In my experiment, I have some stimuli at the beginning of a trial and some at the end. The end stimuli are not based on the participant's response. I have observed that when I have the 2 stimuli at the end of the trial, I don't record any responses i.e. trial.Que.response =0, when I am pressing the valid buttons during the trial. Why might this be the case and can you suggest a workaround for this?

<trial Que>
/ stimulustimes = [0 = shieldK, shieldS; 1 = portETdisplayOn; 2998 = portETdisplayOff; 2999 = portETtrialEnd]
/ timeout = 3000
/ validresponse = (31, 37, noresponse)
/ isvalidresponse = [
if (trial.Que.response == 31) {
values.sKeyPress += 1;
}
/ responsemessage = (31, portETresponse, 1)
/ responsemessage = (37, portETresponse, 1)
/ responseinterrupt = trial
</trial>
