I have worked with a variety of experimental design software packages in the past, and I have found DirectRT to be the most user-friendly program that I have encountered. Within hours, I had sophisticated programs up and running. DirectRT’s ability to record very accurate response times from a Windows environment is a very nice asset, and its ability to record voice activated reaction times and actually record and save the responses is wonderful. Also, the support offered by Empirisoft was extremely timely and helpful. I highly recommend DirectRT to anyone who needs to design a reaction time task. I have found this software to be easy to use, efficient, and accurate.
