Abstract

Experiments are reviewed that use the letter-detection task, in which subjects read text and circle target letters. Evidence is provided that the letter-detection task reveals the processing units used in reading text and is influenced as well by visual, phonetic, and a combination of semantic and syntactic factors. Specifically, it is shown that circling a target letter in a word depends on the familiarity of the word’s visual configuration, the location of the word in the reader’s visual field, the phonetic representation of the letter in the word, and a combination of the word’s meaning and its grammatical function.
