“…Capuchin natural history might well underlie their strong responsiveness to the provision of simple, inanimate toys and foraging boxes and the extent of their abnormal behavior without such stimuli. The extreme manipulative proclivities and abilities of capuchins observed in the wild [Janson & Boinski, 1992;Fragaszy & Boinski, 1995] are also apparent in captivity [Fragaszy & Adams-Curtis, 1991;Byrne & Suomi, 1996]. Perhaps capuchins are more likely to exploit and more reliant upon the presence of relatively low-stimulus manipulative opportunities compared to many other primate taxa.…”

“…Capuchins exhibit a great variety of behaviours to explore and act on the environment especially while foraging (Fragaszy et al 2004;Perry and Manson 2008;Terborgh 1983). Both wild and captive capuchins spontaneously perform objectobject and object-surface combinations (Byrne and Suomi 1996;Fragaszy and Adams-Curtis 1991;Fragaszy and Boinski 1995;Panger 1998;Visalberghi 1988), tool use (Ottoni and Mannu 2001;Visalberghi and Fragaszy 2013), and gather information about tool affordances in the absence of extrinsic rewards (Manrique et al 2011). …”

Exploration and learning in capuchin monkeys (Sapajus spp.): the role of action–outcome contingencies

Animals have a strong propensity to explore the environment. Spontaneous exploration has a great biological signifcance since it allows animals to discover and learn the relation between specifc behaviours and their consequences. The role of the contingency between action and outcome for learning has been mainly investigated in instrumental learning settings and much less in free exploration contexts. We tested 16 capuchin monkeys (Sapajus spp.) with a mechatronic platform that allowed complex modules to be manipulated and to produce different outcomes. Experimental subjects could manipulate the modules and discover the contingencies between their own specifc actions and the outcomes produced (i.e., the opening and lighting of a box). By contrast, Control subjects could operate on the modules but the outcomes experienced were those performed by their paired Experimental subjects ("yoked-control" paradigm). In the Exploration Phase, in which no food reward was present, Experimental subjects spent more time on the board and manipulated the modules more than Yoked subjects. Experimental subjects outperformed Yoked subjects in the following Test phase, where success required recalling the effective action so to open the box, now baited with food. These fndings demonstrate that the opportunity to experience action-outcome contingencies in the absence of extrinsic rewards promotes capuchins' exploration and facilitates learning processes. Thus, this intrinsically motivated learning represents a powerful mechanism allowing the acquisition of skills and cognitive competence that the individual can later exploit for adaptive purposes.

“…Infants and juveniles who are closer to some group members, and are better tolerated by them, may have more opportunities to observe new behaviors and learn new skills. Proximity to adult males may, in particular, lead to increased opportunities, as they often have preferential access to food or novel objects [Byrne & Suomi, 1996;DiBitetti & Janson, 2001;Janson, 1984;Visalberghi, 1988]. Facial inspection to adult males in this study became more frequent (at least for male infants) and more consistent late in the first year; this is a time when weaning may begin for some infants, and their foraging demands may increase.…”

The development and individual stability of three intimate social behaviors (Lipsmacking, Carrying Attempts, and Facial Inspection) were examined for 43 group-housed Cebus apella infants from birth to 2 years of age. Occurrence of these behaviors was scored from 10-min videotape samples recorded three times a week over that time. Frequency of Lipsmacking and Carrying Attempts by adult males, adult females, and juveniles were all highest in early months and decreased to low levels by the end of the first year. Facial Inspection of partners by infants, in contrast, first began at 3-4 months and increased over time, at least to adult males and juveniles. Correlational analyses indicated stable individual differences in these interactions with infants and outlined a relationship between these intimate behaviors and more general social patterns reported previously for these animals. Results suggest that adult males may play a special role in affording juveniles opportunities for social learning of foraging and manipulative skills.
