Answer:
Behavioral scientists that investigate and explain how factors such as genetics, neurobiology, and hormonal responses can influence psychopathology are using a <u>biological</u> perspective.
Explanation:
The biological perspective focuses on the effects of the body on behavior, feelings and thoughts. The study of the biological bases of behavior is a link between two disciplines: psychology and biology. In this sense, the biological perspective implies the study of the behavior and mental processes of the individuals attending to their biological components. The biological perspective, also called neurophysiological, assumes that the mental disorder is a disease, just like any other physical illness and that psychopathological alterations are caused by biological abnormalities, such alterations can be the result of genetic factors, metabolic or hormonal disorders, physical trauma among others. The alteration of the brain is the primary cause of the abnormal behavior.
