Processing social feedback is essential for establishing appropriate social connections. However, social feedback is not always immediate, and the impact of waiting time on social feedback processing remains unexplored. Using electroencephalography (EEG) and event-related potentials (ERPs), the present study investigated how waiting time affects the N170, reward positivity (RewP), and P3. Participants (N = 36) completed a social evaluation task, awaiting feedback from liked and disliked peers with short (800–1200 ms) or long (5000–6000 ms) waiting times. Participants were more motivated to receive feedback from liked peers, and they rated acceptance from liked peers as more pleasant than rejection. Notably, participants found longer waits more worthwhile when receiving acceptance from liked peers, but less worthwhile when awaiting feedback from disliked peers. EEG results revealed that the RewP was increased for long waiting times for feedback from liked peers, and, conversely, reduced for long waiting times for feedback from disliked peers. Additionally, N170 and P3 were found to be sensitive to waiting time, with larger amplitudes for long compared to short waits. Overall, this study demonstrates that waiting time differentially affects social feedback processing, as reflected by changes in the N170, RewP, and P3. Our findings suggest that increased waiting time does not necessarily reduce reward value; it can enhance it depending on subjective social preferences. The increased N170 and P3 amplitudes during longer waits may indicate heightened attentional and memory demands. This study advances our understanding of the neurocognitive mechanisms underlying social decision-making.

处理社会反馈对于建立适当的社会联系至关重要。然而，社交反馈并不总是即时的，等待时间对社交反馈处理的影响仍未被探索。利用脑电图（EEG）和事件相关电位（ERPs）研究了等待时间对N170、奖励正性（RewP）和P3的影响。参与者（N = 36）完成了一项社会评估任务，等待喜欢和不喜欢的同伴的反馈，等待时间短（800-1200 毫秒）或长（5000-6000 毫秒）。参与者更有动力从喜欢的同伴那里得到反馈，他们认为被喜欢的同伴接受比被拒绝更令人愉快。值得注意的是，参与者发现，在得到喜欢的同伴的认可时，等待更长的时间更值得，但在等待不喜欢的同伴的反馈时，等待更长的时间就不值得了。脑电图结果显示，等待来自喜欢的同伴的反馈时间越长，RewP越高；相反，等待来自不喜欢的同伴的反馈时间越长，RewP越低。此外，N170和P3对等待时间敏感，长等待时的振幅大于短等待时的振幅。总的来说，本研究表明，等待时间对社会反馈加工的影响存在差异，这反映在N170、RewP和P3的变化上。我们的研究结果表明，等待时间的增加并不一定会降低奖励价值；它可以根据主观的社会偏好来增强它。在长时间的等待中，N170和P3振幅的增加可能表明注意力和记忆需求的增加。这项研究促进了我们对社会决策背后的神经认知机制的理解。

Military personnel often encounter situations that can trigger acute stress, which may affect operational performance. Therefore, it is important to examine stress responses in controlled environments to obtain more insights in performance-influencing effects of acute stress. This study investigated the impact of passive heat exposure combined with virtual combat scenarios on cardiovascular and psychophysiological parameters in a controlled setting. Sixty-eight healthy servicemembers were randomized into a low-stress or high-stress condition. Both groups engaged in two virtual combat scenarios. The low-stress group, however, underwent testing under thermoneutral conditions (M_Temp = 22.4°C, M_{RelativeHumidity} = 41.4%) whereas the high-stress group was exposed to passive heat exposure (M_Temp = 35.9°C, M_{RelativeHumidity} = 66.4%) using a portable environmental facility. While virtual combat scenarios alone led to a decrease in heart rate variability (HRV) without affecting heart rate (HR), the addition of passive heat exposure elicited a more pronounced physiological stress response, characterized by significantly higher HR and lower HRV in the high-stress condition. However, no significant changes were observed in respiratory rate, salivary cortisol, or alpha-amylase levels across the conditions, suggesting that there was no activation of either the hypothalamic-pituitary-adrenal or the sympathetic-adrenal-medullary axis. Furthermore, subjective stress and anxiety scores did not differ between conditions, underscoring the physiological nature of the observed changes. Resultantly, the physiological response was likely a thermal reaction rather than an acute stress response. These findings highlight the importance of incorporating environmental stressors into military training protocols to enhance realism and prepare personnel for operational stressors. However, the mild response observed suggests that higher ambient temperatures and longer exposure times may be necessary to evoke a more robust stress response for effective stress inoculation training.

军事人员经常遇到可能引发急性压力的情况，这可能会影响行动表现。因此，在受控环境中检查应激反应以获得对急性应激影响性能的更多见解是很重要的。本研究在受控环境下研究了被动热暴露结合虚拟战斗场景对心血管和心理生理参数的影响。68名健康的军人被随机分为低压力组和高压力组。两个小组都参与了两个虚拟战斗场景。压力小的组,但是,经历了热中性的条件下测试(MTemp = 22.4 °C, MRelativeHumidity = 41.4 %)而高压力集团被暴露在被动热暴露(MTemp = 35.9 °C, MRelativeHumidity = 66.4 %)使用便携式环境设施。虽然虚拟战斗场景单独导致心率变异性（HRV）的降低而不影响心率（HR），但被动热暴露的增加引发了更明显的生理应激反应，其特征是在高应激条件下显着提高HR和降低HRV。然而，在不同的条件下，呼吸频率、唾液皮质醇或α -淀粉酶水平没有明显的变化，这表明下丘脑-垂体-肾上腺或交感神经-肾上腺-髓质轴都没有激活。此外，主观压力和焦虑得分在不同条件下没有差异，强调了观察到的变化的生理性质。因此，生理反应可能是一种热反应，而不是急性应激反应。这些发现强调了将环境压力因素纳入军事训练协议的重要性，以提高现实性并使人员做好应对作战压力因素的准备。然而，观察到的轻微反应表明，更高的环境温度和更长的暴露时间可能需要唤起更强大的应激反应，以进行有效的应激接种训练。

Emotional flexibility refers to an individual's ability to change emotional responses in constantly changing environments to adapt to different situations. This study aims to use the Emotional Switching Task (EST) paradigm, combined with Electroencephalogram (EEG) technology and behavioral experiments, to explore the impact of emotional valence shift directions and preparation effects on the switching cost of emotional flexibility. The results found that when individuals switch from positive emotional valence to positive emotional valence, the switching cost is smaller than other transition directions. In addition, emotional flexibility exhibits a preparation effect, with a 2000 ms preparation time resulting in a smaller switching cost than a 600 ms preparation time. The electrophysiological data, more specifically the N2, CNV, SPN and LPP components, reveal the neural mechanisms by which emotional valence shift direction and preparation time influence emotional flexibility across the three neural computational stages of emotion regulation. This study is beneficial for establishing a potential mechanism model for the switching cost of emotional flexibility.

情绪灵活性是指个体在不断变化的环境中改变情绪反应以适应不同情况的能力。本研究旨在运用情绪转换任务（EST）范式，结合脑电图（EEG）技术和行为实验，探讨情绪效价转移方向和准备效应对情绪灵活性转换成本的影响。结果发现，当个体从积极情绪效价向积极情绪效价转换时，其转换成本小于其他转换方向。此外，情绪灵活性表现出准备效应，2000 ms的准备时间比600 ms的准备时间产生更小的转换成本。电生理数据，特别是N2、CNV、SPN和LPP分量，揭示了情绪价移方向和准备时间在情绪调节的三个神经计算阶段影响情绪灵活性的神经机制。本研究有助于建立情绪灵活性转换成本的潜在机制模型。

Cooperation and competition in social interaction are important to social development. There are many studies examining the neural mechanism underlying these behaviors; however, little is known about the potential role of payoff norms in social interactions. This study introduced two distinct payoff norms: zero-sum (ZS) and non-zero-sum (NZS). In the ZS group, only the player with the highest total score would receive a reward; while in the NZS group, rewards were determined by the combined total score of both players, and individual rewards were prorated according to each player's contribution to the total score. Electroencephalography was used to examine individuals' neural responses during the Chicken Game in these different groups. The behavioral findings revealed a higher rate of cooperation in the NZS group compared to the ZS group. Aggressive behaviors from opponents elicited larger feedback-related negativity (FRN) and lower P300 amplitudes in both groups. Notably, larger FRN and smaller P300 amplitudes were elicited by participants' aggressive behaviors compared to their cooperative behaviors in the ZS group, whereas larger P300 amplitudes were elicited by aggressive behaviors compared to cooperative behaviors in the NZS group. Additionally, a greater theta event-related synchronization (ERS) was observed solely when participants exhibited aggression in the NZS group. The type of group moderated the association between posterior theta-ERS and cooperative rates. Specifically, theta-ERS was negatively associated with cooperative rates in the NZS group, whereas a reversed association was found in the ZS group. These findings provide valuable insights into the neurobiological foundations of cooperation under different economic payoff norms.

The present study tested the effect of social comparison on effort-related cardiovascular responses. Specifically, we investigated how effort levels are influenced when individuals compare themselves to significantly better peers versus similar or slightly better peers. 43 participants played five-minute video games while displaying the scores of peers who were similar, slightly better, or significantly better, in addition to a control condition without peer scores. Effort-related cardiovascular responses were measured using the pre-ejection period during both game and baseline conditions. Results revealed that the pre-ejection period was stronger when participants competed with peers who were similar or slightly better compared to those who were significantly better or in the control condition. These findings highlight the role of social comparison in modulating effort-related cardiovascular responses, emphasizing the moderating role of the ability gap between the individual and the comparison source on the effect of social comparison on effort.

本研究测试了社会比较对努力相关心血管反应的影响。具体来说，我们调查了当个体将自己与明显更好的同伴相比，与相似或稍微更好的同伴相比，努力水平是如何受到影响的。43名参与者玩了五分钟的视频游戏，同时显示同伴的得分，这些同伴的得分相似，稍好，或明显更好，此外还有一个没有同伴得分的控制条件。在游戏和基线条件下，使用弹射前的时间测量与努力相关的心血管反应。结果显示，当参与者与那些明显更好或处于控制条件下的同龄人竞争时，他们的前弹射期更强。这些发现强调了社会比较在调节努力相关心血管反应中的作用，强调了个体与比较源之间的能力差距对社会比较对努力的影响的调节作用。

Perceptual fluency affects recognition memory under deep encoding conditions promoting recollection: Evidence from an ERP study using letter-segregated method 在深度编码条件下，知觉流畅性影响识别记忆，促进回忆：来自字母分离方法的ERP研究证据。

Perceptual fluency can increase familiarity of some of the items in recognition tests and enhance attributions of these items to the past. It is not clear, however, whether perceptual fluency can influence recognition under conditions promoting recollection-based memory. To this end, we performed a systematic replication of a study by Lucas and Paller (2013) using a letter-segregated method. We recorded ERPs while participants performed recognition task in letter segregated (LS) blocks, in which new words were always composed of different letters than old words, and in letter non-segregated (LNS) blocks, in which half of the new words came from the same letter pool as the studied words (new related words), and the other half came from the other pool (new unrelated words). Unlike the Lucas and Paller study, deep encoding promoted more recollection-based memory. In the LNS blocks, the comparison between old and new unrelated words revealed early (180–260 ms) P200 old/new effect, showing that recognition can be supported by an early discrimination of perceptual differences between studied and unstudied test probes. The relatively large hit rates and relatively high sensitivity measures, as well as the late (500–700 ms) LPC old/new effects in both blocks, indicated high levels of recollection for old words. Still, recognition memory was more accurate in the LS blocks, whereas in the LNS blocks there were more false alarms for new related than for new unrelated words. This suggests that perceptual fluency derived from low-level information may influence not only familiarity, but also recollection-based memory judgments.

知觉流畅性可以增加识别测试中某些项目的熟悉度，并增强这些项目对过去的归因。然而，在促进基于回忆的记忆的条件下，知觉流畅性是否会影响识别尚不清楚。为此，我们使用字母分离方法对Lucas和Paller（2013）的研究进行了系统的复制。我们记录了被试在字母隔离组（LS）和非字母隔离组（LNS）中执行识别任务时的erp，其中LS组中，新单词总是由不同的字母组成，而LNS组中，一半的新单词来自与学习单词相同的字母池（新的相关单词），另一半来自另一个池（新的不相关单词）。与卢卡斯和帕勒的研究不同，深度编码促进了更多基于回忆的记忆。在LNS块中，新旧不相关词的比较显示出早期（180-260 ms） P200的旧/新效应，表明对已研究和未研究测试探针之间感知差异的早期区分可以支持识别。相对较高的命中率和相对较高的灵敏度，以及两个区块的LPC后期（500-700 ms）旧/新效应，表明对旧单词的回忆水平较高。尽管如此，LS组的识别记忆更准确，而LNS组对新的相关词的误报多于对新的不相关词的误报。这表明，来自低水平信息的知觉流畅性不仅会影响熟悉度，还会影响基于回忆的记忆判断。

Utilizing movement-related potentials to monitor cognitive rehabilitation in individuals with central nervous system disorders: A review 利用运动相关电位监测中枢神经系统疾病患者的认知康复：综述。

In current neuroscience, there is a pressing need to evaluate the effectiveness of treatments for motor and cognitive disorders. In addition, there is a gap in the literature on assessing this type of rehabilitation. This review proposes using Movement-Related Potentials (MRPs) as a relevant marker for such evaluations. The method employed involves administering a psychomotor task known as the Skilled Performance Task (SPT). Originally described in 1980 by Papakostopoulos, the SPT requires specific abilities, such as bimanual coordination, adaptive programming, and precise timing. Subjects must start and stop a sweep on an oscilloscope screen with accurate timing, receiving immediate feedback that aids in performance improvement. This self-paced, goal-directed, and interactive task ensures continuous engagement and learning. Suitable for all ages, the SPT provides real-time feedback and demands constant attention and reprogramming of movements, making it an effective tool for assessing and promoting cognitive rehabilitation through neuroplasticity. The originality of this task lies in the ability to obtain, with a single motor act, a series of potentials that represent different stages of the processing of a goal-directed and self-initiated action.

在当前的神经科学领域，迫切需要对运动和认知障碍的治疗效果进行评估。此外，在评估这类康复的文献中还存在空白。本综述建议使用运动相关电位（MRP）作为此类评估的相关标记。所采用的方法包括执行一项称为 "技能表现任务"（SPT）的精神运动任务。SPT 最初由 Papakostopoulos 于 1980 年描述，需要特定的能力，如双臂协调、适应性编程和精确计时。受试者必须在示波器屏幕上开始和停止扫描，并准确掌握时间，同时接受即时反馈，以帮助提高成绩。这种自定进度、目标引导和互动的任务可确保持续参与和学习。SPT 适合所有年龄段的人，它能提供实时反馈，并要求持续关注和重新编程动作，是通过神经可塑性评估和促进认知康复的有效工具。这项任务的独创性在于，通过单个动作就能获得一系列电位，这些电位代表了目标引导和自我启动动作的不同处理阶段。与这一任务相关的 MRP 包括 Bereitschaftspotential (BP)、Motor Cortex Potential (MCP)、N100、P200、Skilled Performance Positivity (SPP) 和 Post-Action Negativity (PAN)。本研究从认知康复的角度重新诠释了之前对患有各种中枢神经系统疾病的儿童和成人所做的研究，为利用 MRPs 的神经康复技术提供了新的见解。

Background

An elevated startle reflex in anticipation of unpredictable threat has been associated with concurrent anxiety disorders. However, only one study to date has examined whether startle potentiation in anticipation of unpredictable threat predicts the development of anxiety disorders.

Method

In a community sample of 309 adolescents, we examined whether the startle reflex in anticipation of predictable or unpredictable threat at age 15 predicted onset of generalized anxiety disorder (GAD) and social anxiety disorder (SAD) at age 18. To evaluate the specificity of these relationships, we also examined the development of depressive disorders. Startle reflex was measured using the no, predictable, and unpredictable threat task at age 15. Semi-structured diagnostic interviews were administered at both waves to assess lifetime anxiety disorders and depression.

Results

Average startle reflex and startle potentiation to unpredictable, but not predictable, threat at age 15 predicted GAD at age 18, independent of lifetime GAD through age 15 and lifetime depression through age 18. Startle responses at age 15 did not predict SAD or depression at age 18.

Conclusions

The present study suggests that elevated startle potentiation in anticipation of unpredictable threat is a risk factor for the development of GAD in adolescence.

背景：预料到不可预测的威胁时惊吓反射升高与并发焦虑症有关。然而，到目前为止，只有一项研究调查了在预测不可预测的威胁时的惊吓增强是否能预测焦虑症的发展。方法：在309名青少年的社区样本中，我们检查了15岁时预期可预测或不可预测威胁的惊吓反射是否预测18岁时广泛性焦虑障碍（GAD）和社交焦虑障碍（SAD）的发作。为了评估这些关系的特异性，我们还研究了抑郁症的发展。惊吓反射是在15岁时通过无、可预测和不可预测威胁任务来测量的。半结构化的诊断访谈在两个波中进行，以评估终身焦虑症和抑郁症。结果：平均惊吓反射和惊吓增强对15岁时不可预测但不可预测的威胁预测18岁时的广泛性焦虑症，独立于15岁前的终生广泛性焦虑症和18岁前的终生抑郁症。15岁时的惊吓反应并不能预测18岁时的SAD或抑郁症。结论：本研究表明，预期不可预测的威胁时惊吓增强是青少年广泛性焦虑症发展的一个危险因素。

Brain-body interactions play a crucial role in the perceptual and cognitive processing of external stimuli. Previous research has examined how cardiac phases (systole, diastole) and respiratory phases (inhalation, exhalation) influence various psychological functions, though findings on their impact on auditory processing remain inconsistent. This study investigated whether cardiac and respiratory phases affect auditory ERP components, specifically N1 and P2. To control for cardiac-related artifacts, pure tones (70 dB) and silent stimuli (0 dB) were presented in alternating, randomized intervals, and ERP difference waveforms were computed by subtracting waveforms elicited by silent stimuli from those elicited by tones. Two experiments were conducted with different participants: watching a video while ignoring the tones (Experiment 1) or pressing a button as quickly as possible in response to the tones while watching the video (Experiment 2). Results showed no significant differences in N1 amplitude between cardiac or respiratory phases. P2 amplitude was significantly larger at diastole than systole, although the effect size was small (d_z = 0.26). For respiratory phases, P2 amplitude was greater during exhalation than inhalation when participants ignored the tones (d_z = 0.35), but this effect disappeared when they attended to the tones. These findings suggest that visceral afferent signals may influence auditory processing by modulating attentional resource allocation across different cardiac and respiratory phases.

Attenuation of auditory Tb and N200 in response to self-modulated tones during continuous actions reflects the prediction of action consequences

Event-related potentials (ERPs) in response to tones modulated by one's own continuous actions (i.e., turning a steering wheel) are attenuated compared to those in response to tones presented externally. We investigated whether the ERP attenuation by continuous actions reflects a prediction of action consequences or a decrease in attentional resources available for auditory processing during the performance of actions. To compare these hypotheses, ERPs were measured in two conditions. In the modulation condition, participants modulated the pitch of tones by turning a steering wheel (i.e., frequent regular tones), and tones with an inconsistent pitch were occasionally presented among the regular tones (i.e., infrequent irregular tones). In the listening condition, participants listened to the same tones as in the modulation condition without performing any action. We expected that the irregular tones would elicit N2 and P3 (i.e., prediction errors) and their amplitudes should increase in the modulation than listening conditions, if more precise prediction was generated based on continuous actions; in contrast, they should decrease in the modulation than listening conditions, if attentional resources available for auditory processing decreased during continuous actions. The results showed that the amplitudes of Tb and N200 to regular tones decreased in the modulation than listening conditions, replicating the previous finding. Importantly, the amplitudes of N2 and P3 to irregular tones increased in the modulation than listening conditions. These results indicate that more precise prediction of action consequences underlies the ERP attenuation during continuous actions, which may contribute to efficient action adjustments in everyday life.
