## randomized two blocks (1 and 3) - second block in-between (not...

 Author Message LimaHD  New Member         Group: Forum Members Posts: 2, Visits: 5 Hi, I'm trying to randomize the order of two blocks. But I also want another block in between those two blocks. Here is what I did before (when I didn't need the block in between):/ preinstructions = (introduction, instructions1)/ blocks = [1-2 =noreplace(vid_1, vid_1_sl); 3= demographics]/ postinstructions = (end)Now I tried this, but I could make it work: / preinstructions = (introduction, instructions1)/ blocks = [1-3 =noreplace(vid_1, vid_1_sl); 2=stroop;  4= demographics]/ postinstructions = (end)I'm trying to randomize block 1 and 3 without randomizing block 2, as it has to come second. Only the order of 1 and 3 have to be randomized. Do you have any idea how I have to change it?Thanks for your help.
