Hi,

I'm trying to create code where I wait for a user's key response for 5 seconds. If there's no response in 5 seconds, the screen (using Psychtoolbox) should advance.

I've tried KbWait(5), as in 5 seconds, but of course I think this is too good to be true.

Is there anything else I should try?

Thanks so much!

在 MATLAB Online 中打开

try this:

startTime= WaitSecs(0);
KbWait([], 0 ,startTime+2)
