Title (up) Animal behavior and animal welfare Type Journal Article
Year 1991 Publication Journal of the American Veterinary Medical Association Abbreviated Journal J Am Vet Med Assoc
Volume 198 Issue 8 Pages 1355-1360
Keywords *Animal Welfare; Animals; *Behavior, Animal; Cats/*psychology; Hoof and Claw/surgery; Horses/*psychology; Housing, Animal
Abstract 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 (up) Applying learning theory to the management of the horse: the difference between getting it right and getting it wrong Type Journal Article
Year 1998 Publication Equine veterinary journal. Supplement Abbreviated Journal Equine Vet J Suppl
Volume Issue 27 Pages 44-48
Keywords Animals; *Behavior, Animal; Horses/*psychology; *Learning; Reinforcement (Psychology)
Abstract Horses constantly modify their behaviour as a result of experience. This involves the creation of an association between events or stimuli. The influence of people on the modification and generation of certain behaviour patterns extends beyond the intentional training of the horse. The impact of any action depends on how it is perceived by the horse, rather than the motive of the handler. Negative and positive reinforcement increase the probability of specific behaviours recurring i.e. strengthen the association between events, whereas punishment reduces the probable recurrence of a behaviour without providing specific information about the desired alternative. In this paper the term 'punishers' is used to refer to the physical aids, such as a whip or crop, which may be used to bring about the process of punishment. However, if their application ceases when a specific behaviour occurs they may negatively reinforce that action. Intended 'punishers' may also be rewarding (e.g. for attention seeking behaviour). Therefore, contingency factors (which define the relationship between stimuli, such as the level of reinforcement), contiguity factors (which describe the proximity of events in space or time) and choice of reinforcing stimuli are critical in determining the rate of learning. The many problems associated with the application of punishment in practice lead to confusion by both horse and handler and, possibly, abuse of the former. Most behaviour problems relate to handling and management of the horse and can be avoided or treated with a proper analysis of the factors influencing the behaviour.

Title (up) Color vision in horses (Equus caballus): deficiencies identified using a pseudoisochromatic plate test Type Journal Article
Year 2007 Publication Journal of Comparative Psychology Abbreviated Journal J. Comp. Psychol.
Volume 121 Issue 1 Pages 65-72
Keywords Animals; Appetitive Behavior; *Color Perception; Color Perception Tests/veterinary; *Discrimination Learning; Female; Horses/*psychology; Male; Sensitivity and Specificity
Abstract In the past, equine color vision was tested with stimuli composed either of painted cards or photographic slides or through physiological testing using electroretinogram flicker photometry. Some studies produced similar results, but others did not, demonstrating that there was not yet a definitive answer regarding color vision in horses (Equus caballus). In this study, a pseudoisochromatic plate test--which is highly effective in testing color vision both in small children and in adult humans--was used for the first time on a nonhuman animal. Stimuli consisted of different colored dotted circles set against backgrounds of varying dots. The coloration of the circles corresponded to the visual capabilities of different types of color deficiencies (anomalous trichromacy and dichromacy). Four horses were tested on a 2-choice discrimination task. All horses successfully reached criterion for gray circles and demonstration circles. None of the horses were able to discriminate the protan-deutan plate or the individual protan or deutan plates. However, all were able to discriminate the tritan plate. The results suggest that horses are dichromats with color vision capabilities similar to those of humans with red-green color deficiencies.

Title (up) 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 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 (up) 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 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 (up) 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 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.
