SEX-DIFFERENCES ON AN ADAPTATION OF THE DIGIT SYMBOL SUBTEST OF THE WECHSLER INTELLIGENCE SCALE FOR CHILDREN .3.

To make the Digit Symbol subtest of the Wechsler Intelligence Scale fo r Children-III more useful in neuropsychological assessment, the measu rement and influence of motor speed and incidental learning on subject s' performance was examined. Analysis indicated that motor speed but n ot incidental learning were significant influences on scores. Statisti cally significant differences between 150 males (M age 12.3 yr., SD=2. 8) and 150 females (M age 12.1 yr., SD=2.7) were obtained for both raw and scaled scores on the Digit Symbol subtest. The implications of th ese gender differences are discussed as a possible example of differen ces in executive function.
