<blockquote type=cite class=cite cite="">Hi,<br><br>
I'm trying to program a dual task in which participants are presented
with a series of pictures that appear for 3 seconds each. 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>
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!
