| Abstract: | Investigated the conditions under which speech influences the speed of a tapping response in 48 schizophrenics and 48 nonschizophrenics. Ss verbalized 3 words ("goads") under varied pretask instructions (minimal and slow instructions) and 2 sources of delivery (self-delivered "internal" verbalizations and other-delivered "external" verbalizations). Results indicate that all groups inhibited speed of tapping for a slow instruction. The schizophrenics under the internal goad condition inhibited response as well as the control group; under the external goad condition these patients were less able to inhibit response. For the minimal instruction condition the schizophrenics responded to the meaning inherent in the goads faster and slower for the internal but not the external goad condition. The converse was true for the control group. (16 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
