Three third-grade, three sixth-grade, and three adult female examiners tested 108 kindergarten and third-grade girls, half of whom were familiar to them, on three individually administered measures. No differences in performance on any measure as a function of familiarity were found at either grade level. No differences by examiners of different ages were noted on the numerical test, while differences in favor of the third grade examiners were found on the classification test (p = .07, n.s.) and on the Wechsler Intelligence Scale for Children (WISC) vocabulary subtest (p = .01). The effects of interpersonal and task-related variables were discussed, along with implications for peer instruction. (Author) (37pp.)
