Which principle is emphasized in the biological approach to psychology?

The biological approach to psychology emphasizes the impact of genetics and physiological processes, focusing on how these biological factors influence behavior and mental processes. This perspective examines how brain structure, neurotransmitters, hormones, and inherited traits shape our actions, thoughts, and emotions. It is grounded in the idea that psychological phenomena can be understood through biological foundations, which often include genetic predispositions, the functioning of the nervous system, and the overall health of the body.

Understanding behavior from this angle involves looking at how biological processes, such as those involving the brain and endocrine systems, directly affect our psychological experiences. For example, studies may explore how genetic variations can contribute to the likelihood of developing certain psychological conditions or how imbalances in brain chemistry can lead to mood disorders.

The other principles presented in the choices all pertain to different approaches to understanding psychology. For instance, the influence of environmental factors pertains more to behavioral and social approaches, while social relationships focus on interpersonal aspects relevant to social psychology. The importance of cognitive processes is associated with cognitive psychology, which studies internal mental processes like thought and problem-solving. Each of these perspectives highlights valuable aspects of human behavior but does not prioritize the core biological factors emphasized in the biological approach.
