| Outline of Final Research Achievements |
The interpolation and reconstruction of fragmented visual information during the cognitive process is a very important feature of visual cognition. To elucidate the mechanism of visual interpolation, this study evaluated the importance of residual information for the fragmented-letter recognition, and proposed a least-distance connection model. The preference of connecting scattered information was also investigated. An fMRI experiment was conducted to locate the brain areas involved in the visual interpolation. A simple measurement system using touch panels or tablets was developed to easily measure the recognition ability for fragmented letters. The relation between visual interpolation ability and aging was also studied to explore the possibility of early detection of cognitive impairments.
