Jin, Z., Shiomura, K.（潮村公弘）, & Jiang, L. (2015). Assessing implicit mate preferences among Chinese and Japanese women by providing love, sex, or money cues. 女性の潜在的な配偶者選好の日中比較 Psychological Reports, 116(1), 195-206. doi: 10.2466/21.PR0.116k11w6
Love, sex, and money are the most direct cues involved in the fundamental forms of mate preferences. These fundamental forms are not mutually exclusive but are interrelated. As a result, humans base their mate choices on multiple cues. In this study, 62 undergraduate women (M age = 20.4 yr., SD = 1.4) from China and Japan served as the participants. They performed a variation of the semantic priming task, in which they were instructed to decide by means of a key-press whether the target was human or non-human. The primes were images that portrayed potent evolutionary factors for mate preference (i.e., love, sex, and money), and the manipulation was based on whether the prime and target matched regarding gender, independent of the target decision task (human vs non-human). Participants gave faster responses to male targets than to female targets under priming. The results generally supported the evolutionary premises that assume mate preference is determined by fundamental forms of providing emotional (love), material (money), and fertility support (sex). The money priming effect was stronger in the Chinese women than in the Japanese women, suggesting that social context may influence mate preferences.

Tabuchi, M.（田渕恵）, & Miura, A.（三浦麻子） (2015). Young people’s reactions change elderly people’s generativity and narratives: The effect of intergenerational interaction on the elderly. 若者の反応が高齢者の世代性と語りを変える：世代間相互作用の効果 Journal of Intergenerational Relationships, 13(2), 118-133. doi: 10.1080/15350770.2015.1026298
The aim of this study was to investigate the effect of the young listener’s reaction on the development of generativity and narratives of elderly people. Thirty-four males between the ages of 60 and 82 participated in this experiment in which the listener generations (young/elderly) and listener reactions (empathic/neutral) were controlled. The participants shared and taught their wisdom gained from their past experiences through narratives. Results showed that many elderly people spoke about “lessons from experiences of failure” when there was an empathic reaction from young people, and such narratives were promoted by an increase of generativity. These results suggested the impact of the younger people’s reaction on the elderly people’s psychological development and behavior.

Yoshimura, A., Lebowitz, A., Bun, S., Aiba, M.(相羽美幸), Ikejima, C., & Asada, T. (2015). A comparative analysis of dementia inpatient characteristics: Results from a nationwide survey of different care facilities in Japan. 介護施設による認知症患者の特徴の比較：全国の介護施設を対象とした調査から Psychogeriatrics. doi: 10.1111/psyg.12117
Background
In Japan, the number of dementia patients admitted to hospitals and other care facilities has been increasing and their hospital stays prolonged. Until now, there has been no study examining the differences between patients in psychiatric hospitals and other care facilities. Here we attempt a comparative analysis of characteristics of dementia patients in psychiatric hospitals and other types of facilities based on a nationwide survey.
Method
A nationwide, cross-sectional survey was conducted in 2009–2011. Questionnaires were sent to randomly selected facilities and asked about each facility’s status as of September 2009 and about individuals with dementia residing in each facility during the 2008 fiscal year. The portion about individuals consisted of items to assess eligibility for the Long-Term Care Insurance programme. Based on data from 6121 patients residing in seven different types of facilities, features of dementia patients in psychiatric hospitals and differences among facilities were analyzed.
Results
There was a significant difference in average age, activities of daily living level, and dementia severity level among the seven types of facilities. The average age in all types of facilities, except for psychiatric hospitals, was higher than the national average life expectancy of 82.59 years. The results of the study revealed that in psychiatric hospitals the proportion of men, those aged <75 years, demented patients with severe behavioural and psychological symptoms of dementia, and those with frontotemporal dementia was significantly greater than in other types of facilities. In other Long-Term Care Insurance care facilities, dementia patients >80 years and women accounted for 80% of all patients.
Conclusion
Result showed that dementia patients in psychiatric hospitals had a higher proportion of men, younger age groups, and severe dementia than other types of facilities. These features contrast markedly with status of dementia patients in other Long-Term Care Insurance care facilities. In order to facilitate dementia patients’ early discharge from psychiatric hospitals to other care facilities or to home, further fulfilment care services corresponding to severe dementia and early-onset dementia may be needed.

Muto, M. (武藤麻美), Kugihara, N. (釘原直樹), & Kohara, Y. (2015). Psychological distance and likeability of in- or out-group targets who hold different opinions. 内・外集団における異なる価値観の保持者に対する心理的距離：戦争の是非をテーマとして Psychologia, 58, 36-48.
This study investigated whether the extension of psychological distance from in- or out-group targets that hold different opinions covaried with increased negative impressions about such targets. A between-participants 2 (matching opinion vs. non-matching opinion presentations) x 2 (Japanese in-group presenter vs. American out-group presenter) factorial design was used. The results indicated the following: (1) in the matching opinion condition, participants reduced the psychological distance from out-group targets and increased their likeability: whereas (2) in the non-matching opinion condition, participants maintained the psychological distance from in-group targets and disliked them. These results indicate that the difference between actual and expected opinions that people have about targets affected the increase, or decrease of psychological distance and the likability of targets.

Thomson, R., & Yuki, M.（結城雅樹） (2015). How to win (and lose) friendships across cultures: Why relational mobility matters. 文化を越えて友情を勝ち得るには：関係流動性の問題 In-Mind Magazine.In this article, we have reviewed research which suggests that to understand which relational strategies work in what social context, it is important to understand the characteristics of external social environments which surround individuals, in particular relational mobility. This is called the socio-ecological approach to cultural and regional differences in mind and behavior, an approach which complements previous cross-cultural research. North American societies, as well as urban areas, are high in relational mobility, which means there are an abundance of options for interpersonal relationships. In such a social ecology, people tend to be more confident in their abilities, trust strangers, and be more open about sensitive personal matters. Behaving this way helps them in their goals of acquiring and keeping beneficial friendships. The social environments in East Asia and rural areas, however, tend to be low in relational mobility. Interpersonal relationships are generally pre-determined, and there are fewer options to meet new people. In a social ecology like this, it appears wise to avoid offending others. Doing so will help to maintain harmony in those long-lasting, hard to replace relationships. To put it in a nutshell: Sure, friendships can be tough, but they’re easier to manage if you’re aware of the rules of the game. |

The purpose of this study was to examine the effect of peer monitoring on generosity in boys and girls aged 6 – 12 years. A total of 120 elementary school students played a one-shot dictator game (DG) with and without peer monitoring by classmates. Children decided how to divide 10 chocolates between themselves and a classmate either in a condition in which their allocations were visible to their peers, or in private. While the effect of peer monitoring on the allocation amount in the DG was clearly present in boys, it was not observed in girls. Furthermore, the effect of peer monitoring in boys appeared at the age of 9 years. These results suggest that the motivation to draw peers’ attention plays a stronger role for older boys than for girls or younger boys. The potential roles of higher-order theory of mind, social roles, and emergence of secondary sex characteristics on the influence of peer monitoring on generosity shown by boys are discussed.

Kobayashi, T.（小林哲郎）, & Ichifuji, Y. (2015). Tweets that matter: Evidence from a randomized field experiment in Japan. ツイッターを利用した選挙運動の効果：日本における現場実験 Political Communication. doi: 10.1080/10584609.2014.986696 Although election campaigns are increasingly utilizing social media, only a few studies have investigated their effects experimentally. To fill this gap in the literature, we conducted a field experiment to examine the effects of a campaign that used Twitter during the 2013 House of Councillors election in Japan. The treatment was exposure to tweets from Tōru Hashimoto, the mayor of Osaka and co-leader of the Japan Restoration Party, who has the largest number of Twitter followers among Japanese politicians. Participants assigned to the treatment group followed Hashimoto and the two placebos, whereas those assigned to the control condition followed only the two placebos. They followed the politicians continuously for approximately one month. Pre- and posttreatment measures were collected using online surveys, and treatment compliance was continuously checked via Twitter application programming interface (API). Following Hashimoto on Twitter during the election campaign had a positive impact on feelings toward Hashimoto. This effect was not mediated by issue knowledge or the evaluation of Hashimoto’s personal traits, and no effects were observed on voting. These findings suggest that repeated exposure to a politician’s messages on Twitter may only result in a mere exposure effect, which nevertheless generates favorable overall attitudes about the politician.

Boase, J., Kobayashi, T.（小林哲郎）, Schrock, A., Suzuki, T., & Suzuki, T.（鈴木貴久）(2015). Reconnecting here and there: The reactivation of dormant ties in the US and Japan. 休眠していた絆の再接続：日米比較研究 American Behavioral Scientist.
This article examines the reactivation of dormant ties in Japan and the United States. Using the institutional approach to culture developed by Yamagishi et al., it is hypothesized that respondents living in Japan will be less likely to reconnect with dormant ties when prompted than respondents living in the United States. It is further hypothesized that interaction with kin and work ties will help to explain lower levels of reconnection in Japan than in the United States. To examine these hypotheses, we developed a field experiment in which 95 adults living in Japan and 68 adults living in the United States were prompted by a smartphone application to reconnect with dormant ties. The results of this study show strong support for the hypothesis that respondents living in Japan are less likely to reconnect with dormant ties than respondents living in the United States when prompted. There is also mixed support for the hypothesis that interaction with kin and work ties helps to explain lower levels of reconnection in Japan than in the United States.

Insisting on Depression, but not Showing Symptoms: A Japanese Study of Excuse-Making. 症状を呈さない鬱病の主張 International Journal of Psychological Studies, 7, 146-154. doi: 10.5539/ijps.v7n2p146 Since the late 1990s, Japanese psychiatrists have reported the appearance of a Modern Type Depression (MTD), which has different features from melancholic depression. Using a case vignette method, we looked at one of the distinctive features of MTD; that is, “insisting on depression”. In particular, we examined whether the statement “I think I may have depressive disorder” can be accepted as an excuse for not fulfilling ones’ duty when one does not show any symptoms of depressive disorder. Participants comprised 344 Japanese undergraduates who were presented with a short scenario describing social predicaments and who subsequently assessed the excuse value in terms of impression and behavioral reaction on the transgressor. Results showed that even though the transgressor did not show any symptoms of depressive disorder, insisting that one may have depressive disorder seemed to be accepted. Additionally, consistent with Weiner’s cognitive (attribution)–emotion–action model, the more positive impressions observers have on the transgressor, the more they are motivated to react kindly to the transgressor. Some unexpected findings and limitations of the present study were discussed.
いわゆる「新型うつ」はその特徴の一つとして，自ら積極的に「うつ（病）である」と主張することが挙げられています。そしてこの特徴に対して，「うつ（病）である」ということを不都合に対する弁解にしている面があるのではないか，という指摘があります。本研究はこの点について，自己呈示理論（弁解研究）をベースとして検討しました。大学生を対象に，場面想定法を使った質問紙実験を実施した結果，たとえ事前にうつ病の症状を示していなくても，失敗した後に「自分はうつ病だと思う」と発言することは，印象の悪化，あるいは罰や叱責といった否定的な反応を抑える妥当な弁解として機能することが示唆されました。

Ito, K., Masuda, T.（増田貴彦）, Koyama, A.（小宮あすか）, & Hioki, K.（日置孝一）(2015). Seeking help from close, same-sex friends: Relational costs for Japanese and personal costs for European Canadians. 親密な同性友人に援助を求める際のコストの文化差 Journal of Social and Personal Relationships, 32(4), 529-554. doi: 10.1177/0265407514539780
Seeking help from close friends is beneficial for help seekers but also entails costs. Past research on social support suggested that East Asians were more likely than their North American counterparts to perceive relational costs (e.g., causing trouble for close friends), whereas North Americans tended to selectively perceive personal costs (e.g., admitting incompetence). We first collected European Canadian and Japanese people’s everyday experiences of help-seeking behaviors. We then examined whether norms would mediate the relationship between perceptions of costs and expected closeness in friendship. For European Canadians, we found such meditating relationships only for personal costs; whereas for the Japanese, the relationships were observed for both personal and relational costs. Implications for social cognitive research and clinical research are discussed.
