    The purpose of this study is to investigate how a microgravity environment affects spatial orientation, the cognitive system, and interpersonal relationships, hence changes in gravity reference frames. After leaving the terrestrial globe, astronauts experience drastic perceptual disturbances (temporary loss of the senses of spatial- and self-orientation). However, they gradually learn to adapt to the novel environment by developing new perceptual and behavioral skills. First, we examined video clips of an astronaut’s body movement inside the International Space Station (ISS) by using a motion video analysis technique. We discovered that a microgravity environment definitely affects spatial orientation. Second, we analyzed how social hierarchy organization, metaphorical expression, and psychological stabilization were affected by space adaptation.

    This study verified the influence of a punishment reference histogram on the sentences of lay judges. In Experiment 1, 80 undergraduates determined the prison terms of an offender in an audio trial. About half the students were shown a histogram with a peak of the punishment meted out in similar cases and the remainder a histogram without it. The peak was set as a relatively short prison term (5–10 yrs) considering the seriousness of the crime (murder). The result indicated that the peak-histogram group chose significantly shorter prison terms than did the non-peak-histogram group, suggesting that the peak influenced the former’s sentencing. Moreover, Experiment 2 showed that the peak of the histogram influenced participant sentencing more strongly than a table, although both held the same punishment data, and that the same shaped histogram of different data did not. From these results, we concluded that the anchoring effect of the histogram is most likely to be caused by the visual attractiveness of the peak.

    How do the news media stimulate political deliberation, political interest, and political knowledge? To compare the effects of online news with those of the traditional news media, we collected three types of data: a web-based survey, diary logs of mass media use, and access logs to news sites. The results showed that exposure to news media reinforced political interest and political deliberation. Online news use, however, facilitated only online deliberation, while exposure to TV and newspapers stimulated face-to-face conversation. In addition, online and TV news use had a direct effect on political knowledge. The results also showed that political conversation with the family had a direct effect on interest in politics and political knowledge, while political conversation with friends had a positive impact only on political interest. The implications of the findings were discussed in terms of how occasional political communication narrows the gap between the politically sophisticated and the less sophisticated.

    This study investigated why the restrained buying called reputational risk occurred after The Great East Japan Earthquake, focusing on the psychological factors influencing consumers. A preliminary investigation (N=112) identified affective (System 1) factors—“negative affect,” “association with Fukushima,” “support for quake-hit areas,” and “radiation anxieties”—and reason (System 2) factors—“knowledge-based judgment” and “rational decision”—based on the dual-process theory. Initially, the results of structural equation modeling (SEM) conducted on the main survey data (N=310) indicated the influence of multi-collinearity. Accordingly, the factors “negative affect,” “association with Fukushima,” and “radiation anxieties” were integrated as “anxiety over radiation and nuclear power.” The result of SEM on the refined model suggested this factor causes restrained buying while “support for quake-hit areas” is effective in its mitigation. Finally, future contingency plans to combat reputational risk were discussed based on the findings of this study.

    Body image disturbance and body image discrepancy considered as factors of body dissatisfaction and a drive for thinness were investigated. Participants were presented with new figural stimuli (contour drawings/silhouettes) ranging from thin to heavy developed based on real and objective data—human body size measurements and 3-D image data. Results indicated that female participants overestimated their body size, though the degree of overestimation is not particularly large. It is suggested that competition with members of the same sex generates body dissatisfaction and a drive for thinness. Furthermore, participants rated ideal body size thinner than their perceived body size. It was found that the differences between perceived body size and ideal body size relate to body dissatisfaction and a drive for thinness.
