Attitudes are associated beliefs and behaviors towards some object. They are not stable, and because of the communication and behavior of other people, are subject to change by social influences, as well as by the individual's motivation to maintain cognitive consistency when cognitive dissonance occurs—when two attitudes or attitude and behavior conflict. Attitudes and attitude objects are functions of affective and cognitive components. It has been suggested that the inter-structural composition of an associative network can be altered by the activation of a single node. Thus, by activating an affective or emotional node, attitude change may be possible, though affective and cognitive components tend to be intertwined.
There are three bases for attitude change: compliance, identification, and internalization. These three processes represent the different levels of attitude change.
Compliance refers to a change in behavior based on consequences, such as an individual's hopes to gain rewards or avoid punishment from another group or person. The individual does not necessarily experience changes in beliefs or evaluations of an attitude object, but rather is influenced by the social outcomes of adopting a change in behavior. The individual is also often aware that he or she is being urged to respond in a certain way.
Compliance was demonstrated through a series of laboratory experiments known as the Asch experiments. Experiments led by Solomon Asch of Swarthmore College asked groups of students to participate in a "vision test". In reality, all but one of the participants were confederates of the experimenter, and the study was really about how the remaining student would react to the confederates' behavior. Participants were asked to pick, out of three line options, the line that is the same length as a sample and were asked to give the answer out loud. Unbeknown to the participants, Asch had placed a number of confederates to deliberately give the wrong answer before the participant. The results showed that 75% of responses were in line with majority influence and were the same answers the confederates picked. Variations in the experiments showed that compliance rates increased as the number of confederates increased, and the plateau was reached with around 15 confederates. The likelihood of compliance dropped with minority opposition, even if only one confederate gave the correct answer. The basis for compliance is founded on the fundamental idea that people want to be accurate and right.
