Cognitive and affective matching effects in persuasion: an amplification perspective

Area of Science:

• Social Psychology
• Attitude Change
• Persuasion

Background:

• Cognitive and affective attitudes are typically more receptive to matched persuasive attacks.
• Attitude certainty is generally thought to reduce openness to change.
• The influence of attitude certainty on openness to matched vs. mismatched attacks requires further investigation.

Purpose of the Study:

• To investigate how attitude certainty influences openness to cognitive and affective persuasive attacks.
• To test the amplification hypothesis regarding attitude certainty and persuasion.

Main Methods:

• Two experiments were conducted to examine the relationship between attitude certainty and attitude change.
• Participants' attitudes were subjected to either matched or mismatched persuasive attacks.

Main Results:

• High attitude certainty amplified resistance to mismatched attacks.
• High attitude certainty increased openness to matched attacks, supporting the amplification hypothesis.
• Findings challenge the general assumption that certainty always reduces attitude openness.

Conclusions:

• Attitude certainty plays a dual role in persuasion, enhancing openness to matched appeals while bolstering resistance to mismatched ones.
• The findings have implications for strategies aimed at increasing attitude openness to diverse persuasive messages.
