Sablé-Meyer, M., Fagot, J. & Dehaene, S. (2026). Comparing Geometric Shape Representations in Humans and Baboons: A Language of Thought Perspective. Topics in Cognitive Science 00 (2026), 1–27, DOI: 10.1111/tops.70038 In various cultures, across history and at many different spatial scales, humans produce a rich variety of geometric shapes. Recent work has put forward a […]
Reboul A, Claidière N, Dautriche I, Fagot J (2025) Testing semantic compositionality in baboons (Papio papio) through relearning and generalization. PLoS One 20(11): e0334726. This study investigates whether baboons are capable of semantic compositionality, specifically, whether they can apply compositional rules to new situations (generalization). In language, semantic compositionality is linked to productivity, the generalization […]
Floor Meewis, Joël Fagot, Nicolas Claidière, Isabelle Dautriche. Agent Preference in Chasing Interactions in Guinea Baboons ( Papio papio ): Uncovering the Roots of Subject–Object Order in Language. Psychological Science, 2025, 36 (6), pp.465-477. ff10.1177/09567976251344581ff. ffhal-05169637f Languages tend to describe “who is doing what to whom” by placing subjects before objects. This may reflect […]
Ciccione L, Dighiero-Brecht T, Claidière N, Fagot J, Dehaene S. Can non-human primates extract the linear trend from a noisy scatterplot? iScience. 2024 Dec 20;28(1):111661. doi: 10.1016/j.isci.2024.111661. PMID: 39868034; PMCID: PMC11761879. (open access) Recent studies showed that humans, regardless of age, education, and culture, can extract the linear trend of a noisy scatterplot. Although […]
Gullstrand J, Claidière N, Fagot J (2024) Cognitive flexibility and sociality in Guinea baboons (Papio papio). PLoS ONE 19(12): e0308778 (open access) Cognitive flexibility is an executive function playing an important role in problem solving and the adaptation to contextual changes. While most studies investigated the contribution of cognitive flexibility to solve problems in […]
Tosatto, L., Fagot, J., Nemeth, J. & Rey,A. (2024). Chunking as a Function of Sequence Length. Animal Cognition, 28(1):2 Abstract – Chunking mechanisms are central to several cognitive processes. During the acquisition of visuo-motor sequences, it is commonly reported that these sequences are segmented into chunks leading to more fluid, rapid, and accurate performances. […]
Margiotoudi, K., Fagot, J., Meguerditchian, A. & Dautriche, I. (2024). Humans (Homo sapiens) but not baboons (Papio papio) demonstrate crossmodal pitch-luminance correspondence. American Journal of Primatology, 86(5). Humans spontaneously and consistently map information coming from different sensory modalities. Surprisingly, the phylogenetic origin of such cross-modal correspondences has been under-investigated. A notable exception is the […]
Laure Tosatto, Joël Fagot et Arnaud Rey, « Sequence Learning and Chunk Stability in Guinea Baboons (Papio papio) », Revue de primatologie [En ligne], 14 | 2023, mis en ligne le 22 décembre 2023 Abstract – Les mécanismes de chunking, processus par lesquels plusieurs items sont regroupés pour former une unité fonctionnelle, sont centraux dans […]
Ordonez Magro, L., Fagot, J., Grainger, J. et al. On the role of interference in sequence learning in Guinea baboons (Papio papio). Learn Behav 51, 201–212 (2023). https://doi.org/10.3758/s13420-022-00537-13 Abstract – It is well established that decay and interference are the two main causes of forgetting. In the present study, we specifically focus on the impact of interference on memory […]
Yeaton, J., Tosatto, L., Fagot, J. et al. Simple questions on simple associations: regularity extraction in non-human primates. Learn Behav 51, 392–401 (2023). https://doi.org/10.3758/s13420-023-00579-z Abstract – When human and non-human animals learn sequences, they manage to implicitly extract statistical regularities through associative learning mechanisms. In two experiments conducted with a non-human primate species (Guinea […]
Tosatto L, Fagot J, Rey A. The dynamics of chunking in humans (Homo sapiens) and Guinea baboons (Papio papio). J Comp Psychol. 2023 Aug;137(3):191-199. doi: 10.1037/com0000336. Epub 2023 Jun 1. PMID: 37261734. Abstract – Chunking is an important cognitive process allowing the compression of information in short-term memory. The aim of this study is […]
Bonafos, G., Pudlo, P., Freyermuth, J. M., Legou, T., Fagot, J., Tronçon, S., & Rey, A. (2023). Detecting human and non-human vocal productions in large scale audio recordings. arXiv preprint arXiv:2302.07640. Abstract – We propose an automatic data processing pipeline to extract vocal productions from large-scale natural audio recordings and classify these vocal productions. The […]
Formaux, A., Sperber, D., Fagot, J., & Claidière, N. (2023) Guinea baboons are strategic cooperators. Science Advances, 9(43), eadi5282. doi:10.1126/sciadv.adi528 Humans are strategic cooperators; we make decisions on the basis of costs and benefits to maintain high levels of cooperation, and this is thought to have played a key role in human evolution. In […]
Gullstrand, J., Claidière, N., & Fagot, J. (2022). Age effect in expert cognitive flexibility in Guinea baboons (Papio papio). Behavioural Brain Research, 434, 114043. doi:https://doi.org/10.1016/j.bbr.2022.114043 Abstract: Cognitive flexibility in non-human primates is traditionally measured with the conceptual set shifting task (CSST). In our laboratory, Guinea baboons (N = 24) were continuously tested with […]

Learn Behav (2022). https://doi.org/10.3758/s13420-022-00522-8.3 Abstract – While humans exposed to a sequential stimulus pairing A-B are commonly assumed to form a bidirectional mental relation between A and B, evidence that non-human animals can do so is limited. Careful […]
