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 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 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 کاملAn end to insight? New Caledonian crows can spontaneously solve problems without planning their actions.
Animals rarely solve problems spontaneously. Some bird species, however, can immediately find a solution to the string-pulling problem. They are able to rapidly gain access to food hung on the end of a long string by repeatedly pulling and then stepping on the string. It is currently unclear whether these spontaneous solutions are produced by insight or by a perceptual-motor feedback loop. Here...
متن کاملHow New Caledonian crows solve novel foraging problems and what it means for cumulative culture.
New Caledonian crows make and use tools, and tool types vary over geographic landscapes. Social learning may explain the variation in tool design, but it is unknown to what degree social learning accounts for the maintenance of these designs. Indeed, little is known about the mechanisms these crows use to obtain information from others, despite the question's importance in understanding whether...
