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.

Twin method is a traditional way to investigate genetic and environmental (shared and nonshared) influences on human behavior. The number of publicity using twin method is continuously growing recently which robustly shows substantial genetic contribution to almost any aspects of psychological individual differences. Molecular biological techniques and multivariate statistical method called structural equation modeling (SEM) provide several generalizable findings such as very small effect of each single gene, significant genetic mediation in phenotypic correlation, heritability increase in IQ from infancy to young adulthood, and socially important gene x environment interaction. Discordant identical twin method has a powerful possibility to investigate epigenetics.

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.

As most of the corticospinal fibers cross over to the contralateral side, the right side of the body is controlled by the left primary motor cortex, while the left side of the body is controlled by the right primary motor cortex. However, because callosal connections between the two hemispheres and ipsilateral corticospinal pathways convey the same information to bilateral homologous muscles, interference can occur between the left and the right motor system when we use bilateral hand simultaneously. This interference could work as a cost-effective measure in symmetric movements and a resource-demanding measure in asymmetric movement. In this paper, I discuss how the brain represents cost-effective and resource-demanding bimanual interaction.

Twin research has been of fundamental importance to the field of human genetics. There are two phases to twin studies: 1) a biological interest for twins, and 2) usefulness of schemes using twin characteristics. In this review, I outline the two phases of twin studies, related to both genome and epigenome studies, and discuss the potential expansion of twin studies in physiological anthropology in the near future.

Emerging research field of music and neuroscience has attracted much interest recently on musician's brain and behavior. Nevertheless, motor control mechanisms underlying skilled musical performance are still largely unknown. In this paper, I review recent studies on surface electromyographic (EMG) activity of the wrist flexor and extensor muscles in the winner of a contest to find the world's fastest drummer (WFD). By showing the wrist muscle activity of the WFD, I explain possible neuromuscular mechanisms underlying the exceptional musical performance.

This paper is an attempt to deal with the origins and formation of the Japanese language, in the light of mostly linguistic aspects of the neighboring languages, such as Old Korean, Old Chinese, Proto-Austronesian, and some archeological aspects. This notion is also based on a linguistic theory that the Japanese is formed through time with language contacts with the neighboring languages mentioned above. This also discusses the particular aspects of language contact of each language and language family in order to suggest that Japanese has been formed by language contacts with those languages.
