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 ...
Surface dyslexia was imitated by damaging the orthographic lexicon so that the program made more errors on irregular words than on regular or non-words, just as is observed in surface dyslexia. [6] Phonological dyslexia was similarly modeled by selectively damaging the non-lexical route thereby causing the program to mispronounce non words.
The double-deficit theory of dyslexia [1] [2] ... Phonological processing skills make up the ability to identify and manipulate sounds in speech.
Dyslexia is a heterogeneous, dimensional learning disorder that impairs accurate and fluent word reading and spelling. [65] [66] Typical—but not universal—features include difficulties with phonological awareness; inefficient and often inaccurate processing of sounds in oral language (phonological processing); and verbal working memory ...
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 ...
Phonological processing tasks predict reading accuracy and comprehension. [23] Cestnick and Jerger (2000) [25] and Cestnick (2001) [26] further demonstrated distinct processing differences between phonological and surface dyslexics. Manis et al. 1996, concluded that there were probably more than two subtypes of dyslexia, which would be related ...
Dyslexia is a learning difficulty that primarily affects the skills involved in accurate and fluent word reading and spelling. Characteristic features of dyslexia are difficulties in phonological awareness, verbal memory and verbal processing speed. Dyslexia occurs across the range of intellectual abilities.
