[25] Gray’s Theory differed from Eysenck's as Eysenck ...
Gray's reinforcement sensitivity theory (RST) consists of two motivational systems: the behaviour inhibition system (BIS) and the behaviour activation system (BAS). [32] [33] The BIS is responsible for organizing behaviour in response to adverse stimuli. In other words, stimuli associated with punishment or the omission/termination of reward ...
Eysenck has written and co-written many publications, including several textbooks. In the late 1990s, he developed the theory of the "hedonic treadmill", [2] stating that humans are predisposed by genetics to plateau at a certain level of happiness, and that the occurrence of novel happy events merely elevates this level temporarily.
