| Abstract(in English) | We investigated the effects of figure-ground segregation on the blur adaptation. The adaptation stimuli were a set of noise images filtered with a two-dimensional Gaussian filter and changed at 5Hz with different time phase from which a spot area with illusory contour was evoked. Even though the local spatio-temporal characteristics of the retinal image were same in all conditions, the improvement of Landolt visual acuity was significantly large in the spot compared with non-spot and control. However, this improvement disappeared when presentation duration of the spot stimulus was shortened. These results are suggesting that the blur adaptation to the place of figure was promoted compared with other places as ground. |
