Abstract

Spatial abilities of Wild Chimpanzees Pan troglodytes verus: Malgré la multiplicité des études démontrant le comportement fascinant des animaux dans leur milieu naturel, quelques domaines de recherches demeurent difficiles à aborder. Ainsi, l’étude de certains aspects cognitifs nécessite un certain contrôle sur l’environnement afin de dissocier les influences écologiques et sociales de l’implication cognitive ; par exemple la cognition spatiale incluant la mémoire spatiale, les mécanismes d’orientation spatiale, ainsi que leur implication dans la navigation, tel que par la planification. L’étude de la cognition spatiale des chimpanzés sauvages s’est déroulée dans le Parc national de Taï, une forêt tropicale dense où les ressources potentielles sont abondantes et réparties sur un territoire de 25 km², avec une visibilité d’environ 30 mètres. De plus, les chimpanzés vivent dans une société du type fission-fusion, impliquant de multiples relations sociales. Toutefois, l’enregistrement précis de la position et des activités des chimpanzés, ainsi qu’une carte botanique précise, nous a permis de dissocier les effets écologiques, sociaux et cognitifs afin de mieux comprendre les relations entre ces différents facteurs. Par cette étude, nous montrons que les chimpanzés ont développé un mécanisme permettant une navigation précise grâce à une carte Euclidienne contenant des informations sur la direction et la distances vers des ressources connues. Ce mécanisme est extrêmement adapté et efficace par la connaissance précise de la localisation de milliers de ressources dans leur habitat. Ces capacités permettent d’augmenter leur efficacité en sélectionnant les ressources les plus productives, en les planifiant à l’avance et, de manière plus avancée, en planifiant le parcours le plus court à travers ces différentes ressources durant la journée lorsque la pression sociale requière une meilleure précision dans le choix des ressources. Ces découvertes illustrent d’abord les capacités extraordinaires des chimpanzés, et deuxièmement que les aspects cognitifs peuvent être expliqués dans le milieu naturel des animaux.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
