When we see some moving figures, we have perceptual as well as affective impressions. Our previous investigation (Yoshida, et al., 2001) has demonstrated that moving dots induce affective impressions. In this study, we changed three physical variables: wave-form, amplitude change and speed of moving dots, and examined affective effects induced by these variables using the Semantic Differential method. The factor analysis revealed three main factors: activity, evaluation and "living or animacy" impression. And physical feature of stimuli influenced affective impression complexly. Moving dots generated stronger impression of living objects than the still paths. These results suggest that moving objects can give us particular affective effects including "living or animacy". Why do we feel that moving geometrical figures seem to be alive? Tremoulet and Feldman (2000) suggested that when we perceived some forces other than physical forces such as gravity, we feel "living or animacy" instead of physical forces. This study was designed to re-examine the living impressions in the conditions similar to Yoshida et al. (2001) excepting that inclining line looking like slope, was added When dot's amplitude is decreasing in condition that inclining line looks like an uphill, the move can be explained physically. But, if dot's amplitude is increasing, because the move can't be explained physically, expect that impression of "living or animacy" is larger. We use three independent variables, line's inclination, dot's speed and it's amplitude, and investigate that these factors affect to "living or animacy" impression.
