This study shows that food calls in marmosets predict sharing decisions, with acoustic features influencing whether food is transferred or not.

This study shows nonhuman primates use supra-regular recursive grammars in vocal sequences, challenging the idea that syntax is unique to humans.

This study shows marmosets adjust their vocalizations to match partners, indicating normative expectations in social communication.

This study shows marmoset phee calls encode external events like food context beyond emotional arousal and valence, even without an immediate stimulus.

The paper examines volubility and vocal coordination in common marmosets under different experimental conditions, finding call-type-specific patterns of vocal contagion and recruitment.

The paper introduces an automated wireless reward delivery system for marmosets to study social behavior while maintaining group housing and minimizing human intervention.

This study analyzes testosterone dimorphism across mammals, finding no clear link to paternal care or sexual size dimorphism, but highlighting sampling matrix effects on testosterone ratios.

This paper introduces MDCA-Pr, a method for analyzing animal signal combinations, showing it improves statistical rigor and enables accurate comparisons between cohorts.

This study shows that common marmosets adjust their vocal sequence structure, but not acoustic features, during pair formation, suggesting sequence-level vocal convergence driven by social bonds.

This study evaluates an acoustic camera for detecting and attributing vocalizations in marmosets, showing high detection rates and accuracy with limitations from spatial crowding and source level differences.

This study examines the development of play behavior in common marmoset infants, showing that social play increases with age and that adults remain important play partners despite the presence of twins.

The paper evaluates machine learning methods for caller identity classification in mammalian vocalizations, finding Mel-frequency cepstral coefficients and random forests provide consistent results across datasets.

This study compares memory performance of common marmosets in two tasks, finding they excel in a long-term spatial memory test but perform poorly in a classical delayed response task.

This study examines neurodevelopmental timing in marmosets, linking brain development to social and behavioral milestones, and suggests implications for human social cognition.

This study shows common marmosets use body posture signals to regulate social play by increasing play probability, duration, diversity, and likelihood of play fighting.

This study examines the relationship between brain size and short-term memory in primates, finding that overall brain size better predicts performance than specific brain regions or encephalization quotient.

The paper analyzes the acoustic structure and informational content of common marmoset phee sequences, finding that elements encode caller identity and sex with varying accuracy across positions.
