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 ...
Dyslexia does not affect general intelligence, but is often co-diagnosed with ADHD. [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]
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 ...
Dyslexia is a heterogeneous, dimensional learning disorder that impairs accurate and fluent word reading and spelling. [66] [67] 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 ...
Dyslexia. Dyslexia is a disorder characterized by problems with the visual notation of speech, which in most languages of European origin are problems with alphabet writing systems which have a phonetic construction. [1] Examples of these issues can be problems speaking in full sentences, problems correctly articulating Rs and Ls as well as Ms ...
Outline of dyslexia. The following outline is provided as an overview of and topical guide to dyslexia: Dyslexia, previously known as word blindness, is a learning disability ('learning difficulty' in the UK) that affects either reading or writing. Different people are affected to different degrees. Problems may include difficulties in spelling ...
Research in dyslexia. Dyslexia is a reading disorder wherein an individual experiences trouble with reading. Individuals with dyslexia have normal levels of intelligence but can exhibit difficulties with spelling, reading fluency, pronunciation, "sounding out" words, writing out words, and reading comprehension.
Compared to reading-unimpaired children cluster no. 1 had worse phonological awareness; cluster no. 2 had higher attentional costs; cluster no. 3 performed worse in the phonological, auditory, and magnocellular tasks. These results indicate that dyslexia may result from distinct cognitive impairments.
