Under Hans Eysenck's Three-Factor Model of Personality (PEN Model), which includes the dimensions of Psychoticism, Extraversion, and Neuroticism, which of the following statements most accurately explains the biological basis and behavioral traits of Eysenck's theory?
✓ Correct! Well done.
✗ Not quite — the correct answer is highlighted above.
Detailed Explanation
Hans Eysenck formulated his famous 'PEN Model' using factor analysis in the study of personality. According to him, the biological basis of 'Extraversion' and 'Introversion' is linked to the functioning of the brain's Reticular Activating System (RAS) and cortical arousal.
Key Concepts:
- Extraversion: Characterized by lower baseline cortical arousal, leading individuals to seek external stimulation.
- Introversion: Characterized by higher baseline cortical arousal, leading individuals to avoid sensory overload.
Therefore, option A is the most accurate statement regarding the biological foundations of Eysenck's personality theory.
