The French Lexicon Project involved the collection of lexical decision data for 38,840 French words and the same number of nonwords across 1,000 participants from different universities (Université Blaise Pascal, Clermont-Ferrand and Université René Descartes, Paris).  

It was directly inspired on the English Lexicon Project (Balota, Yap, Cortese, Hutchison, Kessler, Loftis, Neely, Nelson, Simpson, & Treiman, 2007).

The data are freely available for research purposes in the Results section.

The French Lexicon Project is funded by the Agence Nationale de la Recherche (ANR) and is supervised by Ludovic Ferrand.
