Testing semantic compositionality in baboons (papio papio) through relearning and generalization

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 […]

Agent preference in chasing interactions in guinea baboons ( papio papio ): uncovering the roots of subject–object order in language

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 […]

The lifetime of sequential memory traces in the absence of language

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 […]

Can non-human primates extract the linear trend from a noisy scatterplot

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 […]

A comparative study of causal perception in guinea baboons (papio papio) and human adults

Floor Meewis, Iris Barezzi, Joël Fagot, Nicolas Claidière, Isabelle Dautriche. A comparative study of causal perception in Guinea baboons (Papio papio) and human adults. PLoS ONE, 2024, 19 (12), pp.e0311294. ff10.1371/journal.pone.0311294ff. ffhal-04847917f In humans, simple 2D visual displays of launching events (“Michottean launches”) can evoke the impression of causality. Direct launching events are regarded […]

Chunking as a function of sequence length.

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. […]

Sequence learning and chunk stability in guinea baboons (papio papio)

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 […]

On the role of interference in sequence learning in guinea baboons (papio papio).

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 […]

Simple questions on simple associations: regularity extraction in non-human primates

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 […]

The dynamics of chunking in humans (homo sapiens) and guinea baboons (papio papio)

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 […]

Age effect in expert cognitive flexibility in guinea baboons (papio papio)

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 […]

Simultaneous learning of directional and non-directional stimulus relations in baboons

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 […]
