Abstract(in Japanese) (See Japanese page)
Abstract(in English) Mental representations of faces are investigated by using schematic faces and faces synthesized by computer graphics. Similarity spaces of those faces yielded by multidimensional scaling are compared with the principal component spaces on attribute values or Gauss-filtered images of these faces. A comparison to similarity spaces of internal representations of artificial neural networks that learned identity transformations of those faces is also made. It is suggested that faces are encoded in a multidimensional space, whose dimensions represent configural features, and that spatial representations are formed by a process that resembles principal component analysis, furthermore, it was shown that the process can be simulated by simple networks.
