Which field studies how biology influences behavior and mental processes?

• A. Social Psychology
• B. Developmental Psychology
• C. Cognitive Psychology
• D. Neuropsychology

Answer: (D)

Biology's impact on behavior and thinking is the focus here, and neuropsychology specifically examines that link. This field asks how brain structures and neural processes shape the way we think and act, and what happens to behavior when the brain is damaged or altered. Researchers map functions to brain regions using brain imaging, neuropsychological testing, and observations of individuals with brain injuries to understand how biology underpins mental processes and behavior. This biological emphasis distinguishes neuropsychology from other areas: social psychology looks at how others influence thoughts and actions, developmental psychology tracks changes across the lifespan, and cognitive psychology studies mental processes themselves (often without focusing on their neural bases).
