Hello! For my study, I am testing whether people have a preference for the Republican or the Democratic political party. I am running political honestly scores across the screen, for both parties. My plan is to have 80 trials for each participant where on 1/2 of trials the democrat candidate is more honest (Demplus) and the other 1/2 the republican candidate is more honest (Repplus). I want these to be fully randomized across trials such that each participant essentially has a different order of trials where Dem is more honest and Rep is more honest. However, currently, my script doesn't accomplish this as I instead have 40 trails with Republicans scores and then 40 Democratic scores. Is there a way that I can randomize how each trial appears on the screen within a block?

You're not randomizing anything here. For trials 1-40 you're sampling one element -- <trial RepB>. For trials 40-80 you're sampling another single element, <trial DemB>.
It's the same as saying
/trials = [1-40 = RepB; 41-80 = DemB]
There's nothing to sample randomly if there's only one element.
Further, notice that sampling *trials* at the block-level, and sampling *stimuli* at the trial-level are two completely separate and distinct things.

+x+x+x+xHello! For my study, I am testing whether people have a preference for the Republican or the Democratic political party. I am running political honestly scores across the screen, for both parties. My plan is to have 80 trials for each participant where on 1/2 of trials the democrat candidate is more honest (Demplus) and the other 1/2 the republican candidate is more honest (Repplus). I want these to be fully randomized across trials such that each participant essentially has a different order of trials where Dem is more honest and Rep is more honest. However, currently, my script doesn't accomplish this as I instead have 40 trails with Republicans scores and then 40 Democratic scores.

I want these to be fully randomized across trials such that each participant essentially has a different order of trials where Dem is more honest and Rep is more honest. However, currently, my script doesn't accomplish this as I instead have 40 trails with Republicans scores and then 40 Democratic scores. Is there a way that I can randomize how each trial appears on the screen within a block? <item Demplus> /1 = "score1+" /2 = "score2+" /3 = "score3+" </item> <item Demminus> /1 = "score1-" /2 = "score2-" /3 = "score3-" </item> <item Repplus> /1 = "score1+" /2 = "score2+" /3 = "score3+" </item> <item Repminus> /1 = "score1-" /2 = "score2-" /3 = "score3-" </item> <text Demplus1> /items = Demplus /txcolor = (blue) /animation = path (5000, 1, 0%, 90%, 100%, 90%) / select = list.Demplusitems.nextindex </text> <text Demplus2> /items = Demplus /txcolor = (blue) /animation = path (5000, 1, 0%, 90%, 100%, 90%) / select = list.Demplusitems.nextindex </text> <text Demplus3> /items = Demplus /txcolor = (blue) /animation = path (5000, 1, 0%, 90%, 100%, 90%) / select = list.Demplusitems.nextindex </text> <list Demplusitems> / poolsize = 3 / selectionrate = always / replace =true </list> <text Demminus1> /items = Demminus /txcolor = (blue) /txbgcolor = (white) /animation = path (5000, 1, 0%, 90%, 100%, 90%) / select = list.Demminusitems.nextindex </text> <text Demminus2> /items = Demminus /txcolor = (blue) /animation = path (5000, 1, 0%, 90%, 100%, 90%) / select = list.Demminusitems.nextindex </text> <text Demminus3> /items = Demminus /txcolor = (blue) /txbgcolor = (white) /animation = path (5000, 1, 0%, 90%, 100%, 90%) / select = list.Demminusitems.nextindex </text> <list Demminusitems> / poolsize = 3 / selectionrate = always / replace =true </list> <text Repplus1> /items = Repplus /txcolor = (red) /animation = path (5000, 1, 0%, 90%, 100%, 90%) / select = list.Repplusitems.nextindex </text> <text Repplus2> /items = Repplus /txcolor = (red) /animation = path (5000, 1, 0%, 90%, 100%, 90%) / select = list.Repplusitems.nextindex </text> <text Repplus3> /items = Repplus /txcolor = (red) /animation = path (5000, 1, 0%, 90%, 100%, 90%) / select = list.Repplusitems.nextindex </text> <list Repplusitems> / poolsize = 3 / selectionrate = always / replace =true </list> <text Repminus1> /items = Repminus /txcolor = (red) /animation = path (5000, 1, 0%, 90%, 100%, 90%) /select = list.Repminusitems.nextindex </text> <text Repminus2> /items = Repminus /txcolor = (red) /animation = path (5000, 1, 0%, 90%, 100%, 90%) /select = list.Repminusitems.nextindex </text> <text Repminus3> /items = Repminus /txcolor = (red) /animation = path (5000, 1, 0%, 90%, 100%, 90%) /select = list.Repminusitems.nextindex </text> <list Repminusitems> / poolsize = 3 / selectionrate = always / replace = true </list> <list Demplus> /items = (text.Demplus1, text.Demplus2, text.Demplus3, text.Repminus1, text.Repminus2, text.Repminus3) /selectionrate =always /selectionmode =random /replace = false </list> <list Repplus> /items = (text.Demminus1,text.Demminus2,text.Demminus3, text.Repplus1,text.Repplus2, text.Repplus3) /selectionrate =always /selectionmode =random /replace = false </list> <trial DemB> / validresponse = ("E", "I") / correctresponse = ("E") / beginresponsetime = 0 /ontrialbegin = [ trial.DemB.insertstimulustime(list.Demplus.nextvalue, 0);

41-80 = replace (DemB)] </block> You simply do <block Demplus> /trials = [1-80 = noreplace( RepB, DemB)]</block> which will give you 40 RepB trials and 40 DemB trials in random order. But I already have "replace" in my block, shouldn't that already randomize it while replacing the values. Please let me know if I am thinking about this incorrectly. <block Demplus> /trials = [1-40 = replace( RepB); 41-80 = replace (DemB)] </block> You're not randomizing anything here. For trials 1-40 you're sampling one element -- <trial RepB>. For trials 40-80 you're sampling another single element, <trial DemB>. It's the same as saying /trials = [1-40 = RepB; 41-80 = DemB] There's nothing to sample randomly if there's only one element. Further, notice that sampling *trials* at the block-level, and sampling *stimuli* at the trial-level are two completely separate and distinct things. So then if I wanted to randomize the selection of trials on the block-level, how would I go about doing that? I don't want 40 trials and RepB then 4o trials of DemB, I would like both 40 to be mixed in/randomly picked. I answered that here https://www.millisecond.com/forums/FindPost28218.aspx okay, thanks again Dave!
