    Problem with key release and no response as correct function (case 9547)

    I am having problems with the using the key release (rtr) function with the no response as correct function. I am able to program the following:

    Trial type 1: Participants press and hold a button, wait for a target tone, release button 1 and press button 2.

    Trial type 2: On some trials, participants hear a high or low tone, to which they are not to respond, but continue holding button 1, and then the next trial should start. (Although they could respond as above, but they would be instructed not to...this would be considered a FALSE response.)

    When I use the -1 key code as a correct response while participants are holding button 1, the next trial never initiates (probably because participants are, in fact pressing a button). The next trial won't start, even if they wait until the max style time. The next trial won't start until they release button 1. It seems DirectRT does not read a response as no response unless no key is pressed.

    Is there a way to program the next trial initiation when continually pressing a button? Perhaps there is a way to do this with a meta command for the last part of the trial. For example, after ___ms, start the next trial.

    I appreciate any feedback you can provide. Input files are attached.
