What is the primary focus of the biological approach in psychology?

The primary focus of the biological approach in psychology is on biological systems and their relation to behavior. This perspective emphasizes how genetic, neurological, and physiological factors influence thoughts, emotions, and actions. By examining the role of the brain, neurotransmitters, hormones, and genetics, this approach seeks to understand how these physical components drive psychological functioning.

For instance, researchers may investigate how imbalances in neurotransmitters like serotonin can lead to mood disorders, or how structural brain abnormalities are associated with certain psychological conditions. This link between biology and behavior is foundational to the biological approach, contrasting significantly with perspectives focused on cognitive processes, social influences, or emotional responses.
