Compared 2 models of the cognitive processes underlying performance ratings: a traditional model outlined by W. C. Borman (see record 1980-26801-001), and a cognitive categorization model proposed by J. M. Feldman (see record 1981-24524-001). To distinguish these 2 models, 120 college students were shown 1 of 2 videotapes of a college lecturer in which 3 of 5 dimensions of performance were manipulated to be opposite to that of the lecturer's overall performance. Ratings were made either immediately after viewing the videotape or 2 days later. Results indicate that the traditional model was appropriate for describing the rating process in both the immediate and the delayed rating conditions. However, a large halo effect was also found that was consistent with the categorization model despite conditions designed to minimize the likelihood of halo. Additional effects of cognitive categorization included a tendency to make errors in later recall of lecturing incidents consistent with Ss' general impression.
