A LISTENERS INVESTIGATION OF PRINTED WORD-PROCESSING

The present study examines the time course of lexical access in written-word recognition by comparing words with early and late uniqueness points (UPs). Three experiments, which used a normal (simultaneous) presentation of the letters under 3 different tasks (gender classification, naming, and semantic classification) provided no evidence for sequential processing. Rather, a small advantage in favor of words with late UP was found, which may be interpreted in terms of the lower n-gram frequencies of early-UP words. Experiment 4 supported this interpretation and discussed an alternative interpretation in terms of parafoveal preview of the initial letters. A last experiment, which used an incremental presentation of the word letters, gave rise to a UP effect comparable in size to that obtained in an auditory study, suggesting that a temporal distribution of the signal is a sufficient condition for directional processing.
