Experimental analysis and computational simulation of the attribution of own actions by the multiple forward models

Human cognitive mechanisms have been studied for designing user-friendly interface. One of the key issues is the attribution of own actions to the intention of self or others. It is known that patients with schizophrenia who sometimes attribute their own actions to the intentions of others may perceive themselves as causing events which they do not in fact control, when they feel they are in voluntary movement. In this study, we administered similar experiments to normal subjects. We also conducted computational simulations through extending the multiple forward models, which successfully described the experimental results.
