Compare and contrast 2 theoretical accounts of developmental dyslexia Essay

Compare and contrast 2 theoretical accounts of developmental dyslexia - Essay ExampleThe distinguishing traits of the watch include reading and writing difficulties. It is surmised that it spawns from sensory dysfunctions, and these have been thoroughly backed up by verifiable research. However, the definitive cause of the condition is yet to be determined (Coleman, 2002). The disorder has frequently been hypothesized to be the aftermath of various sensory malfunctions. After years of research, it has been indicated that dyslexia also has visual and writing aspects, making it a tuition disability that debilitates optimized performance (Francks et al, 2002).This essay aims to comparison the two theories of dyslexia at the biological, cognitive and behavioral levels. However, before undertaking this comparison, it is important to lay down the different theories that explain this condition. These are the phonological, the magnocellular (auditory and visual) and the cerebellar theor ies (Ramus et al, 2002). I shall attempt to compare the phonological and cerebellar theories of dyslexia.Ramus et al (2002) undertook a multiple case study to evaluate the key theories explaining the neckcloth of dyslexia. The sample of the study was composed of 16 university students for the control group. They were given various tests to gauge dyslexic traits. The outcomes advise that majority of the respondents had a phonological shortfall and that this was enough cause for them to have dyslexia. That is, in contrast with the cerebellar theory that has auditory and visual deficits as requisites to dyslexia, the study points out that the presence of a phonological deficit alone defines the condition. The presence of auditory deficits only worsens the condition, but are not necessarily required for having dyslexia. These deficits core in literacy impairments. Moreover, the study did not reinforce that motor deficiencies are rooted on the cerebellum (Ramus et al, 2002).At the bio logical and cognitive levels, the phonological deficit theory
