Aging And End-of-Life Concepts Practice Test

Which term describes the theoretical model identifying Openness, Conscientiousness, Extraversion as components?

Openness Costa and McCrae's Big Five traits Extraversion Formal education

Correct Answer:

Costa and McCrae's Big Five traits

Explanation:

The main idea here is the Big Five personality model, also known as the Five-Factor Model. This framework describes five broad personality dimensions, including Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. The term that names the theoretical model linking Openness, Conscientiousness, and Extraversion (along with the other two dimensions) and credits the researchers who popularized it is Costa and McCrae's Big Five traits. Using this phrasing directly points to the established model itself, not to any single trait. The other options don’t fit because Openness and Extraversion are individual dimensions, not the overall model, and Formal education has no relation to this personality framework.
