While both low-trait mindfulness and blunted neural processing to emotional stimuli (indexed by the late positive potential; LPP) have been separately associated with depression, previous work has highlighted an inverse relationship between trait mindfulness and neural emotional processing. Thus, it remains unclear how facets of trait mindfulness and neural emotional processing interact as risk factors for PPD. During the second trimester, pregnant women (n = 117) completed the Five Facet Mindfulness Questionnaire, the Inventory of Depression and Anxiety Symptoms (IDAS), and an infant face matching task while continuous electroencephalography was recorded. At 9 weeks postpartum, participants' PPD symptoms were reassessed with the IDAS. A series of hierarchical linear regression models revealed that acting with awareness, a trait mindfulness facet, and LPP to happy infant faces interacted to predict PPD symptoms (β = .217, p = .014, 95% CI [.045, .390]) after adjusting for depression levels in mid-pregnancy, such that low acting with awareness was associated with greater PPD symptoms when LPP to happy infant faces was 1 standard deviation below (β = -.548, SE = .150 , p < .001) and at the mean (β = -.309, SE = .106, p = .004).

This study applied a sequential effort-based decision-making task during functional magnetic resonance imaging to quantify motivation and test for potential neurofunctional differences during prospective effort/reward encoding (Cue1), integration of effort and reward cues (Cue2), and choice behaviour in individuals with CUD (n = 21) and healthy controls (HCs) (n = 20). Behavioural in-scanner results demonstrated that participants in both groups made significantly fewer high-effort choices as effort levels increased on the task, yet they selected significantly more high-reward choices as reward magnitude increased. At the neural level, the CUD group showed decreased ventromedial prefrontal cortex activity, as well as reduced activity in the culmen, posterior cingulate, and superior temporal gyrus during the encoding of prospective effort and reward cues (Cue1) respectively, compared with controls. Conversely, the CUD group showed increased parietal lobule, superior temporal gyrus, fusiform gyrus, middle occipital gyrus, cingulate gyrus, and claustrum activity during the integration phase of the task (Cue2) relative to controls. Exploratory correlations revealed that bilateral ventral striatum activity during prospective effort cues was associated with the proportion of accepted high-effort and high-reward trials, predominantly driven by the CUD group. Altogether, these findings indicate fronto-striatal but also posterior cortical processing alterations during prospective signaling and during effort-reward information integration.

A frontocentral ERP associated with reward feedback, the reward positivity (RewP), has been linked to reflect information about reward value and motivational states. It is, however, unclear if changes in the RewP are influenced by changes in reward value as a function of motivational state. To examine this, hungry participants (n = 31) completed two rounds of a modified Doors Task incorporating Pavlovian conditioning during EEG recordings and obtained feedback associated with sweet and savory food reinforcers equally matched in pleasantness and desirability. Participants underwent reinforcer devaluation, a paradigm designed to isolate inference-based behavior based on decreasing reward value, in between rounds by eating one of the foods to satiety. Prior to devaluation, participants were hungry and rated both food reinforcers equally pleasant. After devaluation, participants were sated and rated the devalued food, but not the non-devalued food, significantly less pleasant, suggesting a sensory-specific change in reward value. Logistic regression of win-stay/lose-switch behavior during the Doors Task shows participants made sensory-specific adjustments in food preferences during postdevaluation. Nonparametric permutation tests based on the tmax statistic performed revealed no significant differences in RewP amplitudes, suggesting the RewP is insensitive to reinforcer devaluation. This could not be explained by differences in perceived pleasantness or desirability. These findings suggest that affective and motivational factors such as tracking inferences based on decreases in reward value did not modulate the RewP.</p>","PeriodicalId":50672,"journal":{"name":"Cognitive Affective & Behavioral Neuroscience","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144227475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Downstream effects are also hypothesized for episodic memory with impairments particularly for positive information due to dopamine dysregulation from anhedonia affecting memory formation processes. To examine the association of memory impairments in individuals with mild-to-severe anhedonia and depressive symptoms, 108 young adults completed a working memory task where they had to remember an abstract shape while presented with two consecutive positive, neutral, or negative images. This task was followed by a surprise episodic memory recognition test for the images the next day. The Drift Diffusion Model index drift rate was used to examine whether anhedonia severity predicted evidence accumulation rates during working and episodic memory retrieval. Contrary to expectations, based on multivariate models, anhedonia severity did not predict evidence accumulation rate for any specific valence in either task.
