鳥獣人物戯画絵巻より得た図版の特性ならびに神経心理検査への応用の可能性に関する研究

Abstract

Certain minor cognitive deficits cannot be detected by conventional neuropsychological tests. Moreover, conventional tests can only partially examine higher cognitive functioning, therefore complicated test batteries must be used to identify minor cognitive deficits. The Choju-Giga Test (CGT), developed by Minoshita et al. (2004), was designed to fill the gap in testing. Three pictures cards, 1, 2, and 3, are used for the CGT. A test of the effectiveness of the CGT was conducted in this study. Card 1 and card 2 were regarded by all participants as pictures which portray informal situations such as family, relatives, or friends. However, the theme of ‘organized relationship’ was assigned to card 3 by a quarter of all participants. The number of words used in explaining card 3 was significantly more than for card 1, and there was also a significant difference in the position of characters in the pictures assigned by participants only to card 3.Paul et al. (2004) hypothesized that TAT pictures for neuropsychological test must include complex social situations. This study suggests however that card 3 is more effective than the other 2 cards in detecting subtle cognitive deficits.
