Verbal/visual processing for males disabled in print acquisition

Fourteen males disabled in print acquisition were studied over time to determine their patterns of verbal and spatial processing. Comparing results of WISC-R and WAIS scales using a Bonferroni correction for t-values, it was found that the Similarities subtest scores significantly increased while the Vocabulary subtest scores and Acquired Knowledge category significantly decreased. Hemispheric specialization was suggested as a possible cause for differences in verbal and nonverbal processing.
