  1. Gass & Seiter Model • Pure persuasion: • is intentional • is effective or successful • is noncoercive • relies on language and symbolic action • involves two or more persons • Borderline persuasion • is missing one or more of these litmus tests

  2. Elaboration Likelihood model (ELM) • Two basic routes to persuasion: Central and Peripheral • They represent the ends of an “elaboration continuum” • They represent qualitatively different modes of information processing

  3. Illustration of the ELM • The Central route is reflective, requires mental effort, and relies on cognitive elaboration • Motivation (willingness) to process a message • Ability to process (understand) a message Example: Lulu is car shopping She looks up information comparing safety, reliability, performance, customer satisfaction, mileage, and depreciation for three makes of sporty cars She scrutinizes the information carefully before making a decision

  4. Illustration of the ELM • Example: A Christian homeowner hires a plumber because the plumber’s ad in the Yellow Pages includes an ichthys symbol (sign of the fish) • The Peripheral route is reflexive, based on mental shortcuts: • credibility, appearance cues, quantity of arguments • heuristic cues (decision rules): rules for simplifying the thought process

  5. Peripheral cues • Peripheral cues • Celebrity endorsers • “As seen on TV” • “Always tip 18%” • “It’s your watch that says the most about you” (slogan for Seiko watches) • “Shoes make the man” • The role of involvement • High involvement increases the likelihood of central processing • Low involvement increases the likelihood of peripheral processing • High involvement decreases reliance on credibility (peripheral cue)

  6. Alcohol Ads & Peripheral Processing • American children view 2,000 beer and wine commercials per year (American Academy of Pediatrics, 1995). • Beer advertisements are a significant predictor of adolescent preference for beer brands (Gentile, 2001). • 56% of students in grades 5-12 say that alcohol advertising encourages them to drink (American Academy of Pediatrics, 2001).

  7. Which ad relies on peripheral processing?

  8. Central or peripheral processing?

  9. Central or peripheral processing?

  10. Central or peripheral processing?

  11. Persistance of persuasion • Persuasion that takes place via the central route tends to be more lasting • Persuasion that takes via the peripheral route tends to be more transitory

  12. Heuristic-systematic model (HSM) • Bears many similarities to the ELM • Two basic routes or modes of information processing • Systematic processing is more thoughtful, deliberate, analytical • Analogous to “central” processing in the ELM • Heuristic processing is more reflexive, automatic • Analogous to “peripheral” processing in the ELM • Relies on decision rules, e.g., “Never pay retail,” “Buy low, sell high” • Decision rules are activated under the appropriate circumstances

  13. Systematic processing ads

  14. Heuristic cues • Motivation and ability to process a message are key determinants • Sufficiency principle: people don’t want to spend too much or too little time/effort making a decision • HSM allows for the possibility of simultaneous processing (both systematic and heuristic) • Must Be: • Available: stored in memory for potential use • Accessible: activated from memory • Applicable: related to the receiver’s goals or objectives

  15. Heuristic processing in Rx Drug ads • A majority of ads for pharmaceutical manufacturers rely on emotional appeals to attract consumers. • A study of 122 ads by pharmaceutical manufacturers revealed that 62% relied on emotional appeals, such as hope, fear, or sympathy (Annals of Internal Medicine)

  16. Heuristic or systematic processing?

  17. Theory of Reasoned Action (TRA) Adapted from Ajzen, I., & Fishbein, M. (1980). Understanding attitudes and predicting social behavior. Englewood Cliffs, NJ: Prentice Hall.

  18. Illustration of the TRA • Ned has begun drinking heavily since he started college • Attitude toward the behavior: “I think drinking is ruining my health and it caused me to get fired from my job.” • Subjective Norm component: “I know my friends and family would like me to stop drinking.” • Intention: “I intend to stop drinking altogether.” • Behavior: Ned attends his first AA meeting the next day

  19. Theory of Planned Behavior (tpB) • An extension of the TRA • The TpB adds the additional element of perceived behavioral control (self-efficacy) • Internal factors might prevent or reduce control (lack of knowledge, lack of skill) • External factors might prevent or reduce control (limited time or resources) • Intentions correlate more strongly with actual behavior when there is perceived behavioral control
