14 daydreaming Ss were compared to 14 nondaydreaming Ss according to the results obtained from psychometric tests and school questionnaires. The daydreamers' scores on the Bender-Gestalt test and on the performance section of the WISC were appreciably more variable than those of the nondaydreamers. This implies heterogeneity within the group of daydreamers. According to their classroom teachers, daydreamers were more likely to have problems with flexibility, distraction, ability to persist at a task, peer relations, and arithmetic. These findings suggest that daydreaming does not occur as an isolated entity.

This report demonstrates the discrepancy that can occur between clinical and test evaluations of competence. It presents retrospective examination of 35 assessments of competence performed on 24 subjects by a multidisciplinary competency panel. The findings of the panel are compared with the subjects' results on the Cognitive Competency Test and on the Mini-Mental State Examination. The results show that the multidisciplinary competency panel will more often find subjects competent than indicated by their psychometric test scores. A process approach to the use of tests is recommended. Reliance on tests to decide the outcome of difficult cases does not appear to be warranted.
