Final answer:
With increasing age, the trait of neuroticism tends to decline slightly.
Step-by-step explanation:
As people age, the trait of neuroticism tends to decline slightly.
Neuroticism is the tendency to experience negative emotions, such as anger, impulsiveness, and hostility. People high on neuroticism tend to have emotional instability and feel anxious and unhappy.
Research has shown that the Big Five personality factor of neuroticism tends to decrease with age, along with extroversion, while factors like conscientiousness and agreeableness tend to increase.
