Neural processing of reward and loss in girls at risk for major depression.
CONTEXT Deficits in reward processing and their neural correlates have been associated with major depression. However, it is unclear if these deficits precede the onset of depression or are a consequence of this disorder. OBJECTIVE To determine whether anomalous neural processing of reward characterizes children at familial risk for depression in the absence of a personal history of diagnosab...
متن کاملIndividual differences and the neural representations of reward expectation and reward prediction error.
Reward expectation and reward prediction errors are thought to be critical for dynamic adjustments in decision-making and reward-seeking behavior, but little is known about their representation in the brain during uncertainty and risk-taking. Furthermore, little is known about what role individual differences might play in such reinforcement processes. In this study, it is shown behavioral and ...
متن کاملReward and punishment processing in depression.
Depression is a complex and heterogeneous disorder whose cause is poorly understood. Theories on the mechanisms of the disease have often focused on either its neurobiology or its cognitive and behavioral manifestations. Recently, studies exploring how depressed patients process reward and punishment have linked these two facets together. It has been suggested that individuals with a dysfunctio...
متن کاملDysfunctional Reward Processing in Depression.
Anhedonia - diminished pleasure and/or decreased reactivity to pleasurable stimuli - is a core feature of depression that frequently persists after treatment. As a result, extensive effort has been directed towards characterizing the psychological and biological processes that mediate dysfunctional reward processing in depression. Reward processing can be parsed into sub-components that include...
متن کاملDopamine, Reward Prediction Error, and Economics∗
The neurotransmitter dopamine has been found to play a crucial role in choice, learning and belief formation. The best developed current theory of dopaminergic function is the “reward prediction error” hypothesis that dopamine encodes the difference between the experienced and predicted “reward” of an event. We provide axiomatic foundations for this hypothesis to help bridge the current concept...
