Abstract	Four visual-world experiments, in which listeners heard spoken words and saw printed words, compared an optimal-perception account with the theory of phonological underspecification. This theory argues that default phonological features are not specified in the mental lexicon, leading to asymmetric lexical matching: Mismatching input ("pin") activates lexical entries with underspecified coronal stops ("tin"), but lexical entries with specified labial stops ("pin") are not activated by mismatching input ("tin"). The eye-tracking data failed to show such a pattern. Although words that were phonologically similar to the spoken target attracted more looks than did unrelated distractors, this effect was symmetric in Experiment 1 with minimal pairs ("tin-pin") and in Experiments 2 and 3 with words with an onset overlap ("peacock-teacake"). Experiment 4 revealed that /t/-initial words were looked at more frequently if the spoken input mismatched only in terms of place than if it mismatched in place and voice, contrary to the assumption that /t/ is unspecified for place and voice. These results show that speech perception uses signal-driven information to the fullest, as was predicted by an optimal perception account. (Contains 5 figures, 3 tables, and 3 footnotes.)
