Studies of college students' conscientiousness revealed only a modest relationship between a student being conscientious on one occasion and being similarly conscientious on another occasion.This should make psychologists more cautious about overestimating the impact of ________ on behavior.

A) extraversion
B) personality traits
C) self-esteem
D) self-efficacy

The statement suggests that there is only a modest relationship between being conscientious on one occasion and being similarly conscientious on another occasion among college students. This implies that personality traits, such as conscientiousness, may not have as much impact on behavior as previously thought. Therefore, psychologists should be cautious about overestimating the impact of personality traits on behavior.
