The correlation between the types of geometric transformation (i. e., identical, congruent, affine, projective and topological) of stimuli and those of stroboscopic motion therefrom was investigated under various temporal conditions (i. e., stimulus durations of two stimuli and SOAs between them). The results were as follows. (1) Four kinds of seeing motion were found; i. e., translation, plastic deformation, rotations in 3-dimensional space and on 2-dimensional plane. (2) Some of these types of motion were uniquely corresponded to a specific geometric transformation but some were not. Translation corresponded to identity transformation, while plastic deformation corresponded to affine or to topological transformation. Plastic deformation and rotations also corresponded to projective or to congruent transformation. (3) There was no effect of stimulus durations in the case of unique correspondence. In other cases, rotations, either 2- or 3-dimensional, were relatively superior to plastic deformation as the duration increased.
