Designing a Flanker task in DirectRT

    Designing a Flanker task in DirectRT

    I'm trying to set up a modification of the flanker task in DirectRT. In each trial, there would be a picture (centered) surrounded by four repetitions of the same word. The solution I could think of was to set up a trial, with the picture as a stim, followed by four stims with the word inserted in the trial (i.e., ~good), where each is overlaid on the target picture at .8,0,0; .2,0,0; 0,.8,0; 0,.2,0 --
    The only problem with that is that the words do not appear simultaneously with the picture, and there is a very short lag of time until they all appear. Is there any way to have four repetitions of the same word appear simultaneously with the target picture?

    Thanks

    With my adviser's help, I figured out a way to design the task correctly. I set the time on the word repetitions for 0, that way no time lag would happen when it's time to present each of the four words.
