Comparison the Performance of Children with and without learning disorders in The Wechsler Intelligence Scale for Children-Revised

This research aimed to Compare the Performance of Children with and without learning disorders in The Wechsler Intelligence Scale for Children-Revised. The research method was Ex Post Facto Research design. Thus by multistage clustering sampling, 45 students with learning disorders and 45 students without learning disorders completed demoghraphical data questionnaire and The Wechsler Intelligence Scale for Children-Revised. Data analysed by independent t test, one-way analysis of variance and multivariate analysis of variance.There was statistically significant difference between Children with and without learning disorders in standardized total scores of the WISC-R, verbal subscale and performance subscale. pure power (Eta2) of WISC-R’s verbal subscale and performance subscale for differentiation the two groups was equivalent with 0/84 and 0/56 respectively. Also, performance of the two groups was statistically significant different among subscales of information, mathematics, digit span, Picture arrangement, coding and these scales have favorite power in differentiation the two groups. Thus, can be stated that The Wechsler Intelligence Scale for Children-Revised applicable for differential diagnosis the Children with and without learning disorders and via provision of WISC-R based learning disorders diagnostic checklist especially by focusing on five scales of information, mathematics, digit span, Picture arrangement, coding can diagnosis the learning disorders
