With alphabetic writing systems, phonological awareness plays a central role in reading acquisition; while phonological awareness in Chinese is much less important. Rather, reading in Chinese is strongly related to a child's writing skills, which depend on orthographic awareness and on motor memory.
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.
Phonological awareness is one component of a larger phonological processing system used for speaking and listening. [8] [9] [10] Phonological awareness is different from other phonological abilities in that it is a metalinguistic skill, requiring conscious awareness and reflection on the structure of language.
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 British Dyslexia Association defines dyslexia as "a learning difficulty that primarily affects the skills involved in accurate and fluent word reading and spelling" and is characterized by "difficulties in phonological awareness, verbal memory and verbal processing speed". [73] Phonological awareness enables one to identify, discriminate ...
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.
Depth of processing falls on a shallow to deep continuum. [citation needed] Shallow processing (e.g., processing based on phonemic and orthographic components) leads to a fragile memory trace that is susceptible to rapid decay. Conversely, deep processing (e.g., semantic processing) results in a more durable memory trace. [1]
Phonological awareness is an essential skill for reading, writing, listening and talking. Synthetic phonics involves the development of phonemic awareness from the outset. As part of the decoding process, the reader learns up to 44 phonemes (the smallest units of sound) and their related graphemes (the written symbols for the phoneme).
