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). This study revealed the activity of whole-brain networks in the consolidation period after VPL.</div></div>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":"196 ","pages":"Article 109008"},"PeriodicalIF":2.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143544593","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}

This study aims to address this by exploring whether resting state electroencephalography (EEG) power, among traditional frequency bands (delta, theta, alpha, beta), predicts cyberbullying experiences over time. Participants (<em>N</em> = 167 with <em>n</em> = 904 datapoints; aged 12.0–17.9 years) completed EEG and other assessments at 4 monthly-intervals for five years. Results revealed several associations between EEG power across brain regions and various cyberbullying roles. Key findings include a decrease in EEG power across all frequency bands over time across the entire sample, aligning with typical developmental patterns. However, in early adolescence, cyberbully-victims exhibited lower delta power compared to other groups, which may suggest heightened emotional reactivity. Conversely, later in adolescence there were decreases in delta power among cyberbullies, potentially reflecting an adaptive stress response. Longitudinally, cyberbully-victims retained more alpha power over time (i.e., into later adolescence) in frontal and central regions, suggesting greater cognitive effort in processing emotional experiences. Additionally, cyberbullies showed a relatively steeper decline in alpha power (into later adolescence) in frontal regions, possibly linked to impulsivity and higher levels of general aggression. Longitudinal analyses highlight the importance of early interventions to target cognitive and emotional processes that may be implicated in cyberbullying in order to reduce the impact of cyberbullying and protect the mental health of adolescents. Future research should involve larger, more diverse samples to improve our knowledge of complex relationships in this research area.</div></div>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":"196 ","pages":"Article 109019"},"PeriodicalIF":2.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143755699","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}

We manipulated contextual valence as a gain versus a loss context. In the gain context, decisions resulted in either gains or nongains, while in the loss context, decisions led to losses or nonlosses. We recorded EEG from 40 participants while they completed a wheel-of-fortune task under conditions of risk and ambiguity in both contexts. We observed a stronger valence effect on the P3a in the loss context under risk, but a stronger valence effect on the P3b in the gain context under ambiguity. Further comparisons revealed that feedback evaluation was primarily driven by a smaller P3a in response to losses under risk, but by a larger P3a and P3b in response to gains under ambiguity. Parametric analyses found that both the reward positivity and P3a for gains and nongains were modulated by winning probability under risk, while the P3a for gains was influenced by ambiguity level under ambiguity.

The assessed molecular indices were serum levels of osteocalcin (OC), uncarboxylated OC (ucOC), carboxylated OC (cOC), brain-derived neurotrophic factor (BDNF), and irisin, and the assessed neurocognitive indices were the accuracy rate (AR), reaction time (RT), and electroencephalography event-related potentials (ERPs) of P2 and P3 components in a visuospatial working memory task. Data on these indices before versus after an acute bout of HIIAE or HIIAE+WBV or after a resting session were compared. An HIIAE or HIIAE+WBV intervention yielded no significant change in ERP P2 latency/amplitude and P3 latency but yielded significantly higher ARs, shorter RTs, larger ERP P3 amplitudes, and higher OC, cOC, BDNF, and irisin levels in the postmenopausal women.

To better understand the nature of aggressive people's reappraisal difficulties, we developed an event-related brain potential (ERP) protocol inspired by Zaki's (2013) cue integration model. The objective of this study was to track the neural activity associated with the violation of expectations about hostile vs. nonhostile intentions in aggressive and nonaggressive individuals when facing conflicting contextual and behavioral cues in a given social situation. We hypothesized that aggressive individuals do not integrate nonhostile contextual information and, therefore, overestimate the behavioral hostile cues. Our sample consisted of women from the community (n = 23) and a prison (n = 20). Taken together, the results suggest that aggressive individuals demonstrate an impulsivity in their decision-making about other people’s intentions. This would be the case, not because they fail to seek out mitigating information, but rather because they fail to complete the inferential processes about the hostile and nonhostile information before making a judgement about the other’s intent. In contrast with aggressive individuals, non-aggressive people would be able to make a decision when facing conflicting information about the other’s mental state by privileging contextual cues in order to attenuate their attribution of hostile intention based on the behavior of others.</div></div>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":"196 ","pages":"Article 109017"},"PeriodicalIF":2.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143724664","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}

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.</div></div>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":"196 ","pages":"Article 109004"},"PeriodicalIF":2.7,"publicationDate":"2025-03-01","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}

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_T, 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_T is elicited by targets, not distractors, suggesting a discrete and functional relationship. In other analyses, we find that the target-elicited N_T is sensitive to variance in distractor identity even when the distractor cannot itself elicit consistently lateralized brain activity. The N_T 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_T 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}
