Outline of Final Research Achievements |
The previous study suggested that there was a function called “closer” which was supposed to weaken negative effects of visual input when one generated mental images. The goal of the present study was to establish the “closer”. In this study, brain activity was recorded when participants were generating mental images while observing a stimulus which had distracting effects for mental imagery. Results showed that activity within a part of low-level visual cortex lowered. The results suggests that the “closer” suppresses the vision to protect the generating process of mental images from being exposed to distracting effects of incoming visual input.
