Final answer:
Ben's characteristics suggest he would be rated low on the factor of emotional stability, which aligns with experiencing negative emotions and being anxious and unhappy.
Step-by-step explanation:
If Ben is tense, nervous, depressed, and insecure, he would tend to be rated as low on emotional stability. This factor is one of the Big Five personality factors, representing the range between stability and neuroticism. Emotional stability is characterized by being calm and even-tempered, while the opposite end is neuroticism, which includes traits like anxiety and emotional instability. According to the Eysenck's theory, individuals high on neuroticism, which corresponds to being low on emotional stability, often experience negative emotions such as anxiety and unhappiness. Thus, Ben's described characteristics suggest a lower score in emotional stability.
