By the end of their first year, infants are able to interpret many different types complex dynamic visual events, such as caused-motion, chasing, and goal-directed action. Infants this age also in early stages vocabulary development, producing words at around 12 months. The present work examined whether there meaningful individual differences infants’ ability represent causal events scenes these influence development. As part longitudinal Language 0-5 Project, 78 10-month-old were tested on three motion involving (a) (b) chasing behaviour, (c) movement. Planned analyses found that showed evidence understanding two event types, but not third. Looking behaviour each task was meaningfully related nor any correlations between tasks. results additional exploratory simulations suggested may be predictive looking times tasks reliably capturing knowledge. This raises questions about how convert experimental group designs measures, infant time behaviour.
