The zip folder "languages" contains materials for the computer-based battery of psychometric tests developed within the MultiplEYE project. The materials have been translated into 25 languages. The zip folder contains 25 folders, one for each language. Each language folder contains five subfolders: instructions, PLAB, Stroop-Flanker, ui_data and WMC. These subfolders contain all the files needed for running the battery in each of the languages. The structure of the language folders and their subfolders corresponds to the one defined in the code of the implementation of the psychometric test battery, and should not be changed.
