Abstract

This study predicted that sex differences in performance can occur where the sense of touch serves as vision, and that the position of the test array may significantly affect performance. Sixty-four college undergraduates (32 males and 32 females), with ages ranging from 18-27 (M = 20.06, SD = 1.82) were recruited from the psychology subject pool of Eastern Illinois University for participation. Apparatus consisted of templates with raised line drawings of tilted jars containing water drawn on them. The subjects were blindfolded and instructed to interpret four jar drawings at a time. The task consisted of identifying the jar with the correct water line. All subjects participated in 8 trials. Half were tested on an upright test array, and the rest on an array that was tilted. The data were analyzed using a 2 X 2 X 4 (Gender X Position of Test Array X Angle of Jar) ANOVA. The results indicated that gender was significantly related to performance of the task, and that males performed better than females did, F (1,180) = 8.1, p<0.01, while the position of the test array was not, F (1,180) = .83, p>0.37.
