Horses that display stereotypic (repetitive, idiosyncratic and invariant response patterns) behavior have been shown to have differences in central nervous system physiology. Specifically, they have been found to have sensitized striatal dopaminergic pathways. Pharmacological sensitization of the striatum has been shown to lead to an accelerated shift from planned behaviour (response-outcome) to habitual responding (stimulus-response), in the context of US devaluation and place-response paradigms. Therefore, theoretically, endogenously produced sensitization would be expected to lead to a similar accelerated shift. In the present study, matched pairs of stereotypic and non-stereotypic horses were trained to locate food in a standard cross-maze. After training, subjects were challenged with a probe trial, in which they were placed in an immediately adjacent mirror image maze. Differences between the groups were found, and results are discussed in the context of the equine stereotypy phenotype.
