	Title	The social brain hypothesis and its implications for social evolution			Type	Journal Article
	Year	2009	Publication	Annals of Human Biology	Abbreviated Journal	Annals of Human Biology
	Volume	36	Issue	5	Pages	562-572
	Keywords
	Abstract	The social brain hypothesis was proposed as an explanation for the fact that primates have unusually large brains for body size compared to all other vertebrates: Primates evolved large brains to manage their unusually complex social systems. Although this proposal has been generalized to all vertebrate taxa as an explanation for brain evolution, recent analyses suggest that the social brain hypothesis takes a very different form in other mammals and birds than it does in anthropoid primates. In primates, there is a quantitative relationship between brain size and social group size (group size is a monotonic function of brain size), presumably because the cognitive demands of sociality place a constraint on the number of individuals that can be maintained in a coherent group. In other mammals and birds, the relationship is a qualitative one: Large brains are associated with categorical differences in mating system, with species that have pairbonded mating systems having the largest brains. It seems that anthropoid primates may have generalized the bonding processes that characterize monogamous pairbonds to other non-reproductive relationships (?friendships?), thereby giving rise to the quantitative relationship between group size and brain size that we find in this taxon. This raises issues about why bonded relationships are cognitively so demanding (and, indeed, raises questions about what a bonded relationship actually is), and when and why primates undertook this change in social style.

	Title	The social brain hypothesis			Type	Journal Article
	Year	1998	Publication	Evolutionary Anthropology: Issues, News, and Reviews	Abbreviated Journal	Evol. Anthropol.
	Volume	6	Issue	5	Pages	178-190
	Keywords	brain size – neocortex – social brain hypothesis – social skills – mind reading – primates
	Abstract	Conventional wisdom over the past 160 years in the cognitive and neurosciences has assumed that brains evolved to process factual information about the world. Most attention has therefore been focused on such features as pattern recognition, color vision, and speech perception. By extension, it was assumed that brains evolved to deal with essentially ecological problem-solving tasks. © 1998 Wiley-Liss, Inc.

	Title	The Role of Nonlinear Coupling in Human-Horse Interaction: a Preliminary Study			Type	Conference Article
	Year	2017	Publication	2016 38th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC)	Abbreviated Journal	EMBC
	Volume		Issue		Pages
	Keywords
	Abstract	This study focuses on the analysis of humanhorse dynamic interaction using cardiovascular information exclusively. Specifically, the Information Theoretic Learning (ITL) approach has been applied to a Human-Horse Interaction paradigm, therefore accounting for the nonlinear information of the heart-heart interplay between humans and horses. Heartbeat dynamics was gathered from humans and horses during three experimental conditions: absence of interaction, visual-olfactory interaction, and brooming. Cross Information Potential, Cross Correntropy, and Correntropy Coefficient were computed to quantitatively estimate nonlinear coupling in a group of eleven subjects and one horse. Results showed a statistical significant difference on all of the three interaction phases. Furthermore, a Support Vector Machine classifier recognized the three conditions with an accuracy of 90:9%. These preliminary and encouraging results suggest that ITL analysis provides viable metrics for the quantitative evaluation of human-horse interaction.

	Title	The role of an alpha animal in changing environmental conditions			Type	Journal Article
	Year	2014	Publication	Physiology & Behavior	Abbreviated Journal	Physiol. Behav.
	Volume	133	Issue		Pages	236-243
	Keywords	Alpha male; Horse; Equus ferus przewalskii; Bachelor group; Group structure
	Abstract	Abstract The maintenance and development of conservation areas by grazing of large herbivores, such as Przewalski's horses, is common practice. Several nature conservation areas house male bachelor groups of this species. When males are needed for breeding they are removed from the groups, often without considering group compositions and individual social positions. However, alpha animals are needed for ensuring group stability and decision making in potentially dangerous situations in several species. To investigate the role of the alpha male in a bachelor group, we observed the behaviour of five Przewalski's horse males during the enlargement of their enclosure. We analyzed the group's social structure and movement orders, as well as the animals' connectedness, activity budgets, and whether they moved with preferred group members and how factors such as social rank influenced the horses' behaviour. We also investigated the excretion of glucocorticoid metabolites (GCM) via faeces of the horses while exploring a new area as a parameter of glucocorticoid production. Our results show that the alpha male is important for a bachelor group in changing environmental conditions. The alpha male had the highest level of connectedness within the group. When exploring the new environment, its position in the group changed from previously being the last to being the first. Furthermore the whole group behaviour changed when exploring the new area. The stallions showed reduced resting behavior, increased feeding and did not stay close to each other. We found that the excretion of glucocorticoid metabolites of most horses rose only marginally during the first days on the new area while only the alpha male showed a significant increased amount of glucocorticoid production during the first day of the enclosure enlargement.

	Title	The Ridden Horse Pain Ethogram			Type	Journal Article
	Year	2022	Publication	Equine Veterinary Education	Abbreviated Journal	Equine Vet Educ
	Volume	34	Issue	7	Pages	372-380
	Keywords	horse; lameness; canter; behaviour; saddle-fit; rider skill
	Abstract	Summary The Ridden Horse Pain Ethogram (RHpE) comprises 24 behaviours, the majority of which are at least 10 times more likely to be seen in lame horses compared with non-lame horses. The observation of >=8/24 behaviours is likely to reflect the presence of musculoskeletal pain, although some lame horses score <8/24 behaviours. A marked reduction in RHpE scores after resolution of lameness using diagnostic anaesthesia proves a causal relationship between pain and RHpE scores. Horses should be assessed for approximately 10?min in walk, trot (including 10?m diameter circles), canter and transitions. The validity of the RHpE has been verified for use in horses which perform dressage-type movements, and which have been trained to work with the front of the head in a vertical position. It has not, as yet, been used in horses while jumping, racehorses, western performance or endurance horses. The RHpE provides a valuable tool for riders, trainers, veterinarians and other equine professionals to recognise the presence of musculoskeletal pain, even if overt lameness cannot be recognised. Riders with a higher skill-level may improve gait quality, but cannot obscure behavioural signs of pain, although specific behaviours may change. Tight saddle tree points, the rider sitting on the caudal third of the saddle and rider weight may influence RHpE scores. Accurate application of the RHpE requires training and practice. The RHpE is a powerful tool for the assessment of ridden horses and the identification of likely musculoskeletal pain. Such pain merits further investigation and treatment, to improve equine welfare and performance. The RHpE provides an additional means of evaluating the response to diagnostic anaesthesia. It provides a mechanism for client education and a diplomatic way of communicating with clients about equine discomfort related to saddle-fit, rider size, their position in the saddle and ability to ride in balance.

	Title	The responses of horses in a discrimination problem			Type	Journal Article
	Year	1937	Publication	Journal-of-Comparative-Psychology	Abbreviated Journal	J Comp Psychol
	Volume	23	Issue		Pages	305-333
	Keywords
	Abstract	62 horses were trained to obtain food from the one of three boxes which was covered with a black cloth. The position of the box varied from trial to trial in a random order. Learning was apparently in terms of vision, rather than smell. Many errors were due to the line of direction of the horse's movement as it entered the experimental situation. For all animals the learning curve dropped rapidly during the first few trials. There was slightly more rapid learning in younger horses than in older ones. No sex differences were apparent. Percherons made fewer errors than Belgians. Draft horses showed a slight superiority over military and farm horses. The statistical reliability of these differences is not reported. Good retention was evidenced after a period of several months. (PsycINFO Database Record (c) 2012 APA, all rights reserved)
