Data acquisition ends after the 16th stimulus. Such programs may be modified to include reaction time measures, using the Interval Timer which produces 1mS accuracy. The measure from the Interval Timer is simply added to the acquisition channels, such that its readout is continuously registered. The Interval Timer accuracy is independent of sample rate, thus high resolution reaction time can be measured without the need for high speed data sampling, which unnecessarily creates large data volume. There are a number of ways to hook reaction time up, e.g. use of push switches or voice keys.
Wiring is relatively simple.
Straightforward diagrams or ready made systems can be supplied. Reaction time performance can be included in Results data for each trial, and can even be used to modify the stimulus paradigm, so that it adjusts to the subject s ability. There is no limit to the possible variations around this kind of set-up.
