Speech disfluencies can guide the ways in which listeners interpret spoken language. Here, we examined whether three-year-olds, five-year-olds, and adults use filled pauses to anticipate that a speaker is likely to refer to a novel object. Across three experiments, participants were presented with pairs of novel and familiar objects and heard a…

Previous research suggests that English monolingual children and adults can use speech disfluencies (e.g., "uh") to predict that a speaker will name a novel object. To understand the origins of this ability, we tested 48 32-month-old children (monolingual English, monolingual French, bilingual English-French; Study 1) and 16 adults…

Examines infants' sensitivity to word units in fluent speech by inserting one-second pauses either at boundaries between successive words or between syllables within words. Results indicate that, by 11 months, infants are sensitive to word boundaries, and that this sensitivity depends on more than prosodic information or prior knowledge. (65…
