Literacy ability and phonological processing skills amongst dyslexic and non-dyslexic speakers of Arabic

This paper investigates the relationship between phonological processing and reading ability amongst grade 4 and grade 5 Arabic speaking children in Egypt. In addition to measuring reading level, the study assessed the children's ability to identify rhymes, delete individual phonemes from words, retain and manipulate sequences of digit names and rapidly access verbal labels. Further literacy and literacy-related tasks required children to decode novel letter strings, to distinguish similar words, to identify words within letter chains and to correctly spell dictated text. A non-verbal ability measure was also included to allow comparisons to be made between a group of poor readers with good non-verbal skills (dyslexics) with a control group of chronological-age-matched normal readers with equivalent average scores on the non-verbal task. Results indicated relationships between literacy ability, decoding and phonological processing within this cohort, as well as identifying differences between dyslexic and control groups that suggest Arabic dyslexics show signs of poor phonological skills. The study supports the view that Arabic dyslexic children have impairments in the phonological processing domain.
