Persuasion
Historically interesting attempts to
persuade based on psychological theories:
1) motivational
research
2) subliminal stimulation
3) brainwashing
Motivational
Research - attempts to use
psychoanalytic concepts in ad
campaigns; what are the motives for buying (consumer behavior)
Vance Packard - “The Hidden Persuaders” (1957) surveyed the use of mass
psychoanalysis in ads.
Subliminal Stimulation - our senses measure more than we
consciously perceive, so whatever doesn’t get to us on the conscious level may
hit us unconsciously (just on the threshold of perception);
Brainwashing - relies on brute force and creation of emotional
dependency on the brainwasher (the brainwasher becomes the sole source of every
satisfaction); debility,
dependency, dread (abuse, fatigue, isolation); returning victim to an earlier
childlike state of total dependency making his attitudes non-functional and new
attitudes more functional; dissonance
reduction
Newscasting - what they decide to report can influence our opinions
Education - education or propaganda - think of examples that are
used
Elaboration
Liklihood Model (Petty & Cacioppo, 1986)
Two
routes to persuasion: central (think about the issue) and peripheral (little
thought, surface characteristics focus)
Chaiken (1980) half of
the Ss expected to be interviewed on aa topic (religion in the public schools);
half did not. For Ss in the expectancy condition _______________
most affected their attitudes; for Ss in the non-expectancy condition __________________ most affected their attitudes
Petty & Cacioppo -
manipulated the number of arguments (3, 6, 12) and the personal relevance of
the issue (high or low). Under
_________ condition would the number of arguments be effective.
Heuristic Model of
Persuasion (Chaiken, 1987) when a situation is personally involving systematic
processing of input occurs; when involvement is low heuristic processing occurs
(such as ?)
Eagly (1967) presented Ss with
information about themselves or about others. The info was discrepant in either
a favorable or unfavorable direction from initial attitudes. Which people
changed the most? Why?
Hovland - A
Situational approach to persuasion
In learning new attitudes 3
variables are important: attention, comprehension, acceptance
4 variables in communication: the
source (who says it); the nature of the communication (how it is said); the
audience (who it is said to)
The Source - expertise,
trustworthiness, personal attractiveness (physical appeal), similarity, power
over the recipient
An
attributional analysis (Eagly, Chaiken, Wood, 1978) knowledge bias - expectations about the position the source will
take; reporting bias - expectation that the source may be unwilling to
communicate accurate info.
The content - primacy-recency
issues; strawman , forewarning, and inoculation; logical vs. emotional appeals
The audience - fantasy ability,
self-esteem, education level
