    Is this the kind of dot probe design you're looking at? If so, then yes, DirectRT will do it no problem. If you are looking at any significant variation in design, let me know and I'll tell you DirectRT can accommodate.
    Participants are asked to stare at a fixation cross on the center of the screen. Two stimuli appear randomly on either side of the screen. The stimuli are presented for a duration of 500ms before a dot is presented in the location where one of the stimuli was presented, at which point participants are instructed to respond on a remote key pad which side of the screen the dot appeared. Latency is measured. The fixation cross appears again for several seconds and then the cycle is repeated.

    I don't have one. Try to get as far as you can with it and then post it here as a zip file. I'll help you work out anything you can't figure out. If you're new to DirectRT, you might check out the tutorial, payong special attention to compound screens. Also be check out "min-max" values in the user's guide. That will help you with the 500ms limit.

    Please refer to the following thread on the Empirisoft Support forums: http://www.empirisoft.com/support/sh...t-Probe-script. It has an example input file of a dot probe task for DirectRT along with information about how to place two words on the screen at the same time.


    You may also find this forum thread that talks about randomly placing the dot: http://www.empirisoft.com/support/sh...1632-Dot-Probe.
