The paper examines vocal signaling in marmoset dyads during cooperation, finding that social hierarchy and task role determine which vocal signals are used and when.

The paper identifies a neural mechanism in the dmPFC of marmosets that uses social gaze to accumulate evidence for cooperative decisions.

This study shows marmosets use flexible, cognitively driven cooperation strategies in dyads, adapting based on partner identity and social relationships.

The paper introduces MarmoAAP, a novel apparatus for studying cooperative behaviors in common marmosets, enabling high-throughput behavioral data collection and integration with video/audio for detailed analysis.
