Laura Ordonez Magro, Leonardo Pinto Arata, Joël Fagot, Jonathan Grainger, Arnaud Rey. The Lifetime of Sequential Memory Traces in the Absence of Language. Cognitive Science, 2025, 49 (8) Statistical learning allows us to implicitly create memory traces of recurring sequential patterns appearing in our environment. Here, we study the dynamics of how these sequential […]
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. […]
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 […]
Rey A, Fagot J. Associative learning accounts for recursive-structure generation in crows. Learn Behav. 2023 Dec;51(4):347-348. doi: 10.3758/s13420-022-00564-y. Epub 2023 Jan 3. PMID: 36595212. Abstract – Recursive sequence generation (i.e., the ability to transfer recursive patterns to novel items) was recently reported in crows (Liao et al., 2022, Science Advances, 8[44], eabq3356). Here, we […]
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 […]
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 […]
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. […]
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 […]
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 […]
Malassis, R., Rey, A. & Fagot, J. (2018). Non-adjacent dependencies processing in human and non-human primates. Cognitive Science. First published: 20 May 2018, https://doi.org/10.1111/cogs.12617 Abstract – Human and non-human primates share the ability to extract adjacent dependencies and, under certain conditions, non-adjacent dependencies (i.e., predictive relationships between elements that are separated by one or […]

Topics in Cognitive Science. First published: 21 May 201. http://dx.doi.org/10.1111/tops.123433 Abstract – Extracting the regularities of our environment is a core cognitive ability in human and non‐human primates.

Fagot, Joël (2017). Orthographic processing in animals : implications for comparative psychologists. Learning and Behavior, 45(3), 209-210 Abstract – Two recent studies have shown that pigeons and baboons can discriminate written English words from nonwords, and these findings were interpreted as demonstrating that orthographic processing is possible in absence of linguistic knowledge. Here, I […]
