Attitude Theory explores how individuals develop and change their attitudes, which are evaluations of people, objects, or ideas. It suggests that attitudes consist of three components: cognitive (beliefs), affective (feelings), and behavioral (actions). Understanding these components helps explain how attitudes influence behavior and decision-making. The theory is often applied in various fields, including psychology, marketing, and education. For instance, in marketing, companies use Attitude Theory to shape consumer perceptions and encourage positive attitudes toward their products. By addressing the cognitive, affective, and behavioral aspects, they can effectively influence consumer behavior.
