DOI: 10.1001/jamapsychiatry.2016.3084
Abstract: Importance Disrupted reward processing, mainly driven by striatal dysfunction, is a key characteristic of addictive behaviors. However, functional magnetic resonance imaging (fMRI) studies have reported conflicting results, with both hypoactivations and hyperactivations during anticipation and… read more here.

Reward anticipation in individuals with subclinical psychotic experiences: A functional MRI approach
Sign Up to like & getrecommendations! Published in 2019 at "European Neuropsychopharmacology"
DOI: 10.1016/j.euroneuro.2019.10.002
Abstract: Previous research in patients with psychotic disorder has shown widespread abnormalities in brain activation during reward anticipation. Research at the level of subclinical psychotic experiences in individuals unexposed to antipsychotic medication is limited with inconclusive… read more here.

DOI: 10.1017/s0033291722002707
Abstract: Abstract Aberrations in how people form expectations about rewards and how they respond to receiving rewards are thought to underlie major depressive disorder (MDD). However, the underlying mechanism linking the appetitive reward system, specifically anticipation… read more here.

DOI: 10.1017/s0033291722003592
Abstract: BACKGROUND Motivational impairment associated with deficits in processing the anticipation of future reward is hypothesized to be a cardinal feature of schizophrenia spectrum disorders (SZ). Evidence from short-term follow-up (6-week post-treatment) studies suggests that these… read more here.

DOI: 10.1093/cercor/bhac359
Abstract: Events that elicit emotional arousal or are associated with reward are more likely remembered. Emotional arousal activates the amygdala and the central noradrenergic system, whereas reward anticipation results in an activity in the mesocorticolimbic dopaminergic… read more here.

S141. REWARD PROCESSING IN CHILDREN WITH PSYCHOTIC-LIKE EXPERIENCES
Sign Up to like & getrecommendations! Published in 2020 at "Schizophrenia Bulletin"
DOI: 10.1093/schbul/sbaa031.207
Abstract: Abstract Background Individuals with psychosis display an attenuated response to reward. However, it has not yet been established whether individuals with psychotic-like experiences (PLEs) also exhibit alterations in reward anticipation. Methods The present study examined… read more here.

At‐risk alcohol users have disrupted valence discrimination during reward anticipation
Sign Up to like & getrecommendations! Published in 2022 at "Addiction Biology"
DOI: 10.1111/adb.13174
Abstract: Alcohol use disorder is characterised by disrupted reward learning, underpinned by dysfunctional cortico‐striatal reward pathways, although relatively little is known about the biology of reward processing in populations who engage in risky alcohol use. Cues… read more here.

Regulatory Effects of Reward Anticipation and Target on Attention Processing of Emotional Stimulation
Sign Up to like & getrecommendations! Published in 2020 at "Frontiers in Psychology"
DOI: 10.3389/fpsyg.2020.01170
Abstract: Studies suggest that reward and emotion are interdependent. However, there are discrepancies regarding the interaction between these variables. Some researchers speculate that the inconsistent findings may be due to different targets being used. Although reward… read more here.
