Abstract

The purpose of this paper was to study genetically in the process of being established our perceptual constancy of objects and GegenstandsbewuBtsein and to try to clarify how they interact. Two Korean girls' response tendency and Kinaesthese were observed for two years (Seok-joo) and one and a half year(Deok-joo), respectively. The observed data were analysed in terms of the constitution of object permanence concept (Piaget) and the occurrence of the perception of shape constancy. The relationship between the two were discussed and the intervention of a certain cognitive activity into the process of perception was supported. Theoretical implication was discussed within the framework of Helmholtz's unconscious inference, Piaget's perceptual activity, and Husserl's Konstituion.
