Undergraduate students in sociology (N=59) and psychology (N=50) participated in a study at a large midwestern university to determine if the pattern of attributional assignment, expectancy, performance, and perceived success was different in these two groups of undergraduates. Prior to taking the first of three exams each student was asked how they expected to perform on the test. Before taking exams 2 and 3, they were questioned as to whether, based on the results of the first test, they did anything different in preparing for these exams. The results showed several differences between the two groups in relation to their preparation: of the eight changes in preparation strategies students had to choose from, the two groups differed in the use of five of them. Additionally, task, luck, and effort were the preferred attributions for the psychology students, while knowledge and ability where preferred by sociology students. The study demonstrated that the use of psychology students as representatives of all undergraduates is not justifiable. Nine references. (GLR)
