What Is The Role Of Physiological Psychology In Living Organisms?

Physiological psychology:
It examines the physiology of behavior. It looks for casual events in an organism's physiology especially in the nervous system and its interaction with glands that secrete hormone. Physiological psychologists study almost all behavioral phenomena that can be observed in non-human animals, including learning memory, sensory processes, emotional behavior, motivation, sexual behavior and sleep. Physiological psychologist usual studies animals because most physiological experiments cannot ethically be performed using humans.

Psychologists have much to tell us about drug abuse. Most importantly, they have discovered that all drugs having the potential for addiction act on a particular system in the brain i.e., involved in our reactions to pleasurable events such as encountering food , warmth, an sexual contact. Some drugs artificially activate this system, providing effects on behavior similar to those that pleasurable events naturally produce.

Psychophysiology is the measurements of people's physiological reactions such as heart rate, blood pressure, electrical resistance of the skin, muscle tension and electrical activity of the brain. These measurements provide an indication of a person degree of relaxation. Most psycho physiologists investigate phenomena such as stress and emotions.
