Fear of positive evaluation (FPE), a core cognitive feature of social anxiety disorder (SAD), is posited to drive maladaptive responses to social feedback, yet its neurocognitive underpinnings remain poorly understood. This study employed event-related potentials (ERPs) to investigate how FPE modulates neural dynamics during social feedback processing. High- and low-FPE individuals (N = 48) completed a social evaluation perception task, where they received positive or negative feedback from different sources (i.e., human/computer). Individuals exhibited sensitivity to feedback source and valence, which was reflected in several event-related potential components associated with early attention (N1), perceptual integration (P2), reward evaluation (Reward Positivity, RewP), and elaborate processing (Late Positive Potential, LPP). Critically, high-FPE (hFPE) individuals demonstrated heightened early attentional vigilance (enhanced N1 amplitudes) to negative feedback from both human and computer sources, with N1 amplitudes positively correlating with FPES scores. Notably, human-positive feedback also elicited larger N1 amplitudes in the hFPE group, further positively linked to FPES scores. Additionally, hFPE individuals showed sustained processing with negative evaluations, evidenced by enhanced LPP amplitudes for negative feedback compared to low-FPE (lFPE) individuals. Although limited by the non-clinical sample, these findings highlight the distinct neural signatures of FPE and its role in abnormal social feedback processing, particularly suggesting the N1 component may be a potential physiological marker for identifying social anxiety patients with predominant fear of positive evaluation, thereby facilitating targeted therapeutic interventions.

积极评价恐惧（FPE）是社交焦虑障碍（SAD）的一个核心认知特征，被认为会导致对社会反馈的不适应反应，但其神经认知基础尚不清楚。本研究采用事件相关电位（ERPs）研究FPE如何调节社会反馈加工过程中的神经动力学。高fpe和低fpe个体（N=48）完成了一项社会评价感知任务，他们从不同的来源（即人/计算机）获得积极或消极的反馈。个体表现出对反馈源和效价的敏感性，这反映在与早期注意（N1）、知觉整合（P2）、奖励评价（reward Positivity, RewP）和精细加工（Late Positive potential， LPP）相关的事件相关电位成分中。重要的是，高fpe （hFPE）个体对人类和计算机源的负面反馈表现出更高的早期注意警觉性（增强的N1振幅），N1振幅与FPES分数呈正相关。值得注意的是，人类的积极反馈在hFPE组中也引起了更大的N1振幅，进一步与FPES得分呈正相关。此外，与低fpe个体相比，高fpe个体表现出持续的负面评价加工，这可以通过负面反馈的LPP振幅增强来证明。尽管受到非临床样本的限制，这些发现强调了FPE的独特神经特征及其在异常社会反馈处理中的作用，特别是表明N1成分可能是识别主要恐惧积极评价的社交焦虑患者的潜在生理标志物，从而促进有针对性的治疗干预。

Sustained attention is essential for effective cognitive performance in daily life, yet it remains challenging to monitor continuously in real time. This study examined whether pupil-based physiological markers - specifically task-evoked pupil dilation (TEPD) and baseline pupil size (BPS) - reflect fluctuations in sustained attention and alertness during a prolonged auditory continuous performance task (A-CPT). In two experiments (total N = 54), participants listened to a stream of spoken syllables and responded to a predefined target while their pupil size was continuously recorded. Intra-individual variability in reaction time served as an index of sustained attention, with higher variability reflecting poorer sustained attention. Across both experiments, a consistent positive linear relationship was found between TEPD and intra-individual varability: smaller TEPD values were associated with greater response consistency, indicating higher sustained attention. Additionally, TEPD was positively correlated with self-reported ADHD symptoms across participants, and contributed to their prediction above and beyond the behavioral task performance. This suggests that TEPD reflects inattention, hyperactivity and impulsivity symptoms across neurotypical individuals. In contrast, BPS showed a less consistent relationship with sustained attention: while it was positively associated with intra-individual varability in one experiment, this effect did not replicate in the second. These findings suggest that pupil size can serve as a continuous, implicit marker of sustained attention and a predictor of ADHD symptoms. By capturing moment-to-moment fluctuations in attentional state, pupil size offers a promising, non-invasive index of attention in real-world listening environments.

持续的注意力对于日常生活中有效的认知表现至关重要，但持续的实时监控仍然具有挑战性。本研究考察了基于瞳孔的生理标记——特别是任务诱发瞳孔扩张（TEPD）和基线瞳孔大小（BPS）——是否反映了长时间听觉连续表现任务（a - cpt）期间持续注意力和警觉性的波动。在两个实验中（总共54人），参与者听了一串口语音节，并对预先设定的目标做出反应，同时他们的瞳孔大小被连续记录下来。反应时间的个体内变异性是持续注意的一个指标，变异性越高，持续注意越差。在这两个实验中，发现TEPD与个体内部变异性之间存在一致的正线性关系：较小的TEPD值与较高的反应一致性相关，表明较高的持续注意。此外，TEPD与参与者自我报告的ADHD症状呈正相关，并有助于他们预测行为任务表现。这表明TEPD反映了神经正常个体的注意力不集中、多动和冲动症状。相比之下，BPS与持续注意力的关系不太一致：虽然在一个实验中它与个体内部变异性呈正相关，但这种效应在第二个实验中没有重复。这些发现表明，瞳孔大小可以作为持续注意力的一个连续的、隐含的标志，也是ADHD症状的一个预测指标。通过捕捉注意力状态每时每刻的波动，瞳孔大小为真实听力环境中的注意力提供了一个有希望的、非侵入性的指标。

The chronic hypoxic environment at high altitude promotes compensatory changes in the hematological system and may influence depression. However, it remains unclear how hematological compensation affects depression through brain structural mechanisms. In this study, we performed structural magnetic resonance imaging (MRI) on 129 healthy adult participants who had resided at high altitude for an extended period, and collected their routine blood test data along with depression subscale scores from the Symptom Checklist-90 (SCL-90). Cluster analysis based on red blood cell count (RBC), hemoglobin (HGB), and hematocrit (HCT) divided participants into three groups, reflecting varying levels of hematological compensation. Analysis of variance revealed significant group differences in right insula volume (F(2, 126) = 18.42, p < 0.001, partial η² = 0.24) and depression scores (F(2, 126) = 3.37, p = 0.038, partial η² = 0.05). Individuals with higher hematological compensation exhibited significantly larger right insula volumes and lower depression scores. Further mediation analysis revealed a significant indirect effect of hematological compensation on depression via right insula volume. The relative indirect effects were statistically significant (X1: Effect = −0.10, 95 % CI [−0.323, −0.007]; X2: Effect = −0.31, 95 % CI [−0.668, −0.048]). These results suggest that hematological compensation may reduce depression by increasing the volume of right insula. The findings indicate that the right insula may serve as a neural pathway linking physiological adaptation and emotional states, contributing to mental health regulation under chronic hypoxic conditions.

高海拔的慢性缺氧环境促进了血液系统的代偿性变化，并可能影响抑郁症。然而，目前尚不清楚血液代偿如何通过大脑结构机制影响抑郁症。在本研究中，我们对129名长期居住在高海拔地区的健康成人进行了结构磁共振成像（MRI），并收集了他们的常规血液检查数据以及症状检查表-90 （SCL-90）的抑郁亚量表得分。基于红细胞计数（RBC）、血红蛋白（HGB）和红细胞压积（HCT）的聚类分析将参与者分为三组，反映了不同的血液代偿水平。方差分析显示，组间右岛体积（F(2,126) = 18.42,p <； 0.001，偏η²= 0.24）和抑郁评分（F(2,126) = 3.37,p = 0.038，偏η²= 0.05）差异有统计学意义。具有较高血液学代偿的个体表现出更大的右岛体积和更低的抑郁得分。进一步的中介分析显示血液学代偿通过右岛容积对抑郁有显著的间接影响。相对间接效应具有统计学意义（X1: Effect =−0.10,95 % CI[−0.323,−0.007];X2: Effect =−0.31,95 % CI[−0.668,−0.048]）。这些结果表明，血液学代偿可能通过增加右脑岛容量来减轻抑郁。研究结果表明，右脑岛可能是连接生理适应和情绪状态的神经通路，有助于慢性缺氧条件下的心理健康调节。

Adolescents of mothers with internalizing symptoms are at higher risk of developing these symptoms than those of unaffected mothers. The error-related negativity (ERN) is a proposed neural endophenotype of anxiety and depression risk, but it is unclear whether a mother’s ERN predicts intergenerational risk. Identifying biomarkers that predict such risk could strengthen biological models of transmission and inform prevention. We used path analysis to examine the intergenerational transmission of the ERN, anxiety, and depression symptoms in 162 adolescents aged 11–14 and their mothers. Participants completed a Flanker task while we recorded their brain activity using electroencephalography (EEG) to measure the ERN, correct related negativity (CRN) and their difference (ΔERN). Greater maternal ΔERN predicted higher offspring anxiety and depression, after controlling for maternal symptoms. These findings suggest that enhanced maternal ΔERN may be one mechanism through which internalizing disorder risk is transmitted to offspring.

母亲有内化症状的青少年比母亲没有内化症状的青少年患这些症状的风险更高。错误相关负性（error-related negative， ERN）是一种被提出的焦虑和抑郁风险的神经内表型，但尚不清楚母亲的ERN是否能预测代际风险。识别预测这种风险的生物标志物可以加强传播的生物学模型，并为预防提供信息。本研究采用通径分析方法对162名11-14岁青少年及其母亲的ERN、焦虑和抑郁症状的代际传递进行了研究。参与者完成了一个Flanker任务，同时我们使用脑电图（EEG）记录了他们的大脑活动，以测量ERN，纠正相关负性（CRN）及其差异（ΔERN）。在控制了母亲的症状后，更大的母亲ΔERN预示着更高的后代焦虑和抑郁。这些发现表明，增强的母体ΔERN可能是一种机制，通过内化障碍风险传递给后代。

This study investigated the dynamics of cardiac reactivity during the performance of three cognitive tasks involving various levels of inhibition control in young and middle-aged adults. Twenty-eight young adults (18–27 years) and twenty-two middle-aged adults (55–65 years) performed variations of a flanker task involving neutral, congruent, incongruent and No-Go trials, while their cardiovascular parameters (heart rate, blood pressure, cardiac Pre-Ejection Period: PEP) were recorded. Specifically, each task was repeated twice and we examined variations of PEP and PEP reactivity as a function of time on task and task repetition. The results revealed that PEP reactivity was shown to be a transient phenomenon, decreasing both over the course of each task (only significant during the first minute) and across repeated sessions. PEP reactivity was related to cognitive load, albeit not in a linear fashion, but was not clearly related to cognitive performance. Age-related effects were demonstrated for cognitive performance as well as resting and task PEP values, but not for PEP reactivity. It is concluded that PEP reactivity showed characteristics of habituation and sensitization that are discussed in light of the theory of dual-process habituation and the model of effort and cardiovascular response.

本研究探讨了中青年在执行三种不同程度的抑制控制的认知任务时心脏反应性的动态变化。28名青壮年（18-27岁）和22名中年人（55-65岁）分别进行了中性、一致、不一致和不一致试验，同时记录了他们的心血管参数（心率、血压、心脏射血前期：PEP）。具体来说，每个任务重复两次，我们检查了PEP和PEP反应性的变化作为任务和任务重复时间的函数。结果显示，PEP反应性是一种短暂的现象，在每个任务的过程中（仅在第一分钟显著）和重复的会话中都有所下降。PEP反应性与认知负荷相关，尽管不是线性关系，但与认知表现的关系不明显。年龄对认知表现、休息和任务PEP值有影响，但对PEP反应性没有影响。结论PEP反应性具有习惯化和敏化的特点，并结合双过程习惯化理论和努力-心血管反应模型进行了探讨。

The homeostatic regulation of sleep is thought to underlie the temporal progressive decline in vigilance. However, accumulating evidence indicated that the decline in vigilance does not follow a simple linear trajectory in sleep loss. Therefore, it is necessary to investigate how vigilance degradation progressively evolves during prolonged wakefulness and to capture the temporal progression of cortical neural activities associated with this variation. Forty-five healthy young adults underwent a prolonged period of wakefulness for one night at their habitual bedtime. Participants completed a 10-minute psychomotor vigilance task and resting-state electroencephalography recording from 22:00 (baseline) to 06:00 at 2-hour intervals. Power spectral and phase-amplitude coupling analyses were conducted. Vigilance during prolonged wakefulness exhibited a gradient deterioration that remained stable until 02:00, then sharply declined at 04:00. At 02:00, the coupling between the frontal delta phase and occipital gamma amplitude significantly increased and showed a significant negative correlation with lapses, potentially indicating a top-down compensatory mechanism. Additionally, increased delta activity in parietal areas was significantly correlated with increased mean reaction time and lapses at 04:00. These findings reveal the dynamic fluctuations of neural activity during prolonged wakefulness and suggest that the disconnection between anterior and posterior brain regions may be one of the critical factors contributing to deterioration in vigilance performance.

睡眠的内稳态调节被认为是警觉性暂时逐渐下降的基础。然而，越来越多的证据表明，警惕性的下降并不遵循睡眠缺失的简单线性轨迹。因此，有必要研究在长时间清醒期间警觉性退化是如何逐渐演变的，并捕捉与这种变化相关的皮层神经活动的时间进展。45名健康的年轻人在他们习惯的就寝时间里经历了一个长时间的清醒。从22:00（基线）到06:00，参与者每隔2小时完成10分钟的精神运动警觉性任务和静息状态脑电图记录。进行了功率谱和相幅耦合分析。在长时间的清醒状态下，警觉性表现出梯度恶化，直到02:00保持稳定，然后在04:00急剧下降。02:00时，额叶δ相位与枕叶gamma振幅的耦合显著增加，且与失忆呈显著负相关，提示可能存在自上而下的代偿机制。此外，顶叶区的δ活动增加与04:00时平均反应时间和失误增加显著相关。这些发现揭示了长时间清醒时神经活动的动态波动，并提示大脑前脑和后脑区域之间的断开可能是导致警觉性下降的关键因素之一。

This study investigated the bioelectric brain activity associated with Zen meditation in an ecologically valid monastic setting, comparing experienced Zen practitioners with non-meditating controls. The experimental group consisted of Vietnamese monks from Truc Lam Tay Thien and Truc Lam Thuong Chieu monasteries, while the control group comprised non-practitioners. EEG data were collected using a portable 4-channel BrainBit Flex cap during both morning and evening meditation sessions, capturing theta (5–8 Hz), alpha (8–13 Hz) and beta (15–30 Hz) frequency bands.

Results

indicate that monks exhibited significantly higher alpha and theta band power during meditation than controls, with no changes in beta power. This pattern distinguishes Zen meditation from other forms, like mindfulness practices, where reductions in beta power are often observed. Notably, there were no significant EEG differences in the brain activity of monks between meditation and mind-wandering states, nor between brief (4-minute) and extended (1.5-hour) meditation sessions, suggesting a high degree of continuity between meditative and non-meditative states in advanced practitioners.

本研究调查了在生态有效的寺院环境中禅宗冥想相关的生物电脑活动，将有经验的禅宗练习者与非禅宗控制组进行比较。实验组由来自trc Lam Tay Thien和trc Lam Thuong Chieu寺庙的越南僧侣组成，而对照组由非修行者组成。在早上和晚上的冥想过程中，使用便携式4通道BrainBit Flex帽收集EEG数据，捕获theta (5-8Hz), alpha （8-13Hz）和beta （15-30Hz）频段。结果：和尚在冥想时表现出明显高于对照组的α和θ波段功率，而β功率没有变化。这种模式将禅宗冥想与其他形式的冥想区分开来，比如正念练习，在正念练习中经常观察到β能量的减少。值得注意的是，在冥想和走神状态之间，在短暂（4分钟）和延长（1.5小时）的冥想过程中，僧侣的大脑活动没有显著的脑电图差异，这表明高级修行者的冥想和非冥想状态之间存在高度的连续性。这些发现有助于理解禅宗冥想背后的神经机制，禅宗冥想似乎培养了一种独特的状态，其特点是放松和持续警觉的结合。通过强调其在心理健康方面的潜在作用，该研究还证明了在自然环境中使用移动脑电图技术进行现场数据收集的有效性，支持超越实验室限制的冥想研究的进步。

When people connect, their heart rates may become synchronized. Research has documented greater interdependence among people from lower socioeconomic status (SES) backgrounds, but little is known about whether greater interdependence also emerges at a physiological level in low-SES contexts. The present laboratory-based study examined physiological linkage (i.e., coordinated changes in interbeat interval on a second-by-second basis) in 48 married couples (96 spouses) from highly diverse SES and racialized backgrounds across two marital interaction contexts (i.e., a conflict and a pleasant conversation). We analyzed both in-phase (i.e., coordinated changes in same direction) and anti-phase (i.e., coordinated changes in opposing directions) linkage. The overall sample size was N = 192 observations (48 couples with four repeated measures: in-phase and anti-phase linkage in conflict and pleasant conversations). Repeated measures analyses showed that, across both conversations, spouses from lower (vs. higher) SES backgrounds showed lower anti-phase and greater in-phase physiological linkage, with the difference in anti-phase linkage being more pronounced. That is, their heart rates were less likely to change in opposite ways and more likely to change in similar ways. These findings provide the first evidence that privileged couples connect differently from less privileged couples at a physiological level, contributing to conversations on how macro-level factors become embedded and embodied in the micro.

当人们相互联系时，他们的心率可能会同步。研究已经证明，社会经济地位（SES）背景较低的人之间的相互依赖性更强，但对于低社会经济地位背景下是否也会在生理层面上出现更强的相互依赖性，我们知之甚少。本研究以实验室为基础，研究了48对来自高度不同社会经济地位和种族背景的已婚夫妇（96对配偶）在两种婚姻互动环境（即冲突和愉快的交谈）中的生理联系（即，每秒钟心跳间隔的协调变化）。我们分析了同相（即同一方向的协调变化）和反相（即相反方向的协调变化）联系。总样本量为N = 192个观察结果（48对夫妇有四个重复测量：冲突和愉快谈话中的同阶段和反阶段联系）。重复测量分析表明，在两种对话中，来自较低（相对于较高）社会经济地位背景的配偶表现出较低的反相生理联系和较高的同相生理联系，反相生理联系的差异更为明显。也就是说，他们的心率不太可能以相反的方式变化，而更可能以相似的方式变化。这些发现提供了第一个证据，证明特权夫妇与不那么特权的夫妇在生理层面上的联系不同，有助于讨论宏观层面的因素如何嵌入和体现在微观层面。

The effects of reward expectation and conceptual unitization during encoding on associative recognition: Evidence from behavior and ERPs 编码过程中奖励期望和概念统一对联想识别的影响：来自行为和erp的证据

Previous studies have shown that both reward expectation and conceptual unitization can promote associative memory performance, but little is known about how reward affects two processes of associative memory retrieval (i.e., familiarity and recollection) and whether reward and conceptual unitization have mutual influence on associative recognition. Therefore, this study aims to explore the separate and mutual role of them on associative recognition and their underlying mechanisms through the R/K paradigm (Experiment 1) and event-related potential (ERP) measures (Experiment 2) under consistent unitization-congruence (UC) (Experiment 1) and inconsistent UC (Experiment 2) conditions. Results showed that, under UC-consistent condition, reward promoted associative recognition performance (Prs) through recollection, while conceptual unitization (compounds vs. noncompounds) impaired overall Prs but increased hit rates with reducing recollection but strengthening familiarity. Additionally, for hits, reward weakened the conceptual unitization effect and reward effect only appeared in noncompounds. Under UC-inconsistent condition, results showed the same reward effect and the opposite unitization effect on Prs as Experiment 1. ERP results revealed that in the test phase, reward effects were found in FN400 on frontal location and LPC on frontal and central location with more positive amplitudes for rewarded stimuli, indicating more semantic unitization processing and cognitive efforts putting into them, and conceptual unitization enhanced Prs through familiarity and recollection processes. And ERP reward effects still just existed in noncompounds. The above results indicated that the mechanisms by which reward and conceptual unitization affected associative recognition changed with UC.

以往的研究表明，奖励期望和概念统一都能促进联想记忆的表现，但关于奖励如何影响联想记忆提取的两个过程（熟悉度和回忆）以及奖励和概念统一是否相互影响联想识别的研究却很少。因此，本研究旨在通过R/K范式（实验1）和事件相关电位（ERP）测量（实验2），探讨两者在一致统一-一致性（实验1）和不一致统一-一致性（实验2）条件下对联想识别的分离和相互作用及其潜在机制。结果表明，在UC-consistent条件下，奖励通过回忆提高了联想识别的表现，而概念统一（化合物与非化合物）降低了整体的联想识别，但增加了命中率，减少了回忆，但增强了熟悉度。此外，对于击中，奖励削弱了概念统一效应，奖励效应只出现在非复合词中。在uc -不一致条件下，结果显示与实验1相同的奖励效应和相反的统一效应。ERP结果显示，在测试阶段，FN400在额叶位置出现奖励效应，LPC在额叶和中央位置出现奖励效应，且奖励刺激的正波幅更大，表明语义统一加工和认知努力投入更多，概念统一通过熟悉和回忆过程增强了pr。而ERP奖励效应只存在于非化合物中。上述结果表明，奖励和概念统一影响联想识别的机制随着UC的发生而改变。

Sleep deprivation (SD) is known to impair cognitive performance, yet its effects on higher-order cognitive control remain poorly understood. This study investigated the impact of 36-hour SD on proactive and reactive control using the AX-Continuous Performance Task (AX-CPT) and event-related potentials (ERP). Thirty-three healthy college students underwent 36 h of continuous SD, with cognitive performance assessed at baseline, following 24 and 36 h of SD. Behavioral results revealed significant impairments in proactive and reactive control, as indicated by increased error rates and longer response times in BX and AY trials, respectively. However, proactive control remained the dominant strategy throughout the SD period, as evidenced by positive Proactive Behavioral Index (PBI) values, smaller P3 and larger CNV amplitudes for cue A, and larger N2 and smaller P3 amplitudes for AY trials. These results provide novel insights into the cognitive mechanisms underlying SD-induced impairments and highlight the robustness of proactive control in sleep-deprived individuals. The findings have practical implications for developing interventions to enhance cognitive performance in high-stakes tasks that require flexible control under SD.

众所周知，睡眠剥夺会损害认知能力，但其对高阶认知控制的影响尚不清楚。本研究利用ax -连续表现任务（AX-CPT）和事件相关电位（ERP）研究了36小时SD对主动和被动控制的影响。33名健康的大学生接受了连续36小时的SD治疗，在24小时和36小时的SD治疗后，以基线水平评估认知表现。行为学结果显示，在BX和AY试验中，主动式和反应性控制方面存在显著损伤，分别表现为错误率增加和反应时间延长。然而，在整个SD期间，主动控制仍然是主导策略，这一点可以从积极的主动行为指数（PBI）值中得到证明，提示A的P3值更小，CNV值更大，而提示A的N2值更大，P3值更小。这些结果为sd诱发损伤的认知机制提供了新的见解，并强调了睡眠剥夺个体主动控制的稳健性。研究结果对开发干预措施以提高在高风险任务中需要灵活控制的认知表现具有实际意义。
