Values represent basic convictions about what is good and desirable. They influence our perceptions and attitudes, and generally shape behavior. There are two main types of values: terminal values which are desirable end-states, and instrumental values which are preferable modes of behavior. Different cultures can be assessed based on their values along dimensions such as individualism versus collectivism. Attitudes are learned predispositions to respond favorably or unfavorably to objects, and are influenced by values. Common attitudes studied in organizational behavior are job involvement, organizational commitment, and job satisfaction.
