Dot Probe

[jarvis24]

If the correctness will be determined on the fly via the random function, then the "Correct" column won't be of much help. It would have to be determined later on as a function of the stimulus placement. Which I think you can get from the actual input file used because DirectRT saves the post-randomization individual input files when you use those functions.

I am also programming a dot probe task and I was wondering would it be possible to use rand() to select from 3 LOC choices? I want to display an object in a quadrant that I have not previously used for a trial. Thanks.
