McCarthy and WISC-R correlations with WRAT achievement scores.
The relationships between the McCarthy General Cognitive Index and WISC-R Full Scale IQ with the Wide Range Achievement Test Reading scores were explored with a sample of 20 educable mentally retarded (M age = 7.10) and 20 learning disabled (M age = 8.1) children. Wide Range Achievement Test scores did not correlate significantly with the WISC-R and McCarthy scores for the retarded sample, while substantial correlations were found for the learning disabled group. Analysis indicated that the McCarthy and WISC-R were positively and equally related to the Wide Range Achievement Test Reading section. Implications of these findings are discussed.
