Mental map in wild chimpanzees: An analysis of hammer transports for nut cracking

  title={Mental map in wild chimpanzees: An analysis of hammer transports for nut cracking},
  author={Christophe Boesch and Hedwige Boesch},
The mental map of wild chimpanzees is analyzed in the context of their transports of clubs and stones used for cracking two species of nuts of different hardness,Coula edulis andPanda oleosa, in the Tai National Park (Ivory Coast). For the harderPanda nuts, they transport the harder hammers, i.e., almost exclusively stones, hammers of greater weight, and the transports are longer than forCoula nuts. The analysis made for the transports forPanda nuts shows that they seem to remember the location… Expand

When to choose which tool: multidimensional and conditional selection of nut-cracking hammers in wild chimpanzees
This study investigated the selection of hammers used for cracking Coula nuts by wild chimpanzees in the Tai National Park, Cote d'Ivoire, taking account of the availability of potential tools at the site and time of tool selection, and found that chimpanzees took account of several variables at the same time when selecting nut-cracking tools.

New data on the use of stone tools by chimpanzees in Guinea and Liberia
Two types of use of “hammers” for cracking nuts by wild-living chimpanzees have been distinguished: (1) Relatively small stones are used by the chimpanzee community at Bossou in Guinea to crack theExpand
Distribution of potential suitable hammers and transport of hammer tools and nuts by wild capuchin monkeys
Findings show that wild capuchin monkeys selectively transport stones of appropriate size and hardness to use as hammers, thus exhibiting, like chimpanzees and humans, planning in tool-use activities. Expand
Tool-use for catching ants by chimpanzees at Bossou and Monts Nimba, West Africa
The use of tools by wild chimpanzees to catch ants was studied at Bossou and Monts Nimba, south-eastern Guinée. Insect-eating by chimpanzees at Bossou appears to be opportunistic and ant-catching wasExpand
Transport of Functionally Appropriate Tools by Capuchin Monkeys (Cebus apella)
Capuchin monkeys’ propensity for transporting tools is confirmed, their capacity to select the functionally appropriate tool for two different tool‐use tasks is demonstrated, and they can retain the memory of the correct choice during a travel time of several seconds. Expand
Sophisticated Euclidean maps in forest chimpanzees
We examined the spatial orientation abilities of wild chimpanzees, Pan troglodytes verus, in Tai National Park, Cote d'Ivoire. Predictions resulting from the hypothesized use of topological maps andExpand
Chimpanzees using stones to crack open oil palm nuts in Liberia
The use of stone-tools to open palm nuts (Elaeis guineensis) was studied in a group of 16 chimpanzees (Pan troglodytes) released from captivity to a natural island setting in Liberia. The behaviourExpand
Distance-decay effect in stone tool transport by wild chimpanzees
Using hammerstones left behind at chimpanzee Panda nut-cracking sites, a distance-decay effect is found, in which the weight of material decreases with increasing distance from raw material sources, which provides a relevant analogy for understanding the formation of hominin landscapes. Expand
Percussive tool use by Taï Western chimpanzees and Fazenda Boa Vista bearded capuchin monkeys: a comparison
The ecological settings in which nut-cracking occurs are described and four aspects of nut-Cracking that have important cognitive implications are focused on, namely selection of tools, tool transport, tool modification and modulation of actions to reach the goal of cracking the nut. Expand
Flexibility of wild chimpanzee nut-cracking behavior using stone hammers and anvils : an experimental analysis
Nut-cracking behavior in wild chimpanzees (Pan troglodytes verus) using natural stone hammers and anvils was studied through transect survey and experimental analysis at Bossu, Guinea. TransectExpand


Sex differences in the use of natural hammers by wild chimpanzees: A preliminary report
The chimpanzees of the Tai National Park, Ivory Coast, use clubs and stones to open different species of nuts. An intriguing sex difference has been observed in this behavior. It is almostExpand
Optimisation of Nut-Cracking With Natural Hammers By Wild Chimpanzees
The chimpanzees of the Tai National Park, Ivory Coast, use sticks and stones to open 5 different species of nuts. In spite of an unfavourable availability of the material in the forest, the animalsExpand
Possible causes of sex differences in the use of natural hammers by wild chimpanzees
The analysis of 5 hypotheses stresses the role of the difference of sociability and sexual dimorphism between the sexes, both negatively affecting the nut-cracking techniques and performance of the adult males, on the evolution of the division of labor and food-sharing in the chimpanzee and in early hominids.

Multiple classification performance of juvenile chimpanzees, normal children, and retarded children
The cognitive capacities of juvenile chimpanzees, normal children, and retarded children were evaluated by using a nonverbal, Piagetian-type multiple classification task. The three groups of subjectsExpand
Concrete Operational Development in Three Cultures
Berry's (1971) model of ecological functionalism is extended to Piagetian developmental psychology. It is predicted that the rate of development of concrete operations may be partly determined byExpand
Conservation of Liquid and Solid Quantity by the Chimpanzee
Control tests showed that Sarah, an adult "language"-trained chimpanzee, made accurate same-different judgments on quantities of liquid and solid matter and conserved both types of quantity despite a transformation in an irrelevant property (shape). Expand
Chimpanzee Spatial Memory Organization
Juvenile chimpanzees, carried around an outdoor field and shown up to 18 randomly placed hidden foods, remembered most of these hiding places and the type of food that was in each. Their searchExpand
