Which theory posits that personality is inherited and biologically based?

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

Answer: (D)

Biological theory argues that personality is inherited and rooted in biology. It suggests that genetic factors shape enduring traits and temperamental differences, with brain structure and neurochemical processes influencing how we think, feel, and behave. This view is supported by evidence from studies showing genetic influence on personality, including similarities in identical twins and patterns that persist across environments. It differs from trait theory, which describes stable patterns of behavior without pinpointing a biological source; social learning theory, which emphasizes learning from others and environmental cues; and interactionist theory, which highlights how biology and environment interact to shape personality.
