Difficulties with ReadingWhat mystifies many parents is where and why the reading process breaks down. Although, problems may occur in any area, decoding, comprehension, or retention, the root of most reading problems, in the view of many experts, is decoding.
Decoding DifficultiesDecoding is the process by which a word is broken into individual phonemes and recognized based on those phonemes. For instance, proficient decoders separate the sounds "buh," "aah," and "guh" in the word "bag." Someone who has difficulty decoding, and thus difficulty reading easily, may not hear and differentiate these phonemes. "Buh," "aah," and "guh" might be meaningless to them in relation to the word "bag" on the page.
Experts have no one explanation for this phenomenon. In some cases, it may reflect that some people simply require more time to separate sounds -- time that isn't there.
Signs of decoding difficulty:
Comprehension DifficultiesComprehension relies on mastery of decoding; children who struggle to decode find it difficult to understand and remember what has been read. Because their efforts to grasp individual words are so exhausting, they have no resources left for understanding.
Signs of comprehension difficulty:
Retention DifficultiesRetention requires both decoding and comprehending what is written. This task relies on high level cognitive skills, including memory and the ability to group and retrieve related ideas. As students progress through grade levels, they are expected to retain more and more of what they read. From third grade on, reading to learn is central to classroom work. By high school it is an essential task.
Signs of retention difficulty:
Problems with phonemes
Contrary to popular misconception, dyslexia is not characterized by letter or word reversal. In fact, dyslexia is a language-processing difficulty caused by the inability to break words into phonemes. Experts estimate that dyslexia, the most common reading difficulty, affects as many as 15 percent of all Americans.
Recent studies show a neurobiological basis for dyslexia, suggesting the potential for early diagnosis and new forms of treatment. This research describes a biological cause of the disorder; evidence that dyslexia does not reflect lack of intelligence, or attention, or effort. In addition, this reasearch may reveal better ways of diagnosing and treating reading problems.
In one experiment, for example, scientists presented a group of dyslexics and people who read easily with an increasingly difficult series of reading tasks. The researchers used brain-imaging equipment to monitor the level of activity (as indicated by the flow of oxygenated blood) in each subject's brain during the tasks. In proficient readers, as the tasks grew more difficult, new regions of the brain were recruited. This recruitment traveled generally from the rear of the brain toward the front. In contast, activity in poor readers occurred less in rear portions of the brain and much more in front portions of the brain than in proficient readers.
This pattern is now believed to be the "neural signature" of dyslexia. As more is learned about the meaning of this "signature," more strategies for improving reading will be developed.
