A03Cognition and sociality Understanding of neural basis of thought disorder in psychiatric disorders and development of assistance for them.
Thought disorder in psychiatric disorders manifests itself in various ways such as difficulties in category formation, abstraction and inference. Although healthy adults can flexibly change the level of abstraction and inference according to context, patients with psychiatric disorders typically have impairments of these abilities, which lead to social dysfunction. Until recently, we have to limit the category of brain region to investigate impairments of category formation, abstraction. However, recent advance in neuroimaging analysis allows us to study numerous category and whole brain comprehensively. Here, we aim to elucidate neural basis of impairments in category formation, abstraction and inference in psychiatric disorders. In addition, in collaboration with artificial intelligence researchers, we try to establish computational model of thought disorder.
