	Title	“Constructive” enumeration by chimpanzees (Pan troglodytes) on a computerized task			Type	Journal Article
	Year	2001	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	4	Issue	2	Pages	81-89
	Keywords
	Abstract	Two chimpanzees used a joystick to collect dots, one at a time, on a computer monitor (see video-clip in the electronic supplementary material), and then ended a trial when the number of dots collected was equal to the Arabic numeral presented for the trial. Both chimpanzees performed substantially and reliably above chance in collecting a quantity of dots equal to the target numeral, one chimpanzee for the numerals 1-7, and the second chimpanzee for the numerals 1-6. Errors that were made were seldom discrepant from the target by more than one dot quantity, and the perceptual process subitization was ruled out as an explanation for the performance. Additionally, analyses of trial duration data indicated that the chimpanzees were responding based on the numerosity of the constructed set rather than on the basis of temporal cues. The chimpanzees' decreasing performance with successively larger target numerals, however, appeared to be based on a continuous representation of magnitude rather than a discrete representation of number. Therefore, chimpanzee counting in this type of experimental task may be a process that represents magnitudes with scalar variability in that the memory for magnitudes associated with each numeral is imperfect and the variability of responses increases as a function of the numeral's value.

	Title	“Insightful” string-pulling in Grey parrots (Psittacus erithacus) is affected by vocal competence			Type	Journal Article
	Year	2004	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	7	Issue	4	Pages	263-266
	Keywords	Animals; Association Learning; Discrimination Learning; Humans; Male; Parrots; Problem Solving; Verbal Behavior; Verbal Learning; *Vocalization, Animal
	Abstract	Four Grey parrots (Psittacus erithacus) were tested on their ability to obtain an item suspended from a string such that mutiple, repeated, coordinated beak-foot actions were required for success (e.g., Heinrich 1995). Those birds with little training in referential English requests (e.g. “I want X”) succeeded, whereas birds who could request the suspended item failed to obtain the object but engaged in repeated requesting.

	Title	“Learning to speak horse”: The culture of “natural horsemanship”			Type	Journal Article
	Year	2007	Publication	Society and Animals	Abbreviated Journal
	Volume	15	Issue	3	Pages	217-239
	Keywords	natural horsemanship – riding technologies – communication – social change
	Abstract	This paper examines the rise of what is popularly called “natural horsemanship” (NH), as a definitive cultural change within the horse industry. Practitioners are often evangelical about their methods, portraying NH as a radical departure from traditional methods. In doing so, they create a clear demarcation from the practices and beliefs of the conventional horse-world. Only NH, advocates argue, properly understands the horse. Dissenters, however, contest the benefits to horses as well as the reliance in NH on disputed concepts of the natural. Advocates, furthermore, sought to rename technologies associated with riding while simultaneously condemning technologies used in conventional training (such as whips). These contested differences create boundaries and enact social inclusion and exclusion, which the paper explores. For horses, the impact of NH is ambiguous: Depending on practitioners, effects could be good or bad. However, for the people involved, NH presents a radical change-which they see as offering markedly better ways of relating to horses and a more inclusive social milieu.

	Title	'Mindreading' Mammals? Attribution of Belief Tasks with Dolphins			Type	Journal Article
	Year	2001	Publication	Animal Welfare	Abbreviated Journal	Anim Welfare
	Volume	10	Issue		Pages	119-127
	Keywords
	Abstract	'Mindreading' or theory of mind (ToM) refers to the capacity to attribute mental states to others. This ability is regarded as a critical component of what has, to date, exclusively characterized the advanced social cognition displayed by humans. The false belief task is a key test for ToM in different animal species. On a standard non-verbal false belief task, humans pass from age 4, whereas non-human primates consistently fail. Neuroanatomical and behavioural evidence for dolphins, however, indicates that they are capable of passing ToM tasks. The current paper represents a synthesis of the relevant dolphin research on neocortical evolution and non-invasive behavioural tests of precursors for ToM and the attribution of beliefs. The success of dolphins on attribution of belief tasks, in the absence of learning or cueing, indicates that they are capable of 'mindreading'. What are the implications of animal 'mindreading'? ToM tasks probe for reflexive consciousness and, by this criterion, dolphins may display reflexive consciousness. The implication of this conclusion is that future behavioural studies of social cognition will have considerable ethical and legal implications for animal welfare.

	Title	A brief note on some possible factors involved in the reactions of horses to humans			Type	Journal Article
	Year	2002	Publication	Applied Animal Behaviour Science	Abbreviated Journal	Appl. Anim. Behav. Sci.
	Volume	76	Issue	4	Pages	339-344
	Keywords	Horses; Aggressiveness; Behavioural reactions; Human-animal relationship
	Abstract	In order to investigate relationships of adult horses to humans, we developed a simple evaluation test and scores based on observations. The first reactions of 224 adult horses to the presence of an experimenter were observed and scored. All these horses belonged to the same riding school, had the same general housing conditions and were all geldings. The evaluation was based on the horse's posture. Individual differences that could be related to some extent to the breed but also to human factors emerged clearly. French saddlebreds showed more often friendly behaviour than Angloarabs, whereas thoroughbreds were more indifferent. Clear variations occurred between groups of horses that depended on different caretakers. In this school, one caretaker is responsible for the whole daily management of a group of horses and is probably a very important factor in their well-being. The effects of this daily relation to a human seemed to be involved in the reactions to a strange person. Further studies are required to investigate what, in practice, may be determinant.

	Title	A Capuchin monkey (Cebus apella) recognizes when people do and do not know the location of food			Type	Journal Article
	Year	2003	Publication	Animal Cognition	Abbreviated Journal	Anim. Cogn.
	Volume	6	Issue	4	Pages	283-291
	Keywords	Adaptation, Psychological; Animals; Cebus/psychology; Communication; Concept Formation; Cues; Discrimination Learning; Feeding Behavior/*psychology; Female; Intention; Male; Social Identification; Transfer (Psychology)
	Abstract	In a previous study, Kuroshima and colleagues demonstrated that capuchin monkeys (Cebus apella) learned to discriminate between a “knower” who inspected a box for food, and a “guesser” who did not. The aim of the present study was to specify whether the subjects learned a simple conditional discrimination or a causal relationship that seeing leads to knowing. In experiment 1, we introduced five types of novel containers to two subjects. Each container was of different shape and color. The subjects gradually learned to reach toward the container the knower suggested. In experiment 2, we diversified the behavior of the knower and the guesser. In experiment 3, in order to eliminate the possibility of discrimination based on differences in the magnitude and the complexity of two trainers, we equated their behaviors. One subject adapted to the novel behaviors of the knower and the guesser, successfully discriminating the two trainers. Thus this monkey clearly learned to use the inspecting action of the knower and the non-inspecting action of the guesser as a discriminative cue to recognize the baited container. This result suggests that one capuchin monkey learned to recognize the relationship between seeing and knowing.

	Title	A case of male infanticide in Equus przewalskii			Type	Journal Article
	Year	1988	Publication	Applied Animal Behaviour Science	Abbreviated Journal	Appl. Anim. Behav. Sci.
	Volume	21	Issue	1-2	Pages	187-190
	Keywords
	Abstract	Following the introduction of a new stallion to a band of E. przewalskii mares two births, both of male foals, resulted in foal death due to injuries sustained in the first day of life. Neither foal was sired by the new herd stallion. The second foal death was the results of an observed attack on the newborn male and is described here. Subsequently births in the same enclosure and, in one instance, to the same mare whose previous foal was killed, were of foals sired by the new stallion and were uneventful, with 3 male foals surviving to date.

	Title	A comparative analysis of animals' understanding of the human pointing gesture			Type	Journal Article
	Year	2006	Publication	Animal cognition	Abbreviated Journal	Anim. Cogn.
	Volume	9	Issue	2	Pages	81-93
	Keywords	Animal Communication; Animals; Behavior, Animal; Child; Child, Preschool; Dogs; Fixation, Ocular; Gestures; Hand; Humans; Nonverbal Communication; Pinnipedia; Primates; Problem Solving; *Recognition (Psychology); Species Specificity
	Abstract	We review studies demonstrating the ability of some animals to understand the human pointing gesture. We present a 3-step analysis of the topic. (1) We compare and evaluate current experimental methods (2) We compare available experimental results on performance of different species and investigate the interaction of species differences and other independent variables (3) We evaluate how our present understanding of pointing comprehension answers questions about function, evolution and mechanisms. Recently, a number of different hypotheses have been put forward to account for the presence of this ability in some species and for the lack of such comprehension in others. In our view, there is no convincing evidence for the assumption that the competitive lifestyles of apes would inhibit the utilization of this human gesture. Similarly, domestication as a special evolutionary factor in the case of some species falls short in explaining high levels of pointing comprehension in some non-domestic species. We also disagree with the simplistic view of describing the phenomenon as a simple form of conditioning. We suggest that a more systematic comparative research is needed to understand the emerging communicative representational abilities in animals that provide the background for comprehending the human pointing gesture.

	Title	A comparison of bonobo and chimpanzee tool use: evidence for a female bias in the Pan lineage			Type	Journal Article
	Year	2010	Publication	Animal Behaviour	Abbreviated Journal	Anim. Behav.
	Volume	80	Issue	6	Pages	1023-1033
	Keywords	culture; great ape; neoteny; Pan; primate evolution; sex difference; tool use
	Abstract	Chimpanzees, Pan troglodytes, are the most sophisticated tool-users among all nonhuman primates. From an evolutionary perspective, it is therefore puzzling that the tool use behaviour of their closest living primate relative, the bonobo, Pan paniscus, has been described as particularly poor. However, only a small number of bonobo groups have been studied in the wild and only over comparably short periods. Here, we show that captive bonobos and chimpanzees are equally diverse tool-users in most contexts. Our observations illustrate that tool use in bonobos can be highly complex and no different from what has been described for chimpanzees. The only major difference in the chimpanzee and bonobo data was that bonobos of all age–sex classes used tools in a play context, a possible manifestation of their neotenous nature. We also found that female bonobos displayed a larger range of tool use behaviours than males, a pattern previously described for chimpanzees but not for other great apes. Our results are consistent with the hypothesis that the female-biased tool use evolved prior to the split between bonobos and chimpanzees.
