Résumé : | Determinants of yawning are still uncertain. As yawning seems to be trigged by stress an emotional contexts, we investigated specific correlates of yawning and seterotypic behaviours inhorses. Study 1 investigated correlations in time between yamning and stereotypic behaviour in stereotypic horses from the same facility : study 2, involving riding school horses, investigated the cooccurrence of yawning and stereotypic behaviour at the individual level and in response to envrionmental factors (feeding time). Results showed that (1) stereotypic horses yawned more than the nonstereotypic horses, (2) yamning increased at the same time periods as stereotypic behaviours did, and (3) yamning frequency was positively correlated with stereotypic behaviour frequencies (study 1). Different hypotheses are discussed : direct/indirect causal relationship and other factors susceptible to trigger both yawning and stereotypies. This study, underlining for the first time a cooccurrence oy yawning and stereotypic behaviour, opens a promising line of investigation of this puzzling behaviour. |
