According to Hans Eysenck's Hierarchical and Dimensional Trait Theory of Personality, the dimensions of 'Introversion-Extraversion', 'Neuroticism-Stability', and 'Psychoticism' have deep physiological and biological bases. If an individual experiences rapid fatigue from external stimuli due to high levels of cortical arousal in the central nervous system, avoids social interactions, and exhibits introversion combined with high neuroticism according to Eysenck's three-factor model, which of the following statements is most authentic and scientifically true regarding this psychological and biological profile?

Detailed Explanation

According to Hans Eysenck's personality theory, introverted individuals naturally possess a higher baseline level of cortical arousal in their brains. Consequently, they easily become overstimulated by external environmental inputs and prefer quieter environments and less social interaction to keep their arousal levels manageable. Conversely, extraverts have lower baseline arousal levels and seek out external stimulation.

• Option C accurately reflects this biological mechanism by linking introversion to high cortical arousal and reduced desire for intense social engagement.
• Options A, B, and D contain scientifically incorrect assertions regarding Eysenck's biological trait model.
