Background & Objectives : This study was divided into two parts. The first experiment portion compared the phonological processing skills of school-aged children with cerebral palsy with the skills of younger language-matched children. Based on the results of the first experiment, the second experiment attempted to explore the effect of two different kinds of phonological processing interventions on reading skills.
Methods: Twenty school-aged children with cerebral palsy, who were living in Seoul and Gyeonggi-do, and twenty language-matched, typical children (age 6) participated in the first experiment. The participants were tested with phonological processing tasks(phonological awareness, phonological working memory). The difference between the two groups and its impact on word recognition were analyzed. In the second experiment, each group of ten people were assigned to a phonological awareness-centered training program and a phonological working memory-centered training program. They were administered phonological processing tasks and word recognition skills in order to examine the effects of intervention.
Results: The group of school-aged children with cerebral palsy performed significantly lower in two types of phonological processing tasks and word recognition than the language-matched children. In addition, the phonological working memory accounted for only 25% of the variance in word recognition. Both phonological awareness intervention and phonological working memory intervention increased the rate of correct responses. The phonological working memory-centered training group improved regardless of the intervention type. On the other hand, the phonological awareness-centered training groups improved only on the trained task.
Discussion & Conclusion: Even though all of the children who received phonological processing training made significant gains in word recognition, the phonological working memory intervention seemed to be more effective for improving word recognition skills for school-aged children with cerebral palsy.
