Social behavior in horses encompasses the interactions and relationships that occur between individual horses within a group setting. These behaviors are influenced by factors such as hierarchy, communication, and social bonding, which are integral to the social structure of equine groups. Horses engage in various social behaviors, including grooming, play, and aggression, which facilitate group cohesion and stability. Understanding social behavior in horses provides insights into their welfare, management, and training. This page compiles peer-reviewed research studies and scholarly articles that explore the patterns, functions, and implications of social behavior in horses.
In social animals, recognizing conspecifics and distinguishing them from other animal species is certainly important. We hypothesize, as demonstrated in other species of ungulates, that horses are able to discriminate between the faces of conspecifics and the faces of other domestic species (cattle, sheep, donkeys and pigs). Our hypothesis was tested by studying inter-and intra-specific visual discrimination abilities in horses through a two-way instrumental conditioning task (discrimination and reversal learning), using two-dimensional images of faces as discriminative stimuli and food as a p...
Narciso MHPM, da Luz MPF, Maia CM, Filho JNPP.Little is known about the dominance and leadership behaviors in the social structure of mules (Equus caballus × Equus asinus). Based on the frequency of threat and aggressive behaviors, we compared the social structure, dominance, and leadership of independent groups of mules and horses (n = 11 per group), and filmed the frequency of these behaviors over a period of four days. In both groups, aggressions were uncommon and, when based on threats, the social structure was linear and consistent with males ranking higher in dominance. When compared to horses, mules exhibited some agonistic so...
Maeda T, Ochi S, Ringhofer M, Sosa S, Sueur C, Hirata S, Yamamoto S.The study of non-human multilevel societies can give us insights into how group-level relationships function and are maintained in a social system, but their mechanisms are still poorly understood. The aim of this study was to apply spatial association data obtained from drones to verify the presence of a multilevel structure in a feral horse society. We took aerial photos of individuals that appeared in pre-fixed areas and collected positional data. The threshold distance of the association was defined based on the distribution pattern of the inter-individual distance. The association rates o...
Janczarek I, Wiśniewska A, Chruszczewski MH, Tkaczyk E, Górecka-Bruzda A.We tested the hypothesis that social defensive responses to the vocalisation of a predator still exist in horses. The recordings of a grey wolf, an Arabian leopard and a golden jackal were played to 20 Konik polski and Arabian mares. Durations of grazing, standing still, standing alert and the number of steps in walk and trot/canter were measured. In one-minute scans, the distances of the focal horse from the reference horse (DIST-RH) and from the nearest loudspeaker (DIST-LS) were approximated. The vocalisation of a leopard aroused the Arabians more than the Koniks (less grazing, stand-still ...
Giles SL, Harris P, Rands SA, Nicol CJ.Individual animals experience different costs and benefits associated with group living, which may impact on their foraging efficiency in ways not yet well specified. This study investigated associations between social dominance, body condition and interruptions to foraging behaviour in a cross-sectional study of 116 domestic horses and ponies, kept in 20 discrete herds. Social dominance was measured for each individual alongside observations of winter foraging behaviour. During bouts of foraging, the duration, frequency and category (vigilance, movement, social displacements given and receive...
Regan CE, Medill SA, Poissant J, McLoughlin PD.The adult sex ratio (ASR) is important within ecology due to its predicted effects on behaviour, demography and evolution, but research examining the causes and consequences of ASR bias have lagged behind the studies of sex ratios at earlier life stages. Although ungulate ASR is relatively well-studied, exceptions to the usual female-biased ASR challenge our understanding of the underlying drivers of biased ASR and provide an opportunity to better understand its consequences. Some feral ungulate populations, including multiple horse populations, exhibit unusually male-biased ASR. For example, ...
Hildebrandt F, Krieter J, Büttner K, Salau J, Czycholl I.Group housing is claimed to possibly provide horses with a species-appropriate movement possibility, and hence, better welfare. Thus, this study analyzed the daily walked distances of 51 horses held in one group in a "HIT Active Stable" (Hinrichs Innovation + Technik) in Northern Germany by using global positioning system (GPS) technology during a 7 ½-month time span. The daily walking distances of the whole group, as well as newcomers, were investigated. The horses traveled an average of 8.43 km/day. Linear mixed models were applied. The observation day had a significant effect on the dail...
Törmälehto E, Korkiamäki R.Previous research has shown features of an attachment bond to be fulfilled in, for instance, human-dog dyads; however, there is a considerable lack of research on the potential attachment in human-horse relationships. Employing Bowlby's criteria of an attachment bond and Pierce's model of therapeutically powerful activity, this article studies whether short-term exposure to horses brings about elements of emerging attachment for adolescents and if this interaction holds potential in creating a favorable early-stage setting for professional care. It draws from group discussions carried out with...
Shimada M, Suzuki N.Although herd size, structure, stability, and social rank among Misaki feral horses have been reported, no studies have been conducted on the affiliative relationships and interactions among members in a Misaki horse herd. The validity of three hypotheses regarding the function of social grooming, the affiliative relationship strengthening hypothesis, the worsened relationship restoring hypothesis, and the grooming parasite removal hypothesis, were tested in a Misaki feral horse () herd in Cape Toi, Japan. All the nine horses in the "6m" herd were investigated in terms of kinship, grooming, ag...
Animal-assisted interventions are considered an innovative rehabilitation approach to improve social, emotional, and physical domains in several diseases. Among such treatments, the equine-assisted activities and therapies have been developed to support the conventional approaches. There is growing evidence on the beneficial effects of hippotherapy, whereas few data are available regarding donkey therapy. Herein, we compare such treatments, hypothesizing their best application field to reach the proper therapeutic outcomes.
Schwarzmüller-Erber G, Stummer H, Maier M, Kundi M.Connectedness to nature and nature contact can provide many benefits to humans, like stress reduction, recovery from illness, and increased positive emotions. Likewise, recreational horseback riding is a widespread sports activity with the potential to enhance physical and psychological health. Yet, the influence of connectedness to nature on the wellbeing of older aged recreational horseback riders has not been investigated so far. The aim of the present study therefore was to explore the relationship between nature relatedness and physical, psychological and social wellbeing and happiness. T...
Kalmbach D, Wood W, Peters BC.This paper reports on the qualitative phase of a mixed methods study of occupational therapy in an equine environment for children with autism spectrum disorder (ASD). The study's quantitative phase found that this intervention improved the occupational performance, social motivation, social communication, and self-regulation of some children with ASD. The study's qualitative phase, reported herein, subsequently aimed to describe parental perspectives on children's experiences of the intervention and its influences on everyday life. Using a qualitative descriptive research approach, five paren...
De Klerk JN, Quan M, Grewar JD.In the Cape Flats townships, Cape Town, South Africa, there are more than 250 working cart horses. They serve the community with scrap metal and garden refuse removal, human transport and the selling of goods. A questionnaire was undertaken to understand the social and economic impacts of a horse and cart in the Cape Flats on individual owners and/or drivers, their households and the community. A mixture of classical quantitative questions combined with qualitative participatory technique questions were used. A total of 100 participants took part in the questionnaire, who cart with 163 horses ...
Maglieri V, Bigozzi F, Riccobono MG, Palagi E.Social play is a window on cognitive and communicative abilities of species. Inter-specific play, in particular, is a fertile venue to explore the capacity to correctly perceive and interpret signals emitted by partners. Up to now, most studies have focussed on dog-human play due to the important implications such studies have in understanding the peculiar relationship we establish with our pets. Here, we focussed on social play between dogs and horses. By using a set of specific keywords (dog, horse, play, friend) we selected 20 videos of dog-horse social play (with each session lasting >3...
Gérard C, Valenchon M, Poulin N, Petit O.In collective movements, some individuals are more effective and attractive leaders than others. Parameters such as social network, personality, and physiologic needs failed to explain why group members follow one leader more than another. In this study in the domestic horse, we propose to focus on the leader's attitude and its impact to the followers' recruitment during two conditions: spontaneous group departures or experimentally induced departures. We postulate that the expressiveness of the leader could enhance its attractiveness and thus produce a successful followership. We found that a...
Lovrić R, Farčić N, Mikšić Š, Gvozdanović Debeljak A.Therapeutic horseback riding (THR) has a positive effect on the physical, cognitive, and psychosocial functioning of children with disabilities. Parents' reports of the effects of THR on their children support professionals in individualizing the THR program. With this qualitative study, we aimed to explore parents' perceptions of changes in the basic life needs of their children with disabilities after six months of THR lessons and to survey parents' explanations for the causes of these changes. The study involved parents of 13 children with disabilities who were enrolled in a six-month THR p...
Rørvang MV, Nielsen TB, Christensen JW.Animals can acquire new behavior through both individual and social learning. Several studies have investigated horses' ability to utilize inter-species (human demonstrator) social learning with conflicting results. In this study, we repeat a previous study, which found that horses had the ability to learn from observing humans performing an instrumental task, but we include a control for stimulus enhancement. One human demonstrator and thirty horses were included, and the horses were randomly assigned to one of three treatments: (A) full human demonstration, (B) partial human demonstration, a...
Gilboa Y, Helmer A. Attention deficit/hyperactivity disorder (ADHD), characterized by inattention, hyperactivity, and impulsivity, is currently one of the most common diagnoses given to children. Children with ADHD have a unique cognitive profile that involves difficulties in executive functions (EFs) and in the self-management system of the brain, and are at higher risk for educational failure, social and emotional difficulties, and high risk behavior. The purpose of this study was to examine the effectiveness of self-management intervention for attention and executive functions using equine-assisted occupatio...
Pluháček J, Tučková V, Šárová R, King SRB.Overmarking remains an unstudied topic in juvenile mammals. We have previously documented a very high rate of overmarking by foals in four captive African equid species: mountain zebra (Equus zebra), plains zebra (Equus quagga), Grévy's zebra (Equus grevyi), and African wild ass (Equus africanus). African equids vary interspecifically in their social organisation. Since differences in social organisation affect many mammalian behaviours, in this study we investigated interspecific differences in overmarking behaviour of foals, analysing only cases where elimination of any other individual was...
Coffin J.Background: Recent statistics have painted a grim picture for Australia's Aboriginal youth, with reports of higher levels of almost every health indicator, including depression, sexual and emotional abuse, unemployment, and incarceration. Traditional western based therapies have proven to have limited effectiveness in engaging this group as they can often be culturally inappropriate. International studies have provided promising results using equine assisted learning, with a sound methodological basis underpinned by Indigenous ways of being and doing. In Australia Aboriginal people have strong...
Bernauer K, Kollross H, Schuetz A, Farmer K, Krueger K.A previous study demonstrated that horses can learn socially from observing humans, but could not draw any conclusions about the social learning mechanisms. Here we develop this by showing horses four different human action sequences as demonstrations of how to press a button to open a feed box. We tested 68 horses aged between 3 and 12 years. 63 horses passed the habituation phase and were assigned either to the group Hand Demo (N = 13) for which a kneeling person used a hand to press the button, Head Demo (N = 13) for which a kneeling person used the head, Mixed Demo (N = 12) fo...
van der Steen S, Heineman MMP, Ernst MJA.Multiple authors have called for strong empirical evaluations to strengthen the foundation of Animal-Assisted Interventions. Carefully choosing the outcome measures of these studies is important, as choosing the wrong outcomes may lead to a failure to detect effects. The current study therefore compares and contrasts the use of several outcome measures, to assess the effect of an equine-assisted intervention for a child with Autism Spectrum Disorder: (1) a semi-structured interview with both parents, specifically designed for children with cognitive disabilities, (2) a general screening instru...
Kinney AR, Eakman AM, Lassell R, Wood W.Evidence-based treatments for service-related health conditions such as posttraumatic stress disorder (PTSD), depression, and traumatic brain injury (TBI) are not effective for all veterans. Equine-assisted interventions are emerging as an additional treatment modality, but little is known regarding the safe and effective delivery of these interventions. This study aimed to describe the following features of the body of literature concerning equine-assisted interventions among veterans: 1) veterans who have participated in equine-assisted interventions; 2) specific characteristics of equine-as...
Henriksson J, Sauveroche M, Roth LSV.Due to our long history of living in close association with horses, these animals are suggested to have enhanced skills in understanding and communicating with humans. Today, horses have become important to humans for sport and leisure and their understanding of human behaviour and their human-directed behaviour are therefore of great importance. In this study, we investigated 22 horses in a human contact-seeking experiment where they were presented with an unsolvable problem and a detour experiment with a human demonstrator. The unsolvable problem consisted of pieces of carrot in a closed buc...
Grandin T.I was born in 1947 and had autism with speech delay until age four. I am now a college professor of animal science. Horse activities enabled me to make friends through a shared interest in horses. This paper describes the benefits that I experienced from working with horses and my friendships and work skills. A close friendship developed with another student through both riding and horse craft projects. Keeping employment is a serious problem for many people with Autism Spectrum Disorder (ASD). The responsibility of caring for horses and cleaning stalls every day taught me good work skills. My...
Martin RA, Taylor WJ, Surgenor LJ, Graham FP, Levack WMM, Blampied NM. Therapeutic horse riding aims to improve the health of children and young people experiencing disability; however, its benefits across a range of health domains, particularly the impact on participation outcomes, are not well known. This research evaluated to what extent there was a change in riders balance, functional performance, social responsiveness, quality of life and participation outcomes as a result of therapeutic horse riding. A multiple-baseline across participants ( = 12) single-case experimental design, with randomly allocated baseline phase lengths, quantitatively evaluated ...
Hession CE, Law Smith MJ, Watterson D, Oxley N, Murphy BA. This study aims to investigate the impact of a therapeutic horse riding (HR) intervention and an audiovisual (AV) intervention comprising exposure to equine rhythm and motion on developmental parameters of children with Developmental Coordination Disorder (DCD). The study design was a pretest/post-test. The study took place in three locations across Ireland-St. Michael's Boys School in Mervue, Co Galway, The Hunt Museum in Limerick City, Co. Limerick, and Fettercairn Youth Horse Project in Tallaght, Co. Dublin. Eighty-three children (6-14 years) with a primary diagnosis of DCD. Children m...
Pan Z, Granger DA, Guérin NA, Shoffner A, Gabriels RL.We aimed to determine whether results of our prior randomized control trial [RCT; NCT02301195, (1)] of Therapeutic Horseback Riding (THR) for children and adolescents with autism spectrum disorder (ASD) could be at a different riding center and if treatment effects also included differences in the expression of associations between problem behavior and the activity of the hypothalamic-pituitary-adrenal (HPA) axis. Participants with ASD ( = 16) ages 6-16 years were randomized by nonverbal intelligence quotient to either a 10-week THR group ( = 8) or no horse interaction barn activity (BA) cont...
Sigurjónsdóttir H, Haraldsson H.We explore how herd composition and management factors correlate with frequencies of social interactions in horse groups. Since the welfare of horses correlates with low aggression levels and social contact opportunities, information of this kind is important. The data are a collection of records of social interactions of 426 Icelandic horses in 20 groups of at least eight horses. The complexities and limitations of the data prohibit useful statistical modelling so the results are presented descriptively. Interesting and informative patterns emerge which can be of use both in management and in...
Antwis RE, Lea JMD, Unwin B, Shultz S.Microbiome composition is linked to host functional traits including metabolism and immune function. Drivers of microbiome composition are increasingly well-characterised; however, evidence of group-level microbiome convergence is limited and may represent a multi-level trait (i.e. across individuals and groups), whereby heritable phenotypes are influenced by social interactions. Here, we investigate the influence of spatial structuring and social interactions on the gut microbiome composition of Welsh mountain ponies. We show that semi-feral ponies exhibit variation in microbiome composition ...

Górecka-Bruzda A, Fureix C, Ouvrard A, Bourjade M, Hausberger M.Yawning is rare in herbivores which therefore may be an interesting group to disentangle the potential function(s) of yawning behaviour. Horses provide the opportunity to compare not only animals living in different conditions but also wild versus domestic species. Here, we tested three hypotheses by observing both domestic and Przewalski horses living in semi-natural conditions: (i) that domestic horses may show an elevated rate of yawning as a result of the domestication process (or as a result of life conditions), (ii) that individuals experiencing a higher level of social stress would yawn...
Ringhofer M, Inoue S, Mendonça RS, Pereira C, Matsuzawa T, Hirata S, Yamamoto S.Horses are phylogenetically distant from primates, but considerable behavioral links exist between the two. The sociality of horses, characterized by group stability, is similar to that of primates, but different from that of many other ungulates. Although horses and primates are good models for exploring the evolution of societies in human and non-human animals, fewer studies have been conducted on the social system of horses than primates. Here, we investigated the social system of feral horses, particularly the determinant factors of single-male/multi-male group dichotomy, in light of hypot...
Krueger K, Schneider G, Flauger B, Heinze J.One mechanism to resolve conflict among group members is third party intervention, for which several functions, such as kin protection, alliance formation, and the promotion of group cohesion have been proposed. Still, empirical research on the function of intervention behaviour is rare. We studied 40 cases of intervention behaviour in a field study on 13 semi-wild bachelor horses (Equus ferus przewalskii) in (a) standard social situations, and (b) when new horses joined the group (i.e. introductions). Only interventions in agonistic encounters were analysed. Eight of 13 animals directed inter...
Smith AV, Wilson C, McComb K, Proops L.Signals of dominance and submissiveness are central to conspecific communication in many species. For domestic animals, sensitivities to these signals in humans may also be beneficial. We presented domestic horses with a free choice between two unfamiliar humans, one adopting a submissive and the other a dominant body posture, with vocal and facial cues absent. Horses had previously been given food rewards by both human demonstrators, adopting neutral postures, to encourage approach behaviour. Across four counterbalanced test trials, horses showed a significant preference for approaching the s...
Crowell-Davis SL.The mare is seasonally polyestrus, having an anovulatory period during the short light days of late fall and early winter, and beginning to ovulate as the days become longer during the winter. The complete estrus cycle is typically about 3 weeks, with 5 to 7 days of estrus and approximately 2 weeks of diestrus. When a mare lives within the natural social structure of the horse, i.e. a family band with several adult mares and one or more stallions, estrus is characterized by repeatedly approaching the stallion, frequent urination, deviating the tail away from the perineum, and standing still wi...

Kern-Godal A, Brenna IH, Arnevik EA, Ravndal E.Inclusion of horse-assisted therapy (HAT) in substance use disorder (SUD) treatment is rarely reported. Our previous studies show improved treatment retention and the importance of the patient-horse relationship. This qualitative study used thematic analysis, within a social constructionist framework, to explore how eight patients experienced contextual aspects of HAT's contribution to their SUD treatment. Participants described HAT as a "break from usual treatment". However, four interrelated aspects of this experience, namely "change of focus", "activity", "identity", and "motivation," sugge...
Krüger K, Flauger B.Like many other herbivores, in a natural environment equids feed on rather evenly distributed resources. However, the vegetation in their vast habitats constantly changes. If food is plentiful only little competition occurs over food, and in non-competitive situations domestic horses tend to return to the same feeding site until it is overgrazed. In contrast, they compete over limited food for which the social status of the individuals appears to be important. Especially in ruminants several studies have proved an influence of social organisations, rank, sex and the depletion of feeding sites ...
Pendry P, Carr AM, Smith AN, Roeter SM.There is growing evidence that promoting social competence in youth is an effective strategy to prevent mental, emotional, and behavioral disorders in adulthood. Research suggests that programs delivered in collaboration with schools are particularly effective when they target social and emotional skill building, utilize an interactive instructional style, provide opportunities for youth participation and self-direction, and include explicit attempts to enhance youth social competence. A relatively new but popular approach that incorporates these characteristics is human animal interaction, wh...
Keiper RR.Socially feral horses live in stable social groups characterized by one adult male, a number of adult females, and their offspring up to 2 years of age. Extra males either live by themselves or with other males in bachelor groups. The bands occupy nondefended home ranges that often overlap. Many abnormal behaviors seen in domestic horses occur because some aspect of their normal social behavior cannot be carried out in captivity.

Wolframm IA, Douglas J, Pearson G.Equestrianism is currently facing a range of pressing challenges. These challenges, which are largely based on evolving attitudes to ethics and equine wellbeing, have consequences for the sport's social licence to operate. The factors that may have contributed to the current situation include overarching societal trends, specific aspects of the equestrian sector, and factors rooted in human nature. If equestrianism is to flourish, it is evident that much needs to change, not the least, human behaviour. To this end, using established behaviour change frameworks that have been scientifically val...

Hood J, McDonald C, Wilson B, McManus P, McGreevy P.Whip use in horseracing is increasingly being questioned on ethical, animal welfare, social sustainability, and legal grounds. Despite this, there is weak evidence for whip use and its regulation by Stewards in Australia. To help address this, we characterised whip rule breaches recorded by Stewards using Stewards Reports and Race Diaries from 2013 and 2016 in New SouthWales (NSW) and the Australian Capital Territory (ACT). There were more recorded breaches at Metropolitan (M) than Country (C) or Provincial (P) locations, and by riders of horses that finished first, second, or third than by ri...

Rørvang MV, Christensen JW, Ladewig J, McLean A.Prima facie, the acquisition of novel behaviors in animals through observation of conspecifics seems straightforward. There are, however, various mechanisms through which the behavior of animals can be altered from observing others. These mechanisms range from simple hard-wired contagious processes to genuine learning by observation, which differ fundamentally in cognitive complexity. They range from social facilitation and local enhancement to true social learning. The different learning mechanisms are the subject of this review, largely because research on learning by observation can be conf...
Majecka K, Klawe A.The aim of this study was to explore whether the size of paddocks affected social interactions within a group of horses. Furthermore, the effects of the gender composition in groups on social behavior were investigated. The research was done in a horse-riding center. A total of 78 horses and ponies, forming 3 groups, were included in the study. The time of the observation was divided into 2 periods. The data obtained from the 1st period (the horses were on relatively small paddocks) and the 2nd period (the paddocks were significantly bigger) were compared. The findings uniformly indicated that...
Kieson E, Goma AA, Radi M.Studies show that horses express favoritism through shared proximity and time and demonstrate unique affiliative behaviors such as allogrooming (mutual scratching) with favorite conspecifics. Allogrooming also occurs more frequently during stress and has been observed to occur more frequently in domestic herds than feral. The role of partner preference, lateralization, and duration of allogrooming as measures of social bonding has remained unclear. The present study looked at two socially stable herds of mares (n = 85, n = 115) to determine the frequency, duration, visual field of view and par...
Shimada M, Suzuki N.Although herd size, structure, stability, and social rank among Misaki feral horses have been reported, no studies have been conducted on the affiliative relationships and interactions among members in a Misaki horse herd. The validity of three hypotheses regarding the function of social grooming, the affiliative relationship strengthening hypothesis, the worsened relationship restoring hypothesis, and the grooming parasite removal hypothesis, were tested in a Misaki feral horse () herd in Cape Toi, Japan. All the nine horses in the "6m" herd were investigated in terms of kinship, grooming, ag...
Burla JB, Siegwart J, Nawroth C.Horses’ ability to adapt to new environments and to acquire new information plays an important role in handling and training. Social learning in particular would be very adaptive for horses as it enables them to flexibly adjust to new environments. In the context of horse handling, social learning from humans has been rarely investigated but could help to facilitate management practices. We assessed the impact of human demonstration on the spatial problem-solving abilities of horses during a detour task. In this task, a bucket with a food reward was placed behind a double-detour barrier ...
Ricci-Bonot C, Romero T, Nicol C, Mills D.Social buffering occurs when the presence of one animal attenuates another's stress response during a stressful event and/or helps the subject to recover more quickly after a stressful event. Inconsistent previous results might reflect previously unrecognised contextual influences, such as the nature of the stimulus presented or social factors. We addressed these issues in a two-part study of horses paired with familiar (16 subjects) or unfamiliar (16 subjects) companions. Each subject performed 4 tests in a counterbalanced order: novel object test (static ball)-alone or with companion; and um...
Martos Martinez-Caja A, De Herdt V, Enders-Slegers MJ, Moons CPH.The outbreak of the COVID-19 pandemic has caused dramatic changes to our lifestyle, particularly affecting our ability to interact "in person" with our social network. These changes have had a detrimental effect on the mental welfare of the global population. The international questionnaire "Pets in Lockdown" was designed to investigate whether feelings of loneliness were affecting the mood of people during the COVID-19 lockdown and whether pet ownership may have had a positive influence on both loneliness and general mood. As expected, higher loneliness scores were associated with higher nega...

Janczarek I, Wiśniewska A, Chruszczewski MH, Tkaczyk E, Górecka-Bruzda A.We tested the hypothesis that social defensive responses to the vocalisation of a predator still exist in horses. The recordings of a grey wolf, an Arabian leopard and a golden jackal were played to 20 Konik polski and Arabian mares. Durations of grazing, standing still, standing alert and the number of steps in walk and trot/canter were measured. In one-minute scans, the distances of the focal horse from the reference horse (DIST-RH) and from the nearest loudspeaker (DIST-LS) were approximated. The vocalisation of a leopard aroused the Arabians more than the Koniks (less grazing, stand-still ...
Haigh L, Thompson K.Equestrian activities pose significant head injury risks to participants. Yet, helmet use is not mandatory in Australia outside of selected competitions. Awareness of technical countermeasures and the dangers of equestrian activities has not resulted in widespread adoption of simple precautionary behaviors like helmet use. Until the use of helmets whilst riding horses is legislated in Australia, there is an urgent need to improve voluntary use. To design effective injury prevention interventions, the factors affecting helmet use must first be understood. To add to current understandings of the...
Tomberg C, Petagna M, de Selliers de Moranville LA.Facial micro-expressions are facial expressions expressed briefly (less than 500 ms) and involuntarily. Described only in humans, we investigated whether micro-expressions could also be expressed by non-human animal species. Using the Equine Facial action coding system (EquiFACS), an objective tool based on facial muscles actions, we demonstrated that a non-human species, Equus caballus, is expressing facial micro-expressions in a social context. The AU17, AD38 and AD1 were selectively modulated as micro-expression-but not as standard facial expression (all durations included)-in presence of ...
Sissons JH, Blakemore E, Shafi H, Skotny N, Lloyd DM.Children with autism typically experience difficulties interacting socially with others when compared to their non-autistic peers. Establishing how effective interventions are for improving social functioning is important to help inform what should be offered to children with autism. This study reviewed how effective interventions that involved interaction with a live animal, known as animal-assisted interventions, are in improving social functioning in children with autism. A systematic search of the evidence on this topic found nine studies, which were explored for the effectiveness of anima...
Rosing T, Malka M, Brafman D, Fisher PW.Equine-assisted therapy (EAT) is an increasingly popular form of treatment for people suffering from post-traumatic stress disorder (PTSD) who, for one reason or another, find psychotherapy and other traditional treatment approaches unsuitable or unhelpful. However, the concomitant growth of research in the field is yet to engage with key factors relating to EAT; specifically, there are few studies considering the phenomenological perspective of patients, and the embodied knowledge deriving from the lived experience of PTSD patients who participated in EAT-based intervention programmes. Based ...
