The CLLE laboratory (Cognition, Languages, Language, Ergonomics) is a CNRS UMR created in January 2007 and mainly hosted at the University Toulouse Jean Jaurès.

The laboratory is part of the Institute of Human and Social Sciences of the CNRS and is mainly attached to the section 34 of the CNRS (Language Sciences) and secondarily to the section 26 of the CNRS (Cognition, Brain, Behavior) of the Institute of Biological Sciences of the CNRS. CLLE is thus a multidisciplinary research unit in the field of Cognitive Sciences: its work covers the fields of linguistics, psychology, computer science, philosophy, education and neuroscience.

It has been restructured into three teams since January 2021:

a Languages and Language team structured around research on linguistic structures, the study of Romance languages, European languages, Occitan (describing, formalizing, tooling, comparing), the didactics of French and languages, and teacher training (coordinated by Anne Dagnac & Claudine Garcia-Debanc).
A Language and Cognitive Processes team developing research on digital tools, on learning in the field of education and on interactions, multimodality, variation and culture (coordinated by Fabio Montermini & Nathalie Huet).
A Cognition in complex situations team whose research is structured around cognition and innovative technologies, society-individual interactions, and memory, evaluation and decision (coordinated by Céline Lemercier & Valérie Le Floch).
