Dear Friends, I have been informed that to measure the reaction time I can use this line of code [keyIsDown, secs, keyCode] = KbCheck; But Kbcheck (secs-time of keypress as returned by GetSecs), and GetSecs returns the time in seconds since the computer started. So what I wanted to know was is the reaction time the secs returned by Kbcheck or do I need to do some sort of calculation to measure reaction time. Regards, Rishi Bhardwaj Rishi Bhardwaj.
