| Research Abstract |
Domain-generality versus domain-specificity is one of the issues of cognitive psychology that receives the most attention. "Domain-generality" refers to the categorizing of a wide range of diverse human mind functions under a small set of psychological principles. In contrast, "domain-specificity" represents the view that the mind consists of different entities whose functioning abides by different sets of rules. In out project, we explored the following three questions : (1)In picture recognition, are there domain-specific mechanisms for asymmetrical confusion effects in which additions are easier to detect than deletions? (2)Are cognitive disorders domain-specific in autistic patients? (3)Are there specific brain mechanisms that underlie domain-specificity?
Our findings are as follows : (1)In picture recognition, we identified asymmetrical confusion effects in which the critical variable is "a strange feeling" (known as "iwakan" in Japanese) in observing changing pictures. (2)In the investigation of the relationship between asymmetric confusion effects and eye movement, we found that additional change manipulation eliciting iwakan increased the number of correctly identified changes in the relevant regions, Meanwhile, deletion change manipulation equally increased viewing the regions empty of objects, but the objects were not correctly identified. (3)Using f-MRI, we found that the feeling of iwakan elicited activation in the specific brain area, especially the posterior cingulate gyrus and insula. (4)The cognitive deficits in autism are considered to be developmentally shaped by interaction between innate dysfunction of intellectual ability and environment, which does not support simple domain-generality or domain-specificity.
