Attitude change is a fascinating and complex area of study within social psychology. Over the years, researchers have proposed various theories to understand the processes involved in changing attitudes. These theories categorize attitude change into different frameworks, such as consistency theories, learning theories, social judgment theories, and functional theories. By exploring these theories, we can gain insights into how attitudes are formed, how they can be modified, and the underlying motivations that drive these changes. Understanding the mechanisms of attitude change is crucial for effective persuasion and the design of persuasive messages in various contexts.

II. Historical Perspective

A. Emphasis on definition and measurement of attitudes before World War II

• Prior to World War II, the focus in attitude research was primarily on defining and measuring attitudes.
• Survey-based studies were common during this period, providing valuable correlational findings but limited insights into causality.
• Experimental techniques such as control groups or comparison groups were notably absent.

B. Influence of experimental psychologists during World War II

• World War II marked a significant turning point in attitude change research, driven by the involvement of experimental psychologists like Carl Hovland.
• The persuasive effects of propaganda became a crucial topic of Army-sponsored research.
• True experimental techniques were employed to study the persuasive effects, bringing a shift towards experimental approaches in studying attitude change.

C. Theories developed by Hovland and his associates

• Carl Hovland and his associates continued their attitude change research after the war at Yale University.
• The theories developed by this group served as an organizational framework for the study of attitude change.
• Their research and theory building were rooted in the behaviorist perspective, seeking to establish relationships between attitudes and observable outcomes in learners.

D. Shift from survey-based studies to experimental techniques

• The influence of Hovland and his associates led to a significant shift from survey-based studies to experimental techniques in attitude change research.
• Experimental methods, including control groups and manipulation of variables, were implemented to study the persuasive effects of different interventions.
• This shift allowed for a better understanding of the causal relationships between attitude change and various factors, paving the way for more rigorous research in the field.

III. Consistency Theories

A. Basic assumptions and need for consistency

• Consistency theories in attitude change posit that individuals have a fundamental need for consistency between their attitudes, behaviors, and among attitudes and behaviors.
• Inconsistency causes discomfort, prompting individuals to seek balance or consistency by adjusting their attitudes or behaviors.

B. Balance theory and relationships among perceiver, person, and object

• Balance theory, a consistency theory, focuses on the relationships between the perceiver, another person, and an object.
• These relationships are categorized as positive or negative based on the perceiver’s cognitive perceptions.
• The theory proposes that there are four balanced and four unbalanced configurations, with unbalanced states recognized as being unstable.

C. Cognitive dissonance theory and reduction of inconsistency

• Cognitive dissonance theory, one of the most influential consistency theories, addresses the reduction of inconsistency.
• Dissonance occurs when there are logical or psychological inconsistencies among cognitive elements or beliefs about oneself, behavior, or the environment.
• Dissonance motivates individuals to reduce the inconsistency and return to consonance, leading to attitude change.

D. Research example: Simonson’s study of dissonance theory principles

• Simonson’s (1977) study exemplifies a consistency theory approach by utilizing cognitive dissonance theory.
• The study aimed to improve student attitudes toward an instructional activity through a formal program of attitude change.
• The research involved randomly assigning students to different treatment groups and assessing attitude change and achievement outcomes.
• The results demonstrated that attitude change could be produced through dissonance-inducing procedures, supporting the principles of cognitive dissonance theory.

IV. Learning Theories

A. Behavioral approach and stimulus characteristics

• Learning theories in attitude change, rooted in behavioral psychology, focus on the behavioral aspects of attitudes.
• These theories emphasize the influence of stimulus characteristics in the communication situation.
• Staat’s work reflects classical conditioning principles, where new stimuli become associated with old stimuli through consistent pairing, resulting in emotional responses.

B. Hovland and Yale Communication Research Program

• Hovland and his associates at the Yale Communication Research Program contributed significantly to learning theories of attitude change.
• They proposed that opinions tend to persist unless individuals undergo new learning experiences.
• Persuasive communications that present a question and suggest an answer serve as learning experiences to change attitudes.

C. Role of incentives and reinforcement in attitude change

• Hovland and his colleagues highlighted the importance of incentives and reinforcement in persuasive messages.
• Acceptance of new beliefs and attitudes is influenced by the opportunity for mental rehearsal or practice of the recommended attitudinal response.
• Incentives, including financial benefits or social acceptance, act as mechanisms for reinforcement, promoting acceptance of new attitudes.

D. Bem’s Skinnerian approach and external cues

• Bem’s approach aligns with Skinnerian principles, emphasizing the role of external cues and observable behaviors in attitude change.
• According to Bem, attitudes are learned through previous experiences with the environment.
• To change attitudes, external cues are used to reward or punish individuals, shaping their attitudes through associations with observable behaviors.

V. Social Judgment Theory

A. Perceptual distortion based on prior attitudes

• Social Judgment Theory focuses on how prior attitudes influence perceptual distortion when evaluating persuasive messages.
• Individuals tend to judge positions advocated in messages based on their own attitudes, resulting in a biased perception of the message content.
• Perceptions are influenced by the individual’s judgmental anchor, which is their own attitude on the topic.

B. Latitudes of acceptance, rejection, and noncommitment

• Social Judgment Theory introduces the concept of latitudes, which represent the range of positions on an attitudinal continuum.
• The latitude of acceptance includes positions that are relatively close to the individual’s own attitude and are more likely to be assimilated.
• The latitude of rejection includes positions that are far from the individual’s attitude and are more likely to be contrasted or rejected.
• The latitude of noncommitment represents positions that neither fall within acceptance nor rejection.

C. Assimilation and contrast effects

• Social Judgment Theory explains the processes of assimilation and contrast that occur when evaluating persuasive messages.
• Messages falling within the latitude of acceptance are more likely to be assimilated, leading to attitude change toward the advocated position.
• Messages falling within the latitude of rejection are more likely to be contrasted, resulting in less attitude change or even reinforcement of existing attitudes.

D. Criticisms and relevance in current research

• Social Judgment Theory has faced criticisms, particularly regarding the complexity of its principles and how they relate to each other.
• However, the theory’s emphasis on prior attitudes and perceptual distortions still holds relevance in current research.
• Researchers continue to incorporate social judgment principles as covariates and control variables in experimental designs.
• The theory provides insights into the role of attitudes in shaping judgments and can inform the design of persuasive messages in various contexts.

VI. Functional Theories

A. Attitudes serving different psychological needs

• Functional theories propose that attitudes serve various psychological needs and have different motivational bases.
• Attitudes fulfill specific functions for individuals, addressing their unique psychological needs.
• The functions attitudes serve can vary between individuals and in different contexts.

B. Katz’s four personality functions of attitudes

• Katz identified four primary personality functions of attitudes:
  1. Utilitarian function: Attitudes that serve instrumental purposes, aiming to gain rewards or avoid punishments.
  2. Knowledge function: Attitudes that provide a structured and meaningful view of the world, simplifying perceptions.
  3. Ego-defensive function: Attitudes that protect one’s self-concept by employing defense mechanisms against threats.
  4. Value-expressive function: Attitudes that express personal values and contribute to self-expression.

C. Matching change procedures to attitude functions

• Functional theories suggest that effective attitude change involves aligning change procedures with the specific function served by the attitude.
• Understanding the motivational basis of an attitude helps in designing strategies that create a disparity between the attitude and its function.
• By targeting the specific function, attitude change efforts can be more successful.

D. Kelman’s processes of compliance, identification, and internalization

• Kelman proposed three processes of opinion change:
  1. Compliance: Attitude change motivated by seeking a favorable reaction or approval from others, resulting in surface-level change.
  2. Identification: Attitude change occurring both publicly and privately, influenced by the relationship with the source but not dependent on the source’s presence.
  3. Internalization: Attitude change that becomes part of an individual’s value system, integrating the new attitude into their core beliefs.

VII. Other Theoretical Approaches

A. McGuire’s inoculation theory and resistance to change

• McGuire’s inoculation theory focuses on developing resistance to attitude change.
• Similar to biological inoculation, individuals are exposed to mild attacks on their beliefs to strengthen their resistance.
• By experiencing and defending against weak challenges, individuals develop immunity to stronger attacks on their belief systems.

B. Link between behavioral theories and cognitive themes

• There is a connection between earlier behavioral theories and more recent cognitive themes in attitude research.
• Behavioral theories, such as those developed by Hovland and his associates, emphasized the role of reinforcement, incentives, and external cues in attitude change.
• These theories laid the foundation for understanding the influence of motivation, attention, and comprehension on attitude change.
• The integration of cognitive processes in more recent theories has further enhanced our understanding of the complexities of attitude change.

VIII. Implications for Media and Persuasive Messages

A. The role of media as a tool in attitude change research

• In the context of attitude change research, media is seen as a methodological tool rather than the direct influencer of attitudes.
• Media serves as a platform for delivering persuasive messages and studying their effects on attitudes.
• The focus is on the messages and methods used within the media rather than the media itself as the primary driver of attitude change.

B. Considerations for designing persuasive messages

• Theories of attitude change provide guidance for designing effective persuasive messages.
• Understanding the functions attitudes serve and the motivational bases of attitudes can help tailor messages to match individual needs.
• Factors such as source characteristics, setting characteristics, and communication content elements should be considered in message design.
• Attention, comprehension, and acceptance play vital roles in message effectiveness, and the opportunity for mental rehearsal and incentives can enhance attitude change.
• Persuasive messages should also consider the principles of social judgment theory, accounting for individuals’ prior attitudes and their latitudes of acceptance and rejection.

IX. Conclusion

A. Summary of attitude change theories

• Attitude change theories discussed in this article can be categorized into four main categories: consistency theories, learning theories, social judgment theories, and functional theories.
• Consistency theories, such as balance theory and cognitive dissonance theory, emphasize the need for consistency between attitudes, behaviors, and beliefs.
