DirectRT has the potential to simplify the life of any experimenter. As a researcher with no experience in computer programming, but with some complicated experimental requirements, DirectRT has been an invaluable tool for me. It offers great flexibility and precise control, via an intuitive Windows-based interface. Various types of experiments, from ratings of pictorial stimuli to response times of verbal stimuli, can easily be conducted either independently or simultaneously. Learning to use DirectRT is simple and quick. I had programmed my first experiment within 2 or 3 hours of installing the software on my lab computers. The instruction manual is comprehensive, including several easy-to-grasp tutorials, and the experiments can actually be programmed in the familiar Microsoft Excel environment. Technical support from the folks at Empirisoft is speedy, excellent, and personalized--when I encountered a problem I didn't know how to solve, they worked with me to create a solution. And finally, the data are saved in a well-organized manner that facilitates immediate analysis. I do not hesitate to recommend DirectRT to experimenters at all levels of experience.
