Effects of task and experimenter feedback on the self-reinforcement behavior of internals and externals.

Tested 24 internal and 24 external locus of control Ss on 3 verbal recognition memory tasks. Ss administered self-reinforcement for correct responses on the 1st and 3rd tasks, which had the same difficulty level. The 2nd task was either more or less difficult than the other 2 and was accompanied by E reinforcement. All Ss thus received external evaluation that had variable relevance to their self-evaluation. There were no differences in self-reinforcement base rate (reinforcement rate on the 1st task), but there were several significant and contrasting changes on the 3rd task. Internals attended to both task differences and external evaluation. Externals responded only to evaluation, apparently not attending to task factors. Results are discussed in terms of locus of control and in terms of self-reinforcement behavior. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
