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.

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.

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.

The tele-cocooning hypothesis posits that mobile communication increases interaction with communication rich ties, while simultaneously weakening interaction with communication weak ties. In this study, we demonstrate how smartphones can be used to mitigate tele-cocooning behavior by stimulating interaction with communication weak ties. Using a smartphone application to collect non-identifying mobile communication log data, we conducted a field experiment with 193 Japanese participants. The treatment consisted of onscreen reminders designed to stimulate interaction with communication weak ties. The results indicate that the treatment promoted the activation of communication weak ties and the acquisition of information through those ties, suggesting that smartphones can be utilized to promote access to social capital.

Facebook’s global reach suggests good potential for recruiting research participants and collecting objective behavioral data for cross-cultural research. Previous literature suggests the usefulness of Facebook advertisements to recruit participants in single-country studies. However, Facebook advert use in multi-country studies has not yet been reported. Nor are there any reports about soliciting Facebook user data (via Facebook applications) using Facebook advertisements. This paper contributes to this gap in Internet research, reporting on the effectiveness of Facebook advertisements to recruit participants, and for soliciting anonymized Facebook user data, in a 20-country study about privacy concerns on Facebook. Over seven days, 399 Facebook users from 18 countries responded to country-targeted advertisements in 13 languages. Response rates (ratio of advert clicks to valid responses) per country varied from 0% up to 14%. Overall, two-thirds of the country response rates were below 5%, and many country samples were gender-biased due to confounding societal factors. We conclude that for multi-national studies, Facebook advertisements may have potential for simple participant recruitment for surveys, but has limitations for soliciting Facebook user data. For user data collection, methods such as Amazon Mechanical Turk and snowball sampling may be more effective, but can be limited in their international reach.

We predicted and supported the prediction that a ‘preference-expectation reversal’ would occur among Japanese but not among Americans. American and Japanese participants evaluated ideal-typical independent and interdependent persons on the negative–positive dimension, and estimated how others would evaluate these persons. They also indicated their preference for acting like each of the target persons; that is, which of the two target persons they would prefer to act like. Both the American and Japanese participants wanted to act like the typical independent person rather than the typical interdependent person. However, the Japanese participants expected that others would evaluate the interdependent person more positively than the independent person. This preference-expectation reversal was not observed among the American participants. Further analysis demonstrated that the American participants’ personal evaluations of the two targets were consistent with their preferences. The Japanese participants’ personal evaluation represented a compromise between their preferences and the expected responses of others. These results suggest that the culturally shared belief in Japan that interdependent persons would receive more positive evaluations than independent persons created an incentive for them to behave interdependently despite their preferences.

Recent experimental studies have accumulated evidence about self-punishment. In accordance with the evolutionary perspective that shame has a reputation-maintenance function, we speculated that shame would promote self-punishment. Accordingly, we tested whether proneness to shame would predict self-punishment. In the first phase of the experiment, 98 undergraduates completed the Test of Self-Conscious Affect (TOSCA), a standard measure of proneness to shame and guilt. About 2 months later, 50 of the original participants took part in a self-punishment experiment, in which they all unintentionally made an unfair resource allocation, and then had the opportunity to inflict self-punishment by abandoning some of the money they had allocated to themselves. The amount of money the participants relinquished was significantly correlated with their shame-proneness. The intensity of posttransgression shame mediated the effect of shame-proneness on self-punishment. These results provide support for the evolutionary theorization of shame as a reputation-maintenance emotion.

Reward and punishment is a classic theme in research on social dilemmas. More recently, it has received considerable attention from scientists working in various disciplines such as economics, neuroscience, and psychology. We know now that reward and punishment can promote cooperation in so-called public good dilemmas, where people need to decide how much from their personal resources to contribute to the public good. Clearly, enjoying the contributions of others while not contributing is tempting. Punishment (and reward) are effective in reducing free-riding. Yet the recent explosion of research has also triggered many questions. For example, who can reward and punish most effectively? Is punishment effective in any culture? What are the emotions that accompany reward and punishment? Even if reward and punishment are effective, are they also efficient — knowing that rewards and punishment are costly to administer? How can sanctioning systems best organized to be reduce free-riding? The chapters in this book, the first in a series on human cooperation, explore the workings of reward and punishment, how they should be organized, and their functions in society, thereby providing a synthesis of the psychology, economics, and neuroscience of human cooperation.

The valuable relationships hypothesis posits that people are inclined to reconcile with their valuable-relationship partners. Focusing on a particular type of credible conciliatory signal (i.e., costly apology), the present study tested this hypothesis from the perpetrator’s perspective. In Studies 1 and 2, after imagining that they had committed an interpersonal transgression against one of their real friends, participants (N = 529 and 311 in Studies 1 and 2, respectively) rated their willingness to incur a cost in order to apologize to the victim. Apology cost was operationalized as “canceling plans to make an apology as soon as possible” in Study 1, and as “offering compensation” in Study 2. The results showed that the instrumentality of the partner to achieving the participants’ goals would increase their willingness to make a costly apology, after controlling for the participants’ sex, version of the transgression scenario, closeness to the victim, and expected forgiveness of the victim. To ensure the external validity of this finding, Studies 3 and 4 asked participants to recall one of their interpersonal transgression experiences, and to report whether they had offered compensation for it (N = 190 and 224 in Studies 3 and 4, respectively). Study 3 confirmed the hypothesis, while Study 4 did not directly support it. However, Study 4 did show that participants were more willing to reconcile with their valuable partners. Taken together, these results indicate that the valuable relationships hypothesis applies not only to victims, but also their perpetrators as well.

We examine how the timing of trust violations affects cooperation and solidarity, including trust and relational cohesion. Past studies that used repeated Prisoner’s Dilemmas suggest that trust violations are more harmful when they occur in early rather than later interactions. We argue that this effect of early trust violations depends on cultural and individual differences in generalized trust. A laboratory study from high- and low-trust cultures (the United States vs. Japan) supported our claim. First, early trust violations were more harmful than late trust violations, but only for Americans; the pattern reversed for Japanese. Second, these patterns were mediated by individual differences in generalized trust. Finally, generalized trust also moderated the effect of trust violations in the United States but not Japan. By demonstrating that generalized trust is not only lower but also less important in low-trust cultures, our research advances our understanding of how culture affects the development of solidarity in exchange relations.

Previous studies demonstrated that fear of negative evaluation (FNE) moderates responses to exclusion in late-stage social outcomes (e.g., social judgements and behaviours). People with low levels of FNE show affiliative responses, feeling compelled to recover their sense of belonging, whereas people with high levels of FNE do not. This study examined whether FNE also moderates responses to exclusion in early-stage interpersonal perception, manifested in selective attention. The experiment using a dot-probe task revealed that exclusion led participants with low levels of FNE to increase attention to signs of social acceptance (i.e., smiling faces). It also revealed that exclusion led those with high levels of FNE to pay more attention to signs of social threat (i.e., angry faces) relative to those of social acceptance. Thus, exclusion makes the motivation to protect oneself from social threats dominant over the motivation to reestablish social bonds among those who fear negative evaluation.

The mirror system in the brain is considered to be a neural basis of sociality, but previous studies have been limited to primates. Here we report an experimental task to examine the mirror system in rats. We show that a rat could reach to a pellet and grasp and eat it in front of another rat that was observing the reaching, which indicates that the task will enable us to start exploring the rat mirror system.

We report findings from a chat log analysis of a support group in which two to five patients and one or two facilitators chatted in a virtual space; weekly sessions lasted 1.5 hrs. each, and we followed them over five years. In the virtual space, participants were represented by avatars with emotional expressions. Chat messages were analysed with a text-mining tool, exploring whether positive emotion words (e.g., ‘happy’), medicine-related words (e.g., ‘symptoms’), and informational/emotional-support messages (giving and receiving) would increase over time. We found that frequency of positive emotion words increased in Years 1-3 and remained constant thereafter; medical-related words did not increase until Year 5. Support messages increased from Years 1 to 3. Analysis of messages indicated that the patients’ and facilitators’ conversational roles changed as a sense of community emerged. The virtual support group appeared to promote positive emotions, trust among members, and mutual supportive relationships within the group.

Using the concepts of naive dialecticism (i.e. the tendency to tolerate contradiction) and psychological essentialism (i.e. the tendency to attribute a fixed essence to something) as different aspects of consistency perception, we examined patterns of perceived consistency of the self and national ingroup among Japanese and Australians. Compared to Australians, Japanese showed more naive dialecticism and less psychological essentialism for the self; however, this cultural difference was not found for their national ingroups. These findings suggest that lay theories are applied in a domain-specific manner, and the domains to which they are applied depend on culture.
