Reinforcement sensitivity theory (RST) proposes three brain-behavioral systems that underlie individual differences in sensitivity to reward, punishment, and motivation. While not originally defined as a theory of personality , the RST has been used to study and predict anxiety , impulsivity , and extraversion . [ 1 ]
Gray's reinforcement sensitivity theory (RST) is based on the idea that there are three brain systems that all differently respond to rewarding and punishing stimuli. [3] Fight-flight-freeze system (FFFS) – mediates the emotion of fear (not anxiety) and active avoidance of dangerous situations. The personality traits associated with this ...
The biopsychological theory of personality is similar to another one of Gray's theories, reinforcement sensitivity theory. The original version of Gray’s reinforcement sensitivity theory of personality was developed in 1976 and Gray revised it independently in 1982. Then in 2000 further and more thorough revisions were made alongside McNaughton.
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 ...
[83] [94] This model is based on the reinforcement sensitivity theory by Jeffrey Alan Gray, which states that people with stronger behavioral activation system are high in reward responsiveness and are predisposed to the personality trait of extraversion, while people with a stronger behavioral inhibition system are lower in reward ...

The standard definition of behavioral reinforcement has been criticized as circular, since it appears to argue that response strength is increased by reinforcement, and defines reinforcement as something that increases response strength (i.e., response strength is increased by things that increase response strength).
In the functionalist theory, for every discriminated difference in function, there is a difference in qualia. In discussing this question further, Gray looked at synaesthesia , where he described modalities as becoming mixed, for example when sounds are experienced with colour.
