This study examined the human shape’s effects on the visual working memory for color schemes in a recognition task using event related potential (ERP). The experiment confirmed which parts condition (body region, geometric figure) and layout condition (human, disordered) affected the color memory. Regardless of the parts condition, color schemes with human layouts were more correctly memorized. Similarly, the P3 amplitude of ERP in the parietal regions, which decreases with the memory load, were significantly larger in figures with human layouts, regardless of the parts. These results suggest that the layout has a major impact on color scheme memory.

This study aimed to explore the effect of human hand touch on motor learning. Participants pushed a ball toward a target distance by elbow flexion. Thirty-eight healthy participants attempted the task as pre-test using a dominant and non-dominant arm, and then the non-dominant arm was trained. The following day, a post-test was performed using both arms. Participants were randomly divided into three groups based on training conditions: one group received knowledge of results (KR group), Touch group received KR and the non-dominant ventral upper arm was touched by another person, and Control group received no additional conditions. Performance progressively improved during training session in the KR and Touch groups; however, only the Touch group showed post-test improvement. This result suggested that a human hand touch facilitates motor learning.

The purpose of this study was to investigate the changes of salty taste sensitivity (STS) during the physical education (P.E.) swim class in outdoor, summer. Eight healthy young males (age: 16 years) were volunteered to this investigation and swam (approximate 400 m for 70 minutes) in July (temperature: 31.2 ± 0.6 ℃ ). Participant’s STS, urinary electrolyte, ration of dehydration and the degree of salty appetite (DSA) were measured before and after P.E. (respectively, Pre and Post). DSA at Post was significantly higher than that of Pre. STS, urinary Na / Cr and urinary Cl / Cr at Post were significantly lower than that of Pre. STS at Post significantly increased even if that ration of dehydration (0.45 ± 0.20 %) was not enough to the level of concern in summer.
