Self-referential information holds an advantage in conflict processing, manifested as a reduction of the congruency effect. Despite investigations into this phenomenon via event-related potentials, the underlying neuro dynamics remain elusive. Additionally, it remains contentious whether the modulation of attentional resources is specific to the self or driven by conflict. To elucidate these matters, we employed electroencephalography to record the cerebral activity of 30 healthy individuals engaged in a modified Stroop task. The behavioral outcomes demonstrated that self-referential information reduces the congruency effect. Time-frequency analysis revealed that self-reference condition elicited increase theta event-related synchronization (ERS) and decrease event-related desynchronization (ERD) compared to non-self-reference condition. The incongruent condition elicited increase theta ERS and beta ERD compared to congruent condition. Notably, in the incongruent condition, self-reference condition elicited increased alpha ERD compared to the non-self-reference condition. Spectral MVPA results showed that conflict can be successfully decoded in the theta band, but not in the alpha and beta bands. Interestingly, during the theta band decoding, in the self-reference condition, conflicts were identified earlier compared to non-self-reference condition. Furthermore, self-referential information was successfully decoded across the theta, alpha, and beta bands.

自我参照信息在冲突加工中具有优势，表现为一致性效应的减弱。尽管通过事件相关电位对这一现象进行了研究，但潜在的神经动力学仍然难以捉摸。此外，注意力资源的调节是特定于自我还是由冲突驱动仍然存在争议。为了阐明这些问题，我们采用脑电图记录了30名参与改良Stroop任务的健康个体的大脑活动。行为结果表明，自我参照信息降低了一致性效应。时间-频率分析表明，与非自我参照条件相比，自我参照条件诱发的事件相关同步（ERS）增加，事件相关非同步（ERD）减少。与一致条件相比，不一致条件诱发的β ERD和β ERS增加。值得注意的是，在不一致条件下，与非自我参照条件相比，自我参照条件诱发的α ERD增加。光谱MVPA结果表明，冲突在θ波段可以成功解码，但在α和β波段不能成功解码。有趣的是，在theta波段解码过程中，自我参照条件下的冲突比非自我参照条件下更早被识别出来。此外，自我参照信息在theta， alpha和beta波段上被成功解码。

Sustaining attention is a key ability not only for adults in contexts such as driving or monitoring systems, but also for children in educational settings, where it is closely linked to long-term academic achievement. The present study aimed to develop an EEG-based measure of vigilance during a sustained attention task and to use it to identify distinct trajectories of vigilance over time in a sample of children with and without ADHD.

The measure was developed using multiple regression and captures time-on-task-related changes in the EEG power spectrum. In typically developing children, it is characterized by an increase in theta, alpha and beta activity and a decrease in gamma activity over time. A k-means cluster analysis identified distinct vigilance trajectories, and the corresponding subgroups of children differed both in various performance metrics and in the number of ADHD symptoms. The normative pattern, characterized by a steadily rising trajectory over time, was associated with better performance, whereas atypical patterns showing pronounced declines either early or late in the task were linked to comparatively weaker performance.

The identified vigilance profiles point to different mechanisms of sustained attention regulation in children and may help to detect these differences at the individual level, thereby paving the way for personalized interventions.

保持注意力是一项关键能力，不仅适用于驾驶或监控系统等环境中的成年人，也适用于教育环境中的儿童，因为它与长期学业成绩密切相关。本研究旨在开发一种在持续注意力任务中基于脑电图的警觉性测量方法，并使用它来识别患有和非ADHD儿童样本中不同的警觉性轨迹。该方法采用多元回归方法，捕捉脑电功率谱中与任务时间相关的变化。在正常发育的儿童中，随着时间的推移，它的特征是theta， alpha和beta活动增加，gamma活动减少。k-均值聚类分析确定了不同的警觉性轨迹，相应的儿童亚组在各种表现指标和ADHD症状的数量上都存在差异。随着时间的推移，以稳定上升轨迹为特征的标准模式与更好的表现有关，而在任务的早期或后期表现出明显下降的非典型模式与相对较弱的表现有关。已确定的警惕性特征指出了儿童持续注意力调节的不同机制，并可能有助于在个体水平上发现这些差异，从而为个性化干预铺平道路。

This study investigated the electrophysiological correlates of the impact of within- and cross-language lexical-semantic information on the way to forward and backward translation articulation in unbalanced Chinese-English bilinguals. Participants were tasked with a bilingual flanker paradigm, in which the language congruency (congruent vs. incongruent) and semantic relatedness (i.e., semantically related vs. unrelated vs. identical) between the targets and flankers were manipulated, and the behavioral and event-related potentials (ERPs) data were measured to track the relative contributions of these two variables. Behavioral data revealed faster response time and higher error rate for forward than for backward translation. Additionally, bilinguals exhibited a higher error rate and slower response time for congruent than for incongruent contexts. Furthermore, ERP data revealed that both forward and backward translation processes were impacted by the cross-language (incongruent) lexical information of the semantically identical flanker words, as reflected by the modulation of the P200 (150–300 ms) component. Meanwhile, the forward and backward translation processes benefited from the semantic representation of Chinese flanker words, as reflected by less negative N400 (300–600 ms) amplitudes for semantically identical condition than for unrelated control. More importantly, the activation induced by Chinese flankers also interactively spread to the semantically related categories, as reflected by less negative N400 amplitudes for related condition than for unrelated control. Meanwhile, identical condition also elicited less negative N400 amplitudes than unrelated controls regardless of translation directions when the flankers were English words. These findings were interpreted in the framework of the Multilink model, according to which translation articulation involves both within- and cross-language lexical-semantic activation regardless of translation directions, and the above processes are modulated by language contexts.

本研究探讨了内语和跨语词汇语义信息对不平衡汉英双语者前后翻译发音方式影响的电生理机制。被试采用双语侧卫范式，对被试和侧卫之间的语言一致性（一致vs不一致）和语义相关性（即语义相关vs不相关vs相同）进行控制，并测量行为和事件相关电位（erp）数据，以追踪这两个变量的相对贡献。行为数据显示，正向翻译比反向翻译的响应时间更快，错误率更高。此外，双语者对一致语境的错误率高于对不一致语境的错误率和反应时间。此外，ERP数据显示，前向和后向翻译过程都受到语义相同的侧边词的跨语言（不一致）词汇信息的影响，这反映在P200（150-300 ms）分量的调制上。同时，正向和反向翻译过程受益于汉语侧边词的语义表征，语义相同条件下的负N400（300-600 ms）振幅小于不相关条件下的负N400。更重要的是，汉语侧读诱发的激活也交互地传播到语义相关的类别，相关条件的负N400振幅小于不相关条件。与此同时，无论翻译方向如何，当侧边为英语单词时，相同条件下的N400负向振幅也低于不相关对照。这些发现是在多链接模型的框架下解释的，根据该模型，无论翻译方向如何，翻译发音都涉及语言内和跨语言的词汇语义激活，并且上述过程受语言语境的调节。

Effects of target probability on motor preparation and execution 目标概率对运动准备和执行的影响。

The aim of the present study was to assess the effects of motor target probability on the associations between pro-active motor preparation as reflected by negative slow potentials (NSPs), motor execution as reflected by response-related potentials (RRPs), and performance monitoring as reflected by correct response negativity (Nc). It was hypothesized that if ongoing increases/decreases in preparation induced by target expectation modulate motor execution and monitoring, there would be an association between the effects of motor target probability on NSPs and RRPs/Nc.

Electroencephalographic (EEG) signals were recorded in young adults while they produced simultaneous responses with the two hands to Go trials in auditory Go/NoGo tasks with different target probabilities (P = 0.15, P = 0.50, and P = 0.85). NSPs and RRPs were analyzed at the midline and bilateral motor regions. Nc was analyzed at medial frontal electrodes.

It was found that the effects of probability on NSPs were lateralized: At the left motor cortex NSPs were expressed for the low and high probabilities, mirroring response speeding, whereas at the right motor region NSPs were not pronounced for higher (P = 0.50 and P = 0.85) probabilities. Bi-lateral RRPs were larger for low- than equal- and high-probability targets and correlated positively with left-hemisphere NSPs but negatively with right-hemisphere NSPs. Nc did not depend on target probability.

The lateral and functional NSP/RRP asymmetry and their correlations suggest that the interaction between movement preparation and execution is modulated by hemispheric specialization in motor control such that movement execution in enhanced inhibition context is potentiated by the left hemisphere, and movement execution in response generation context is controlled by proactive inhibition in the right hemisphere. The effects of target probability on performance monitoring are not clearly demonstrated by Nc analysis in Go/NoGo tasks.

本研究的目的是评估运动目标概率对负慢电位（NSPs）反映的主动运动准备、反应相关电位（rrp）反映的运动执行和正确反应负性（Nc）反映的表现监测之间的关联的影响。假设如果目标预期引起的准备的持续增加/减少调节运动执行和监测，那么运动目标概率对nsp和rrp /Nc的影响之间存在关联。在不同目标概率的听性Go/NoGo任务中，记录年轻人双手同时做出反应的脑电图（EEG）信号（P = 0.15,P = 0.50,P = 0.85）。在中线和双侧运动区分析nsp和rrp。在内侧额电极处分析Nc。结果发现，概率对NSPs的影响是横向的：在左侧运动皮层，NSPs在低概率和高概率下表达，反映了反应速度，而在右侧运动区域，NSPs在高概率下不表达（P = 0.50和P = 0.85）。双侧rrp在低概率靶点比等概率靶点和高概率靶点更大，与左半球NSPs呈正相关，与右半球NSPs负相关。Nc不依赖于目标概率。NSP/RRP的横向和功能性不对称及其相关性表明，运动准备和执行之间的相互作用是由运动控制的半球特化调节的，因此，在增强抑制环境下的运动执行由左半球加强，而在反应产生环境下的运动执行由右半球的主动抑制控制。在Go/NoGo任务的Nc分析中，目标概率对性能监测的影响并没有得到明确的证明。

Adaptive control refers to the dynamic regulation of cognitive processes in response to changing environmental demands. Previous studies demonstrated that the proportion of task switches or response variations can induce adaptive control. However, the extent to which adaptive control is transferred across different contexts remains poorly understood. The present study employed a confound-minimized design comprising two inducer contexts (one with 100 % response repeats and the other with 100 % response changes within a series of task-repeat trials preceding task-switch trials) and a diagnostic list with 50 % response changes. Event-related potentials (ERP) results revealed that: (1) both cue-locked switch-related positivity and stimulus-locked switch-related negativity were attenuated in the response-change inducer context compared to the response-repeat inducer context; and (2) in the diagnostic list, the influence of the inducer context was exclusively observed in the cue-locked P3 component. These results indicate that adaptive control triggered by the high frequency of response changes during task-repetition trials can be transferred to a different context and can modulate the proactive control of task switching in the new context.

自适应控制是指认知过程对环境需求变化的动态调节。以往的研究表明，任务切换或反应变化的比例可以诱导自适应控制。然而，适应性控制在不同背景下的转移程度仍然知之甚少。本研究采用最小化混淆设计，包括两个诱导上下文（一个具有100% %的反应重复，另一个在任务切换试验之前的一系列任务重复试验中具有100% %的反应变化）和一个具有50% %反应变化的诊断列表。事件相关电位（ERP）结果显示：(1)与反应-重复诱导相比，在反应-改变诱导情境下，提示锁定开关相关的正性和刺激锁定开关相关的负性均有所减弱；(2)在诊断列表中，诱导剂上下文的影响仅在线索锁定的P3组分中观察到。这些结果表明，任务重复实验中高频率的反应变化触发的自适应控制可以转移到不同的情境中，并可以调节新情境中任务切换的主动控制。

Physiological arousal during encoding predicts emotional memory: An aging study of phasic and tonic skin conductance activity 编码期间的生理唤醒预测情绪记忆：一项关于皮肤电导活动的相位和强直的衰老研究

It is widely understood that declarative memory and emotion are interconnected, although they are differentially affected by aging. However, the contributions of various aspects of physiological arousal to emotional memory, as well as the roles of valence and age in these relationships, remain unknown. This study aimed to understand the relationship between various aspects of physiological arousal and memory in younger and older adults by examining phasic and tonic skin conductance activity during an emotional verbal learning task. We recruited 26 younger adults (aged 18–35) and 24 older adults (aged 55–89), asking them to encode and recall a list of positive, negative, and neutral words across three learning trials while their skin conductance activity was measured, and to recall the words again after 10 min. We found that both groups recalled more positive and negative words than neutral words in the delayed recall trial. A positive valence effect on memory specific to the encoding phase also emerged, which aligned with a significant phasic skin conductance response (SCR) to positive words. The phasic SCR while encoding positive words predicted the subsequent recall of positive words, while tonic skin conductance level, which was lower in older adults, predicted retention of negative words after the 10-minute delay. These findings suggest that physiological arousal during encoding predicts subsequent emotional memory across different ages, with phasic and tonic arousal making the greatest contributions to positive and negative memories, respectively. Age may differentially influence tonic arousal, which affects memory, particularly for negative stimuli.

人们普遍认为陈述性记忆和情绪是相互联系的，尽管它们受年龄的影响不同。然而，生理唤起对情绪记忆的各个方面的贡献，以及效价和年龄在这些关系中的作用，仍然未知。本研究旨在通过研究情绪性言语学习任务中皮肤电导活动的相位性和紧张性，了解年轻人和老年人生理唤醒与记忆之间的关系。我们招募了26名年轻人（18-35岁）和24名老年人（55-89岁），要求他们在三个学习试验中编码和回忆一系列积极的、消极的和中性的单词，同时测量他们的皮肤电导活动，并在10分钟后再次回忆这些单词。我们发现，在延迟回忆试验中，两组人都能回忆起更多的积极词汇和消极词汇。编码阶段对记忆的正效价效应也出现了，这与对积极词汇的显著相性皮肤电导反应（SCR）一致。编码积极词汇时的相位SCR预测了随后对积极词汇的回忆，而老年人皮肤电导水平较低，预测了10分钟后对消极词汇的记忆。这些发现表明，编码过程中的生理唤醒预测了不同年龄段的情绪记忆，其中，相位唤醒和紧张性唤醒分别对积极记忆和消极记忆贡献最大。年龄对滋补性唤醒的影响可能不同，滋补性唤醒会影响记忆，尤其是负面刺激。

The phasic SCR while encoding positive words predicted the subsequent recall of positive words, while tonic skin conductance level, which was lower in older adults, predicted retention of negative words after the 10-minute delay. These findings suggest that physiological arousal during encoding predicts subsequent emotional memory across different ages, with phasic and tonic arousal making the greatest contributions to positive and negative memories, respectively. Age may differentially influence tonic arousal, which affects memory, particularly for negative stimuli.</div></div>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":"217 ","pages":"Article 113259"},"PeriodicalIF":2.6,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145222989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During visual search, when targets are defined by specific categories, category-based attentional templates (CATs) enhance search efficiency by being pre-activated and modulated by their underlying category frameworks, thereby facilitating the detection of target objects. Previous studies employing the Rapid Serial Probe Presentation (RSPP) paradigm (20 Hz sampling rate) lacked the temporal resolution to continuously track CAT pre-activation dynamics. To address this, we used steady-state visual evoked potentials (SSVEPs) to capture real-time dynamics of CAT pre-activation, improving temporal resolution by 50 times (from 50 ms to 1 ms), enabling the detection of previously inaccessible transient neural processes. SSVEPs and multivariate pattern analysis (MVPA) revealed distinct pre-activation time courses for different CAT frameworks. Specifically, prototype-based CATs (involving perceptual similarity) were pre-activated earliest in posterior visual regions (1808 ms pre-target), followed by semantic-based CATs (involving experience and learning) in anterior temporal networks (1460 ms pre-target), and strategy-based CATs (involving learning) engaging prefrontal control systems last (359 ms pre-target). By uncovering the temporal hierarchy of CAT pre-activation across different cortical systems, our findings refine predictive coding theory, demonstrating how category frameworks shape the temporal dynamics of anticipatory attention and guide CAT pre-activation during visual search.

在视觉搜索过程中，当目标被定义为特定类别时，基于类别的注意模板通过其潜在类别框架的预激活和调制来提高搜索效率，从而促进目标对象的检测。以往采用快速串行探针呈现（RSPP）范式（20 Hz采样率）的研究缺乏持续跟踪CAT预激活动态的时间分辨率。为了解决这个问题，我们使用稳态视觉诱发电位（ssvep）来捕捉CAT预激活的实时动态，将时间分辨率提高了50倍（从50 ms提高到1 ms），从而能够检测到以前无法访问的瞬态神经过程。ssvep和多元模式分析（multivariate pattern analysis， MVPA）显示，不同CAT框架的预激活时间过程存在差异。具体而言，基于原型的cat（涉及感知相似性）在后视区域最早被预激活（1808 ms前目标），其次是基于语义的cat（涉及经验和学习）在后颞叶网络（1460 ms前目标），最后是基于策略的cat（涉及学习）参与前额叶控制系统（359 ms前目标）。通过揭示不同皮层系统中CAT预激活的时间层次，我们的发现完善了预测编码理论，展示了类别框架如何塑造预期注意的时间动态，并指导视觉搜索过程中的CAT预激活。

Psychophysiological research requires choices at every stage, from theory and construct definition to task design, preprocessing, and statistical modeling. Because many of these choices are defensible, a single research question can yield a range of plausible results, complicating inference, transparency, and replicability. This special issue showcases how multiverse analyses can systematically evaluate reasonable alternatives and their influence on outcomes in psychophysiology. Multiverse analyses treat datasets as one possible outcome among many, mapping how decisions shape effect estimates and subsequent inferences. This special issue illustrates multiverse thinking across four domains: (1) hypothesis and construct operationalization, including comparisons of contradictory theoretical accounts and alternative psychophysiological indices; (2) experimental design and task selection, clarifying when effects generalize across paradigms versus depend on task context; (3) data processing pipelines, highlighting which preprocessing steps impact data quality and which are comparatively benign; and (4) statistical models, testing the stability of findings across analytic specifications. Collectively, these contributions provide practical guidance for planning, executing, and transparently reporting multiverse analyses in psychophysiology. This introduction to the special issue offers a roadmap for integrating conceptual and analytic multiverses, emphasizing principled decision making, explicit justification of alternatives, and weighting evidence across analyses. Adopting a multiverse perspective from study conception through analysis can strengthen theoretical precision, identify fragile or robust effects, reconcile discrepant literatures, and improve reproducibility. Multiverse practices can ultimately enhance the robustness, rigor, and interpretability of psychophysiological science and support cumulative knowledge building.

心理生理学研究需要在每个阶段进行选择，从理论和构造定义到任务设计、预处理和统计建模。因为这些选择中的许多都是站得住的，一个单一的研究问题可以产生一系列似是而非的结果，使推理复杂化，透明度和可复制性。本期特刊展示了多元宇宙分析如何系统地评估合理的选择及其对心理生理学结果的影响。多元宇宙分析将数据集视为众多可能结果中的一种，绘制决策如何影响影响估计和随后的推论。这期特刊从四个方面阐述了多元宇宙思维：(1)假设和构造操作化，包括比较相互矛盾的理论解释和不同的心理生理指标；(2)实验设计和任务选择，澄清效应是跨范式的还是依赖于任务情境的；(3)数据处理管道，突出显示哪些预处理步骤会影响数据质量，哪些相对良性；(4)统计模型，检验各分析规范结果的稳定性。总的来说，这些贡献为计划、执行和透明地报告心理生理学中的多元宇宙分析提供了实用指导。这篇特刊的介绍为整合概念和分析的多元宇宙提供了一个路线图，强调原则性的决策制定，明确的替代理由，以及在分析中权衡证据。通过分析，从研究概念出发，采用多元宇宙视角，可以提高理论精度，识别脆弱或稳健效应，调和文献差异，提高可重复性。多元宇宙实践最终可以增强心理生理科学的健壮性、严谨性和可解释性，并支持累积知识的建立。由于心理生理学数据本质上是复杂和多方面的，研究人员在进行心理生理学研究时必须进行广泛的决策。选择出现在每个阶段——从定义任务参数和选择心理生理成分，到确定预处理管道和统计分析。因此，单个研究问题可以通过许多合理的研究设计和分析方法进行测试，每个研究设计和分析方法可能产生不同的结果（Clayson, 2024； Gelman和Loken， 2014）。大量同样站得住脚的选择会让人感到不知所措。这使得评估可复制性的工作变得复杂，并且当研究结果不同时，解释研究结果变得具有挑战性。本期特刊展示了通过使用多元宇宙分析直接解决这些挑战的文章。多元宇宙分析通过系统地检查实验和分析灵活性的影响，为解决心理生理学研究人员面临的无数决策提供了一个强大的框架。多元宇宙分析是指应用一系列合理的分析来研究一种现象（Harder, 2020; Steegen et al., 2016），强调不同的决策如何影响研究结果。多元宇宙方法不是将数据视为产生一个确定的结果，而是认识到原始数据可以导致许多可能的数据集和结果，这取决于分析过程中的选择（Steegen et al., 2016）。通过应用一系列合理的决策，研究人员可以评估其发现的稳健性，确定哪些方法选择会对结果产生有意义的影响，并提高报告的透明度（Harder, 2020； Steegen等人，2016）。鉴于其工作流程中嵌入的决策点的绝对数量，心理生理学研究特别适合于多元宇宙分析（Clayson, 2024）。例如，研究人员必须决定哪种心理生理学方法或反应最能操作他们感兴趣的结构，哪种任务设计最有效地引出该反应，以及如何建立和实现数据处理管道。然后，即使在单一的“最终”数据集中，不同的统计分析决策也可以产生可能结果的“多元宇宙”（cred和菲利普斯，2017；Steegen等人，2016）。本期特刊强调了多元宇宙分析在心理生理学研究中的多功能性、优点和成功。在假设和构造操作化、实验设计和任务选择、数据预处理和统计建模等领域，本文展示了多元宇宙视角如何增强心理生理科学的可靠性、可重复性和可解释性。

Slow gentle stroking of the hairy skin, also called affective touch, has both psychological (i.e., pleasantness of the sensation, improvement of mood state) and physiological (e.g., decrease in heart rate) effects. These effects show considerable individual differences; temporal stability of the individual responses is implicitly assumed in the literature but it has never been empirically investigated. 57 young individuals participated in a preregistered study that assessed experiential and physiological effects of slow (3 cm/s) and fast (30 cm/s) stroking delivered on their forearms two times (eight weeks apart). Pleasantness of the skin sensation showed considerable temporal stability (r = 0.73, p < .001), whereas improvement of mood state was less stable over time (r = 0.53, p < .001). Actual (heart rate, skin conductance level, respiratory rate, skin temperature) and perceived (heart rate, respiratory rate, skin temperature) physiological responses to slow stroking were characterized only by moderate stability. Finally, a considerable discordance between actual responses and their perceived counterparts was found. In conclusion, pleasantness of slow stroking can be considered a trait-like characteristic; changes in mood state and physiological responses are less stable, i.e., they might be substantially impacted by situational factors.
