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 […]
Chartier, T.F., Fagot, J. Simultaneous learning of directional and non-directional stimulus relations in baboons (Papio papio). 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 […]
Chartier, T. & Fagot, J.(2022,). Associative symmetry: a divide between humans and nonhumans? Trends in Cognitive Sciences. https://doi.org/10.1016/j.tics.2022.01.009 Abstract – Anthropocentrism can bias scientific conclusions. As a case study, we challenge the 40-year-old associative symmetry dogma, supposed to cognitively set apart humans from other species. Out of 37 human studies surveyed, only three truly demonstrate […]
Dautriche, I., Buccola, B., Berthet, M. et al. Evidence for compositionality in baboons (Papio papio) through the test case of negation. Sci Rep 12, 19181 (2022). https://doi.org/10.1038/s41598-022-21143-1 Abstract – Can non-human animals combine abstract representations much like humans do with language? In particular, can they entertain a compositional representation such as ‘not blue’? Across […]
Rey A, Fagot J, Mathy F, Lazartigues L, Tosatto L, Bonafos G, Freyermuth JM, Lavigne F. Learning Higher-Order Transitional Probabilities in Nonhuman Primates. Cogn Sci. 2022 Apr;46(4):e13121. doi: 10.1111/cogs.13121. PMID: 35363923. Abstract – The extraction of cooccurrences between two events, A and B, is a central learning mechanism shared by all species capable of […]
Reboul, A., Mascaro, O., Claidière, N., & Fagot, J. (2022). Are monkeys sensitive to informativeness: An experimental study with baboons (Papio papio). Plos one, 17(7), e0270502. Abstract – Informativeness (defined as reduction of uncertainty) is central in human communication. In the present study, we investigate baboons’ sensitivity to informativeness by manipulating the informativity of a […]
Formaux, A., O’Sullivan, E., Fagot, J., & Claidière, N. (2022). Understanding imitation in Papio papio: the role of experience and the presence of a conspecific demonstrator. Cognitive Science, 46(3), e13117 Abstract – What factors affect imitation performance? Varying theories of imitation stress the role of experience, but few studies have explicitly tested its role […]
Fatima-ezzahra Ennaji, Pascal Belin, Joël Fagot. Categorization of vocal and nonvocal stimuli in Guinea baboons (Papio papio). American Journal of Primatology, 2022, ff10.1002/ajp.23387ff. ffhal03661496f Abstract – Categorization of vocal sounds apart from other sounds is one of the key abilities in human voice processing, but whether this ability is present in other animals, particularly […]
Tosatto, L., Fagot, J., Nemeth, D., & Rey, A. (2022). The evolution of chunks in sequence learning. Cognitive Science, 46(4), e13124. Abstract – Chunking mechanisms are central to several cognitive processes and notably to the acquisition of visuo‐motor sequences. Individuals segment sequences into chunks of items to perform visuo‐motor tasks more fluidly, rapidly, and accurately. […]
Sablé-Meyer, M., Fagot, J., Caparos, S., van Kerkoerle, , T., Amalric, M. & Dehaene, S. (2021). Sensitivity to geometric shape regularity in humans and baboons: A putative signature of human singularity. PNAS April 20, 2021 118 (16) e20231231183 Abstract – Determining the cognitive differences between human and nonhuman primates is a central goal of […]
Formaux, A., Fagot, J. & Claidière, N. (2021). “The experimental emergence of convention in a non-human primate”. Phil. Trans. R. Soc. B 377: 20200310. https://doi.org/10.1098/rstb.2020.03103 Abstract – Conventions form an essential part of human social and cultural behaviour and may also be important to other animal societies. Yet, despite the wealth of evidence that […]
