I tried that, but now the stimulus remains on the screen during the posttrial pause. I wanted it to remain on the screen for 3000 ms, followed by a 500 ms blank screen.

Then you ought to do something like

<trial massedstudy1>
/ stimulustimes = [0=massed1; 3000=massed1]
/posttrialpause = 500
/trialduration = 3500
/beginresponsetime=0
/responseinterrupt = frames
/ validresponse = (44,53)
/ correctresponse = (44)
</trial>

with the stimulus' /erase attribute set to true.

Thanks, that works. I'm not sure I understand why, is it because now there is another frame (3000=massed1)? And it doesn't actually show this one?

Yes, there are additional frames and they *are* shown. You don't notice because the stimulus is, of course, identical.

Okay, thanks. I think I got it, but it is counterintuitive to set the text to erase when you actually want it to remain for a specific time. Anyway, thanks for your help!
