First study to demonstrate inconsistency between attitudes and behaviors
Reviewed literature and concluded no attitude-behavior consistency
3 main predictors of behavior?
Attitudes towards the behavior
Perceived behavioral control
When'd do attitudes predict behavior?
When situational pressures are minimized,
when attention is focused on the attitude,
when the attitude is formed by active experience,
when attitude is personally relevant, when the cognitive and effective components of attitude match,
when appropriate measures are used
cognitive dissonance theory
People want and need to be consistent, the theory that inconsistencies between a persons thoughts, sentiments and actions create and aversive emotional state(dissonance) that leaves to efforts to restore consistency
It appears that most of us are willing to sell our souls for money, and If the money is good enough, it doesn’t even seem necessary to justify the sale
Major assumptions of dissonance theory?
People have many pre-existing attitudes.
People prefer consistency among attitudes, beliefs, and behaviors
Inconsistency creates an aversive state of arousal
People may resolve the dissonance by changing their attitudes
people come to know their own attitudes by looking at their behavior and the context in which it occurred and inferring what their attitudes must be
major assumptions of self-perception theory?
People do not have lots of pre-existing attitudes.
Just like with other people, we infer our own attitudes by perceiving our own behavior
