Subject: request recommendation on hardware device for measuring user response time From: "G.

For these experiments, it's critical to measure user response time with high accuracy (ideally to 1 ms). In the past, I used the TDT PI2 hardware timer. Unfortunately, this set of experiments will not be able to use the TDT system. I would like to find out whether there is a stand-alone hardware timer that will do the job. Any advice is greatly appreciated. Thanks. Rob -- G. Robert Arrabito, M.Sc.
