Hyperlexia: A Case of Reading without Meaning.
Glosser, Guila; And Others
Single word oral reading was systematically examined in a 6-year-old hyperlexic boy with mental retardation, attention deficit disorder, and hyperactivity. Reading performances were compared to those of normally developing readers and to those of patients with adult-onset alexias to test three hypotheses regarding the mechanisms of reading in hyperlexia. Part-of-speech, imageability, visual configuration, or orthographic regularity had no effect on oral reading. Skills for phonological decoding of all types of real words and for pseudowords that match frequent English orthographic patterns were at reading grade level, but reading was poor for pronounceable pseudowords that have no real word analogies in English. Written word comprehension depended completely on the ability to decipher words phonologically. There did not appear to be any independent contribution of semantics to reading, and reading proceeded primarily or exclusively through a direct phonological lexical route. In all respects the reading pattern in this case matches that of adult patients with generalized dementia of the Alzheimer's type who read without meaning. (Author)
