Which of the following is listed as a personality trait in trait theory?

• A. Ambition
• B. IQ
• C. Verbal fluency
• D. Well-groomed

Answer: (A)

In trait theory, personality is seen as a set of stable dispositions that guide how a person tends to think, feel, and behave across different situations. Ambition fits this idea because it is a consistent, enduring motivation to achieve, set goals, and strive for success. It reflects a trait-like tendency to take initiative and persist, which trait theory uses to explain regular patterns in behavior.

The other options represent different kinds of abilities or appearances rather than stable personality dispositions: IQ measures general cognitive ability, not a trait; verbal fluency is a specific language-related skill; and being well-groomed describes appearance or a situational presentation rather than a lasting characteristic of temperament.
