Cognitive Dissonance Theory (CDT) Chapter 7 based on the research of Leon Festinger Chapter Summary • Principles of Consistency Theories • Theory at a Glance • Process of Cognitive Dissonance • Assumptions of CDT • Concepts and Processes • CDT and Persuasion • Critique
Principles of Consistency Theories • Mind is intermediary between stimulus and response • New stimuli are organized into a pattern with other previously encountered stimuli • If the new stimulus is inconsistent, then people feel discomfort
Theory at a Glance Cognitive dissonance is the feeling of discomfort resulting from inconsistent attitudes, thoughts and behaviors.
Theory at a Glance People are motivated to reduce dissonance and will: • Ignore opposing viewpoints • Change their beliefs to match their actions (or vice versa) • Seek reassurances after making a difficult decision
Process of Cognitive Dissonance Figure 7.1: The Process of Cognitive Dissonance
Types of Cognitive Relationships • Consonant relationships • Dissonant relationships • Irrelevant relationships
Assumptions of CDT • Human beings desire consistency • Dissonance is created by psychological inconsistencies • Dissonance is an aversive state that drives people to action • Dissonance motivates efforts to achieve consonance
Concepts and Processes • Magnitude of dissonance is the quantitative amount of discomfort felt. • Influencing factors: • Degree of importance of the issue • Dissonance ratio • Rationale to justify the inconsistency
Concepts and Processes • Techniques to cope with dissonance: • Reduce the importance of dissonant beliefs • Add to our consonant beliefs • Eliminate the dissonance
Concepts and Processes • Cognitive dissonance and perception • People will avoid information that increases dissonance • Selection process is basis for avoiding dissonant information Continued…
Concepts and Processes • Types of selection: • Selective exposure • Selective attention • Selective interpretation • Selective retention
Concepts and Processes • Minimal justification is offering the least amount of incentive necessary to obtain compliance. • Minimal justification requires more change on a person's part to reduce dissonance • $1/$20 experiment (Festinger & Carlsmith, 1950)
CDT and Persuasion • Much of CDT research focuses on persuasion and decision making • Studies focused on buyer's remorse: • Automobile Purchases (Donnelly & Ivancevich, 1970) • Gambling (Knox & Inkster, 1968; Brownstein, Read, & Simon, 2004) • Quitting Smoking (Simmons, Webb, & Brandon, 2004)
CDT and Persuasion • Researchers studied CDT in a cult • Festinger, Riecken, & Schachter (1956) • Ethnographic, researchers joined and observed the cult • Cult leaders developed new justifications to assuage dissonance
CDT and Persuasion • Research on the relationship of dissonance and communication strategies • Family Communication (Buzzanell & Turner, 1998) • Female Politicians (Sullivan & Turner, 1997)
Critical Strengths of CDT • Generally useful and explanatory • Offers insight into the relationship among attitudes, cognitions affect, and behaviors • Heuristic • Basis for over a thousand studies
Criticisms of CDT • Lacking a high degree of practical utility • Testability • Difficult to prove wrong • “Biased scanning” (Janis & Gilmore, 1965) • Impression management (Cooper & Fazio, 1984) • Self-perception (Bern, 1967) • Self-affirmation (Steele, 1998)
