	Title	Body orientation and face orientation: two factors controlling apes' behavior from humans			Type	Journal Article
	Year	2004	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	7	Issue	4	Pages	216-223
	Keywords	Animals; Attention; Behavior, Animal; Cognition; Concept Formation; Face; Facial Expression; Female; Fixation, Ocular; Hominidae/psychology; Humans; Male; Nonverbal Communication; Orientation; Pan paniscus/psychology; Pan troglodytes/psychology; Pongo pygmaeus/psychology; *Posture; Social Perception; Species Specificity
	Abstract	A number of animal species have evolved the cognitive ability to detect when they are being watched by other individuals. Precisely what kind of information they use to make this determination is unknown. There is particular controversy in the case of the great apes because different studies report conflicting results. In experiment 1, we presented chimpanzees, orangutans, and bonobos with a situation in which they had to request food from a human observer who was in one of various attentional states. She either stared at the ape, faced the ape with her eyes closed, sat with her back towards the ape, or left the room. In experiment 2, we systematically crossed the observer's body and face orientation so that the observer could have her body and/or face oriented either towards or away from the subject. Results indicated that apes produced more behaviors when they were being watched. They did this not only on the basis of whether they could see the experimenter as a whole, but they were sensitive to her body and face orientation separately. These results suggest that body and face orientation encode two different types of information. Whereas face orientation encodes the observer's perceptual access, body orientation encodes the observer's disposition to transfer food. In contrast to the results on body and face orientation, only two of the tested subjects responded to the state of the observer's eyes.

	Title	Direct observations of pandanus-tool manufacture and use by a New Caledonian crow (Corvus moneduloides)			Type	Journal Article
	Year	2004	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	7	Issue	2	Pages	114-120
	Keywords	Animals; Behavior, Animal; Discrimination Learning; Feeding Behavior; Functional Laterality; Manufactured Materials; Plant Leaves; Songbirds
	Abstract	New Caledonian crows are reported to have impressive pandanus-tool manufacture abilities. These claims are based on an extensive artefact record. However, inferring behavioural and cognitive abilities without direct observation of tool manufacture is problematic. Here we report (and document on video) direct observations of a crow making and using stepped pandanus tools at Pic Ningua. We observed (1) a bias for making tools on left edges consistent with that previously found at the site, (2) faithful manufacture of a stepped design with high overall congruence in the shapes of tools, (3) the use of convergent rips to first form the tapered end working away from the trunk then the wide end working towards the trunk, (4) appropriate functional use of stepped tools by use of the leaf-edge barbs to hook food from holes, and (5) consistent holding of tools on the left side of its head when using them. Our observations verify most of the claims based on the artefact record, but the crow's exact manufacture technique was slightly different to that inferred previously.

	Title	Public information: from nosy neighbors to cultural evolution			Type	Journal Article
	Year	2004	Publication	Science (New York, N.Y.)	Abbreviated Journal	Science
	Volume	305	Issue	5683	Pages	487-491
	Keywords	Animals; Behavior, Animal; Cues; Cultural Evolution; *Decision Making; Environment; Evolution; Feeding Behavior; Female; Genes; Humans; Male; Reproduction; Sexual Behavior, Animal
	Abstract	Psychologists, economists, and advertising moguls have long known that human decision-making is strongly influenced by the behavior of others. A rapidly accumulating body of evidence suggests that the same is true in animals. Individuals can use information arising from cues inadvertently produced by the behavior of other individuals with similar requirements. Many of these cues provide public information about the quality of alternatives. The use of public information is taxonomically widespread and can enhance fitness. Public information can lead to cultural evolution, which we suggest may then affect biological evolution.

	Title	Causes of natal dispersal and emigration and their effects on harem formation in Misaki feral horses			Type	Journal Article
	Year	1997	Publication	Equine Veterinary Journal	Abbreviated Journal	Equine Vet J
	Volume	29	Issue	4	Pages	262-266
	Keywords	Age Factors; Animal Migration; Animals; Animals, Wild; Behavior, Animal/physiology; Female; Horses/physiology/psychology; Male; Reproduction; Seasons; Sexual Behavior, Animal; *Social Behavior
	Abstract	Misaki feral horses were separated into 2 herds and the difference between dispersal from natal group (natal dispersal) and dispersal from natal area (natal emigration) was studied. The causes of dispersal and emigration and their effects on harem formation were studied 1979-1994. The number of horses ranged from 73 (mature males: 8, mature females: 26, young males: 8, young females: 3, colt foals: 6, filly foals: 10 and geldings: 12) in 1979 and 86 (mature males: 14, mature females: 37, young males: 12, young females: 7, colt foals: 5, filly foals: 7 and geldings: 4) in 1994 when the present study ended. All 29 males which survived to age 4 years and 58 females which survived to age 3 years left their natal or mother groups at age one to 3. Seventeen of 22 dispersing males and 29 of 39 dispersing females left their natal groups around the birth of their siblings and significant correlations were found between natal dispersal and birth of a sibling. The number of emigrating young males correlated negatively and significantly with the total number of young males in another herd and the number of emigrating young females correlated positively and significantly with the total number of young females in the natal herd. All 13 emigrating stallions which survived to age 5 years formed stable harem groups and a significant correlation was found between natal emigration and harem formation. Twenty-three of 35 resident mares formed stable consort relations with harem stallions and a significant correlation was found between residence and formation of stable consort relations.

	Title	Animal expertise, conscious or not			Type	Journal Article
	Year	2005	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	8	Issue	2	Pages	67-74
	Keywords	Animals; Behavior, Animal; Cognition; Consciousness; Learning; Motor Skills; *Practice (Psychology)
	Abstract	Rossano (Cognition 89:207, 2003) proposes expertise as an indicator of consciousness in humans and other animals. Since there is strong evidence that the development of expertise requires deliberate practice (Ericsson in The road to excellence: the acquisition of expert performance in the arts and sciences, sports and games 1996), and deliberate practice appears to be outside of the bounds of unconscious processing, then any signs of expertise development in an animal are indicators of consciousness. Rossano's argument may lead to an unsolvable debate about animal consciousness while causing researchers to overlook the underlying reality of animal expertise. This article provides evidence indicative of animals meeting each of the three definitions of expertise established in the scientific literature: expertise as a social construction, expertise as exceptional performance, and expertise as knowledge. In addition, cases of deliberate practice by non-human animals are offered. Acknowledging some animals as experts, regardless of consciousness, is warranted by the research findings and would prove useful in solving many issues remaining in the human expertise literature.

	Title	Tool-use learning in Tonkean macaques (Macaca tonkeana)			Type	Journal Article
	Year	2005	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	8	Issue	2	Pages	103-113
	Keywords	Animals; Association Learning; Behavior, Animal; Cognition; Imitative Behavior; Intelligence; Macaca/psychology; Male; *Motor Skills
	Abstract	The transmission of tool use is a rare event in monkeys. Such an event arose in a group of semi-free-ranging Tonkean macaques (Macaca tonkeana) in which leaning a pole against the park's fence (branch leaning) appeared and spread to several males. This prompted us to test individual and social learning of this behavior in seven young males. In the first experiment, three males learned individually to obtain a food reward using a wooden pole as a climbing tool. They began using the pole to retrieve the reward only when they could alternatively experience acting on the object and reaching the target. In a second experiment, we first tested whether four other subjects could learn branch leaning after having observed a group-mate performing the task. Despite repeated opportunities to observe the demonstrator, they did not learn to use the pole as a tool. Hence we exposed the latter subjects to individual learning trials and they succeeded in the task. Tool use was not transmitted in the experimental situation, which contrasts with observations in the park. We can conclude that the subjects were not able to recognize the target as such. It is possible that they recognized it and learned the task individually when we alternated the opportunity to act upon the object and to reach the reward. This suggests that these macaques could then have associated the action they exercised upon the pole and the use of the pole as a means to reach the reward.

	Title	Functional equivalence in pigeons involving a four-member class			Type	Journal Article
	Year	2004	Publication	Behavioural processes	Abbreviated Journal	Behav. Process.
	Volume	67	Issue	3	Pages	395-403
	Keywords	Animals; Association Learning; Behavior, Animal; Cognition; Columbidae; Concept Formation
	Abstract	Research suggests that animals are capable of forming functional equivalence relations or stimulus classes of the kind usually demonstrated by humans (e.g., the class defined by an object and the word for that object). In pigeons, such functional equivalences are typically established using many-to-one matching-to-sample in which two samples are associated with one comparison stimulus and two different samples are associated with the other. Evidence for the establishment of functional equivalences between samples associated with the same comparison comes from transfer tests. In Experiment 1, we found that pigeons can form a single class consisting of four members (many-to-one matching) when the alternative class has only one member (one-to-one matching). In Experiment 2, we ruled out the possibility that the pigeons acquired the hybrid one-to-one/many-to-one task by developing a single-code/default coding strategy as earlier research suggested that it might. Thus, pigeons can develop a functional class consisting of as many as four members, with the alternative class consisting of a single member.

	Title	Pigeons shift their preference toward locations of food that take more effort to obtain			Type	Journal Article
	Year	2004	Publication	Behavioural processes	Abbreviated Journal	Behav. Process.
	Volume	67	Issue	3	Pages	405-415
	Keywords	Animals; Behavior, Animal; Choice Behavior; Columbidae; Exertion; Feeding Behavior; Reward
	Abstract	Although animals typically prefer to exert less effort rather than more effort to obtain food, the present research shows that requiring greater effort to obtain food at a particular location appears to increase the value of that location. In Experiment 1, pigeons' initial preference for one feeder was significantly reduced by requiring 1 peck to obtain food from that feeder and requiring 30 pecks to obtain food from the other feeder. In Experiment 2, a similar decrease in preference was not found when pigeons received reinforcement from both feeders independently of the amount of effort required. These results are consistent with the within-trial contrast effect proposed by in which the relative hedonic value of a reward depends on the state of the animal immediately prior to the reward. The greater the improvement from that prior state the greater the value of the reinforcer.
