This document discusses different theories of attitudes. It defines an attitude as an evaluative statement indicating one's feelings toward people, objects, events, or situations. It then outlines three major attitude theories: balance theory, which involves how a person relates to others and objects; congruity theory, which is based on how consistently a person holds attitudes; and cognitive dissonance theory, which examines the link between attitudes and behaviors and proposes that people seek to reduce inconsistencies between their actions and beliefs.
