Response devices

[David McFarlane]

Tobi,

For more money you could also create custom 
keyboard designs with the Ergodex DX1 
(http://www.ergodex.com/mainpage.htm ), although 
I don't think it's timing is any better than an 
ordinary keyboard, and I like your inexpensive custom design better.

The latest reference I have on keyboard timing is 
Plant, R. R., & Turner, G. (2009), "Millisecond 
precision psychological research in a world of 
commodity computers: New hardware, new problems?" Beh Res Meth 41: 598-614.
