The defining feature of dyslexia—poor reading—is a behaviour that depends upon a range of cognitive abilities. A key challenge is to understand dyslexia’s cognitive or ‘proximal’ causes. Furthermore, a causal theory at the cognitive level of explanation provides the rationale for the design of interventions that can moderate dyslexia’s impact. ‘What are the cognitive causes of dyslexia?’ considers a number of different cognitive theories concerning the causes of dyslexia including the Verbal Deficit Hypothesis and the Phonological Deficit Hypothesis as well as theories proposing deficits in auditory, speech, or visual processing in dyslexia.
