Assessment of Perceptual, Decoding, and Lexical Skills and Their Relation to Reading Proficiency. Technical Report No. 1.
Frederiksen, John R.
This report summarizes studies of perceptual, decoding, and lexical stages of processing in reading. Using a letter identification task, it was found that subjects who were low in overall reading ability scan a visual image more slowly than do high ability readers and are slower in identifying letters when they do not occur in a familiar sequence. Using an oral reading task, it was found that low ability readers rely on holistic properties of words (presumably their visual characteristics) in recognizing common words, while high ability readers tend to use decoding skills in recognizing both common and uncommon words. Using a lexical decision task, it was found that decoding proceeds more slowly when the stimulus item is visually unfamiliar. While low ability readers were more susceptible to the effects of visual familiarity, they did not differ from high ability readers in times for lexical access and retrieval. (AA)
