    Third-party interventions keep social partners from exchanging affiliative interactions with others

    Third-party interventions are defined as the interruption of dyadic interactions by third animals through direct physical contact, interposing or threats. Previous studies focused on the analysis of interventions against agonistic encounters. However, there have been no evaluations of interventions against affiliative behaviours, particularly in relation to the intervening animal’s social relationships and its social and spatial position. Horses, Equus caballus, are an interesting model species, as interventions against affiliative interactions occur more frequently than against agonistic interactions. In this study, 64 feral horses displayed 67 interventions in affiliative interactions and eight interventions in agonistic interactions within the observation period. We analysed the interventions in affiliative encounters, and found that it was mainly higher-ranking females that intervened in the affiliative interactions of group mates in the stable horse harems. The intervening animals took an active part in affiliative and agonistic encounters within the group, but did not occupy particular social roles or spatial positions. They intervened in affiliative interactions in which group mates with which they had social bonds interacted with other members of the group. They targeted the nonbonded animal and approached the one with which they were socially bonded. We suggest some species use third-party interventions in affiliative interactions to prevent competition for preferred social interaction partners from escalating into more costly agonistic encounters

    Sensory laterality in affiliative interactions in domestic horses and ponies (Equus caballus)

    Many studies have been carried out into both motor and sensory laterality of horses in agonistic and stressful situations. Here we examine sensory laterality in affiliative interactions within four groups of domestic horses and ponies (N = 31), living in stable social groups, housed at a single complex close to Vienna, Austria, and demonstrate for the first time a significant population preference for the left side in affiliative approaches and interactions. No effects were observed for gender, rank, sociability, phenotype, group, or age. Our results suggest that right hemisphere specialization in horses is not limited to the processing of stressful or agonistic situations, but rather appears to be the norm for processing in all social interactions, as has been demonstrated in other species including chicks and a range of vertebrates. In domestic horses, hemispheric specialization for sensory input appears not to be based on a designation of positive versus negative, but more on the perceived need to respond quickly and appropriately in any given situation.Publisher PDFPeer reviewe

    „Erfasst“ das Pferd die menschliche Psyche?

    Dieses Kapitel beschäftigt sich mit Hinweisen auf Fähigkeiten der Pferde, die menschliche Psyche wahrzunehmen und zu reflektieren. Ganz bewusst habe ich diesen Satz vorsichtig formuliert, da die Wissenschaft auf diesem Gebiet noch in den Kinderschuhen steckt. Allerdings steigt die Zahl der Wissenschaftler, welche sich auf das Gebiet der Erforschung tierischer Emotionen wagen und auch beim Pferd gibt es schon einige Ergebnisse, welche recht interessante Rückschlüsse zulassen. Im folgenden Kapitel möchte ich deswegen ähnlich wie bei einer Indizien-Recherche vorgehen und mit der Darstellung des Themengebietes beginnen, dann relevante, wissenschaftliche Berichte zur Emotionalität des Pferdes vorstellen und in einer abschließenden Bewertung die Bedeutung der bereits durchgeführten Studien diskutieren

    Evidence for Right-Sided Horses Being More Optimistic than Left-Sided Horses

    An individual’s positive or negative perspective when judging an ambiguous stimulus (cognitive bias) can be helpful when assessing animal welfare. Emotionality, as expressed in approach or withdrawal behaviour, is linked to brain asymmetry. The predisposition to process information in the left or right brain hemisphere is displayed in motor laterality. The quality of the information being processed is indicated by the sensory laterality. Consequently, it would be quicker and more repeatable to use motor or sensory laterality to evaluate cognitive bias than to perform the conventional judgment bias test. Therefore, the relationship between cognitive bias and motor or sensory laterality was tested. The horses (n = 17) were trained in a discrimination task involving a box that was placed in either a “positive„ or “negative„ location. To test for cognitive bias, the box was then placed in the middle, between the trained positive and negative location, in an ambiguous location, and the latency to approach the box was evaluated. Results indicated that horses that were more likely to use the right forelimb when moving off from a standing position were more likely to approach the ambiguous box with a shorter latency (generalized linear mixed model, p < 0.01), and therefore displayed a positive cognitive bias (optimistic)

    Viele Reiter fühlen sich nicht fit fürs Pferd. Fehlende Beweglichkeit und Kraft können eine Ursache für einen Trainingsstillstand sein.Wie sieben jungen Reiterinnen die regelmäßige Praxis von Yoga zu einem besseren Gefühl im Sattel verhelfen konnte und welche weiteren positiven Effekte das Training auf Körper und Geist hat, zeigt diese Studie im Rahmen einer Bachelorarbeit an der HfWU Nürtingen

    Laterality in Horse Training

    For centuries, a goal of training in many equestrian disciplines has been to straighten the horse, which is considered a key element in achieving its responsiveness and suppleness. However, laterality is a naturally occurring phenomenon in horses and encompasses body asymmetry, motor laterality and sensory laterality. Furthermore, forcibly counterbalancing motor laterality has been considered a cause of psychological imbalance in humans. Perhaps asymmetry and laterality should rather be accepted, with a focus on training psychological and physical balance, coordination and equal strength on both sides instead of enforcing “straightness”. To explore this, we conducted a review of the literature on the function and causes of motor and sensory laterality in horses, especially in horses when trained on the ground or under a rider. The literature reveals that body asymmetry is innate but does not prevent the horse from performing at a high level under a rider. Motor laterality is equally distributed in feral horses, while in domestic horses, age, breed, training and carrying a rider may cause left leg preferences. Most horses initially observe novel persons and potentially threatening objects or situations with their left sensory organs. Pronounced preferences for the use of left sensory organs or limbs indicate that the horse is experiencing increased emotionality or stress, and long-term insufficiencies in welfare, housing or training may result in left shifts in motor and sensory laterality and pessimistic mentalities. Therefore, increasing laterality can be regarded as an indicator for insufficiencies in housing, handling and training. We propose that laterality be recognized as a welfare indicator and that straightening the horse should be achieved by conducting training focused on balance, coordination and equal strength on both sides
