Final answer:
The student scored high on 'openness to experience' due to her originality, imagination, and artistic qualities, and 'neuroticism' due to her tendencies toward insecurity, anxiety, and guilt.
Step-by-step explanation:
A classmate's test results indicating she is original, imaginative, and artistic suggest that she scored high on the openness to experience factor of the Five-Factor Model (FFM). This personality trait is characterized by a high degree of imagination, feelings, actions, and ideas. Individuals with high scores in this area tend to be curious and have a wide range of interests.
Moreover, since the results also showed she is prone to insecurity, anxiety, and guilt, it indicates that she scored high on the neuroticism factor. Neuroticism is marked by the tendency to experience negative emotions such as anger, impulsiveness, and hostility. High scores in neuroticism are often linked with emotional instability and characteristics such as anxiety and unhappiness.
