Contrary to the causal claims being made, my analysis suggests that information on the nature of dyslexia, a review of theories about dyslexia, an overview of approaches and programmes used by specialists who support dyslexic learners and a A multiple case study was conducted in order to assess three leading theories of developmental dyslexia: the phonological, the magnocellular (auditory and visual) and Theories about Developmental Dyslexia. In this handbook, the world’s leading researchers answer fundamental questions about dyslexia and dyscalculia Here, the evidence for and against several prominent sensory theories of dyslexia is closely scrutinized. What are these additional risks and how can they be conceptualised? All these new theories converge on the idea that DD is fundamentally caused by impaired signalling of the timing of the visual and auditory cues that are essential for reading The recent explosion of theories about DD is testament to how little we really know about the normal development of reading, let alone in developmental dyslexia. by. Department of Physiology, Anatomy & Genetics, Oxford University, Oxford OXPT, UK. Brain Sci.,(2), ¾ There are three main deficit theories on what causes the characteristics of dyslexia: o The phonological deficit theory explains difficulties dyslexic individuals show linking A multiple case study was conducted in order to assess three leading theories of developmental dyslexia: (i) the phonological theory, (ii) the magnocellular (auditory and visual) theory and (iii) the cerebellar theory The recent explosion of theories about DD is testament to how little we really know about the normal development of reading, let alone in developmental dyslexia. These new DD theories can be divided intobroad categories, psychological, signal processing, and neurological, but it is argued that only the latter can really provide useful Based on statistical models of how variance in reading skill is parceled across measures of visual processing, phonological processing, and ision-making, our results chal-lenge the notion that a unifying deficit characterizes dyslexia A multiple case study was conducted in order to assess three leading theories of developmental dyslexia: the phonological, the magnocellular (auditory and visual) and the cerebellar theories. Sixteen dyslexic andcontrol university students were administered a full battery of psychometric, phonological, auditory, visual and cerebellar tests Four major theories of developmental dyslexia are discussed: the phonological deficit theory, the double-deficit theory, the magnocellular theory, and the cerebellar All these new theories converge on the idea that DD is fundamentally caused by impaired signalling of the timing of the visual and auditory cues that are essential for reading According to the influential theory by Pennington (Citation), dyslexia is the outcome of multiple risks which accumulate towards a threshold for what is usually termed ‘diagnosis’. These new DD Competing theories of dyslexia posit that reading difficulties arise from impaired visual, auditory, phonological, or statistical learning mechanisms. Importantly, many theories The competing theories of the causes of dyslexia and the confusion caused by the presence of co morbid conditionsmore the norm than the exception within The Cambridge Handbook of Dyslexia and Dyscalculia.
