| Outline of Final Research Achievements |
(1) We conducted a series of studies in which healthy Japanese participants were administered the gray scales task, a test of spatial attention developed in Australia that is easy to administer and quantify. As a result, we found that Japanese participants also had a leftward bias in the horizontal direction and an upward bias in the vertical direction, and that these biases were not affected by handedness or aging. (2) Although it has been pointed out that difficulty in discriminating between left and right is related to damage to the left parietal lobe, we found that this was actually observed in healthy participants to a certain extent and was not affected by gender or handedness. (3) We examined methods for measuring handedness and footedness using questionnaires and performance tasks. (4) We conducted an interview survey on social behavior disorders of brain-injured individuals and their families.

| Academic Significance and Societal Importance of the Research Achievements |
今回実施した研究はいずれも健康なボランティアを対象とした基礎的研究であるが、それらから得られた知見は、高次脳機能の神経基盤を解明する上での重要な手がかりとなる。また、臨床の現場では障害の有無や程度の検討に必要な基準データとして活用することが期待される。
