Tutorial: Dot Probe Task
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 appears in the upper position because that is where
subjects are attending.
