Abstract: | Abstract: The purpose of this study was to examine 5‐month‐old infant's sensitivity to a shading cue with radial motion. Our stimuli were radially expanding or contracting circles with vertical or horizontal shadings. We tested infants’ preference for vertical (top‐ and bottom‐lit) and horizontal (left‐ and right‐lit) shadings. The results indicate that infants tested with the vertical shading showed significant preference for the top‐lit shading, whereas infants tested with the horizontal shading did not show any significant preference. The fact that the significant preference was observed only in the vertical shading condition suggests that 5‐month‐old infants might use shading information on the basis of the “light‐from‐above assumption.” We revealed that even 5‐month‐old infants are sensitive to shading information when they are exposed to shading stimuli with radial motion. |
