The phonological deficit hypothesis is a prevalent cognitive-level explanation for the cause of reading difficulties and dyslexia. [1] It stems from evidence that individuals with dyslexia tend to do poorly on tests which measure their ability to decode nonsense words using conventional phonetic rules, and that there is a high correlation between difficulties in connecting the sounds of ...
During the twentieth century, dyslexia was primarily seen as a phonological deficit (specifically phonological awareness) that resulted in a reading deficit. [5] [6] [7] Dyslexia was seen as an issue with reading achievement specifically, caused by deficits in discrimination of written word sounds as opposed to a broader disorder of brain ...
The dual-route hypothesis to reading can help explain patterns of data connected to certain types of disordered reading, both developmental and acquired. [9] Routes impaired in surface and phonological dyslexia. Children with reading disorders rely primarily on the sub-lexical route while reading. [10]
In the 1970s, a hypothesis emerged that dyslexia stems from a deficit in phonological processing, or difficulty in recognizing that spoken words are formed by discrete phonemes, for example, that the word CAT comes from the sounds [k], [æ], and [t]. As a result, affected individuals have difficulty associating these sounds with the visual ...
[1] [2] There are at least three sub-types of dyslexia that have been recognized by researchers: orthographic, or surface dyslexia, phonological dyslexia and mixed dyslexia where individuals exhibit symptoms of both orthographic and phonological dyslexia. [3] Studies have shown that dyslexia is genetic and can be passed down through families.
Some shared symptoms of the speech or hearing deficits and dyslexia: [3] Confusion with before/after, right/left, and so on; Difficulty learning the alphabet; Difficulty with word retrieval or naming problems; Difficulty identifying or generating rhyming words, or counting syllables in words (phonological awareness)
This approach "incorporates targeted speech production practice into phonological awareness activities and uses letters and phonological cues to prompt speech production". [26] McNeill, Gillon, & Dodd studied 12 children ages 4–7 with DVD/CAS who were treated with this approach two times a week for two six-week blocks of time (separated by a ...
Phonological processing skills make up the ability to identify and manipulate sounds in speech. Rapid automatized naming compose the ability to translate visual information whether of letters, objects or pictures into a phonological code.
