Abstract

The effects of lexical and acoustic information on phoneme restoration were examined over three experiments. Experiment 1 compared the lexical effects in between the word and the fragment condition in a new task. Experiment 2 examined the roles of acoustic segments preceding and following the target phoneme. Experiment 3 explored the phoneme restorations in a divided attention condition. Both the word and the fragment condition produced phoneme restorations and the vowel segment was very important in restorations. The word condition yielded increased sensitivity in the divided attention condition. Three experiments converge to the conclusion that lexical information does not significantly contribute to phoneme restoration. Our results were discussed in view of current models of language processing.
