Answer : reactance theory a model stating that in response to a perceived threat to—or loss of—a behavioral freedom, a person will experience psychological reactance (or, more simply, reactance), a motivational state characterized by distress, anxiety, resistance, and the desire to restore that freedom. According to this model, when people feel coerced into a certain behavior, they will react against the coercion, often by demonstrating an increased preference for the behavior that is restrained, and may perform the behavior opposite to that desired.
Explanation: The answer lies in what is referred to as reactance theory. This theory states that when people are restricted in some way they feel a strong need to resist and fight back to gain their freedom. Just as we traded the playground balls, people who are told not to do something often feel an urge to do the very thing they're denied.
