Stone tools differences across three capuchin monkey populations: food’s physical properties, ecology, and culture

Scientific Reports, 2022
Robust capuchin monkeys (Sapajus) are known for processing mechanically challenging foods, having morphological adaptations to do so. However, several populations go beyond body limitations by using stone tools to expand their food range.

Rates of agonism among female primates: a cross-taxon perspective [PDF]

, 2013
Agonism is common in group-living animals, shaping dominance relationships and ultimately impacting individual tness. Rates of agonism vary considerably among taxa, however, and explaining this variation has been central in ecological models of female ...

Monkeys Wait to Begin a Computer Task when Waiting Makes Their Responses More Effective [PDF]

Animal Behavior and Cognition, 2014
Rhesus monkeys (Macaca mulatta) and capuchin monkeys (Cebus apella) performed a computerized inhibitory control task modeled after an “escalating interest task” from a recent human study (Young, Webb, & Jacobs, 2011).

Economic man – or straw man? [PDF]

, 2005
The target article by Henrich et al. describes some economic experiments carried out in fifteen small-scale societies. The results are broadly supportive of an approach to understanding social norms that is commonplace among game theorists.

Wild Bearded Capuchin Monkeys Crack Nuts Dexterously [PDF]

Current Biology, 2015
Dexterous tool use has been crucial in the evolution of hominid percussive technology. According to Newell, "dexterity" is the ability of an organism to make goal-directed corrections in movements to optimize effort. Dexterous movements are smooth and effective and accomplish the same goal with less energy than less dexterous movements.

Proximate factors underpinning receiver responses to deceptive false alarm calls in wild tufted capuchin monkeys: is it counterdeception? [PDF]

, 2012
Previous research demonstrates that tufted capuchin monkeys use terrestrial predator alarm calls in a functionally deceptive manner to distract conspecifics when feeding on contestable resources, although the success of this tactic is limited because ...

Intuitive probabilistic inference in capuchin monkeys

Animal Cognition, 2016
The ability to reason about probabilities has ecological relevance for many species. Recent research has shown that both preverbal infants and non-human great apes can make predictions about single-item samples randomly drawn from populations by reasoning about proportions.

Eye preferences in capuchin monkeys (Sapajus apella) [PDF]

Primates, 2016
This study explored whether capuchin monkey eye preferences differ systematically in response to stimuli of positive and negative valence. The ‘valence hypothesis’ proposes that the right hemisphere is more dominant for negative emotional processing and the left hemisphere is more dominant for positive emotional processing. Visual information from each

Same/different concept learning by capuchin monkeys in matching-to-sample tasks.

PLoS ONE, 2011
The ability to understand similarities and analogies is a fundamental aspect of human advanced cognition. Although subject of considerable research in comparative cognition, the extent to which nonhuman species are capable of analogical reasoning is ...
