Research has produced mixed results in evaluating whether people are influenced more by computer output than by other information. The present study examined how teachers' perceptions of psychological reports differ when the reports are identified as being produced by a computer program or by a school psychologist. Subjects were 40 experienced teachers and 55 teacher trainees enrolled in workshops relating to psychological reports. Results revealed a significant effect of report source on subjects' evaluation of the report. Computer reports were rated significantly higher than psychologist reports. Evaluation of the reports was also affected by the number of errors the subject reported seeing. Two or more errors reported led to significantly lower ratings. Gender, amount of teaching experience, number of testing courses, and amount of computer experience were not related to report ratings. Contains 10 references. (Author)
