The present study investigates attentional biases (ABs) in gamblers and non-gamblers, focusing on both gambling-related and food-related stimuli to examine the relationship between these biases and the Incentive Sensitization (IS) and Reward Deficiency Syndrome (RDS) models of addiction. Using an eye-tracking methodology, we assess how ABs differ across three conditions involving two types of images: Food vs. Gambling, Food vs. Neutral, and Gambling vs. Neutral. Gamblers showed a significant AB toward gambling-related stimuli compared to neutral cues, supporting the IS model. However, when gambling and food images were compared, no significant difference in AB was found, partially disconfirming the hypothesis that gamblers exhibit a stronger bias toward gambling stimuli. In contrast, non-gamblers demonstrated a clear preference for food-related images, as predicted by the IS model. Additionally, group differences revealed that gamblers allocated more attention to gambling-related cues than non-gamblers. However, food images elicited similar levels of attention from both gamblers and non-gamblers when compared to neutral images, rather than gambling-related images. These findings highlight the role of ABs in the development and maintenance of gambling behaviour, supporting the IS model but not the RDS model. The study also explores the association between AB and severity of gambling and other relevant psychological factors in gambling disorder, providing new insights into the cognitive mechanisms underlying gambling addiction. These results suggest that ABs could be targeted in interventions aimed at modifying attention patterns and reducing gambling-related cravings.

本研究调查了赌徒和非赌徒的注意偏差（ABs），重点研究了赌博相关和食物相关的刺激，以检验这些偏差与成瘾的激励敏感化（IS）和奖励缺乏综合征（RDS）模型之间的关系。使用眼动追踪方法，我们评估了ab在涉及两种类型图像的三种情况下的差异：食物vs.赌博，食物vs.中性，赌博vs.中性。与中性线索相比，赌徒对赌博相关刺激表现出显著的AB，支持IS模型。然而，当赌博和食物图像进行比较时，没有发现AB的显著差异，部分地否定了赌徒对赌博刺激表现出更强的偏见的假设。相比之下，非赌徒对与食物相关的图像表现出明显的偏好，正如IS模型所预测的那样。此外，群体差异表明，赌徒比非赌徒更关注与赌博有关的线索。然而，与中性图片相比，食物图片引起的赌徒和非赌徒的注意力水平相似，而不是与赌博有关的图片。这些发现强调了ABs在赌博行为发展和维持中的作用，支持IS模型，但不支持RDS模型。本研究还探讨了AB与赌博严重程度及赌博障碍中其他相关心理因素的关系，为赌博成瘾的认知机制提供了新的见解。这些结果表明，ABs可以作为干预的目标，旨在改变注意力模式和减少赌博相关的渴望。

Electrophysiological measures are being increasingly utilized for the study of developmental changes in children. Accordingly, how alpha oscillation may play an important role in child development is of particular interest. This study aimed to better understand the development of alpha rhythm with age in childhood and its relationship with working memory capability. We collected eyes-open resting-state electroencephalogram (EEG) data of 253 children aged 3 to 9 years to explore the development of brain rhythm of the alpha band with age and then explored the relationship between working memory span task and EEG alpha activity. The results demonstrated age-related decline trend in the relative power of delta band and theta band, age-depend increase in the beta 1 band across all regions and beta 2 band in the central and occipital regions, as well as a shifting pattern of the peak alpha frequency towards a higher frequency range with age. Regarding the spatial distribution pattern, the alpha band power showed a similar distribution between adjacent frequencies, and developed towards higher frequencies, especially in the central and occipital regions. Moreover, correlation analysis results demonstrated a positive correlation between the relative power of the alpha 2 band (10–13 Hz) in resting-state EEG and the working memory capacities of children. Higher scores of the longest digital span recalled were correlated with higher resting-state alpha power. This study's findings underscore the significance of the temporal region and the right central region for children's working memory development.

电生理测量越来越多地用于研究儿童的发育变化。因此，α振荡如何在儿童发育中发挥重要作用是人们特别感兴趣的。本研究旨在更好地了解儿童时期α节律随年龄的发展及其与工作记忆能力的关系。本文收集253例3 ~ 9岁儿童睁眼静息状态脑电图（EEG）数据，探讨脑α带节律随年龄的发展，进而探讨工作记忆广度任务与脑电图α活动的关系。结果表明，δ波段和θ波段的相对强度随年龄的增长呈下降趋势，β 1波段的相对强度随年龄的增长而增加，β 2波段的相对强度随年龄的增长而增加，α峰值频率随年龄的增长而向更高的频率范围移动。在空间分布格局上，α波段功率在相邻频率间呈现相似分布，并向高频方向发展，特别是在中央区和枕区。此外，相关分析结果显示静息状态脑电图α 2波段（10 ~ 13 Hz）的相对功率与儿童的工作记忆能力呈正相关。记忆的最长数字广度得分越高，静息状态阿尔法能量越高。本研究的发现强调了颞区和右中央区域对儿童工作记忆发展的重要性。

Goal conflict is central to anxiety processing, but certain forms of goal conflict, such as avoid-avoid, remain under-investigated in EEG research. This study adapted the Joystick Operated Runway Task (JORT) for use with EEG to explore neural biomarkers of goal conflict related to the Behavioural Inhibition System (BIS), a key component of Reinforcement Sensitivity Theory (RST). A novel Trial Calibration System (TCS) was implemented to control motor activity and equate task difficulty across participants during high and low conflict conditions. Forty right-handed participants (aged 18–24) completed the EEG-adapted JORT, where conflict was manipulated by varying the speed of aversive stimuli. Behavioural data confirmed effective goal conflict induction: high conflict trials produced slower reaction times, more joystick movements, and a performance accuracy near 52 %, indicating a balanced conflict. EEG analyses using Current Source Density (CSD) transformations revealed increased right-frontal theta power and coherence during high conflict trials, consistent with BIS engagement. Left-frontal alpha power and coherence were more prominent during low conflict, while high conflict also produced elevated alpha power in parieto-occipital regions, suggesting roles in early threat detection and sensory integration. These results suggest that avoid-avoid goal conflict reliably activates BIS-related neural systems and that the updated JORT provides a valid method for studying anxiety-related biomarkers. Using a motor-calibrated framework, this is the first study to integrate EEG with an avoid-avoid conflict paradigm. Future work should examine pharmacological modulation and include clinical samples to further validate the specificity of the observed neural patterns for anxiety-related conflict processing.

目标冲突是焦虑处理的核心，但某些形式的目标冲突，如回避-回避，在脑电图研究中仍未得到充分研究。本研究将操纵杆操作跑道任务（JORT）与脑电图结合使用，探索与行为抑制系统（BIS）相关的目标冲突的神经生物标志物，这是强化敏感性理论（RST）的一个关键组成部分。采用一种新颖的试验校准系统（TCS）来控制高冲突和低冲突条件下被试的运动活动和任务难度。40名右撇子参与者（18-24岁）完成了适应脑电图的JORT，其中通过改变厌恶刺激的速度来操纵冲突。行为数据证实了有效的目标冲突诱导：高冲突试验产生较慢的反应时间，更多的操纵杆运动，以及接近52%的表现准确性，表明平衡冲突。使用电流源密度（CSD）变换的脑电图分析显示，在高冲突试验中，右额波功率和相干性增加，与BIS参与一致。在低冲突状态下，左额叶α能量和连贯性更为突出，而高冲突状态下，顶枕叶α能量也会升高，提示在早期威胁检测和感觉整合中起作用。这些结果表明，避免-避免目标冲突可靠地激活了bis相关的神经系统，并且更新的JORT为研究焦虑相关的生物标志物提供了有效的方法。使用电机校准框架，这是第一个将脑电图与避免-避免冲突范式相结合的研究。未来的工作应该检查药理学调节和包括临床样本，以进一步验证观察到的焦虑相关冲突处理的神经模式的特异性。

Homophones share identical pronunciations but differ in spelling and meaning, presenting a challenge in language acquisition. This study investigated whether the phonological familiarity of novel homophones aids the learning of orthographic forms and meanings or whether a mismatch between familiar sounds and new orthography creates obstacles to acquisition. Using Russian words, we created pseudohomophones that are identical in pronunciation to familiar words but have different spellings, as well as non-homophonic pseudowords that differ from familiar words in both pronunciation and spelling. Twenty-eight participants learned pseudohomophones and pseudowords in two experiments. We assessed orthographic and semantic acquisition using behavioral tasks and evaluated neural responses before and after learning using ERPs. Pseudohomophones were learned faster and their orthographic forms acquired better than those of pseudowords. Before learning, pseudowords elicited a larger N400 than familiar words, whereas pseudohomophones did not differ significantly, suggesting that phonological similarity hindered their distinction from real words. After learning, pseudowords showed modulations in the P200, N250-P325, and P600 components, reflecting the formation of new orthographic, phonological, and semantic representations. In contrast, only the P600 was modulated for pseudohomophones, likely because their phonology was already familiar. Moreover, comparison between pseudohomophones and pseudowords revealed greater modulation in frontal regions around 300 ms for pseudowords due to the learning session, indicating the formation of phonological representations and increased attentional demands. These findings are compatible with the connectionist dual-process model, suggesting a learning advantage for pseudohomophones based on existing phonological representations.

同音异义词发音相同，但拼写和意义不同，给语言习得带来了挑战。本研究探讨了新同音同义词的语音熟悉是否有助于正字法形式和意义的学习，或者熟悉的声音和新正字法之间的不匹配是否会造成习得障碍。使用俄语单词，我们创造了与熟悉的单词发音相同但拼写不同的假同音词，以及在发音和拼写上与熟悉的单词不同的非同音假词。在两个实验中，28名参与者学习了假同音异义词和假单词。我们使用行为任务评估正字法和语义习得，并使用erp评估学习前后的神经反应。假同音异义词的学习速度较快，其正字法的习得也优于假词。在学习前，假词诱发的N400比熟悉词大，而假同音异义词诱发的N400差异不显著，这表明语音相似性阻碍了假词与真实词的区分。学习后，假词在P200、N250-P325和P600成分中出现了调制，反映了新的正字法表征、语音表征和语义表征的形成。相比之下，只有P600对假同音异义词进行了调制，可能是因为它们的音系已经很熟悉了。此外，假同音同义词和假词的对比显示，假词在300 ms左右时，由于学习过程，额叶区域的调制更大，这表明语音表征的形成和注意需求的增加。这些发现与连接主义双过程模型相一致，表明基于现有语音表征的假同音同义词具有学习优势。

The processing of emotional words plays a crucial role in everyday communication, yet the neurocognitive mechanisms underlying this process remain insufficiently understood. One particularly important question is whether and how emotion-label words (e.g., “happy,” “sad”) and emotion-laden words (e.g., “beauty,” “failure”) differ in neural processing. The present study investigated this issue by recording event-related potentials (ERPs) during a lexical decision task. Fifty-two native Chinese speakers were asked to classify 150 real words (30 positive-label, 30 positive-laden, 30 negative-label, 30 negative-laden, and 30 neutral words) and 150 pseudowords. Behavioral results showed faster reaction times and higher accuracy rates for emotion-label words compared to emotion-laden words. A data-driven mass univariate analysis revealed a significant frontal negative ERP deflection for emotion-label words relative to emotion-laden words around 400 ms after word onset. This emotional frontal effect around 400 ms (labeled as e-FN400) emerged as the most robust ERP difference between the two emotional word types, suggesting unique neurocognitive mechanisms engaged by emotion-label words. Possible functional roles of the e-FN400 are discussed, including its potential reflection of greater semantic density, enhanced episodic familiarity, and stronger embodied emotional activation associated with emotion-label words.

情绪词汇的处理在日常交流中起着至关重要的作用，但这一过程背后的神经认知机制仍未得到充分的了解。一个特别重要的问题是，带有情绪标签的词（如“快乐”、“悲伤”）和带有情绪的词（如“美丽”、“失败”）在神经处理过程中是否不同，以及如何不同。本研究通过记录词汇决策任务中的事件相关电位（erp）来研究这一问题。要求52名以汉语为母语的人对150个真实单词（30个积极标签词、30个积极标签词、30个消极标签词、30个消极标签词和30个中庸词）和150个假词进行分类。行为测试结果显示，与充满情绪的词汇相比，带有情绪标签的词汇反应速度更快，准确率更高。一项数据驱动的大规模单变量分析显示，在单词开始后400毫秒左右，情绪标签词相对于情绪负载词的正面负ERP偏转显著。400毫秒左右的情绪额叶效应（标记为e-FN400）是两种情绪词类型之间最强大的ERP差异，表明情绪标签词参与的独特神经认知机制。讨论了e-FN400可能的功能作用，包括它可能反映更大的语义密度、增强的情景熟悉度和与情绪标签词相关的更强的具身情绪激活。

Synergistic prioritization in memory: Electrophysiological evidence for metamemory-driven automatic and strategic mechanisms 记忆中的协同优先化：元记忆驱动的自动和策略机制的电生理证据

Adaptively prioritizing high-value information is crucial for maximizing memory efficiency. Although recent research has demonstrated that prioritization in value-directed remembering relies on automatic and strategic mechanisms, it is controversial whether these mechanisms operate independently or synergistically to enhance memory selectivity. In particular, the neural correlations of how the underlying metamemory regulates these processes remain unclear. Thirty healthy adults completed an adapted value-directed remembering paradigm in which metamemory was manipulated through pre-encoding cues indicating the upcoming test form (recognition/free recall/unknown). During the encoding phase, participants studied high- and low-value words, and event-related potentials (ERPs) and time-frequency activity were recorded to examine the roles of automatic and strategic mechanisms, which was followed by a cued recall test. The results revealed that metamemory modulated resource allocation via N400 and frontal slow wave amplitudes and strategic selection through alpha- and theta-band time-frequency activity, collectively influencing the strategic mechanism. Specifically, time-frequency activity in the theta band related to the suppression of low-value items was more strongly correlated with memory selectivity than was time-frequency activity in the alpha band related to the selection of high-value items. The automatic mechanism indexed by the P2 amplitude is dynamically adapted to engage with the strategic mechanism. These findings provide the first neurophysiological evidence for metamemory-driven synergy between automatic and strategic mechanisms, validating responsible remembering theory.

自适应地确定高价值信息的优先级对于最大化内存效率至关重要。虽然最近的研究表明，价值导向记忆的优先次序依赖于自动和策略机制，但这些机制是独立运作还是协同运作以提高记忆选择性仍存在争议。特别是，潜在的元记忆如何调节这些过程的神经相关性仍然不清楚。30名健康成人完成了适应性价值导向记忆范式，在该范式中，元记忆通过提示即将到来的测试形式（识别/自由回忆/未知）的预编码线索来操纵。在编码阶段，被试研究了高值词和低值词，并记录了事件相关电位（ERPs）和时间频率活动，以检验自动机制和策略机制的作用，随后进行了线索回忆测试。结果表明，元记忆通过N400调节资源分配，通过额叶慢波振幅调节资源分配，通过α和θ波段时频活动调节策略选择，共同影响策略机制。具体而言，与抑制低价值项目相关的θ波段时频活动与记忆选择性的相关性比与选择高价值项目相关的α波段时频活动更强。以P2振幅为索引的自动机制动态适应于与战略机制的接触。这些发现为元记忆驱动的自动机制和策略机制之间的协同作用提供了第一个神经生理学证据，验证了负责任记忆理论。至关重要的是，我们的结果挑战了选择性增强占主导地位的传统观点，而是强调了抑制在优先编码中的关键作用。

Although recent research has demonstrated that prioritization in value-directed remembering relies on automatic and strategic mechanisms, it is controversial whether these mechanisms operate independently or synergistically to enhance memory selectivity.

Thirty healthy adults completed an adapted value-directed remembering paradigm in which metamemory was manipulated through pre-encoding cues indicating the upcoming test form (recognition/free recall/unknown). During the encoding phase, participants studied high- and low-value words, and event-related potentials (ERPs) and time-frequency activity were recorded to examine the roles of automatic and strategic mechanisms, which was followed by a cued recall test. The results revealed that metamemory modulated resource allocation via N400 and frontal slow wave amplitudes and strategic selection through alpha- and theta-band time-frequency activity, collectively influencing the strategic mechanism. Specifically, time-frequency activity in the theta band related to the suppression of low-value items was more strongly correlated with memory selectivity than was time-frequency activity in the alpha band related to the selection of high-value items.

Multiverse analyses strengthen the robustness of psychophysiological research by evaluating the influence of various analytical choices on results. The relationship between neural measures of inhibitory control and food intake is one area where researchers face multiple analytical decisions regarding inclusion and operationalization of variables. Although individuals with higher inhibitory control generally exhibit better diet-related outcomes, the relationship between event-related potential (ERP) markers of inhibitory control and food intake is inconsistent, calling into question the reliability of results. We conducted a multiverse analysis where 16 models were used to test a multiverse of relationships between ERP indices of inhibitory control and caloric or carbohydrate intake while controlling for age, biological sex, weight, and body mass index (BMI). No-go and difference (i.e., no-go minus go) amplitudes for N2 and P3 ERP components were used as indices of inhibitory control. Across four independent studies, 288 participants (M_age = 25.89, SD_age = 7.50) completed a high-calorie go/no-go task while ERP data were recorded. Food intake was recorded using the online Automated Self-Administered 24-hour Dietary Assessment Tool. Results generally found no significant relationship between ERP measures and calorie or carbohydrate intake. Biological males, heavier individuals, and those with higher BMIs tended to consume more food. Inhibitory control, as measured by the N2 and P3 ERP components during a high-calorie go/no-go task, does not consistently relate to food intake in the current multiverse analysis. Other cognitive and diet-related factors, like reward sensitivity and dietary restraint, need consideration when testing the link between inhibitory control and diet.

多元宇宙分析通过评估各种分析选择对结果的影响，加强了心理生理学研究的稳健性。抑制控制和食物摄入的神经测量之间的关系是一个领域，研究人员面临多个分析决策关于变量的包含和操作化。尽管具有较高抑制控制的个体通常表现出更好的饮食相关结果，但抑制控制的事件相关电位（ERP）标记物与食物摄入之间的关系并不一致，这使结果的可靠性受到质疑。在控制年龄、生理性别、体重和体重指数（BMI）的情况下，我们使用了16个模型来检验抑制控制的ERP指数与热量或碳水化合物摄入量之间的多重关系。N2和P3 ERP成分的No-go和差（即No-go -go）振幅作为抑制控制的指标。在四项独立研究中，288名参与者（Mage = 25.89,SDage = 7.50）完成了高热量的go/no-go任务，同时记录了ERP数据。使用在线自动自我管理24小时饮食评估工具记录食物摄入量。结果普遍发现ERP测量与卡路里或碳水化合物摄入之间没有显著关系。生理上的男性、体重较重的个体和bmi较高的个体倾向于消耗更多的食物。在当前的多元宇宙分析中，在高热量的“去”/“不去”任务中，抑制控制由N2和P3 ERP成分测量，与食物摄入并不一致。在测试抑制控制和饮食之间的联系时，需要考虑其他认知和饮食相关因素，如奖励敏感性和饮食限制。

Phase-amplitude coupling (PAC) plays a critical role in attention, sensory processing, and working memory—domains often impaired in children with attention deficit/hyperactivity disorder (ADHD). Therefore, PAC is theoretically well-suited for ADHD research. However, the differences in PAC characteristics among children with ADHD subtypes have not yet been thoroughly investigated. This study recorded resting-state electroencephalographic (rsEEG) from 19 healthy controls (HCs), 33 children with predominantly inattentive type (ADHD-I), and 39 with combined type (ADHD-C). We examined intra- and inter-channel PAC differences across different spatial scales and further analyzed PAC-based brain network properties. The results showed that both ADHD subtypes had stronger α-γ PAC than HCs, with ADHD-C exceeding ADHD-I. ADHD-I showed mainly intrahemispheric changes, while ADHD-C involved the left hemisphere and occipital regions. In the α-β band, PAC was significantly higher in ADHD-C than in ADHD-I, mostly in the left brain. ADHD-I also showed increased inter-channel δ-β PAC compared to HCs, with widespread distribution. These findings suggest the presence of compensatory hyperactivation mechanisms in ADHD, particularly in the ADHD-C subtype. Further brain network analysis supported the “delayed maturation theory” of ADHD and indicated that ADHD-C may represent a shift from a typical small-world network architecture to a more regular network organization. Finally, the (Support Vector Machine) SVM classification results further validated the discriminative power of these features in differentiating HCs from ADHD subtypes. Overall, these findings indicate significant differences in PAC strength and brain network topology among ADHD subtypes, suggesting their potential as biomarkers for distinguishing HCs from ADHD subtypes.

相位振幅耦合（PAC）在注意缺陷/多动障碍（ADHD）儿童的注意、感觉加工和工作记忆领域中起着关键作用。因此，PAC在理论上非常适合于ADHD的研究。然而，ADHD亚型儿童PAC特征的差异尚未被彻底研究。本研究记录了19名健康对照（hc）、33名主要注意力不集中型（ADHD-I）儿童和39名混合型（ADHD-C）儿童的静息状态脑电图（rsEEG）。我们研究了通道内和通道间PAC在不同空间尺度上的差异，并进一步分析了基于PAC的脑网络特性。结果显示，两种ADHD亚型均有较强的α-γ PAC，且ADHD- c亚型均超过ADHD- i亚型。adhd - 1主要表现为半球内改变，而ADHD-C涉及左半球和枕区。在α-β带，PAC在ADHD-C中明显高于ADHD-I，且主要在左脑。与hc相比，ADHD-I也表现出通道间δ-β PAC增加，且分布广泛。这些发现表明ADHD存在代偿性过度激活机制，特别是ADHD- c亚型。进一步的大脑网络分析支持ADHD的“延迟成熟理论”，并表明ADHD- c可能代表着从典型的小世界网络结构向更规则的网络组织的转变。最后，（支持向量机）SVM分类结果进一步验证了这些特征在区分hc与ADHD亚型方面的判别能力。总的来说，这些发现表明ADHD亚型之间PAC强度和大脑网络拓扑结构存在显著差异，这表明它们有可能作为区分hc和ADHD亚型的生物标志物。
