The process what the visual system grasps the object is learning the characteristics of lines, bodies, colors, actions, etc. These special characteristics of visual system have relationship with molding elements which are visual and cognitive factors in art-expression activities. Therefore the purpose of this study is researching the relationship between molding elements and special attribute of visual system. The methods of this study are searching books which had relationship with visual system and molding elements - cognitive psychology, nerval psychology, visual psychology, general psychology - ordinarily. I find following results through the study : First, form, color, space, movement which are special attributes of visual system and form, color, space, movement in molding elements have same meaning. So the understand of visual system provides the physiological basis. Second, molding elements can be considered as physiological and scientific visual perception elements which has relationship with visual system not ambiguous art expressional factor. Third, the brain's visual cells which control form, color, space, movement - the special attribute of visual system are individual and successive. So we can know the molding elements is also individual and successive. For that reason we should adopt the same theory in the molding element's teaching contents and methods. Fourth, the visual system's process that controls shape, color, surface, depth is not similar to the visual system's process that controls movements. Consequently we can figure out that it is very different to make perception shape, color, quality, space and to make perception movements.
