The answer to the blank space in the question is a reaction time task.
A reaction time task measures an individual’s basic cognitive processes of perception and ability to respond based on what she or he perceives. Whack-A-Mole is a great example of this since the individual has to process what he or she sees (the Mole) and immediately responds by hitting the mole with the hammer. An individual with a good perceptual speed and response time would be good in this game.
