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 […]
Claidière, N., Gullstrand, J., Latouche, A. & Fagot, J. (2021). Using Automated Learning Devices for Monkeys (ALDM) to study social networks. Behaviour Research Methods, (2017) 49:24–34 doi:https://doi.org/10.3758/s13428-015-0686-9 Abstract: Social network analysis has become a prominent tool to study animal social life, and there is an increasing need to develop new systems to collect social […]
Gullstrand, J., Claidière, N. & Fagot, J. Computerized assessment of dominance hierarchy in baboons (Papio papio). Behav Res 53, 1923–1934 (2021). https://doi.org/10.3758/s13428-021-01539-z Abstract: Dominance hierarchies are an important aspect of Primate social life, and there is an increasing need to develop new systems to collect social information automatically. The main goal of this research was to […]
Gelardi, V., Godard, J., Paleressompoulle, D., Claidiere, N., & Barrat, A. (2020). Measuring social networks in primates: wearable sensors versus direct observations. Proceedings of the Royal Society A, 476(2236), 20190737. Abstract – Network analysis represents a valuable and flexible framework to understand the structure of individual interactions at the population level in animal societies. […]
Chunking and associative learning in non-human Primates. Laure Tosatto, Joel Fagot, Dezso Nemeth, and Arnaud Rey. Proceedings of the Evolang Conference, Bruxelles, 2020 This paper describes the learning of visuo-motor sequences in baboons. Baboons firstly learn small chunks that were later concatenated into larger chunks leading to increasingly compressed forms of information
Malassis, R., Dehaene, S. & Fagot, J. Baboons (Papio papio) Process a Context-Free but Not a Context-Sensitive Grammar. Sci Rep 10, 7381 (2020). https://doi.org/10.1038/s41598-020-64244-53 Abstract – Language processing involves the ability to master supra-regular grammars, that go beyond the level of complexity of regular grammars. This ability has been hypothesized to be a uniquely […]
Simon Kirby, Vanessa Ferdinand, Kenny Smith, Joël Fagot and Nicolas Claidière. Cumulative cultural evolution of systematic structure and grammatical complexity in humans and baboons. Proceedings of the Evolang Conference, Bruxelles, 2020 This comparative paper shows a difference between humans and baboons in the way sets of structured behaviours culturally evolve.
Rational after all: changes in probability matching behaviour across time in humans and monkeys Carmen Saldana, Nicolas claidière, Joel Fagot, Kenny Smith. Proceedings of the Evolang Conference, Bruxelles,2020 Here we present a series of experiments designed to directly compare probability matching behaviour across time in adult humans and Guinea baboons
Malassis, R. & Fagot,. (2021). Extraction of structural regularities by baboons adjacent and nonadjacent repetition patterns differ in learnability. Journal of Comparative Psychology, Vol. 135, No. 1, 51– 63. Abstract – Several animal species can discriminate between different sequential patterns based on repetitions of items (eg, ABB vs. ABA), and generalize their performance to sequences […]
