Outline of Final Research Achievements

This study investigated 1) how our brain segments object image from the background and 2) how it maintain the image. Previous research assumed importance of spatial information for the segmentation process, and some researchers argued that images of overlapped objects are automatically integrated into one image, because they shares the location. I confirmed the propose, further, examined the neural mechanism using Event Related Potential.
In addition, I revealed that visual working memory, a cognitive function to retain object image, have separated storage capacities for color and orientation features.
