What best describes the focus of the biological perspective in psychology?

The biological perspective in psychology emphasizes that behavior is significantly influenced by genetics and neurobiology. This perspective posits that the physiological processes within the body, including brain structure, neurotransmitter function, and genetic predispositions, all play crucial roles in shaping how we think, feel, and behave.

Research in this area often examines how various biological factors, such as hormones, brain chemistry, and heredity, contribute to psychological phenomena. For instance, studies might look at how imbalances in neurotransmitters can affect mood or how genetic variations can predispose individuals to certain psychological conditions.

This focus on biology helps to establish a scientific basis for understanding behaviors and mental processes, integrating findings from fields such as neuroscience, genetics, and evolutionary psychology. Thus, option C encapsulates the essence of the biological perspective by highlighting the roles of genetic makeup and neurobiological processes in determining behavior.
