In
psychology, an
attitude is an expression of favor or disfavor toward a person, place, thing, or event (the
attitude object). Prominent psychologist
Gordon Allport once described attitudes "the most distinctive and indispensable concept in contemporary
social psychology." Attitude can be formed from a person's past and present. Key topics in the study of attitudes include attitude measurement,
attitude change,
consumer behavior, and attitude-behavior relationships.
