Group: Forum Members Posts: 23, Visits: 59	Hi there, I have amended the Alcohol Stroop task to suit my needs, and it's working great. Currently, it is running with two blocks (Each block repeats the word list 2 times, leading to a total of: 40 critical words + 40 control words per block). However, I would like instead to have 4 blocks, with each block running the list just once (20 words per list), so it would like like: Block 1: 20 critical, 20 control Block 2: 20 critical, 20 control Block 3: 20 critical, 20 control Block 4: 20 critical, 20 control Essentially the overall total of words won't change (2 blocks =160 total, or 4 blocks=160 total), but the participant would get a short break between each block . I have tried amending the highlighted part below but it hasn't been able to run. Does anyone have suggestions on which part of the script I would need to edit to get the task to run the way I would like it to? I am sure there is a very simple solution, but I am extremely new to this so it's all mind-boggling to me. Thank you in advance for your assistance! stefania

Thank you in advance for your assistance! stefania Reduce the number of trials in the respective <block>'s /trials attribute to 40. Edit the <expt> element to run 4 blocks instead of only two. <expt> / blocks = [ 1 = StartInfo; 2 = Practice; 3= AlcoholStroop; 4 = Rest; 5 = AlcoholStroop; 6 = Rating; ] / postinstructions = (end) /onexptend = [values.completed = 1] </expt> becomes something like <expt> / blocks = [ 1 = StartInfo; 2 = Practice; 3 = AlcoholStroop; 4 = Rest; 5 = AlcoholStroop; 6 = Rest; 7 = AlcoholStroop; 8 = Rest; 9 = AlcoholStroop; 10 = Rating; ] / postinstructions = (end) /onexptend = [values.completed = 1] </expt>
