Contexts of Anointing Behavior in a Group of Blond Capuchin Monkeys (Sapajus flavius) Inhabiting an Atlantic Forest Fragment. [PDF]
Am J PrimatolWild blond capuchin anoints with millipede species that secrete a chemical capable of repelling ectoparasites, suggesting a self‐medicative function. Social and solitary anointing bouts occurred at similar frequencies, but with greater engagement by adult males, indicating that anointing is a multifunctional behavior.

Taxonomic and sex differences in sagittal cresting among gracile and robust capuchin monkeys. [PDF]
J AnatIn this study, I show that there are interspecific differences in the frequency and pattern of sagittal cresting among six capuchin species. Four of the six species show sagittal cresting, with Cebus capucinus showing a different sagittal cresting pattern to that observed in three robust capuchin species. All four crested species show sexual dimorphism

A comparative assessment of hand preference in captive red howler monkeys, Alouatta seniculus and yellow-breasted capuchin monkeys, Sapajus xanthosternos. [PDF]
PLoS ONE, 2014 There are two major theories that attempt to explain hand preference in non-human primates-the 'task complexity' theory and the 'postural origins' theory.

Whole-body prepulse inhibition protocol to test sensorymotor gating mechanisms in monkeys. [PDF]
PLoS ONE, 2014 Prepulse inhibition (PPI) is the decrease of startle reflex amplitude when a slight stimulus is previously generated. This paradigm may provide valuable information about sensorimotor gating functionality.

Stone throwing as a sexual display in wild female bearded capuchin monkeys, Sapajus libidinosus. [PDF]
PLoS ONE, 2013 Capuchin monkeys (Sapajus spp.) in captive settings frequently manipulate and throw objects. In the wild, they may push or drop stones and sticks toward targets during inter- or intraspecific threat displays.

Endowment effect in capuchin monkeys [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2008 In humans, the capacity for economically rational choice is constrained by a variety of preference biases: humans evaluate gambles relative to arbitrary reference points; weigh losses heavier than equally sized gains; and demand a higher price for owned goods than for equally preferred goods that are not yet owned.

ON LOSS AVERSION IN CAPUCHIN MONKEYS [PDF]
Journal of the Experimental Analysis of Behavior, 2008 Chen, Lakshminarayanan, and Santos (2006) claim to show in three choice experiments that monkeys react rationally to price and wealth shocks, but, when faced with gambles, display hallmark, human‐like biases that include loss aversion. We present three experiments with monkeys and humans consistent with a reinterpretation of their data that attributes ...

Understanding Solidity: Investigating Knowledge of a Functional Object Property in Brown Capuchin Monkeys (Sapajus apella) and Common Squirrel Monkeys (Saimiri sciureus) [PDF]
Animal Behavior and Cognition, 2020 Humans form abstract representations about the physical properties of objects, with very young infants having ‘core knowledge’ about solidity and continuity.

Capuchin Monkeys Alternate Play and Reward in a Dual Computerized Task [PDF]
Animal Behavior and Cognition, 2015 Many animals cooperate with one another to achieve outcomes that they could not obtain on their own. One form of cooperation that has received much attention but little empirical support from experimental studies is reciprocity, leaving open the question
