Young children spontaneously invent wild great apes' tool-use behaviours.
The variety and complexity of human-made tools are unique in the animal kingdom. Research investigating why human tool use is special has focused on the role of social learning: while non-human great apes acquire tool-use behaviours mostly by individual (re-)inventions, modern humans use imitation and teaching to accumulate innovations over time. However, little is known about tool-use behaviou...
متن کاملTool-Use by Great Apes in the Wild
Abstract Evidence for tool use and tool-making by great apes in the wild is contrasted against the earliest stone artifacts and signs of their use before 2 million years ago by hominins who had attained a cognitive capacity both to envisage how by manipulating one object they could modify another in order to transform it into a tool, and to remember the manual behavior required to carry out the...
متن کاملSequential Tool Use in Great Apes
Sequential tool use is defined as using a tool to obtain another non-food object which subsequently itself will serve as a tool to act upon a further (sub)goal. Previous studies have shown that birds and great apes succeed in such tasks. However, the inclusion of a training phase for each of the sequential steps and the low cost associated with retrieving the longest tools limits the scope of t...
متن کاملThe cognitive underpinnings of flexible tool use in great apes.
Nonhuman primates perform poorly in trap tasks, a benchmark test of causal knowledge in nonhuman animals. However, recent evidence suggests that when the confound of tool use is avoided, great apes' performance improves dramatically. In the present study, we examined the cognitive underpinnings of tool use that contribute to apes' poor performance in trap tasks. We presented chimpanzees (Pan tr...
متن کاملRational tool use and tool choice in human infants and great apes.
G. Gergely, H. Bekkering, and I. Király (2002) showed that 14-month-old infants imitate rationally, copying an adult's unusual action more often when it was freely chosen than when it was forced by some constraint. This suggests that infants understand others' intentions as rational choices of action plans. It is important to test whether apes also understand others' intentions in this way. In ...
