World AIDS Day: Elaboration Likelihood Model Communication Theory 2009.12.01 Brad Gangnon

The Basics What is HIV? A virus that attacks the body’s immune system—the body’s defense against disease Are HIV and AIDS the same? No “Living with HIV”—virus in the body “Developed AIDS”—immune system too weak to fight off diseases

The Statistics People Living with HIV 33.4 million people living with HIV worldwide 31.3 million adults 15.7 million women 2.1 million children under 15 New HIV Cases in 2008 2.7 million people 2.3 million adults 430,000 children under 15

Routes to Persuasion (Griffen 194) Central Route Involves message elaboration Thinking about relevant arguments Peripheral Route Processing without careful thought Relies on Short Cuts

6 Peripheral Cues for Decision Making Reciprocation Consistency Social Proof Scarcity Liking Authority (Griffen 194)

Cognitive Processing The 2 routes are poles on a continuum Model demonstrates mental effort Higher listener effort lower effect of irrelevant factors Higher number of irrelevant factors lower persuasive effect

Worth the Effort (Griffen 195-6) We cannot elaborate all arguments Central Route Issues that are personally important or relevant Peripheral Route Issues that are NOT personally important or relevant High Need for Cognitive Clarity Almost all issues elaborated, use central route

World AIDS Day: Worth the Effort? Is AIDS/HIV important in our lives? Number of people with AIDS/HIV Worldwide 33.4 Million Number of People in Guangzhou 9.6 Million Number of People in Zhuhai 1.2 Million Number of People in Hong Kong 7.0 Million

World AIDS Day: Worth the Effort? 2 New HIV Cases in 2008 2.7 Million This means There were 2+ New HIV Cases per person in Zhuhai For every 2.5 people in Hong Kong, 1 new HIV Case For every 3.5 people in Guangzhou, 1 new HIV Case

Elaboration (Griffen 196) Distraction Disrupts elaboration Repetition May increase the elaboration How did the last two slides use repetition?

2 Types of Elaboration (p. 197) Biased Elaboration Top Down Elaboration Predetermined conclusions meet data Objective Elaboration Bottoms Up Elaboration Considers data on its own merits

Peripheral Attitude change without elaboration 6 Peripheral Cues Reciprocation Consistency Social Proof Scarcity Liking Authority

Mary Fisher : “ A Whisper of AIDS ” Later, we will return to the elaborated parts of Fisher’s speech How does Fisher use peripheral cues?

Reciprocation “ You owe me” “ Tonight, I represent an AIDS community whose members have been reluctantly drafted from every segment of American society. Though I am white and a mother, I am one with a black infant struggling with tubes in a Philadelphia hospital. Though I am female and contracted this disease in marriage, and enjoy the warm support of my family, I am one with the lonely gay man sheltering a flickering candle from the cold wind of his family 's rejection. ”

Consistency “ We ha ve always done it that way” “ But we do the President's cause no good if we praise the American family but ignore a virus that destroys it. We must be consistent if we are to b e believed. We cannot love justice and ignore prejudice, love our children and fear to teach them. Whatever our role, as parent or policy maker, we must act as eloquently as we speak-else we have no integrity. ”

Social Proof “ Everybody’s doing it” “ My family has been a rock of support. My 84-year-old father, who has pursued the healing of the nations, will not accept the premise that he cannot heal his daughter. My mother has refused to be broken; she still calls at mid-night to tell wonderful jokes that make me laugh. Sisters and friends, and my brother Phillip (whose birthday is today)-all have helped carry me over the hardest places. I am blessed, richly and deeply blessed, to have such a family.”

Liking “ Love me, love my ideas” “ I want my children to know that their mother was not a victim. She was a messenger. I do not want them to think, as I once did, that courage is the absence of fear; I want them to know that courage is the strength to act wisely when most we are afraid. I want them to have the courage to step forward when called by their nation, or their Party, and give leadership-no matter what the personal cost. I ask no more of you than I ask of myself, or of my children. ”

Authority “ Just because I say so” “ My call to you, my Party, is to take a public stand no less compassionate than that of the President and Mrs. Bush. ” “ My father has devoted much of his lifetime to guarding against another holocaust. He is part of the generation who heard Pastor Niemoeller come out of the Nazi death camps to say, "They came after the Jews and I was not a Jew, so I did not protest. They came after the Trade Unionists, and I was not a Trade Unionist, so I did not protest. They came after the Roman Catholics, and I was not a Roman Catholic, so I did not protest. Then they came after me, and there was no one left to protest.“”

Scarcity “ Quick before they’re all gone” “ I will not hurry to leave you, my children. But when I go, I pray that you will not suffer shame on my account. “

Source Credibility (p. 198) Source credibility important peripheral cue 2 Components Likability Expertise (form of AUTHORITY) 2 Contexts where Valuable U nmotivated audience Unable to elaborate

Limits of Source Credibility Penner and Fritzshe’s study of Magic Johnson’s HIV announcement suggests that the effect of even powerful peripheral cues is short-lived. Although most ELM research has measured the effects of peripheral cues by studying credibility, a speaker’s competence or character could also be a stimulus to effortful message elaboration.

Aristotle and the Enthymeme (p. 281) An incomplete version of a formal deductive syllogism Unstated premise Unstated conclusion Syllogism Major premise: All people are created equal Minor premise: I am a person Conclusion: I am equal to other people

Active Audience Moments “ I would never have asked to be HIV-positive. But I believe that in all things there is a good purpose, and so I stand before you and before the nation, gladly. ” Allusion to Ecclesiastes 3.1 “To everything there is a season, and a time to every purpose under heaven”

Discussion Questions Is a panel on the Names Project/AIDS memorial quilt a central or peripheral cue? Is an enthymeme a part of an elaborated argument? Why does World AIDS Day create a good opportunity to discuss ELM?
