The **analysis scripts** folder contains R-scripts to conduct all analyses reported in the manuscript and to create all reported tables and figures: 1_DataPrep: Merging and data cleaning. 2_MeanEffects: Descriptives for RTs and accuracies and mean congruency effects. 3_TemporalDynamics: Exploration of the temporal dynamics of the congruency effect by means of delta plots, Lorenz-interferece curves, and the interference distribution index (IDI). 3a\_Bootstrap: Creation of bootstrap samples for the IDI. Results are in the data folder. 4_table: Creation of the tables reported in the manuscript. The **data** folder contains the raw data files owned by Lumos Labs, Inc and made available with the company's permission. There are three datasets on user, game, and trial level, which are merged in the R-script 1_DataPrep. This folder also contains the vincentized RT percentiles and the IDI bootstrap samples used in the R-script 3_TemporalDynamics for both types of practice categorizations.
