Gray’s Reinforcements Sensitivity Theory

The theory proposed in the late 1970s and early 1980s by Jeffrey Gray postulates that people differ in how sensitive they are to rewards and punishments. It is one of the major theories of personality proposing that three systems called behavioral activation system, behavioral inhibition system, and the fight-flight-or-freeze systems determine a wide range of human behavior.
