First phase of the project - Monosyllabic monomorphemic words - 

In a first phase of the project, we tested 1,826 monosyllabic monomorphemic French words in naming, lexical decision and progressive demasking. Thirty-seven participants (psychology students from Blaise Pascal University) were tested in the naming task, 35 additionnal participants in the lexical decision task and 33 additionnal participants (from the same pool) were tested in the progressive demasking task.

The results of these experiments have been published in Frontiers in Psychology (see below). Following Balota et al. (2004), we took the conservative approach of only including words that achieved at least a 67% level of accuracy in the lexical decision task. This criteria preserved 1,482 words (you can download here the list of the excluded items).

The Chronolex data (mean RTs per word, PEs for LDT, and the predictor variables) are available here in an Excel file.

Main phase of the project - Polysyllabic polymorphemic words -

The French Lexicon Project (FLP) involved the collection of lexical decision data for 38,840 French words and the same number of nonwords.

The full data (1,942,000 reactions times from 975 participants) are freely available below in an Excel file, together with summary files for the words and the pseudowords.

The French Lexicon Project has also been integrated into Lexique (New et al., 2004, 2007), allowing users to select simultaneously several databases they want to work with.
