What is the term for the tendency of behavior to influence thoughts, feelings, and actions?

• A. Self-fulfilling prophecy
• B. Social contagion
• C. Behavior feedback effect
• D. Cognitive dissonance

Answer: (C)

The behavior feedback effect describes how our own actions can shape our thoughts, feelings, and even subsequent behavior. When you act in a certain way—smiling, adopting a confident posture, speaking calmly—your brain and emotions respond to that action, often making you feel happier or more poised. That change in mood or mindset then feeds back into how you behave next, creating a loop where behavior influences internal states and future actions. For example, even if you start by forcing a smile, you may notice an uplift in mood and increased sociability, which then reinforces that behavior. Other terms describe related ideas—self-fulfilling prophecy is about beliefs steering outcomes through actions, social contagion is the spread of emotions or behaviors among people, and cognitive dissonance is the discomfort from holding conflicting beliefs and actions—but the behavior feedback effect specifically captures the way behavior itself can alter thoughts and feelings.
