This is an experiment investigating the ability to respond to stimuli.
The task involves pressing the corresponding number that appears on the screen
as quickly and accurately as possible. You will then have a break between trials.
After training, you will do simple addition problems and then complete the task once more.
The goal of each trial is to correctly respond to as many numbers as possible before the
the trial ends.
It is important that you respond as quickly as you can, but not at the expense of making
errors because.
