The game "whack-a-mole," in which the player must "whack" randomly appearing moles with a hammer as quickly as possible when they peek their heads out, is best described as a task

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.
