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 ...
The rapid auditory processing theory is an alternative to the phonological deficit theory, which specifies that the primary deficit lies in the perception of short or rapidly varying sounds. Support for this theory arises from evidence that people with dyslexia show poor performance on a number of auditory tasks, including frequency ...
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 ...
The causes of dyslexia are not agreed upon, although the consensus of neuroscientists believe dyslexia is a phonological processing disorder and that dyslexics have reading difficulties because they are unable to see or hear a word, break it down to discrete sounds, and then associate each sound with letters that make up the word.
The dual-route system could explain the different rates of dyslexia occurrence between different languages (e.g., the consistency of phonological rules in the Spanish language could account for the fact that Spanish-speaking children show a higher level of performance in non-word reading, when compared to English-speakers).
Chinese children dyslexia often have both a visuospatial and phonological disorder which are independent of one another. This implies that unlike alphabetic orthographies where only a phonological or visuospatial disorder alone can cause dyslexia, Chinese children must suffer from both disorders for dyslexia to manifest.
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.
Although the term "dyspraxia" suggests a pure output disorder, [16] many – perhaps all – of these children have difficulty in doing tasks that involve mentally manipulating speech sounds, such as phonological awareness tasks. Children with DVD also typically have major literacy problems, and receptive language levels may be poor on tests of ...
