Logging an RT with a window of time

[hfarmer]

Hi Jeff,

Thanks for your help.

I found that command but the problem is that I want the program to always wait 3 seconds before moving on regardless of whether a key is pressed or not. But it seems like to log the reaction time I need to make if a yield command and that means the program will wait until a key is pressed before moving on. Is there a way to log reaction time without using the yield command?

Best,

Harry
