Group: Forum Members Posts: 13, Visits: 58	Hello, I currently have the DDT so that it should run 8 delay blocks. but it seems that only 4 of the delay blocks actually run (that is, after the 4th delay is completed, the program will exist ) I was wondering if there was an error in the script that I didn't catch that would account for this. I've attached the script thus far below. Any help on this would be greatly appreciated! Thank you! <summarydata> /columns = (script.startdate, script.starttime, script.subjectid, script.groupid, script.elapsedtime, computer.platform, values.completed, parameters.delayedreward,

Can you explain? My reasoning was that if I added a delay 8 to where the existing code for the other 7 delays were ( and to just copy & paste the previous delays and change it to 8), it would work. I don't quite understand any of this, and that was just my best guess at how to do it. Go back to the original script and try to understand that first. I'll try to explain. <expt> / preinstructions = (generalintro) / postinstructions = (generaloutro) / blocks = [1=foodchoice; 2-8=sequence(money_desc, money_asc, food_desc, food_asc)*] / subjects = (1 of 4) / groupassignment = groupnumber /onexptend = [values.completed = 1] </expt> There are seven delay-"levels". Hence the script runs a sequence of four blocks 7 times. After each set of 4 blocks, the delay-level is increased. You get Delay 1 money_desc -> money_asc -> food_desc -> food_asc Delay 2 money_desc -> money_asc -> food_desc -> food_asc Delay 3 money_desc -> money_asc -> food_desc -> food_asc and so forth. What's responsible for selecting the next delay level after each chunk of four blocks is the code I pointed out earlier <block food_asc> / onblockbegin = [values.object=values.foodchoice; values.blocktype="food"; values.ip_found=0] / onblockbegin = [values.immediateresponsestreak=0; values.delayedresponsestreak=0] / onblockbegin = [values.previousresponse=""] / onblockbegin = [values.blockcount+=1; values.trialcount=0] / onblockbegin = [values.order="ascending"; values.ip_asc=0.00; values.ip=0.00] / onblockbegin = [if(mod(values.blockcount,4)==1 \|\| mod(values.blockcount,4)==3) values.ip_desc=0.00] / onblockbegin = [if(mod(values.blockcount,4)==1) values.delay=list.delays.nextvalue] / trials = [1-26=discounttrial; 27=compute_ip] </block> (analogous code exists in the other <block> elements, of course). Now, if you want to run 8 delays and only for the food items, you need to run 8 sequences of two* blocks. And you need to select the next delay level after each chunk of two blocks, not 4 or 8.
