Wechsler Adult Intelligence Scale-Third Edition Picture Arrangement subtest: impact of vertical administration.
We compared the Wechsler Adult Intelligence Scale-Third Edition Picture Arrangement (PA) scores via standard administration (SA) or vertical administration (VA). Fifty-seven college students were assigned to one of two conditions. Thirty SAs had means for age, education, and American College Testing (ACT) of 19.47 (SD = 1.14), 13.60 (SD = 1.16), and 22.27 (SD = 2.65), respectively. Twenty-seven VAs had means for age, education, and ACT of 21.26 years (SD = 2.99), 14.44 years (SD = .93), and 22.63 years (SD = 3.79), respectively. An analysis of covariance revealed nonsignificant results for age and education, Fs < 1, but a significant difference emerged for type of administration, F(1, 53) = 4.42, p < .05. SA (M = 10.33, SD = 2.97) yielded a significantly higher mean PA score than did VA (M = 8.30, SD = 2.84).
