The study of emotions in horses involves understanding the behavioral, physiological, and psychological responses of horses to various stimuli. Emotions in horses can be inferred through observable behaviors, such as vocalizations, body language, and interactions with their environment and other animals. Physiological indicators, including heart rate, cortisol levels, and other stress-related biomarkers, are also used to assess emotional states. This research area explores how emotions affect horse welfare, training outcomes, and human-animal interactions. This page compiles peer-reviewed research studies and scholarly articles that examine the identification, measurement, and implications of emotional states in horses.
Feighelstein M, Riccie-Bonot C, Hasan H, Weinberg H, Rettig T, Segal M, Distelfeld T, Shimshoni I, Mills DS, Zamansky A.Animal affective computing is an emerging new field, which has so far mainly focused on pain, while other emotional states remain uncharted territories, especially in horses. This study is the first to develop AI models to automatically recognize horse emotional states from facial expressions using data collected in a controlled experiment. We explore two types of pipelines: a deep learning one which takes as input video footage, and a machine learning one which takes as input EquiFACS annotations. The former outperforms the latter, with 76% accuracy in separating between four emotional states...
den Boer JC, Klip H, Blonk A, Lenselink M, Kaijdoe SPT, Tielkes M, van Zandbeek A, Bres G, Herinx M, Staal WG, Rommelse N.For people with autism spectrum disorder (ASD), daily life can be highly stressful with many unpredictable events that can evoke emotion dysregulation (ED): a strong difficulty with appropriately negative affect regulation. For some of the patients with ASD, treatment as usual does not prove to be effective for ED. They may be at risk of life-long impairment, development of other disorders and loss of motivation for most regular forms of therapy. A highly promising method that may prove effective for therapy-resistant individuals with ASD is Psychotherapy incorporating horses (PIH). PIH uses t...
Burrell KL, Burford JH, England GCW, Freeman SL.The survival of horses diagnosed with critical colic (requiring referral or euthanasia) relies on rapid and effective decision-making by the owner and veterinary practitioner. Objective: To explore UK horse owners' and veterinary practitioners' experiences of decision-making for critical cases of equine colic. Methods: Qualitative study using a phenomenological approach. Methods: Individual, semi-structured telephone interviews were conducted with 14 horse owners and 13 veterinary practitioners (vets) who had experienced a critical decision (referral or euthanasia) for a horse with colic. A pu...
Amado-Fuentes M, Denche-Zamorano A, Barrios-Fernandez S, Gozalo M.Equine Assisted Interventions (EAIs) integrate the active participation of horses in therapeutic or educational interventions. A bibliometric analysis was carried out on this topic, using traditional bibliometric laws and recommendations. For this purpose, a search on the Web of Science (WoS) Core Collection database was carried out, obtaining 333 documents. Annual publications followed an exponentially increasing trend (R = 86%), pointing out that this topic is a growing interest among researchers, publishers, and journals. The USA was the most productive country worldwide and Jeong-yi Kwon a...
Carlsson IM, Bräutigam Ewe M, Nymberg P, Jormfeldt H.Mental ill health among children and adolescents has increased worldwide. Mental health difficulties from a young age are associated with school absence and educational underachievement. A holistic perspective of treatments besides medical treatment is essential Thus, there is a need for research regarding equine-assisted intervention (EAI). Unassigned: The present study aimed to understand the outcomes of an equine-assisted intervention for children and adolescents with mental ill health from the perspectives of parents and close relatives. Unassigned: This study used a qualitative research d...
Nieforth LO, Leighton SC.The incorporation of animals into interventions focused on military families is a relatively new concept. Though animal-assisted interventions (AAIs) have been studied in the context of military veterans, few studies incorporate members of the military family or focus on the family members' experiences. Unassigned: This systematic review investigates the effects of AAIs on the wellbeing of military family members beyond the veteran themselves through three aims: (1) by describing the characteristics of AAIs for military family members, (2) by evaluating the quality of the methodology present w...
Pearson G.This year BVA Live will, for the first time, feature farm animal and equine CPD. Among the varied topics on offer, Gemma Pearson will be presenting an introduction to equine behavioural medicine, examining the link between emotional and physical health in horses.
Nieforth LO, Kaufman S.Given the nature of horse-human interactions in equine-assisted services (EAS), death of a horse may have significant impacts. In this study, an online survey was distributed to EAS practitioners. The goal of the study was to explore the experiences of practitioners and identify the socioemotional processes that occur upon the death of an equine within an EAS program. Open-ended responses ( = 84) were analyzed qualitatively using a grounded theory and constant-comparative approach. Responses are situated into two themes (1) Processing the death of an equine and (2) Practical implications. Expe...
Moscovice LR, Sobczak B, Niittynen T, Koski SE, Gimsa U.Although best known for its established role in mediating parturition and lactation, the highly-conserved neuropeptide hormone oxytocin also mediates a range of social and stress-buffering processes across mammalian species. Measurements of peripheral oxytocin in plasma have long been considered the gold standard, but there is increasing interest in developing methods to detect oxytocin non-invasively in saliva. Here we present an analytical and biological validation of a novel method to measure salivary oxytocin (sOXT) in an under-studied research group: farm animals. Given their similarities...
Gunnarsson AB, Aurin IE, Holmberg S.Animal-assisted and nature-based interventions in psychosocial treatment for various groups of clients have been studied internationally. However, there is little knowledge about how young adults with autism experience participation in such types of interventions. This clinical study aimed to describe the feasibility of animal-assisted and nature-based activities on a farm as a complementary intervention for young adults with autism and social withdrawal. Methods: The participants were aged 18-30 years, diagnosed with autism and social withdrawal, with no organised occupation during the prev...
Müller-Klein A, Braun MN, Ferreira de Sá DS, Michael T, Link-Dorner U, Lass-Hennemann J.Equine-assisted therapies are becoming increasingly popular for addressing physical and psychological disabilities in clients. The role of the horse's welfare in equine-assisted service receives increasing attention in research. Several studies have shown that horses are able to perceive human emotions and respond to human stress responses. However, no research has yet looked at the other side of the coin-whether and how humans perceive and react to equine stress levels during equine-assisted services. To fill this gap in the research, we employed a within-subjects design, in which horse-naïv...
Fridén L, Hultsjö S, Lydell M, Jormfeldt H.Common mental disorders such as anxiety, depression and stress-related disorders are increasing worldwide, resulting in long-term sick leave and lower quality of life. Traditional treatment is often insufficient to facilitate the recovery process, and the need for holistic interventions that enable successful recovery is evident. Equine-assisted interventions have shown promising results in health promotion among people with mental disorders, and further research is needed to implement them within the range of available care. The aim of the study is therefore to describe experiences of a thera...
Vincent A, Morrissey M, Acri M, Guo F, Hoagwood K.This study examines the effect of volunteering within a Professional Association of Therapeutic Horsemanship International (PATH Intl) premiere accredited center by exploring the experiences of volunteers leading horses in adaptive riding lessons. Adaptive Riding lessons are horseback riding lessons for individuals ages four through the lifespan, with special needs, varying from cognitive, physical, social-emotional, or other challenges. Volunteers directly impact the rider-horse bond by increasing accessibility to horseback riding for individuals with disabilities, fostering a meaningful bond...
Jaramillo FM, Oliveira TM, Silva PEA, Trindade PHE, Baccarin RYA.Horse racing is a major sport practiced worldwide. The environment to which horses are exposed during race meetings can influence their behavior. However, to the best of our knowledge, a method for assessing a horse's response to its surroundings during the pre- and post-race periods has not yet been reported. This study aimed to create a standard list of descriptors for use in a qualitative behavioral assessment (QBA) focused on assessing the emotional expressivity of horses before and after racing events. Unassigned: Seventy pre- or post-race 30-second videos of horses were randomly selected...
Cerebral lateralisation is the tendency for an individual to preferentially use one side of their brain and is apparent in the biased use of paired sensory organs. Horses vary in eye use when viewing a novel stimulus which may be due to different physiological reactions. To understand the interplay between physiology and lateralisation, we presented a novel object (an inflated balloon) to 20 horses while electrocardiogram traces were collected. We measured the amount of time each horse looked at the balloon with each eye. We calculated 'sample entropy' as a measure of non-linear heart rate var...
Jardat P, Liehrmann O, Reigner F, Parias C, Calandreau L, Lansade L.Communication of emotions plays a key role in intraspecific social interactions and likely in interspecific interactions. Several studies have shown that animals perceive human joy and anger, but few studies have examined other human emotions, such as sadness. In this study, we conducted a cross-modal experiment, in which we showed 28 horses two soundless videos simultaneously, one showing a sad, and one a joyful human face. These were accompanied by either a sad or joyful voice. The number of horses whose first look to the video that was incongruent with the voice was longer than their first ...
Janicka W, Wilk I, Próchniak T.Living in a herd has multiple advantages for social species and is a primary survival strategy for prey. The presence of conspecifics, identified as a social buffer, may mitigate the individual stress response. Social isolation is, therefore, particularly stressful for horses, which are gregarious animals. However, they are not equally vulnerable to separation from the group. We tested whether more and less socially dependent horses and independent individuals would differ in their responses to novel and sudden sounds occurring in two contexts: non-social and social motivation. Twenty warmbloo...
Haddy E, Burden F, Raw Z, Rodrigues JB, Zappi Bello JH, Brown J, Kaminski J, Proops L.Belief in animal sentience and the quality of human-animal relationships play a significant role in animal welfare. However, the link between an individual animal's welfare and the beliefs and emotional connection of the owner to the animal is understudied and focussed on single cultures, limiting generalisability. In this study, we explored potential links between owner attitude, beliefs in animal sentience, and working equid welfare across four continents. This study used a welfare assessment protocol alongside a questionnaire exploring owner attitudes to assess 378 participants across six c...
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 ...
Harvey AM, Beausoleil NJ, Ramp D, Mellor DJ.The mental experiences of animals are what characterises their welfare status. The Five Domains Model for assessing welfare aligns with the understanding that physical and mental states are linked. Following measurement of indicators within each of the four physical/functional Domains (1. Nutrition; 2. Physical environment; 3. Health; and 4. Behavioural interactions), the anticipated negative or positive affective consequences (mental experiences) are cautiously inferred and assigned to Domain 5. Those inferences derive credibility from validated knowledge of the underlying systems of physiolo...
Scholler D, Zablotski Y, May A.Stress has a significant impact on equine welfare. There are some studies on the stress response in horses ridden with tight nosebands, but little is known about other stress parameters than cortisol, which potentially could address an emotional component. In this study, blood samples of a total of 74 warmblood horses were used to establish reference values for plasma substance P (SP) concentrations. Moreover, 16 of these warmblood horses were included in a stress model. Four different stress levels (level 1: horses ridden with loose noseband, level 2: tight noseband, level 3: loose noseband a...
Bradshaw-Wiley E, Randle H.Increasing interest in equine welfare has emphasised the need for objective and reliable behavioural indicators of horses' affective state. However, research has yielded mixed results regarding behaviours suited for industry use largely because they are subject to anthropomorphic interpretation. Stabling is commonly used to manage domesticated horses despite research indicating that it can negatively impact horse welfare, but its effect on their affective state is yet to be quantified. Ten adult horses (11.8 ± 4.4 years) were observed either on a day- (DS) or night-stabling (NS) schedule over...
Jardat P, Destrez A, Damon F, Menard-Peroy Z, Parias C, Barrière P, Keller M, Calandreau L, Lansade L.Animals are widely believed to sense human emotions through smell. Chemoreception is the most primitive and ubiquitous sense, and brain regions responsible for processing smells are among the oldest structures in mammalian evolution. Thus, chemosignals might be involved in interspecies communication. The communication of emotions is essential for social interactions, but very few studies have clearly shown that animals can sense human emotions through smell. We used a habituation-discrimination protocol to test whether horses can discriminate between human odors produced while feeling fear vs....
Maurício LS, Leme DP, Hötzel MJ.Stabled horses often experience negative emotions due to the inappropriate living conditions imposed by humans. However, identifying what emotions horses experience and what can trigger positive and negative emotions in stabled horses can be challenging. In this article we present a brief history of the study of emotions and models that explain emotions from a scientific point of view and the physiological bases and functions of emotions. We then review and discuss physiological and behavioral indicators and cognitive bias tests developed to assess emotions in horses. Hormone concentrations, b...
Matias AR, Santos GD, Almeida N.A significant number of institutionalized children have behavior problems. Socio-emotional skills are fundamental for their adaptation and success throughout life and are usually weakened in this population. Equine-assisted services (EAS) are a form of therapeutic mediation that facilitates and requires the practitioner's participation, contributing to the promotion of various psychomotor and socio-emotional dimensions. This study was developed during 17 sessions of EAS with a psychomotor intervention, which took place individually and weekly and lasted approximately 45 min, with three institu...
Dai F, Riva MG, Dalla Costa E, Pascuzzo R, Chapman A, Minero M.To identify feasible indicators to evaluate animals' emotional states as a parameter to assess animal welfare, the present study aimed at investigating the accuracy of free choice profiling (FCP) and fixed list (FL) approach of Qualitative Behaviour Assessment (QBA) in horses during the loading phase of transport. A total of 13 stakeholders were trained to score 2 different sets of videos of mixed breed horses loaded for road transport, using both FCP and FL, in 2 sessions. Generalized Procustes Analysis (GPA) consensus profile explained a higher percentage of variation (80.8%) than the mean o...
Diaz L, Gormley MA, Coleman A, Sepanski A, Corley H, Perez A, Litwin AH.The implementation of equine-assisted services (EAS) during treatment for psychological disorders has been frequently documented; however, little is known about the effect of EAS on outcomes for populations with substance use disorder (SUD). The purpose of this scoping review was to synthesize existing literature reporting the effects of EAS when incorporated into SUD treatment. This review followed guidelines in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist for scoping reviews. A search of four databases (MEDLINE/PubMed, PsycINFO, the Cumulative Ind...
Mattila M, Honkanen S, Sjögren T, Piirainen A, Aartolahti E.Interaction has a multidimensional role in equine-facilitated rehabilitation. Unassigned: The aim of this study was to understand rehabilitees' experiences of interaction during equine-facilitated rehabilitation. Unassigned: Six children and four adults with individual diagnoses or reasons to participate in equine-facilitated rehabilitation were included in this qualitative study. Data were collected by interviewing individually the rehabilitees. A phenomenological Spiegelberg's seven-phase meaning analysis was performed to reveal the meanings. Unassigned: Seven meanings were identified: 1) Tr...
Popescu S, Lazar EA, Borda C, Blaga Petrean A, Mitrănescu E.Despite an increase in awareness of their essential needs, many stallions continue to be kept in conditions limiting their social interactions and movement. To supplement the studies which highlight the effects of these practices on selected aspects of equine mental and physical wellbeing, we aimed to monitor a group of 32 adult intact stallions during their transition from tethered housing with limited outdoor access to free group housing through the lens of their overall welfare, perceived emotional status, and docility toward humans. Over three visits (before the management change, two week...
Starling MJ, Branson N, Cody D, McGreevy PD.Animal training relies heavily on an understanding of species-specific behaviour as it integrates with operant conditioning principles. Following on from recent studies showing that affective states and arousal levels may correlate with behavioural outcomes, we explore the contribution of both affective state and arousal in behavioural responses to operant conditioning. This paper provides a framework for assessing how affective state and arousal may influence the efficacy of operant training methods. It provides a series of three-dimensional conceptual graphs as exemplars to describing putati...
Dai F, Leach M, MacRae AM, Minero M, Costa ED.The Horse Grimace Scale (HGS) is a facial-expression-based pain coding system that enables a range of acute painful conditions in horses to be effectively identified. Using valid assessment methods to identify pain in horses is of a clear importance; however, the reliability of the assessment is highly dependent on the assessors' ability to use it. Training of new assessors plays a critical role in underpinning reliability. The aim of the study was to evaluate whether a 30-minute standardised training program on HGS is effective at improving the agreement between observers with no horse experi...
Sankey C, Henry S, Clouard C, Richard-Yris MA, Hausberger M.The aim of this study was to investigate the impact of training experience on young horses (Equus caballus)' lateralized responses to an approaching human. The results show that the one year old untrained horses display asymmetrical responses to an approaching human, with more negative reactions (escapes, threats) when approached from the left side, while approaches towards the right shoulder elicited more positive behaviors. On the contrary, two years old trained horses reacted equally positively to approaches and contact on both sides. Our findings support those of previous studies investiga...
Valenchon M, Lévy F, Prunier A, Moussu C, Calandreau L, Lansade L.The present study investigates how the temperament of the animal affects the influence of acute stress on the acquisition and reacquisition processes of a learning task. After temperament was assessed, horses were subjected to a stressor before or after the acquisition session of an instrumental task. Eight days later, horses were subjected to a reacquisition session without any stressor. Stress before acquisition tended to enhance the number of successes at the beginning of the acquisition session. Eight days later, during the reacquisition session, contrary to non-stressed animals, horses st...
A human-animal relationship can be developed through subsequent interactions, affected by the positive or negative emotional valence of the proceeding one. Horses implement a process of categorization to classify humans with whom they interact as positive, negative, or neutral stimuli by evaluating the kind of approach and the nature of the contact. In these terms, human-animal interactions are emotionally charged events, eliciting specific emotional states in both subjects involved. Although the human-horse relationship has been mainly investigated through behavioral analysis, physiological i...
Kang KD, Jung TW, Park IH, Han DH.Internet gaming disorder (IGD) has been suggested to be a mental health disorder. Attachment and emotional status in IGD patients are important for understanding the etiology and progression of IGD because both parameters are considered to be associated with the affective network. Equine-assisted activities and therapies (EAAT) have been reported to improve emotional status and attachment in subjects. We hypothesized that EAAT would improve attachment in IGD adolescents with insecure attachment issues and increase functional connectivity (FC) within the affective network. Methods: Subjects com...
Arrazola A, Merkies K.Equine-assisted activities (EAA) for human well-being and health rely on human-horse interactions for therapeutic effect. At-risk participants with mental and emotional difficulties can show poor social skills and functioning relationships, potentially leading to unsuccessful human-horse interaction in EAA. This study addresses the effect of the attachment style (AS) of at-risk adolescents on horse physiology and behaviour during an equine-facilitated learning (EFL) program. Thirty-three adolescents participated in a 10-week EFL program with nine therapy horses (the same therapy horse per adol...
Malcolm R, Ecks S, Pickersgill M.Experiences of autism-spectrum disorder are now increasingly studied by social scientists. Human-animal relations have also become a major focus of social inquiry in recent years. Examining horse-assisted therapy for autistic spectrum disorders, this is the first paper that brings these fields together. Drawing on participant observation and interviews at a UK horse therapy Centre, this article examines how staff and the parents of riders account for the successes and limitations of equine therapy. To the respondents, horses 'open up' autistic children and make possible interactions that seeme...
König von Borstel U, Euent S, Graf P, König S, Gauly M.The aim of the present study was to compare horses' heart rate (HR), heart rate variability (RMSSD, pNN50) and behaviour in the same temperament test when being ridden, led, and released free. Behavioural measurements included scores and linear measurements for reactivity (R), activity (A), time to calm down (T) and emotionality (E), recorded during the approach (1) and/or during confrontation with the stimulus (2). Sixty-five horses were each confronted 3 times (1 ridden, 1 led, 1 free running in balanced order) with 3 novel and/or sudden stimuli. Mixed model analysis indicated that leading r...
Christensen JW, Malmkvist J, Nielsen BL, Keeling LJ.In fear-eliciting situations, horses tend to show flight reactions that can be dangerous for both horse and man. Finding appropriate methods for reducing fearfulness in horses has important practical implications. Objective: To investigate whether the presence of a calm companion horse influences fear reactions in naive subject horses. Objective: The presence of a habituated (calm) companion horse in a fear-eliciting situation can reduce fear reactions in naive subject horses, compared to subject horses with a nonhabituated companion (control). Methods: Minimally handled (n = 36), 2-year-old s...
Kowalik S, Janczarek I, Kędzierski W, Stachurska A, Wilk I.The objective of this study was to assess the effect of relaxing massage on the heart rate (HR) and heart rate variability (HRV) in young racehorses during their first racing season. In the study, 72 Purebred Arabian racehorses were included. The study was implemented during the full race season. The horses from control and experimental groups were included in regular race training 6 days a week. The horses from the experimental group were additionally subject to the relaxing massage 3 days a week during the whole study. HR and HRV were assumed as indicators of the emotional state of the horse...
Rochais C, Sébilleau M, Menoret M, Oger M, Henry S, Hausberger M, Cousillas H.Lateralization of brain functions has been suggested to provide individuals with advantages, such as an increase of neural efficiency. The right hemisphere is likely to be specialized for processing attention for details and the left hemisphere for categorization of stimuli. Thus attentional processes actually may underlie lateralization. In the present study, we hypothesized that the attentional state of horses could be reflected in the lateralization of brain responses. We used i) a recently developed attention test to measure horses' visual attentional responses towards a standardized stimu...
Safryghin A, Hebesberger DV, Wascher CAF.In a number of species, consistent behavioral differences between individuals have been described in standardized tests, e.g., novel object, open field test. Different behavioral expressions are reflective of different coping strategies of individuals in stressful situations. A causal link between behavioral responses and the activation of the physiological stress response is assumed but not thoroughly studied. Also, most standard paradigms investigating individual behavioral differences are framed in a fearful context, therefore the present study aimed to add a test in a more positive context...
Schanz L, Krueger K, Hintze S.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 as...
Contreras-Aguilar MD, Henry S, Coste C, Tecles F, Escribano D, Cerón JJ, Hausberger M.Acute stress induces an array of behavioural reactions in horses that vary between individuals. Attempts to relate behavioural patterns and physiological responses have not always given clear-cut results. Here, we measured the changes in a panel of salivary components: salivary alpha-amylase (sAA), lipase, total esterase (TEA), butyrylcholinesterase (BChE), adenosine deaminase (ADA), and cortisol, and their potential link with horses' behaviours after acute stress. Saliva samples were collected in nine riding horses subjected to a test consisting of opening an umbrella. Saliva sampling was obt...
Sylvia L, West E, Blackburn AM, Gupta C, Bui E, Mahoney T, Duncan G, Wright EC, Lejeune S, Spencer TJ.Equine-assisted activities and therapies (EAATs) have been a growing adjunctive integrative health modality, as they allow participants to practice mindfulness, emotional regulation, and self-mastery or self-esteem building skills. Preliminary evidence suggests that these programs may be helpful in reducing posttraumatic stress disorder (PTSD), anxiety, and depressive symptoms. The current study examines the acceptability of integrating an EAAT program as part of a two-week, intensive clinical program for veterans with PTSD and/or traumatic brain injury (TBI). Methods: A family member or suppo...
Hoagwood K, Vincent A, Acri M, Morrissey M, Seibel L, Guo F, Flores C, Seag D, Peth Pierce R, Horwitz S.Reining in Anxiety (RiA) is a therapeutic program for youth with mild to moderate anxiety delivered in a therapeutic riding setting by Certified Therapeutic Riding Instructors. RiA was developed after a review of the evidence base for youth anxiety, is manualized, and includes five core CBT components: in vivo exposure, cognitive restructuring, youth psychoeducation, relaxation, and caregiver psychoeducation about anxiety. This study extended findings from a prior RCT that examined (1) the feasibility of collecting saliva samples from horses and children to measure stress (cortisol) and relaxa...
Marr I, Farmer K, Krüger K.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 ...
Kern-Godal A, Brenna IH, Kogstad N, Arnevik EA, Ravndal E.A good therapeutic relationship is a strong predictor of successful treatment in addiction and other psychological illness. Recent studies of horse-assisted therapy (HAT) have drawn attention to the importance of the client's relationship to the horse in psychotherapy. Few have reported on the patient's own perspective and none have reported specifically on the human-horse relationship in substance use disorder (SUD) treatment and its implications for health and well-being. Objective: This article explores SUD patients' own experience of their relationship with the horse and their perceptions ...
Fields B, Bruemmer J, Gloeckner G, Wood W.Institutional facilities face challenges providing experiences to residents with dementia that promote participation in meaningful activities. Guided by the Lived Environment Life Quality Model, this study investigated associations between 9 different activity situations-one an equine-assisted activities program (EAAP)-and positive, negative, and neutral behavioral indicators of quality of life (QoL) in 6 residents with dementia who expressed an interest in horses. Direct observational data were collected for 4 hours twice weekly over 8 weeks. Using χ tests, differences across activity situat...
Alexander SL, Irvine CH, Livesey JH, Donald RA.A non-surgical, non-stressful technique was used for collection of pituitary venous blood from five conscious horses every minute for two 10-min periods before and during isolation from the herd, which caused a predictable, yet humane and physiological, emotional stress. Pituitary blood was also sampled every 5 min for two approximately 90-min periods before and after isolation, while jugular blood was sampled every 15 min throughout the experiment. During isolation, all horses became agitated, hyperventilating and sweating. Packed red cell volume increased, as did pituitary venous concentrati...
Demarie S, Galvani C, Billat VL.The aim of the present study was to quantify the impact of training restrictions, due to COVID-19 sanitary emergency, on physical and emotional strain of horse-riding Eventing competitions before and after eight weeks of lockdown. Performance was assessed by the penalty points attained, anxiety by the Competitive State Anxiety Inventory-2, strain by the Rating of Perceived Exertion (RPE) method. Moreover, Heart Rate was continuously monitored for fifty-four female national level Eventing horse-riders. Lockdown decreased performance outcome of horse-riders in Eventing competitions up to six wee...
Mengoli M, Pageat P, Lafont-Lecuelle C, Monneret P, Giacalone A, Sighieri C, Cozzi A.Modern day horse-human relationships entail different types of sport and riding activities, which all require learning. In evaluating the interaction between learning and emotions, studying normal coping strategies or adaptive responses to the surroundings is critical. 34 horses were involved in a cognitive test, in the absence of physical effort, to analyze performance, as well as physiological and behavioral responses related to learning, memorization and recall, associated to the capacity to reverse a learned model. Synthetic Equine Appeasing Pheromone (EAP) was used in 17 horses in order t...
Baragli P, Demuru E, Scopa C, Palagi E.Mirror Self-Recognition (MSR) unveils complex cognitive, social and emotional skills and it has been found only in humans and few other species, such as great apes, dolphins, elephants and magpies. In this pilot study, we tested if horses show the capacity of MSR. Four subjects living socially under naturalistic conditions were selected for the experiment. We adopted the classical mark test, which consists in placing a coloured mark on an out-of-view body part, visible only through mirror inspection. If the animal considers the image as its own, it will use its reflection to detect the mark an...
Haddy E, Burden F, Raw Z, Rodrigues JB, Zappi Bello JH, Brown J, Kaminski J, Proops L.Belief in animal sentience and the quality of human-animal relationships play a significant role in animal welfare. However, the link between an individual animal's welfare and the beliefs and emotional connection of the owner to the animal is understudied and focussed on single cultures, limiting generalisability. In this study, we explored potential links between owner attitude, beliefs in animal sentience, and working equid welfare across four continents. This study used a welfare assessment protocol alongside a questionnaire exploring owner attitudes to assess 378 participants across six c...
Alterisio A, Baragli P, Aria M, D'Aniello B, Scandurra A.In order to explore the decision-making processes of horses, we designed an impossible task paradigm aimed at causing an expectancy violation in horses. Our goals were to verify whether this paradigm is effective in horses by analyzing their motivation in trying to solve the task and the mode of the potential helping request in such a context. In the first experiment, 30 horses were subjected to three consecutive conditions: no food condition where two persons were positioned at either side of a table in front of the stall, solvable condition when a researcher placed a reachable reward on the ...
Mills DS.The biological diversity of a species gives rise to individual differences in behavioural tendency. Traditionally, this variation has been considered to be of little scientific importance or value, but the description and quantification of the fundamental basis of this variability is relevant to many aspects of equine science. The reliable identification of these features may allow the development of more accurate diagnostic and prognostic indicators for a range of clinical diseases. Biologically based traits also provide a more rational basis for selective management and breeding programmes i...
Christensen JW, Ahrendt LP, Malmkvist J, Nicol C.The mechanisms underlying individual variation in learning are key to understanding the development of cognitive abilities. In humans and primates, curiosity has been suggested as an important intrinsic factor that enhances learning, whereas in domesticated species research has primarily identified factors with a negative effect on cognitive abilities, such as stress and fearfulness. This study presents the first evidence of a link between object-directed curiosity and learning performance in young horses in two very different learning tasks (visual discrimination and pressure-release). We exp...
Masko M, Domino M, Lewczuk D, Jasinski T, Gajewski Z.A treadmill is an important tool in the equine analysis of gait, lameness, and hoof balance, as well as for the evaluation of horse rehabilitation or poor performance including dynamic endoscopy. Before all of these uses, horses have to be habituated to a treadmill locomotion. We used principal component analysis to evaluate the relationship between aspects of the horse's temperament and emotional response, and progress in the behavioral habituation to a treadmill. Fourteen horses were tested, by the same familiar handler, using the novel object test, the handling test, and both positive and n...
Maigrot AL, Hillmann E, Briefer EF.Discrimination and perception of emotion expression regulate interactions between conspecifics and can lead to emotional contagion (state matching between producer and receiver) or to more complex forms of empathy (e.g., sympathetic concern). Empathy processes are enhanced by familiarity and physical similarity between partners. Since heterospecifics can also be familiar with each other to some extent, discrimination/perception of emotions and, as a result, emotional contagion could also occur between species. Here, we investigated if four species belonging to two ungulate Families, Equidae (d...
