Prosocial behaviour emerges independent of reciprocity in cottontop tamarins.
The cooperative breeding hypothesis posits that cooperatively breeding species are motivated to act prosocially, that is, to behave in ways that provide benefits to others, and that cooperative breeding has played a central role in the evolution of human prosociality. However, investigations of prosocial behaviour in cooperative breeders have produced varying results and the mechanisms contribu...
متن کاملTemporal cues in the antiphonal long-calling behaviour of cottontop tamarins
In primates, long-range communication is often mediated by the use of ‘long’ (or ‘loud’) calls. Beyond the acoustic classification of these calls and descriptions of the behavioural context in which they are produced, few experimental studies have examined how species-typical information is encoded in the structure of these signals. We present the results of eight experimental conditions design...
متن کاملPattern recognition mediates flexible timing of vocalizations in nonhuman primates: experiments with cottontop tamarins
To maximize transmission in noisy environments, vocalizing animals have evolved capacities to avoid the masking effects of biotic and abiotic sound sources, such as changing the structure and timing of acoustic signals. Here we explore this problem from a new angle, asking whether animals can extract predictive acoustic cues from an intermittently noisy environment and use this information to g...
متن کاملThe Effects of Unequal Reward Distributions on Cooperative Problem Solving by Cottontop Tamarins (Saguinus oedipus).
Cooperation among non-human animals has been the topic of much theoretical and empirical research, but few studies have examined systematically the effects of various reward payoffs on cooperative behaviour. Here, we presented heterosexual pairs of cooperatively breeding cottontop tamarins with a cooperative problem solving task. In a series of four experiments, we examined how the tamarins' co...
متن کاملProblem solving, inhibition and domain-specific experience: experiments on cottontop tamarins, Saguinus oedipus
We present the results of experiments on cottontop tamarins designed to explore the relationship between problem solving, inhibitory control and domain-specific experience. The colony was divided into two groups: tool-experienced (TE) and tool-inexperienced (TI). The TE group had previously participated in a series of tool-use experiments and revealed that, when selecting a tool, they used feat...
