Phonological deficit

Channel 4 Dispatches programme entitled ‘The Dyslexia Myth’¹ was aired in September 2005. The purpose of the documentary was to inform society of the proposed misconceptions and myths of the condition which affects 1 in 5 people. The programme details how the common understanding of the learning impairment is not only false, but how this particular diagnosis makes it harder for children with reading difficulties to receive help. The director of the documentary clearly wants to get across the message

study supports the phonological deficit hypothesis as it suggests that dyslexic children show early deficiencies in speech production. Although the role of heritability is important to consider, due to the real world implications it has of helping to identify ‘at-risk’ children who are more likely to develop dyslexia, it cannot explain why there is only a 50 per cent rate of heritability for dyslexia. There has also been very little research into the heritability of either deficits in visual processing

Dyslexia; theory of a Phonological deficit Dyslexia or DRD is described as the difficulty with learning to read fluently despite regular intelligence. This includes struggles with letter awareness, letter decoding, processing speed, short-term memory, language skills/verbal understanding, and rapid naming (Silverman, L. (2000). Dyslexia is a very common learning difficulty and a highly recognized reading disorder. According to Castles, A. 2014; there are two types of dyslexia: “Acquired dyslexia

be achieved by a collective approach. This kind of approach would encompass ideas placed forth by both the cognitive and neurological theoretical ideas which currently existed in the current research of the etiology of dyslexia. The phonological deficit hypothesis of dyslexia is one of the most long standing explanations existing in psychological research. The theory was coined by a man known as the father of dyslexia, Pringle-Morgan in 1896. Morgan viewed reading as a process that critically

It can also have an impact on cognitive processing such as memory, speed of processing, time management, co-ordination and automaticity. There may be visual and/or phonological difficulties and there are usually some discrepancies in education performances”.(Reid, G) There are three types of definitions of Dyslexia. One being a Descriptive definition, a Discrepancy based definition and the third a Criteria based definition

review of research on the fundamental cause(s) of developmental dyslexia. The secondary purpose is to present the evidence that reveals differences between early reading difficulties caused mainly by cognitive/biological deficits and those caused primarily by instructional deficits. The authors first propose a model that captures all the relevant knowledge and cognitive skills required for individuals in learning to read (figure 1). This model certainly indicates that reading is mainly a linguistic

and found that language and letter knowledge assessed at Phase 1 predicted phonological awareness and grapheme-phoneme skill at Phase 2 (6 years), which then predicted word-level reading skills at Phase 3 (8 years). Additionally, it is important to notice that Snowling et al. (2003) found that so-called unaffected children from high-risk family performed significantly better than impaired children in the tests of phonological skills, while they performed significantly poor in digit span and rhyme

There is a widespread consensus that the developmental deficits in phonological skills characterize dyslexia. Phonological skills as the broad umbrella term include phonological awareness (PA), which refers to the ability to reflect upon and manipulate the sound structure of spoken words (Goswami & Bryant, 1990; Mattingly, 1972); and phonological processing, which involves access to phonological codes without necessarily explicit awareness of the sound structure of spoken words (Melby-Lervåg, Lyster

processes, it becomes necessary to recover lexical elements phonological or indirectly, and by visual orthographic means, generating recall of previously acquired knowledge, such as graphemes, phonemes, or words, and store them through memory. Therefore, memory is required for active
