Raw data from 50 subjects that completed a color judgement task. Participants
had to detect if there were more blue or red dots in a cloud of colored dots.
The task included a difficulty manipulation coded by the condition variable.
In the easy condition 60 percent of the dots were either blue or red, and in
the difficult condition 52 percent were either blue or red. In addition the
fixation cross preceding the onset of the dot matrix had a variable presentation
time coded in the fix_duration variable
