Abstract Recent reports on tool use in nonforaging contexts have led researchers to reconsider the proximate drivers of instrumental object manipulation. In this study, we explore physiological and behavioral correlates two stone‐directed seemingly playful actions, repetitive tapping rubbing stones onto genital inguinal area, respectively, that may been co‐opted into self‐directed tool‐assisted masturbation long‐tailed macaques (i.e., “Sex Toy” hypothesis). We predicted stone‐tapping would...
Abstract Although play–fighting is widespread among juvenile mammals, its adaptive significance remains unclear. It has been proposed that play beneficial for developing skills to improve success in adult contests (motor‐training hypothesis), but the links between and aggression are complex not well understood. In this theoretical study, we investigate coevolution using evolutionary computer simulations. We consider a simple life history with two sequential stages: phase which individuals...
The details of the evolutionary steps in transition from nonvisual guidance hand movements for feeding, as displayed by many non-primate species, to visual primates are sparse. Contemporary theory holds that a small-bodied stem primate evolved control reach guide obtain small insects and fruit items terminal branches trees. subsequent evolution finger shaping grasp anthropoids is uncertain. present study finds Balinese long-tailed macaques (Macaca fascicularis), video recorded while...
Object affordances play a major role in action expression: (a) providing opportunities to generate potential solutions instrumental problems and (b) shaping constraining the motor actions available an individual. The playful manipulation of objects can facilitate individual acquisition functional object-assisted through affordance learning. We tested "object affordance" hypothesis free-ranging long-tailed macaques. This holds that physical properties associated with stone size afford...
Abstract While tool use has been widely reported in non-human animals for food acquisition, the of tools drinking largely overlooked, with primates being a notable exception. We documented tool-assisted water scooping and several Balinese long-tailed macaques ( Macaca fascicularis ), living Ubud, Indonesia, over period four years. observed repeated using leaves, nuts, pits, stones. Our results indicate that this behaviour is associated manual can be performed playful context. This population...
Abstract We documented evidence of idiosyncratic but repeated twig-assisted genital stimulation by Balinese long-tailed macaques ( Macaca fascicularis ), living in Ubud, Indonesia. This population is known to customarily engage stone-tapping/-rubbing, a behaviour expressed males and females different age classes as part broader cultural repertoire stone-directed overall playful actions stone handling. However, using other objects has never been reported this species. observed extensive one...
