Extinction of a conditioned motor response following hypnosis.

The administration of a standard hypnosis induction procedure to 6 randomly assigned experimental Ss resulted in the disappearance of a recently acquired conditioned motor response. When hypnosis was terminated by another standard procedure the CR reappeared. On subsequent trials its appearance followed the usual extinction pattern. An equated control group (6 Ss) gave responses that followed the usual extinction pattern during both a extinction trials. Possible interpretations were considered and suggestions for further study made. (20 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)
