Motor and Sensory Dissociative Phenomena Associated with Induced Catalepsy:A Brief Communication

“…Although objectively nothing is wrong with the arm, the person perceives the arm as stiff and is not able to bend it. Some evidence is also found for the idea that sensory information processing changes during catalepsy (Diehl et al, 1989). For example, a PET study found a state of total body catalepsy to be related to a deactivation of primary visual and (less significantly) primary auditory areas.…”

“…Apart from the stress context, the phenomenon of catalepsy can be elicited in a hypnotic context (Diehl, Meyer, Ulrich, & Meinig, 1989;Grond, Pawlik, Walter, Lesch, & Heiss, 1995;Sacerdote, 1970aSacerdote, , 1970b, which might provide a useful research paradigm for the study of motor and sensory dissociative experiences. However, in most studies in which hypnotic techniques are applied to elicit catalepsy, it remains unclear how catalepsy was induced.…”
