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.
