Social interactions in nonhuman primates involve complex communication, outcome evaluation, and behavioral adjustments. Social gaze is a vital mechanism for gathering information during such interactions. We investigated the role of social gaze in cooperative behavior among common marmosets (Callithrix jacchus) using a cooperative lever-pulling task in a naturalistic setting. Marmoset pairs were placed in separate transparent compartments with access to levers and juice tubes. Successful juice delivery required simultaneous lever-pulling, necessitating coordination. We recorded their behavior
