Developmental dyslexia is a lifelong condition that manifests itself as a reading and spelling impairment. This thesis explored the quality of lexical representation in the neurotypical and dyslexic populations, using a suite of individual difference measures and the masked priming paradigm. Chapters 2 and 3 revealed that in the neurotypical population, the priming effect in word recognition was driven by a component related to phonological precision, while a factor linked to orthographic precision contributed to the priming effects of word and pseudoword production. Chapter 4, demonstrated in the dyslexic population, the priming effects in word and pseudoword rejection was driven by a component linked to lexical precision, whereas no individual factor drove the priming effects for word or pseudoword production. Chapter 5 showed that that 34% of people with dyslexia had stuttered during childhood, with the prevalence rate being moderated by the severity of dyslexia. In addition, people with dyslexia did not differ from people who stutter in any phonological processing measures. These findings indicate that people with dyslexia have a phonological, together with orthographic precision, impairment.
