The paradigm I am thinking of is a single case methodology. Part of the basic idea is astonishingly like the recent discussions on how the various OSs allocate cycles to different processes. My guess is that the attentional component of ADHD is not detectable with brief, simple tasks. Start cranking up the complexity, add competing attentional demands or extend the duration of attention required, and the ADHD should kick in. like Mac vs Unix. Following your suggestion for a calibration process, I've thrown together 'clicker', a simple array of buttons, most blue with a few yellow ones on each line. The task is to disappear all the latter by clicking on them. I measure latency and errors. Seems to be a fair measure of mousability...but as to calibration...? What would I count as "bias"? Does anyone know if there are any system variables I can look up to check for mouse sensitivity? I know that still leaves a lot of problems (thanks for the other replies!) but, one step at a time.
