This study measured and analyzed the amount of saliva and the taste threshold in response to lighting conditions (illuminance and color temperature) in different ethnic groups. Ten Japanese and ten Chinese healthy non-smoking male college students participated in the study. According to the results of repeated-measure ANOVA, the effect of illumination on the amount of saliva was significant in the Japanese students, and the Chinese students showed same tendencies regarding their saliva response, but not significant. On the other hand, the effect of illuminance on the taste threshold was considered significant in both these groups. Regarding the effect of color temperature, this study found significant changes in taste threshold only for Chinese. It is interesting to note that significant differences in the taste threshold regarding a salty taste were seen between the subject groups. The results of the present study indicated that the lighting condition could be considered an important parameter of taste sensation.

To evaluate the influence on sleep by mobility and comfort on a mattress, we estimated subjective sleep feelings and measured sleep quality by polysomnography. Ten healthy subjects (4 males, 6 females), aged 62-67, were recorded, sleeping in a laboratory for two nights at a week interval under two crossover designed conditions (EMC: a mattress easy to move and comfortable by first impressions, DMU: a mattress difficult to move and uncomfortable by first impressions). The percentage of wakefulness in the first half of sleep time was significantly increased at DMU. Subjective sleep feelings were better at EMC and subjective evaluations at the time of arising showed EMC was easier to move and more comfortable. These results suggest that mobility and comfort on a mattress is important for better sleep.

In this study, neonates calming responses to three cases of noise, as well as 'no sound' case were assessed with behavioral indices. The three cases of noise are as follows; white noise, pink noise and brown noise. The subjects were 11 neonates (less than four days old). The subjects were exposed to each noise at 70 dB (A-weighted sound pressure level). It was clarified by experimental results that each noise calmed crying neonates down significantly in compare with the 'no sound' case. Particularly brown noise was most effective to calm down crying neonates, since there were marginally significant differences in coded behavioral score between brown noise and the other noises.

In this study, we investigated the effect of a serotonin transporter gene polymorphism (5-HTTLPR) on praise seeking need and rejection avoidance need in young Japanese males (n=111). The results showed that there was no difference in praise seeking need and rejection avoidance need between serotonin transporter gene polymorphism types; however, the correlation between praise seeking need and rejection avoidance need was different depending on the presence of particular serotonin transporter gene polymorphisms. We suggest that serotonin transporter gene polymorphisms should be regarded as one possible factor that affects the relationship between praise seeking need and rejection avoidance need.

This study examined the mental and physiological responses to degree of comfort in using sanitary napkins. During menstrual period two types of napkins (thin type, thick type) were used by 8 women each. The indexes were 5 point scale, heart rate (HR), ratio of low frequency and high frequency (LF/HF) of heart rate variability and salivary chromogranin A (CgA). The results of 5 point scale (subjective evaluation) showed the thin type napkins were more comfortable than the thick type napkins. The results of LF/HF and CgA (physiological evaluation) indicated that sympathetic activities were lower in the thin type napkin users than in the thick type napkin users. From these results we concluded that using comfortable napkins have less mental and physiological stress.
