Impaired instrumental choice in crib-biting horses (Equus caballus)

Impaired instrumental choice in crib-biting horses (Equus caballus)
Horses displaying an oral stereotypy were tested on an instrumental choice paradigm to examine differences in learning from non-stereotypic counterparts. The paradigm was specifically applied in order to examine learning that requires maintenance of response-outcome judgements. The stereotypic horses were found not to choose a more immediate reinforcer over three learning sessions. This suggests an initial behavioural correlate for dorsomedial striatum dysregulation in the stereotypy phenotype.

Abstract

Horses displaying an oral stereotypy were tested on an instrumental choice paradigm to examine differences in learning from non-stereotypic counterparts. The paradigm was specifically applied in order to examine learning that requires maintenance of response-outcome judgements. The stereotypic horses were found not to choose a more immediate reinforcer over three learning sessions. This suggests an initial behavioural correlate for dorsomedial striatum dysregulation in the stereotypy phenotype.
