It is often said that people with “poor” reading suffer from dyslexia, but the exact diagnosis depends on how we interpret the term. Some scholars categorize all people who read 30 months lower than the expected level as Dyslexic, but this broad definition includes difficulties reading that may be due to incomplete follow-up at school, in sensor defects or low IQ. Some other researchers identify dyslexia in a narrower sense, as serious problems reading in people who have normal IQs and no other non-cognitive disability that could be responsible for their difficulty.
The dyslexic students read much more slowly than the standard students • utter mistake many words, mainly names and words that are not used as often, and also receive less information than what I have just read. When the mental reading, the adaptation of the eye to the Dyslexic takes twice as long compared to non-Dyslexic people. Also the Dyslexics tend to return to what, what they have already read. Extra, have difficulties in spelling, making three times more errors than non-dyslexic students.
Some scholars believe that the source of these problems is primarily the failure in handling the relationship between the printed words and sounds they produce. Although you can fit two written or two spoken words, the Dyslexics have extreme difficulties to match the written words with spoken. The best explanation for the inability of the Dyslexic to handle the connection between written and spoken seems to be that it is too slow to regain verbal information from long-term memory. When looking for representations of phonemes, of syllables, of morphemes in Greek or of words require an inordinate amount of time to find. This slowness generates a congestion that clogs their memory, which in turn prevents them from to devote enough memory in the process of understanding. Scholars also believe that the problems of storing and retrieving the names of written words can lead to such errors, like to call "ball" instead of "lamp”, as well as in other reverse problems that once led scientists to suspect that Dyslexics have some kind of Visual disorder.
