Dear Dave,
I'm working on an experiment in which half of the participants will perform a training and the other half will perform a control task. The two experiments are now programmed separately and ready to use, but we need to get them into one file so that participants can access them online from home (our system only allows us to have one task online). Based on the experiment number, we thought that the even numbers could receive the training and the uneven the placebo, which consist of different trials and thus also out of different blocks. I have tried the 'variables' and 'group assignment' command (see an example below), but all it does is present the two tasks in an other sequence. However, the control group may not receive the block presented in the training group and vice verse. I feel like I'm on the wrong track with these commands, so any tips would be welcome!
Thanks!
<variables>
\groep = (1 of 2) [block1 = intro; block2 = practicetraining; block3= testtraining; block4 = vas]
\groep = (2 of 2) [block1 = intro; block2 = practicecontrol; block3= testcontrol; block4 = vas]
