Effective tool choice by chimpanzees (Pan troglodytes): Learning and flexibility
Chimpanzees are proficient tool users and have been shown to use properties of weight and length to select effective tools. Researchers have, however, neglected to investigate whether chimpanzees utilize other tool properties. This study investigated whether chimpanzees use other properties to choose effective tools, how feedback influences their ability to select effective tools, and whether o...
متن کاملDevelopment of stone tool use by wild chimpanzees (Pan troglodytes).
At the age of 3.5 years, wild chimpanzees at Bossou, Guinea, begin to use hammer and anvil stones to crack oil-palm nuts to get the kernels. To clarify the developmental processes, the authors did a field experiment in which stones and oil-palm nuts were provided. Infant chimpanzees' stone-nut manipulation was observed and video recorded. Data were collected from 3 infants younger than 4 years ...
متن کاملScale-model comprehension by chimpanzees (Pan troglodytes).
The ability of chimpanzees (Pan troglodytes) to recognize the correspondence between a scale model and its real-world referent was examined. In Experiments 1 and 2, an adult female and a young adult male watched as an experimenter hid a miniature model food in 1 of 4 sites in a scale model. Then, the chimpanzees were given the opportunity to find the real food item that had been hidden in the a...
متن کاملReferential communication by chimpanzees (Pan troglodytes).
Two experiments were conducted to assess the referential function of chimpanzee (Pan troglodytes) gestures to obtain food. The chimpanzees received 1 trial per condition. In Experiment 1 (N = 101), in full view of the chimpanzee, a banana was placed on top of 1 of 2 inverted buckets or was hidden underneath 1 of the buckets. In Experiment 2 (N = 35), 4 conditions were presented in constant orde...
متن کاملImitation in neonatal chimpanzees (Pan troglodytes).
This paper provides evidence for imitative abilities in neonatal chimpanzees (Pan troglodytes), our closest relatives. Two chimpanzees were reared from birth by their biological mothers. At less than 7 days of age the chimpanzees could discriminate between, and imitate, human facial gestures (tongue protrusion and mouth opening). By the time they were 2 months old, however, the chimpanzees no l...
