How would I get a ttl signal locked to either an errormessage or a responsemessage? I already have a signal locked to the stimulus presentation but I need one locked to the feedback presentation as well. Code for a trial is below: Thanks!
<trial setAtarget1corrleft>
/ validresponse = (lbuttondown, rbuttondown)
/inputdevice = mousekey
/ correctresponse = (lbuttondown)
/validresponse = (lbuttondown, rbuttondown)
/ posttrialpause = 1500
/stimulustimes = [0=setAtarget1left; 0=setAtarget2right 0=stimulussignal]
/errormessage = (errormessage, 0)
/correctmessage = (correctmessage, 0)
/responsemessage = (lbuttondown, corr, 0)
/responsemessage = (rbuttondown, incorr, 0)
</trial>
