  • My research theme is how human cognition is adaptive in a culture and I focuses on the distinction between rule-based inference of Westerners and dialectic inference of Easterners. Currently, I am also interested in moral reasoning from the view that humans have two kinds of cognitive system: Evolutionarily recent system and old system.

    © 2016 by IGI Global. All rights reserved. Some may still have a stereotypical image that Japanese employees work like a robot, and achieved the industrial development even though they are not logical thinkers. This chapter is against this based on the latest cross-cultural studies. The conclusions are as follows. (1) Even if Japanese appears to be illogical in the sense that they are less likely to do rule-based thinking, this does not means that they are less intelligent. (2) Easterners are more likely to do dialectical thinking. (3) Easterners' naïve dialecticism is strongly associated with cultural tradition, and it is plausible that it has been developed in a highcontext culture. (4) Japanese people may have a collectivist culture, and it is not an undeveloped culture comparing with an individualist culture as shown in the case of 'nemawashi'. Finally, it is proposed that the distinction between Westerners' low-context culture and Easterners' high-context culture provide important implications for globalizing business and that the notions of global mindset and 'glocal' are important for international business.


  • Two methods to measure the level of trust of Americans and Japanese: A cross-cultural study

     View Summary

    © The Author(s) 2014. Interpersonal trust of Japanese and Americans was investigated using two methods: a General Trust Questionnaire and a scenario judgments task, in which participants were asked to rate how strongly they trust a target person in a series of vignettes. Participants were grouped into two conditions, with the target person being either an in-group member or an outgroup member. The purposes of this study were to investigate whether Americans have a higher level of trust than Japanese do, to test the in-group hypothesis which predicts that the difference in trust between the two conditions is greater for Japanese than for Americans and the dialectical thought hypothesis which predicts that the correlation between the General Trust Questionnaire score and the scenario judgments task score would only occur in the Americans’ data. The study, which was conducted with American (n = 105) and Japanese (n = 102) participants, found no differences in the trust level between Americans and Japanese in both methods. The results did not support the in-group hypothesis, but did support the dialectical thought hypothesis, indicating that Japanese are more dialectical in judging how they trust others.
