What is the focus of the biological approach in psychology?

The biological approach in psychology emphasizes understanding how biological processes, such as genetics, neurochemistry, and brain anatomy, influence behavior and mental processes. This perspective posits that many psychological phenomena can be traced back to physical causes within the body, including structures in the brain and various hormones and neurotransmitters that affect mood and behavior. Researchers may investigate how brain injuries, hormonal imbalances, or genetic predispositions contribute to conditions like depression, anxiety, or schizophrenia. By focusing on these biological underpinnings, this approach aims to provide a clearer understanding of the underlying mechanisms that drive behavior, distinguishing it from approaches that mainly consider social or cognitive factors.
