Neuropsychological Study of Spatial Memory Function in Aged and Brain damaged People

本研究的目的是检测老年人和脑损伤人群的记忆功能。特别是，我们研究了视觉空间记忆功能与大脑额叶区域的关系。研究结果先后在日本神经心理学会、日本心理学会等国内会议和国际神经心理学会等国际会议上发表。目前的研究结果涉及(1)考察记忆负荷与脑功能之间的相互关系，(2)考察非常长时间的时间和空间记忆的遗忘过程。(3)考察记忆负荷与大脑半球间交互作用(双边优势效应)之间的关系；(4)考察外周视野的视觉刺激加工。我们还开发了三种神经心理学测验(D-CAT、NNAA和语言流利性测验)，旨在从定量和定性两个方面评估认知功能。数字删除测试(D-CAT)是对注意力和记忆功能的筛选测试。D-CAT已经出版。名古屋大学神经心理评估(NNAA)是对注意力和记忆子功能的深度评估。这项测试也计划很快发布。最后，我们为日本人开发了单词和字母流利性测试。我们准备了正常人的表现标准，旨在用于筛选注意力和工作记忆随年龄增长的函数。

The purpose of this study was to examine the memory function of the aged and brain damaged people. Especially, we examined the visuospatial memory function in relation to the frontal area of the brain. The results were presented at the many domestic conferences, such as Japanese neuropsychological association, Japanese Psychological Association, etc as well as at the international conferences such as the International Neuropsychological Society. The presented research findings related to (1) examination of the interrelations between memory load and brain function, (2) examination of the forgetting processes of the very long-term temporal and spatial memories. (3) examination of the relations between memory load and interhemispheric interaction (bilateral advantage effects), (4) examination of the visual stimulus processing presented at the peripheral visual field.We also developed three kinds of neuropsychological test (D-CAT, NNAA, and verbal fluency tests) which aimed to evaluate cognitive functions in both quantitatively and qualitatively. Digit Cancellation Test (D-CAT) is the screening test for attention and memory function. D-CAT has been published. Nagoya University Neuropsychological Assessment (NNAA) is the deep test for the evaluation of sub function of attention and memory. This test is also scheduled to be published soon. Finally, we developed word and letter fluency tests for Japanese people. We prepared normal people's performance criteria and aim to use for the screening in the evaluation of attention and working memory as a function of aging.
