Two different theories of the cognitive processes involved in rating performance were compared by Nathan and Lord in 1983. These theories comprised Bormans 1978 traditional model of dimensional schemata and Feldmans 1981 cognitive categorization theory. To further explore the role of each in the process of performance appraisal over time, participants in the present study were presented with two different video-tapes of a lecturing college instructor. One half of the participants initially viewed a tape exhibiting primarily good lecture behaviors and two days later viewed a videotape containing mostly poor performance behaviors. The order of videotape presentation was manipulated so that the remaining participants viewed the tapes in reverse order. Subsequently, subjects appraised the lecturers performance on a series of Likert rating scales and also completed a questionnaire examining their ability to recall specific performance behaviors. These measures revealed partial support for both theories. In general, the performance ratings lent support to the traditional model while cognitive categorization was corroborated in the recognition memory task.
