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.
Does work affect personality? A study in horses.
PloS one    February 9, 2011   Volume 6, Issue 2 e14659 doi: 10.1371/journal.pone.0014659
Hausberger M, Muller C, Lunel C.It has been repeatedly hypothesized that job characteristics are related to changes in personality in humans, but often personality models still omit effects of life experience. Demonstrating reciprocal relationships between personality and work remains a challenge though, as in humans, many other influential factors may interfere. This study investigates this relationship by comparing the emotional reactivity of horses that differed only by their type of work. Horses are remarkable animal models to investigate this question as they share with humans working activities and their potential diff...
Differential outcomes of unilateral interferences at birth.
Biology letters    November 17, 2010   Volume 7, Issue 2 177-180 doi: 10.1098/rsbl.2010.0979
de Boyer des Roches A, Durier V, Richard-Yris MA, Blois-Heulin C, Ezzaouïa M, Hausberger M, Henry S.Behavioural modifications, including modifications of emotional reactivity, can occur following early experience such as handling (manual rubbing). Here, we investigated the effects of unilateral tactile stimulation at an early stage on emotional reactions later on. We handled newborn foals intensively on one side of their body. This early unilateral tactile experience had medium-term effects: the reactions of foals to a human approach, when they were 10 days old, differed according to the side stimulated at birth. Fewer right-handled foals accepted contact with humans, they delayed first cont...
Reinforcement as a mediator of the perception of humans by horses (Equus caballus).
Animal cognition    May 21, 2010   Volume 13, Issue 5 753-764 doi: 10.1007/s10071-010-0326-9
Sankey C, Richard-Yris MA, Henry S, Fureix C, Nassur F, Hausberger M.A central question in the interspecific human/animal relationship is how domestic animals perceive humans as a significant element of their environment. In this study, we tested the hypothesis that the use of positive or negative reinforcement in horse training may have consequences on the animals' perception of humans, as a positive, negative or neutral element. Two groups of ponies were trained to walk backwards in response to a vocal order using either positive or negative reinforcement. Heart rate monitors and behavioural observations were used to assess the animals' perception of humans o...
Home care for horses with chronic laminitis.
The Veterinary clinics of North America. Equine practice    April 13, 2010   Volume 26, Issue 1 215-223 doi: 10.1016/j.cveq.2009.12.012
Orsini JA, Wrigley J, Riley P.Home care for horses with chronic laminitis has been discussed rarely in the veterinary literature even though, at any given time, most of us have at least 1 chronic laminitis case in our care that is being managed at home by the owner. Almost all of our knowledge on this aspect of laminitis treatment has been gleaned through experience, by individually working through the medical, ethical, financial, and emotional challenges these cases can present. Much has already been presented on the medical management of the laminitic horse and on strategies for trimming and shoeing the laminitic foot. T...
Could work be a source of behavioural disorders? A study in horses.
PloS one    October 28, 2009   Volume 4, Issue 10 e7625 doi: 10.1371/journal.pone.0007625
Hausberger M, Gautier E, Biquand V, Lunel C, Jégo P.Stress at work, as shown by a number of human studies, may lead to a variety of negative and durable effects, such as impaired psychological functioning (anxiety, depression...). Horses share with humans this characteristic of working on a daily basis and are submitted then to work stressors related to physical constraints and/or more "psychological" conflicts, such as potential controversial orders from the riders or the requirement to suppress emotions. On another hand, horses may perform abnormal repetitive behaviour ("stereotypies") in response to adverse life conditions. In the present st...
Visual laterality in the domestic horse (Equus caballus) interacting with humans.
Animal cognition    July 17, 2009   Volume 13, Issue 2 229-238 doi: 10.1007/s10071-009-0260-x
Farmer K, Krueger K, Byrne RW.Most horses have a side on which they are easier to handle and a direction they favour when working on a circle, and recent studies have suggested a correlation between emotion and visual laterality when horses observe inanimate objects. As such lateralisation could provide important clues regarding the horse's cognitive processes, we investigated whether horses also show laterality in association with people. We gave horses the choice of entering a chute to left or right, with and without the passive, non-interactive presence of a person unknown to them. The left eye was preferred for scannin...
A preliminary study of the effects of handling type on horses’ emotional reactivity and the human-horse relationship.
Behavioural processes    July 8, 2009   Volume 82, Issue 2 202-210 doi: 10.1016/j.beproc.2009.06.012
Fureix C, Pagès M, Bon R, Lassalle JM, Kuntz P, Gonzalez G.Handling is a crucial component of the human-horse relationship. Here, we report data from an experiment conducted to assess and compare the effect of two training methods. Two groups of six Welsh mares were trained during four sessions of 50 min, one handled with traditional exercises (halter leading, grooming/brushing, lifting feet, lunging and pseudo-saddling (using only girth and saddle pad) and the second group with natural horsemanship exercises (desensitization, yielding to body pressure, lunging and free-lunging). Emotional reactivity (ER) and the human-horse relationship (HHR) were as...

Horse (Equus caballus) whinnies: a source of social information.
Animal cognition    May 18, 2009   Volume 12, Issue 5 693-704 doi: 10.1007/s10071-009-0229-9
Lemasson A, Boutin A, Boivin S, Blois-Heulin C, Hausberger M.Many animal species that rely mainly on calls to communicate produce individual acoustic structures, but we wondered whether individuals of species better known as visual communicants, with small vocal repertoires, would also exhibit individual distinctiveness in calls. Moreover, theoretical advances concerning the evolution of social intelligence are usually based on primate species data, but relatively little is known about the social cognitive capacities of non-primate mammals. However, some non-primate species demonstrate auditory recognition of social categories and possess mental represe...
Online detection of an emotional response of a horse during physical activity.
Veterinary journal (London, England : 1997)    April 17, 2009   Volume 181, Issue 1 38-42 doi: 10.1016/j.tvjl.2009.03.017
Jansen F, Van der Krogt J, Van Loon K, Avezzù V, Guarino M, Quanten S, Berckmans D.The objective of this research was to develop a non-invasive method to detect an emotional response of a horse to novelty during physical activity. Two horses performed 20 trials each, in which the horse's heart rate (HR) and physical activity were continuously measured. The relationship between the horse's physical activity and HR was described by a mathematical model allowing online decomposition of the horse's HR into a physical component and a component containing information about its emotional state. Exposure to the novel object resulted in an increase in the emotional component of HR, w...
Equine-facilitated psychotherapy with adult female survivors of abuse.
Journal of psychosocial nursing and mental health services    January 13, 2009   Volume 46, Issue 12 36-42 doi: 10.3928/02793695-20081201-08
Meinersmann KM, Bradberry J, Roberts FB.This qualitative study examined the stories of 5 women who experienced abuse and participated in equine-facilitated psychotherapy (EFP) as part of their recovery. Anecdotal accounts support the effectiveness of EFP with women who have experienced abuse, but there is a lack of supporting research. This study was designed to examine the effectiveness of EFP in the treatment of women who have experienced abuse. Selection criteria included age, experience of abuse, participation in EFP, and ability to understand English. Data analysis identified four patterns in the participants' stories: I Can Ha...
Does horse temperament influence horse-rider cooperation?
Journal of applied animal welfare science : JAAWS    June 24, 2008   Volume 11, Issue 3 267-284 doi: 10.1080/10888700802101254
Visser EK, Van Reenen CG, Blokhuis MZ, Morgan EK, Hassmén P, Rundgren TM, Blokhuis HJ.Cooperation between rider and horse is of major importance in equitation. A balanced team of horse and rider improves (sport) performances and welfare aspects by decreasing stress, frustration, risks of injuries, and accidents. Important features affecting the cooperation are the physical skills, knowledge, and personality of the rider on one hand and the temperament, experience, and physical abilities of the horse on the other. A study with 16 riders and 16 warm-blood riding horses tested the effect of personality of riders and temperament of horses on cooperation between riders and horses. M...
Laterality and emotions: visual laterality in the domestic horse (Equus caballus) differs with objects’ emotional value.
Physiology & behavior    March 12, 2008   Volume 94, Issue 3 487-490 doi: 10.1016/j.physbeh.2008.03.002
De Boyer Des Roches A, Richard-Yris MA, Henry S, Ezzaouïa M, Hausberger M.Lateralization of emotions has received great attention in the last decades, both in humans and animals, but little interest has been given to side bias in perceptual processing. Here, we investigated the influence of the emotional valence of stimuli on visual and olfactory explorations by horses, a large mammalian species with two large monocular visual fields and almost complete decussation of optic fibres. We confronted 38 Arab mares to three objects with either a positive, negative or neutral emotional valence (novel object). The results revealed a gradient of exploration of the 3 objects ...
Effects of a calm companion on fear reactions in naive test horses.
Equine veterinary journal    December 18, 2007   Volume 40, Issue 1 46-50 doi: 10.2746/042516408X245171
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...
A critical review of fear tests used on cattle, pigs, sheep, poultry and horses.
Physiology & behavior    November 30, 2007   Volume 92, Issue 3 340-374 doi: 10.1016/j.physbeh.2007.03.016
Forkman B, Boissy A, Meunier-Salaün MC, Canali E, Jones RB.Fear is arguably the most commonly investigated emotion in domestic animals. In the current review we attempt to establish the level of repeatability and validity found for fear tests used on cattle, pigs, sheep and goats, poultry and horses. We focus the review on the three most common types of fear tests: the arena test (open field), the novel object test, and the restraint test. For some tests, e.g. tonic immobility in poultry, there is a good and broad literature on factors that affect the outcome of the test, the validity of the test and its age dependency. However, there are comparativel...
Assessing equine anxiety-related parameters using an isolation test in combination with a questionnaire survey.
The Journal of veterinary medical science    October 6, 2007   Volume 69, Issue 9 945-950 doi: 10.1292/jvms.69.945
Momozawa Y, Terada M, Sato F, Kikusui T, Takeuchi Y, Kusunose R, Mori Y.The aim of the study was to determine parameters reflecting equine anxiety trait by comparing results obtained in a behavior test and an anxiety score assessed by familiar caretakers in response to a questionnaire. In the behavior test, horses were individually led into a novel room by their caretakers and loosely tethered to decrease excessive movement using the common cross-tying technique with two leads and breakable plastic cords. The horses initially remained with their caretaker for 2 min; the caretaker then left and the subject animal was left alone for 2 min. The latency to break the p...
Healing with horses: fostering recovery from cancer with horses as therapists.
Explore (New York, N.Y.)    June 20, 2006   Volume 2, Issue 3 264-268 doi: 10.1016/j.explore.2006.03.013
Haylock PJ, Cantril CA.Nearly 10 years ago, I looked at a poster exhibit for a nonprofit organization's camping experience for cancer survivors. One of the images in particular remains with me to this day. It was of an elderly man wearing a cowboy hat and the great grin on his wrinkled face as he stood next to a beautiful sorrel horse. The woman at the poster told me the story behind the picture: The man had advanced cancer and had already entered a hospice program, even though he was still physically active. He'd told many people that his biggest regret in life was that he'd never gotten to ride a horse. The photog...
Laterality of horses associated with emotionality in novel situations.
Laterality    June 7, 2006   Volume 11, Issue 4 355-367 doi: 10.1080/13576500600624221
Larose C, Richard-Yris MA, Hausberger M, Rogers LJ.We have established that lateral biases are characteristic of visual behaviour in 65 horses. Two breeds, Trotters and French Saddlebreds aged 2 to 3, were tested on a novel object test. The main finding was a significant correlation between emotionality index and the eye preferred to view the novel stimulus: the higher the emotionality, the more likely that the horse looked with its left eye. The less emotive French Saddlebreds, however, tended to glance at the object using the right eye, a tendency that was not found in the Trotters, although the emotive index was the same for both breeds. Th...
Effects of a therapeutic riding program on at-risk and special education children.
Journal of the American Veterinary Medical Association    January 24, 2006   Volume 228, Issue 1 46-52 doi: 10.2460/javma.228.1.46
Kaiser L, Smith KA, Heleski CR, Spence LJ.To determine the effects of a therapeutic riding program on psychosocial measurements among children considered at risk for poor performance or failure in school or life and among children in special education programs. Methods: Observational study. Methods: 17 at-risk children (6 boys and 11 girls) and 14 special education children (7 boys and 7 girls). Methods: For the at-risk children, anger, anxiety, perceived self-competence, and physical coordination were assessed. For the special education children, anger and cheerfulness were measured, and the children's and their mothers' perceptions ...

Effect of oestrous-cycle stage on the response of mares in a novel object test and isolation test.
Reproduction in domestic animals = Zuchthygiene    September 10, 2005   Volume 40, Issue 5 480-488 doi: 10.1111/j.1439-0531.2005.00611.x
Hedberg Y, Dalin AM, Ohagen P, Holm KR, Kindahl H.In various species, sex, hormonal treatments and oestrous-cycle stage have been shown to affect the animal's response in behavioural tests. Few such studies have been performed in the horse. The main aim of the present study was to investigate whether oestrous-cycle stage affects mares' response to a novel object test and isolation test and, in part, to study whether mares, assumed to suffer from oestrous-related behavioural problems, respond differently in these tests when compared with controls. Twelve mares were tested twice, in oestrus and dioestrus, in a crossover design. Seven behavioura...
Congruence of Actual and Retrospective Reports of Precompetition Emotions in Equestrians.
Journal of sport & exercise psychology    September 1, 2002   Volume 24, Issue 3 271-288 doi: 10.1123/jsep.24.3.271
Tenenbaum G, Lloyd M, Pretty G, Hanin YL.A study was carried out to examine the ability of equestrians to accurately report precompetition emotions and thoughts across varying time delays (3,7, and 14 days) after competition. Forty male and female dressage riders were randomly divided into two equal groups: participants who watched their videotaped precompetition routine before responding to the items, and participants who visualized the precompetition routine without any external aid. Each rider completed several questionnaires which measured emotions, items related to horses, and an open-ended question on thoughts and emotions at t...
Heart rate and heart rate variability during a novel object test and a handling test in young horses.
Physiology & behavior    June 5, 2002   Volume 76, Issue 2 289-296 doi: 10.1016/s0031-9384(02)00698-4
Visser EK, van Reenen CG, van der Werf JT, Schilder MB, Knaap JH, Barneveld A, Blokhuis HJ.Forty-one Dutch Warmblood immature horses were used in a study to quantify temperamental traits on the basis of heart rate (HR) and heart rate variability (HRV) measures. Half of the horses received additional training from the age of 5 months onwards; the other half did not. Horses were tested at 9, 10, 21 and 22 months of age in a novel object and a handling test. During the tests, mean HR and two heart variability indices, e.g. standard deviation of beat-to-beat intervals (SDRR) and root mean square of successive beat-to-beat differences (rMSSD), were calculated and expressed as response va...
Of patients & horses. Equine-facilitated psychotherapy.
Journal of psychosocial nursing and mental health services    May 23, 2002   Volume 40, Issue 5 16-19 doi: 10.3928/0279-3695-20020501-14
Bates A.1. Horses, just by their large, gentle presence, put people therapeutically in touch with the vitality of being alive. 2. People who ordinarily shun physical and emotional closeness often can accept closeness from a horse and through therapy can transfer these skills to their daily lives. 3. The behavior of a sensitive horse display the rider's emotions to the therapist and provides a vehicle the therapist can use to teach the patient coping skills. 4. Therapists with an interest in horses can learn more about how to become involved in an equine-facilitated psychotherapy practice through the N...
Self-consciousness and animal suffering.
Biologist (London, England)    February 24, 2001   Volume 47, Issue 2 77-80 
Morton DB.Animals with relatively highly developed brains are likely to experience some degree of self-awareness and the ability to think. As well as being interesting in its own right, self-consciousness matters from an ethical point of view, since it can give rise to forms of suffering above and beyond the immediate physical sensations of pain or distress. This article surveys the evidence for animal self-consciousness and its implications for animal welfare.
Personality and individual differences in the horse, their significance, use and measurement.
Equine veterinary journal. Supplement    September 15, 1999   Issue 27 10-13 doi: 10.1111/j.2042-3306.1998.tb05137.x
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...
Experimental tests to assess emotionality in horses.
Behavioural processes    September 1, 1997   Volume 40, Issue 3 209-221 doi: 10.1016/s0376-6357(97)00784-5
Wolff A, Hausberger M, Le Scolan N.Different tests were used to assess different aspects of the emotionality of 1-3 year-old horses: arena test; a `novel object' test; and a handling test. In reaction to the test situations no important differences were observed according to age or sex in the behaviour patterns, but clear individual differences were observed within these classes. The arena test seemed to reveal the degree of gregariousness of the animals whereas the results in the two other tests were correlated and seemed to reflect an inherent degree of fearfulness in the horse. Indices were developed that enabled to rank the...

[Heart rate fluctuations in the horse at rest: (1) Investigation of heart rate changes by spectrum analysis].
Comptes rendus de l'Academie des sciences. Serie III, Sciences de la vie    August 1, 1995   Volume 318, Issue 8 859-865 
Clément F, Barrey E.The heart rate fluctuations at rest were studied in order to explore the emotionality of the horses by isolating the influence of the autonomic control. This paper presents a method of spectral analysis which was used to analyse the heart rate variability in the frequency domain. The heartbeat intervals were recorded during 1 h and a series of 1,024 heartbeats was extracted to compute a power spectrum of density. This was obtained by calculating the Fourier transform of the autocorrelation function of the series. This spectral analysis was applied to heart rate recordings in order to illustrat...
