Comparing Perceptual and Preferential Decision Making

This is the complete dataset used in the study: Comparing Perceptual and Preferential Decision Making, by Gilles Dutilh and Jörg Rieskamp. The data set contains three conditions: three preferential decision conditions, with three different risk levels; one perceptual condition. Stimuli across tasks were equal: 10X10 dots matrices representing either a perceptual choice (more white or more black dots) or a preferential choice (do you want to play the gamble where the probability is represented by the number of black and white dots).
