    Ignored max value for go/no-go task trials

    I am creating a go/no-go task and am having some trouble getting it to work correctly.

    The task is 10 randomized trials long with each trial being a fixed total of 2250ms. For each trial, the stimulus is presented for 750ms with an additional 1500ms of blank screen for responding. The participants are allowed to respond to the stimulus at any point during the trial's 2250ms. When presented with the green circle stimulus, participants are supposed to respond by pressing the spacebar. Should they not make any response, the trial should auto continue after the 2250ms have elapsed. When presented with the red circle stimulus, the participants are supposed to refrain from pressing the spacebar. However, if participants mistakenly press the spacebar during a red circle trial, the reaction time should still be recorded.The participants shouldn't receive any feedback for incorrect responses.

    The problem I am having is that the trials don't auto continue when there is no response and the 2250ms have elapsed. In the hypothetical circumstance that a participant makes no responses, the task should continue on by itself through all 10 trials. However, it is not running that way for some reason that I can't figure out. I've posted this issue before and received some help, but so far no solution has been found.

    I appreciate any help.

    Dear kanichols,

    I ran the Dr. Montgomery.csv file and its corresponding style file. It seemed to do exactly what you wanted it to, based on your most recent post. I've attached a data file from a DirectRT v.2012 session in which I ran those files but did not press any keys. Save for the 4 milliseconds due to my computer, the data file seems to reflect everything you were looking for. Please take a look at it and let me know if this is what you were trying to accomplish.
