The Effectiveness of Developmental Therapies (VAK Learning Style) with Cognitive Information Processing Approach in Treatment of Cognitive Dyslexia

The purpose of the present study is to determine the effectiveness of developmental therapies based on cognitive information processing approach on improvement of dyslexia in 7 to 9 years old children with learning disabilities in Alborz province.

The method of this research is pre-test; post-test, with control group. The statistical population of this study consists of 60 persons, 30 of whom were placed in treatment group and 30 were placed in the control group. Prior to treatment interventions, IQ was assessed using Wechsler IV test, signs and symptoms of dyslexia was assessed with Cattell Horn Carrollchr('39')s developmental therapies approach, ISHINR and cognitive information processing and learning style of students, parents, therapists and teachers was measured and evaluated using VAK Questionnaire. Then the students were divided into three separate groups of visual, auditory and kinesthetic based on their gender, age, educational level, learning style and considering the study goal. Thereafter, the training sessions were held within two months for these three groups. The students attended 15 ninety-minute training sessions along with their parents, while the control group did not receive any training.  

The data were analyzed using multivariate analysis of variance (MANOVA) method and the results showed that there is a significant difference (5%) between all of the three treatments groups in comparison with the control group, so all the three treatments methods are effective.

Developmental therapies (VAK learning style) utilizing cognitive information-processing approach are effective in the treatment of cognitive dyslexia.
