THE CONCEPT OF "REACTANCE"  :  a psychological response people have when they perceive their freedom to choose or act is being restricted. It was introduced by psychologist Jack Brehm in 1966. Reactance arises when someone feels their autonomy or control is threatened, prompting them to reassert their freedom by doing the opposite of what they're being told, often as a form of resistance. For example, if someone is told they must not engage in a certain behavior, they might be more inclined to do that exact thing as a way of re-establishing their sense of freedom. This is commonly seen in children, teenagers, or even adults when they face strict rules, punishments, or prohibitions. Reactance is often linked to rebellious behavior and can make attempts at control, like punishment, backfire if they feel too authoritarian or unfair.
