If you are interested in understanding human behavior, you must have come across the Theory of Planned Behavior (TPB). This theory provides insights into how individuals make decisions and act on them.

It suggests that behavior is influenced by three factors – attitude, subjective norms, and perceived behavioral control. While TPB has been widely accepted and used by researchers, it has also been subject to criticism for its limitations. To address these limitations, a new model was proposed – the Reasoned Action Approach (RAA).

The RAA model is an evolution of TPB as it incorporates some of its key concepts while addressing some of its limitations. The RAA model proposes that human behavior is determined by two primary factors – behavioral intention and attitude.

Behavioral intention is a combination of an individual’s attitude towards the behavior, subjective norms, and perceived behavioral control- the same factors that TPB considers. However, unlike TPB which focuses on the role of perceived behavioral control in predicting behavior, RAA emphasizes the role of attitude.

The RAA model suggests that attitudes are formed based on beliefs about the outcomes associated with a particular behavior. These beliefs can be either positive or negative and can influence an individual’s willingness to engage in the behavior. The stronger an individual’s positive attitudes towards a particular behavior are, the more likely they are to engage in it.

In addition to attitude, RAA also recognizes the importance of social norms in determining behavior. Social norms refer to the beliefs individuals hold about what others think they should do or not do.

In other words, social norms reflect perceptions about what is considered socially acceptable or unacceptable. These perceptions can influence an individual’s decision to engage in a particular behavior.

Overall, while both TPB and RAA aim to explain human behavior through cognitive processes such as attitudes and beliefs, RAA places greater emphasis on attitudes than TPB does. Moreover, RAA recognizes that social norms can also play a significant role in shaping behavior. By taking these factors into account, RAA provides a more comprehensive understanding of human behavior.

To summarize, while TPB has been widely accepted and used by researchers, RAA is an evolution of this theory that addresses some of its limitations. While both theories consider attitudes and beliefs as key factors that influence behavior, RAA places greater emphasis on attitudes and recognizes the importance of social norms. By incorporating these elements, RAA provides a more comprehensive understanding of human behavior than TPB does.
