What does the theory of planned behavior suggest?

• A. Behavior is entirely determined by external rewards
• B. Intentions and actions are influenced by attitude, subjective norms, and perceived control
• C. Only past behavior influences future intentions
• D. Social pressure has no effect on individual decision-making

Answer: (B)

The theory of planned behavior posits that an individual's intentions, which are the best predictors of actual behavior, are influenced by three key factors: attitude towards the behavior, subjective norms, and perceived behavioral control.

Attitudes reflect how positively or negatively individuals evaluate the behavior, subjective norms concern the perceived social pressures to engage or not engage in the behavior, and perceived behavioral control relates to the individual's perception of their ability to perform the behavior. This theory emphasizes that intention is not only a matter of personal will but is also shaped by external social influences and the belief in one’s own capability to execute the behavior.

Therefore, the correct choice captures the comprehensive nature of human decision-making, showing that behavior is not simply the product of external rewards or prior experiences, nor is it completely free from social influence. Instead, it acknowledges the complexity of human behavior as a function of internal and social factors.
