Dr. Paola Escudero
MARCS Auditory Laboratories, University of Western Sydney, Australia

Within the category formation project at the CSCA, we investigate how infants use auditory/linguistic and visual information to classify the world around them. In this talk, I will present research on categorization in the linguistic and visual domains separately, on the relative importance of visual versus linguistic information, and their integration in sound perception and word learning.

Infants and adults categorize the sounds of their language through the sounds’ specific auditory properties and their frequency distributions. I will show the intricate ways in which infants and adults integrate auditory dimensions to categorize native and non-native sounds, as well as how they are able to exploit frequency distributions in sound categorization. In the visual domain, I will show adult and infant sensitivity to distributional patterns through short exposure to sequences of objects. Data come from behavioural, eye-tracking and EEG studies.

Word learning studies with children younger than two years of age show that the integration of words and their picture meanings is most difficult when the words only differ in one sound. I will present our current research that shows differences in categorization learning depending on whether infants are exposed to stimuli containing a single dimension or both linguistic and visual information combined.
