Outline of Final Research Achievements

The main function of the visual system is to recognize "what it is" and "where it is" from retinal images. Especially, estimating size and length of object is extremely important to recognizing depth and structure of the space. Recently, Hisakata, Nishida & Johnston (2015) found that perceived size or distance between two objects shrank after adaptation to dense texture. In this study, I examined basic spatio-temporal characteristic of the aftereffect. I showed that the aftereffect could not be explained by the size adaptation. Also, the effect occurred at binocular processing stage.
