Physiological psychology is a field of study that investigates the biological and physiological basis of behavior in humans and animals. The discipline encompasses a range of sub-fields, including behavioral neuroscience, biopsychology, and psychophysiology. Synonyms for physiological psychology include biological psychology, neurobiology, neuropsychology, behavioral genetics, and cognitive neuroscience. These terms all relate to the scientific study of the connection between the brain and behavior and the role that genetics and environmental factors play in shaping cognitive and behavioral processes. By exploring the different components that contribute to the complex interplay between brain function and behavior, these fields aim to enhance our understanding of human psychology and inform the development of effective interventions for mental health and neurological disorders.
