	Title	*Interplay between environmental and genetic factors in temperament/personality traits in horses (Equus caballus)*			Type	Journal Article
	Year	2004	Publication	Journal of Comparative Psychology	Abbreviated Journal	J Comp Psychol
	Volume	118	Issue	4	Pages	434-446
	Keywords	Affect; Animals; Behavior, Animal/physiology; Environment; Female; Horses/psychology; Learning; Male; Memory/physiology
	Abstract	The aim of the present study was to broach the question of the relative influence of different genetic and environmental factors on different temperament/personality traits of horses (Equus caballus). The researchers submitted 702 horses to standardized experimental tests and investigated 9 factors, either genetic or environmental. Genetic factors, such as sire or breed, seemed to influence more neophobic reactions, whereas environmental factors, such as the type of work, seemed to play a more dominant role in reactions to social separation or learning abilities. Additive effects were evident, showing how environmental factors may modulate behavioral traits. This study constitutes a first step toward understanding the relative weights of genetic factors and how the environment may intervene in determining individual behavioral characteristics.

	Title	Learning and satiation of response in intrinsically motivated complex puzzle performance by monkeys			Type	Journal Article
	Year	1950	Publication	Journal of Comparative and Physiological Psychology	Abbreviated Journal	J Comp Physiol Psychol
	Volume	43	Issue	4	Pages	289-294
	Keywords	Animals; Haplorhini; Learning; Motivation; Psychology; Satiation; Learning; Motivation; Psychology
	Abstract	Two rhesus monkeys, given 60 two-hour sessions with a six-device mechanical puzzle showed clear evidence of learning, the curve showing ratio of incorrect to correct responses appearing quite comparable to similar curves obtained during externally rewarded situations. When, on the thirteenth day of tests, the subjects were presented with the puzzle 100 times at 6-minute intervals, the number of devices manipulated decreased regularly throughout the day, although there was no significant change in the number of times the problem assembly was attacked.

	Title	How do apes ape?			Type	Journal Article
	Year	2004	Publication	Learning & Behavior	Abbreviated Journal	Learn. Behav.
	Volume	32	Issue	1	Pages	36-52
	Keywords	Adaptation, Psychological; Animals; Behavior, Animal; Hominidae/psychology; Imitative Behavior; Imprinting (Psychology); Learning; Psychological Theory; Social Environment; *Social Facilitation
	Abstract	In the wake of telling critiques of the foundations on which earlier conclusions were based, the last 15 years have witnessed a renaissance in the study of social learning in apes. As a result, we are able to review 31 experimental studies from this period in which social learning in chimpanzees, gorillas, and orangutans has been investigated. The principal question framed at the beginning of this era, Do apes ape? has been answered in the affirmative, at least in certain conditions. The more interesting question now is, thus, How do apes ape? Answering this question has engendered richer taxonomies of the range of social-learning processes at work and new methodologies to uncover them. Together, these studies suggest that apes ape by employing a portfolio of alternative social-learning processes in flexibly adaptive ways, in conjunction with nonsocial learning. We conclude by sketching the kind of decision tree that appears to underlie the deployment of these alternatives.

	Title	Testing for social learning and imitation in common marmosets, Callithrix jacchus, using an artificial fruit			Type	Journal Article
	Year	2004	Publication	Animal cognition	Abbreviated Journal	Anim. Cogn.
	Volume	7	Issue	2	Pages	77-85
	Keywords	Animals; Association Learning; Callithrix/psychology; Discrimination Learning; Feeding Behavior; Female; Food Preferences; Fruit; Imitative Behavior; Male; *Social Behavior; Social Environment
	Abstract	We tested for social learning and imitation in common marmosets using an artificial foraging task and trained conspecific demonstrators. We trained a demonstrator marmoset to open an artificial fruit, providing a full demonstration of the task to be learned. Another marmoset provided a partial demonstration, controlling for stimulus enhancement effects, by eating food from the outside of the apparatus. We thus compared three observer groups, each consisting of four animals: those that received the full demonstration, those that received the partial demonstration, and a control group that saw no demonstration prior to testing. Although none of the observer marmosets succeeded in opening the artificial fruit during the test periods, there were clear effects of demonstration type. Those that saw the full demonstration manipulated the apparatus more overall, whereas those from the control group manipulated it the least of the three groups. Those from the full-demonstration group also contacted the particular parts of the artificial fruit that they had seen touched (localised stimulus enhancement) to a greater extent than the other two groups. There was also an interaction between the number of hand and mouth touches made to the artificial fruit for the full- and partial-demonstration groups. Whether or not these data represent evidence for imitation is discussed. We also propose that the clear differences between the groups suggest that social learning mechanisms provide real benefits to these animals in terms of developing novel food-processing skills analogous to the one presented here.

	Title	*A gray seal's (Halichoerus grypus) responses to experimenter-given pointing and directional cues*			Type	Journal Article
	Year	2003	Publication	Journal of Comparative Psychology	Abbreviated Journal	J Comp Psychol
	Volume	117	Issue	4	Pages	355-362
	Keywords	Animals; Behavior, Animal/physiology; Cognition/physiology; Conditioning, Operant/physiology; Cues; Eye Movements/physiology; Female; Seals, Earless
	Abstract	A gray seal (Halichoerus grypus) was trained to touch a target on its left or right by responding to pointing signals. The authors then tested whether the seal would be able to generalize spontaneously to altered signals. It responded correctly to center pointing and head turning, center upper body turning, and off-center pointing but not to head turning and eye movements alone. The seal also responded correctly to brief ipsilateral and contralateral points from center and lateral positions. Pointing gestures did not cause the seal to select an object placed centrally behind it. Like many animals in similar studies, this gray seal probably did not understand the referential character of these gestures but rather used signal generalization and experience from initial operant conditioning to solve these tasks.

	Title	Risk factors associated with behavioural disorders of crib-biting, weaving and box-walking in Swiss horses			Type	Journal Article
	Year	2003	Publication	Equine Veterinary Journal	Abbreviated Journal	Equine Vet J
	Volume	35	Issue	2	Pages	158-163
	Keywords	Animal Husbandry/methods; Animals; Behavior, Animal; Confounding Factors (Epidemiology); Data Collection; Female; Horse Diseases/epidemiology/etiology/prevention & control; Horses; Housing, Animal; Male; Mental Disorders/epidemiology/etiology/prevention & control/veterinary; Prevalence; Regression Analysis; Risk Factors; Stereotyped Behavior; Switzerland/epidemiology
	Abstract	REASONS FOR PERFORMING STUDY: Studies on the prevalence of behavioural disorders in horses and on associated risk factors have revealed inconsistent results. There are many studies on the neuropharmacological, surgical or mechanical therapy of stereotypies, but little is known about their causation. OBJECTIVES: To explore risk factors associated with the occurrence of behavioural disorders in horses. METHODS: A sample of horse owners, selected randomly and representative for Switzerland, was contacted in a postal survey. Answers were provided for 622 stables (response rate 35.2%). Individual data of 2,341 horses were examined with path analysis (multivariable linear and logistic regression), and adjustment made for possible confounding effects due to age and breed. RESULTS: Out of 60 possible risk factors, 11 were associated with the outcome at the univariable level (null-hypothesis path model) and 3 factors remained after the backward logistic regression procedure. Mature Warmbloods and Thoroughbreds, assessed by the owners to be reactive, fed 4 times a day and without daily pasture, had increased odds of displaying crib-biting, weaving and box-walking. Furthermore, indirect associations of 5 factors with the outcome were identified. CONCLUSIONS: The final logistic regression model of risk factors leads to the hypotheses that causal prevention of stereotypic behaviours should be based upon housing and management conditions which allow tactile contact with other horses (e.g. mutual grooming), daily free movement (paddock or pasture), as well as the provision of high amounts of roughage but of little or no concentrates. POTENTIAL CLINICAL RELEVANCE: It is one of the aims of population medicine to prevent the development of behavioural disorders. Further research is needed to test the concluding hypotheses in experimental studies or to verify them in the context of similar observational studies.

	Title	*Differential use of vocal and gestural communication by chimpanzees (Pan troglodytes) in response to the attentional status of a human (Homo sapiens)*			Type	Journal Article
	Year	2001	Publication	Journal of Comparative Psychology	Abbreviated Journal	J. Comp. Psychol.
	Volume	115	Issue	4	Pages	337-343
	Keywords	Animals; Attention; Communication Methods, Total; Female; Gestures; Humans; Male; Motivation; Pan troglodytes/psychology; Social Environment; Species Specificity; *Vocalization, Animal
	Abstract	This study examined the communicative behavior of 49 captive chimpanzees (Pan troglodytes), particularly their use of vocalizations, manual gestures, and other auditory- or tactile-based behaviors as a means of gaining an inattentive audience's attention. A human (Homo sapiens) experimenter held a banana while oriented either toward or away from the chimpanzee. The chimpanzees' behavior was recorded for 60 s. Chimpanzees emitted vocalizations faster and were more likely to produce vocalizations as their 1st communicative behavior when a human was oriented away from them. Chimpanzees used manual gestures more frequently and faster when the human was oriented toward them. These results replicate the findings of earlier studies on chimpanzee gestural communication and provide new information about the intentional and functional use of their vocalizations.

	Title	Social complexity and social intelligence			Type	Conference Article
	Year	2000	Publication	Novartis Foundation Symposium	Abbreviated Journal	Novartis Found Symp
	Volume	233	Issue		Pages	185-96; discussion 196-201
	Keywords	Animals; Brain/anatomy & histology/physiology; Humans; Intelligence/physiology; Learning; Models, Psychological; Primates; *Social Behavior; Social Problems
	Abstract	When we talk of the 'nature of intelligence', or any other attribute, we may be referring to its essential structure, or to its place in nature, particularly the function it has evolved to serve. Here I examine both, from the perspective of the evolution of intelligence in primates. Over the last 20 years, the Social (or 'Machiavellian') Intelligence Hypothesis has gained empirical support. Its core claim is that the intelligence of primates is primarily an adaptation to the special complexities of primate social life. In addition to this hypothesis about the function of intellect, a secondary claim is that the very structure of intelligence has been moulded to be 'social' in character, an idea that presents a challenge to orthodox views of intelligence as a general-purpose capacity. I shall outline the principal components of social intelligence and the environment of social complexity it engages with. This raises the question of whether domain specificity is an appropriate characterization of social intelligence and its subcomponents, like theory of mind. As a counter-argument to such specificity I consider the hypothesis that great apes exhibit a cluster of advanced cognitive abilities that rest on a shared capacity for second-order mental representation.

	Title	Experimental evidence that group foragers can converge on predicted producer-scrounger equilibria			Type	Journal Article
	Year	2000	Publication	Animal Behaviour.	Abbreviated Journal	Anim. Behav.
	Volume	60	Issue	3	Pages	341-350
	Keywords
	Abstract	When foraging together, animals are often observed to feed from food discoveries of others. The producer-scrounger (PS) game predicts how frequently this phenomenon of food parasitism should occur. The game assumes: (1) at any moment all individuals can unambiguously be categorized as either playing producer (searching for undiscovered food resources) or scrounger (searching for exploitation opportunities), and (2) the payoffs received from the scrounger tactic are negatively frequency dependent; a scrounger does better than a producer when the scrounger tactic is rare, but worse when it is common. No study to date has shown that the payoffs of producer and scrounger conform to the game's assumptions or that groups of foragers reach the predicted stable equilibrium frequency (SEF) of scrounger, whereby both tactics obtain the same payoff. The current study of three captive flocks of spice finches, Lonchura punctulata, provides the first test of the PS game using an apparatus in which both assumptions of the PS game are met. The payoffs to the scrounger, measured as feeding rate (seeds/s), were highly negatively frequency dependent on the frequency of scrounger. The feeding rate for scrounger declined linearly while the rate for producer either declined only slightly or not at all with increasing scrounger frequency. When given the opportunity to alternate between tactics, the birds changed their use of each, such that the group converged on the predicted SEF of scrounger after 5-8 days of testing. Individuals in this study, therefore, demonstrated sufficient plasticity in tactic use such that the flock foraged at the SEF of scrounger.
