| Outline of Final Research Achievements |
In this study, we aimed at clarifying the effects of repeatedly performed or observed actions on preference evaluation for visually presented action stimuli (visuomotor mere exposure effect; visuomotor MEE) and identifying brain regions involved in the visuomotor MEE by using fMRI. The behavioral data showed that increases in preference rating for the imitated stimuli were significantly larger than those for the control stimuli. An analysis of brain activity during the pre- and post-preference rating sessions revealed activation in posterior cingulate cortex (PCC), caudate nucleus, orbitofrontal cortex (OFC). Additionally, we found that signals in IPL decreased in correlation with the repetition of imitation and that the deactivation correlated with the effect size of MEE. Our results suggest that repeated motor imitation elicits MEE for visuomotor-associated stimuli and that the value-related network and the mirror neuron system are involved in the phenomenon of visuomotor MEE.
