NATURE OF EXERCISE:
Recognition Reaction Time, also referred as Go/NoGo Reaction Time, uses a bit more of the cognitive process than Simple Reaction Time (Exercise 1 series). Instead of simply responding to the presentation of a stimulus, it requires the user to respond to one particular stimulus but ignore all other stimuli. Accordingly, it not only challenges your ability to recognize the correct stimulus, but it also challenges your ability to inhibit inappropriate reactions. As a result, reaction time for the Go portion of the exercise is typically 50 - 75 milliseconds slower than Simple Reaction Time.

RELEVANCE TO EVERYDAY LIFE:
Impulsiveness is a problem for so many of us, whether in our personal life (friends, relationships, shopping) or in our business and financial matters (unwise investments, imprudent remarks made to a co-worker or supervisor). Training your inhibitory mechanisms increases your ability to deal with unexpected surprises that may arise in your life.

INSTRUCTIONS:
A vertical display of lights, similar to a traffic signal, is presented. If the light changes from red to green, press the DOWN ARROW key on your keyboard as quickly as possible. If the light changes from red to yellow, do NOT press any key. If you press the key before the light changes or when it turns yellow, this counts as an error and serves to reduce your score.

You must respond/not respond correctly 20 times to complete the exercise.
