Hi, I'm new to psychtoolbox and I'm trying to write a simple task code. The task is to click a mouse button and a stimulus pop out and I also want my Space Key to be the exit button from the trial. I wrote a code but it doesn't work. When using getclick and KbCheck at once a loop, KeyIsDown variable always come to be zero so no keypress is detected. if I remove getclicks I can use keypress. How should I write the could? here's the code I wrote:
I would appreciate your help.
