    为了检查不同程度多动症儿童的认知控制缺陷的表现,ADHD的“有风险”维度。
    一组多动症儿童(N=40)和另一组多动症儿童(N=38)进行了修改的停止信号预测任务,修改后的Go/NoGo任务,以及AX-连续性能测试(AX-CPT)。
    显示的多动症儿童:(1)在修改后的停止信号预期任务中,停止信号反应时间(SSRT)显着延长;(2)在修改后的Go/NoGo任务中,佣金错误没有显着差异;(3)停止信号任务和Go/NoGo任务的反应时间(RT)增加,停止或NoGo信号的概率增加;(4)积极的CPAX行为指数
    结果表明,多动症儿童表现出反应控制受损,特别是对于已经在进行的回应,但保持了主动控制。有必要对这些儿童进行进一步的研究。
    UNASSIGNED: To examine the manifestation of cognitive control deficit of children with different levels of hyperactivity, an \"at risk\" dimension for ADHD.
    UNASSIGNED: A group of children with high hyperactivity (N = 40) and another group of children with low levels of hyperactivity (N = 38) performed a modified stop-signal anticipation task, a revised Go/NoGo task, and the AX-continuous performance test (AX-CPT).
    UNASSIGNED: Children with higher levels of hyperactivity displayed: (1) significantly prolonged stop signal reaction time (SSRT) in the modified stop-signal anticipation task; (2) no notable differences in commission errors in the revised Go/NoGo task; (3) increased reaction time (RT) in stop-signal task and Go/NoGo task with increased probabilities of stop or NoGo signal; and (4) positive proactive behavioral index scores in AX-CPT.
    UNASSIGNED: The results suggested that children with heightened hyperactivity exhibited impaired reactive control, especially for responses already underway, but preserved proactive control. Further studies concerning these children are warranted.

    这项研究的目的是研究直接测量和父母评估的执行功能在预测儿童的学业成绩和社会发展之间的差异,并探讨同伴地位和社会能力在执行功能对社会行为影响中的中介作用。
    这项研究追踪了中国一所小学的106名一年级儿童,为期一年。使用SPSS26.0和AMOS21.0进行回归和中介分析以检验假设。
    首先,在比较直接测量和父母评估的执行功能的预测作用时,直接测量的执行功能在预测学业成绩方面发挥了更重要的作用,而父母评估的执行功能在预测社会发展方面发挥了更大的作用。第二,父母评估的执行功能主要通过社交能力和同伴地位影响社会行为,社交能力比同龄人地位起着更重要的中介作用。
    与以前的研究相比,本研究的结果为直接测量和父母评估的执行功能之间的关系和差异提供了更直接的证据,进一步表明它们具有不同的功效和预测目标,同时,本研究还描述了执行功能影响社会行为的途径:同伴地位和社会能力的中介作用。这表明,一方面,教育工作者或研究人员需要为自己的目的选择适当的执行功能措施,另一方面,为了促进儿童社会行为的发展,他们需要关注儿童执行功能的发展,社交能力和同伴关系。
    UNASSIGNED: The purpose of this study was to examine differences between directly measured and parent-evaluated executive function in predicting children\'s academic achievement and social development, and to explore the mediating roles of peer status and social competence in the effects of executive function on social behavior.
    UNASSIGNED: The study followed 106 first-grade children in an elementary school in China for one year. Regression and mediation analyses were conducted using SPSS 26.0 and AMOS 21.0 to test the hypotheses.
    UNASSIGNED: First, in a comparison of the predictive role of directly measured and parent-evaluated executive function, directly measured executive function played a more important role in predicting academic achievement, while parent-evaluated executive function played a greater role in predicting social development. Second, parent-evaluated executive function influenced social behavior primarily through social competence and peer status, with social competence playing a more significant mediating role than peer status.
    UNASSIGNED: Compared with previous studies, the results of the present study provide more direct evidence for the relationship and differences between directly measured and parent-evaluated executive function, further suggesting that they have different efficacy and predictive goals, while the present study also describes the pathways through which executive function influences social behavior: the mediating role of peer status and social competence. This suggests that, on the one hand, educators or researchers need to choose appropriate measures of executive function for their own purposes and, on the other hand, in order to promote the development of children\'s social behavior, they need to focus on the development of children\'s executive function, social competence and peer relationships.

    背景:互联网游戏障碍(IGD)涉及大脑双系统的不平衡,其特点是寻求奖励和认知控制减弱,这导致了决策的挑战。勘探开发战略是决策的关键,但IGD如何影响这一过程尚不清楚。
    方法:为了调查IGD对决策的影响,采用了双臂强盗任务的修改版本。参与者包括41名IGD个体和44名健康对照(HC)个体。这项研究评估了参与者在任务中使用的策略,特别是注重开发-勘探战略。此外,功能磁共振成像(fMRI)用于检查决策和估计阶段的大脑激活模式。
    结果:研究发现,IGD患者在决策中表现出对剥削策略的更高依赖,因为他们的价值追求倾向升高,认知控制下降。在决策和估计阶段,与HC组相比,IGD个体在补充前运动区(preSMA)和腹侧纹状体(VS)中也显示出增强的激活。同时,在开发策略期间,IGD个体的前额叶皮质(PFC)表现出比HC组更多的抑制作用.发现这种抑制作用随着认知控制的减少而减少。
    结论:该研究得出结论,IGD患者双元系统发展的不平衡可能导致对剥削策略的过度依赖。这种不平衡,以增加寻求奖励和减少认知控制为标志,导致IGD个体的决策困难和与价值相关的行为过程。
    BACKGROUND: Internet Gaming Disorder (IGD) involves an imbalance in the brain\'s dual-system, characterized by heightened reward-seeking and diminished cognitive control, which leads to decision-making challenges. The exploration-exploitation strategy is key to decision-making, but how IGD affects this process is unclear.
    METHODS: To investigate the impact of IGD on decision-making, a modified version of the two-armed bandit task was employed. Participants included 41 IGD individuals and 44 healthy control (HC) individuals. The study assessed the strategies used by participants in the task, particularly focusing on the exploitation-exploration strategy. Additionally, functional magnetic resonance imaging (fMRI) was used to examine brain activation patterns during decision-making and estimation phasess.
    RESULTS: The study found that individuals with IGD demonstrated a higher reliance on exploitative strategies in decision-making due to their elevated value-seeking tendencies and decreased cognitive control. IGD individuals also displayed heightened activation in the pre-supplementary motor area (preSMA) and the ventral striatum (VS) compared to the HC group in both decision-making and estimation phases. Meanwhile, the prefrontal cortex (PFC) showed more inhibition in IGD individuals than in the HC group during exploitative strategies. This inhibition was found to decrease as cognitive control diminished.
    CONCLUSIONS: The study concludes that the imbalance in the development of the dual-system in individuals with IGD may lead to an over-reliance on exploitative strategies. This imbalance, marked by increased reward-seeking and reduced cognitive control, contributes to difficulties in decision-making and value-related behavioral processes in IGD individuals.

    Mental subtraction, involving numerical processing and operation, requires a complex interplay among several brain regions. Diverse studies have utilized scalp electroencephalograph, electrocorticogram, or functional magnetic resonance imaging to resolve the structure pattern and functional activity during subtraction operation. However, a high resolution of the spatial-temporal understanding of the neural mechanisms involved in mental subtraction is unavailable. Thus, this study obtained intracranial stereoelectroencephalography recordings from 20 patients with pharmacologically resistant epilepsy. Specifically, two sample-delayed mismatch paradigms of numeric comparison and subtracting results comparison were used to help reveal the time frame of mental subtraction. The brain sub-regions were chronologically screened using the stereoelectroencephalography recording for mental subtraction. The results indicated that the anterior cortex, containing the frontal, insular, and parahippocampous, worked for preparing for mental subtraction; moreover, the posterior cortex, such as parietal, occipital, limbic, and temporal regions, cooperated during subtraction. Especially, the gamma band activities in core regions within the parietal-cingulate-temporal cortices mediated the critical mental subtraction. Overall, this research is the first to describe the spatiotemporal activities underlying mental subtraction in the human brain. It provides a comprehensive insight into the cognitive control activity underlying mental arithmetic.

    认知功能和情绪调节之间的联系可能有助于更好地理解发病,维护,和治疗抑郁症。然而,目前尚不清楚抑郁患者的情绪失调和认知缺陷之间是否存在神经相关性.为了解决这个问题,我们首先回顾了抑郁症中情绪失调和认知缺陷(包括认知控制缺陷和认知偏差)的神经表现。基于情绪失调与认知缺陷的神经表征的比较,我们提出了情绪失调之间的可访问和合理的联系,认知控制,和抑郁症的认知偏见。具体来说,认知控制服务于情绪调节的全过程,而认知偏差在不同阶段参与情绪调节过程。此外,不同情绪调节策略在抑郁症中的异常执行始终受到认知控制的影响,涉及背外侧,背侧前额叶皮层,和前扣带皮质。此外,不同的情绪调节策略与抑郁症认知偏差之间的关系可能是不同的:眶额叶皮层有助于无效的重新评价和负面解释偏差之间的关联,而后代前额叶皮层和后扣带皮层强调了抑郁个体反思性和过度参与自我参照偏见的趋势。这篇综述阐明了抑郁症中认知缺陷与情绪失调之间的关系,并确定了未来需要关注的方向。
    The link between cognitive function and emotion regulation may be helpful in better understanding the onset, maintenance, and treatment for depression. However, it remains unclear whether there are neural correlates between emotion dysregulation and cognitive deficits in depression. To address this question, we first review the neural representations of emotion dysregulation and cognitive deficits in depression (including deficits in cognitive control and cognitive biases). Based on the comparisons of neural representations of emotion dysregulation versus cognitive deficits, we propose an accessible and reasonable link between emotion dysregulation, cognitive control, and cognitive biases in depression. Specifically, cognitive control serves the whole process of emotion regulation, whereas cognitive biases are engaged in emotion regulation processes at different stages. Moreover, the abnormal implementation of different emotion regulation strategies in depression is consistently affected by cognitive control, which is involved in the dorsolateral, the dorsomedial prefrontal cortex, and the anterior cingulate cortex. Besides, the relationship between different emotion regulation strategies and cognitive biases in depression may be distinct: the orbitofrontal cortex contributes to the association between ineffective reappraisal and negative interpretation bias, while the subgenual prefrontal cortex and the posterior cingulate cortex underline the tendency of depressed individuals to ruminate and overly engage in self-referential bias. This review sheds light on the relationship between cognitive deficits and emotion dysregulation in depression and identifies directions in need of future attention.

    先前的研究表明,警觉性与执行控制功能密切相关,但它对错误后调整部分的影响是未知的。本研究应用了注意网络测试和具有三个响应刺激间隔(RSIs)的四选择Flanker任务,以探索警觉性与错误后调整之间的相关性。警觉性和RSI对误差后处理指标的线性混合效应模型显示,200msRSI下的警觉性和误差后减慢(PES)与700msRSI和1200msRSI下的误差后精度提高(PIA)之间呈显着负相关。警觉性较低的参与者在早期阶段表现出较大的错误后放缓,而警觉性较高的人在后期的PIA较小。这项研究揭示了警觉性对错误后调整的不同处理组件的影响。具有高警觉性和低警觉性的个体所采用的控制策略在为绩效监测做准备时有所不同。警觉性以任务非特定的方式提高了错误后的响应速度,但不是错误后适应。
    Previous studies have shown that alertness is closely related to executive control function, but its impact on components of post-error adjustment is unknown. This study applied the Attentional Networks Test and the Four-choice Flanker task with three response stimulus intervals (RSIs) to explore the correlation between alertness and post-error adjustment. The linear mixed-effects model of alertness and RSI on the post-error processing indicators showed a significant negative correlation between the alertness and post-error slowing (PES) under 200 ms RSI , as well as between alertness and post-error improvement in accuracy (PIA) under both 700 ms RSI and 1200 ms RSI. Participants with lower alertness showed larger post-error slowing in the early stages, while those with higher alertness had smaller PIA in later stages. This study revealed the effects of alertness on different processing components of post-error adjustment. The control strategies utilized by individuals with high and low levels of alertness differed in preparation for performance monitoring. Alertness improved post-error response speed in a task-unspecific manner, but not post-error adaptation.

    存储在工作记忆中的信息可以指导感知选择,这个过程是由认知控制来调节的。尽管先前的研究表明,左背外侧前额叶皮层(lDLPFC)的神经刺激有助于恢复物质使用障碍(SUD)患者的认知控制,关于对记忆驱动的注意力的潜在刺激作用,仍然存在一个悬而未决的问题。为了解决这个问题,本研究采用复合工作记忆/注意力模式,同时采用高清晰度经颅直流电刺激(HD-tDCS)刺激lDLPFC.观察者被要求在执行搜索任务时在内存中维护视觉或视听信息,而后续搜索任务的内存内容的有效性可能是无效的或中性的。结果表明,仅在视听条件下,在假刺激中,记忆驱动的注意力抑制作用微弱。此外,在仅视觉条件下,阳极HD-tDCS在强度和时间动力学中都促进了注意力抑制作用,而在视听条件下效果受损或不变。令人惊讶的是,在视听条件下,阴极HD-tDCS选择性地改善了注意力抑制效果的时间动力学。本研究揭示了HD-tDCS对SUD患者对视觉和视听记忆驱动的注意力的认知控制的差异增强。
    Information stored in working memory can guide perception selection, and this process is modulated by cognitive control. Although previous studies have demonstrated that neurostimulation over the left dorsolateral prefrontal cortex (lDLPFC) contributes to restore cognitive control among individuals with substance use disorder (SUD), there remains an open question about the potential stimulation effects on memory-driven attention. To address this issue, the present study adopted a combined working memory/attention paradigm while employing high-definition transcranial direct current stimulation (HD-tDCS) to stimulate the lDLPFC. Observers were asked to maintain visual or audiovisual information in memory while executing a search task, while the validity of the memory contents for the subsequent search task could be either invalid or neutral. The results showed a faint memory-driven attentional suppression effect in sham stimulation only under the audiovisual condition. Moreover, anodal HD-tDCS facilitated attentional suppression effect in both the strength and temporal dynamics under the visual-only condition, whereas the effect was impaired or unchanged under the audiovisual condition. Surprisingly, cathodal HD-tDCS selectively improved temporal dynamics of the attentional suppression effect under the audiovisual condition. The present study revealed the differential enhancement of HD-tDCS on cognitive control over visual and audiovisual memory-driven attention among individuals with SUD.

    在更持久和更灵活的认知控制方式之间找到正确平衡的能力被称为“元控制”。“最近的研究结果表明,非周期性脑电图活动和任务条件的相关性可能会引起特定的元控制方式。在这里,我们研究了在任务外(在静息状态下)获得的非周期性EEG活动的个体差异是否可以预测在对元控制提出不同要求的任务条件下的个体认知控制方式。我们分析了EEG静息状态数据,任务脑电图,和来自N=65名执行Go/Nogo任务的健康参与者样本的行为结果。我们检查了非周期性活动,作为EEG功率谱中“神经噪声”的指标,根据静息状态下获得的指数的中位数分裂,将参与者分配到高噪声或低噪声组.我们发现,非任务非周期性指数在Go和Nogo条件下预测了不同的认知控制方式:总体而言,非周期性指数较高(即,噪音较低)在低噪声组中,然而,他们在围棋和诺戈试验之间没有区别,而高噪声组在持久性较重的Nogo条件下表现出显着的降噪效果。这表明类似特质的偏见决定了默认的认知控制方式,然而,在具有挑战性的任务要求下,这可以被覆盖或补偿。我们建议EEG信号中的非周期性活动代表元控制样式之间高度动态仲裁的有效指标,代表大脑重组自身并使其神经活动模式适应不断变化的环境条件的能力。
    The ability to find the right balance between more persistent and more flexible cognitive-control styles is known as \"metacontrol.\" Recent findings suggest a relevance of aperiodic EEG activity and task conditions that are likely to elicit a specific metacontrol style. Here we investigated whether individual differences in aperiodic EEG activity obtained off-task (during resting state) predict individual cognitive-control styles under task conditions that pose different demands on metacontrol. We analyzed EEG resting-state data, task-EEG, and behavioral outcomes from a sample of N = 65 healthy participants performing a Go/Nogo task. We examined aperiodic activity as indicator of \"neural noise\" in the EEG power spectrum, and participants were assigned to a high-noise or low-noise group according to a median split of the exponents obtained for resting state. We found that off-task aperiodic exponents predicted different cognitive-control styles in Go and Nogo conditions: Overall, aperiodic exponents were higher (i.e., noise was lower) in the low-noise group, who however showed no difference between Go and Nogo trials, whereas the high-noise group exhibited significant noise reduction in the more persistence-heavy Nogo condition. This suggests that trait-like biases determine the default cognitive-control style, which however can be overwritten or compensated for under challenging task demands. We suggest that aperiodic activity in EEG signals represents valid indicators of highly dynamic arbitration between metacontrol styles, representing the brain\'s capability to reorganize itself and adapt its neural activity patterns to changing environmental conditions.

    这项研究调查了认知控制在道德决策中的作用,关注财务诱惑与诚信之间的冲突。我们通过要求参与者识别对角线的哪一侧在正方形内包含更多的红点来挑起诚实和不诚实的行为来进行感知任务,跟踪他们的反应时间(RT)。参与者遇到没有冲突的情况,模棱两可的冲突,明确的冲突。他们在明确的冲突条件下的行为将他们归类为“诚实”或“不诚实”。“我们的研究结果表明,在模糊的冲突局势中,诚实的人比不诚实的人有明显更长的RT和更少的自利反应,这表明更需要认知控制来解决冲突,而更少的倾向于自我利益。此外,在模糊的冲突情况下,参与者的自利反应数量和RTs之间存在负相关(研究1中r=-0.27,研究2中r=-0.66),在明确的冲突情况下,与作弊数量呈正相关(研究1中r=0.36,研究2中r=0.82)。这表明自我利益和作弊反应需要较少的认知控制,支持“意志”假设。我们还发现,一个人的自利倾向可以预测他们的不诚实行为。这些见解扩展了我们对认知控制在诚实和不诚实中的作用的理解,在教育中的潜在应用,决策,和商业道德。
    This study investigated the role of cognitive control in moral decision-making, focusing on conflicts between financial temptations and the integrity of honesty. We employed a perceptual task by asking participants to identify which side of the diagonal contained more red dots within a square to provoke both honest and dishonest behaviors, tracking their reaction times (RTs). Participants encountered situations with no conflict, ambiguous conflict, and clear conflict. Their behaviors in the clear conflict condition categorized them as either \"honest\" or \"dishonest.\" Our findings suggested that, in ambiguous conflict situations, honest individuals had significantly longer RTs and fewer self-interest responses than their dishonest counterparts, suggesting a greater need for cognitive control to resolve conflicts and a lesser tendency toward self-interest. Moreover, a negative correlation was found between participants\' number of self-interest responses and RTs in ambiguous conflict situations (r = -0.27 in study 1 and r = -0.66 in study 2), and a positive correlation with cheating numbers in clear conflict situations (r = 0.36 in study 1 and r = 0.82 in study 2). This suggests less cognitive control was required for self-interest and cheating responses, bolstering the \"Will\" hypothesis. We also found that a person\'s self-interest tendency could predict their dishonest behavior. These insights extend our understanding of the role of cognitive control plays in honesty and dishonesty, with potential applications in education, policy-making, and business ethics.

    任务转换是指将注意力从一个任务转移到另一个任务所涉及的一组认知过程。近年来,研究人员应用经颅直流电刺激(tDCS)来研究顶叶皮层与任务切换之间的因果关系.然而,现有研究的结果高度不一致.这可能是由于对潜在机制的不清楚理解。因此,本研究利用事件相关电位(ERP)分析来研究tDCS对任务切换过程的调节作用.招募了24名受试者,在阳极(RA)和假条件下执行可预测和不可预测的奇偶校验/幅度任务。结果显示行为表现没有显著变化。然而,观察到明显的tDCS诱导的ERP变化。具体来说,对于可预测的任务切换,与假条件相比,在男性RA条件下,转换试验的目标N2成分明显早于重复试验,而在女性中没有发现差异。对于不可预测的任务切换,在假条件下,与重复试验相比,转换试验的P2峰值明显更大,而在RA条件下没有观察到这种差异。这些结果表明,右顶叶皮层与任务转换中涉及的外源调节过程之间存在因果关系。此外,右侧顶叶皮层的阳极tDCS可能导致性别差异的表现。
    Task switching refers to a set of cognitive processes involved in shifting attention from one task to another. In recent years, researchers have applied transcranial direct current stimulation (tDCS) to investigate the causal relationship between the parietal cortex and task switching. However, results from available studies are highly inconsistent. This may be due to the unclear understanding of the underlying mechanisms. Therefore, the current study utilized event-related potential (ERP) analysis to investigate the modulatory effects of tDCS on task-switching processes. Twenty-four subjects were recruited to perform both predictable and unpredictable parity/magnitude tasks under anodal (RA) and sham conditions. The results showed no significant changes in behavioral performance. However, marked tDCS-induced ERP changes were observed. Specifically, for the predictable task switching, compared with the sham condition, the target-N2 component occurred significantly earlier for switch trials than repeat trials under the RA condition in males, while no difference was found in females. For unpredictable task switching, under the sham condition, the P2 peak was significantly larger for switch trials compared with repeat trials, whereas this difference was not observed under the RA condition. These results indicated the causal relationship between the right parietal cortex and exogenous adjustment processes involved in task switching. Moreover, anodal tDCS over the right parietal cortex may lead to the manifestation of gender differences.
