Research Abstract |
The present study examined the effects of surface feature or contour information of objects on several phenomena related to motion perception. Firstly, we investigated whether and how abrupt change in the color of a previewed mask affects the mask preview effect, where object substitution masking is largely attenuated by mask preview. Wefound that abruptly changing the mask color at the target onset disrupted mask preview effect, that is, substitution masking was reinstated. Secondly, we examined the effect of contour blur of an approaching object on its estimated time-to-contact (TTC). We manipulated the degreeof blur and measured TTC estimation for a circular stimulus with a sharp or blurred edge. The results showed that estimated TTC increased with increasing the degree of blur
