Millisecond Forums

Hello,

I'm working on a script and would like to add in a jitter to the pretrial pause. However, the jitter isn't executing and I am instead seeing all trials last exactly 2000ms (the upper limit of the range).

The trial should start with a pause ranging between 100 and 2000 milliseconds, then execute the stimulus sequence, then timeout and branch to the next trial based on a list.

<trial player1turninclusion3to1>
/ pretrialpause = replace(100-2000)
/ stimulustimes = [1=ball3, blank2, blank1; 100=blank3, ball1to3e; 200=blank1to3e; 220=ball1to3d; 320=blank1to3d; 340=ball1to3c; 440=blank1to3c; 460=ball1to3b; 560=blank1to3b; 580=ball1to3a; 680=blank1to3a; 700=ball1]
/ validresponse = (noresponse)
/ timeout = 800
/ branch = [if (counter.inclusionplayer1.selectedvalue == 2) trial.player2turninclusion1to2]
/ branch = [if (counter.inclusionplayer1.selectedvalue == 3) trial.yourturninclusion1to3]
</trial>

Any idea why the pretrialpause isn't jittering?

Thanks!
Jason
