Micah observes another child throwing a temper tantrum in front of the candy aisle at the supermarket, and now he throws a temper tantrum whenever he passes by the candy. Micah's behavior supports the _____________ theory?

Is this a science question? If so, I think you're trying to question what kind of behavior this is. It's learned behavior.

As for the name of the theory, I have no clue. Maybe Darwin's Theory? Or was he the guy with the theory of evolution?

...I need to pay more attention in science class XD
