Is personality written in your biology? Hans Eysenck believed so, and he spent decades building a scientific case for it.

In this episode, we explore Eysenck's biological theory of personality and his PEN model, covering the three dimensions of psychoticism, extraversion and neuroticism. We explain the biological basis of each dimension, including cortical arousal and limbic reactivity, the role of genetics and twin studies in personality research, and the Eysenck Personality Questionnaire.

Ideal for MRCPsych Part A revision, psychology students and anyone interested in the biological roots of personality. Aligned with the Royal College of Psychiatrists MRCPsych Part A syllabus, paragraph 1.1.6.

I would love to hear from you!
