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).
If the systems are assumed to be functionally related, the effect of a given stimulus is dependent upon the strength of that stimulus, reactivity in the activated system, and strength of the competing system. [3] Thus, for a reward, the behavior output from BAS is dependent on the strength of the reward, activation of the BAS, and inhibition ...
The neuronal axons of the mesolimbic dopamine system, a key component of the reward circuitry, generally have high thresholds for stimulation. However, these thresholds can be increased or decreased by drug administration, influencing sensitivity to intracranial stimulation and ICSS behavior.
An addictive drug is defined as a substance that affects the mesolimbic system directly or indirectly by increasing extracellular levels of dopamine. [ 24 ] Common addictive substances such as cocaine , alcohol , and nicotine have been shown to increase extracellular levels of dopamine within the mesolimbic pathway, preferentially within the ...
Typically, parents learn to reward appropriate behavior through social rewards (such as praise, smiles, and hugs) as well as concrete rewards (such as stickers or points towards a larger reward as part of an incentive system created collaboratively with the child). [35]
Reward dependence drives behavior maintenance systems, and in addictive behaviors, maintenance of behaviors occurs despite adverse consequences. The brain on substance dependence. According to researchers the reward circuit is continuously involved in initiating behaviors that are essential for the sustenance of the individual (such as eating ...

The effectiveness of an organization's performance and reward management system can have a significant impact on employee motivation, morale, and ultimately, their productivity. According to a 2008 study, a poorly designed or implemented reward system can lead to counterproductive behaviour and ultimately undermine the goals of the organisation.
