Which statement best reflects the core claim of the biological approach?

• A. Psychological processes can be explained without biology
• B. All behavior has biological bases
• C. Only social factors matter
• D. Only conscious thought matters

Answer: (B)

The biological approach holds that physiology underlies behavior and mental processes—brain structures and activity, neurotransmitters, hormones, and genetics shape how we think, feel, and act. Because of this emphasis, the statement that all behavior has biological bases best captures the approach’s view: it says that biology underpins every aspect of behavior and experience. The other options conflict with this perspective: thinking psychology can be explained without biology ignores the central role of the body in producing mental processes; focusing only on social factors downplays the biological mechanisms the approach highlights; and insisting that only conscious thought matters neglects how brain biology supports and even constrains those thoughts.
