Frontiers in Systems Neuroscience, 2022 Neuroimaging techniques have advanced our knowledge about neurobiological mechanisms of reward and emotion processing. It remains unclear whether reward and emotion-related processing share the same neural connection topology and how intrinsic brain ...

Encoding tasks moderated the reward effect on brain activity during memory retrieval
Scientific Reports, 2022 Previous studies have explored the effects of retrieval reward and depth of processing in encoding on recognition, but it remains unclear whether and how reward and depth of processing during encoding influence recognition. We investigated the effect and

Dysfunctional reward processing in depression [PDF]
Current Opinion in Psychology, 2015 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

Task-level value affects trial-level reward processing
NeuroImage, 2022 Despite disagreement about how anterior cingulate cortex (ACC) supports decision making, a recent hypothesis suggests that activity in this region is best understood in the context of a task or series of tasks.

A Combined Effect of Self and Reward: Relationship of Self- and Reward-Bias on Associative Learning
Frontiers in Psychology, 2021 Previous studies have demonstrated that individuals process information related to themselves or a high reward quickly and have referred to this as self-bias or reward-bias.

Markov Rewards Processes with Impulse Rewards and Absorbing States
CoRR, 2021 We study the expected accumulated reward for a discrete-time Markov reward model with absorbing states. The rewards are impulse rewards, where a reward $ρ_{ij}$ is accumulated when transitioning from state $i$ to state $j$. We derive an explicit, single-letter expression for the expected accumulated reward as a function of the number of time steps $n ...

Individual differences in reward-prediction-error: extraversion and feedback-related negativity [PDF]
, 2010 Medial frontal scalp-recorded negativity occurring ∼200–300 ms post-stimulus [known as feedback-related negativity (FRN)] is attenuated following unpredicted reward and potentiated following unpredicted non-reward.

Dopamine restores reward prediction errors in old age [PDF]
, 2013 Senescence affects the ability to utilize information about the likelihood of rewards for optimal decision-making. Using functional magnetic resonance imaging in humans, we found that healthy older adults had an abnormal signature of expected value ...

Altered Reward Processing System in Internet Gaming Disorder
Frontiers in Psychiatry, 2020 Converging evidence indicates that addiction involves impairment in reward processing systems. However, the patterns of dysfunction in different stages of reward processing in internet gaming addiction remain unclear.
