Step 1: Understanding the Concept:
Attitudes are evaluations of people, objects, or ideas. Social psychologists describe attitudes as having several key properties or dimensions that determine their strength and impact.
Step 2: Detailed Explanation:
Let's examine the listed properties:
Valence: This refers to the direction of the attitude—whether it is positive, negative, or neutral. This is a fundamental property.
Centrality: This describes how important an attitude is to a person's overall value system. A central attitude is closely linked to one's core values and self-concept. This is a significant property.
Extremeness: This refers to how strong the valence is. An attitude can be slightly positive or extremely positive. This is also a significant property.
Quantity: This is not a recognized property of a single attitude. While a person has a "quantity" of different attitudes, the term itself doesn't describe a characteristic of any one attitude. Other properties include simplicity/complexity (how many beliefs make up the attitude).
Step 3: Final Answer:
Valence, Centrality, and Extremeness are all significant properties of attitude. Quantity is not.
