Answer:Eysenck's theory of personality

Explanation:Hans Eysenck's PEN model of personality

Neuroticism vs. Emotional stability

Psychoticism vs. Normality

Eysenck held a belief thatt biological factors (i. e hormonal level) works along with environmental factors (learned behavior) all contribute to the personalities.
