What is the psychological perspective that emphasizes the role of biological factors in behavior?

The psychological perspective that emphasizes the role of biological factors in behavior is Biopsychology. This approach examines how biological processes, such as genetic predispositions, neurochemistry, and the functioning of the brain, influence thoughts, feelings, and actions. It recognizes that human behavior cannot be fully understood without considering the biological underpinnings, making it essential for understanding mental health, emotions, and personality from a scientific viewpoint.

By focusing on aspects like the nervous system, endocrine system, and the interactions between biology and environment, Biopsychology provides insights into how physical states impact psychological experiences. This is crucial in areas like the study of mental disorders, where understanding the biological roots can lead to more effective treatments. In contrast, the other psychological perspectives, such as Behaviorism, Cognitive Psychology, and Humanistic Psychology, focus on different aspects of human experience, such as learned behaviors, mental processes, and personal growth, but do not primarily underscore the biological basis of behavior.
