	Title	Effects of observational learning on food selection in horses			Type	Journal Article
	Year	1996	Publication	Applied Animal Behaviour Science	Abbreviated Journal	Appl. Anim. Behav. Sci.
	Volume	50	Issue	2	Pages	177-184
	Keywords	Horse; Observational learning; Food discrimination
	Abstract	Fourteen riding horses of mixed age and breed were randomly allocated to observer and control treatments. An additional horse was pre-trained as a demonstrator to walk the 13.8 m length of the test arena and select one of two food buckets using colour and pattern cues. Observer horses were exposed to correct performances of the task by the trained demonstrator, for 20 trials held over 2 days. Control horses were subjected to the same handling and placement procedures as the observer horses but without exposure to the behaviour of the demonstrator. The third day for all subjects was designated as a test day. Each subject was released individually in a predetermined place in the arena, and the latency to walk the length of the test arena to the food buckets, the latency to feed, the identity of the bucket approached and the identity of the bucket selected were recorded on ten consecutive trials. During tests both food buckets contained food to minimize the possibility of individual trial and error learning. On the first trial the mean latency to approach the goal area was 18 s for observer horses, compared with 119 s for control horses (t = 2.8, d.f. = 12, P < 0.01) and the mean latency to eat was 35 s for observer horses, compared with 181 s for control horses (t = 4.86, d.f. = 11, P < 0.001). However, observer horses were no more likely to choose the demonstrated bucket than control horses on the first trial. Twelve of the 14 horses decreased their latency to approach the goal area during the series of ten trials, but there were no significant changes in the buckets selected.

	Title	How animals learn from each other			Type	Journal Article
	Year	2006	Publication	Applied Animal Behaviour Science	Abbreviated Journal	Appl. Anim. Behav. Sci.
	Volume	100	Issue	1-2	Pages	58-63
	Keywords	Social learning; Chickens; Demonstrators; Dominance
	Abstract	This paper explores ways by which animals may learn from one another, using examples drawn mostly from the chicken, an animal for which social learning is likely to be less dangerous than individual learning. In early life, the behaviour of the hen is important in encouraging chicks to peck at edible items. Maternal display not only attracts chicks to profitable food items, but also redirects their attention away from harmful or non-profitable items. Older chicks can enhance their foraging success by observing the behaviour of conspecifics within their own social group. Hens have been trained to perform a novel behaviour (key-pecking for food) by observation of a trained demonstrator bird. Moreover, observers learnt most from watching dominant demonstrators. Thus the ability to learn from others is not `fixed', but depends on the context and the social identity of both the observer and the demonstrator.

	Title	The social transmission of information and behaviour			Type	Journal Article
	Year	1995	Publication	Applied Animal Behaviour Science	Abbreviated Journal	Appl. Anim. Behav. Sci.
	Volume	44	Issue	2-4	Pages	79-98
	Keywords	Social learning; Imitation; Social facilitation; Cultural transmission; Stereotypies
	Abstract	Social influences on established behaviour and on the acquisition of new information and behaviour are reviewed. Distinctions between social facilitation and contagious behaviour are drawn and suggestions for further research on contagious behaviour are made. Socially derived visual, olfactory and auditory cues are considered as important influences on behaviour and subsequent learning. The evidence supporting two potential mechanisms of social learning, i.e. stimulus enhancement followed by individual learning, and imitation, is reviewed in detail. It is argued that the functions of social learning are similarly heterogeneous and include motor skill acquisition, gathering of environmental information, and social conformity. Factors affecting the spread of socially acquired skills, including the social relationship between demonstrator and observer, are highlighted. Lastly, the few studies of social learning that have been conducted with domestic species are reviewed and potential applied goals that could stimulate further research in this area are suggested.

	Title	Cognitive and Communicative Abilities of Grey Parrots			Type	Journal Article
	Year	2002	Publication	Current Directions in Psychological Science	Abbreviated Journal	Curr. Dir. Psychol. Sci.
	Volume	11	Issue	3	Pages	83-87
	Keywords
	Abstract	Grey parrots (Psittacus erithacus) solve various cognitive tasks and acquire and use English speech in ways that often resemble those of very young children. Given that the psittacine brain is organized very differently from that of mammals, these results have intriguing implications for the study and evolution of vocal learning, communication, and cognition.

	Title	Realized heritability of personalities in the great tit (Parus major)			Type	Journal Article
	Year	2003	Publication	Proceedings. Biological sciences / The Royal Society	Abbreviated Journal	Proc Biol Sci
	Volume	270	Issue	1510	Pages	45-51
	Keywords	Aggression; Animals; Animals, Domestic; Animals, Wild; Behavior, Animal; Breeding; Exploratory Behavior; Female; Heredity; Male; Selection (Genetics); Songbirds/genetics/physiology; Variation (Genetics)
	Abstract	Behaviour under conditions of mild stress shows consistent patterns in all vertebrates: exploratory behaviour, boldness, aggressiveness covary in the same way. The existence of highly consistent individual variation in these behavioural strategies, also referred to as personalities or coping styles, allows us to measure the behaviour under standardized conditions on birds bred in captivity, link the standardized measurements to the behaviour under natural conditions and measure natural selection in the field. We have bred the great tit (Parus major), a classical model species for the study of behaviour under natural conditions, in captivity. Here, we report a realized heritability of 54 +/- 5% for early exploratory behaviour, based on four generations of bi-directional artificial selection. In addition to this, we measured hand-reared juveniles and their wild-caught parents in the laboratory. The heritability found in the mid-offspring-mid-parent regression was significantly different from zero. We have thus established the presence of considerable amounts of genetic variation for personality types in a wild bird.

	Title	The domestication of social cognition in dogs			Type	Journal Article
	Year	2002	Publication	Science (New York, N.Y.)	Abbreviated Journal	Science
	Volume	298	Issue	5598	Pages	1634-1636
	Keywords	Animals; Animals, Domestic; Behavior, Animal; Cognition; Cues; Dogs; Food; Humans; Memory; Pan troglodytes; Social Behavior; Species Specificity; Vision; Wolves
	Abstract	Dogs are more skillful than great apes at a number of tasks in which they must read human communicative signals indicating the location of hidden food. In this study, we found that wolves who were raised by humans do not show these same skills, whereas domestic dog puppies only a few weeks old, even those that have had little human contact, do show these skills. These findings suggest that during the process of domestication, dogs have been selected for a set of social-cognitive abilities that enable them to communicate with humans in unique ways.

	Title	Complex problem-solving: a field in search of a definition?			Type	Journal Article
	Year	2005	Publication	Theoretical Issues in Ergonomics Science	Abbreviated Journal	Theor Issues Ergon Sci
	Volume	6	Issue	1	Pages	5-33
	Keywords	Problem solving; Dynamic decision making; Micro-worlds; Expertise
	Abstract	Complex problem-solving (CPS) is as an area of cognitive science that has received a good amount of attention, but theories in the field have not progressed accordingly. The reasons could be the lack of good definitions and classifications of the tasks (taxonomies). Although complexity is a term used pervasively in psychology and is operationalized in different ways, there are no psychological theories of complexity. The definition of problem-solving has been changed in the past to reflect the varied interests of the researchers and has lost its initial concreteness. These two facts together make it difficult to define CPS or make clear if CPS should reuse the theory and methods of classical problem-solving or on the contrary should build a theoretical structure starting from scratch. A taxonomy is offered of tasks using both formal features and psychological features that are theory-independent that could help compare the CPS tasks used in the literature. The adequateness is also reviewed of the most extended definitions of CPS and conclude that they are in serious need of review, since they cover tasks that are not considered problem-solving by their own authors or are not complex, but ignore others that should clearly be included.

	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	The hippocampus and memory for orderly stimulus relations			Type	Journal Article
	Year	1997	Publication	Proceedings of the National Academy of Sciences of the United States of America	Abbreviated Journal	Proc. Natl. Acad. Sci. U.S.A.
	Volume	94	Issue	13	Pages	7109-7114
	Keywords	Animals; Attention; Discrimination (Psychology)/physiology; Hippocampus/anatomy & histology/physiology; Male; Memory/physiology; Rats
	Abstract	Human declarative memory involves a systematic organization of information that supports generalizations and inferences from acquired knowledge. This kind of memory depends on the hippocampal region in humans, but the extent to which animals also have declarative memory, and whether inferential expression of memory depends on the hippocampus in animals, remains a major challenge in cognitive neuroscience. To examine these issues, we used a test of transitive inference pioneered by Piaget to assess capacities for systematic organization of knowledge and logical inference in children. In our adaptation of the test, rats were trained on a set of four overlapping odor discrimination problems that could be encoded either separately or as a single representation of orderly relations among the odor stimuli. Normal rats learned the problems and demonstrated the relational memory organization through appropriate transitive inferences about items not presented together during training. By contrast, after disconnection of the hippocampus from either its cortical or subcortical pathway, rats succeeded in acquiring the separate discrimination problems but did not demonstrate transitive inference, indicating that they had failed to develop or could not inferentially express the orderly organization of the stimulus elements. These findings strongly support the view that the hippocampus mediates a general declarative memory capacity in animals, as it does in humans.

	Title	The Evolution of Political Intelligence: Simulation Results			Type	Journal Article
	Year	2002	Publication	British Journal of Political Science	Abbreviated Journal	Br. J. Polit. Sci.
	Volume	32	Issue		Pages	613-639
	Keywords
	Abstract	Several bodies of theory develop the idea that the intelligence of highly social animals – most interestingly, humans is significantly organized around the adaptive problems posed by their sociality. By this “political intelligence” hypothesis, sociality selects for, among other attributes, capacities for “manipulating” information others can gather about one's own future behaviour, and for “mindreading” such manipulations by others. Yet we have little theory about how diverse parameters of the games that social animals play select for political intelligence. We begin to address that with an evolutionary simulation in which agents choose between playing Prisoner's Dilemma and Hawk-Dove games on the basis of the information they can retrieve about each other given four broad information processing capacities. We show that political intelligence – operationally, the aggregate of those four capacities evolves to its highest levels when co-operative games are generally more attractive than conflictual ones, but when conflictual games are at least sometimes also attractive.
