  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 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 (down) 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 Stimulus generalization, discrimination learning, and peak shift in horses Type Journal Article
  Year 1991 Publication Journal of the experimental analysis of behavior Abbreviated Journal J Exp Anal Behav  
  Volume 56 Issue 1 Pages 97-104  
  Keywords Animals; *Appetitive Behavior; Attention; *Conditioning, Operant; *Discrimination Learning; Female; *Generalization, Stimulus; Horses/*psychology; Male; *Pattern Recognition, Visual; Size Perception  
  Abstract (down) Using horses, we investigated three aspects of the stimulus control of lever-pressing behavior: stimulus generalization, discrimination learning, and peak shift. Nine solid black circles, ranging in size from 0.5 in. to 4.5 in. (1.3 cm to 11.4 cm) served as stimuli. Each horse was shaped, using successive approximations, to press a rat lever with its lip in the presence of a positive stimulus, the 2.5-in. (6.4-cm) circle. Shaping proceeded quickly and was comparable to that of other laboratory organisms. After responding was maintained on a variable-interval 30-s schedule, stimulus generalization gradients were collected from 2 horses prior to discrimination training. During discrimination training, grain followed lever presses in the presence of a positive stimulus (a 2.5-in circle) and never followed lever presses in the presence of a negative stimulus (a 1.5-in. [3.8-cm] circle). Three horses met a criterion of zero responses to the negative stimulus in fewer than 15 sessions. Horses given stimulus generalization testing prior to discrimination training produced symmetrical gradients; horses given discrimination training prior to generalization testing produced asymmetrical gradients. The peak of these gradients shifted away from the negative stimulus. These results are consistent with discrimination, stimulus generalization, and peak-shift phenomena observed in other organisms.

  Title Comparative learning theory and its application in the training of horses Type Journal Article
  Year 1998 Publication Equine veterinary journal. Supplement Abbreviated Journal Equine Vet J Suppl  
  Volume Issue 27 Pages 39-43  
  Keywords Animals; *Behavior, Animal; Conditioning (Psychology); Horses/*psychology; *Learning; Reinforcement (Psychology)  
  Abstract (down) Training can best be explained as a process that occurs through stimulus-response-reinforcement chains, whereby animals are conditioned to associate cues in their environment, with specific behavioural responses and their rewarding consequences. Research into learning in horses has concentrated on their powers of discrimination and on primary positive reinforcement schedules, where the correct response is paired with a desirable consequence such as food. In contrast, a number of other learning processes that are used in training have been widely studied in other species, but have received little scientific investigation in the horse. These include: negative reinforcement, where performance of the correct response is followed by removal of, or decrease in, intensity of a unpleasant stimulus; punishment, where an incorrect response is paired with an undesirable consequence, but without consistent prior warning; secondary conditioning, where a natural primary reinforcer such as food is closely associated with an arbitrary secondary reinforcer such as vocal praise; and variable or partial conditioning, where once the correct response has been learnt, reinforcement is presented according to an intermittent schedule to increase resistance to extinction outside of training.

  Title Don't fence me in: managing psychological well being for elite performance horses Type Journal Article
  Year 2007 Publication Journal of Applied Animal Welfare Science : JAAWS Abbreviated Journal J. Appl. Anim. Welf. Sci.  
  Volume 10 Issue 4 Pages 309-329  
  Keywords *Animal Husbandry; Animal Welfare; Animals; *Behavior, Animal; Horses/*psychology; *Physical Conditioning, Animal; *Stereotyped Behavior  
  Abstract (down) This article posits that stereotypical behavior patterns and the overall psychological well being of today's performance horse could be substantially enhanced with care that acknowledges the relationship between domesticated horses and their forerunners. Feral horses typically roam in stable, social groups over large grazing territories, spending 16-20 hr per day foraging on mid- to poor-quality roughage. In contrast, today's elite show horses live in relatively small stalls, eat a limited-but rich-diet at specific feedings, and typically live in social isolation. Although the horse has been domesticated for more than 6000 years, there has been no selection for an equid who no longer requires an outlet for these natural behaviors. Using equine stereotypies as a welfare indicator, this researcher proposes that the psychological well being of today's performance horse is compromised. Furthermore, the article illustrates how minimal management changes can enhance horses' well being while still remaining compatible with the requirements of the sport-horse industry. The article discusses conclusions in terms of Fraser, Weary, Pajor, and Milligan's “integrative welfare model” (1997).

  Title Dynamic averaging and foraging decisions in horses (Equus callabus) Type Journal Article
  Year 2005 Publication Journal of Comparative psychology Abbreviated Journal J. Comp. Psychol.  
  Volume 119 Issue 3 Pages 352-358  
  Keywords Animals; *Decision Making; *Feeding Behavior; Female; Horses/*psychology; Male; *Memory, Short-Term; Motivation; Orientation; *Social Environment  
  Abstract (down) The variability of most environments taxes foraging decisions by increasing the uncertainty of the information available. One solution to the problem is to use dynamic averaging, as do some granivores and carnivores. Arguably, the same strategy could be useful for grazing herbivores, even though their food renews and is more homogeneously distributed. Horses (Equus callabus) were given choices between variable patches after short or long delays. When patch information was current, horses returned to the patch that was recently best, whereas those without current information matched choices to the long-term average values of the patches. These results demonstrate that a grazing species uses dynamic averaging and indicate that, like granivores and carnivores, they can use temporal weighting to optimize foraging decisions.

  Title Animal behavior and animal welfare Type Journal Article

  Volume 198 Issue 8 Pages 1355-1360  
  Keywords *Animal Welfare; Animals; *Behavior, Animal; Cats/*psychology; Hoof and Claw/surgery; Horses/*psychology; Housing, Animal  
  Abstract (down) The value of behavioral techniques in assessing animal welfare, and in particular assessing the psychological well being of animals, is reviewed. Using cats and horses as examples, 3 behavioral methods are presented: (1) comparison of behavior patterns and time budgets; (2) choice tests; and (3) operant conditioning. The behaviors of intact and declawed cats were compared in order to determine if declawing led to behavioral problems or to a change in personality. Apparently it did not. The behavior of free ranging horses was compared with that of stabled horses. Using two-choice preference tests, the preference of horses for visual contact with other horses and the preference for bedding were determined. Horses show no significant preference for locations from which they can make visual contact with other horses, but they do prefer bedding, especially when lying down. Horses will perform an operant response in order to obtain light in a darkened barn or heat in an outside shed. These same techniques can be used to answer a variety of questions about an animal's motivation for a particular attribute of its environment.

  Title Loading the problem loader: the effects of target training and shaping on trailer-loading behavior of horses Type Journal Article
  Year 2001 Publication Journal of Applied Behavior Analysis Abbreviated Journal J Appl Behav Anal  
  Volume 34 Issue 4 Pages 409-423  
  Keywords Animals; *Conditioning, Operant; *Escape Reaction; Female; Horses/*psychology; Reinforcement (Psychology); *Transportation  
  Abstract (down) The purpose of this study was to develop an effective method for trailer loading horses based on principles of positive reinforcement. Target training and shaping were used to teach trailer-loading behavior to 5 quarter horse mares in a natural setting. All 5 had been trailer loaded before through the use of aversive stimulation. Successive approximations to loading and inappropriate behaviors were the dependent variables. After training a horse to approach a target, the target was moved to various locations inside the trailer. Horses started training on the left side of a two-horse trailer. After a horse was loading on the left side, she was moved to the right side, then to loading half on the right and half on the left. A limited-hold procedure and the presence of a companion horse seemed to facilitate training for 1 horse. Inappropriate behaviors fell to zero immediately after target training, and all the horses successfully completed the shaping sequence. Finally, these effects were observed to generalize to novel conditions (a different trainer and a different trailer).

  Title Personality and individual differences in the horse, their significance, use and measurement Type Journal Article
  Year 1998 Publication Equine Veterinary Journal. Supplement Abbreviated Journal Equine Vet J Suppl  
  Volume Issue 27 Pages 10-13  
  Keywords Animals; *Behavior, Animal; Horses/*psychology; Personality  
  Abstract (down) 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 in which specific behavioural tendencies are sought. Individual differences in behaviour also reflect the range of subjective feelings experienced by animals and therefore need to be understood by those concerned with animal welfare. Psychometric techniques concerned with the assessment of personality may provide a suitable basis for scientific study in this field. Potentially methodologies include: behavioural tests, objective behaviour measures or the quantification of reports from those familiar with the subjects. The assessment of the validity and reliability of the variables measured in these tests is an integral part of their development. Interobserver correlation in an experiment based on the subjective rating of 20 horses with respect to 14 familiar terms used to describe horse personality was generally low. This suggests that, with the exception of the terms 'flighty' and 'sharp', the empirical terminology commonly used to describe horse personality is unreliable.

  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 *Affect; Animals; Behavior, Animal/*physiology; *Environment; Female; Horses/*psychology; Learning; Male; Memory/physiology  
  Abstract (down) 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 Trailer loading stress in horses: behavioral and physiological effects of nonaversive training (TTEAM) Type Journal Article
  Year 2003 Publication Journal of Applied Animal Welfare Science : JAAWS Abbreviated Journal J Appl Anim Welf Sci  
  Volume 6 Issue 4 Pages 263-274  
  Keywords Animals; *Conditioning, Operant; *Escape Reaction; Female; Heart Rate; Horses/*psychology; Hydrocortisone/metabolism; Male; Saliva/metabolism; Stress/metabolism/prevention & control/*veterinary; *Transportation  
  Abstract (down) Resistance in the horse to trailer loading is a common source of stress and injury to horses and their handlers. The objective of this study was to determine whether nonaversive training based on the Tellington-Touch Equine Awareness Method (TTEAM; Tellington-Jones &Bruns, 1988) would decrease loading time and reduce stress during loading for horses with a history of reluctance to load. Ten horses described by their owners as “problem loaders” were subjected to pretraining and posttraining assessments of loading. Each assessment involved two 7-min loading attempts during which heart rate and saliva cortisol were measured. The training consisted of six 30-min sessions over a 2-week period during which the horse and owner participated in basic leading exercises with obstacles simulating aspects of trailering. Assessment showed heart rate and saliva cortisol increased significantly during loading as compared to baseline (p <.001 and p <.05, respectively). Reassessment after training showed a decrease in loading time (p <.02), reduced heart rate during loading (p <.002), and reduced saliva cortisol as compared to pretraining assessments. Seven “good loaders” also were subject to loading assessment for physiological comparison. Increases in heart rate during loading were significantly higher in the good loaders (p <.001). Nonaversive training simulating aspects of loading may effectively reduce loading time and stress during loading for horses with a history of resistance to trailer loading.
