Final answer:
The biological approach to psychology focuses on the brain and its biological processes, combining the research strategies of psychologists and physiologists to understand how the nervous system generates behavior.
Step-by-step explanation:
The biological approach to psychology focuses on the brain and its biological processes, such as sensory and motor systems, sleep, drug use and abuse, ingestive behavior, reproductive behavior, neurodevelopment, plasticity of the nervous system, and biological correlates of psychological disorders. Biological psychologists combine the research strategies of both psychologists and physiologists to understand how the structure and function of the nervous system generate behavior. This interdisciplinary approach is often referred to as neuroscience.
