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

    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). This dataset cannot be published openly due to ethics restrictions. To discuss access to the data, please contact Eylem Altuntas ORCID 0000-0002-3239-6682.
