At the same time, they are completing a secondary letter detection task in which they hear different letters of the alphabet and must enter a corresponding key. I want this secondary task to be participant-paced meaning that the next letter is presented after they enter a response. Also, I want the program to exit as soon as 10 pictures appear whether or not the letter detection task is done. <br><br><span style="text-align: -webkit-auto; background-color: rgb(244, 248, 251); ">I've downloaded the dual task example on pstnet support but it does not appear to work the way I want it to. Specifically, the pictures change every time I enter a response for the secondary task rather than after every 3 seconds. I guess the difference between my experiment and the example is that both of the tasks in the example are experimenter-paced whereas in my experiment, one is experimenter-paced and one is participant-paced. Any help would be greatly appreciated! Thanks!</span> <br><br>Khuyen</span></td></tr></tbody></table>
