I would like to measure how long it takes a user to press key 1 after display of an instruction key. I've tried using tic toc but from manually checking elapsed time, I know that the variable 'reaction' is not capturing the data correctly. Are there any other ways I could do this other than tic toc? Thanks
one=KbName('1!');
Screen('DrawText',win,'Please press 1',100,100)
Screen('Flip',win)
tic;
while KbEventAvail;
[evt,n]=KbEventGet();
if evt.Keycode==one & evt.Pressed==1;
reaction=toc;
end
end
