Abstract

Exemplar-based accounts of spoken word recognition suggest that lexical access is influenced by perceptual congruency in social information between a talker-specific acoustic signal and the word being accessed. An eye-tracking experiment was designed to examine how immediately listeners consider such socially indexed word- talker associations, with a hypothesis that in the period before the auditory target was perceptually disambiguated from its cohort competitor, more eye fixations would be made to the visual target word when the target word was associated with the same age category as the given talker than when it was produced by an age-mismatched talker. However, an unexpected pattern was found: age-indexed target words that mismatched the age of the talkers received more fixations than age-matched targets, in a time span following phonetic disambiguation. Post-hoc hypotheses and suggestions for future research are provided discussing how listener expectations about the word are formed and strengthened by task-driven attention-shifting and probabilistically rich or poor fit between the word and age in long-term memory.
