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 ]
The reward system (the mesocorticolimbic circuit) is a group of neural structures responsible for incentive salience (i.e., "wanting"; desire or craving for a reward and motivation), associative learning (primarily positive reinforcement and classical conditioning), and positively-valenced emotions, particularly ones involving pleasure as a core component (e.g., joy, euphoria and ecstasy).
Specifically, Gray's theory concentrated on understanding how reward or punishment related to anxiety and impulsivity measures. His research and further studies have found that reward and punishment are under the control of separate systems and as a result people can have different sensitivities to such rewarding or punishing stimuli.

The biology-based personality theories (discussed below) are based on correlating personality traits with behavioral systems related to motivation, reward, and punishment. On a broad level, this involves the autonomic nervous system, fear-processing circuits in the amygdala , the reward pathway from the ventral tegmental area (VTA) to the ...
Intrinsic motivation comes from internal factors like enjoyment and curiosity; it contrasts with extrinsic motivation, which is driven by external factors like obtaining rewards and avoiding punishment. For conscious motivation, the individual is aware of the motive driving the behavior, which is not the case for unconscious motivation.
Managers who believe employees operate in this manner are more likely to use rewards or punishments as motivation. [6] Due to these assumptions, Theory X concludes the typical workforce operates more efficiently under a hands-on approach to management. Theory X managers believe all actions should be traceable to the individual responsible.
Content theory of human motivation includes both Abraham Maslow's hierarchy of needs and Herzberg's two-factor theory. Maslow's theory is one of the most widely discussed theories of motivation. Abraham Maslow believed that man is inherently good and argued that individuals possess a constantly growing inner drive that has great potential.
Extrinsic motivation, on the other hand, is a motivation that is provided externally such as external awards or punishments. Research has shown that incentives which reward task engagement lowers intrinsic motivation as it is much like controlling behavior.
