The Performance of Preschoolers with Speech Language Disorders on the McCarthy Scales of Children's Abilities
The McCarthy Scales of Children's Abilities (MSCA) was used to evaluate the performance of preschool children with speech/language disorders. Preschoolers were screened first for normal intelligence using the Performance scale of the Wechsler Preschool and Primary Scale of Intelligence (WPPSI). Preschoolers with speech/language disorders had significantly lower scores on all scales of the MSCA (Verbal, Perceptual/Performance, Quantitative, and Memory), except the Motor scale. They also had an average 20-point lower GCI than the control children. An analysis of the scores of the speech/language group on subtests revealed difficulty in short-term auditory memory skills but not in short-term visual memory skills. Deficits in categorical thinking skills and verbal expression skills were also evident. Characterization of learning disabilities in preschoolers with speech/language disorders is discussed.
