What is the central idea behind the theory of planned behavior?

• A. Decisions are made without emotional involvement
• B. Intentions are influenced by interpersonal relationships
• C. A combination of attitudes, norms, and perceived control shapes intentions
• D. Behavior is a response to rewards and punishments

Answer: (C)

The theory of planned behavior emphasizes that human actions are guided by intentions, which are, in turn, shaped by several factors: personal attitudes towards the behavior, social norms, and perceived behavioral control.

Personal attitudes refer to the individual’s overall evaluation of the behavior in question—whether they perceive it positively or negatively. Social norms involve the perceived social pressure to perform or not perform the behavior, reflecting the influence of people around the individual. Perceived behavioral control pertains to the individual’s belief in their capability to execute the behavior—essentially, whether they feel they have the resources and opportunities necessary to perform the behavior.

This theory highlights the interaction of these three components, asserting that stronger intentions result in a higher likelihood of engaging in the behavior. The interplay of attitudes, norms, and control not only informs our decision-making process but also predicts actual behavior, therefore providing a comprehensive understanding of how psychological factors influence actions in social contexts.
