Reward deprivation, reward deficit or reward deficiency is a brain state in which a significant source of reward is missing. Reward deprivation results in behaviors in which the brain will seek new sources of compensatory reward. For example, a child subjected to maternal separation may show improved learning for the sake of pleasing its guardians in a quest to obtain rewards such as praise or warmth. A child subjected to limited freedoms in compulsory schooling may be more prone to addictions, e.g. videogame addictions or drug addictions. Similarly, an adult who operates in conditions of stress or learned helplessness is more likely to compensate reward deficit with food rewards, which may lead to obesity.

Reward deficiency might be associated with a reduced number of dopamine D2 receptors in reward circuits. Such deficit may come from genetic variations (DRD2 gene) or dopamine receptor downregulation (e.g. as a result of substance abuse).
