| Summary: | This literature review looks at dyslexia from a behavioural, neurological, and genetic perspective to assess the phonological theory of dyslexia. The theory was critically examined against other theories, of which most were found to be weakly supported. Overall findings across different orthographies suggest more similarities than differences in terms of behaviour manifestation and neurological imaging. More specifically, common dyslexic deficits include phonological processing, rapid naming, verbal short-term memory, along with neurological under activation in the left temporoparietal, left occipitotemporal, and left inferior frontal brain regions. High heritability estimates among family members and monozygotic twins from genetic studies suggest significant genetic influence on reading ability. Overall findings both support and challenge the phonological theory, highlighting the importance of future research along all perspectives. |
