2-A-12 三次元物体認識における空間的処理容量の個人差と視点依存症(2002年度 日本基礎心理学会第21回大会優秀発表賞)

抄録

A large memory set size and a high similarity have been reported to cause view-dependence in 3-D object recognition (Newell, 1998). In this study, we examined whether individual differences in the capacity of spatial information processing (spatial span) relate to this type of view-dependence or not. According to the scoring of a spatial span task (Shah & Miyake, 1996), ten participants with a high spatial span score and ten participants with a low spatial span score were assigned to high and low spatial span groups, respectively. The results indicated that only the low spatial span group showed a view-dependence in the high cognitive load condition of the 3-D object discrimination task. This suggested that individual differences in spatial span could be one of the factors which affect the view-dependence in 3-D object recognition.
