Sujet de thèse : Exploration du concept d’agentivité chez la vache dans un contexte d’amélioration du bien-être.

Encadrants : Léa LANSADE et Ludovic CALANDREAU

Les nouvelles approches du bien-être animal incluent désormais la notion d’état mental positif. Ainsi, plutôt que de simplement chercher à limiter les évènements négatifs (stress, douleur), on cherche à induire des situations génératrices d’états affectifs positifs, en s’inscrivant dans une démarche de « positive welfare ». Une des théories émergentes du positive welfare est celle proposée par Spinka et repose sur la notion d’agentivité. Selon cette théorie, le fait pour les animaux d’avoir un contrôle sur leur environnement, d’être plus à même de prédire ce qui leur arrive et de faire des choix éclairés serait à même de susciter un état mental positif. Se pose alors la question du niveau d’agentivité dont sont capables les animaux : dans quelle mesure l’animal perçoit et comprend son environnement pour faire des choix qui pourront lui être bénéfiques à court mais aussi à plus long terme. Le concept proposé par Spinka repose sur quatre niveaux d’agentivité de complexité croissante. Cela va d’un niveau basique de type stimulus réponse, jusqu’à un niveau qui requière des compétences cognitives complexes, nécessitant pour l’animal de faire des choix qui auront des bénéfices à long terme, à travers la planification prospective et la réflexion autobiographique. L’objectif de ce projet sera de comprendre quel niveau d’agentivité la vache est capable d’atteindre, et de proposer des enrichissements de son milieu de vie qui soient en adéquation.

  • [hal-05789729] Cows visually discriminate and cross-modally recognise familiar and unfamiliar human faces in videos

    Social recognition has been studied and demonstrated in many species. In domesticated species, the long evolutionary history shared with humans has led to investigations into their cognitive abilities towards humans, particularly regarding discrimination and recognition of humans. The present study investigated whether cows are capable of visual discrimination and cross-modal recognition of familiar and unfamiliar humans. Thirty-two cows were exposed to two tests: a visual preference test, during which two silent videos were shown simultaneously – each displaying either a familiar or an unfamiliar human face – and a cross-modal test, during which the videos were accompanied by either a congruent or incongruent voice. During the visual preference test, cows looked significantly longer at the video showing the unfamiliar person (p = 0.028). In the cross-modal test, they looked significantly longer at the video that was congruent with the voice being played (p = 0.014). These two results show that cows are able to discriminate between familiar and unfamiliar individuals and form cross-modal representations of these people. Based on these results, future research should explore whether cows can adjust their behaviour depending on the person they are interacting with – a capacity that may reflect their agency in human-animal relationships.

  • [hal-05789521] Cows react to human emotions displayed in videos and use this information to guide subsequent interaction choices

    The ability to perceive and interpret emotions from others provides clear evolutionary advantages for social animals. Domestic animals live in close contact with humans, making human emotional cues particularly relevant for them. Understanding how these animals recognise, memorise, and respond to human emotional signals is therefore crucial to investigating their cognitive capacities and their active role in interspecific social interactions. Thus, this study investigates whether cows can discriminate between human expressions and use this information to guide their behaviour in a subsequent choice test. Thirty-nine cows were shown two 30-second videos: one of an experimenter expressing joy and another expressing anger through facial and vocal cues. Afterward, both experimenters simultaneously presented themselves to the cows in a choice test. During video exposure, cows looked longer at the anger video and showed a left-eye bias, suggesting right-hemisphere processing of negatively valenced stimuli. They also displayed more behaviours indicative of a negative perception. In the subsequent choice test, cows spent significantly more time close to the experimenter who had previously expressed joy. These results demonstrate that cows can discriminate and remember human emotional expressions and use this information to guide their choices in future social interactions. This highlights their role as active participants rather than passive observers in interspecific relationships, and provides insight into contexts where such abilities may be expressed, with potential implications for enhancing human-animal relationships and welfare.
