Category-selectivity is a ubiquitous property of high-level visual cortex manifested in distinct cortical responses to faces, objects, and scenes. These signatures emerge early during visual processing, with each category sensitive to specific types of visual information at different time points. However, it is still not clear what information is extracted during early scene-selective processing, as scenes are rich, complex, and multidimensional stimuli. Here, we tested the hypothesis that early scene-selective activity involves global processing by examining the impact that scene inversion has on visually-evoked Event-Related Potentials (ERPs), particularly the scene-selective P2 component (peaking around 220 ms post-stimulus onset). We recorded ERPs from participants as they were viewing images of faces, objects, and scenes. Images were presented in both upright and inverted orientations and spanned a wide range of category dimensions and properties, preventing the possibility of salient image properties influencing the results. Replicating previous studies, P2 was found to be the first scene-selective component, with higher amplitude in response to scenes compared to faces and objects. Inversion had a clear effect on P2, with a decrease in its amplitude to inverted scenes. No scene inversion effects were observed on P1 and N1, the earlier visually-evoked components. Conversely, face inversion impacted all three components, while inverting objects had no effect on any of the three components. The current findings support the notion that P2 indexes scene-selective processing and suggest that global scene information is extracted at the P2 time window

类别选择性是高级视觉皮层普遍存在的特性，表现在皮层对面孔、物体和场景的不同反应中。这些特征出现在视觉处理的早期，每一类在不同的时间点对特定类型的视觉信息敏感。然而，由于场景是丰富、复杂和多维的刺激，目前尚不清楚在早期场景选择处理中提取了哪些信息。在这里，我们通过检查场景反转对视觉诱发的事件相关电位（ERPs）的影响，特别是场景选择性P2成分（在刺激开始后220毫秒左右达到峰值），验证了早期场景选择性活动涉及全局加工的假设。我们记录了参与者在观看人脸、物体和场景图像时的erp。图像以直立和倒置的方向呈现，跨越了广泛的类别维度和属性，防止了显著图像属性影响结果的可能性。重复之前的研究，发现P2是第一个场景选择成分，与面孔和物体相比，它对场景的反应幅度更高。反转对P2有明显的影响，其振幅对反转场景有所降低。在P1和N1这两个较早的视觉诱发成分上未观察到场景反转效应。相反，人脸反转对所有三个分量都有影响，而物体反转对任何三个分量都没有影响。目前的研究结果支持了P2索引场景选择性处理的概念，并表明全局场景信息是在P2时间窗口提取的。

Achievement motivation serves as a fundamental psychological construct that underlies and predicts a wide range of human adaptive behaviors, including goal setting and performance across academic and social domains. Although prior research has shown that self-control is associated with achievement motivation, it remains unclear which neural substrates underlie the association between self-control and achievement motivation. To address this issue, we employed resting-state functional connectivity (RSFC) and mediation analysis methods to investigate the neural basis of the relationship between self-control and achievement motivation in the discovery (N = 685) and replication sample (N = 210). In discovery sample, we found a significant positive correlation between self-control and achievement motivation. On the neural level, the FC between the left dorsolateral prefrontal cortex (dlPFC) and the right superior temporal gyrus (STG), right inferior temporal gyrus (ITG), and left middle temporal gyrus (MTG) were negatively correlated with self-control. Furthermore, the mediation analysis demonstrated that self-control fully mediated the relationship between the FC between left dlPFC and the right ITG and achievement motivation. Repeating analyses in the independent replication sample also supported the robustness of the results obtained in the discovery study. Together these findings indicate that the FC between left dlPFC and right ITG may represent a key neural pathway through which self-control influences achievement motivation, providing new insights into their association from a neural perspective.

成就动机是一种基本的心理结构，它预示着人类广泛的适应性行为，包括目标设定和在学术和社会领域的表现。虽然先前的研究表明自我控制与成就动机有关，但目前尚不清楚是哪种神经基质导致了自我控制与成就动机之间的联系。为了解决这一问题，我们采用静息状态功能连接（RSFC）和中介分析方法，在发现样本（N = 685）和复制样本（N = 210）中探讨自我控制与成就动机关系的神经基础。在发现样本中，我们发现自我控制与成就动机之间存在显著的正相关。在神经水平上，左侧背外侧前额叶皮层（dlPFC）与右侧颞上回（STG）、右侧颞下回（ITG）和左侧颞中回（MTG）之间的FC与自我控制呈负相关。此外，中介分析表明，自我控制完全中介了左侧dlPFC与右侧ITG之间的FC与成就动机之间的关系。在独立的复制样本中重复分析也支持了发现研究中获得的结果的稳健性。综上所述，这些研究结果表明，左侧dlPFC和右侧ITG之间的FC可能代表了自我控制影响成就动机的一条关键神经通路，从神经学的角度为它们之间的联系提供了新的见解。

Previous studies have investigated whether event-related potential (ERP) responses to negative and positive facial expressions are modulated by perceptual and working memory loads of face-irrelevant tasks, but results have been mixed. These studies typically employed traditional analysis methods that focus on a limited number of electrodes and timepoints, which increases the risk of statistical errors. Moreover, no studies have investigated these issues for emotionally ambiguous facial expressions. Therefore, the current study aimed to investigate whether working memory loads influence ERP effects of positive, negative and importantly, emotionally ambiguous (e.g., surprised) facial expressions by using robust Mass Univariate Analysis (MUA). To address these issues, thirty-three participants were presented with angry, happy, surprised or neutral faces. Participants were required to memorize a letter (low working memory loads) or 5 letters (high loads) before face presentations and to recognize them afterwards. ERP results showed that working memory loads and facial expressions independently affected ERP responses, with no significant interaction. Working memory loads influenced ERP responses starting after the P100 peak. Regarding the effect of facial expressions, surprised facial expressions generally weakened late positive potential (LPP) responses compared to other facial expressions, and happy facial expressions weakened the responses at early time ranges, while angry facial expressions enhanced LPP responses at distinct electrode sites depending on the comparison. These findings underscore the value of employing MUA for comprehensive ERP analysis in face processing research.

先前的研究已经调查了事件相关电位（ERP）对消极和积极面部表情的反应是否受到与面部无关任务的知觉和工作记忆负荷的调节，但结果好坏参半。这些研究通常采用传统的分析方法，集中在有限数量的电极和时间点上，这增加了统计误差的风险。此外，还没有研究调查过情绪模糊的面部表情的这些问题。因此，本研究旨在通过稳健的质量单变量分析（MUA）来研究工作记忆负荷是否会影响积极、消极和重要的情绪模糊（如惊讶）面部表情的ERP效应。为了解决这些问题，研究人员向33名参与者展示了愤怒、快乐、惊讶和中性的面孔。参与者被要求在面部展示之前记住一个字母（低工作记忆负荷）或5个字母（高工作记忆负荷），并在之后识别它们。结果显示，工作记忆负荷和面部表情对ERP反应有独立影响，但无显著交互作用。工作记忆负荷对ERP反应的影响始于P100峰值后。在面部表情的影响方面，惊讶的面部表情与其他面部表情相比，普遍减弱了晚期正电位（LPP）反应，快乐的面部表情减弱了早期时间范围的反应，而愤怒的面部表情则增强了不同电极部位的LPP反应。这些研究结果强调了在人脸加工研究中应用MUA进行综合ERP分析的价值。

Intrinsic neural timescales (INT) describe the storage time of neural information in local brain regions, representing the time window for information integration and segregation. Mental task-state electroencephalography (EEG) holds potential clinical value for patients; however, the test-retest reliability of INT remains an open issue. The present study aimed to explore the spatial characteristics of INT and investigate its test-retest reliability by analyzing the data from three mental tasks–subtraction, memory, and music–derived from an open-source EEG database. A classic spatial distribution hierarchy was demonstrated. Our results also revealed that INT had moderate-to-good test-retest reliability. The test-retest reliability of INT in the subtraction task was higher than that in memory and music tasks. Autocorrelation window (ACW)-0 exhibited superior test-retest reliability compared to ACW-50. In summary, our findings provide robust validation of the test-retest reliability of the mental task-state EEG INT from multiple perspectives, thereby facilitating its application in both basic research and clinical settings.

固有神经时间尺度（INT）描述了神经信息在大脑局部区域的存储时间，代表了信息整合和分离的时间窗口。心理任务状态脑电图（EEG）对患者具有潜在的临床价值；然而，INT的重测可靠性仍然是一个开放的问题。本研究通过分析来自开源脑电图数据库的减法、记忆和音乐三项心理任务数据，探讨脑电信号的空间特征及其重测信度。论证了典型的空间分布层次结构。我们的结果也显示INT具有中等到良好的重测信度。INT在减法任务中的重测信度高于记忆和音乐任务。与ACW-50相比，自相关窗口(ACW)-0表现出更高的重测信度。综上所述，我们的研究结果从多个角度对精神任务状态EEG INT的重测信度进行了稳健的验证，从而促进了其在基础研究和临床环境中的应用。

Objective: The variability in the operationalisation of cardiovascular recovery from psychological stress across studies is well-established in the field but little is done to address these issues. The aim of this study was to establish the temporal stability of multiple computations of cardiovascular recovery already documented in the literature. Secondly, the aim was to determine if temporal stability depended on how recovery was computed.

Methods: This study used previously collected data from the Pittsburgh Cold Study 3 (PCS3). One-hundred and eighty-nine participants (58.7 % male, two thirds Caucasian, age range; 18-55 years) completed two separate, identical, standardized stress-testing protocols (Mean = 48 days apart) and had their blood pressure and heart rate (HR) monitored throughout a baseline, stress task and recovery phase. Drawing on a multiverse framework, recovery was computed as 1) delta change score from baseline, 2) delta change score from task, 3) percent change baseline, 4) percent change task, 5) area under the curve with respect to ground (AUCg) and 6) area under the curve with respect to increase (AUCi).

Results: Delta change score from task, percent change task and AUCg demonstrated the strongest temporal stability for blood pressure and HR recovery between visits.

Conclusions: This study highlights the fragility of significant findings when multiple computations of cardiovascular recovery are considered within the multiverse framework, confirming that the status of results strongly depends on the computation of recovery that is chosen. We recommend employing multiverse analyses where feasible to confirm which computations are preferable. Where the multiverse is not feasible, we suggest using more sophisticated curve-fitting techniques like AUCg.

目的：在跨领域的研究中，从心理压力中恢复心血管功能的可变性是公认的，但很少有研究来解决这些问题。本研究的目的是建立文献中已有的心血管恢复多重计算的时间稳定性。其次，目的是确定时间稳定性是否取决于如何计算恢复。方法：本研究使用匹兹堡感冒研究3 （PCS3）先前收集的数据。189名参与者(58.7%男性，三分之二白种人，年龄范围；18-55岁)完成了两个独立的、相同的、标准化的压力测试方案（平均间隔48天），并在基线、压力任务和恢复阶段监测他们的血压和心率（HR）。根据多元宇宙框架，恢复的计算方法为：1)基线变化积分，2)任务变化积分，3)基线变化百分比，4)任务变化百分比，5)相对于地面的曲线下面积（AUCg）和6)相对于增加的曲线下面积（AUCi）。结果：任务变化积分、任务变化百分比和AUCg在两次访问之间的血压和HR恢复表现出最强的时间稳定性。结论：本研究强调了在多重宇宙框架内考虑心血管恢复的多重计算时，重要发现的脆弱性，证实了结果的地位在很大程度上取决于所选择的恢复计算。我们建议在可行的情况下使用多元宇宙分析来确定哪种计算更可取。在多元宇宙不可行的地方，我们建议使用更复杂的曲线拟合技术，比如AUCg。

Social touch, such as hugging and hand-holding, may aid in the maintenance of feelings of social connection. Research on gentle stroking has demonstrated its social-affective effects. However, other elements of touch that might contribute to feelings of social connection are poorly understood. The current research seeks to determine the effect of warmth and pressure, given their involvement in social touch, on feelings of social connection with close others. In a 2 × 2 within-subjects experiment, 75 participants (M age = 19.89, 77.30 % women), were exposed to repeated trials of warm or neutral temperature packs, combined with deep or light pressure from weighted blankets, while they viewed images of close others. Feelings of social connection towards the pictured individuals were collected after each trial. After adjusting for age, there was an interaction such that warm deep pressure increased feelings of social connection compared to warm light pressure and neutral deep pressure. Individual differences in interoceptive sensibility also moderated effects, with greater clarity in interoceptive signals predicting higher feelings of social connection during warm deep pressure (vs. warm light pressure). The combination of warmth and pressure, therefore, increases feelings of social connection toward close others compared to warmth or pressure alone. Results are the first to demonstrate a role of pressure in feelings of social connection and are consistent with perspectives emphasizing afferent feedback from the body in socioemotional experience.

社交接触，如拥抱和牵手，可能有助于维持社会联系的感觉。对温柔抚摸的研究已经证明了它的社会情感效应。然而，人们对其他可能对社会联系感有贡献的触摸元素知之甚少。目前的研究试图确定温暖和压力对与亲密他人的社会联系感觉的影响，因为它们与社会接触有关。在一项2 × 2的受试者实验中，75名参与者（M年龄= 19.89,77.30 %为女性）暴露于温暖或中性温度包的重复试验中，并结合加重毯子的深压或轻压，同时他们观看亲密他人的图像。每次试验结束后，研究人员都会收集照片中被试者的社会联系感受。在调整了年龄之后，与温暖的轻度压力和中性的深度压力相比，有一种相互作用，即温暖的深度压力增加了社会联系感。内感受敏感性的个体差异也调节了影响，内感受信号的清晰度更高，预示着在温暖的深压力下（与温暖的光压力相比）有更高的社会联系感。因此，与单独的温暖或压力相比，温暖和压力的结合增加了对亲密他人的社会联系感。研究结果首次证明了压力在社会联系感受中的作用，并与强调身体在社会情感体验中的传入反馈的观点一致。

Oxytocin administration is a valuable approach for experimentally increasing central oxytocin levels to investigate its impact on brain function and behavior. Despite considerable research interest, results have shown considerable variability across studies. Several meta-analyses have been conducted to help address this inconsistency. However, conducting a meta-analysis requires researchers to make numerous decisions, such as defining inclusion criteria and analytical techniques. In response to this challenge, a ‘multiverse’ approach can be used to simultaneously explore a range of different potential and realistic scenarios by systematically varying these analytical decisions. In this study, we performed a multiverse meta-analysis to investigate how researcher decisions can influence outcomes in meta-analyses of oxytocin administration studies. We systematically varied inclusion criteria, data synthesis models, and methods for correcting publication bias across 530 effect sizes derived from 185 studies, conducting 256 distinct meta-analyses. Our results demonstrate that summary effect estimates can vary considerably depending on meta-analytic decisions (from d = −0.16 to d = 1.45). Notably, meta-analyses with neurotypical populations tended to yield larger effect sizes than non-neurotypical populations, and multiple administrations studies tended to yield larger effect sizes than single administration studies. Furthermore, summary effect estimates can substantially vary according to the applied publication bias correction method. Our findings also demonstrated that the current evidence mostly supports the presence of the effect of oxytocin across domains, regardless of meta-analytic choices, as over 90% of the observed meta-analyses exceeded the range of bootstrapped meta-analyses assuming a null effect. These results warrant future research on how different contexts may impact the robustness of the effects of oxytocin, while underscoring the value of meta-analysis pre-registration to facilitate the transparent evaluation of meta-analyst decision-making.

通过实验增加中枢催产素水平来研究其对脑功能和行为的影响是一种有价值的方法。尽管有相当大的研究兴趣，但研究结果显示出相当大的差异。已经进行了几项元分析来帮助解决这种不一致。然而，进行荟萃分析需要研究人员做出许多决定，例如定义纳入标准和分析技术。为了应对这一挑战，“多元宇宙”方法可以通过系统地改变这些分析决策来同时探索一系列不同的潜在和现实场景。在这项研究中，我们进行了一项多元元分析，以调查研究者的决定如何影响催产素给药研究的元分析结果。我们系统地改变了纳入标准、数据综合模型和纠正发表偏倚的方法，这些方法来自185项研究的530个效应量，进行了256项不同的荟萃分析。我们的研究结果表明，根据元分析的决定，总效应估计可能会有很大的变化（d = -0.16至1.45）。值得注意的是，神经典型人群的荟萃分析往往比非神经典型人群产生更大的效应量，而多次给药研究比单次给药研究产生更大的效应量。此外，根据应用的发表偏倚校正方法，总效应估计可能会有很大差异。我们的研究结果还表明，目前的证据主要支持催产素跨领域影响的存在，而不管meta分析的选择是什么，因为超过90%的观察到的meta分析超出了假设无效效应的自举meta分析的范围。这些结果为未来关于不同背景如何影响催产素效应的稳健性的研究提供了依据，同时强调了元分析预登记的价值，以促进元分析决策的透明评估。

Executive cognitive functions are essential for human life, and their age- or disease-related decline significantly impacts quality of life. Non-invasive brain stimulation (NIBS) targeting the multiple-demand or fronto-parietal network (FPN) has emerged as a promising intervention for enhancing various executive cognitive functions. However, variations in cognitive tasks and stimulation protocols across studies led to mixed results, rendering findings and conclusions incomparable. In this study, we synchronized oscillations over two main areas of the frontoparietal cognitive network, right dorsolateral prefrontal cortex (rDLPFC) and right posterior parietal cortex (rPPC), using high-definition (HD) dual-channel in-phase transcranial alternating current stimulation (tACS) at various stimulation frequencies (6 Hz, 40 Hz, sham). Participants completed a spatial attention task, a 3-back memory task, and a flanker cognitive control task while receiving tACS stimulation. Results revealed that gamma-band (40 Hz) stimulation improved response speed in the spatial attention task among younger participants but impaired response speed in the flanker task. Contrary to our initial expectations, theta-band stimulation did not affect cognition significantly. These findings highlight the specificity of cognitive enhancement through tACS and suggest that optimal stimulation targets may vary across cognitive domains, providing clinical implications for using tACS in treating cognitive deficits.

执行认知功能对人类生活至关重要，其年龄或疾病相关的下降会显著影响生活质量。针对多需求或额顶叶网络（FPN）的非侵入性脑刺激（NIBS）已成为一种有前途的干预措施，可增强各种执行认知功能。然而，不同研究的认知任务和刺激方案的差异导致了不同的结果，使得研究结果和结论无法比较。在这项研究中，我们在不同的刺激频率（6 Hz, 40 Hz，假）下，使用高清（HD）双通道同相经颅交流电刺激（tACS），同步了额顶叶认知网络的两个主要区域，右侧背外侧前额叶皮层（rDLPFC）和右侧后顶叶皮层（rPPC）的振荡。参与者在接受tACS刺激的同时完成了空间注意任务、3-back记忆任务和侧卫认知控制任务。结果表明，40 Hz的伽马波段刺激提高了年轻被试空间注意任务的反应速度，但降低了侧翼任务的反应速度。与我们最初的预期相反，θ波段刺激并没有显著影响认知。这些发现强调了通过tACS增强认知的特异性，并提示最佳刺激目标可能在不同的认知领域有所不同，为使用tACS治疗认知缺陷提供了临床意义。

The hypothalamic-pituitary-adrenal (HPA) axis and its end-product cortisol play an important role in adaptation to stressful situations. Previous studies have suggested brain regions in the limbic area (e.g., basolateral amygdala-BLA, centromedial amygdala-CMA, hippocampus) regulate cortisol stress response (i.e., initial cortisol stress reactivity and a late recovery). However, whether these limbic areas regulate cortisol stress reactivity and recovery differently remains elusive. Using the Seed-to-Voxel gPPI analysis, we explored the functional connectivity (FC) between the limbic area and other brain regions during stress induction and their association with cortisol stress reactivity. Similarly, we explored their FC during post-stress rest and their association with cortisol stress recovery. We found that both BLA and CMA connectivity related to cortisol stress reactivity during stress induction, with similarity in FC with precuneus and differences in FC with angular gyrus, precentral gyrus, and PFC; the BLA rather than CMA connectivity with PFC linked to cortisol stress recovery during post-stress rest. Furthermore, the hippocampal-PFC connectivity only affected cortisol stress recovery during post-stress rest, and in a different direction from the effect of BLA-PFC connectivity. Our findings provide important insight into the neurobiological etiology underlying how limbic FC regulates HPA axis stress reactivity and recovery. This highlights the importance of targeting acute stress reactivity and recovery separately in interventions for stress-related disorders.

下丘脑-垂体-肾上腺（HPA）轴及其终产物皮质醇在适应压力情境中起着重要作用。先前的研究表明，大脑边缘区域（如基底外侧杏仁核- bla、中央内侧杏仁核- cma、海马）调节皮质醇应激反应（即初始皮质醇应激反应和后期恢复）。然而，这些边缘区域是否以不同的方式调节皮质醇应激反应和恢复仍然难以捉摸。利用种子到体素的gPPI分析，我们探索了应激诱导过程中边缘区和其他大脑区域之间的功能连接（FC）及其与皮质醇应激反应的关系。同样，我们探索了他们在应激后休息期间的FC及其与皮质醇应激恢复的关系。我们发现，应激诱导过程中，BLA和CMA的连通性与皮质醇应激反应有关，FC与楔前叶相似，而FC与角回、中央前回和PFC存在差异；在应激后休息期间，与皮质醇应激恢复有关的是BLA而不是CMA与PFC的连接。此外，海马- pfc连接仅影响应激后休息期间皮质醇应激的恢复，并且与BLA-PFC连接的影响方向不同。我们的研究结果为边缘FC如何调节HPA轴应激反应和恢复的神经生物学病因提供了重要的见解。这突出了在压力相关疾病的干预中分别针对急性应激反应和恢复的重要性。

Perspective on self-regulatory capacity and the vagus nerve: Have we wandered too far? 自我调节能力和迷走神经的观点：我们走得太远了吗？

The concept of self regulation has been of interest to psychologists for decades, and physiological mechanisms that underpin self regulatory ability are of clinical interest. Two mechanistic theories have been proposed: the polyvagal theory (PVT) and neurovisceral integration model (NVIM), each assuming vagus nerve activity to be a readout of self regulatory capacity. This paper critically examines the extant research that identifies purported associations between self-regulation and cardiac activity, confusion around constructs, misleading claims about the relationship between HF-HRV/RSA and vagal activity, methodological problems, errors in neuroanatomy, contradictory findings, and lack of consideration of social context and resource availability in defining effective self-regulation behaviors.

几十年来，心理学家一直对自我调节的概念感兴趣，而支撑自我调节能力的生理机制也引起了临床的兴趣。目前已经提出了两种机制理论：多迷走神经理论（PVT）和神经内脏整合模型（NVIM），它们都假设迷走神经活动是自我调节能力的一种表现。本文批判性地审查了现有的研究，这些研究确定了自我调节与心脏活动之间的关联，围绕结构的混淆，关于HF-HRV/RSA与迷走神经活动之间关系的误导性主张，方法问题，神经解剖学错误，矛盾的发现，以及在定义有效的自我调节行为时缺乏对社会背景和资源可用性的考虑。
