Evidence suggests that newly formed skills are preferentially consolidated by the brain during offline task-free periods. Additionally, VPL can lead to changes in brain areas associated with higher cognitive functions. Thus, training may result in changes in whole-brain networks during the offline consolidation period. To test this inference, electroencephalography (EEG) microstates were used to explore the dynamic characteristics of the whole-brain network during consolidation periods after training. Forty-five healthy young adults were randomly divided into three groups for training with moderate, easy and difficult intensity. The participants were trained on a coherent motion discrimination task, and the coherence threshold and resting EEG were measured before and after training. The results showed that visual performance improved only in the moderate training group and not in the easy or difficult training groups. Microstate analyses revealed significant decreases in the duration and occurrence rate of microstate C (often associated with the default mode network) during offline consolidation following moderate training. Moreover, the duration of microstate D (often associated with the dorsal attention network) significantly increased. However, moderate training did not change the duration or occurrence rate of microstate B (often associated with the visual network).

Previous studies demonstrated that tasks that recruit cognitive control attenuate the emotional interference effect, enhancing emotion regulation. The current study focused on the effects of oxytocin-a hormone known to influence socioemotional processing and motivation-on the interaction between emotion and cognitive control. In a double-blind placebo-controlled design, 124 male students (mean age 25.18 ± 3) were administered intranasal oxytocin or a placebo and completed self-report questionnaires, an emotional flanker task, and an emotional rating task. Consistent with our hypotheses, we found that oxytocin significantly reduced the effect of cognitive control on emotion. However, counter to our prediction, it did not affect emotional experience or perception. These findings suggest that oxytocin plays a role in shaping the association between emotion and cognitive control, specifically affecting the ability of cognitive control to regulate emotional responses, but not impacting emotional processing itself. The effect of oxytocin is attributed to its role in increasing approach motivation while reducing avoidance motivation-mechanisms supported by frontal-limbic interactions. Furthermore, it has been suggested that approach behavior is achieved by reducing inhibition. Therefore, the results may suggest changes in connectivity between frontal and emotional areas following oxytocin inhalation, leading to impaired regulation by cognitive control. These findings not only enhance our understanding of oxytocin's role in emotional processing and regulation but also highlight the importance of comprehensively examining these mechanisms due to their significant implications for both healthy populations and various psychopathologies.</p>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":" ","pages":"109004"},"PeriodicalIF":2.7,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143484636","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}

On one hand, we hope it will serve as a simple primer in the use of linear mixed modelling (LMM) for inferential statistical analysis of multimodal data. We describe how LMM can be easily adopted for the identification of trial-wise relationships between disparate measures and provide a brief cookbook for assessing the suitability of LMM in your analyses. On the other hand, this paper is an empirical report, probing how trial-wise variance in the N2pc, and specifically its sub-component the N<sub>T</sub>, can be predicted by manual reaction time (RT) and stimuli parameters. Extant work has identified a link between N2pc and RT that has been interpreted as evidence of a direct and causative relationship. However, results have left open the less-interesting possibility that the measures covary as a function of motivation or arousal. Using LMM, we demonstrate that the relationship only emerges when the N<sub>T</sub> is elicited by targets, not distractors, suggesting a discrete and functional relationship. In other analyses, we find that the target-elicited N<sub>T</sub> is sensitive to variance in distractor identity even when the distractor cannot itself elicit consistently lateralized brain activity. The N<sub>T</sub> thus appears closely linked to attentional target processing, supporting the propagation of target-related information to response preparation and execution. At the same time, we find that this component is sensitive to distractor interference, which leaves open the possibility that N<sub>T</sub> reflects brain activity responsible for the suppression of irrelevant distractor information.</div></div>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":"195 ","pages":"Article 108987"},"PeriodicalIF":2.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143043434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, empirical research has typically focused on associations between self-report scales and objective physiology during rest or bodily perturbations, without manipulating or measuring descending. Therefore, we developed the novel Adjustment to Interoceptive Discrepancy (AID) paradigm, that builds and then violates interoceptive beliefs to measure expectations and adjustment of expectations over subsequent trials following an unexpected stimulus. We validated this paradigm in the nociceptive domain in a total of 57 university-aged participants. The AID paradigm successfully induced interoceptive discrepancy (<em>i.e.,</em> a difference between expectation and perception ratings) that was resolved as participants adjusted expectations appropriately across subsequent trials. This adjustment was more rapid for stimuli that were perceived as more <em>versus</em> less intense than expected. Notably, there were individual differences in the pattern of this adjustment, revealing different strategies in how individuals adjust to unexpected interoceptive sensations, although these were unrelated to interoceptive sensibility scores. Overall, the AID paradigm provides a useful method to assess interoception across expected <em>versus</em> unexpected stimuli, to probe interindividual differences of interoceptive predictions, and ultimately to enable research on the bidirectional processing of internal stimuli in mental health.</div></div>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":"195 ","pages":"Article 109001"},"PeriodicalIF":2.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143207218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most of these studies do not examine emotions other than fear, leaving open the question of whether meanness-related alterations in fear face processing might generalize to other facial expressions, nor the role of the other constructs of the triarchic model of psychopathy (i.e., boldness and disinhibition). The current study aimed to address these issues by measuring N170 amplitudes in a mixed-gender sample of 119 undergraduates while they passively viewed a broader range of emotional facial expressions (Anger, Fear, Happiness, and Neutral) alongside control (Scrambled) pictures. The specificity of this association to trait meanness compared to the other triarchic constructs was also assessed. Our results demonstrated meanness-related reductions in N170 amplitudes across all types of facial expressions, not just to fearful faces, even after controlling for the overlap with the other triarchic constructs.

This study aimed to fill this gap by examining whether the lengths of time interval before a recalling probe influenced goal-directed and stimulus-driven internal attention. We manipulated the cue probe interval (CPI) before the probe in a working memory change detection task with a retrospective cue. In addition to behavioral performance, we also traced two electrophysiological signals of the event-related potential (ERP) components of N450 and P300 to represent goal-directed and stimulus-driven internal attention respectively. The results suggested that CPI modulated goal-directed attention with more pronounced N450 amplitudes when CPI was 2000 ms than those when CPI was 500 ms during the informative condition. Meanwhile, more pronounced P300 amplitudes were observed when CPI was 500 ms than those when CPI was 2000 ms for both the matching and nonmatching conditions. Such results lead to the conclusion that internal attention was goal-directed when CPI was as long as 2000 ms, whereas stimulus-driven when CPI is as short as 500 ms.

In Experiment 1 (web-based), younger and older participants read positive and negative target words in positive and negative contexts and rated the valence of the target words. Negative contexts biased the ratings more than positive ones, reflecting a negativity bias during offline valence evaluation in both age groups. In Experiment 2 (EEG), another group of participants read positive and negative target words in positive and negative contexts first, and then the same target words again, and made valence judgment on the target words. OAs showed a larger P2 (180–300 ms) difference before and after contexts for positive target words than younger adults (YAs). This suggests OAs’ early attention to positive features of words in contexts. YAs showed a larger late positive complex (LPC) difference for target words before and after negative contexts than before and after positive contexts, while older adults showed comparable LPC effects across all the conditions.
