% expInfo | configuration for state switch word version (struct)
% Written by Julian Kosciessa (kosciessa@mpib-berlin.mpg.de)
% 170704 - incorporated thresholds
% 170809 - incorporated state dimensionality & accompanying
% randomization changes
% 170814 - introduce run format; adapted timing
% 170816 - created word randomization version, deleted dot entries
% 170821 - created practice version
% 170823 - changed randomization to account for switch probability
% 170829 - included RT feedback
% 171023 - replaced repelem with version working on older MATLAB versions
% - draw stimuli from separate practice set
