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 ...
Phonological dyslexia is a reading disability that is a form of alexia (acquired dyslexia), [1] resulting from brain injury, stroke, or progressive illness and that affects previously acquired reading abilities. The major distinguishing symptom of acquired phonological dyslexia is that a selective impairment of the ability to read pronounceable ...
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)
[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.
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 ...
Acquired phonological dyslexia is a type of dyslexia that results in an inability to read nonwords aloud and to identify the sounds of single letters. However, patients with this disability can holistically read and correctly pronounce words, regardless of length, meaning, or how common they are, as long as they are stored in memory.
The term "protracted phonological development" is sometimes preferred when describing children's speech, to emphasize the continuing development while acknowledging the delay. A study in the United States estimated that amongst 6 year olds, 5.3% of African American children and 3.8% of White children have a speech sound disorder. [1]
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 ...
