Theory of Personality (D564) Practice Exam

According to Eysenck's trait theory of personality, what is the second dimension alongside introversion-extraversion?

1. Openness

2. Neuroticism

3. Agreeableness

4. Conscientiousness

The correct answer is: Neuroticism

In Eysenck's trait theory of personality, the second dimension alongside introversion-extraversion is neuroticism. This dimension refers to emotional stability and the tendency of an individual to experience negative emotions such as anxiety, depression, and moodiness. People who score high on neuroticism are more likely to experience these negative emotions frequently and intensely, whereas those who score low tend to be more emotionally stable and resilient. Eysenck proposed that these two dimensions—introversion-extraversion and neuroticism—together create a more comprehensive picture of an individual's personality. While introversion-extraversion focuses on how individuals relate to their social environment, neuroticism reflects how they manage and react to their internal emotional states. This combination allows for a more nuanced understanding of personality traits and how they manifest in behavior. The other choices, although significant in their own right, do not fall within the framework established by Eysenck. Openness, agreeableness, and conscientiousness are part of the Five Factor Model or Big Five personality traits, which is different from Eysenck's two-dimensional theory.
