You need to set that up via the respective <text>, <picture>, etc. elements' /select attributes. If you want a fixed order of trials, you should not sample randomly without replacement (i.e., 'noreplace) but use sequential selection (i.e., 'sequence').

Group: Forum Members Posts: 5, Visits: 1	Hello, In my experiment I need to stimuli presented in the same order of condition, but the items of each condition in random ... <block lexicalDecisionTask> / Trials = [1 = instructions; 2-161 = noreplace (ldtpseudopalabra, ldtpseudopalabra, ldtconcretaiconica, ldtabstractaarbitraria, ldtpseudopalabra, ldtabstractaiconica, ldtpseudopalabra, ldtconcretaarbitraria)] </ block> There are 4 conditions (ldtconcretaiconica, ldtabstractaarbitraria, ldtabstractaiconica, ldtconcretaarbitraria) and filler words. I need the order is above is met, but the items of each condition is present at random for each test pass. There are 20 items per condition and 80 fillers. Any solutions? Thanks!
