Which branch of psychology links biological processes with behavior?

Biological psychology is the branch of psychology that specifically examines the relationship between biological processes and behavior. This field investigates how the brain, neurotransmitters, hormones, and genetics influence actions, thoughts, and feelings. By understanding these connections, researchers and practitioners can better grasp how various biological factors contribute to psychological phenomena.

The focus of biological psychology is grounded in the premise that behavior is not solely the product of environmental and social factors but is also significantly affected by physiological processes. This multidisciplinary approach often incorporates insights from areas such as neuroscience, psychiatry, and genetics, allowing for a comprehensive understanding of mental health issues and behaviors.

Other branches of psychology, such as developmental, clinical, and social psychology, each address different aspects of human experience. Developmental psychology looks at how individuals grow and change over their lifespan, clinical psychology primarily deals with diagnosing and treating mental disorders, and social psychology explores how individuals interact with one another and how group dynamics influence behavior. While these areas may touch on biological aspects, they do not focus on the direct link between biological processes and behavior in the same way that biological psychology does.
