The effects of neurological priming on the Rorschach: A pilot experiment on the human movement response

This article introduces a new scientific paradigm that might allow the investigation of the neurological correlates of the Rorschach test without using expensive and time consuming tools such as the fMRI or the EEG. Based on the literature on the Mozart effect, we anticipated that preactivation of a given brain network before exposure to the Rorschach cards would associate with the increased production of responses (or determinants) presumed to be associated with that same network. To pilot test this hypothesis, we focused on the postulated link between human movement (M) responses and mirror neuron system (MNS) activity, and investigated whether preactivation of the MNS would associate with the increased production of M responses. Specifically, 30 students were administered a subset of Rorschach cards immediately after watching three short videos aimed at activating the MNS at three different levels (no/low/high activation). Although no statistically significant differences among the three conditions were found, a linear trend in the expected direction (p = .107), with medium effect size (η2 = .087) was observed. In addition to providing information on the M response, this article introduces a new scientific paradigm to investigate the neurological correlates of the Rorschach.
