Magnitude Estimation Data


Title Magnitude Estimation Data
Authors Petzschner Frederike, Glasauer Stefan,
Description Data is stored in two Matlab files. AE_all.mat contains the raw angular estimation data, DE_all.mat the raw distance estimation data for all participants. Each structure in the cell array Data is for one participant and contains pdata (produced distance or angle, that’s the stimulus) and rdata (re-produced distance or angle, the response). There are 3x180 values, first dimension are the three ranges used, so Data{1}.pdata(1,:) contains the stimuli for participant 1 and the short range in the angular estimation experiment (given you loaded AE_all.mat). Call load('AE_all.mat') plot(Data{1}.pdata',Data{1}.rdata','.') xlabel('stimulus (deg)'),ylabel('reproduction (deg)') to plot the angular estimation data for participant one with each range shown in a different color.
