The biological perspective is a way of looking at psychological topics by studying the physical basis for animal and human behavior. It is one of the major perspectives in psychology, and involves such things as studying the immune system, nervous system and genetics.
This field of psychology is often referred to as biopsychology or physiological psychology.
The study of physiology and biological process has played a major role in psychology since its earliest beginnings. This perspective has grown considerably in recent years as the technology used to study the brain and nervous system has grown increasingly advanced. Today, scientists use tools such as PET and MRI scans to look at how drugs, disease and brain damage impact behavior and cognitive functioning.
