Attitudes are learned predispositions to behave positively or negatively towards people, objects, services or ideas. They have three components - cognitive, affective and behavioral. Attitudes are formed through direct experience, social influences and personality traits. Marketers use various strategies to change attitudes, such as associating products with groups, resolving conflicting attitudes, and altering beliefs about attributes. Theories of attitude formation include cognitive dissonance theory and attribution theory, which provide different perspectives on how behavior can precede and influence attitude.
