Animal Cognition: Crows Spontaneously Solve a Metatool Task
نویسنده
چکیده
A recent study found that tool-manufacturing New Caledonian crows spontaneously solved a metatool task in which the birds used a tool to obtain a second, longer tool that could then be used to obtain food that was otherwise out of reach.

Spontaneous Metatool Use by New Caledonian Crows
A crucial stage in hominin evolution was the development of metatool use -- the ability to use one tool on another [1, 2]. Although the great apes can solve metatool tasks [3, 4], monkeys have been less successful [5-7]. Here we provide experimental evidence that New Caledonian crows can spontaneously solve a demanding metatool task in which a short tool is used to extract a longer tool that ca...
متن کاملComplex cognition and behavioural innovation in New Caledonian crows.
Apes, corvids and parrots all show high rates of behavioural innovation in the wild. However, it is unclear whether this innovative behaviour is underpinned by cognition more complex than simple learning mechanisms. To investigate this question we presented New Caledonian crows with a novel three-stage metatool problem. The task involved three distinct stages: (i) obtaining a short stick by pul...
متن کاملModifications to the Aesop's Fable Paradigm Change New Caledonian Crow Performances
While humans are able to understand much about causality, it is unclear to what extent non-human animals can do the same. The Aesop's Fable paradigm requires an animal to drop stones into a water-filled tube to bring a floating food reward within reach. Rook, Eurasian jay, and New Caledonian crow performances are similar to those of children under seven years of age when solving this task. Howe...
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 کاملInside the corvid brain—probing the physiology of cognition in crows
categories Rather than representing each detail of a sensory stimulus, the classification of stimuli into behaviorally meaningful categories endows animals with superior behavioral flexibility. Classifying items according to their number is a particular abstract category. It allows animals to abstract from the sensory attributes of elements to arrive at the quantitative category ‘numerosity’. E...
