Final answer:
The traits of anxiousness, insecurity, and self-pity displayed by Stella align with neuroticism, which is one of the "big five" factors of personality. Neuroticism involves experiencing negative emotions such as anxiety and unrest, which fits Stella's characteristics.
Step-by-step explanation:
Stella exhibits traits such as anxiousness, insecurity, and often feeling sorry for herself, which best aligns with the neuroticism factor from the "big five" factors of personality. The correct answer is c. Neuroticism.
The Five Factor Model of personality, often remembered with the mnemonic OCEAN, includes openness to experience, conscientiousness, extroversion, agreeableness, and neuroticism. Neuroticism is characterized by a tendency to experience negative emotions such as anger, anxiety, and impulsiveness. People scoring high in neuroticism are often seen as emotionally unstable and may experience feelings of unhappiness and distress frequently. In contrast, those low in neuroticism tend to be calm and emotionally stable.
Stella's personality traits hint at a higher level of neuroticism as she deals with frequent anxiousness and insecurity. Therefore, her behavior is best explained by the neuroticism factor in the Big Five personality traits.
