Title Visual laterality in the domestic horse (Equus caballus) interacting with humans Type Journal Article
Year 2010 Publication Animal Cognition Abbreviated Journal Anim. Cogn.
Volume 13 Issue (up) Pages 229-238
Keywords Horse – Laterality – Eye preference – Emotion – Vision
Abstract Most horses have a side on which they are easier to handle and a direction they favour when working on a circle, and recent studies have suggested a correlation between emotion and visual laterality when horses observe inanimate objects. As such lateralisation could provide important clues regarding the horse’s cognitive processes, we investigated whether horses also show laterality in association with people. We gave horses the choice of entering a chute to left or right, with and without the passive, non-interactive presence of a person unknown to them. The left eye was preferred for scanning under both conditions, but significantly more so when a person was present. Traditionally, riders handle horses only from the left, so we repeated the experiment with horses specifically trained on both sides. Again, there was a consistent preference for left eye scanning in the presence of a person, whether known to the horses or not. We also examined horses interacting with a person, using both traditionally and bilaterally trained horses. Both groups showed left eye preference for viewing the person, regardless of training and test procedure. For those horses tested under both passive and interactive conditions, the left eye was preferred significantly more during interaction. We suggest that most horses prefer to use their left eye for assessment and evaluation, and that there is an emotional aspect to the choice which may be positive or negative, depending on the circumstances. We believe these results have important practical implications and that emotional laterality should be taken into account in training methods.

Title Third-party intervention Type Conference Article
Year 2012 Publication Proceedings of the 2. International Equine Science Meeting Abbreviated Journal Proc. 2. Int. Equine. Sci. Mtg
Volume Issue (up) Pages 73
Keywords
Abstract Third-party intervention is the interruption of a dyadic interaction by a third animal. We observed such interventions in affiliative interactions in free-ranging Esperia-ponies (Equus caballus). It is known that horses intervene in affiliative contexts especially when a preferred partner is involved, probably to protect their social bond to this preferred partner. To prove this hypothesis the present study investigated whether the preferred partner was targeted, i.e. challenged, or supported by the intervener or both randomly. Therefore we examined the social relationship between the intervener and both dyadic interacting individuals. We found that interveners usually supported individuals to which they have stronger social bonds than to other group mates, while they have no particular relationship to the targeted animals. This indicates that interveners in stable horse groups protect their social bonds to the supported animals by challenging their interaction partners. Of all observed horses only some mares showed intervention behaviour. Their social position, reflected by their position in the dominance hierarchy, social networks, and the spatial group structure were investigated. We found that interveners occupy no unique position, but they are involved in a high amount of affiliative interactions, high-ranking, and relatively aggressive. KW -

Title Heuristics and complex decisions in man and horses Type Conference Article
Year 2012 Publication Proceedings of the 2. International Equine Science Meeting Abbreviated Journal Proc. 2. Int. Equine. Sci. Mtg
Volume in press Issue (up) Pages
Keywords
Abstract Darwin’s claim of differences in mental abilities between man and other animals is a matter of degree rather than of kind and appears to apply nicely to a comparison of choice behaviour in humans and equine. Humans and horses make two kinds of decisions, fast reflexive decisions based on heuristics, and slower more considered decisions that require more complex cognitive processing. Heuristic use is adaptive in that decisions based on them are most often useful in helping an organism to survive while requiring little time and cognitive effort. There is considerable evidence that there is an innate basis to many heuristics in humans as well as horses. A case will be made that the investigation of heuristics specific to horses will lead to an understanding of equine behaviour that has not been possible using traditional learning theories alone. Traditional learning theories are restricted in explaining behaviour to appeals to reinforcement regimes or to the formation of associations between novel stimuli and stimuli that cause innate reflexes, but they are of no use when behaviour is controlled by stimuli that have never been reinforced or been systematically paired with other stimuli that cause reflexive responses. For example, a horse in a two-choice discrimination task may choose a familiar stimulus which has never been reinforced over a new stimulus added to the discrimination task, simply due to the use of an heuristic that usually works -- when in doubt, choose a more familiar object over an unfamiliar one. Conflict resolution strategies provide another good example of heuristic vs. slow decision making. In both humans and horses, conflict resolution strategies are used within, but not typically between social groups. Such groups can be defined as community of interest. Depending on the resource that has to be defended, groups may well be small identities, such as human families or horse harems, or large aggregations such as herds in horses, or religious groups or nations in humans. Fast and simple resolution is possible with stable social identities in simple environments, but more complicated and time consuming deliberative processes are required to resolve conflict over long-term resource acquisition, for decisions in complex conflicts situations and complex social settings.

Title Social feeding decisions in horses (Equus caballus) Type Conference Article
Year 2012 Publication Proceedings of the 2. International Equine Science Meeting Abbreviated Journal Proc. 2. Int. Equine. Sci. Mtg
Volume in press Issue (up) Pages
Keywords Feeding decision; Horse; Rank; Social behaviour
Abstract Like many other herbivores equids feed on rather evenly distributed resources. Especially in ruminants several studies have proved the influence of social organisations, rank, sex and the depletion of feeding sites on the feeding behaviour of individuals. However, it is not yet understood whether social aspects affect horses´ feeding decisions. Horses roam on vast habitats with constantly changing vegetation. In non-competitive situations domestic horses tend to return to the same feeding site until it is overgrazed. Whereas, for competition over limited food the social status of the individuals appears to be important. Curiosity about the influence of social rank and different social feeding conditions on the horses´ feeding decisions between two buckets, equally filled with high-quality surplus food, led us to create the test situation described here. The observer horses were alternately tested with a dominant and a subordinate demonstrator placed in one of three different positions. We conclude that domestic horses use cognitive strategic decision making in order to decide where to feed in a social feeding situation. When possible they tend to return to the same, continuously supplied feeding site and switch to an “avoidance tendency” when another horse is already feeding from it or in the presence of a dominant horse. Thus the position and the social rank of conspecifics affect the feeding strategy of horses.

Title Einflussfaktoren auf das Grooming-Verhalten bei wilden und verwilderten Pferden [Influencing factors on grooming behaviour in wild living horses] Type Book Chapter

Abstract Die soziale Fellpflege wurde bei Equiden intensiv erforscht. Es stellte sich heraus, dass diverse Faktoren das Grooming-Verhalten beeinflussen können. Neben saisonalen Gegebenheiten sind dies vor allem soziale Faktoren, wie das Alter und Geschlecht der Tiere, die Hierarchie und Gruppenzusammensetzung sowie die Verwandtschaftsverhältnisse der Tiere untereinander. Diese Faktoren können sowohl bei der Häufigkeit der sozialen Fellpflege, als auch bei der Wahl des Partners eine entscheidende Rolle spielen. Zudem konnte gezeigt werden, dass auch das Aggressivitätslevel in einer Gruppe Einfluss auf das soziale Verhalten und die soziale Fellpflege nehmen kann. Inwiefern zwei Individuen, die sich häufig groomen, auch bevorzugt beieinander stehen, konnte bislang noch nicht eindeutig gezeigt werden, da es hierzu diverse Studien mit konträren Ergebnisse gibt. Dieser Aspekt sollte zukünftig dringend untersucht werden, da die beiden Datensätze häufig gemeinsam verwendet werden, um soziale Bindungen zu berechnen, ohne dass bislang ein eindeutiger Zusammenhang zwischen ihnen ermittelt werden konnte.

[Summary

Social grooming has been investigated intensively in Equids during the last years and several factors are known to influence the grooming behaviour. Beside seasonal conditions these are especially social factors as age and sex, hierarchy and group composition as well as kinship. These factors can affect the grooming frequencies and influence the choice of the grooming partner. Moreover, it could be demonstrated that the groups’

aggression level can influence the social behaviour and the grooming intensity. If individuals which show an increased grooming frequency often stand in close proximity as well, has not been affirmed, as, so far, no distinct correlation has been demonstrated. This aspect has to be investigated urgently, as both data sets are often used in combination for calculating social bonds.]
