PSY220 - 7. Attitudes & Persuasion Flashcards
What is an attitude?: tricomponent approach (Breckler, 1984)
i. affective reaction – evaluative reactions (positive/negative)
ii. behavioural reaction – can be independent of affective response (reinforcement), behavioural inclination - habit
iii. cognitive reaction – relevant beliefs activated by object
A + C often work in opposite ways
What is an attitude?: single-component approach (e.g., Eagly & Chaiken, 1993)
not sufficient to represent using only positive/negative dimension
mentally rank on positive dimension + simultaneously on negative dimension
can be both highly positive + negative
According to recent evidence…when we consider our attitude toward something (an attitude object) we consider where the object falls on
a) positivity + negativity dimension
When object has high positively, low negative = positive
High negative, low positive = negative
According to recent evidence…when we consider our attitude toward something (an attitude object) we consider where the object falls on
Ambivalent – approach-avoidance conflict, both forces pulling strongly: Oscillating behaviour
Indifference – low positive + negative
Static behaviour
Diff observable behaviour
According to recent evidence…when we consider our attitude toward something (an attitude object) we consider where the object falls on
Negativity dimension
Lo Hi
Positivity Hi Positive attitude Ambivalent attitude
Dimension
Lo Indifference Negative attitude
How can attitudes be measured? Self-report: Pros
- Convenient, cheap
- Easy
- Often “good enough” is all you need
How can attitudes be measured? Self-report
losses in precision
1. slight changes in wording can lead to extremely diff results
unaware of how accessibility (priming) can shape their attitude preceeding questions can change responses to subsequent questions
How can attitudes be measured? Self-report: Cons
- may give socially desirable response
bogus pipeline - routinized to give most political correct response – hooked up to fake lie detector machine, responses are more extreme
Likert scale
list of statements about an attitude object + asked to indicate on a multiple-point scale how much they agree/disagree with each statement
Suppelement with cover measures
Covert measures
immune to political correctness measures, largely out of participants’ control
1.physiological measure: minute changes in facial muscles, linked with emotional states, heart rate
don’t know where to attribute arousal
Brain wave increased when negative picture presented after string of positive pictures
Strength of spike reflect strength of attitude
Covert measures
- unconscious accessibility-based measures (IAT, the Fazio technique)
IAT: Measure attitudes toward anything
Speed at which you associate things with positive/negative
Fazio works with similar principle
What’s the relationship between our attitudes and our behavior?
Correlations betw behaviour + attitude disappointing to modest
Not a good predictor of corresponding behaviour
Fishbein & Ajzen: Theory of Planned Behavior: The relationship between attitude and behavior placed in broader context.
- attitude toward behavior
- social norms
- perceived control over behavior
Do what extent does your attitude toward tutoring high school kids translate into behavior?
take into account social norms, practical constraints, when all 3 info available then you can determine behavioural intentions that predicts strongly the actual behaviour
What predicts when an attitude will have a strong vs. weak influence on behavior?
A. Attitude strength
a) importance
1) directly affects own outcomes and self-interests
2) related to deeply held philosophical, political + religious values – prolife consistent with religious values
3) of concern to close friends, family, and social ingroups
What predicts when an attitude will have a strong vs. weak influence on behavior?
A. Attitude strength
b) accessibility
1) more you think about a topic, stronger attitude becomes, thoughts not often critical, more easily activated
What predicts when an attitude will have a strong vs. weak influence on behavior?
A. Attitude strength
2) self-awareness (Gibbons: “mirror study”) – political attitude questionnaire – half there’s a mirror – exhibited stronger correlation betw attitude + behaviour (more likely to sign up for political club). Arouses discrepencies – what I am + where I want to be – opportunities to solve discrepancies. Raises awareness for discrepancies between attitude + behaviour
What makes an appeal persuasive?
Measure attitude at time 1 + 2 – significant change = persuasion
1940’s & 50’s: Hovland et al.
1) learning of message contents
2) acceptance
WWII + Coldwar – interested in military propaganda
Persuaded only to arguments that they attend to, comprehend, remember
The Elaboration-Likelihood Model (ELM)
a) dual-process model:
i. central route (controlled, systematic processing of message’s arguments) – requires cognitive resources
ii. peripheral route (automatic, “quick and dirty” processing of message’s surface features)
The Elaboration-Likelihood Model (ELM)
Peripheral: often works via use of heuristics (“experts can be trusted,” “attractive people can be trusted,” “if there’s science, it must be good”)
Superbowl – likely drunk – Try to pursuade viewer through positive associations
Source variable #1: likeability
- students recruited to get other students to sign a petition to get the university to stop serving meat in cafeterias.
- petitioners gave strong reasons.
- varied was the physical attractiveness of the petitioners (both attractive and unattractive males and females).
Source variable #1: likeability
Results: Attractive petitioner Unattractive petitioner
41% signed > 32% signed
Source variable #2: personal involvement
No relevance – take things at face value
- speaker proposing that seniors should be required to take comprehensive exams in order to graduate.
- ½ told that speaker was an education professor at Princeton University, ½ told speaker was high school student
