Eye tracking, visual cognition, early development, individual differences
My research uses eye-tracking methods to examine elementary visual behaviors in infants and young children, particularly in situations that mimic natural dyadic (e.g., infant-parent) and triadic (i.e., infant-parent-objects) interactions. Of the many questions that are central to these topics, my current work focuses on individual differences in infant visual behavior, the origins of these differences, and their functional significance.
