WISC, Wechsler Intelligence Scale for Children, Intelligence tests
As an effort to compensate for a previously reported female examiner effect, four male examiners spent 15 minutes with each of 16 male and 16 female third grade children prior to WISC administrations. Four female examiners administered the WISC to equal numbers of male and female children. No female examiners effects were found. Under these conditions male and female examiners obtained similar Full Scale WISC IQ scores, although the male children had higher full scale scores. PIQ was significantly higher that VIQ and girls evidenced the greatest VIQ-PIQ difference. These results are congruent with literature that implicates both sex of examiner and pretest examiner effects on intelligence testing. Pretest exposure reduces anxiety with adult males, creates a "good" relationship, and provides positive social reinforcement. These variables are felt to have contributed to the increase in IQs obtained by the male examiners.
