Ferrand, Ludovic, Boris New, Marc Brysbaert, Emmanuel Keuleers, Patrick Bonin, Alain Méot, Maria Augustinova, and Christophe Pallier. 2010. The French Lexicon Project: Lexical Decision Data for 38,840 French Words and 38,840 Pseudowords. Behavior Research Methods 42 (2): 488–96. pdf

Running make executes the commands in Makefile: the scripts process.words.R and process.pseudowords.R compute the by-item averages from the raw lexical decision time data and produce the final tables.

Intermediate *.csv files contain the raw data with an additional column (‘keep’) signaling the items that are within the subject’ mean+-3stddev range.
