In this trial, a fixation cross is displayed for 1s and then a target stimulus is displayed. Participants respond to the target with a key press. I can't find a way to make the target stimulus stay visible on the screen for the remaining duration of the trial after participants respond. Any help would be appreciated.
<trial SART.nontarget>
/trialduration = 2500
/posttrialpause = 100
/stimulustimes = [1=fixation;1000=nontarget]
/correctresponse = (57)
/validresponse = (57, noresponse)
</trial>
