Attitudes have three main components - cognitive, affective, and behavioral. The cognitive component involves one's thoughts and beliefs, the affective component involves emotions and feelings, and the behavioral component involves tendencies to act in a certain way. The document also discusses factors that influence attitude formation and change, such as experiences, context, and cognitive dissonance. Measurement of attitudes can involve self-report measures, physiological measures, or covert measures.
