Amodal Phonological Abstraction in Infants, Vowel Hyperarticulation in Their Mothers’ Infant-Directed Speech, and Their Relationships to Later Vocabulary Size

This project investigates amodal abstraction in 4- to 6-month-old Australian English-learning infants, specifically their ability to distinguish between labial and coronal places of articulation in consonants. During the training phase, infants are exposed to labial non-words paired with one animal image and coronal multi-syllabic non-words paired with another. At test, they watch a silent video of a talker producing coronal and labial words, with these words paired either with the familiarised image or a novel one. The dataset includes:
• Excel spreadsheets containing trial-by-trial behavioural data, participant details, and coding of infants’ looking times.
• Video recordings used for manual coding of looking behaviour (i.e., whether the infant is looking at the screen or looking away).
