Capuchin and rhesus monkeys show sunk cost effects in a psychomotor task
Scientific Reports, 2020 Human decision-making is often swayed by irrecoverable investments even though it should only be based on future—and not past—costs and benefits. Although this sunk cost effect is widely documented and can lead to devastating losses, the underlying ...

Variation in grouping patterns, mating systems and social structure: what socio-ecological models attempt to explain [PDF]
, 2013 Socio-ecological models aim to predict the variation in social systems based on a limited number of ecological parameters. Since the 1960s, the original model has taken two paths: one relating to grouping patterns and mating systems and one relating to ...

A comparison between affiliative and agonistic behaviours in wild and captive Sapajus libidinosus (Spix, 1823) (Mammalia, Primates, Cebidae) [PDF]
Papéis Avulsos de Zoologia, 2022 Organisms modulate the expression of their behaviours through environmental contexts. Several studies have suggested that the frequencies of social behaviours may differ between captive and free-living primates.

Are capuchin monkeys (Cebus apella) inequity averse? [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2006 It has been reported that capuchin monkeys reject a less preferred food (LPF) when they see a partner capuchin receive a more preferred food (PF) for performing the same task. This behaviour was taken as evidence of ‘inequity aversion’, but an alternative hypothesis is that capuchins reject the LPF because of the mere presence of the PF. We tested this
