative processes, while prosocials’ decisions are initially guided by automatic amygdala processes.

We examined whether mastery goals promote greater score improvement on a cognitive test than performance goals and whether self-compassion and contingency of self-worth moderated the effect. Participants received either mastery or performance goals manipulation, failed on a difficult test, and took the test again after receiving the correct answers. Those with mastery goals showed a greater score improvement than those with performance goals, although post-failure state self-esteem did not differ between the two conditions. Moreover, the goals had a greater effect among (a) those with low rather than high self-compassion and (b) those with high rather than low competition contingency of self-worth. The findings suggest that by framing the task as a challenge rather than a threat, mastery goals encourage people to learn from failure more so than performance goals, especially when under high ego-threat.

The Internet, a global computer network enabling people to send and receive information anywhere in the world, also functions as a local medium of communication. This study focuses on the role of the Internet in transmitting local news and examines the effects of community population concentrations as socio-ecological environments on the use of local news media consumed online and offline. Data from 1367 respondents across 156 Japanese communities were used to analyze the relationships between type of community and type of news source. The findings suggest that people who live in highly populated communities tend more often to use the Internet to access local news, whereas those in less populated communities tend to use more traditional mass media. However, the results of this study did not show a relationship between population concentrations within communities and the acquisition of international news, nor did the social features of residents adequately explain the effects of population concentration on the acquisition of local news. These results are consistent with theoretical predictions based on network externalities, urbanism, and collective action. The findings indicate that local news consumption is embedded in local social contexts in a way that international news is not, reinforcing the importance of urbanism in the information age.

Humans often forward kindness received from others to strangers, a phenomenon called the upstream or pay-it-forward indirect reciprocity. Some field observations and laboratory experiments found evidence of pay-it-forward reciprocity in which chains of cooperative acts persist in social dilemma situations. Theoretically, however, cooperation based on pay-it-forward reciprocity is not sustainable. We carried out laboratory experiments of a pay-it-forward indirect reciprocity game (i.e., chained gift-giving game) on a large scale in terms of group size and time. We found that cooperation consistent with pay-it-forward reciprocity occurred only in a first few decisions per participant and that cooperation originated from inherent pro-sociality of individuals. In contrast, the same groups of participants showed persisting chains of cooperation in a different indirect reciprocity game in which participants earned reputation by cooperating. Our experimental results suggest that pay-it-forward reciprocity is transient and disappears when a person makes decisions repeatedly, whereas the reputation-based reciprocity is stable in the same situation.
Nozaki, & Koyasu (2016)
Nozaki, Y. （野崎優樹）, & Koyasu, M. (2016). Can we apply an emotional competence measure to an eastern population?: Psychometric properties of the Profile of Emotional Competence in a Japanese population. 情動コンピテンス尺度は東洋の人にも適用可能か？日本における情動コンピテンスプロフィールの心理測定学的特性の検証 Assessment, 23(1), 112-123. doi: 10.1177/1073191115571124
Researchers have repeatedly argued that it is important to determine whether the psychometric properties of an emotional competence measure hold in Eastern populations because there may be cultural variability in abilities linked with emotional competence. However, few studies have examined potential differences in an emotional competence measure in Eastern cultures. To fill this gap, we investigated the applicability of the Profile of Emotional Competence to a Japanese population. Results demonstrated measurement and structural invariance across our Japanese and the original Belgian data sets. As was found in the Belgian sample, this measure showed adequate convergent and criterion validity in the Japanese sample. Furthermore, the scores on this measure were stronger predictors of subjective health and happiness in the Japanese than Belgian population. This measure also showed incremental validity. Our results suggest that the Profile of Emotional Competence is applicable to the Japanese population, an Eastern society.

While some previous researchers have found that guilt encourages prosocial behaviour towards a victim at the expense of other people, others have found the opposite, that is, people allocate resources at the expense of themselves. The present research used a hypothetical scenario method to determine which of these patterns would be replicated in the collectivistic context of Japanese society. In addition, we separated the cause of feelings of guilt into having caused harm and being at fault, and examined in more detail the effect of guilt on prosocial behaviour. Our results show that, in line with the second set of previous researchers, participants who were induced to feel guilt for having caused harm were more likely to allocate their resources to their victim at the expense of themselves than were individuals in the no-harm condition. This suggests that differences in social context influence the effect of guilt on prosocial behaviour in different ways.

Old people have considerable experience and wisdom to share with young people; however, young people do not always listen to old people with gratitude. We conducted two studies to examine the effect of regulatory fit on young people’s gratitude toward old advisers. As predicted, young people felt more grateful to old advisers whose advice did not “fit” the advisees’ self-regulatory orientation, whereas young people felt more grateful to young advisers whose advice fit the advisees’ self-regulatory orientation (Web survey in Study 1, lab experiment in Study 2). Using these results, we propose an idea that may promote smoother intergenerational interaction in transmitting experience and wisdom from older to younger generations.
高齢者の経験や知恵を次世代に継承していくことは重要であるが，知恵の受け手である若者が常に送り手である高齢者に対して感謝できるわけではない。どのような高齢者の知恵に若者が感謝を抱くのかを明らかにすることを目指し，本研究では，送り手と受け手の制御焦点傾向が若者の感謝生起に影響するかを調べた。Study1(Web調査)およびStudy2(実験室実験)の結果，若者同士では制御焦点傾向が合致する方が相手に対して感謝を抱くのに対し，知恵の送り手が高齢者である場合は制御焦点傾向が合致しない方が相手に対して感謝を抱くことが明らかとなった。本研究の結果は，知恵の伝授という世代間コミュニケーションを円滑に行うためのヒントとなり得る。

Exploring the Role of Culture in Sexual Objectification: A Seven Nations Study. 性的客体化における文化の役割の探索的検討: 7カ国を比較して International Review of Social Psychology / Revue Internationale de Psychologie Sociale, 28(1), 125-152.
Sexual objectification – seeing or treating a person as a sexual object – has been the topic of considerable investigation. Building from a longstanding recognition of the potential importance of culture in sexual objectification, this paper focuses on the extent to which people in different parts of the world objectify themselves and others. We explored sexual objectification amongst 588 people in seven diverse nations (i.e., Australia, India, Italy, Japan, Pakistan, the UK, and the USA). Participants completed standard measures of self- and other-objectification. The results revealed that culture did affect self- and other-objectification, with objectification emerging more robustly in Australia, Italy, the UK, and the USA than it did in India, Japan, and Pakistan. These findings help support theoretical claims that culture matters for sexual objectification. Future research directions are discussed.

This book chapter shows a potential effect of the VAAs in Japan by asking the following research questions: To what degree do Japanese voters recognize parties’ policy positions correctly? Can Japanese voters identify and vote for the party closest to their policy preference? Whom should VAAs target? By analyzing the internet survey data of the 2010 House of Councillors election, we show that quite a few Japanese voters could not find or incorrectly identify a party close to their policy preference, and voters who have a small amount of correct information are more likely to vote incorrectly. We also found that VAAs is likely to be effective for young, female voters and those who are not usually exposed to political information and indifferent to politics.
