Abstract (in Japanese) (See Japanese page) 
(in English) A radial expanding flow having a linear positive speed gradient is perceived as a rigid object approaching to the observer, while that having no or reduced speed gradient is perceived as a non-rigid, 2-dimensionally deforming object. (De Bruyn and Orban, 1990). We tested elementary school aged children (1-3 graders and 4-6 graders) and adults to examine the development of the rigidity perception. The results suggest that 4-6 graders (but not 1-3 graders) and adults have similar properties in perceiving rigidity from radial expanding flow with speed gradient.
