performance monitoring

性能监控
  • 文章类型: Journal Article
    在不同的强制选择响应任务中,性能监控已被广泛研究。参与者通常表现出更长的响应时间(RT)和错误后更高的准确性,但是错误相关的事件相关的脑电位(ERP)和行为之间的联系存在不一致,如RT和精度。任何给定研究中的特定任务都可能导致这些不一致,因为不同的任务可能需要不同的认知过程,影响ERP-行为关系。本研究旨在确定任务是否缓和了ERP-行为关系,以及当任务和刺激被视为随机效应时,这些关系是否得到了强有力的观察。ERP和行为指数(RTs,准确性)在侧翼期间记录,Stroop,来自180人的Go/Nogo任务展示了对ERP-行为关系的特定任务影响,这样,更大的先前试验错误相关的负性(ERN)预测了更长的RTs,并且在侧翼和Stroop任务期间而不是在Go/Nogo任务期间对后续试验做出正确反应的可能性更大。此外,在Stroop和Go/Nogo任务的后续试验中,较大的先前试验错误阳性(Pe)预测了较快的RT和较小的RT方差,但对于侧翼任务则没有。当任务和刺激被视为随机效应时,未观察到ERP与行为的关系。这些发现支持在解释研究结果时需要考虑用于记录性能监控措施的任务。
    Performance monitoring has been widely studied during different forced-choice response tasks. Participants typically show longer response times (RTs) and increased accuracy following errors, but there are inconsistencies regarding the connection between error-related event-related brain potentials (ERPs) and behavior, such as RT and accuracy. The specific task in any given study could contribute to these inconsistencies, as different tasks may require distinct cognitive processes that impact ERP-behavior relationships. The present study sought to determine whether task moderates ERP-behavior relationships and whether these relationships are robustly observed when tasks and stimuli are treated as random effects. ERPs and behavioral indices (RTs and accuracy) recorded during flanker, Stroop, and Go/Nogo tasks from 180 people demonstrated a task-specific effect on ERP-behavior relationships, such that larger previous-trial error-related negativity (ERN) predicted longer RTs and greater likelihood of a correct response on subsequent trials during flanker and Stroop tasks but not during Go/Nogo task. Additionally, larger previous-trial error positivity (Pe) predicted faster RTs and smaller variances of RTs on subsequent trials for Stroop and Go/Nogo tasks but not for flanker task. When tasks and stimuli were treated as random effects, ERP-behavior relationships were not observed. These findings support the need to consider the task used for recording performance monitoring measures when interpreting results across studies.

    背景:边缘性人格障碍(BPD)与冲动增强有关,证据是药物滥用增加,自我伤害和自杀企图。在患有BPD的个体中解决冲动性是一个治疗目标;但其在该临床人群中的潜在神经基础仍不清楚。部分原因是其与注意力缺陷/多动障碍(ADHD)的常见合并症。
    方法:我们在伴随的基于视频的眼动追踪期间,在诊断为BPD伴和不伴ADHD(分别为N=25和N=24)的青少年中采用了反应抑制范式-交错的前/抗扫视任务(IPAST)。我们量化了各种眼动反应参数,反映了任务过程中的脉冲动作,包括延迟获取固定,固定断裂,预期扫视,快速扫视(扫视反应时间[SRT]:90-140ms)和常规扫视延迟(SRT>140ms)的方向误差。
    结果:患有BPD的个体表现出反应准备不足,例如,对任务线索的视觉固定减少和扫视反应的更大可变性(即,SRT和峰值速度)。ADHD/BPD组共享这些特征,并产生了预期响应和方向错误的频率增加,同时具有明显的扫视延迟和减少的纠错。
    结论:BPD和ADHD/BPD的扫视缺陷不是由于无法执行反扫视,而是由于对即将到来的任务集的准备不足。这些区别可能是由于皮质区域如额叶眼场的异常信号传导而产生的,顶叶后皮质,和前扣带皮质.了解这些机制可以提供对针对任务集准备的针对性干预措施的见解,以管理BPD和ADHD/BPD中的反应抑制缺陷。
    BACKGROUND: Borderline Personality Disorder (BPD) is associated with heightened impulsivity, evidenced by increased substance abuse, self-harm and suicide attempts. Addressing impulsivity in individuals with BPD is a therapeutic objective; but its underlying neural basis in this clinical population remains unclear, partly due to its frequent co-morbidity with attention-deficit/hyperactivity disorder (ADHD).
    METHODS: We employed a response inhibition paradigm - the interleaved pro-/anti-saccade task (IPAST) - among adolescents diagnosed with BPD with and without comorbid ADHD (N=25 and N=24, respectively) during concomitant video-based eye-tracking. We quantified various eye movement response parameters reflective of impulsive action during the task, including delay to fixation acquisition, fixation breaks, anticipatory saccades, and direction errors with express saccade (Saccade Reaction Time [SRT]: 90-140 ms) and regular saccade latencies (SRT > 140 ms).
    RESULTS: Individuals with BPD exhibited deficient response preparation, exampled by reduced visual fixation on task cues and greater variability of saccade responses (i.e., SRT and peak velocity). The ADHD/BPD group shared these traits, as well as produced an increased frequency of anticipatory responses and direction errors with express saccade latencies and reduced error correction.
    CONCLUSIONS: Saccadic deficits in BPD and ADHD/BPD stem not from an inability to execute anti-saccades, but rather from an inadequate preparation for the upcoming task set. These distinctions may arise due to abnormal signaling in cortical areas like the frontal eye fields, posterior parietal cortex, and anterior cingulate cortex. Understanding these mechanisms could provide insights into targeted interventions focusing on task set preparation to manage response inhibition deficits in BPD and ADHD/BPD.

    误差相关的负性是一种广泛使用的误差监测措施,许多项目独立地将侧翼任务中记录的ERN推向标准化,优化,以及最终的临床应用。然而,每个项目使用不同版本的侧翼任务,并默认ERN在每个版本中功能等效。对这一假设的严格测试的常规忽视破坏了跨任务整合ERN结果的努力,优化和标准化ERN评估,并在临床试验中广泛应用ERN。本注册报告的目的是确定ERN是否显示出类似的实验效果(正确与在侧翼任务的三个常用版本中,错误试验)和数据质量(个体内变异性)。在两个研究地点的侧翼任务的三个版本中,从172名参与者中记录了ERN。ERN分数显示任务之间的数字差异,对跨研究和任务的ERN结果的可比性提出质疑。尽管侧翼任务的所有三个版本的ERN分数都产生了很高的数据质量和内部一致性,在实验效应的大小和数据质量方面,一个版本确实优于其他两个版本。对错误积极性(Pe)的探索性分析为该任务的其他两个版本提供了初步支持,而该范式对于ERN似乎是最佳的。本研究为如何在范式中统计比较ERP得分的心理测量特征提供了路线图,并为侧翼任务提供了初步建议,以用于以ERN和Pe为重点的研究。
    Error-related negativity is a widely used measure of error monitoring, and many projects are independently moving ERN recorded during a flanker task toward standardization, optimization, and eventual clinical application. However, each project uses a different version of the flanker task and tacitly assumes ERN is functionally equivalent across each version. The routine neglect of a rigorous test of this assumption undermines efforts to integrate ERN findings across tasks, optimize and standardize ERN assessment, and widely apply ERN in clinical trials. The purpose of this registered report was to determine whether ERN shows similar experimental effects (correct vs. error trials) and data quality (intraindividual variability) during three commonly used versions of a flanker task. ERN was recorded from 172 participants during three versions of a flanker task across two study sites. ERN scores showed numerical differences between tasks, raising questions about the comparability of ERN findings across studies and tasks. Although ERN scores from all three versions of the flanker task yielded high data quality and internal consistency, one version did outperform the other two in terms of the size of experimental effects and the data quality. Exploratory analyses of the error positivity (Pe) provided tentative support for the other two versions of the task over the paradigm that appeared optimal for ERN. The present study provides a roadmap for how to statistically compare psychometric characteristics of ERP scores across paradigms and gives preliminary recommendations for flanker tasks to use for ERN- and Pe-focused studies.

    反馈评估可以影响行为的延续或中止,对于认知和运动技能学习至关重要。影响反馈评估的一个关键因素是参与者对自我表现的内部估计。先前的研究表明,两个事件相关的潜在成分,反馈相关否定性(FRN)和P3与反馈评估相关。在本研究中,我们使用时间估计任务和脑电图记录来测试反馈和表现对参与者决策的影响,以及FRN和P3成分对这些因素的敏感性。在实验中,参与者被要求重现间歇性视觉刺激的总持续时间.每次回复后都会给出反馈,然后参与者必须决定是否重试相同的试验并尝试获得奖励积分,或者继续进行下一次审判.结果显示,绩效和反馈都影响参与者决定是否重试正在进行的试验。根据以前的研究,FRN对负反馈的响应幅度大于对正反馈的响应幅度。此外,我们的结果也与以前的工作一致,显示FRN的幅度与反馈相关的预测误差(PE)的大小之间的关系,并进一步了解体育规模如何影响参与者关于是否重试任务的决定。具体来说,我们发现FRN越大,参与者更有可能根据他们的表现做出决定-选择在表现良好后重试当前试验或在表现不佳后继续进行下一次试验,不管收到的反馈。相反,FRN越小,参与者越有可能根据收到的反馈做出决定.
    Feedback evaluation can affect behavioural continuation or discontinuation, and is essential for cognitive and motor skill learning. One critical factor that influences feedback evaluation is participants\' internal estimation of self-performance. Previous research has shown that two event-related potential components, the Feedback-Related Negativity (FRN) and the P3, are related to feedback evaluation. In the present study, we used a time estimation task and EEG recordings to test the influence of feedback and performance on participants\' decisions, and the sensitivity of the FRN and P3 components to those factors. In the experiment, participants were asked to reproduce the total duration of an intermittently presented visual stimulus. Feedback was given after every response, and participants had then to decide whether to retry the same trial and try to earn reward points, or to move on to the next trial. Results showed that both performance and feedback influenced participants\' decision on whether to retry the ongoing trial. In line with previous studies, the FRN showed larger amplitude in response to negative than to positive feedback. Moreover, our results were also in agreement with previous works showing the relationship between the amplitude of the FRN and the size of feedback-related prediction error (PE), and provide further insight in how PE size influences participants\' decisions on whether or not to retry a task. Specifically, we found that the larger the FRN, the more likely participants were to base their decision on their performance - choosing to retry the current trial after good performance or to move on to the next trial after poor performance, regardless of the feedback received. Conversely, the smaller the FRN, the more likely participants were to base their decision on the feedback received.

    基于先前的概念,在内侧额叶皮层中具有中央“集线器”的分布式theta网络与运动调节密切相关,监测,和控制,本研究探讨了随着人类年龄的增长,该网络在错误处理中的参与。为了这个目标,在一个老年人样本中,在正确和错误响应期间,在多个皮质区域分析了运动θ振荡的振荡神经动力学。在四选择反应任务中记录了正确和不正确反应的反应相关电位(RRP)。在时频域中分解RRP以提取振荡θ活性。针对功率分析了扩展电机区域的电机θ振荡,时间同步,和功能连接。主要结果表明,错误与(1)半球相对于运动外侧的theta功率增加有关,从而对内侧额叶皮层以外的皮质区域的运动theta振荡产生了显着影响,(2)抑制运动前区域相对于反应手的空间和时间同步,(2)抑制内侧额叶皮层和感觉运动区域之间的连接,(3)抑制左后半球运动θ网络的连通性和时间相位同步,不管手,左,或者对,犯了错误。误差对电动机theta振荡的分布式影响表明theta网络支持性能监控。随着年龄的增长,这些网络的重组意味着在老年人中,表现监测与内侧额叶区域的脱离以及难以控制运动注意力和反应选择的焦点有关。

    Based on previous concepts that a distributed theta network with a central \"hub\" in the medial frontal cortex is critically involved in movement regulation, monitoring, and control, the present study explored the involvement of this network in error processing with advancing age in humans. For that aim, the oscillatory neurodynamics of motor theta oscillations was analyzed at multiple cortical regions during correct and error responses in a sample of older adults. Response-related potentials (RRPs) of correct and incorrect reactions were recorded in a four-choice reaction task. RRPs were decomposed in the time-frequency domain to extract oscillatory theta activity. Motor theta oscillations at extended motor regions were analyzed with respect to power, temporal synchronization, and functional connectivity. Major results demonstrated that errors had pronounced effects on motor theta oscillations at cortical regions beyond the medial frontal cortex by being associated with (1) theta power increase in the hemisphere contra-lateral to the movement, (2) suppressed spatial and temporal synchronization at pre-motor areas contra-lateral to the responding hand, (2) inhibited connections between the medial frontal cortex and sensorimotor areas, and (3) suppressed connectivity and temporal phase-synchronization of motor theta networks in the posterior left hemisphere, irrespective of the hand, left, or right, with which the error was made. The distributed effects of errors on motor theta oscillations demonstrate that theta networks support performance monitoring. The reorganization of these networks with aging implies that in older individuals, performance monitoring is associated with a disengagement of the medial frontal region and difficulties in controlling the focus of motor attention and response selection.

    社会信息可用于优化决策。然而,多个建议来源的同时呈现可能导致在判断信息有效性时的区别性偏差。虽然已经研究了事件相关潜力(ERP)组件在社会信息处理中的参与,如何通过(错误)判断顾问的信息有效性来调节它们仍然是未知的。在两个实验中,参与者执行了具有高度准确或不准确线索的决策任务。每个实验都包括一个初始的,学习,测试阶段。在学习阶段,同时提出了三个建议提示,必须评估它们的有效性。研究了不同提示星座对ERP的影响。在随后的测试阶段,遵循或反对建议提示的意愿受到了测试。结果表明,参与者的区别偏见超过或低估了最不确定线索的准确性。当顾问意见不一致时,在提示演示期间,P2振幅显着增加,不管线索的有效性。Further,当顾问意见不一致时,在结果呈现期间发现P3振幅较大,且随着更多信息提示而增加.因此,最不确定的提示与最小的P3振幅有关.这些发现暗示了P3在判断和学习社会线索的可预测性方面的可能作用。这项研究为P2和P3组件在判断社会信息有效性方面的作用提供了新的见解。
    Social information can be used to optimize decision-making. However, the simultaneous presentation of multiple sources of advice can lead to a distinction bias in judging the validity of the information. While the involvement of event-related potential (ERP) components in social information processing has been studied, how they are modulated by (mis)judging an advisor\'s information validity remains unknown. In two experiments participants performed a decision-making task with highly accurate or inaccurate cues. Each experiment consisted of an initial, learning, and test phase. During the learning phase, three advice cues were simultaneously presented and the validity of them had to be assessed. The effect of different cue constellations on ERPs was investigated. In the subsequent test phase, the willingness to follow or oppose an advice cue was tested. Results demonstrated the distinction bias with participants over or underestimating the accuracy of the most uncertain cues. The P2 amplitude was significantly increased during cue presentation when advisors were in disagreement as compared to when all were in agreement, regardless of cue validity. Further, a larger P3 amplitude during outcome presentation was found when advisors were in disagreement and increased with more informative cues. As such, the most uncertain cues were related to the smallest P3 amplitude. The findings hint at the possible role of P3 in judging and learning the predictability of social cues. This study provides novel insights into the role of P2 and P3 components during the judgment of social information validity.

    背景:尽管安全气候,团队合作,手术室中的其他非技术技能可能会影响临床结果,没有显示直接关联,至少部分是由于样本量的考虑。我们报告了麻醉评估的回顾性队列数据,可以简化该领域前瞻性观察研究的设计。麻醉中的非技术技能之间的关联,特别是麻醉师“临床监督质量和护士麻醉师”的工作习惯,并检查了患者和手术因素。
    方法:纳入了一家医院的八个财政年度评估和手术案例。每天使用九项量表评估麻醉医师的临床监督。每天使用六项量表评估护士麻醉师的工作习惯。两组员工的因变量都是二元的,是否所有项目都被给予最高分数。用一整天的患者和操作变量测试相关性。
    结果:受训人员对麻醉师进行了40,718次评估,麻醉师对护士麻醉师的53,772次评估,和296,449起案件,评价者和费率一起开始。对于所有自变量,科恩的d值都很小(≤0.10),提示患者和手术因素之间缺乏任何有临床意义的关联,并在评分最高的情况下进行评估.对于监理质量,骨科病例的日计数是评分的显著预测因子(P=0.0011).然而,由此产生的监督分数等于最大值的绝对边际变化百分比仅为0.8%(99%置信区间:0.2%至1.4%),即,太小,不具有临床或管理重要性。神经外科病例可能是工作习惯的重要预测指标(P=0.0054)。然而,由此产生的工作习惯分数百分比的边际变化等于最大值,增加0.8%(99%置信区间:0.1%至1.6%),这又太小了,不重要。
    结论:在评估分配不同临床表现质量的麻醉医师和麻醉护士对临床结果的影响时,监管质量和工作习惯评分可以作为自变量纳入,而不用担心其效果会与患者或病例特征相关.临床监督和工作习惯是衡量非技术技能的指标。因此,这些发现表明,可以通过观察典型的小样本病例来判断非技术表现。然后,可以使用更多患者的管理数据来测试相关性,因为患者和病例特征与临床医生的非技术表现之间不太可能存在混淆性关联.
    BACKGROUND: Although safety climate, teamwork, and other non-technical skills in operating rooms probably influence clinical outcomes, direct associations have not been shown, at least partially due to sample size considerations. We report data from a retrospective cohort of anesthesia evaluations that can simplify the design of prospective observational studies in this area. Associations between non-technical skills in anesthesia, specifically anesthesiologists\' quality of clinical supervision and nurse anesthetists\' work habits, and patient and operational factors were examined.
    METHODS: Eight fiscal years of evaluations and surgical cases from one hospital were included. Clinical supervision by anesthesiologists was evaluated daily using a nine-item scale. Work habits of nurse anesthetists were evaluated daily using a six-item scale. The dependent variables for both groups of staff were binary, whether all items were given the maximum score or not. Associations were tested with patient and operational variables for the entire day.
    RESULTS: There were 40,718 evaluations of faculty anesthesiologists by trainees, 53,772 evaluations of nurse anesthetists by anesthesiologists, and 296,449 cases that raters and ratees started together. Cohen\'s d values were small (≤0.10) for all independent variables, suggesting a lack of any clinically meaningful association between patient and operational factors and evaluations given the maximum scores. For supervision quality, the day\'s count of orthopedic cases was a significant predictor of scores (P = 0.0011). However, the resulting absolute marginal change in the percentage of supervision scores equal to the maximum was only 0.8% (99% confidence interval: 0.2% to 1.4%), i.e., too small to be of clinical or managerial importance. Neurosurgical cases may have been a significant predictor of work habits (P = 0.0054). However, the resulting marginal change in the percentage of work habits scores equal to the maximum, an increase of 0.8% (99% confidence interval: 0.1% to 1.6%), which was again too small to be important.
    CONCLUSIONS: When evaluating the effect of assigning anesthesiologists and nurse anesthetists with different clinical performance quality on clinical outcomes, supervision quality and work habits scores may be included as independent variables without concern that their effects are confounded by association with the patient or case characteristics. Clinical supervision and work habits are measures of non-technical skills. Hence, these findings suggest that non-technical performance can be judged by observing the typical small sample size of cases. Then, associations can be tested with administrative data for a far greater number of patients because there is unlikely to be a confounding association between patient and case characteristics and the clinicians\' non-technical performance.

    这项研究的目的是调查社会经济地位(SES)和执行功能之间的关系,特别关注性能监控,错误检测,以及它们与中额叶θ和误差相关负性(ERN)的关联。采用广泛使用的侧翼任务,该研究涉及两个阶段,参与者年龄在10-16岁(试验阶段为15人,第二阶段为35人).在各种条件下分析了来自不同大脑区域的脑电图(EEG)记录。研究表明,在侧翼任务期间,Fcz的绝对和相对θ功率均显着增加,在不正确的试验中观察到更强的效果。此外,它强调了社会经济地位(SES)对中额叶θ的影响,突出SES之间的相互作用,性别,和实验条件影响绝对和相对θ。有趣的是,研究表明,父母的职业和错误相关的负性(ERN)之间存在正相关关系,以及年龄和ERN之间。这些发现强调了SES的重要性,性别,以及塑造与表现监控和执行功能相关的神经机制的年龄。这项研究为社会人口因素和认知过程之间的复杂相互作用提供了宝贵的见解,阐明它们对目标导向行为和大脑活动的影响。
    The aim of the study was to investigate the relationship between socioeconomic status (SES) and executive functioning, focusing specifically on performance monitoring, error detection, and their association with mid-frontal theta and error-related negativity (ERN). Employing the widely used flanker task, the research involved two phases with participants aged 10-16 years (15 individuals in the pilot phase and 35 in the second phase). Electroencephalogram (EEG) recordings from distinct brain regions were analyzed during various conditions. The study revealed a notable increase in both absolute and relative theta power at Fcz during the flanker task, with a stronger effect observed during incorrect trials. Furthermore, it underscored the influence of socioeconomic status (SES) on mid-frontal theta, highlighting interactions between SES, gender, and experimental conditions impacting both absolute and relative theta. Intriguingly, the research disclosed a positive correlation between parental occupation and error-related negativity (ERN), as well as between age and ERN. These findings underscore the significance of SES, gender, and age in shaping the neural mechanisms associated with performance monitoring and executive functions. The study contributes valuable insights into the intricate interplay between socio-demographic factors and cognitive processes, shedding light on their impact on goal-directed behaviors and brain activity.

    已经证明,在运动反应过程中,运动皮质区域的激活与内侧额叶皮质的激活密切相关,这与表现监测和认知控制有关。本研究探索了正确和错误响应期间与响应相关的电位的振荡神经动力学,以检验以下假设:这种连续通信会在性能错误期间改变运动电位的特征。在四选择反应任务中,在64个电极上记录了脑电图(EEG),并分析了正确和错误反应的反应相关电位(RRP)。在theta(3.5-7Hz)和delta(1-3Hz)频带中分析了扩展电机区域的振荡RRP分量相对于功率,时间同步(相位锁定因子,PLF),和空间同步(锁相值,PLV).主要结果表明,正确响应和错误响应之间的电动机振荡有所不同。与错误相关的变化(1)是频率特异性的,接合的δ和θ频带,(2)在反应产生之前已经出现,(3)在后感觉运动和前部(运动前和内侧额叶)区域具有特定的区域地形。具体来说,在误差过程中,电机和感觉运动区域与三角网络支持的响应相反的连通性大大降低。此外,在这些区域,对δ和θ振荡的相位稳定性有误差相关的抑制。这种同步减少伴随着双侧运动前区域的运动theta振荡的时间同步增加,以及内侧额叶区域的两个独特的与误差相关的影响:(1)theta功率的聚焦前中央增强和(2)可分离增强具有局部内侧额叶焦点的delta振荡的时间同步。一起,这些观察结果表明,表现错误的电生理特征不限于内侧额叶信号,但它们也涉及到产生运动的扩展皮质区域的振荡运动网络的动力学。此外,它们提供了与错误处理相关的内侧额叶过程的更详细的图片。
    It has been demonstrated that during motor responses, the activation of the motor cortical regions emerges in close association with the activation of the medial frontal cortex implicated with performance monitoring and cognitive control. The present study explored the oscillatory neurodynamics of response-related potentials during correct and error responses to test the hypothesis that such continuous communication would modify the characteristics of motor potentials during performance errors. Electroencephalogram (EEG) was recorded at 64 electrodes in a four-choice reaction task and response-related potentials (RRPs) of correct and error responses were analysed. Oscillatory RRP components at extended motor areas were analysed in the theta (3.5-7 Hz) and delta (1-3 Hz) frequency bands with respect to power, temporal synchronization (phase-locking factor, PLF), and spatial synchronization (phase-locking value, PLV). Major results demonstrated that motor oscillations differed between correct and error responses. Error-related changes (1) were frequency-specific, engaging delta and theta frequency bands, (2) emerged already before response production, and (3) had specific regional topographies at posterior sensorimotor and anterior (premotor and medial frontal) areas. Specifically, the connectedness of motor and sensorimotor areas contra-lateral to the response supported by delta networks was substantially reduced during errors. Also, there was an error-related suppression of the phase stability of delta and theta oscillations at these areas. This synchronization reduction was accompanied by increased temporal synchronization of motor theta oscillations at bi-lateral premotor regions and by two distinctive error-related effects at medial frontal regions: (1) a focused fronto-central enhancement of theta power and (2) a separable enhancement of the temporal synchronization of delta oscillations with a localized medial frontal focus. Together, these observations indicate that the electrophysiological signatures of performance errors are not limited to the medial frontal signals, but they also involve the dynamics of oscillatory motor networks at extended cortical regions generating the movement. Also, they provide a more detailed picture of the medial frontal processes activated in relation to error processing.

    随着30多年前错误引起的事件相关电位的发现,绩效监控研究的新途径,认知控制,决策出现了。从那以后,该领域迅速发展和扩大。在简要概述了性能监测的脑电图相关性之后,本文回顾了基于使用独立成分分析的单次试验分析的最新进展,多元回归,和多元模式分类。鉴于性能监控和强化学习之间的紧密联系,计算建模和基于模型的脑电分析产生了特别强烈的影响。审查的结果表明,与错误和反馈相关的EEG动力学代表变量,这些变量反映了如何对性能监控信号进行加权并将其转换为指导未来决策和行动的适应信号。基于模型的单次试验分析方法远远超出了事件相关电位的常规峰谷分析,并且能够测试性能监测的机械理论,认知控制,和决策。
    With the discovery of event-related potentials elicited by errors more than 30 years ago, a new avenue of research on performance monitoring, cognitive control, and decision making emerged. Since then, the field has developed and expanded fulminantly. After a brief overview on the EEG correlates of performance monitoring, this article reviews recent advancements based on single-trial analyses using independent component analysis, multiple regression, and multivariate pattern classification. Given the close interconnection between performance monitoring and reinforcement learning, computational modeling and model-based EEG analyses have made a particularly strong impact. The reviewed findings demonstrate that error- and feedback-related EEG dynamics represent variables reflecting how performance-monitoring signals are weighted and transformed into an adaptation signal that guides future decisions and actions. The model-based single-trial analysis approach goes far beyond conventional peak-and-trough analyses of event-related potentials and enables testing mechanistic theories of performance monitoring, cognitive control, and decision making.
