The purpose of this study was to examine the impact of a specific subtype of dyslexia, namely phonological processing, on performance and the results of ability on IQ testing. Twenty-two records from a learning center in southern New Jersey were used for data in this study. The sample consisted of 12 male and 10 female children's charts. These children were tested at the learning center in 2005. The age range of the sample is six to eleven years-old. There is no identification of any kind in this study. The information used from the charts included: full scale IQ scores from the Weschler Intelligence Test for Children- Fourth Edition and 3 subtest scores from The Comprehensive Test of Phonological Processing. The 3 subtest scores used were: Elision, Rapid Color Naming, and Rapid Object Naming. A correlation was done between the all 3 subtests of the CTOPP and the full scale score of the WISC-IV. Results showed a significant correlation at the 0.05 level between the Elision subtest of the CTOPP and the full scale score of the WISC-IV. This study concluded that there is a correlation between poor phonological processing scores and performance on IQ tests.
