Chromosome studies of Cebus apella: The standard karyotype of Cebus apella paraguayanus, Fischer, 1829

American Journal of Primatology, 1986
AbstractChromosome studies were performed on 40 specimens identified as Cebus apella paraguayanus, Fischer, 1829, which had been wild‐caught in Santa Catalina (Republic of Paraguay). Elongated chromosome spreads obtained from lymphocyte cultures were sequentially stained with different techniques, and a constant pattern of 382 bands was identified in ...

Picture processing in tufted capuchin monkeys (Cebus apella)

Behavioural Processes, 2009
Although pictures are frequently used in place of real objects to investigate various aspects of cognition in different non-human species, there is little evidence that animals treat pictorial stimuli as representations of the real objects. In the present study, we carried out four experiments designed to assess picture processing in tufted capuchin ...

Metamemory in tufted capuchin monkeys (Cebus apella)

Animal Cognition, 2009
Whereas evidence for metacognition by nonhuman primates has been obtained in great apes and old world monkeys, it is weaker in new world monkeys. For instance, capuchin monkeys may fail to recognize their own knowledge of the location of invisible bait. In the present study, we tested whether tufted capuchin monkeys would flexibly change their behavior

Early lateral bias in tufted capuchins (Cebus apella)

Developmental Psychobiology, 1998
We investigated the development of lateral bias in infant tufted capuchins (Cebus apella) by recording head orientation during the first 2 postnatal weeks and hand preference during Weeks 23 to 24 and 47 to 48. We found that lateral bias for head orientation at 1 to 2 weeks was negatively related to hand preference at 23 to 24 weeks.

Multifocal Candidiasis in a Capuchin Monkey ( Cebus apella)

Journal of Medical Primatology, 1977
Candidiasis involving nasal, pharyngeal, and intestinal mucosal surfaces and a pharyngeal lymph node was demonstrated microscopically in a young adult female capuchin monkey (Cebus apella) experimentally infected with Schistosoma haematobium (Iran strain).

Posture and Reaching in Tufted Capuchins (Cebus apella)

Laterality, 1997
This research investigated the effects of posture on lateral bias for food reaching in tufted capuchin monkeys ( Cebus apella ) by comparing hand preferences for quadrupedal and bipedal reaching. Several findings of this investigation warrant discussion.

Cognitive Processes in Cebus Monkeys (Cebus apella) when Solving Problem-Box Tasks

Folia Primatologica, 1986
Although monkeys are capable of solving problem-box tasks, they were said to perform without ‘understanding the value of unlocking’ and to use ‘kinesthetic control’ only [Kohts, 1928]. However, the cognitive processes are much more complex – at least in Cebus monkeys: the problem-solving process was conducted according to the position of the catch in ...

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.
