Title Relational discrimination learning in horses Type Journal Article
Year 1997 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 54 Issue 4 Pages 267-280
Keywords Horses; Shaping; Complex discrimination; Concept formation; Generalization ability; Training
Abstract (up) This series of studies investigated horses' ability to learn the concept of sameness under several different conditions. Before experimentation began, three horses were shaped to touch individually presented stimuli with their muzzles, and then to make two responses to two matching cards from an array of three. A modified version of the identity matching-to-sample (IMTS) procedure was used to present stimuli in a variety of configural arrangements on a barn wall (Experiment 1 and Experiment 2), and on a flat panel mounted to a barn door (Experiment 3). The task in each experiment was to select the two stimulus cards that were the same (either circles or Xs) and to avoid the nonmatching stimulus card (either a star or a square). In Experiment 1, the mean accuracy rate for selecting the matching alternatives was 74%. The horses' accuracy levels reached a mean level of 83% during Experiment 2, in which they received additional trials and an intermittent secondary reinforcement schedule. In Experiment 3, when the stimuli were moved further apart from each other within arrangements and were presented on a novel background, the mean accuracy rate was 73%. These data demonstrate that horses can learn complex discrimination problems involving the concept of sameness, and that they are able to generalize this learning to a novel stimulus presentation situation. These results also suggest that a relational discrimination test may be useful for assessing horses' learning ability and the level of training appropriate for individual horses.

Title Differences in motor laterality between breeds of performance horse Type Journal Article
Year 2006 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 99 Issue 1-2 Pages 183-190
Keywords Horse; Lateralisation; Laterality; Breed; Training
Abstract (up) This study examined the relationship between motor laterality in horses bred for different types of work and therefore different temperaments. Foreleg preference during grazing was measured in three populations of domestic horse, Thoroughbreds (TB, bred to race at the gallop), Standardbreds (SB, bred for pacing) and Quarter Horses (QH, in this case bred for so-called “cutting work” which involves manoeuvring individual cattle in and out of herds). With a one-sample t-test, TBs showed strong evidence of a left preference in motor laterality (P = 0.000), as did SBs (P = 0.002) but there was no convincing evidence for laterality in QH (P = 0.117). However, the increasing trend in left preference from QH to SBs then TBs was associated with increasing differences between individual horses within a breed. The overall preference (either left or right) increased with age (P = 0.008) and the rate of increase varied with breeds. The presence of a higher proportion of left-foreleg preferent individuals in TBs and SBs compared with QH may indicate that their training or selection (or both) has an effect on motor bias.

Title Discrimination learning based on relative size concepts in horses (Equus caballus) Type Journal Article
Year 2003 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 83 Issue 3 Pages 201-213
Keywords Horse; Concept; Size transposition; Generalization; Learning; Training
Abstract (up) This study explored whether or not horses (Equus caballus) could respond to stimuli using a concept based on relative size. In Experiment 1, after learning to respond to the larger of the two stimuli for six sets of two-dimensional (2D) training exemplars, one horse was tested for size transposition that used novel larger and smaller stimuli as well as three-dimensional (3D) objects (5 two-dimensional sets and 5 three-dimensional sets with large, medium, small, and tiny sizes). The horse correctly chose (significantly above chance) the larger of two stimuli regardless of novelty or dimension or combination. In Experiment 2, two additional horses were tested using a subset of the stimuli from Experiment 1. One horse was required to select the larger stimulus--as in Experiment 1--and the other the smaller stimulus. After learning the task, both horses responded correctly to new stimuli and showed size transposition. These results suggest that at least some horses are capable of solving problems based on relative size concepts. Moreover, they are able to generalize across situations that vary from flat, black shapes to objects of different materials and colors including balls, flower pots, and PVC connectors. These findings support earlier research that showed that horses could categorize certain stimuli, and provide new evidence that they are capable of using some form of concept for problem solving. Understanding that horses have more advanced learning abilities than was previously believed should help improve training methods and management.

Title Length and elasticity of side reins affect rein tension at trot Type Journal Article
Year 2011 Publication The Veterinary Journal Abbreviated Journal
Volume 188 Issue 3 Pages 291-294
Keywords Horse; Equitation; Training; Rein aids
Abstract (up) This study investigated the horse’s contribution to tension in the reins. The experimental hypotheses were that tension in side reins (1) increases biphasically in each trot stride, (2) changes inversely with rein length, and (3) changes with elasticity of the reins. Eight riding horses trotted in hand at consistent speed in a straight line wearing a bit and bridle and three types of side reins (inelastic, stiff elastic, compliant elastic) were evaluated in random order at long, neutral, and short lengths. Strain gauge transducers (240 Hz) measured minimal, maximal and mean rein tension, rate of loading and impulse. The effects of rein type and length were evaluated using ANOVA with Bonferroni post hoc tests. Rein tension oscillated in a regular pattern with a peak during each diagonal stance phase. Within each rein type, minimal, maximal and mean tensions were higher with shorter reins. At neutral or short lengths, minimal tension increased and maximal tension decreased with elasticity of the reins. Short, inelastic reins had the highest maximal tension and rate of loading. Since the tension variables respond differently to rein elasticity at different lengths, it is recommended that a set of variables representing different aspects of rein tension should be reported.

Title Rein contact between horse and handler during specific equitation movements Type Journal Article
Year 2007 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 108 Issue 1-2 Pages 157-169
Keywords Horse; Long-reining; Rein contact; Rein tension; Riding; Training
Abstract (up) To explore the range of tensions used in reins to elicit specific movements from a range of horses, 22 horses of mixed age, sex, breed and training history were long-reined and ridden through a standard course. The reins contained embedded load cells so that tensions used to elicit specific movements could be measured and logged. These movements were categorised into `left turn', `right turn', `going straight' and `halt' and were separated for left and right rein tensions. The data were analysed using two-sample non-parametric Kolmogorov-Smirnoff tests and the differences between categories of horse and equipment were analysed with one-way analysis of variance. The tensions recorded in the reins were greater for long-reining than riding (median 5.76, Q25 3.9, Q75 13.3 N and median 5.29, Q25 9.3, Q75 2.9 N, respectively, P = 0.025), irrespective of whether the horses were ridden with a halter or a bridle or whether the test was completed at a walk or a trot. The tensions did not differ between the left and right reins (P > 0.05) when the horses were being driven or ridden in a straight line, providing evidence that an `even contact' was maintained. The rein tension required for going straight was less than for any other responses, showing that a lighter contact on the reins can be maintained between the application of specific stimuli. The rein tension required to elicit the halt response was greater than for any other response (P < 0.001). The rein tensions required to complete the course did not differ with the use of bridle versus the halter (P > 0.05). Clearly, a range of rein tensions is required for horses to elicit specific responses. In the interests of horse welfare and avoidance of habituation, those involved in equitation need to become aware of the tensions used in training horses and seek to keep them to a minimum. When rein tension can be measured objectively, this process can be easily implemented and monitored.

Title Behavioral, demographic and management influences on equine responses to negative reinforcement Type Journal Article
Year 2018 Publication Journal of Veterinary Behavior Abbreviated Journal
Volume Issue Pages
Keywords Learning; horse management; training; temperament; negative reinforcement
Abstract (up) Understanding the factors that influence horse learning is critical to ensure horse welfare and rider safety. In this study, data were obtained from horses (n=96) training to step backwards through a corridor in response to bit pressure. Following training, learning ability was determined by the latency to step backwards through the corridor when handled on the left and right reins. Additionally, horse owners were questioned about each horse's management, training, behavior and signalment (such as horse breed, age and sex). Factors from these four broad domains were examined using a multiple logistic regression (MLR) model, following an Information Theoretic approach, for associations between horses' behavioral attributes and their ability to learn the task. The MLR also included estimates of the rider's ability and experience as well as owner's perceptions of their horse's trainability and temperament. Results revealed several variables including explanatory variables that correlated significantly with rate of learning. Horses were faster at backing, a behavioral trait, when handled on the right (t = 3.65, df = 94, P < 0.001) than the left side. Thoroughbred horses were slower at completing the tests than other breeds of horses when handled on the left side (LM, F1,48=4.5, P=0.04) and right side (LM, F1,45=6.0, P=0.02). Those in regular work, a training factor, did not learn faster than their unworked counterparts on the right rein but completed the task faster on the left rein (F1,44=5.47, P=0.02). This may reflect differences in laterality and habituation effects. In contrast, more anxious horses were faster at completing the test when handled from the right (Spearman, r=-0.22, P=0.04). It is possible that these horses have an increased arousal level when interacting with handlers, resulting in more engagement with the lesson, accounting for the improved performance results. The findings of this study will help clarify how horse behavior, training and management may influence learning and how their application may optimize learning outcomes. Future equine behavior assessment and research questionnaires should include items that assess these qualities.

Title Unwanted oral investigative behaviour in horses: A note on the relationship between mugging behaviour, hand-feeding titbits and clicker training Type Journal Article
Year 2010 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 127 Issue 3-4 Pages 104-107
Keywords Equine; Horse; Titbits; Food rewards; Clicker training; Mugging behaviour
Abstract (up) Unwanted oral investigative in horses has been anecdotally attributed to the practice of hand-feeding. Fears over such behaviour developing as a consequence of using food rewards, for example in clicker training, have been implicated as a common reason for not employing food-based positive reinforcement training techniques. This study used data generated as part of a larger research project, and explored associations between five common oral investigative behaviours and the practices of hand-feeding and clicker training. Data were from a convenience sample of UK leisure horse owners using two self-administered Internet surveys. Ninety-one percent of respondents reported giving their horse food by hand and this practice was significantly associated with three of the five oral investigative behaviours, licking hands (P = 0.006), gently searching clothing (P < 0.001) and roughly searching clothing (P = 0.003). Nipping hands and biting clothes were not associated with hand-feeding, suggesting that risk factors for these behaviours originate outside of this practice. Clicker training techniques were employed by 14% of respondents and their use was not associated with the incidence of any of the five oral investigative behaviours. These findings suggest that horse owners should not be deterred from using food-based positive reinforcement techniques with their horses, as fears that this practice will result in unwanted oral investigative behaviours from their horses appear unfounded.

Title Does attention make the difference? Horses' response to human stimulus after 2 different training strategies Type Journal Article
Year 2011 Publication Journal of Veterinary Behavior: Clinical Applications and Research Abbreviated Journal J Vet Behav Clin Appl Res
Volume 6 Issue 1 Pages 31-38
Keywords attention; exploration; horse; human stimulus; training
Abstract (up) We hypothesized that in an open environment, horses cope with a series of challenges in

their interactions with human beings. If the horse is not physically constrained and is free to move

in a small enclosure, it has additional options regarding its behavioral response to the trainer. The

aim of our study was to evaluate the influence of 2 different training strategies on the horse’s behavioral

response to human stimuli. In all, 12 female ponies were randomly divided into the following 2

groups: group A, wherein horses were trained in a small enclosure (where indicators of the level of

attention and behavioral response were used to modulate the training pace and the horse’s control over

its response to the stimuli provided by the trainer) and group B, wherein horses were trained in a closed

environment (in which the trainer’s actions left no room for any behavioral response except for the one

that was requested). Horses’ behavior toward the human subject and their heart rate during 2 standardized

behavioral tests were used to compare the responses of the 2 groups. Results indicated that the

horses in group A appeared to associate human actions with a positive experience, as highlighted by

the greater degree of explorative behavior toward human beings shown by these horses during the tests.

The experience of the horses during training may have resulted in different evaluations of the person, as

a consequence of the human’s actions during training; therefore, it seems that horses evaluate human

beings on daily relationship experiences.

Title Motor and sensory laterality in thoroughbred horses Type Journal Article
Year 2005 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 92 Issue 4 Pages 337-352
Keywords Horse; Lateralisation; Training; Olfaction; Forelimb preference
Abstract (up) We investigated lateralisation in horses because it is likely to be important in training and athletic performance. Thoroughbred horses (n = 106) were observed every 60 s for 2 h, when they were at pasture, and the position of the forelimbs in relation to one another was recorded. There was a population bias skewed to standing with the left forelimb advanced over the right (i.e. directional lateralisation). Using the first 50 observations, the distribution of preferences was 43 significantly left, 10 significantly right with 53 being non-significant (i.e. ambidextextrous). The strength of motor bias increased with age, suggesting maturation or an influence of training. The horses were also presented with an olfactory stimulus (stallion faeces) to score the tendency to use one nostril rather than the other. A significant preference to use the right nostril first was shown in horses under 4 years of age (n = 61) but not in older horses. Of the 157 horses tested for nostril bias, 76 had been assessed for motor bias and so were used for analysis of the relationship between laterality in the two modalities. There was no significant relationship between direction of foreleg motor bias and first nostril used, total number of inhalations or laterality index of nostril use. The absence of a correlation between laterality of nostril use and motor bias indicates that lateralisation of the equine brain occurs on at least two levels of neural organisation--sensory and motor--a finding that is consistent with other examples of lateralisation in species that have been examined in more detail.
