Title Stability over situations in temperamental traits of horses as revealed by experimental and scoring approaches Type Journal Article
Year 1997 Publication Behavioural Processes Abbreviated Journal Behav. Process.
Volume 41 Issue 3 Pages 257-266
Keywords (down) Behavioural tests; Horse; Ratings; Temperament
Abstract Individual behavioural reactions of adult horses in a variety of experimental tests were compared with ratings by riding teachers. The tests were made in a non working situation, with the animals being released in an arena, a box (arena test, new object test, learning tests) or handled (new object/handling situation). The traits rated by teachers were fearfulness, nervousness, gregariousness and learning abilities at work (ridden or handled). Despite a great homogeneity in the reactions exhibited by the horses in the different situations, large individual differences were present. Correlations appeared between the reactivity in the arena test and the score of gregariousness, between the reactivity in the novel object test and the rating of nervousness when ridden, between the results in the handling test and the rating of general fearfulness and between the ability to memorise an instrumental task and the score of general learning ability. Such results strengthen the idea that there are underlying behavioural dispositions that are stable across situations and that the experimental tests may be good predictors of the temperament in untrained animals.

Title A note on the time budget and social behaviour of densely housed horses: A case study in Arab breeding mares Type Journal Article
Year 2008 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 112 Issue 1-2 Pages 196-200
Keywords (down) Behavioural repertoire; Time budget; Mare; Social behaviour; Density
Abstract We observed a high-density herd (200 mares/ha) of 44 Arab breeding mares, while in a bare paddock in Tunisia. Twenty-minute animal focal samples and scan sampling were used to determine the time budget of the mares during the period from 9 a.m. to 3 p.m. and study their social behaviour. The data obtained reveal restricted behavioural repertoires with missing behaviour like rolling, allogrooming and lying down; unusual time budgets with a high frequency of locomotion that constitutes the most frequent activity (27.9 ± 19.47%) of the mares. Social interactions were restricted to agonistic interactions but despite the high stocking density, aggressions were not that frequent among mares.

Title Laterality and emotions: visual laterality in the domestic horse (Equus caballus) differs with objects' emotional value Type Journal Article
Year 2008 Publication Physiology & Behavior Abbreviated Journal Physiol. Behav.
Volume 94 Issue 3 Pages 487-490
Keywords (down) Animals; Animals, Newborn; Behavior, Animal/physiology; Dominance, Ocular/*physiology; *Emotions; Exploratory Behavior/physiology; Female; Horses/*physiology; Olfactory Pathways/physiology; Pattern Recognition, Visual/*physiology; Photic Stimulation; Pregnancy; Statistics, Nonparametric; Visual Fields/physiology
Abstract 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 according to their emotional value and a clear asymmetry in visual exploration. When exploring the novel object, mares used preferentially their right eyes, while they showed a slight tendency to use their left eyes for the negative object. No asymmetry was evidenced for the object with the positive valence. A trend for an asymmetry in olfactory investigation was also observed. Our data confirm the role of the left hemisphere in assessing novelty in horses like in many vertebrate species and the possible role of the right hemisphere in processing negative emotional responses. Our findings also suggest the importance of both hemispheres in the processing positive emotions. This study is, to our knowledge, the first to demonstrate clearly that the emotional valence of a stimulus induces a specific visual lateralization pattern.

Title Influence of various early human-foal interferences on subsequent human-foal relationship Type Journal Article
Year 2006 Publication Developmental psychobiology Abbreviated Journal Dev Psychobiol
Volume 48 Issue 8 Pages 712-718
Keywords (down) Animal Husbandry/methods; Animals; Animals, Newborn/*psychology; Animals, Suckling/*psychology; Behavior, Animal; Female; *Handling (Psychology); Horses/*psychology; Humans; Mothers/psychology; *Object Attachment; Species Specificity
Abstract Whereas the way animals perceive human contact has been particularly examined in pet animals, a small amount of investigations has been done in domestic ungulates. It was nevertheless assumed that, as pet animals, non-aggressive forms of tactile contact were as well rewarding or positive for these species, even though the features of intraspecific relationships in pet animals and domestic ungulates may be to some extent different.We test here the hypothesis that horses may not consider physical handling by humans as a positive event. When comparing different early human-foal interactions, we found that early exposure to a motionless human enhanced slightly foals reactions to humans whereas forced stroking or handling in early life did not improve later human-foal relation. Foals that were assisted during their first suckling (e.g., brought to the dam's teat) even tended to avoid human approach at 2 weeks, and physical contact at 1 month of age.We argue that interspecies differences may exist in how tactile stimulation is perceived. It may be important for the establishment of a bond that a young animal is active in the process and able, through its behavioral responses, to help define what is positive for it. This way of investigation may have important general implications in how we consider the development of social relations, both within and between species.

Title Laterality of horses associated with emotionality in novel situations Type Journal Article
Year 2006 Publication Laterality Abbreviated Journal Laterality
Volume 11 Issue 4 Pages 355-367
Keywords (down) Affect/*physiology; Animals; Brain/*physiology; Female; Functional Laterality/*physiology; Horses; Male; *Social Behavior; *Social Environment
Abstract 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. The youngest French Saddlebreds did not show this trend. These results are discussed in relation to the different training practices for the breeds and broader findings on lateralisation in different species.

Title Interplay between environmental and genetic factors in temperament/personality traits in horses (Equus caballus) Type Journal Article
Year 2004 Publication Journal of Comparative Psychology Abbreviated Journal J Comp Psychol
Volume 118 Issue 4 Pages 434-446
Keywords (down) *Affect; Animals; Behavior, Animal/*physiology; *Environment; Female; Horses/*psychology; Learning; Male; Memory/physiology
Abstract The aim of the present study was to broach the question of the relative influence of different genetic and environmental factors on different temperament/personality traits of horses (Equus caballus). The researchers submitted 702 horses to standardized experimental tests and investigated 9 factors, either genetic or environmental. Genetic factors, such as sire or breed, seemed to influence more neophobic reactions, whereas environmental factors, such as the type of work, seemed to play a more dominant role in reactions to social separation or learning abilities. Additive effects were evident, showing how environmental factors may modulate behavioral traits. This study constitutes a first step toward understanding the relative weights of genetic factors and how the environment may intervene in determining individual behavioral characteristics.

Title Socially dependent auditory laterality in domestic horses (Equus caballus) Type Journal Article
Year 2009 Publication Animal Cognition Abbreviated Journal Anim. Cogn.
Volume 12 Issue Pages 611-619
Keywords (down)
Abstract Laterality is now known to be an ubiquitous phenomenon among the vertebrates. Particularly, laterality of auditory processing has been demonstrated in a variety of species, especially songbirds and primates. Such a hemispheric specialization has been shown to depend on factors such as sound structure, species specificity and types of stimuli. Much less is known on the possible influence of social familiarity although a few studies suggest such an influence. Here we tested the influence of the degree of familiarity on the laterality of the auditory response in the domestic horse. This species is known for its social system and shows visible reactions to sounds, with one or two ears moving towards a sound source. By comparing such responses to the playback of different conspecific whinnies (group member, neighbor and stranger), we could demonstrate a clear left hemisphere (LH) preference for familiar neighbor calls while no preference was found for group member and stranger calls. Yet, we found an opposite pattern of ear side preference for neighbor versus stranger calls. These results are, to our knowledge, the first to demonstrate auditory laterality in an ungulate species. They open further lines of thought on the influence of the social “value” of calls and the listener's arousal on auditory processing and laterality.

Title How horses (Equus caballus) see the world: humans as significant “objects” Type Journal Article
Year 2009 Publication Animal Cognition Abbreviated Journal Anim. Cogn.
Volume 12 Issue 4 Pages 643-654
Keywords (down)
Abstract Abstract  This study aimed to determine whether horses have a kind of memory of humans (based on previous interactions), leading to a general significance of humans revealed by their reactions to humans in subsequent interactions. Subjects were 59 adult horses used to interact daily with humans. Three types of behavioural tests involving an unknown experimenter evaluated three possibly different memorized types of human–animal interactions (not work-related, using work-related objects, unfamiliar working task). We also performed standardized observations of routine interactions between each horse and its familiar handler (caretaker). To get a broad overview of the horses’ reactions to humans, we recorded both investigative and aggressive behaviours during the tests, representing respectively a “positive†and a “negative†memory of the relationship. Whereas correlations between tests revealed a general perception of humans as either positive or negative, unusual tests, i.e. that are not usually performed, elicited more positive reactions. Moreover, some horses reacted positively to a motionless person in their box, but negatively when this same person approached them, for example for halter fitting. Overall, aggressive reactions were more reliable indicators of the relationship than positive reactions, both between tests and between familiar and unfamiliar humans. Our results also show generalization of the perception of humans. These results support our hypothesis that perception of humans by horses may be based on experience, i.e. repeated interactions. Altogether, our results support the hypothesis that horses can form a memory of humans that impacts their reactions in subsequent interactions.
