This document summarizes a study that aims to investigate whether infants can use previous observations of collaborative behavior to predict future cooperation. In the study, infants will be familiarized with video clips showing actors cooperating or not cooperating to complete tasks. They will then observe a new actor and task to see if infants expect cooperation based on the previous actors' behaviors. The study also aims to explore what cues, such as eye gaze or body language, infants pay attention to during cooperative activities. The predictions are that infants will expect previous good collaborators to collaborate well with new partners, and poor collaborators to collaborate poorly, and that accidental behaviors may not influence expectations.
