NATURE OF EXERCISE:
Inspection Time is defined in the psychology literature as the speed of intake of information. It's measured by determining the shortest duration required by the user to make a discriminative judgment. Inspection Time is one of the few single information-processing indices that accounts for 20% or greater of intelligence test variance.

RELEVANCE TO EVERYDAY LIFE:
We can all appreciate the benefit of faster information intake. Once again, the driving analogy is the easiest and the one to which people can most easily relate. Just imagine how much safer you and the passengers in your vehicle would be if you could take in information such as the pedestrian in the crosswalk, the pothole, that other vehicle in your path just a split-second faster. But, let's also consider what this faster intake could do for you in athletics. How great an advantage would it be for you to pick up that 90 mph fastball or that 100 mph serve just a little sooner? How about the football quarterback who can pick up the pass rusher a little earlier? Or the point guard who finds his teammate cutting to the basket just a bit quicker?

INSTRUCTIONS:
A Target capital letter will appear in a box in the upper right-hand corner of the screen for 0.5 seconds. Immediately thereafter, three capital letters will be displayed in the middle of the screen for 16 ms (.016 seconds). Your objective is to determine which of the three letters matches the target. If the letter on the left matches, press the LEFT ARROW key on your keyboard. If the letter on the right matches, press the RIGHT ARROW key on your keyboard. If letter in the middle matches, press the LEFT and RIGHT ARROW keys on your keyboard simultaneously.

You must respond correctly 20 times to complete the exercise.

Please note that Reaction Time plays only a minimal role in the scoring of this exercise. Runs with greater accuracy will always have higher scores than runs with lesser accuracy. Reaction Time will only serve as a tiebreaker in runs with identical accuracy.
