The statement refers to the feature of attitude called extremeness.

Extremeness is the degree to which a person holds a particular attitude. It is measured by the distance between the person's attitude and the neutral point on a scale.

In the statement, the person is asked to rate their liking for dogs on a scale of 1 to 10, where 1 is the least and 10 is the most. This is a measure of the person's extremeness of attitude towards dogs.

A person who rates their liking for dogs as a 10 has a more extreme attitude than a person who rates their liking for dogs as a 5.

The other options are not as relevant:

• Predictability: Predictability refers to the likelihood that a person will behave in a certain way based on their attitude.
• Simplicity: Simplicity refers to the clarity and coherence of a person's attitude.
• Centrality: Centrality refers to the importance of an attitude to a person's overall belief system.

Therefore, the correct answer is extremeness.
