I intend to write a program that will measure reaction time. I'm not sure yet about the programming language I'll use. The program will be used as part of a psychology experiment. Ideally, I'd like it to run under Windows.
But before I actually go to the effort of writing the program, I'd like to have some confidence that the resulting reaction-time data will be accurate to within a few milliseconds. An acquaintance has told me that it's not really possible under Windows to accurately time events, independent of background processes (antivirus scans, etc.). First of all, is that true? Second, if it's true, how do I get around this problem? Do I use Linux, or...?
