Do new caledonian crows solve physical problems through causal reasoning?
The extent to which animals other than humans can reason about physical problems is contentious. The benchmark test for this ability has been the trap-tube task. We presented New Caledonian crows with a series of two-trap versions of this problem. Three out of six crows solved the initial trap-tube. These crows continued to avoid the trap when the arbitrary features that had previously been ass...
متن کاملCausal reasoning in New Caledonian crows: Ruling out spatial analogies and sampling error.
A large number of studies have failed to find conclusive evidence for causal reasoning in nonhuman animals. For example, when animals are required to avoid a trap while extracting a reward from a tube they appear to learn about the surface-level features of the task, rather than about the task's causal regularities. We recently reported that New Caledonian crows solved a two-trap-tube task and ...
متن کاملHow New Caledonian crows solve
16 New Caledonian crows make and use tools and tool types vary over geographic landscapes. Social 17 learning may explain the variation in tool design, but it is unknown to what degree social learning 18 accounts for the maintenance of these designs. Indeed, little is known about the mechanisms these 19 crows use to obtain information from others, despite the question’s importance in understand...
متن کاملSocial learning in New Caledonian crows.
New Caledonian (NC) crows are the most sophisticated tool manufacturers other than humans. The diversification and geographical distribution of their three Pandanus tool designs that differ in complexity, as well as the lack of ecological correlates, suggest that cumulative technological change has taken place. To investigate the possibility that high-fidelity social transmission mediated this ...
متن کاملParallel tool industries in New Caledonian crows.
Individual specialization in the use of foraging tools occurs in hunter-gatherer societies but is absent in non-human primate tool use. 'Parallel tool industries' in hunter-gatherers are mainly based on strict sexual division of labour that is highly reliant on social conformity. Here, we show that 12 individuals in a population of New Caledonian crows on Maré Island had strong preferences for ...
