New Caledonian crows (Corvus moneduloides) are the most prolific avian tool-users. Regional variation in the shape of their tools may be the result of cumulative cultural evolution--a phenomenon considered to be a hallmark of human culture. Here we show that hand-raised juvenile New Caledonian crows spontaneously manufacture and use tools, without any(More)
New Caledonian crows, Corvus moneduloides, are the most advanced avian tool makers and tool users. We previously reported that captive-bred isolated New Caledonian crows spontaneously use twig tools and cut tools out of Pandanus spp. tree leaves, an activity possibly under cultural influence in the wild. However, what aspects of these behaviours are(More)
We studied laterality of tool use in 10 captive New Caledonian (NC) crows (Corvus moneduloides). All subjects showed near-exclusive individual laterality, but there was no overall bias in either direction (five were left-lateralized and five were right-lateralized). This is consistent with results in non-human primates, which show strong individual(More)
Introduction In the semi-tropical rain forest of the Pacific islands of New Caledonia, a crow detects the presence of a succulent grub (a beetle larva) deep in an inaccessible burrow in a tree. It Kacelnik et al. New Caledonian crow cognition Wasserman & Zentall chapter 12/10/04 page 2 flies to a nearby tree, breaks off a small branch and removes leaves and(More)
In this article we propose a computational model that describes how observed behavior can influence an observer's own behavior, including the acquisition of new task descriptions. The sources of influence on our model's behavior are: beliefs about the world's possible states and actions causing transitions between them; baseline preferences for certain(More)
In this paper we propose a computational model for learning from demonstration. By adequate adjustment of a few parameters, our model is able to produce dierent learning behaviours, taking into account dierent elements of the demonstration. In particular, our model takes into consideration the actions of the demonstrator, its eects on the(More)
Cognitive Foundations of Cultural Learning The ability to learn from others is integral to sustaining and transmitting human culture. What are the cognitive processes that support imitative and collaborative cultural learning? How does cultural learning contribute to group dynamics, such as cohesion and conflict? Recent research has focused on how children(More)
