Dear all,
Currently I have an experiment that shows 8 stimuli on the screen per trial and that counterbalances for 16 different groups, however, the way it is programmed has a lot of redundancy: for every different stimulus list a different trial is created, (and also for every different block order a different block type is created, but this is less relevant). I was wondering if there might be an easy way to create a variable 'stimulus_list_name' and set this variable to a different value for each subject, this way I can keep the structure of the trials exactly the same but change the stimulus list per subject. Any suggestions would be welcome,
Roelof
A coarse way of how it is structured here (full experiment is attached, without additional stimuli pictures):
#weighted hpos list for target:

By Brabagazaa - 8/15/2018
+x+xDear all, Currently I have an experiment that shows 8 stimuli on the screen per trial and that counterbalances for 16 different groups, however, the way it is programmed has a lot of redundancy: for every different stimulus list a different trial is created, (and also for every different block order a different block type is created, but this is less relevant). I was wondering if there might be an easy way to create a variable 'stimulus_list_name' and set this variable to a different value for each subject, this way I can keep the structure of the trials exactly the same but change the stimulus list per subject. Any suggestions would be welcome, Roelof A coarse way of how it is structured here (full experiment is attached, without additional stimuli pictures): #weighted hpos list for target: <list hposition_list_set8_1> /items =(50.0,50.0,50.0,50.0,50.0,50.0,50.0,50.0,50.0,50.0,50.0,50.0,50.0,50.0,50.0,50.0,50.0,50.0,28.79,20.01,28.791,71.21,80.0,71.211,50.01,28.79,20.01,28.791,71.21,80.0,71.211,50.01,28.79,20.01,28.791,71.21,80.0,71.211,50.01,28.79,20.01,28.791,71.21,80.0,71.211,50.01,28.79,20.01,28.791,71.21,80.0,71.211,50.01,28.79,20.01,28.791,71.21,80.0,71.211,50.01) /selectionrate = always </list> <list hposition_list_set8_2> /items =(71.21,71.21,71.21,71.21,71.21,71.21,71.21,71.21,71.21,71.21,71.21,71.21,71.21,71.21,71.21,71.21,71.21,71.21,28.79,20.01,28.791,50.0,80.0,71.211,50.01,28.79,20.01,28.791,50.0,80.0,71.211,50.01,28.79,20.01,28.791,50.0,80.0,71.211,50.01,28.79,20.01,28.791,50.0,80.0,71.211,50.01,28.79,20.01,28.791,50.0,80.0,71.211,50.01,28.79,20.01,28.791,50.0,80.0,71.211,50.01) /selectionrate = always </list> <list hposition_list_set8_3> /items =(80.0,80.0,80.0,80.0,80.0,80.0,80.0,80.0,80.0,80.0,80.0,80.0,80.0,80.0,80.0,80.0,80.0,80.0,28.79,20.01,28.791,50.0,71.21,71.211,50.01,28.79,20.01,28.791,50.0,71.21,71.211,50.01,28.79,20.01,28.791,50.0,71.21,71.211,50.01,28.79,20.01,28.791,50.0,71.21,71.211,50.01,28.79,20.01,28.791,50.0,71.21,71.211,50.01,28.79,20.01,28.791,50.0,71.21,71.211,50.01) /selectionrate = always </list> etc, up to 8 lists, 1 per stimulus location #-----------------#TRIAL TYPES:: ------------------------------------------------- LOC1_LOC1_LOC1_LOC1_LOC1_LOC1_LOC1_LOC1_LOC1_LOC1 <trial set8_target_diamond_dis_form_loc1> /ontrialbegin = [values.listnumber = 1;

This is exactly what I was looking for, this way I can just create the different stimulus lists, and cycle through them depending on the subject number, instead of creating trials+blocks for each specific list. As always a very insightful and complete answer thank you very much Dave
