| Outline of Final Research Achievements |
In this research project, an aberrant sensory precision account, which is one of the normative theories of psychiatric disorders, was tested utilizing a recurrent neural network model. In particular, we focused on the effects of changes in estimated sensory precision on adaptive behavior via prediction error minimization mechanisms. To distinguish dysfunction at behavioral and network level, we employed a humanoid robot driven by the neural network and observed ball-playing interactions with a human experimenter.
The experimental results demonstrated that both increased and decreased sensory precision induced abnormal behaviors such as freezing and repetitive behaviors. These results may provide a system level explanation of different types of behavioral abnormality in psychiatric diseases.
