So I know I can have every other subject do a series of tasks. But I dont want that. I want it to be random for each participant that they either go through one block or another, and there are four blocks like that in my task. So for example, I thought I could do a branch. It calls blockdsl, and then from there determines what block is ran. This works, but only for the first block encountered ( i.e., blockdsl, blockdss, blockssl, blocss) after the block it branches to concludes it skips to the last block in the experiment (end). How can I get it to go through back to the next block in the expt?
Excerpt of code:
<block blockdsl>
/ branch = [if(values.side3 < = 50) {block.blockdsl1}{block.blockdsl2}]
</block>
<block blockdsl1>
/ trials = [1,3,5,7,9,11,13,15,17,19,21,23,25,27,29,31,33,35,37,39,41,43,45,47,49,51,53,55,57,59,61,63,65 = d1; 2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,50,52,54,56,58,60,62,64,66 = sn1; 67 = choice; 68 = forward; 69 = fixation;]
</block>
<block blockdsl2>
/ trials = [1,3,5,7,9,11,13,15,17,19,21,23,25,27,29,31,33,35,37,39,41,43,45,47,49,51,53,55,57,59,61,63,65 = sn1; 2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,50,52,54,56,58,60,62,64,66 = d1; 67 = choice; 68 = forward; 69 = fixation;]
</block>
<expt main>
/ blocks = [1 = instructions; 2 = taskinstructions; 3-6 = noreplace (blockss, blocksr, blockt, blockd); 7- 10 = noreplace(blockdss, blocktss, blockdsl, blocktsl); 11 = end;]
</expt>
