Title Social Ecology of Horses Type Book Chapter
Year 2008 Publication (up) Ecology of Social Evolution Abbreviated Journal
Volume Issue Pages 195-206
Keywords
Abstract Horses (Equidae ) are believed to clearly demonstrate the links between ecology and social organization. Their social cognitive abilities enable them to succeed in many different environments, including those provided for them by humans, or the ones domestic horses encounter when escaping from their human care takers. Living in groups takes different shapes in equids. Their aggregation and group cohesion can be explained by Hamilton“s selfish herd theory. However, when an individual joins and to which group it joins appears to be an active individual decision depending on predation pressure, intra group harassment and resource availability. The latest research concerning the social knowledge horses display in eavesdropping experiments affirms the need for an extension of simple herd concepts in horses for a cognitive component. Horses obviously realize the social composition of their group and determine their own position in it. The horses exceedingly flexible social behavior demands for explanations about the cognitive mechanisms, which allow them to make individual decisions. ”Ecology conditions like those that favour the evolution of open behavioural programs sometimes also favour the evolution of the beginnings of consciousness, by favouring conscious choice. Or in other words, consciousness originates with the choice that are left open by open behavioural programs." Popper (1977)

Title Sex and Age Don't Matter, but Breed Type Does--Factors Influencing Eye Wrinkle Expression in Horses Type Journal Article
Year 2019 Publication (up) Frontiers in Veterinary Science Abbreviated Journal Front. Vet. Sci.
Volume 6 Issue Pages 154
Keywords
Abstract Identifying valid indicators to assess animals' emotional states is a critical objective of animal welfare science. In horses, eye wrinkles above the eyeball have been shown to be affected by pain and other emotional states. From other species we know that individual characteristics, e.g. age in humans, affect facial wrinkles, but it has not yet been investigated whether eye wrinkle expression in horses is systematically affected by such characteristics. Therefore, the aim of this study was to assess how age, sex, breed type, body condition and coat colour affect the expression and/or the assessment of eye wrinkles in horses. To this end, we adapted the eye wrinkle assessment scale from Hintze et al. (2016) and assessed eye wrinkle expression in pictures taken from the left and the right eye of 181 horses in a presumably neutral situation, using five outcome measures: a qualitative first impression reflecting how worried the horse is perceived by humans, the extent to which the brow is raised, the number of wrinkles, their markedness and the angle between a line through both corners of the eye and the topmost wrinkle. All measures could be assessed highly reliable with respect to intra- and inter-observer agreement. Breed type affected the width of the angle (F2, 114 = 8.20, p < 0.001), with thoroughbreds having the narrowest angle (M = 23.80, SD = 1.60), followed by warmbloods (M = 28.00, SD = 0.60), and coldbloods (M = 31.00, SD = 0.90). None of the other characteristics affected any of the outcome measures, and eye wrinkle expression did not differ between the left and the right eye area (all p-values > 0.05). In conclusion, horses' eye wrinkle expression and its assessment in neutral situations was not systematically affected by the investigated characteristics, except for 'breed type', which accounted for some variation in 'angle'; how much eye wrinkle expression is affected by emotion or perhaps mood needs further investigation and validation.

Title Social cognition and social learning in horses Type Conference Article
Year 2008 Publication (up) IESM 2008 Abbreviated Journal
Volume Issue Pages
Keywords
Abstract In comparison to other social animals it appears to be far more difficult to show social learning in horses, although the social background of the animals prompts the prediction that social learning should be verifiable. This demands for a thorough analysis of conditions, context and effects of social learning which might not be as obvious in horses than in other social animals. Moreover, the horse“s social cognition in general, i.e. the processing, encoding, storage, retrieval, and application of social information, needs to be examined. In previous studies we addressed the horse”s perception of it“s social environment. Our results indicate that domestic horses are not only capable of distinguishing between familiar and unfamiliar horses but also of recognizing the social status of familiar horses relative to their own. Furthermore, they extract information from observing interactions between a familiar horse and a human experimenter, and adjust their behaviour according to the observed horse”s reaction and relative dominance status when they are themselves later confronted with the experimenter in a similar situation. Additionally, we showed in pilot experiments that horses paid more attention to the gaze of dominant horses from their own social group than to that of unknown or subordinate horses. In another study we suggested that horses of both sexes are capable of determining the social affiliation, the sex and, for their own group members, the identity of individuals, by sniffing their faeces. Hence, social affiliation and dominance relationships seemed to have a major influence on the horses` motivation to pay attention to their conspecifics. In the future we will take another step towards linking the horse“s social cognitive capacities with its social ecology, social structure, and individuality. In the context of comparative cognition research on the socially complex primates, or on a range of carnivores such as corvids, canids or dolphins, horses are particularly interesting, because they are highly social, but do not rely on social hunting or cooperative raising of offspring. Also foraging is simple for horses, predator avoidance is demanding and this may be the main reason for the horse”s complex social lives and their choice of learning tactics. Hence, we will investigate the horse"s investigative behaviour towards neutral, fear-eliciting and food related novel objects. We propose that, as in other species, sociality and distinct personalities are key features for the understanding of cognitive capacities and the choice of learning strategies.
