Abstract
This study tested Phares, Wilson, and Klyver's (1971) hypothesis that locus of control differences are unimportant in a situation which provides very explicit cues arousing specific expectancies regarding the locus of blame for poor performance. Two hundred and seventeen undergraduate students (134 men and 83 women) completed Rotter's I-E Scale as part of classwork in midsemester. During the last week of the semester they were routinely administered a questionnaire containing items on course evaluation, instructor evaluation, and expected grade. Expected grade was significantly correlated with ratings on several course evaluation and instructor evaluation items for internals and externals in the male, female, and total samples. However, these correlations were not significantly different for internals and externals in each sample. These results provided strong empirical support for the tested hypothesis.
