Which branch of psychology links biological processes with behavior?

Biological psychology, also known as biopsychology or psychobiology, focuses on understanding how biological processes, such as genetics, neurochemistry, and brain structures, influence behaviors, thoughts, and emotions. This branch of psychology seeks to explore the connections between the physiological systems of the body and the mental processes and behaviors that result from them.

For example, biological psychologists may study how neurotransmitters affect mood or how brain injuries can alter behavior. They utilize various techniques, including neuroimaging and biochemical assessments, to gather data on how biological factors interplay with psychological phenomena. This approach provides valuable insights into mental health conditions and promotes a better understanding of how biological factors can inform treatment and interventions.

In contrast, developmental psychology focuses on the growth and changes that occur throughout a person's lifespan. Cognitive psychology is concerned with understanding mental processes such as perception, memory, and problem-solving, while behavioral psychology emphasizes observable behaviors and the ways they can be modified through various forms of conditioning. Each of these areas has its unique focus, but biological psychology specifically examines the biological underpinnings of behavior, making it the correct choice for this question.
