I have used a Roland R-8 Rhythm Composer for this purpose. It is essentially a fully programmable MIDI drum machine with an array of twenty 1-inch-square buttons. The buttons are flat and square, and have very little travel - they are made to be "tapped". It sports audio in and out, 8 MIDI jacks, tape in/out, etc. With the MIDI-to-serial port adapter, this baby plugged right into a Mac which was running a MAX program to play sounds and record reaction time responses from the R-8. I'm not sure if you need to (or can) buy this item (or a similar one). Something like the Roland SPD-11 might be an interesting alternative. It is a simple array of about six 3-inch-square flat drum pads... But I *borrowed* the R-8 I used from our computer music department - try that first, 'cause they ain't cheap.
