    以前的研究表明,像面孔,单词是整体处理的,或者通过自动表示它们的部分组合来处理的。被认为是单词整体处理基础的自动化假设个人对这些过程的控制水平相对较低。然而,他们还可能能够从他们的环境中学习处理单词作为一个整体是否是最有效的处理策略-这将需要对相应的过程进行至少一些控制。事实上,先前的研究在面部整体处理的背景下支持后一种说法:当提供一项任务时,参与者应忽略一半的刺激(无关部分),并选择性地注意另一半(目标部分),参与者在忽略无关紧要的部分时变得更好(即,这表明响应不同于任务上下文中相关部分的响应)。在目前的工作中,我们将这些考虑扩展到整体文字处理。我们的结果支持在整体文字处理的背景下学习的注意力帐户。当不相关的单词部分对目标单词一半的判断有系统的帮助时,参与者更多地参与整体处理(与当无关紧要的词“一半”具有误导性时)。这反映了偶然的统计学习过程,在该过程中,个人将不相关的单词一半识别为提供有关目标一半的有用或误导性信息。
    Previous research has shown that, like faces, words are processed either holistically or through the automatic representation of their parts combined. The automaticity assumed to underlie the holistic processing of words presupposes that individuals have a relatively low level of control over these processes. However, they may also be capable of learning from their environments whether processing words as a whole is the most efficient processing strategy-which would require at least some control over the corresponding processes. In fact, previous research supports this latter account in the context of the holistic processing of faces: when provided a task in which participants should ignore half of a stimuli (the irrelevant part) and pay selective attention to the other half (the target part), the participants become better at ignoring the irrelevant part when it is commonly misleading (i.e., this suggests a response that is different from that of the relevant part in the context of the task). In the present work, we extend these considerations to holistic word processing. Our results support a learned attentional account in the context of holistic word processing. When an irrelevant word part is systematically helpful for the judgment of a target word half, participants engage more in holistic processing (vs. when the irrelevant word half is misleading). This reflects an incidental statistical learning process in which individuals identify the irrelevant word half as either providing helpful or misleading information about the target half.

    在本研究中,我们使用块式(实验1)和试验式(实验2和3)操作来表示奖励的可能性,通过手动响应(实验1和2:Simon和Stroop任务;实验3:Simon和Eriksen侧翼任务),研究了绩效或有奖励前景对任务绩效的影响。在所有实验中,与每个冲突任务中的无奖励条件相比,任务性能(反应时间和/或错误率)通常在奖励方面有所改善。然而,有,如果有的话,很少有证据表明奖励操纵调节了平均冲突效应的大小,并且在通过分布分析(delta图)控制冲突处理中的时变波动时,也没有证据表明奖励的特定冲突效果。因此,结果没有为冲突特定账户提供证据,而是倾向于绩效一般账户,其中奖励预期导致整体性能改进而不影响冲突效应。我们讨论了主动控制如何调节冲突任务中目标处理和干扰处理之间的相互作用的可能含义。
    In the present study, we investigated the influence of performance-contingent reward prospects on task performance across three visual conflict tasks with manual responses (Experiments 1 & 2: Simon and Stroop tasks; Experiment 3: Simon and Eriksen flanker task) using block-wise (Experiment 1) and trial-wise (Experiments 2 & 3) manipulations to signal the possibility of reward. Across all experiments, task performance (in reaction time and/or error rates) generally improved in reward compared with no-reward conditions in each conflict task. However, there was, if any, little evidence that the reward manipulation modulated the size of the mean conflict effects, and there was also no evidence for conflict-specific effects of reward when controlling for time-varying fluctuations in conflict processing via distributional analyses (delta plots). Thus, the results provide no evidence for conflict-specific accounts and instead favor performance-general accounts, where reward anticipation leads to overall performance improvements without affecting conflict effects. We discuss possible implications for how proactive control might modulate the interplay between target- and distractor-processing in conflict tasks.

    体现认知理论表明,手部动作和认知是紧密相连的。一种新兴的跟踪参与者如何移动计算机鼠标的技术(即,鼠标跟踪技术)在检测内隐认知冲突方面比传统的响应时间测量显示出优势。先前的研究表明,注意力对于在语义层面进行下意识处理至关重要。然而,这一假设受到证据的挑战,这些证据表明在几乎没有注意力的情况下存在意识下语义加工。证据的不一致可能源于响应时间测量的灵敏度不足。因此,我们通过使用鼠标跟踪技术分析参与者的手部动作,研究了注意力在意识下语义处理中的作用。结果表明,意识下语义加工不仅可以通过注意力增强,而且在注意力中断时也会发生,挑战促进自上而下关注下意识语义处理的必要性,正如许多研究所声称的那样。此外,通过操纵注意力线索的颜色,我们的实验表明,提示颜色本身可以影响参与者的反应模式。总的来说,目前的研究表明,注意状态和潜意识语义处理可以通过从光标运动轨迹中提取的时空特征来可靠地揭示。
    Theories of embodied cognition suggest that hand motions and cognition are closely interconnected. An emerging technique of tracking how participants move a computer mouse (i.e., the mouse-tracking technique) has shown advantages over the traditional response time measurement to detect implicit cognitive conflicts. Previous research suggests that attention is essential for subliminal processing to take place at a semantic level. However, this assumption is challenged by evidence showing the presence of subliminal semantic processing in the near-absence of attention. The inconsistency of evidence could stem from the insufficient sensitivity in the response time measurement. Therefore, we examined the role of attention in subliminal semantic processing by analyzing participants\' hand motions using the mouse-tracking technique. The results suggest that subliminal semantic processing is not only enhanced by attention but also occurs when attention is disrupted, challenging the necessity of facilitated top-down attention for subliminal semantic processing, as claimed by a number of studies. In addition, by manipulating the color of attentional cues, our experiment shows that the cue color per se could influence participants\' response patterns. Overall, the current study suggests that attentional status and subliminal semantic processing can be reliably revealed by temporal-spatial features extracted from cursor motion trajectories.

    本研究调查了全球行为适应对不同干扰方式引起的冲突的影响。使用具有恒定视觉目标的Eriksen侧翼范例进行了三个实验,而是随机变化的听觉或视觉干扰物。在实验1中,两种干扰方式的一致试验与不一致试验的比例都不同,而在实验2A和2B中,将这种比例一致性(PC)操作应用于使用一种干扰方式(诱导物)的试验,以测试使用另一种干扰方式(诊断)的试验的潜在行为转移效应.在所有的实验中,平均比例一致性效应(PCE)存在于使用PC操作的试验中,但是在实验2A和2B中没有转移到诊断试验的证据。分布分析(delta图)通过在增加全等试验的比率时显示出视觉而非听觉干扰物的delta图的斜率差异,为干扰物模态特定的全局行为适应提供了进一步的证据。因此,有人建议,由于学习特定于模态的记忆痕迹,干扰者模态限制了全局行为适应效应(例如,干扰者-目标关联)和/或特定于模态的认知控制过程(例如,抑制特定于模态的基于干扰物的激活)。此外,其他分析显示,在不同干扰模式的试验中,一致性序列效应部分转移,这表明干扰模式可能对局部和全局行为适应产生不同影响.
    The present study investigated global behavioral adaptation effects to conflict arising from different distractor modalities. Three experiments were conducted using an Eriksen flanker paradigm with constant visual targets, but randomly varying auditory or visual distractors. In Experiment 1, the proportion of congruent to incongruent trials was varied for both distractor modalities, whereas in Experiments 2A and 2B, this proportion congruency (PC) manipulation was applied to trials with one distractor modality (inducer) to test potential behavioral transfer effects to trials with the other distractor modality (diagnostic). In all experiments, mean proportion congruency effects (PCEs) were present in trials with a PC manipulation, but there was no evidence of transfer to diagnostic trials in Experiments 2A and 2B. Distributional analyses (delta plots) provided further evidence for distractor modality-specific global behavioral adaptations by showing differences in the slope of delta plots with visual but not auditory distractors when increasing the ratio of congruent trials. Thus, it is suggested that distractor modalities constrain global behavioral adaptation effects due to the learning of modality-specific memory traces (e.g., distractor-target associations) and/or the modality-specific cognitive control processes (e.g., suppression of modality-specific distractor-based activation). Moreover, additional analyses revealed partial transfer of the congruency sequence effect across trials with different distractor modalities suggesting that distractor modality may differentially affect local and global behavioral adaptations.

    在过去的几十年里,与事件相关的潜在的内在和获得性的处理研究取得了很大的进展,但这两个维度很少同时变化。只有这样,然而,我们可以研究外在效价的获得是否随内在效价而变化,以及内在效价和获得效价是否具有相同的大脑机制。45名参与者进行了得失的联想学习,使用固有价不同的图片(正,负)和结果(90%收益,50%/50%,90%的损失)。记录64通道脑电图。在收购过程中,每个效价/结果组合的一张图片被反复呈现,其次是抽象的结果信息(+10ct,-10ct)以预定义的概率。在测试阶段,参与者按下按钮,以赚取真正的收益,并避免与图片相关的真正损失。这里,对于RT,观察到结果的影响和/或其与内在效价的一致性,错误率,额叶θ功率,后P2、P300和LPP。此外,结果系统地影响了测试后的效价和唤醒等级。在收购过程中,随着学习的进展,对额叶负慢波振幅的偶然效应(90%>50%),独立于结果,价,和一致性。习得过程中相对缺乏结果效应表明“冷”语义,而不是真正对收益和损失进行情感处理。然而,测试阶段的实际收益和损失,“热”情感处理发生,结果及其与内在效价的一致性影响了行为和神经加工。最后,这些数据表明内在和获得性的共同和不同的脑机制.
    During the last decades, event-related potential research on the processing of intrinsic and acquired valence has made great progress, but the two dimensions rarely varied simultaneously. Only that way, however, can we investigate whether the acquisition of extrinsic valence varies with intrinsic valence and whether intrinsic and acquired valence share the same brain mechanisms. Forty-five participants performed associative learning of gains and losses, using pictures varying on intrinsic valence (positive, negative) and outcome (90 % gain, 50 %/50 %, 90 % loss). 64-channel EEG was recorded. During acquisition, one picture from each valence/outcome combination was repeatedly presented, followed by abstract outcome information (+10 ct, -10 ct) at the predefined probability. In the test phase, participants pressed buttons to earn the real gains and avoid the real losses associated with the pictures. Here, effects of outcome and/or its congruence with intrinsic valence were observed for RT, error rate, frontal theta power, posterior P2, P300, and LPP. Moreover, outcome systematically affected post-test valence and arousal ratings. During acquisition, a contingency effect (90 % > 50 %) on amplitude of a frontal negative slow wave accompanied the progress of learning, independently of outcome, valence, and congruence. The relative absence of outcome effects during acquisition suggests \"cold\" semantic rather than genuinely affective processing of gains and losses. However, with real gains and losses in the test phase, \"hot\" affective processing took place, and outcome and its congruence with intrinsic valence influenced behavior and neural processing. Finally, the data suggest both shared and distinct brain mechanisms of intrinsic and acquired valence.

    数字认知提供了一个机会来研究面对冲突时选择性注意数字信息的潜在过程,非数值,不同大小的信息。例如,在数值Stroop范式中,参与者被要求判断成对的阿拉伯数字,其物理大小可以是一致的(例如,3vs.5)或不一致(例如,3vs.5)具有数值性。当确定两个数字中的哪个数字在数字上较大时,一致性效果被认为反映了对无关物理大小的抑制。然而,很少有研究调查不相关的非数字信息的显著性对这些一致性效应及其神经底物的影响。在数字Stroop任务中记录了32名成年人的EEG,具有两个显着性(低,高)的不相关尺寸维度。在行为层面,我们在高显著性条件下观察到了更大的一致性效应(即,当两个数字之间的大小差异较大时)。在神经层面,在中心顶叶电极,我们重复了以前的研究,显示一致性对刺激后280到370ms之间的事件相关电位(ERP)振幅的主要影响,以及刺激后200毫秒左右显著性的主要影响。至关重要的是,一致性和显著性在230和250毫秒(P2)之间相互作用,和290和340毫秒之间(P3)。这些结果为导致一致性效应增加的单独过程提供了支持,这可以归因于对无关维度的抑制的更高要求,以及对相关数字信息的关注。
    Numerical cognition provides an opportunity to study the underlying processes of selective attention to numerical information in the face of conflicting, non-numerical, information of different magnitudes. For instance, in the numerical Stroop paradigm, participants are asked to judge pairs of Arabic digits whose physical size can either be congruent (e.g., 3 vs. 5) or incongruent (e.g., 3 vs. 5) with numerical value. Congruency effects when deciding which of the two digits is numerically larger are thought to reflect the inhibition of the irrelevant physical size. However, few studies have investigated the impact of the salience of the irrelevant non-numerical information on these congruency effects and their neural substrates. EEG was recorded in 32 adults during a numerical Stroop task with two levels of salience (low, high) of the irrelevant size dimension. At the behavioral level, we observed larger congruency effects in the high salience condition (i.e., when the difference in size between the two digits is larger). At the neural level, at centro-parietal electrodes, we replicated previous studies showing a main effect of congruency on event-related potential (ERP) amplitudes between 280 and 370 ms post-stimulus, as well as a main effect of salience around 200 ms post-stimulus. Crucially, congruency and salience interacted both between 230 and 250 ms (P2), and between 290 and 340 ms (P3). These results provide support for separate processes underlying the increase in congruency effect, which can be attributed to higher demands in both the inhibition of the irrelevant dimension, and the attention to the relevant numerical information.

    非数字刺激特征经常影响观察者的数字判断:在判断显示器中的项目数量时,我们通常(错误)认为具有更大累积表面积的集合更多。这些“一致性效应”通常被用作视觉如何提取数字信息的证据,并在围绕非数字线索的争论中被调用(例如,累积面积,密度,等。)结合起来进行数字感知。我们测试了一个这样的线索-累积区域-是否有一致性效应提供了证据,证明它在数字感知中必然被使用和整合,或者它对数字的影响是有延展性的。在实验1中,我们复制并扩展了先前的工作,表明反馈的存在消除了数量和累积面积之间的一致性效应,这表明累积面积在数字感知中的作用是可塑的,而不是强制性的。在实验2中,我们测试了这种可延展的影响是否是由于使用了有关数字自然与累积面积相关的先验经验,或者反应竞争的结果,数量和累积面积积极竞争相同的行为决策。我们保留累积面积作为视觉提示,但通过用相应的印度教-阿拉伯数字替换点数组的一侧来消除数字的响应竞争。独立于是否存在反馈,我们在实验2中没有观察到一致性效应。这些实验表明,累积面积不一定在数字感知中得到整合,也不是对自然主义相关性的合理使用的反映。但相反,累积面积和数量之间的一致性效应是响应竞争的结果。我们的发现有助于阐明非数字线索和数字相互作用的机制,并解释为什么在研究中有时只观察到一致性效应。
    Non-numeric stimulus features frequently influence observers\' number judgments: when judging the number of items in a display, we will often (mis)perceive the set with a larger cumulative surface area as more numerous. These \"congruency effects\" are often used as evidence for how vision extracts numeric information and have been invoked in arguments surrounding whether non-numeric cues (e.g., cumulative area, density, etc.) are combined for number perception. We test whether congruency effects for one such cue - cumulative area - provide evidence that it is necessarily used and integrated in number perception, or if its influence on number is malleable. In Experiment 1, we replicate and extend prior work showing that the presence of feedback eliminates congruency effects between number and cumulative area, suggesting that the role of cumulative area in number perception is malleable rather than obligatory. In Experiment 2, we test whether this malleable influence is because of use of prior experiences about how number naturalistically correlates with cumulative area, or the result of response competition, with number and cumulative area actively competing for the same behavioral decision. We preserve cumulative area as a visual cue but eliminate response competition with number by replacing one side of the dot array with its corresponding Hindu-Arabic numeral. Independent of the presence or absence of feedback, we do not observe congruency effects in Experiment 2. These experiments suggest that cumulative area is not necessarily integrated in number perception nor a reflection of a rational use of naturalistic correlations, but rather congruency effects between cumulative area and number emerge as a consequence of response competition. Our findings help to elucidate the mechanism through which non-numeric cues and number interact, and provide an explanation for why congruency effects are only sometimes observed across studies.

    Stereotypes facilitate the processing of expectancy-consistent (vs expectancy-inconsistent) information, yet the underlying origin of this congruency effect remains unknown. As such, here we sought to identify the cognitive operations through which stereotypes influence decisional processing. In six experiments, participants responded to stimuli that were consistent or inconsistent with respect to prevailing gender stereotypes. To identify the processes underpinning task performance, responses were submitted to a hierarchical drift diffusion model (HDDM) analysis. A consistent pattern of results emerged. Whether manipulated at the level of occupational (Expts. 1, 3, and 5) or trait-based (Expts. 2, 4, and 6) expectancies, stereotypes facilitated task performance and influenced decisional processing via a combination of response and stimulus biases. Specifically, (1) stereotype-consistent stimuli were classified more rapidly than stereotype-inconsistent stimuli; (2) stereotypic responses were favoured over counter-stereotypic responses (i.e., starting-point shift towards stereotypic responses); (3) less evidence was required when responding to stereotypic than counter-stereotypic stimuli (i.e., narrower threshold separation for stereotypic stimuli); and (4) decisional evidence was accumulated more efficiently for stereotype-inconsistent than stereotype-consistent stimuli and when targets had a typical than atypical facial appearance. Collectively, these findings elucidate how stereotypes influence person construal.

    Mindfulness is frequently associated with improved attention. However, the nature of the relationship between mindfulness and executive attention, a core function of the attentional system, is surprisingly unclear. Studies employing behavioral measures of executive attention have been equivocal. Although neuroscientific studies have yielded more consistent findings, reporting functional and structural changes in executive attention brain regions, the observed changes in brain activity have not been linked to behavioral performance. The current study aimed to fill these gaps in the literature by examining the extent to which trait mindfulness related to behavioral and neurophysiological (indexed by the stimulus-locked P3) measures of executive attention. Results revealed that higher trait mindfulness was related to less flanker interference on accuracy and reaction time, consistent with enhanced executive attention. Critically, mediational analyses showed that the P3 accounted for the relationship between trait mindfulness and executive attention performance, elucidating a neural mechanism through which mindfulness enhances executive attention.

    Response-congruency effects in task switching are the observed slowing of response times (RTs) for incongruent targets which afford more than one response (depending on task) in comparison to congruent stimuli that afford just one response regardless of the task. These effects are thought to reflect increased ambiguity during response selection for incongruent stimuli.
    The present study presents a meta-analysis of 27 conditions (from 16 separate studies) whose designs allowed investigation of age-related differences in response-congruency effects on RT.
    Multilevel modelling of Brinley plots and state-trace plots showed no age-related effect on response congruency beyond that which can be explained by general age-related slowing.
    The results add to the growing body of evidence of no age-related decline in measures of attention and executive functioning.
