Imagine it's your birthday, and you're finally old enough to buy a lottery ticket. You go to the local convenience store, purchase your first ticket and scratch it off to see if you won any money. If this happened to you and you won, you would probably be likely to buy more lottery tickets in the future because your behavior was rewarded. However, if this happened to you and you lost, you would probably be less likely to buy more lottery tickets in the future because your behavior was punished by losing money.
