Do I need both DirectRT and MediaLab?

Hi Dolly,

Other design considerations aside, it sounds like either program would be fine for your study. I would suggest using the one with which you are most comfortable.

If the interest in our research protocols using reaction time and DirectRT continues to grow I will be interested in what MediaLab can do for us. For instance, in the current study we’re having consumers take part in one product test via DirectRT and then, after they finish, I need to lean over the consumers to load the next input file for a different DirectRT task. I can't avoid this because I need to use the randomization functions (BGR, WGR) for each task and so I can not combine them into one. With MediaLab, I could randomize that order and eliminate the need to manually change the input files. Correct?

Yes, MediaLab offers a great way to administer multiple DirectRT input files within a single session--especially when you want to randomize or counter balance the DirectRT files that are being administered. Another option is to make batch files in a folder or on the desktop that can launch the DirectRT sessions automatically with the subjects and condition IDs pre-determined. For the latter solution see the DirectRT user's guide for details or online here:
