Title Whistle matching in wild bottlenose dolphins (Tursiops truncatus) Type Journal Article
Year 2000 Publication Science (New York, N.Y.) Abbreviated Journal Science
Volume 289 Issue 5483 Pages 1355-1357
Keywords Animals; Animals, Wild/physiology; Dolphins/*physiology; *Imitative Behavior; *Learning; *Social Behavior; *Vocalization, Animal
Abstract Dolphin communication is suspected to be complex, on the basis of their call repertoires, cognitive abilities, and ability to modify signals through vocal learning. Because of the difficulties involved in observing and recording individual cetaceans, very little is known about how they use their calls. This report shows that wild, unrestrained bottlenose dolphins use their learned whistles in matching interactions, in which an individual responds to a whistle of a conspecific by emitting the same whistle type. Vocal matching occurred over distances of up to 580 meters and is indicative of animals addressing each other individually.

Title Ordering of the numerosities 1 to 9 by monkeys Type Journal Article
Year 1998 Publication Science (New York, N.Y.) Abbreviated Journal Science
Volume 282 Issue 5389 Pages 746-749
Keywords Animals; *Discrimination (Psychology); Macaca mulatta/*psychology; *Mathematics; *Mental Processes
Abstract A fundamental question in cognitive science is whether animals can represent numerosity (a property of a stimulus that is defined by the number of discriminable elements it contains) and use numerical representations computationally. Here, it was shown that rhesus monkeys represent the numerosity of visual stimuli and detect their ordinal disparity. Two monkeys were first trained to respond to exemplars of the numerosities 1 to 4 in an ascending numerical order (1 --> 2 --> 3 --> 4). As a control for non-numerical cues, exemplars were varied with respect to size, shape, and color. The monkeys were later tested, without reward, on their ability to order stimulus pairs composed of the novel numerosities 5 to 9. Both monkeys responded in an ascending order to the novel numerosities. These results show that rhesus monkeys represent the numerosities 1 to 9 on an ordinal scale.

Title Cognitive imitation in rhesus macaques Type Journal Article
Year 2004 Publication Science (New York, N.Y.) Abbreviated Journal Science
Volume 305 Issue 5682 Pages 407-410
Keywords Animals; *Cognition; *Imitative Behavior; *Learning; Macaca mulatta/*physiology/psychology; Male
Abstract Experiments on imitation typically evaluate a student's ability to copy some feature of an expert's motor behavior. Here, we describe a type of observational learning in which a student copies a cognitive rule rather than a specific motor action. Two rhesus macaques were trained to respond, in a prescribed order, to different sets of photographs that were displayed on a touch-sensitive monitor. Because the position of the photographs varied randomly from trial to trial, sequences could not be learned by motor imitation. Both monkeys learned new sequences more rapidly after observing an expert execute those sequences than when they had to learn new sequences entirely by trial and error.
