title: Coding A and coding B of the WISC are not equivalent tasks.
abstract: WISC Coding A and Coding B were administered to 50 subjects with minimal brain dysfunction and 75 controls whose ages ranged from 7 yr., 8 mo. and 0 days to 8 yr., 3 mo. and 30 days, with half of each group above 8 and half below. Standard scores showed significant differences between Coding A and Coding B suggesting that the two tasks are not equivalent forms. These differences suggested that separate information-processing modes related to hemispheric dominance may be present. Coding probably should not be used in calculating IQs but Coding B should be retained and separately utilized because it is directly related to symbol learning.
