Topic:Emotions

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.
Are Horses (Equus caballus) Sensitive to Human Emotional Cues?
Animals : an open access journal from MDPI    August 29, 2019   Volume 9, Issue 9 630 doi: 10.3390/ani9090630
Baba C, Kawai M, Takimoto-Inose A.Emotions are important for social animals because animals' emotions function as beneficial cues to identify valuable resources such as food or to avoid danger by providing environmental information. Emotions also enable animals to predict individuals' behavior and determine how to behave in a specific context. Recently, several studies have reported that dogs are highly sensitive to not only conspecific but also human emotional cues. These studies suggest that domestication may have affected such sensitivity. However, there are still few studies that examine whether other domesticated animals,...
Horses associate individual human voices with the valence of past interactions: a behavioural and electrophysiological study.
Scientific reports    August 9, 2019   Volume 9, Issue 1 11568 doi: 10.1038/s41598-019-47960-5
Brain lateralization is a phenomenon widely reported in the animal kingdom and sensory laterality has been shown to be an indicator of the appraisal of the stimulus valence by an individual. This can prove a useful tool to investigate how animals perceive intra- or hetero-specific signals. The human-animal relationship provides an interesting framework for testing the impact of the valence of interactions on emotional memories. In the present study, we tested whether horses could associate individual human voices with past positive or negative experiences. Both behavioural and electroencephalo...
The Impact of Equine-Assisted Therapy on Equine Behavioral and Physiological Responses.
Animals : an open access journal from MDPI    July 1, 2019   Volume 9, Issue 7 409 doi: 10.3390/ani9070409
Mendonça T, Bienboire-Frosini C, Menuge F, Leclercq J, Lafont-Lecuelle C, Arroub S, Pageat P.Equine-assisted therapies (EATs) have been widely used in the treatment of patients with mental or physical conditions. However, studies on the influence of equine-assisted therapy (EAT) on equine welfare are very recent, and the need for further research is often highlighted. The aim of this study was to investigate whether EAT creates negative or positive emotions in horses, and the influence of patients' expectations (one group of patients had physical and psychological expectations and one group of patients had only psychological expectations) on horses' emotional responses. Fifty-eight pa...
An Exploration of the Mechanism of Action of an Equine-Assisted Intervention.
Animals : an open access journal from MDPI    May 31, 2019   Volume 9, Issue 6 303 doi: 10.3390/ani9060303
Hemingway A, Carter S, Callaway A, Kavanagh E, Ellis S.Though long alluded to, there is now an accumulation of evidence of the vital contribution that emotion makes to learning. Within this broad advance in understanding is a growing body of research emphasising the embodied nature of this emotion-based learning. The study presented here is a pilot study using a mixed-method approach (combining both physiological and experiential methodologies) to give a picture of the "emotional landscape" of people's learning through the intervention under study. This has allowed researchers to examine mediating pathways that may underlie any effects of an equin...
Sex and Age Don’t Matter, but Breed Type Does-Factors Influencing Eye Wrinkle Expression in Horses.
Frontiers in veterinary science    May 29, 2019   Volume 6 154 doi: 10.3389/fvets.2019.00154
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...
Testing for Behavioral and Physiological Responses of Domestic Horses (Equus caballus) Across Different Contexts – Consistency Over Time and Effects of Context.
Frontiers in psychology    April 18, 2019   Volume 10 849 doi: 10.3389/fpsyg.2019.00849
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...

The Impact of Equine Therapy and an Audio-Visual Approach Emphasizing Rhythm and Beat Perception in Children with Developmental Coordination Disorder.
Journal of alternative and complementary medicine (New York, N.Y.)    February 21, 2019   Volume 25, Issue 5 535-541 doi: 10.1089/acm.2017.0242
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...
Farm Animal Cognition-Linking Behavior, Welfare and Ethics.
Frontiers in veterinary science    February 12, 2019   Volume 6 24 doi: 10.3389/fvets.2019.00024
Nawroth C, Langbein J, Coulon M, Gabor V, Oesterwind S, Benz-Schwarzburg J, von Borell E.Farm animal welfare is a major concern for society and food production. To more accurately evaluate animal farming in general and to avoid exposing farm animals to poor welfare situations, it is necessary to understand not only their behavioral but also their cognitive needs and capacities. Thus, general knowledge of how farm animals perceive and interact with their environment is of major importance for a range of stakeholders, from citizens to politicians to cognitive ethologists to philosophers. This review aims to outline the current state of farm animal cognition research and focuses on u...
Perfect Riders: Personality, Perfectionism, and Mental Health in Norwegian Competition Riders.
Journal of equine veterinary science    February 6, 2019   Volume 75 82-89 doi: 10.1016/j.jevs.2019.01.016
Træen B, Finstad KS, Røysamb E.The purpose of the study was to elucidate the relationship between personality traits, perfectionism, and mental health (self-efficacy, positive emotions) among competition riders. Data were collected by online questionnaires among 662 licensed competition riders in Norway. The results showed that riders who were high on conscientiousness and low on neuroticism had better mental health than other riders. Self-oriented perfectionism predicted mental health and mediated partly the associations between personality traits and mental health. Socially prescribed perfectionism had no association with...
Why Should Human-Animal Interactions Be Included in Research of Working Equids’ Welfare?
Animals : an open access journal from MDPI    January 30, 2019   Volume 9, Issue 2 42 doi: 10.3390/ani9020042
Luna D, Tadich TA.The livelihood of working horses' owners and their families is intimately linked to the welfare of their equids. A proper understanding of human-animal interactions, as well as the main factors that modulate them, is essential for establishing strategies oriented to improve the welfare of animals and their caretakers. To date, there is still a paucity of research dedicated to the identification and assessment of the human psychological attributes that affect the owner⁻equine interaction, and how these could affect the welfare of working equids. However, some studies have shown that empathy, ...
Austrian Veterinarians’ Attitudes to Euthanasia in Equine Practice.
Animals : an open access journal from MDPI    January 30, 2019   Volume 9, Issue 2 44 doi: 10.3390/ani9020044
Springer S, Jenner F, Tichy A, Grimm H.Euthanasia of companion animals is a challenging responsibility in the veterinary profession since veterinarians have to consider not only medical, but also legal, economic, emotional, social, and ethical factors in decision-making. To this end; an anonymous questionnaire-based survey of Austrian equine veterinarians examines the attitudes to the euthanasia of equine patients in a range of scenarios; to identify factors which may influence decisions on the ending of a horse's life. This paper describes the distributions of demographic and attitude variables. Mann-Whitney U tests were used to t...
Use of Music Therapy in Aiding the Relaxation of Geriatric Horses.
Journal of equine veterinary science    December 21, 2018   Volume 78 89-93 doi: 10.1016/j.jevs.2018.12.011
Wiśniewska M, Janczarek I, Wilk I, Wnuk-Pawlak E.The aim of the study was to evaluate the effect of music therapy on changes in the level of parameters describing heart rate (HR) and heart rate variability (HRV) as excitability indicators in geriatric horses. The study involved 20 warmblood geriatric horses, aged 20 years or more. Animals were kept in two identical stables in one facility. Horses from stable No. 1 were considered the experimental group, whereas horses from stable No. 2 constituted a control group. The experiment consisted in playing relaxation new age music to the horses in the experimental group for 28 days use special so...
Adolescents’ Affective and Physiological Regulation Shape Negative Behavior During Challenging Equine Assisted Learning Activities.
Frontiers in veterinary science    December 4, 2018   Volume 5 300 doi: 10.3389/fvets.2018.00300
Pendry P, Carr AM, Vandagriff JL.This study examined associations between adolescents' ( = 59; = 11.63) diurnal and momentary activity of the Hypothalamic Pituitary Adrenal (HPA) axis as marked by salivary cortisol, and affective and behavioral responses to their first, mounted equine assisted learning (EAL) activity. The introduction to riding occurred during the fifth week of an 11-week EAL program for at-risk and typically developing adolescents. Before the 11-week program began, participants collected 6 salivary cortisol samples at prescribed times (wakeup, 4 p.m., bedtime) over 2 days, from which indices of diurnal cor...
Physiological outcomes of calming behaviors support the resilience hypothesis in horses.
Scientific reports    November 30, 2018   Volume 8, Issue 1 17501 doi: 10.1038/s41598-018-35561-7
Scopa C, Palagi E, Sighieri C, Baragli P.To manage a stressful stimulus animals react both behaviorally and physiologically to restore the homeostasis. In stable horses, a stressful stimulus can be represented by social separation, riding discomfort or the presence of novel objects in their environment. Although Heart Rate Variability is a common indicator of stress levels in horses, the behavioral mechanisms concurrently occurring under stressful conditions are still unknown. The sudden inflation of a balloon was administered to 33 horses. Video-recording of self-directed behaviors (snore, vacuum chewing, snort, head/body shaking) a...
Evidence for Right-Sided Horses Being More Optimistic than Left-Sided Horses.
Animals : an open access journal from MDPI    November 22, 2018   Volume 8, Issue 12 219 doi: 10.3390/ani8120219
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 ...
A Case for the Interspecies Transfer of Emotions: A Preliminary Investigation on How Humans Odors Modify Reactions of the Autonomic Nervous System in Horses. Lanata A, Nardelli M, Valenza G, Baragli P, DrAniello B, Alterisio A, Scandurra A, Semin GR, Scilingo EP.We examined the Autonomic Nervous System (ANS) activity of horses in response to human body odors (BOs) produced under happy and fear states. The ANS response of horses was analyzed in terms of Heart Rate Variability (HRV) features extracted in the frequency domain. Our results revealed that human BOs induce sympathetic and parasympathetic changes and stimulate horses emotionally, suggesting interspecies transfer of emotions via BOs. These preliminary findings open the way to measure changes in horse's ANS dynamics in response to human internal states via human BOs, and allow us to better unde...
Efficacy of equine-assisted psychotherapy in veterans with posttraumatic stress disorder.
Journal of integrative medicine    November 16, 2018   Volume 17, Issue 1 14-19 doi: 10.1016/j.joim.2018.11.001
Burton LE, Qeadan F, Burge MR.Posttraumatic stress disorder (PTSD) is a common and debilitating disorder among war veterans. Although complementary and alternative therapies are gaining acceptance in the treatment of PTSD, the efficacy of animal-based therapies in this disorder is unknown. The goal of equine-assisted psychotherapy (EAP) is to improve the social, emotional, and/or cognitive functions of individuals with PTSD. Objective: This study aims to explore the effects of EAP on PTSD symptoms. We hypothesized that veterans with PTSD who participate in a standardized EAP program for 1 h per week for 6 weeks would exp...
Reliability and Validity Assessment of the Observation of Human-Animal Interaction for Research (OHAIRE) Behavior Coding Tool.
Frontiers in veterinary science    November 8, 2018   Volume 5 268 doi: 10.3389/fvets.2018.00268
Guérin NA, Gabriels RL, Germone MM, Schuck SEB, Traynor A, Thomas KM, McKenzie SJ, Slaughter V, O'Haire ME.The Observation of Human-Animal Interaction for Research (OHAIRE) is a coding tool developed to capture the behavior of children when interacting with social partners and animals in naturalistic settings. The OHAIRE behavioral categories of focus are emotional displays, social communication behaviors toward adults and peers, behaviors directed toward animals or experimental control objects, and interfering behaviors. To date, the OHAIRE has been used by 14 coders to code 2,732 min of video across four studies with a total of 201 participants ages 5 to 18 years ( = 10.1, = 2.5). Studies involv...
Memories of emotional expressions in horses.
Learning & behavior    October 20, 2018   Volume 47, Issue 3 191-192 doi: 10.3758/s13420-018-0363-9
Amici F.Proops, Grounds, Smith, and McComb (2018) suggest that horses remember previous emotional expressions of specific humans, and use these memories to adjust their behavior in future social interactions. Despite some methodological shortcomings, this study raises important questions on the complexity of social interactions in nonhuman animals, which surely deserve further attention.
Facial expression and oxytocin as possible markers of positive emotions in horses.
Scientific reports    October 2, 2018   Volume 8, Issue 1 14680 doi: 10.1038/s41598-018-32993-z
Lansade L, Nowak R, Lainé AL, Leterrier C, Bonneau C, Parias C, Bertin A.Behavioural and physiological markers of discrete positive emotions remain little investigated in animals. To characterise new markers in horses, we used tactile stimulations to induce emotional situation of contrasting valence. In the Gentle grooming group (G, N = 13) horses were gently groomed during 11 sessions on the body areas they appreciated the most. Horses in the Standard grooming group (S, N = 14) were groomed using a fixed procedure, reported to induce avoidance reactions in some horses. At session 11, G horses expressed significantly more contact-seeking behaviours than S h...
A qualitative exploration of post-acute stroke participants’ experiences of a multimodal intervention incorporating horseback riding.
PloS one    September 20, 2018   Volume 13, Issue 9 e0203933 doi: 10.1371/journal.pone.0203933
Pohl P, Carlsson G, Bunketorp Käll L, Nilsson M, Blomstrand C.Multimodal rehabilitation interventions delivered in late phase of stroke recovery involve physical (motor and sensory), social, and cognitively challenging activities. Horseback riding can be incorporated within such interventions, leading to meaningful long-term improvements when applied to individuals with moderate levels of disability. There is a lack of research illuminating stroke survivors' experiences and perceptions of horseback riding in the context of multimodal interventions. To explore stroke survivors' experiences of participation in a multimodal group-based intervention that inc...
Companion animals and human health: benefits, challenges, and the road ahead for human-animal interaction.
Revue scientifique et technique (International Office of Epizootics)    September 14, 2018   Volume 37, Issue 1 71-82 doi: 10.20506/rst.37.1.2741
Friedman E, Krause-Parello CA.There is ample evidence that human-animal interaction (HAI) is associated with health. Studies encompass three general categories: those that compare companion animal owners with individuals who do not own companion animals, those examining brief, 'one-off' contacts with animals, and those that review animal-assisted interventions. The health benefits demonstrated typically include reductions in depression and loneliness, while enhancing social interaction or social skills, and decreasing anxiety and arousal. Other health benefits associated with companion animals include the promotion of exer...
Snort acoustic structure codes for positive emotions in horses.
Die Naturwissenschaften    September 12, 2018   Volume 105, Issue 9-10 57 doi: 10.1007/s00114-018-1582-9
Stomp M, Leroux M, Cellier M, Henry S, Hausberger M, Lemasson A.While the vocal coding of human and animal internal states has been widely studied, the possible acoustic expression of "positive" emotions remains poorly known. Recent studies suggest that snorts (non-vocal sounds produced by the air expiration through the nostrils) appear to be reliable indicators of positive internal states in several ungulate species. Here, we hypothesised in horses that the acoustic structure of the snort could vary with the subjects' current emotional state. Indeed, a preliminary sound analysis of snorts let us suggest structure variations related to the presence of puls...
Domestic horses (Equus caballus) discriminate between negative and positive human nonverbal vocalisations.
Scientific reports    August 29, 2018   Volume 8, Issue 1 13052 doi: 10.1038/s41598-018-30777-z
Smith AV, Proops L, Grounds K, Wathan J, Scott SK, McComb K.The ability to discriminate between emotion in vocal signals is highly adaptive in social species. It may also be adaptive for domestic species to distinguish such signals in humans. Here we present a playback study investigating whether horses spontaneously respond in a functionally relevant way towards positive and negative emotion in human nonverbal vocalisations. We presented horses with positively- and negatively-valenced human vocalisations (laughter and growling, respectively) in the absence of all other emotional cues. Horses were found to adopt a freeze posture for significantly longe...
Emotional excitability and behaviour of horses in response to stroking various regions of the body.
Animal science journal = Nihon chikusan Gakkaiho    August 28, 2018   Volume 89, Issue 11 1599-1608 doi: 10.1111/asj.13104
Janczarek I, Stachurska A, Wilk I, Krakowski L, Przetacznik M, Zastrzeżyńska M, Kuna-Broniowska I.Touching the skin by gentle stroking is frequently used to reward horses. The objective of the study was to examine emotional excitability and behaviour of horses in response to stroking different regions of their bodies. The study included 15 adult warmbloods and 15 adult ponies, nine geldings and six mares within each type of horse. First, a novel-object test was conducted. For five successive days, one of five regions of the horse's body was stroked on each side for 5 min. Heart rate and heart rate variability were monitored at rest, during the test and stroking. Simultaneously, horse beha...
Could the Visual Differential Attention Be a Referential Gesture? A Study on Horses (Equus caballus) on the Impossible Task Paradigm.
Animals : an open access journal from MDPI    July 17, 2018   Volume 8, Issue 7 120 doi: 10.3390/ani8070120
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 ...
An unexpected acoustic indicator of positive emotions in horses.
PloS one    July 11, 2018   Volume 13, Issue 7 e0197898 doi: 10.1371/journal.pone.0197898
Stomp M, Leroux M, Cellier M, Henry S, Lemasson A, Hausberger M.Indicators of positive emotions are still scarce and many proposed behavioural markers have proven ambiguous. Studies established a link between acoustic signals and emitter's internal state, but few related to positive emotions and still fewer considered non-vocal sounds. One of them, the snort, is shared by several perrisodactyls and has been associated to positive contexts in these species. We hypothesized that this could be also the case in horses. In this species, there is a clear need for a thorough description of non-vocal acoustic signals (snorts, snores or blows are often used interch...
Attentional state and brain processes: state-dependent lateralization of EEG profiles in horses.
Scientific reports    July 5, 2018   Volume 8, Issue 1 10153 doi: 10.1038/s41598-018-28334-9
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...
Cross-modal perception of human emotion in domestic horses (Equus caballus).
Scientific reports    June 21, 2018   Volume 8, Issue 1 8660 doi: 10.1038/s41598-018-26892-6
Nakamura K, Takimoto-Inose A, Hasegawa T.Humans have domesticated many kinds of animals in their history. Dogs and horses have particularly close relationships with humans as cooperative partners. However, fewer scientific studies have been conducted on cognition in horses compared to dogs. Studies have shown that horses cross-modally distinguish human facial expressions and recognize familiar people, which suggests that they also cross-modally distinguish human emotions. In the present study, we used the expectancy violation method to investigate whether horses cross-modally perceive human emotions. Horses were shown a picture of a ...
