Which theory suggests personality has a biological basis from inherited factors?

• A. Biological theory
• B. Trait theory
• C. Social learning theory
• D. Humanistic theory

Answer: (A)

Biological theory posits that personality has a biological basis from inherited factors, meaning genetic makeup and brain chemistry shape our temperament and traits. It argues that inherited differences in brain structure and neurochemical activity contribute to consistent patterns of thinking, feeling, and behaving. Twin and family studies show that similarities in personality correlate with genetic relatedness, supporting heredity's role, and research links certain brain systems to trait tendencies. Other approaches focus on learning from the environment or on personal growth and subjective experience, rather than inherited biology, so they don’t attribute personality to biology in the same way.
