Research suggest that people who are high in the personality trait of openness tended to be more mentally flexible and verbally fluent and more likely to take creative, unconventional approaches to solving problems. Extraverted people were also more likely to score higher on test of verbal fluency because they tended to talk more, and be less concerned about mistakes. And people higher in the trait of conscientiousness tend to perform better on memory tasks because they’re generally better organized and willing to work harder.
