When we discriminate the weight of the two balls of the size which can be hand held, if the lightness of two balls is different, we may judge that the weight of two balls differs, even if two balls are equal weight. The weight of the balls is distinguished according to not only muscle perception by the hefting them but also information of the balls got from auditory perception and visual perception. In addition to this, the weight of the ball is discriminated in the brain, comparing information got with a knowledge stored by one's experience. By individuality and scene, the information which decides the weight is different. In the weight discrimination, which information is a decision maker, is different by individual and scene. There are manifold of perceptual processes in the weight sensation. In this paper, we will propose the new categorization method that classify the some perceptual characteristics, and then subjects are categorized into some perceptual characteristics such as Group (α): Information from visual perception is the superiority, Group (β): Information from both visual perception and muscle perception is utilized, Group (γ): Information from muscle perception is the superiority.
