The Peripheral Model: Examples and Applications Across Disciplines

The peripheral route to persuasion, a cornerstone of the Elaboration Likelihood Model (ELM) of persuasion, posits that attitude change can occur without extensive cognitive processing. Unlike the central route, which involves careful consideration of message content, the peripheral route relies on superficial cues and heuristics to influence attitudes. Understanding this model is crucial for anyone involved in communication, marketing, advertising, or even interpersonal relationships. This article will explore the peripheral route with diverse examples, highlighting its strengths and limitations.

Understanding the Peripheral Route:

The ELM, developed by Richard Petty and John Cacioppo, proposes two distinct routes to persuasion: central and peripheral. The central route involves thoughtful consideration of message arguments, requiring motivation and cognitive capacity. The peripheral route, however, shortcuts this process. Persuasion occurs through cues that are peripheral to the message's content, such as the attractiveness of the source, the length of the message, or the presence of positive emotional cues. These cues trigger automatic responses, leading to attitude change without deep engagement with the message itself.

Key Peripheral Cues:

Several factors can act as peripheral cues, influencing persuasion through the peripheral route. These include:

• Source Credibility: A message delivered by a trusted or expert source is more likely to be accepted, even without critical evaluation of the message's content. Think of celebrity endorsements – we often buy a product based on who's recommending it, not necessarily on detailed product specifications.

• Source Attractiveness: Physically attractive or likable sources can influence attitudes positively, regardless of message quality. This is often seen in advertising, where beautiful models are used to promote products.

• Message Length: A longer message might be perceived as more credible or comprehensive, leading to acceptance even if the arguments within are weak. This is a heuristic – "longer must be better."

• Emotional Appeals: Messages evoking positive emotions (joy, happiness) or fear can persuade without rational deliberation. Fear-based advertising, like those highlighting the dangers of smoking, often employs this strategy.

• Number of Arguments: Presenting a large number of arguments, even if weak, can overwhelm critical thinking, leading to acceptance. This is similar to the "length" effect, playing on the heuristic of quantity implying quality.

• Consensus: The perception that many people agree with a particular viewpoint can lead to conformity and attitude change, regardless of individual assessment. Bandwagon effects in marketing utilize this principle.

Examples of the Peripheral Route in Action:

Let's explore diverse examples illustrating the peripheral route's influence:

• Advertising: A perfume commercial featuring a beautiful celebrity in a romantic setting doesn't focus on the scent's chemical composition. Instead, it uses the celebrity's attractiveness and the emotional appeal of romance to persuade viewers.

• Political Campaigns: Candidates often employ slogans and jingles that are catchy and emotionally resonant, rather than relying on detailed policy explanations. The candidate's appearance, charisma, and endorsements also play a key role.

• Sales Techniques: High-pressure sales tactics, such as limited-time offers or scarcity appeals ("only two left!"), manipulate the peripheral route by creating urgency and triggering impulsive decisions.

• Social Influence: Conformity to group norms, even when those norms are illogical, demonstrates the power of social cues on attitude change. Asch's conformity experiments are classic examples.

• Health Campaigns: Public service announcements using fear appeals (e.g., showing graphic images of the consequences of smoking) can be effective, even without providing detailed information about cessation programs.

Limitations of the Peripheral Route:

While effective in the short term, persuasion through the peripheral route often lacks durability. Attitude changes are more susceptible to counter-persuasion and less likely to predict behavior compared to those resulting from the central route. The reliance on superficial cues means that the attitude shift may be shallow and easily reversed. Furthermore, ethical concerns arise when manipulative techniques are employed to exploit the peripheral route.

The Interplay Between Central and Peripheral Routes:

It's essential to note that the central and peripheral routes are not mutually exclusive. Often, both routes operate simultaneously, with their relative influence depending on individual factors like motivation and ability, as well as message characteristics. A highly engaging message might trigger both central and peripheral processing, leading to a stronger and more enduring attitude change.

Conclusion:

The peripheral route to persuasion offers a valuable framework for understanding how attitudes can change without extensive cognitive effort. Recognizing the role of peripheral cues in influencing our judgments and decisions is crucial for critical thinking and navigating the persuasive messages that constantly surround us. While effective in specific contexts, reliance on the peripheral route for long-term attitude change is limited. Understanding the nuances of both central and peripheral routes empowers us to become more discerning consumers of information and more effective communicators ourselves. By understanding how peripheral cues operate, we can both utilize them ethically and defend ourselves against manipulative uses of this powerful persuasive technique.
