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

本研究旨在探讨老年人和脑损伤者的记忆功能。特别是，我们研究了视觉空间记忆功能与大脑额叶区的关系。研究结果在许多国内会议上发表，如日本神经心理学协会，日本心理学协会等，以及国际会议，如国际神经心理学会。研究结果涉及：（1）记忆负荷与脑功能之间的相互关系的检查，（2）检查的时间和空间的非常长期的记忆遗忘过程。(3)（4）周边视野对视觉刺激的加工过程，以及三种神经心理学测验（D-CAT、NNAA和言语流畅性测验）对认知功能的定量和定性评价。数字消除测验（D-CAT）是一种用于检测注意力和记忆功能的筛查性测验。D-CAT已发布。名古屋大学神经心理学评定量表（NNAA）是对注意和记忆亚功能进行评价的深度测验。这项测试也计划很快公布。最后，我们为日本人开发了单词和字母流畅性测试。我们准备了正常人的性能标准，旨在用于筛选在评估的注意力和工作记忆作为一个功能的老化。

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.
