PDM: choice difficulty + (gain v loss)

Data and MatLab analysis code from 3 experiments looking at perceptual decision making under risk in a motion extrapolation task. <br> These experiments probe behaviour across various loss vs. gain scenarios (see excel spreadsheet for designs), for different levels of dfficulty (curvature in EV func) and for differnt values of parameter k that controls unpredictability of dot path. <br> Also included is analysis code to generate figures used in associated paper. <br> Read the readme file for instructions on how to replicate analyses.<br>
