Motor imagery in hypnosis: accuracy and duration of motor imagery in waking and hypnotic states.

This study assessed response times and accuracy of motor imagery in waking and hypnotic states and to related responses to hypnotic experiences. The Vividness of Motor Imagery Questionnaire (VMIQ) was administered to 47 participants. A mental walking task was then performed in the waking state. In hypnosis, the same task was included within an imaginary journey after a hypnotic induction. An interaction effect showed for condition (waking vs. hypnotic) and distances. The further the participants had to walk in imagination, the longer they took. For all combinations, participants took significantly longer in hypnosis (p < .001) and were significantly less accurate in hypnosis in reproducing the difference between the different distances (p < .001). Results appear to show a relationship between motor imagery and hypnotic responding and support a state-trait conception of imagery.
