既知顔と未知顔の記憶表象(顔を見る,顔を思う,顔をつくる-顔知覚研究の行方-,2005年度 第2回フォーラム)

抄録

Previous research has shown a large difference between recognition for familiar and unfamiliar faces. We are surprisingly good at recognizing familiar faces, while we are poor at matching images of unfamiliar faces. It is known too that an advantage for matching the internal features of familiar faces in contrast to an advantage for the external features of unfamiliar faces. However it is not clear how facial representation changed as the faces became more familiar. Two experiments were conducted to examine how difference there is between familiar and unfamiliar facial representations. Experiment 1 showed familiar faces differ from unfamiliar faces qualitatively in mental representation. Experiment 2 suggested the distinctiveness of internal features is exaggerated in memory representations of familiar faces. These results suggest that one of the differences between familiar and unfamiliar faces is the distinctiveness of inner features in mental representation.
