Physiological Psychology and Neuroscience

Groups the branches that explain behavior and mental life through the body's physical machinery: Biological Psychology studies the nervous system's role in behavior generally, Neuropsychology studies how brain structure and damage relate to cognition and behavior, Psychophysiology measures the physiological responses, such as heart rate and skin conductance, that accompany mental states, Psychopharmacology studies how drugs affect the brain, mood and behavior, and Behavioral Genetics studies how genes and environment jointly shape behavioral traits. A branch whose central variable is social, cultural or purely mental rather than bodily belongs elsewhere.
