Comparisons of Australians and Japanese on group-based cooperation

A cross-societal experiment with 49 Australian and 56 Japanese participants examined if the group heuristic account of ingroup-favoring behavior in a Prisoner's Dilemma game can be extended beyond the minimal group situation to a situation involving an enduring social category (i.e. participant's nationality). Participants played a Prisoner's Dilemma game five times, each time with a different partner. Two of the five partners were ingroup members, two were outgroup members, and the nationality of one partner was not known. Furthermore, one of the two ingroup (or outgroup) partners knew that the participant was a member of the same (or the other) nationality, and the other did not know it. The results indicated that the knowledge that the partner had about the nationality of the participant exerted an effect only when the partner was an ingroup member. No major difference was found between Australian and Japanese participants. An outgroup-favoring cooperation pattern was observed, but that pattern was shown to be a result of fairness concerns among Australian participants and of positive stereotypes of Australians among Japanese participants.     

Trust, Gullibility, and Social Intelligence

A series of experiments conducted in Japan by Yamagishi and his associates are presented, all consistently showing that high trusters (as measured with a general trust scale) are more sensitive than low trusters to information potentially revealing lack of trustworthiness in others and judge other people's choice in a one-shot prisoner's dilemma more accurately. Based on these findings, a new theoretical twist is introduced to the "emancipation theory of trust" originally proposed by Yamagishi & Yamagishi (1994), that emphasizes the relation-expansion role of trust in addition to the traditionally noticed relation-fortification role of trust. When opportunity cost for staying in a commitment relation is generally high, it is more advantageous not to stay in secure and stable commitment relations but to explore opportunities that lie outside, and yet such social exploration involves the risk of being exploited by untrustworthy people. It is thus a more gainful strategy to invest "cognitive resources" in the nurturing of "social intelligence" needed to detect signals of untrustworthiness. General trust may be conceived as a by-product of the development of such social intelligence. Those who have invested in the development of social intelligence can afford to maintain a high level of general trust, whereas those who have not are encouraged to assume that "everyone is a thief" and to refrain from pursuing potentially lucrative but risky outside opportunities.     

Postmodern consciousness in psychotherapy

Modern consciousness is a cultural and historical achievement in the West and a developmental task for each person now. Modern consciousness consists in the emancipation from the power of community, animistic nature and the unconscious. It is connected with neurosis and psychotherapy because it has to do with inner conflicts. But today there is an increasing number of cases which are characterized by dissociation and acting out, without the feeling of conflicts. Consciousness seems to be changing toward a new conception which might be called 'postmodern consciousness'. The essence of postmodern consciousness is shown by interpreting two dreams internally. The first dream from a case of depersonalization indicates that it is not necessary to be entangled with the object. There is a different kind of coniunctio in the mode of seeing. The second dream from a case of dissociative disorder shows a world which has neither traces of pre-modern cosmology-high and low, here and the beyond-nor modern interiority. There is only surface and self-reflection without content. The discussion of dreams suggests that postmodern consciousness is not to be understood as premature and pathological. It is therapeutically important to refine and deepen postmodern consciousness.     

Why do people reject unintended inequity? Responders' rejection in a truncated ultimatum game

Rejection of an inequitable and yet unintended outcome in a truncated ultimatum game was examined in an experiment with 46 undergraduate students (27 men and 19 women) from a large national university in Japan. In an ultimatum game, one of two players, the proposer, makes an offer to divide a fixed-sum of money. The other player, the responder, decides whether to accept or reject the offer. When the responder rejects the proposer's offer, neither of the two players receives a reward. Previous work examining the behavior of participants in the truncated ultimatum game employed strategy method in their experimental design. We examined whether these previous findings would be replicated in an experimental design that did not use the strategy method and instead used the standard one-shot game. Seven out of 46 responders given an inequitable offer rejected it, replicating prior results with the strategy method. We further found that subjects who rejected an offer that was involuntary and yet inequitable did not over-attribute intentions to the proposer's involuntary behavior more strongly than did acceptors. These findings strongly suggest that aversion to inequity is the explanation for the subjects' rejection of the inequitable offer.     

Group Dynamics in Japan

Studies in group dynamics in Japan, which started just after the Second World War, are reviewed. This review categorizes the studies into two classes: those conducted in the first generation (up to the 1970s) which still remain influential today, and those which represent the current major research trends in the area. The first generation is characterized by a strenuous catching up of studies conducted in the U.S. The second generation has been a theoretical and empirical expansion of the area, and has emphasized the bilateral, dynamic relations between the nature of human collectivities (including culture) and the individuals' psychological state. It has been increasingly recognized that what was regarded as an individual psychological phenomenon in the past should be re-examined from the viewpoint of group dynamics. This goes beyond the traditional definition of small groups research in the laboratory setting. Group dynamics is developing as a field of study in which any kind and size of human collectivity is investigated regarding its dynamic nature and functions that provide a life-world appearing in front of each individual in the collectivity.     

A formal system for classical particle mechanics,its model-theoretic applications and space-time structure

In the history of Newtonian Mechanics physicists and astronomers did not rely on so-called inertial frames, indeed they were not able to identify such frames. So the usual neo-Newtonian formalism of Newtonian Mechanics contains some superfluous components. In the present paper I will formulate a formal system for classical particle mechanics in Leibnizian space-time, where a relation, a counterpart of the second law of motion, between force on bodies and derivative of their momentum will be defined relative to every, inertial or not, reference frame. And I will present a view that in the research process under Newtonian mechanics the accumulation of those models of the relation that satisfied some realistic conditions determined an additional structure of non-rotating frames to Leibnizian space-time.     

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.     

Preemptive strike: An experimental study of fear-based aggression

The mere presence of a potential threat of attack was found to be sufficient to lead a significant proportion of participants to engage in preemptive attacks toward potential threats; this response occurred even without an incentive for either party to attack the other. We developed a new experimental game—the preemptive strike game (PSG)—to demonstrate this tendency for defensive aggression. We also found that the rate at which participants attacked an individual representing a potential threat was not influenced by their minimal group membership; participants were no less likely to preemptively attack a member of their own minimal group and no more likely to use aggression against members of another minimal group. These findings indicate a need to further examine the role that fear-based defensive aggression, rather than anger-based spiteful aggression, plays in inter-individual and inter-group conflict.
