I’m sorry if this had been covered already but my question involves how to have the position of stimulus 2 determined by the position of stimulus 1.
This is most similar to a Posner Attention Network task in which there is a central fixation, then a cue above or below the fixation, and then the target which is presented in the same location as that preceding cue (either above or below fixation). I could do this by just creating trials with this sequence hard-wired, but I think there’s a way to do this with Trial Levels or Rules. I thought that I would be able to set a Trial Level of position (up or down), and then have both events (cue and target) in each trial abide by that rule which is randomly assigned before each trial. So far, in any combination of trial levels (particularly randomize levels before start of each trial) I still haven’t had any luck.
My question seems to have been asked before: http://community.cedrus.com/showthread.php?t=1709&highlight=present+stimuli+location
The last response says that with Superlab 5 this should be possible but not clear how to do it.
Thanks for any help.
