	Title	Dogs steal in the dark			Type	Journal Article
	Year	2013	Publication		Abbreviated Journal	Animal Cognition
	Volume	16	Issue	3	Pages	385-394
	Keywords	Domestic dog; Social cognition; Perspective taking; Competition
	Abstract	All current evidence of visual perspective taking in dogs can possibly be explained by dogs reacting to certain stimuli rather than understanding what others see. In the current study, we set up a situation in which contextual information and social cues are in conflict. A human always forbade the dog from taking a piece of food. The part of the room being illuminated was then varied, for example, either the area where the human was seated or the area where the food was located was lit. Results show that dogs steal significantly more food when it is dark compared to when it is light. While stealing forbidden food the dog’s behaviour also depends on the type of illumination in the room. Illumination around the food, but not the human, affected the dogs’ behaviour. This indicates that dogs do not take the sight of the human as a signal to avoid the food. It also cannot be explained by a low-level associative rule of avoiding illuminated food which dogs actually approach faster when they are in private. The current finding therefore raises the possibility that dogs take into account the human’s visual access to the food while making their decision to steal it.

	Title	Human Demonstration Does Not Facilitate the Performance of Horses (Equus caballus) in a Spatial Problem-Solving Task			Type	Journal Article
	Year	2018	Publication	Animal	Abbreviated Journal	Animal
	Volume	8	Issue	6	Pages	96
	Keywords	detour task; equids; social cognition; social learning; spatial cognition
	Abstract	Horses’ ability to adapt to new environments and to acquire new information plays an important role in handling and training. Social learning in particular would be very adaptive for horses as it enables them to flexibly adjust to new environments. In the context of horse handling, social learning from humans has been rarely investigated but could help to facilitate management practices. We assessed the impact of human demonstration on the spatial problem-solving abilities of horses during a detour task. In this task, a bucket with a food reward was placed behind a double-detour barrier and 16 horses were allocated to two test groups of 8 horses each. One group received a human demonstration of how to solve the spatial task while the other group received no demonstration. We found that horses did not solve the detour task more often or faster with human demonstration. However, both test groups improved rapidly over trials. Our results suggest that horses prefer to use individual rather than social information when solving a spatial problem-solving task

	Title	Positive interactions lead to lasting positive memories in horses, Equus caballus			Type	Journal Article
	Year	2010	Publication	Animal Behaviour	Abbreviated Journal	Anim. Behav.
	Volume	79	Issue	4	Pages	869-875
	Keywords	Equus caballus; horse; human–animal relationship; learning; memory; positive interaction; social cognition
	Abstract	Social relationships are important in social species. These relationships, based on repeated interactions, define each partner's expectations during the following encounters. The creation of a relationship implies high social cognitive abilities which require that each partner is able to associate the positive or negative content of an interaction with a specific partner and to recall this association. In this study, we tested the effects of repeated interactions on the memory kept by 23 young horses about humans, after 6 and 8 months of separation. The association of a reward with a learning task in an interactional context induced positive reactions towards humans during training. It also increased contact and interest, not only just after training, but also several months later, despite no further interaction with humans. In addition, this ‘positive memory’ of humans extended to novel persons. Overall, positive reinforcement enhanced learning and memorization of the task itself. These findings suggest remarkable social cognitive abilities that can be transposed from intraspecific to interspecific social contexts.

	Title	Social cognition			Type	Journal Article
	Year	2015	Publication	Animal Behaviour	Abbreviated Journal
	Volume	103	Issue		Pages	191-202
	Keywords	evolution; fitness; future research; personality; selective pressure; skill; social cognition
	Abstract	The social intelligence hypothesis argues that competition and cooperation among individuals have shaped the evolution of cognition in animals. What do we mean by social cognition? Here we suggest that the building blocks of social cognition are a suite of skills, ordered roughly according to the cognitive demands they place upon individuals. These skills allow an animal to recognize others by various means; to recognize and remember other animals' relationships; and, perhaps, to attribute mental states to them. Some skills are elementary and virtually ubiquitous in the animal kingdom; others are more limited in their taxonomic distribution. We treat these skills as the targets of selection, and assume that more complex levels of social cognition evolve only when simpler methods are inadequate. As a result, more complex levels of social cognition indicate greater selective pressures in the past. The presence of each skill can be tested directly through field observations and experiments. In addition, the same methods that have been used to compare social cognition across species can also be used to measure individual differences within species and to test the hypothesis that individual differences in social cognition are linked to differences in reproductive success.

	Title	Wolves outperform dogs in following human social cues			Type	Journal Article
	Year	2008	Publication	Animal Behaviour.	Abbreviated Journal	Anim. Behav.
	Volume	76	Issue	6	Pages	1767-1773
	Keywords	Canis familiaris; Canis lupus; dog; dog shelter; domestication; momentary distal point; object choice; social cognition; wolf
	Abstract	Domestic dogs, Canis familiaris, have been shown capable of finding hidden food by following pointing gestures made with different parts of the human body. However, previous studies have reported that hand-reared wolves, C. lupus, fail to locate hidden food in response to similar points in the absence of extensive training. The failure of wolves to perform this task has led to the proposal that the ability to understand others' intentions is a derived character in dogs, not present in the ancestral population (wolves). Here we show that wolves, given the right rearing environment and daily interaction with humans, can use momentary distal human pointing cues to find food without training, whereas dogs tested outdoors and dogs at an animal shelter do not follow the same human points. In line with past studies, pet dogs tested indoors were successful in following these points. We also show that the reported failure of wolves in some past studies may be due to differences in the testing environment. Our findings indicate that domestication is not a prerequisite for human-like social cognition in canids, and show the need for additional research on the role of rearing conditions and environmental factors in the development of higher-level cognitive abilities.

	Title	The use of human-given cues by domestic horses, Equus caballus, during an object choice task			Type	Journal Article
	Year	2010	Publication	Animal Behaviour.	Abbreviated Journal	Anim. Behav.
	Volume	79	Issue	6	Pages	1205-1209
	Keywords	domestication; Equus caballus; horse; interspecific communication; marker cue; pointing; social cognition
	Abstract	Selection pressures during domestication are thought to lead to an enhanced ability to use human-given cues. Horses fulfil a wide variety of roles for humans and have been domesticated for at least 5000 years but their ability to read human cues has not been widely studied. We tested the ability of 28 horses to attend to human-given cues in an object choice task. We included five different cues: distal sustained pointing, momentary tapping, marker placement, body orientation and gaze (head) alternation. Horses were able to use the pointing and marker placement cues spontaneously but not the tapping, body orientation and gaze alternation cues. The overall pattern of responding suggests that horses may use cues that provide stimulus enhancement at the time of choice and do not have an understanding of the communicative nature of the cues given. As such, their proficiency at this task appears to be inferior to that of domestic dogs, Canis lupus familiaris, but similar to that of domestic goats, Caprus hircus.

	Title	Cues to food location that domestic dogs (Canis familiaris) of different ages do and do not use			Type	Journal Article
	Year	2000	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	3	Issue	2	Pages	107-112
	Keywords	Dogs – Arctic wolves – Social cognition – Gaze following – Communication
	Abstract	Autoren B. Agnetta, B. Hare, M. Tomasello Zusammenfassung The results of three experiments are reported. In the main study, a human experimenter presented domestic dogs (Canis familiaris) with a variety of social cues intended to indicate the location of hidden food. The novel findings of this study were: (1) dogs were able to use successfully several totally novel cues in which they watched a human place a marker in front of the target location; (2) dogs were unable to use the marker by itself with no behavioral cues (suggesting that some form of human behavior directed to the target location was a necessary part of the cue); and (3) there were no significant developments in dogs' skills in these tasks across the age range 4 months to 4 years (arguing against the necessity of extensive learning experiences with humans). In a follow-up study, dogs did not follow human gaze into “empty space” outside of the simulated foraging context. Finally, in a small pilot study, two arctic wolves (Canis lupus) were unable to use human cues to locate hidden food. These results suggest the possibility that domestic dogs have evolved an adaptive specialization for using human-produced directional cues in a goal-directed (especially foraging) context. Exactly how they understand these cues is still an open question. Schlüsselwörter Key words Dogs – Arctic wolves – Social cognition – Gaze following – Communication

	Title	Chimpanzees do not take into account what others can hear in a competitive situation			Type	Journal Article
	Year	2008	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	11	Issue	1	Pages	1435-9448
	Keywords	Social cognition – Food competition – Perspective taking
	Abstract	Chimpanzees (Pan troglodytes) know what others can and cannot see in a competitive situation. Does this reflect a general understanding the perceptions of others` In a study by Hare et al. (2000) pairs of chimpanzees competed over two pieces of food. Subordinate individuals preferred to approach food that was behind a barrier that the dominant could not see, suggesting that chimpanzees can take the visual perspective of others. We extended this paradigm to the auditory modality to investigate whether chimpanzees are sensitive to whether a competitor can hear food rewards being hidden. Results suggested that the chimpanzees did not take what the competitor had heard into account, despite being able to locate the hiding place themselves by the noise.

	Title	I know you are not looking at me: capuchin monkeys` ? (Cebus apella) sensitivity to human attentional states			Type	Journal Article
	Year	2007	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	10	Issue	2	Pages	141-148
	Keywords	Capuchin monkeys – Attentional state – Gaze – Social cognition
	Abstract	Abstract  The present study asked whether capuchin monkeys recognize human attentional states. The monkeys requested food from the experimenter by extending an arm (pointing) toward the baited one of two transparent cups. On regular trials the experimenter gave the food immediately to the monkeys upon pointing but on randomly inserted test trials she ignored the pointing for 5 s during which she displayed different attentional states. The monkeys looked at the experimenter's face longer when she looked at the monkeys than when she looked at the ceiling in Experiment 1, and longer when she oriented her head midway between the two cups with eyes open than when she did so with eyes closed in Experiment 2. However, the monkeys showed no differential pointing in these conditions. These results suggest that capuchins are sensitive to eye direction but this sensitivity does not lead to differential pointing trained in laboratory experiments. Furthermore, to our knowledge, this is the first firm behavioral evidence that non-human primates attend to the subtle states of eyes in a food requesting task.

	Title	*Horse sense: social status of horses (Equus caballus) affects their likelihood of copying other horses` behavior*			Type	Journal Article
	Year	2008	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	11	Issue	3	Pages	431-439
	Keywords	copying, horse, social cognition, sociality
	Abstract	Animals that live in stable social groups need to gather information on their own relative position in the group`s social hierarchy, either by directly threatening or challenging others, or in a less costly manner, by observing interactions among others. Such indirect inference of dominance relationships has previously been reported from primates, rats, and birds and fish. Here, we show that domestic horses, Equus caballus, are similarly capable of social cognition. Taking advantage of a specific “following behavior” that horses show towards humans in a riding arena, we investigated whether bystander horses adjust their response to an experimenter according to the observed interaction and their own dominance relationship with the horse whose reaction to the experimenter they had observed before. Horses copied the following behavior towards an experimenter after watching a dominant horse following, but did not follow after observing a subordinate horse or a horse from another social group doing so. The following behavior which horses show towards an experimenter therefore appears to be affected by the demonstrator`s behavior and social status relative to the observer.
