This tutorial builds a simple version of the Dot Probe Task, a commonly used
measure of attention. Subjects are presented two words, one above the other, and
they are instructed to pronounce the upper word. Occassionally, the upper or lower
word is replaced by a "!", in which cases subjects are instructed to press the spacebar
as quickly as possible. Typically, reaction times to the "!" are shorter when it

- voicekey and keyboard responding
- text presentation
- use of "responsetrial" command to link different types of trials
