Final answer:
A person who struggles with being calm and satisfied typically scores high on neuroticism in the Five-Factor Model of personality, which represents the tendency towards emotional instability and negative emotions.
Step-by-step explanation:
Neuroticism according:
The person described in the question is likely to rate high on B. neuroticism according to the Five-Factor Model of personality. Neuroticism, one of the traits in the Five-Factor Model, is largely about emotional stability and the propensity for negative emotions. People with high levels of neuroticism often experience feelings of anxiety, anger, and emotional instability.
They may have trouble staying calm and satisfied with themselves or others. This contrasts with other traits in the model such as openness (creativity and curiosity), conscientiousness (goal-directed behavior and reliability), agreeableness (cooperation and kindness), and extraversion (sociability and assertiveness), which describe other dimensions of a person's personality. The Five-Factor Model, or 'Big Five' as it is often called, provides a comprehensive framework for understanding these personality dimensions.
