Abstract(in Japanese) (See Japanese page)
Abstract(in English) The Differential Outcomes Effect (facilitative effect on discrimination learning when each of two discriminative stimuli is correlated with a particular outcome) occurs with human and non-human subjects' learning. DOE includes two steps of action selection processes, stimulus to reward expectation and reward expectation to action. Many medial prefrontal neurons represented either the former step or the latter one. It suggests that the medial prefrontal cortex plays a crucial role in DOE. Utilization of the two-step processes may enhance performance in cognitive tasks for patients with mental retardation except Parkinsonism or schizophrenia in those the DOE critical steps may be impaired.
