Summary: Up to 50% of new mothers experience baby blues (BB) within a week of delivery, with affective disturbances being the central symptoms. This study investigates whether incentive processing during the experience of BB can be altered through the monetary incentive delay (MID) task. The results demonstrate that the BB-related time window overlaps with alterations in the brain networks associated with incentive processing.

Summary: Deficits in neural processing of reward are found in both bipolar disorder (BD) and schizophrenia (SZ), but the underlying mechanisms are unclear. This study shows that adaptive coding is impaired in both BD and SZ patients, but the affected brain regions differ. BD patients show more preserved adaptive coding compared to SZ patients in certain brain regions.

Summary: The research shows that people use stereotypes and prior knowledge to predict others' responses in interpersonal communication. The study found that when perceivers observe information consistent with their social expectations, brain regions associated with reward processing are activated, and perceivers are willing to forgo money to achieve their expectations.

Summary: This study evaluated the similarities and differences between contrasts in the Monetary Incentive Delay task and found more similarities than differences between win and loss cues during the anticipation contrast. There were some dissimilarities between win anticipation contrasts and an apparent deactivation effect in the outcome phase, likely stemming from the blood oxygen level-dependent undershoot.

Summary: Reward and punishment play a crucial role in motivating decision-making and behavior changes. Through a meta-analysis of studies on the monetary incentive delay task (MIDT), this research identifies the shared and distinct neural responses during win and loss anticipation and outcome. Understanding these neural processes can contribute to empirical research on motivated behaviors and psychopathology.

Summary: Research shows cognitive and neurobiological overlap between sign-tracking and maladaptive behavior. The study investigates the neural correlates of sign-tracking by using an additional singleton task and fMRI. The results suggest that sign-tracking is associated with activation of the 'attention and salience network' in response to reward cues but not reward feedback, demonstrating a distinction between the two in the brain.

Summary: As public access to longitudinal developmental datasets like the Adolescent Brain Cognitive Development Study increases, it is important to have resources to differentiate time-dependent effects. In this study, an accelerated adult equivalent of the ABCD Study dataset was created to quantify developmental changes. The results showed that task-based brain activation was more similar within individuals across repeated scan sessions than between individuals, indicating differences in data reliability.

Summary: The study found a neurobiological foundation for the protective aspect of hyperthymic temperament against depression in the reward system, suggesting that hyperthymic temperament may modulate attentional or motor responses or optimal selection of behavior based on reward, rather than value representation.

Summary: Obesity is associated with alterations in brain structure and function, particularly in areas related to reward processing. Functional neuroimaging studies with modest sample sizes have shown that higher body weight is associated with hyperresponsiveness of the reward circuit. However, a large-sample study was conducted to replicate this finding and investigate reward processing in individuals with higher body weight but below the clinical obesity threshold. The results show that higher BMI is associated with increased reward response in the insula, and this association is no longer significant when individuals with obesity are excluded from the analysis. The study also found higher activation in obese individuals compared to lean individuals, but no difference between lean and overweight participants.

Summary: The study found that the level of attachment dogs feel towards their owners affects their neural activity response to their owner's voice and praise, showing similarities to infant-mother attachment.

Summary: There is a reciprocal relationship between chronic pain and reward processing. This study found that males with chronic pain exhibited reduced anticipatory responses to reward in the striatum compared to control males, while no significant sex differences were observed among female patients. These findings highlight the importance of considering sex as a factor of interest in future studies on reward processing in the context of chronic pain.

Summary: Individuals with Internet Gaming Disorder (IGD) show a preference for risky behavior in pursuit of high rewards compared to healthy controls (HC), and exhibit exaggerated brain activity in the striatum during reward anticipation and outcome monitoring. These findings suggest that oversensitivity of the reward system to potential and positive rewards drives individuals with IGD to approach risky options more frequently.

Summary: The study found that greater putamen activity and less amygdala activity in response to angry faces were related to greater social anxiety severity in individuals with Social Anxiety Disorder. However, there was no relationship between brain activity in response to fearful faces and social anxiety severity. Clinical features revealed that levels of anhedonia and general anxiety symptoms may contribute to social anxiety severity.

Summary: This study compared the activation of the striatum during reward anticipation between patients with alcohol use disorder (AUD) and gambling disorder (GD) using functional MRI. The results showed hypoactivation of the reward system in AUD patients compared to healthy controls. However, the study did not support the hypothesis that addiction-related cues explain striatal dysfunction.

Summary: The hormone ghrelin influences food search and consumption, as well as the value of non-food rewards. This study investigated the relationship between nutritional state, ghrelin concentrations, and subjective/neural responses to social and non-social rewards. The results showed that ghrelin did not affect the response to social rewards, but reduced activation in the prefrontal cortex for non-social rewards when ghrelin was suppressed after a meal.

Summary: A socially consequential test was conducted to determine whether sharing a group membership with another person impacts the encoding of their face. The researchers conducted two large-scale, preregistered ERP studies to investigate the influence of methodological decisions on the top-down effects of group membership on face perception. The results showed that mere group membership did not significantly affect the N170 response, but the background color used to indicate group membership modulated the N170. The study also found that stimulus race/ethnicity had an effect on face perception.

Summary: Pietraszewski's claim that social psychological research on groups is theoretically useless due to its vagueness, tautology, and dependence on intuitions is opposed by the authors. They argue that while Pietraszewski's contribution is thought-provoking, it is also incomplete and guilty of the faults he attributes to others. The authors advocate for the integration of new and old ideas instead of completely overturning existing knowledge.

Summary: The study shows that category labels can significantly influence responses in intergroup contexts, affecting how participants perceive ingroup and outgroup members as well as how they allocate resources. In minimal group paradigms, seemingly arbitrary category labels can imply characteristics about groups that may alter responses, even more so than intergroup effects.
