An inversion effect modified by expertise in capuchin monkeys

Animal Cognition, 2011
The face inversion effect may be defined as the general impairment in recognition that occurs when faces are rotated 180°. This phenomenon seems particularly strong for faces as opposed to other objects and is often used as a marker of a specialized face-processing mechanism.

Resistance of capuchin monkeys to reinfection with Schistosoma haematobium

Transactions of the Royal Society of Tropical Medicine and Hygiene, 1988
Capuchin monkeys were resistant to reinfection with Schistosoma haematobium one year after exposure to 500 cercariae, but worms in these monkeys continued to produce normal numbers of eggs. Monkeys were apparently completely refractory to reinfection when challenged 2-5 years after an initial exposure of 1000 to 2000 cercariae.

Handedness and cortisol in tufted capuchin monkey infants

Developmental Psychobiology, 2000
In this research, we examined the relationship between handedness and levels of plasma cortisol in infant monkeys (Cebus apella). Specifically, we sought to test the hypothesis that stress functioning is related to hemispheric specialization and is manifested in a positive correlation between cortisol levels and the frequency of right- versus left-hand

Capuchin monkey research priorities and urgent issues

American Journal of Primatology, 2014
The “Capuchin research community roundtable: working together towards a comparative biology of Cebus and Sapajus” was held at the International Primatological Society Congress in Cancún, Mexico, August 2012. Goals of the roundtable were to strengthen interactions among the capuchin research community, and to prioritize and coordinate research and ...

Intrinsic organization of the suprachiasmatic nucleus in the capuchin monkey

Brain Research, 2014
The suprachiasmatic nucleus (SCN), which is the main circadian biological clock in mammals, is composed of multiple cells that function individually as independent oscillators to express the self-sustained mRNA and protein rhythms of the so-called clock genes.

Tool choice on the basis of rigidity in capuchin monkeys

Animal Cognition, 2011
Wild capuchin monkeys select stone tools to crack open nuts on the basis of their weight and friability, two non-visual functional properties. Here, we investigated whether they would select new stick-like tools on the basis of their rigidity. In Experiment 1, subjects faced an out-of-reach reward and a choice of three unfamiliar tools differing in ...

Three‐dimensional kinematics of capuchin monkey bipedalism

American Journal of Physical Anthropology, 2011
AbstractCapuchin monkeys are known to use bipedalism when transporting food items and tools. The bipedal gait of two capuchin monkeys in the laboratory was studied with three‐dimensional kinematics. Capuchins progress bipedally with a bent‐hip, bent‐knee gait. The knee collapses into flexion during stance and the hip drops in height.
