Human movement (M) responses to the Rorschach are related to cognitive sophistication, creativity, and empathy. Recent studies also link Ms to EEG-mu suppression, an index of mirroring activity in the brain. In this article, we further investigate the link between Ms and mu suppression by testing some clinical interpretative distinctions. Previously collected EEG data recorded during the administration of the Rorschach were reanalyzed. We hypothesized that (a) among several responses investigated, only M would be associated with mu suppression, and (b) Ms with active movement, ordinary form quality, or whole human figures would be most strongly associated with mu suppression. Hypothesis 1 was fully confirmed, thus supporting that the traditional interpretation of M has a neurobiological foundation. Hypothesis 2 was partially confirmed; that is, active Ms were associated with mu suppression more strongly than passive Ms (p
