Mark and Kathy take their 2-year-old son to the supermarket every Saturday. Each week, the same sequence of events unfolds: Their son screams, demanding that they buy him treats.

Punishment referred to any specific changes in an organism's (human beings & animals) environmental surrounding that tends to occur only when a particular response or behavior is being provided and generally reduces the response or behavior to occur again in the future.
