Two-year-olds’ sensitivity to subphonemic mismatch during online spoken word recognition

摘要: Sensitivity to noncontrastive subphonemic detail plays an important role in adult speech processing, but little is known about children’s use of this information during online word recognition. In two eye-tracking experiments, we investigate 2-year-olds’ sensitivity a specific type detail: coarticulatory mismatch. Experiment 1, toddlers viewed images familiar objects (e.g., boat and book) while hearing labels containing appropriate or inappropriate coarticulation. Inappropriate coarticulation was created by cross-splicing the coda target onto onset another that shared same nucleus create boat, final consonant cross-spliced initial CV bone). We tested 24-month-olds 29-month-olds paradigm. Both age groups behaved similarly, readily detecting (i.e., showing better recognition identity-spliced than items). 2, asked how mismatch compared their phonemic Twenty-nine-month-olds were presented with targets contained either spliced bait) Here, (coarticulatory) not nearly as disruptive Taken together, our findings support view 2-year-olds, like adults, optimize
