Pavlovian galvanic skin response conditioning in overweight and normal weight women.

20 overweight and 20 normal weight female undergraduates underwent habituation, classical conditioning, and extinction of the GSR. Overweight Ss were consistently more responsive to the CS (tone) during all 3 phases of the study and were somewhat more responsive to the UCS (shock). Rates of response attenuation and enhancement, however, were not different during any phase. Results are generally consistent with research which demonstrates that overweight Ss are more externally stimulus bound than normals. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
