Sexual behavior in brown capuchins (Cebus apella)

International Journal of Primatology, 1994
We observed sexual behavior patterns in two captive groups of Cebus apella.We obtained data on intersexual solicitations and intersexual competition. The length of proceptivity cycles by females averaged 18.8 ± 1.2 days; this corresponds with published reports of physiological measures of ovulatory cycles.

Coping with Acute Crowding by Cebus apella

International Journal of Primatology, 2006
Traditionally, scientists believed that crowded housing conditions increased aggression in animals. Recent research on captive primates fails to support a linear relationship between population density and aggressive behavior. Our study is the first to investigate the effects of acute crowding on a New World primate.

Face recognition in capuchin monkeys (Cebus apella).

Journal of Comparative Psychology, 2009
Primates live in complex social groups that necessitate recognition of the individuals with whom they interact. In humans, faces provide a visual means by which to gain information such as identity, allowing us to distinguish between both familiar and unfamiliar individuals. The current study used a computerized oddity task to investigate whether a New

Reunion displays in captive male brown capuchins (Cebus apella)

Primates, 2004
Separation and subsequent reintroduction of brown capuchins (Cebus apella) can lead to reunion displays during which individuals will embrace and emit high-pitched, loud vocalizations. These displays were investigated in three male capuchins: two adults and one juvenile.

Capuchin (Cebus [Sapajus] Apella) Change Detection

2018
Change blindness is a phenomenon in which individuals fail to detect seemingly obvious changes in their visual fields. Like humans, several animal species have also recently been shown to exhibit change blindness; however, no species of New World monkey has been tested to date.

Food variety-seeking in tufted capuchin monkeys (Cebus apella)

Physiology & Behavior, 2008
Variety-seeking is a central issue to consumer behaviour research and a phenomenon of crucial relevance, both for human and animal nutrition. Variety-seeking increases the probability of nutrient adequacy in omnivores, and in humans it may also contribute to obesity epidemic by diversifying food selection and leading to excessive food intake.
