Source of the Communication

Expert and trustworthy.
Attractiveness.
Communicator argues against their own
self-interest.

not trying to influence them.

influenced.
Nature of the Communication





Compelled by fear – fear arousing with
specific instructions more likely to change
behavior. But – if behavior is too threatening,
avoided.
Statistics vs. personal examples – vivid
powerful
One-sided vs. two-sided arguments –
audience position and informed-ness
Order of presentation of arguments – primacy
and recency (next slide)
Relationship between credibility of
communicator, discrepancy of views with
audience, and persuasion.
Primacy and Recency Effects


Primacy
Most evident when statements are back to back
and behavior change follows a time gap
Recency
Most evident when enough time separates the
two messages and audience commits soon
after the second message.
Characteristics of the Audience

Self Esteem


Higher less persuadable, more likely to act
quickly in fear situation
Prior Experience

 Don’t want to be led around
 Counter arguments on the spot


Discrepant views, one or two sided
arguments.
Cognitive Dissonance and
Persuasion

If message of the communicator is inconsistent
with the audience, persuasion depends on…
Size of the discrepancy
 Communicator variables (trustworthiness – can the
communicator be changed or derided?)
 Other audience responses
 Innoculation/ability to develop arguments in
opposition

A few social influence tactics…

Requests

first to larger
 Door-in-the-Face – large request to
small
 That’s Not All! -- add incentives
