	Title	*Cross-modal individual recognition in domestic horses (Equus caballus)*			Type	Journal Article
	Year	2009	Publication	Proceedings of the National Academy of Sciences of the United States of America	Abbreviated Journal	Proc. Natl. Acad. Sci. U.S.A.
	Volume	106	Issue	3	Pages	947-951
	Keywords	animal cognition vocal communication social behavior playback experiment expectancy violation
	Abstract	Individual recognition is considered a complex process and, although it is believed to be widespread across animal taxa, the cognitive mechanisms underlying this ability are poorly understood. An essential feature of individual recognition in humans is that it is cross-modal, allowing the matching of current sensory cues to identity with stored information about that specific individual from other modalities. Here, we use a cross-modal expectancy violation paradigm to provide a clear and systematic demonstration of cross-modal individual recognition in a nonhuman animal: the domestic horse. Subjects watched a herd member being led past them before the individual went of view, and a call from that or a different associate was played from a loudspeaker positioned close to the point of disappearance. When horses were shown one associate and then the call of a different associate was played, they responded more quickly and looked significantly longer in the direction of the call than when the call matched the herd member just seen, an indication that the incongruent combination violated their expectations. Thus, horses appear to possess a cross-modal representation of known individuals containing unique auditory and visual/olfactory information. Our paradigm could provide a powerful way to study individual recognition across a wide range of species.

	Title	Cognitive neuroscience of human social behaviour			Type	Journal Article
	Year	2003	Publication	Nature Reviews. Neuroscience	Abbreviated Journal	Nat Rev Neurosci
	Volume	4	Issue	3	Pages	165-178
	Keywords	Cognition; Emotions; Humans; Models, Psychological; *Social Behavior
	Abstract	We are an intensely social species--it has been argued that our social nature defines what makes us human, what makes us conscious or what gave us our large brains. As a new field, the social brain sciences are probing the neural underpinnings of social behaviour and have produced a banquet of data that are both tantalizing and deeply puzzling. We are finding new links between emotion and reason, between action and perception, and between representations of other people and ourselves. No less important are the links that are also being established across disciplines to understand social behaviour, as neuroscientists, social psychologists, anthropologists, ethologists and philosophers forge new collaborations.

	Title	*Comprehension of human communicative signs in pet dogs (Canis familiaris)*			Type	Journal Article
	Year	2001	Publication	Journal of Comparative Psychology (Washington, D.C. : 1983)	Abbreviated Journal	J Comp Psychol
	Volume	115	Issue	2	Pages	122-126
	Keywords	Animals; Behavior, Animal; Choice Behavior; Dogs/psychology; Female; Humans; Male; Nonverbal Communication/psychology; Recognition (Psychology); *Social Behavior
	Abstract	On the basis of a study by D. J. Povinelli, D. T. Bierschwale, and C. G. Cech (1999), the performance of family dogs (Canis familiaris) was examined in a 2-way food choice task in which 4 types of directional cues were given by the experimenter: pointing and gazing, head-nodding (“at target”), head turning above the correct container (“above target”), and glancing only (“eyes only”). The results showed that the performance of the dogs resembled more closely that of the children in D. J. Povinelli et al.'s study, in contrast to the chimpanzees' performance in the same study. It seems that dogs, like children, interpret the test situation as being a form of communication. The hypothesis is that this similarity is attributable to the social experience and acquired social routines in dogs because they spend more time in close contact with humans than apes do, and as a result dogs are probably more experienced in the recognition of human gestures.

	Title	Behaviour of foals before weaning may have some genetic basis			Type	Journal Article
	Year	1994	Publication	Ethology	Abbreviated Journal	Ethology

	Keywords	Locomotion; Suckling; Social behavior; Foraging behavior; Exploratory behavior; Interindividual comparison; Young animal; Genetic inheritance; Captivity; Social interaction; Feeding behavior; Perissodactyla; Ungulata; Mammalia; Vertebrata
	Abstract	In this preliminary study on foal behaviour, 13 French saddlebred foals (2-3 mo old) and their dams were observed on pasture. The most important findings are the interindividual quantitative differences in foal behaviour patterns as well as in the amount of mainly foal-initiated time spent at given distances from their mares. Interindividual differences seem in part due to a sire effect

	Title	Capuchin monkeys (Cebus apella) are sensitive to others’ reward: an experimental analysis of food-choice for conspecifics			Type	Journal Article
	Year	2010	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	13	Issue	2	Pages	249-261
	Keywords	Other-regarding preference – Prosocial behavior – Inequity aversion – Food sharing – Social sensitivity – Capuchin monkeys
	Abstract	Abstract The issue whether non-human primates have other-regarding preference and/or inequity aversion has been under debate. We investigated whether tufted capuchin monkeys are sensitive to others’ reward in various experimental food sharing settings. Two monkeys faced each other. The operator monkey chose one of two food containers placed between the participants, each containing a food item for him/herself and another for the recipient. The recipient passively received either high- or low-value food depending on the operator’s choice, whereas the operator obtained the same food regardless of his/her choice. The recipients were either the highest- or lowest-ranking member of the group, and the operators were middle-ranking. In Experiment 1, the operators chose the high-value food for the subordinate recipient more frequently than when there was no recipient, whereas they were indifferent in their choice for the dominant. This differentiated behavior could have been because the dominant recipient frequently ate the low-value food. In Experiment 2, we increased the difference in the value of the two food items so that both recipients would reject the low-value food. The results were the same as in Experiment 1. In Experiment 3, we placed an opaque screen in front of the recipient to examine effects of visual contact between the participants. The operators’ food choice generally shifted toward providing the low-value food for the recipient. These results suggest that capuchins are clearly sensitive to others’ reward and that they show other-regarding preference or a form of inequity aversion depending upon the recipients and the presence of visual contact.

	Title	Social feedback and the emergence of leaders and followers			Type	Journal Article
	Year	2009	Publication	Current Biology : CB	Abbreviated Journal	Curr Biol
	Volume	19	Issue	3	Pages	248-252
	Keywords	Analysis of Variance; Animals; Appetitive Behavior/physiology; Feedback; Great Britain; Leadership; Markov Chains; Models, Biological; Monte Carlo Method; Smegmamorpha/physiology; Social Behavior; Video Recording
	Abstract	In many animal groups, certain individuals consistently appear at the forefront of coordinated movements [1-4]. How such leaders emerge is poorly understood [5, 6]. Here, we show that in pairs of sticklebacks, Gasterosteus aculeatus, leadership arises from individual differences in the way that fish respond to their partner's movements. Having first established that individuals differed in their propensity to leave cover in order to look for food, we randomly paired fish of varying boldness, and we used a Markov Chain model to infer the individual rules underlying their joint behavior. Both fish in a pair responded to each other's movements-each was more likely to leave cover if the other was already out and to return if the other had already returned. However, we found that bolder individuals displayed greater initiative and were less responsive to their partners, whereas shyer individuals displayed less initiative but followed their partners more faithfully; they also, as followers, elicited greater leadership tendencies in their bold partners. We conclude that leadership in this case is reinforced by positive social feedback.

	Title	Group decision-making in animals			Type	Journal Article
	Year	2003	Publication	Nature	Abbreviated Journal	Nature
	Volume	421	Issue	6919	Pages	155-158
	Keywords	Animals; Behavior, Animal/physiology; Decision Making; Democracy; Group Processes; *Models, Biological; Population Density; Social Behavior
	Abstract	Groups of animals often need to make communal decisions, for example about which activities to perform, when to perform them and which direction to travel in; however, little is known about how they do so. Here, we model the fitness consequences of two possible decision-making mechanisms: 'despotism' and 'democracy'. We show that under most conditions, the costs to subordinate group members, and to the group as a whole, are considerably higher for despotic than for democratic decisions. Even when the despot is the most experienced group member, it only pays other members to accept its decision when group size is small and the difference in information is large. Democratic decisions are more beneficial primarily because they tend to produce less extreme decisions, rather than because each individual has an influence on the decision per se. Our model suggests that democracy should be widespread and makes quantitative, testable predictions about group decision-making in non-humans.

	Title	Spontaneous emergence of leaders and followers in foraging pairs			Type	Journal Article
	Year	2003	Publication	Nature	Abbreviated Journal	Nature
	Volume	423	Issue	6938	Pages	432-434
	Keywords	Animals; Energy Metabolism; Food; Food Chain; Models, Biological; Motor Activity; Social Behavior; Time Factors
	Abstract	Animals that forage socially often stand to gain from coordination of their behaviour. Yet it is not known how group members reach a consensus on the timing of foraging bouts. Here we demonstrate a simple process by which this may occur. We develop a state-dependent, dynamic game model of foraging by a pair of animals, in which each individual chooses between resting or foraging during a series of consecutive periods, so as to maximize its own individual chances of survival. We find that, if there is an advantage to foraging together, the equilibrium behaviour of both individuals becomes highly synchronized. As a result of this synchronization, differences in the energetic reserves of the two players spontaneously develop, leading them to adopt different behavioural roles. The individual with lower reserves emerges as the 'pace-maker' who determines when the pair should forage, providing a straightforward resolution to the problem of group coordination. Moreover, the strategy that gives rise to this behaviour can be implemented by a simple 'rule of thumb' that requires no detailed knowledge of the state of other individuals.

	Title	Stress, social behavior, and resilience: Insights from rodents			Type	Journal Article
	Year	2015	Publication	Neurobiology of Stress	Abbreviated Journal	Neurobiol. Stress
	Volume	1	Issue	Stress Resilience	Pages	116-127
	Keywords	Stress; Anxiety; Social behavior; Sociality; Social stress; Social buffering
	Abstract	The neurobiology of stress and the neurobiology of social behavior are deeply intertwined. The social environment interacts with stress on almost every front: social interactions can be potent stressors; they can buffer the response to an external stressor; and social behavior often changes in response to stressful life experience. This review explores mechanistic and behavioral links between stress, anxiety, resilience, and social behavior in rodents, with particular attention to different social contexts. We consider variation between several different rodent species and make connections to research on humans and non-human primates.

	Title	Neuropeptidergic regulation of affiliative behavior and social bonding in animals			Type	Journal Article
	Year	2006	Publication	Hormones and Behavior	Abbreviated Journal	Hormon. Behav.
	Volume	50	Issue	4	Pages	506-517
	Keywords	Vasopressin receptor; Oxytocin receptor; Social recognition; Social behavior; Pair bond; Autism; Neuropeptides
	Abstract	Social relationships are essential for maintaining human mental health, yet little is known about the brain mechanisms involved in the development and maintenance of social bonds. Animal models are powerful tools for investigating the neurobiological mechanisms regulating the cognitive processes leading to the development of social relationships and for potentially extending our understanding of the human condition. In this review, we discuss the roles of the neuropeptides oxytocin and vasopressin in the regulation of social bonding as well as related social behaviors which culminate in the formation of social relationships in animal models. The formation of social bonds is a hierarchical process involving social motivation and approach, the processing of social stimuli and formation of social memories, and the social attachment itself. Oxytocin and vasopressin have been implicated in each of these processes. Specifically, these peptides facilitate social affiliation and parental nurturing behavior, are essential for social recognition in rodents, and are involved in the formation of selective mother-infant bonds in sheep and pair bonds in monogamous voles. The convergence of evidence from these animal studies makes oxytocin and vasopressin attractive candidates for the neural modulation of human social relationships as well as potential therapeutic targets for the treatment of psychiatric disorders associated with disruptions in social behavior, including autism.
