Cross-situational word learning describes the process by which learners acquire new words by tracking statistical regularities obtained from ambiguous word-referent encoding encounters over time. This study measured event-related potentials and behavioural responses to assess the acquisition of written word meanings through cross-situational word learning, in which novel orthographic forms served as written names for familiar objects. During the learning phase, participants disambiguated mappings between novel written words (e.g., ‘ket’) and familiar objects (e.g., sword). After learning, participants performed a semantic relatedness judgement task, pairing newly learned words with familiar written words from either a related (e.g., dagger) or unrelated (e.g., harp) semantic category. To provide a control measure, the semantic judgement task also included a condition comprising semantically related and unrelated familiar word pairs. Analyses revealed an N400 effect for semantic judgements of word meaning relatedness, both for the novel–familiar and familiar–familiar word pair conditions. These findings suggest that novel written word meanings can be rapidly acquired through cross-situational learning, with neurophysiological responses that resemble those for familiar words, albeit showing a more left-hemisphere distribution for novel words and a more right-hemisphere distribution for familiar words.
跨情景词汇学习描述了学习者通过跟踪从模糊词指编码中获得的统计规律来学习新单词的过程。本研究测量了事件相关电位和行为反应,以评估通过跨情境单词学习获得的书面单词含义。在跨情境单词学习中,新奇的正字法形式作为熟悉物体的书面名称。在学习阶段,参与者消除了新的书面单词(如“ket”)和熟悉的物体(如剑)之间的歧义映射。学习后,参与者进行语义相关性判断任务,将新学习的单词与熟悉的书面单词配对,这些单词要么是相关的(如匕首),要么是不相关的(如竖琴)。为了提供一种控制措施,语义判断任务还包括一个由语义相关和不相关的熟悉词对组成的条件。分析发现,在新熟悉词对和熟悉熟悉词对条件下,词义相关性的语义判断存在N400效应。这些发现表明,通过跨情境学习,可以快速获得新的书面单词的含义,其神经生理反应与熟悉的单词相似,尽管新单词的左半球分布更大,熟悉的单词的右半球分布更大。

Single case studies have long been used to provide insights into the mechanisms underlying normal cognition, including in the domains of memory, language and visuoperceptual function, and standardized testing has been a steadfast companion in such investigations. Experimental approaches designed to address specific hypotheses have also been conducted and analytic methods have been developed for the comparison of single subject data to a control group. However, a seismic shift has occurred in the last decade or two in which neuroimaging, primarily magnetic resonance imaging, has been added to the experimental toolbox. The question addressed in this article is whether, with these newer methodologies offering novel and previously unattainable evidence, single case studies have become obsolete. Here, in a single patient with integrative visual agnosia, tested repeatedly over three decades, behavioral, neuroimaging and joint behavioral-neuroimaging studies are described and their yield evaluated. Behavioral investigations have served to characterize the perceptual deficit well, and structural and functional neuroimaging data have furthered our understanding of the distributed circuit engaged in object recognition. However, imaging studies executed in concert with a behavioral task have offered more direct causal evidence, providing a more complete understanding of brain-behavior correspondences that goes beyond the sum of the parts. The conclusion reached is that the contribution of causal evidence from single cases remains a powerful methodology in advancing our knowledge of the neural basis of cognition.
长期以来,单一案例研究一直被用来提供对正常认知机制的见解,包括在记忆、语言和视觉功能领域,标准化测试一直是此类调查的坚定伴侣。还进行了旨在解决特定假设的实验方法,并开发了用于将单个受试者数据与对照组进行比较的分析方法。然而,在过去的十年或二十年里,神经成像,主要是磁共振成像,已经被添加到实验工具箱中,发生了翻天覆地的变化。本文讨论的问题是,随着这些新方法提供新颖且以前无法获得的证据,单一案例研究是否已经过时。在此,对一名综合性视觉失认症患者进行了30多年的反复测试,描述了行为、神经成像和联合行为-神经成像研究,并对其结果进行了评估。行为研究已经很好地描述了感知缺陷,结构和功能神经成像数据进一步加深了我们对参与物体识别的分布式电路的理解。然而,与行为任务一起执行的成像研究提供了更直接的因果证据,提供了对大脑-行为对应关系的更完整的理解,而不仅仅是部分的总和。得出的结论是,来自单个案例的因果证据的贡献仍然是一个强大的方法,在推进我们的认知的神经基础的知识。

Although numerous studies have primarily associated creativity with spontaneous thought and its corresponding neural networks, effective creativity entails much more than uninhibited ideation. It requires the capacity to filter out irrelevant information, maintain optimal attentional tuning, and strategically regulate and refine innovative outputs. We argue that a robust and adaptive executive control network (ECN), operating in concert with attentional networks, is essential for creativity. Accordingly, we hypothesized that high-creative individuals would exhibit enhanced top-down modulation from both the ECN and attention networks onto other brain networks. To test this hypothesis, we employed resting-state fMRI and Dependency Network Analysis (DEPNA) to examine differences in hierarchical influence patterns across multiple brain regions and networks between individuals with high and low creative abilities. Our analyses revealed that high-creative individuals, relative to their low-creative counterpart, exhibited increased influence of specific brain regions on inter-regional functional connectivity across multiple brain regions. These regions demonstrating augmented influence were predominantly localized within the ECN and ventral attention network (VAN), specifically the bilateral inferior frontal gyrus (IFG), bilateral inferior frontal sulcus (IFS), and right middle frontal gyrus (MFG). Moreover, high-creative individuals displayed significantly greater influence of the ECN and the dorsal attention network (DAN) on other large-scale brain networks. These findings suggest top-down cognitive and attentional control may be crucial in facilitating creativity.
尽管许多研究主要将创造力与自发思维及其相应的神经网络联系起来,但有效的创造力需要的不仅仅是不受约束的思维。它需要过滤掉不相关信息的能力,保持最佳的注意力调整,战略性地调节和完善创新的产出。我们认为,一个强大的、自适应的执行控制网络(ECN),与注意力网络协同工作,对创造力至关重要。因此,我们假设高创造力的个体会表现出增强的从外神经网络和注意力网络到其他大脑网络的自上而下的调节。为了验证这一假设,我们采用静息状态功能磁共振成像(fMRI)和依赖网络分析(DEPNA)来检查高创造力和低创造力个体在多个大脑区域和网络中的层次影响模式差异。我们的分析显示,与低创造力个体相比,高创造力个体的特定大脑区域对跨多个大脑区域间功能连接的影响更大。这些表现出增强影响的区域主要位于ECN和腹侧注意网络(VAN)内,特别是双侧额下回(IFG)、双侧额下沟(IFS)和右侧额中回(MFG)。此外,高创造力个体的ECN和背侧注意网络(DAN)对其他大尺度脑网络的影响显著更大。这些发现表明,自上而下的认知和注意力控制可能对促进创造力至关重要。

In episodic memory, emotional items often can be remembered better than neutral ones, whereas this emotional salience effect is not observed in source memory (neutral extrinsic or contextual details). However, it remains unclear whether this dissociation is evident in subjective metamemory judgments—specifically judgments of learning (JOLs) and judgments of sources (JOSs). To reveal the effects of emotions on these two types of metamemory judgments and their neural mechanisms, we used different emotion (negative, positive, and neutral) pictures with neutral contextual details. Results revealed that both JOLs and JOSs showed emotional salience effects, supporting the universal role of emotion as a metamemory cue. Event-related potential (ERP) results revealed shared neural mechanisms underlying both judgment types: early automatic processing (evidenced by enhanced P200 and reduced N400) and late controlled processing (late positive components). Crucially, the neural activity within this shared subjective pathway was functionally dissociated from the encoding processes diagnostic of subsequent memory success. Both judgment types exhibited right-hemisphere lateralization for high versus low metamemory ratings. Nevertheless, JOLs elicited more widespread and sustained neural activity patterns than JOSs in both emotion-neutral contrasts and high-low rating differences. These findings support the Dual-basis theory of metamemory (experience-belief interaction) and suggest that item and source metamemory judgments rely on partially distinct neural mechanisms. This provides neurophysiological insights for optimizing metacognitive training strategies.
在情景记忆中,情绪项目通常比中性项目更容易被记住,而这种情绪显著效应在源记忆(中性的外在细节或情境细节)中没有观察到。然而,目前尚不清楚这种分离在主观元记忆判断中是否明显,特别是学习判断(JOLs)和来源判断(JOSs)。为了揭示情绪对这两种元记忆判断的影响及其神经机制,我们使用了具有中性背景细节的不同情绪图片(消极、积极和中性)。结果显示,jol和jos均表现出情绪显著效应,证实了情绪作为元记忆线索的普遍作用。事件相关电位(ERP)结果揭示了两种判断类型的共同神经机制:早期自动加工(以P200增强和N400降低为证据)和晚期控制加工(晚期积极成分)。至关重要的是,这一共同主观路径中的神经活动在功能上与诊断后续记忆成功的编码过程分离。两种判断类型在高记忆评分和低记忆评分时都表现出右半球偏侧化。然而,在情绪中性对比和高低评分差异中,JOLs比jos引发了更广泛和持续的神经活动模式。这些发现支持了元记忆的双重基础理论(经验-信念相互作用),并表明项目元记忆判断和源元记忆判断依赖于部分不同的神经机制。这为优化元认知训练策略提供了神经生理学的见解。

Psychosocial stress induces stress responses at physiological and cognitive levels which disrupt subsequent sleep. A recent study from our group has shown that stress-induced changes are dynamic: stress before sleep led to prolonged sleep latency and changes in the early sleep period, while anticipated post-sleep stress resulted in changes in the late sleep period. A possible explanation is that anticipated stress is spontaneously reactivated during sleep in a dynamic fashion. As reactivations might be linked to dream content, we investigated the influence of anticipated stress vs. pre-sleep stress on dream content in early and late sleep periods. One group of participants performed either a stress or a relaxation task before sleep (pre-sleep group); while another group was informed before sleep that the stress or relaxation task will occur in the morning (post-sleep group). During sleep, they were regularly woken up in the early and late sleep periods and asked about their cognitive activity, while polysomnographic data was recorded. Fifty-five subjects participated and a total of 668 dreams was collected. While there was no difference in the incorporation of threat- and stress-related elements in the dreams, we did find a temporal difference in their emotionality. The threat intensity was influenced in a dynamic manner, with higher impact on early dreams when stress occurred before sleep and higher threat intensity in late dreams when stress was anticipated after sleep. Our results speak for a reactivation of mental activity in temporal proximity to the stressor for some parameters, mainly with impacts on the dream emotionality and length.
社会心理压力引起生理和认知水平的应激反应,从而扰乱随后的睡眠。我们小组最近的一项研究表明,压力引起的变化是动态的:睡前的压力导致睡眠潜伏期延长和早期睡眠阶段的变化,而预期的睡眠后压力导致晚期睡眠阶段的变化。一种可能的解释是,预期的压力在睡眠中以一种动态的方式自发地重新激活。由于再激活可能与梦境内容有关,我们研究了预期压力与睡眠前压力对睡眠早期和晚期梦境内容的影响。一组参与者在睡觉前执行压力或放松任务(睡前组);而另一组在睡觉前被告知压力或放松任务将在早上进行(睡眠后组)。在睡眠期间,研究人员定期在睡眠的早期和晚期叫醒他们,询问他们的认知活动,同时记录多导睡眠图数据。55名受试者参与了这项研究,总共收集了668个梦。虽然在梦境中与威胁和压力相关的因素的结合方面没有差异,但我们确实发现了他们情绪上的时间差异。威胁强度的影响是动态的,当压力发生在睡眠前时,对早期梦的影响更大,而当压力发生在睡眠后时,对晚期梦的威胁强度更高。我们的研究结果表明,在某些参数下,与压力源在时间上的接近会重新激活心理活动,主要影响梦境的情绪和长度。

Human voices carry rich information, including identity and linguistic information. The question of whether voice identity information affects linguistic information processing has long been debated among different scientific schools. Among the various factors that contribute to this debate, the effect of voice familiarity on linguistic information has been a critical pathway. The present study differentiated the physically from psychologically familiar voices and investigated how these two types of familiar voices affect spoken word processing. We conducted two experiments with event-related potentials (ERPs) and time-frequency analyses. Experiment 1 employed a lexical decision task with the emotional words spoken by unfamiliar, physically, and psychologically familiar speakers. The N100 and P200 results showed that participants could distinguish between physically and psychologically familiar voices and the voice familiarity would affect linguistic information processing at an early time window. The results of the Alpha frequency band indicated that linguistic information, in turn, affects the processing of different speakers in an later time window. Experiment 2 utilized a valence rating task that required more depth of semantic processing. The N100 and P200 results indicated similar findings to Experiment 1. The N400 results suggested that voice familiarity also affects the linguistic information processing at the semantic processing stage. Moreover, the Theta frequency band results suggested that linguistic information affects the processing of different speakers in an middle-later time window. Token together, these findings revealed that voice familiarity affects spoken word processing differently with regard to the time course of processing and task demands. We proposed a dynamic model of spoken word processing that incorporates voice familiarity, enhancing our understanding of the role of voice identity in linguistic information processing.
人的声音承载着丰富的信息,包括身份信息和语言信息。语音识别信息是否影响语言信息处理的问题在不同的科学流派之间一直存在争议。在导致这一争论的各种因素中,语音熟悉度对语言信息的影响一直是一个重要的途径。本研究将生理上熟悉的声音与心理上熟悉的声音区分开来,探讨了这两种熟悉的声音对口语文字处理的影响。我们用事件相关电位(ERPs)和时频分析进行了两个实验。实验1采用词汇决策任务,对不熟悉的、身体上熟悉的和心理上熟悉的说话者所说的情感词汇进行分析。N100和P200结果表明,被试能够区分生理上和心理上熟悉的声音,语音熟悉程度会在较早的时间窗口影响语言信息加工。Alpha频带的结果表明,语言信息反过来影响不同说话者在以后的时间窗口中的加工。实验2采用对语义处理深度要求更高的效价评定任务。N100和P200的结果与实验1相似。N400结果表明,语音熟悉度也会影响语义加工阶段的语言信息加工。此外,Theta频带结果表明,语言信息在中后期时间窗内影响不同说话者的加工。综上所述,这些研究结果表明,语音熟悉度对口语单词处理的影响在处理的时间过程和任务要求方面是不同的。我们提出了一个包含语音熟悉度的口语单词处理动态模型,增强了我们对语音身份在语言信息处理中的作用的理解。

Cognitive maps, traditionally considered metrically accurate mental representations of space, have been central to navigation research. However, recent studies suggest human navigation often deviates from the predictions of cognitive maps. Instead, cognitive graphs - spatial representations based on landmarks (nodes) connected by routes (edges) with relative distances, angles and limited metric information - may more accurately describe mental spatial representation. Unlike cognitive maps, cognitive graphs emphasize structural relationships over precise details. We designed a two-alternative forced-choice navigational task where participants explored and navigated virtual environments with three ways to a target: left, middle, and right. Critically, the left and right routes were always identical in length but varied in structural features like the number of turns, length of the first path of the route, or the size of unpaved areas. After exploring, the middle route was blocked and participants chose the left or right route to navigate to the target. Across two experiments, participants completed the task using an immersive walking virtual reality interface or a desktop computer to view top-down images. Participants in both experiments preferred routes with fewer turns and larger inner and outer areas despite being metrically identical, but showed no preference for routes with a shorter initial path. These findings suggest that participants did not rely on metrically precise cognitive maps when deciding which route to take to a navigational goal. We interpret this as evidence for the use of topological or labeled graph representations and discuss heuristics that are compatible with or may drive reliance on cognitive graphs over cognitive maps. These findings build on prior evidence for cognitive graphs in physically impossible environments (e.g., wormholes) by showing a bias in the absence of route length differences.
认知地图,传统上被认为是空间精确的心理表征,一直是导航研究的核心。然而,最近的研究表明,人类导航经常偏离认知地图的预测。相反,认知图——基于相对距离、角度和有限度量信息的路线(边缘)连接的地标(节点)的空间表征——可能更准确地描述心理空间表征。与认知图不同,认知图强调结构关系而不是精确的细节。我们设计了一个两种选择的强制选择导航任务,参与者在虚拟环境中探索和导航,有三种方式到达目标:左、中、右。关键是,左右路线的长度总是相同的,但在结构特征上却有所不同,比如转弯的数量、路线第一条路径的长度或未铺设区域的大小。在探索后,中间的路线被封锁,参与者选择左边或右边的路线来导航到目标。在两个实验中,参与者使用沉浸式行走虚拟现实界面或台式电脑来完成任务,以查看自上而下的图像。两个实验的参与者都更喜欢转弯少、内外面积大的路线,尽管它们在度量上是相同的,但对起始路径较短的路线没有表现出偏好。这些发现表明,参与者在决定走哪条路线到达导航目标时,并不依赖于精确的认知地图。我们将此解释为使用拓扑或标记图表示的证据,并讨论与认知图兼容或可能驱动对认知图而不是认知图的依赖的启发式。这些发现建立在物理上不可能的环境(例如,虫洞)的认知图的先前证据的基础上,通过显示在没有路径长度差异的情况下的偏差。

The human relationship with mortality has been widely studied in psychology, with extensive studies suggesting that death-related stimuli impact behavior even without reflective awareness. In recent decades, neuroimaging studies have yielded various contenders for brain regions underlying the online processing of death-related stimuli. To the best of our knowledge, we present here the first systematic review of these findings. We conducted a comprehensive search for studies where participants were presented with death-related and death-unrelated but negatively valenced (unpleasant) stimuli while undergoing functional brain imaging. We found seven functional magnetic resonance imaging studies with a total of 204 participants. Five of six within-group studies found that unpleasant stimuli consistently elicited increased insular activity, but only when it was unrelated to mortality. This novel finding—that insular deactivation alone marks the processing of death-related stimuli—suggests a critical difference between the neural processing of death-related and non-death related, unpleasant stimuli. We argue that preexisting explanatory frameworks fail to unite our results with findings on threat processing mechanisms in the insula or lack evolutionary plausibility. We present an alternative explanation: death might be unique in that it evades the insula's typical threat-assessment mechanisms.
Further research is needed to determine whether this neural signature is robust and what its function and consequences may be. A better understanding of how individuals process death-related information promises deeper insight into the human relationship with mortality, with significant implications for individuals and society, not least for mental health interventions and end-of-life care.
人类与死亡的关系在心理学上得到了广泛的研究,大量的研究表明,与死亡相关的刺激即使在没有反思意识的情况下也会影响行为。近几十年来,神经成像研究已经为在线处理死亡相关刺激的大脑区域提供了各种竞争者。据我们所知,我们在此首次对这些发现进行系统回顾。我们进行了一项全面的研究,在这些研究中,参与者在接受功能性脑成像的同时接受与死亡相关和与死亡无关但负效(不愉快)的刺激。我们找到了7个功能性磁共振成像研究,共204名参与者。六项组内研究中有五项发现,不愉快的刺激始终会引起岛岛活动的增加,但只有在与死亡率无关的情况下才会如此。这一新颖的发现——仅岛叶失活就标志着对死亡相关刺激的处理——表明了神经处理与死亡相关和非死亡相关的不愉快刺激之间的关键差异。我们认为,先前存在的解释框架未能将我们的结果与脑岛威胁处理机制的发现结合起来,或者缺乏进化的合理性。我们提出了另一种解释:死亡可能是独特的,因为它避开了脑岛典型的威胁评估机制。需要进一步的研究来确定这种神经特征是否稳健,以及它的功能和后果可能是什么。更好地了解个人如何处理与死亡有关的信息,有望更深入地了解人类与死亡的关系,这对个人和社会,尤其是对心理健康干预和临终关怀具有重大意义。

Creative thinking is a vital skill for engineers. Prior work suggests that social dynamics—such as critical feedback from a high-authority figure—can influence the ideation process. Yet little is known about the neurocognitive mechanisms through which feedback shapes creative thinking. In this study, engineering students completed a creative ideation task while EEG was recorded. Midway through the experiment, a professor gave the participant either supportive or unsupportive critical feedback on their performance. Supportive feedback was expected to positively influence creativity compared to unsupportive feedback: participants in the supportive feedback condition were predicted to show greater idea originality and fluency after receiving feedback, as well as a greater EEG power increase in the alpha frequency band (8–12 Hz) that is robustly associated with creativity. We found that after receiving feedback—whether supportive or unsupportive—participants produced fewer but more highly original responses and showed increased alpha power. These results indicate that feedback can cause engineers to generate fewer but more original ideas by driving alpha-band activity in the brain. In further analyses, we found decreased beta-band activity before feedback only in the unsupportive condition, possibly reflecting increased cognitive stress and internally directed attention required to adjust performance in the post-feedback phase.
创造性思维是工程师的一项重要技能。先前的研究表明,社会动力——比如来自权威人物的批评反馈——可以影响思维过程。然而,我们对反馈如何塑造创造性思维的神经认知机制知之甚少。在本研究中,工科学生完成了一项创造性思维任务,同时记录了脑电图。在实验进行到一半时,一位教授对参与者的表现给予支持或不支持的批评反馈。与非支持性反馈相比,支持性反馈预计会对创造力产生积极影响:支持性反馈条件下的参与者在接受反馈后,预计会表现出更大的创意和流畅性,并且与创造力密切相关的α频段(8-12 Hz)的脑电图功率也会增加。我们发现,在接受反馈后——无论是支持的还是不支持的——参与者产生的反应更少,但更具有原创性,并显示出更高的阿尔法能量。这些结果表明,反馈可以通过驱动大脑中的α波段活动,使工程师产生更少但更多的原创想法。在进一步的分析中,我们发现只有在不支持的情况下,反馈前的β -波段活动才会下降,这可能反映了在反馈后阶段调整表现所需的认知压力和内部定向注意力的增加。

Spatial maps in the mind: An integrative review of mobility’s role in wayfinding 心灵中的空间地图:在寻路过程中移动性作用的综合综述

Spatial navigation is a complex behavior that depends on cognitive wayfinding ability and mobility function, which are vulnerable to decline in aging and neurodegenerative disease. Extant research has largely focused on the cognitive basis of navigation, including exploration of the environment and the subsequent creation of a “cognitive map”. Current theoretical accounts of human spatial navigation ability typically feature mobility function implicit to enacted locomotion, and do not consider the potential for mobility function to modify cognitive wayfinding processes that support navigation. We provide an integrative review of growing evidence that suggests a role of mobility to modify wayfinding that goes beyond locomotion alone. We provide a hypothesized model that includes components of mobility contributing to the development of a cognitive map through exploration and prospective selection of detail based on egocentric cue preference and perceived mobility constraint. In addition, motor planning may inform goal selection, route planning, monitoring and adaptation. We conclude with recommendations on intentional study design with assessments that can be completed in most laboratory settings that have potential for clinical translation with the goal to understand vulnerabilities of real-world navigation and its profound impact on day-to-day living in aging and clinical populations.
空间导航是一种依赖于认知寻路能力和移动功能的复杂行为,在衰老和神经退行性疾病中容易下降。现存的研究主要集中在导航的认知基础上,包括对环境的探索和随后的“认知地图”的创建。目前关于人类空间导航能力的理论描述通常以隐含的移动功能为特征,而没有考虑移动功能改变支持导航的认知寻路过程的潜力。我们对越来越多的证据进行了综合回顾,这些证据表明移动性在改变寻路方面的作用不仅仅是运动。我们提供了一个假设模型,其中包括通过探索和基于自我中心提示偏好和感知移动约束的前瞻性细节选择来促进认知地图发展的移动性成分。此外,运动规划可以为目标选择、路线规划、监测和适应提供信息。最后,我们提出了关于有意研究设计的建议和评估,这些评估可以在大多数实验室环境中完成,具有临床转化的潜力,目的是了解现实世界导航的脆弱性及其对老年人和临床人群日常生活的深远影响。
