Humans can rapidly and accurately extract statistical information about features of the visual environment, an ability referred to as ensemble perception. However, little is known about how ensemble estimates are affected when task-irrelevant and distracting feature information is present. Here, we tested how effectively feature-based attention-when tuned to a specific color-can select a single item set out of two intermixed ensembles of colored lines. Participants were instructed to report the average orientation of a target-colored item set, while ignoring a second differently colored set. To assess how representational overlap between the two sets impacts color-based selection, we systematically varied the orientation similarity between the relevant and irrelevant items. Our results showed that participants' orientation reports were reliably biased towards the irrelevant items, but interestingly, these biases were only observed when the item sets overlapped in orientation space. In a second experiment, using a visual mask to disrupt access to color information at different time points, we found that these biases were stronger when less time was available to process the stimuli. Together, these results suggest that ensemble representations are rapidly formed based on all available information in the relevant feature dimension, regardless of task relevance, and that selective attention weights and separates these ensemble representations at a relatively later processing stage. This selection appears highly effective when the underlying population activity generated by the two sets is separable along the to-be-estimated feature dimension, but is dampened when relevant and irrelevant ensemble representations overlap in feature space.

人类可以快速、准确地提取视觉环境特征的统计信息,这种能力被称为集合感知。然而,当出现与任务无关和干扰性的特征信息时,集合估计会受到怎样的影响却鲜为人知。在这里,我们测试了基于特征的注意力(当调整到特定颜色时)如何有效地从两个混合的彩色线条集合中选择单个项目集。参与者被要求报告目标颜色项目集的平均方向,同时忽略第二个不同颜色的项目集。为了评估两组项目之间的表象重叠对基于颜色的选择有何影响,我们系统地改变了相关项目和无关项目之间的方向相似性。我们的结果表明,参与者的方位报告明显偏向无关项目,但有趣的是,只有当项目集在方位空间中重叠时才会出现这种偏差。在第二项实验中,我们使用了视觉遮罩来中断不同时间点对颜色信息的访问,结果发现,当可用来处理刺激的时间较短时,这些偏差会更强。总之,这些结果表明,集合表征是根据相关特征维度的所有可用信息迅速形成的,与任务的相关性无关,而选择性注意会在相对较晚的处理阶段对这些集合表征进行加权和分离。当两组刺激产生的潜在群体活动沿着待估计的特征维度可分离时,这种选择似乎非常有效,但当相关和不相关的集合表征在特征空间重叠时,这种选择就会受到抑制。

The current study investigated whether word integration follows a strictly sequential order during natural Chinese reading. Chinese readers' eye movements were recorded when they read sentences containing a three-character string (ABC), where BC was always a two-character word and AB was also a two-character word in the overlapping condition but not a word in the non-overlapping condition. We manipulated the extent to which word BC was plausible as an immediate continuation following prior context (cross-word plausibility); the string AB was always implausible given the prior context, and the sentence continued in a manner that was compatible with A-BC. The results showed that there were longer second-pass reading times on the string ABC region in the cross-word plausible condition than those in the cross-word implausible condition in both the overlapping condition and the non-overlapping condition. These results imply that readers do not always integrate words strictly in the order in which they appear in Chinese reading.

本研究探讨了在中文自然阅读过程中,词的整合是否遵循严格的顺序。我们记录了中文读者在阅读包含三字符串(ABC)的句子时的眼动情况,其中 BC 总是两个字符的词,AB 在重叠条件下也是两个字符的词,但在非重叠条件下不是一个词。我们操纵了单词 BC 在多大程度上可以作为先前语境后的直接延续(交叉单词可信度);考虑到先前语境,字符串 AB 始终是不可信的,句子以与 A-BC 相符的方式继续。结果显示,在重叠条件和非重叠条件下,交叉词可信条件下的 ABC 字符串区域的二次阅读时间都比交叉词不可信条件下的时间长。这些结果表明,在中文阅读中,读者并不总是严格按照词语出现的顺序进行整合。

Signal detection theory (SDT) has long provided the field of psychology with a simple but powerful model of how observers make decisions under uncertainty. SDT can distinguish sensitivity from response bias and characterize optimal decision strategies. Whereas classical SDT pertains to "type 1" judgments about the world, recent work has extended SDT to quantify sensitivity for metacognitive or "type 2" judgments about one's own type 1 processing, e.g. confidence ratings. Here we further advance the application of SDT to the study of metacognition by providing a formal account of normative metacognitive decision strategies - i.e., type 2 (confidence) criterion setting - for ideal observers. Optimality is always defined relative to a given objective. We use SDT to derive formulae for optimal type 2 criteria under four distinct objectives: maximizing type 2 accuracy, maximizing type 2 reward, calibrating confidence to accuracy, and maximizing the difference between type 2 hit rate and false alarm rate. Where applicable, we consider these optimization contexts alongside their type 1 counterparts (e.g. maximizing type 1 accuracy) to deepen understanding. We examine the different strategies implied by these formulae and further consider how optimal type 2 criterion setting differs when metacognitive sensitivity deviates from SDT expectation. The theoretical framework provided here can be used to better understand the metacognitive decision strategies of real observers. Possible applications include characterizing observers' spontaneously chosen metacognitive decision strategies, assessing their ability to fine-tune metacognitive decision strategies to optimize a given outcome when instructed, determining over- or under-confidence relative to an optimal standard, and more. This framework opens new avenues for enriching our understanding of metacognition.

长期以来,信号检测理论(SDT)为心理学领域提供了一个简单而强大的模型,说明观察者如何在不确定情况下做出决策。SDT 可以区分敏感性和反应偏差,并描述最佳决策策略。经典的 SDT 与对世界的 "第一类 "判断有关,而最近的研究则将 SDT 扩展到了量化元认知或 "第二类 "判断的敏感性,即对自身第一类过程的判断,例如置信度评级。在这里,我们通过对理想观察者的规范性元认知决策策略(即第二类(置信度)标准设定)进行正式说明,进一步推动了 SDT 在元认知研究中的应用。最优性总是相对于给定目标而定义的。我们使用 SDT 来推导出四个不同目标下的最佳第二类标准公式:第二类准确性最大化、第二类奖励最大化、信心与准确性校准、第二类命中率与误报率之差最大化。在适用的情况下,我们将这些优化环境与第一类环境(如第一类准确率最大化)一并考虑,以加深理解。我们研究了这些公式所隐含的不同策略,并进一步考虑了当元认知敏感性偏离 SDT 预期时,最佳类型 2 标准设置有何不同。本文提供的理论框架可用于更好地理解真实观察者的元认知决策策略。可能的应用包括描述观察者自发选择的元认知决策策略的特征,评估观察者微调元认知决策策略的能力,以便在接受指导时优化给定结果,确定相对于最优标准的过度自信或不足自信,等等。这一框架为丰富我们对元认知的理解开辟了新的途径。

The self-relevant spotlight metaphor: Self-relevant targets diminish distractor-response-binding effects. 与自身相关的聚光灯隐喻:与自身相关的目标会削弱分心者的反应束缚效应。

Recently, it has been proposed that self-relevance of a stimulus enhances executive control and reduces the impact of distractors on current task performance. The present study aimed to test whether the binding between a distractor and a response is influenced by self-relevance, too. We assumed that targets' self-relevance should increase executive control processes and therefore reduce the influence of distractors on current performance. In a distractor-response-binding (DRB) task, which measures the strength of binding between distractor stimuli and responses, we varied target relevance so that participants responded to targets that either were or were not self-relevant. Our design made it possible to measure DRB effects for both relevance conditions separately. DRB effects were diminished if targets were self-relevant compared to when they were not. These results expand our understanding of the influence of self-relevance on cognitive performance. The influence of self-relevance is not purely perceptual (Sui & Humphreys, 2012, Journal of Experimental Psychology: Human Perception and Performance, 38[5], 1105-1117), but also found in higher-order processes such as executive control. Moreover, whereas for different paradigms binding advantages of self-relevance are assumed (Sui & Humphreys, 2015a, Trends in Cognitive Sciences, 19[12], 719-728; Humphreys & Sui, 2016, Cognitive Neuroscience, 7[1/4], 5-17), this study identifies an important boundary condition, in that distractor-response binding is reduced by target self-relevance.

最近有人提出,刺激物的自我相关性会增强执行控制,减少分心物对当前任务表现的影响。本研究旨在测试分心物与反应之间的结合是否也受自我相关性的影响。我们假设,目标的自我相关性应该会增强执行控制过程,从而减少分心物对当前表现的影响。分心-反应-结合(DRB)任务测量的是分心刺激与反应之间的结合强度,在这项任务中,我们改变了目标的相关性,使参与者对自我相关或不相关的目标做出反应。我们的设计使我们能够分别测量两种相关条件下的 DRB 效果。与不相关的目标相比,如果目标与自身相关,DRB效应就会减弱。这些结果拓展了我们对自我相关性对认知表现影响的理解。自我相关性的影响并不纯粹是知觉性的(Sui 和 Humphreys,2012,《实验心理学杂志:人类知觉与表现》,38[5], 1105-1117),它还存在于执行控制等高阶过程中。此外,虽然不同范式都假定自我相关性具有约束力优势(Sui & Humphreys,2015a,Trends in Cognitive Sciences,19[12],719-728;Humphreys & Sui,2016,Cognitive Neuroscience,7[1/4],5-17),但本研究确定了一个重要的边界条件,即目标自我相关性会降低分心者与反应的约束力。

To adapt to an uncertain world, humans must learn event probabilities. These probabilities may be stationary, such as that of rolling a 6 on a die, or changing over time, like the probability of rainfall over the year. Research on how people estimate and track changing probabilities has recently reopened an old epistemological issue. A small, mostly recent literature finds that people accurately track the probability and change their estimates only occasionally, resulting in staircase-shaped response patterns. This has been taken as evidence that people entertain beliefs about unknown, distal states of the world, which are tested against observations to produce discrete shifts between hypotheses. That idea stands in contrast to the claim that people learn by continuously updating associations between observed events. The purpose of this article is to investigate the generality and robustness of the accurate, staircase-shaped pattern. In two experiments, we find that the response pattern is contingent on the response mode and prior information about the generative process. Participants exist on continua of accuracy and staircase-ness and we only reproduce previous results when changing estimates is effortful and prior information is provided-the specific conditions of previous experiments. We conclude that explaining this solely through either hypotheses or associations is untenable. A complete theory of probability estimation requires the interaction of three components: (i) online tracking of observed data, (ii) beliefs about the unobserved "generative process," and (iii) a response updating process. Participants' overt estimates depend on how the specific task conditions jointly determine all three.

为了适应不确定的世界,人类必须学习事件概率。这些概率可能是静态的,比如掷骰子掷出 6 的概率,也可能是随时间变化的,比如一年中降雨的概率。关于人们如何估计和跟踪不断变化的概率的研究,最近重新提出了一个古老的认识论问题。少量的、大多是最新的文献发现,人们准确地跟踪概率,只是偶尔改变他们的估计,从而形成阶梯状的反应模式。这被认为是人们对未知的、遥远的世界状态抱有信念的证据,这些信念通过观察得到检验,从而产生假设之间的离散变化。这一观点与人们通过不断更新观察到的事件之间的关联来学习的说法形成了鲜明对比。本文旨在研究准确的阶梯模式的普遍性和稳健性。在两个实验中,我们发现反应模式取决于反应模式和关于生成过程的先验信息。参与者在准确性和阶梯性上存在连续性,而我们只有在改变估计值需要付出努力和提供先验信息的情况下--也就是之前实验的特定条件下--才会重现之前的结果。我们的结论是,仅仅通过假设或联想来解释这一点是站不住脚的。完整的概率估计理论需要三个组成部分的相互作用:(i) 对观察数据的在线跟踪,(ii) 对未观察到的 "生成过程 "的信念,以及 (iii) 反应更新过程。参与者的公开估计取决于具体任务条件如何共同决定这三个部分。

Simple Recurrent Networks are Interactive. 简单循环网络具有交互性。

There is disagreement among cognitive scientists as to whether a key computational framework - the Simple Recurrent Network (SRN; Elman, Machine Learning, 7(2), 195-225, 1991; Elman, Cognitive Science, 14(2), 179-211, 1990) - is a feedforward system. SRNs have been essential tools in advancing theories of learning, development, and processing in cognitive science for more than three decades. If SRNs were feedforward systems, there would be pervasive theoretical implications: Anything an SRN can do would therefore be explainable without interaction (feedback). However, despite claims that SRNs (and by extension recurrent neural networks more generally) are feedforward (Norris, 1993), this is not the case. Feedforward networks by definition are acyclic graphs - they contain no loops. SRNs contain loops - from hidden units back to hidden units with a time delay - and are therefore cyclic graphs. As we demonstrate, they are interactive in the sense normally implied for networks with feedback connections between layers: In an SRN, bottom-up inputs are inextricably mixed with previous model-internal computations. Inputs are transmitted to hidden units by multiplying them by input-to-hidden weights. However, hidden units simultaneously receive their own previous activations as input via hidden-to-hidden connections with a one-step time delay (typically via context units). These are added to the input-to-hidden values, and the sums are transformed by an activation function. Thus, bottom-up inputs are mixed with the products of potentially many preceding transformations of inputs and model-internal states. We discuss theoretical implications through a key example from psycholinguistics where the status of SRNs as feedforward or interactive has crucial ramifications.

认知科学家对一个关键的计算框架--简单递归网络(SRN;Elman,《机器学习》,7(2), 195-225, 1991 年;Elman,《认知科学》,14(2), 179-211, 1990 年)--是否是前馈系统存在分歧。30 多年来,SRN 一直是推动认知科学学习、发展和处理理论的重要工具。如果 SRN 是前馈系统,就会产生广泛的理论影响:因此,SRN 的任何行为都可以在没有互动(反馈)的情况下得到解释。然而,尽管有人声称 SRN(推而广之是递归神经网络)是前馈的(Norris,1993 年),但事实并非如此。根据定义,前馈网络是非循环图--它们不包含回路。递归神经网络包含循环--从隐藏单元回到隐藏单元,有时间延迟--因此是循环图。正如我们所演示的,它们是交互式的,这通常是指层与层之间有反馈连接的网络:在 SRN 中,自下而上的输入与之前的模型内部计算密不可分。输入通过乘以输入-隐藏权重传递给隐藏单元。然而,隐单元同时也会通过具有一步时间延迟的隐-隐连接(通常是通过上下文单元)接收自己之前的激活作为输入。这些值与输入到隐藏的值相加,然后通过激活函数对总和进行转换。因此,自下而上的输入与之前可能多次输入转化和模型内部状态的乘积混合在一起。我们将通过心理语言学中的一个关键实例来讨论其理论意义,SRN 的前馈或互动地位在其中具有至关重要的影响。

One of the most common statistical analyses in experimental psychology concerns the comparison of two means using the frequentist t test. However, frequentist t tests do not quantify evidence and require various assumption tests. Recently, popularized Bayesian t tests do quantify evidence, but these were developed for scenarios where the two populations are assumed to have the same variance. As an alternative to both methods, we outline a comprehensive t test framework based on Bayesian model averaging. This new t test framework simultaneously takes into account models that assume equal and unequal variances, and models that use t-likelihoods to improve robustness to outliers. The resulting inference is based on a weighted average across the entire model ensemble, with higher weights assigned to models that predicted the observed data well. This new t test framework provides an integrated approach to assumption checks and inference by applying a series of pertinent models to the data simultaneously rather than sequentially. The integrated Bayesian model-averaged t tests achieve robustness without having to commit to a single model following a series of assumption checks. To facilitate practical applications, we provide user-friendly implementations in JASP and via the RoBTT package in R . A tutorial video is available at https://www.youtube.com/watch?v=EcuzGTIcorQ.

实验心理学中最常见的统计分析之一是使用频数 t 检验比较两个均值。然而,频数 t 检验不能量化证据,需要进行各种假设检验。最近流行的贝叶斯 t 检验确实可以量化证据,但这些检验是针对假设两个群体具有相同方差的情况而开发的。作为这两种方法的替代方案,我们概述了一个基于贝叶斯模型平均的综合 t 检验框架。这个新的 t 检验框架同时考虑了假设方差相等和不相等的模型,以及使用 t 概率来提高对异常值的稳健性的模型。由此得出的推论基于整个模型集合的加权平均值,对观测数据预测较好的模型赋予较高权重。这种新的 t 检验框架通过对数据同时而不是按顺序应用一系列相关模型,为假设检查和推断提供了一种综合方法。综合贝叶斯模型平均 t 检验具有稳健性,无需在进行一系列假设检查后再对单一模型做出承诺。为了便于实际应用,我们在 JASP 中提供了用户友好的实现方法,并通过 R 中的 RoBTT 软件包提供了实现方法。教程视频请访问 https://www.youtube.com/watch?v=EcuzGTIcorQ。

Important insights in visual word recognition have been provided by studies examining the combined influence of multiple factors on participants' mean response times to English words in the lexical decision task. However, to make progress towards a complete understanding of how meaning is activated by print, researchers need to conduct more detailed analyses of behavioral patterns beyond mean response latencies and accuracies, particularly how variables influence different components of response time distributions. Moreover, it is critical to extend patterns found in English to the diverse scripts encountered by readers across the world. The present study is the first to explore the theoretically important effects of stimulus quality and word frequency on lexical decisions involving two-character Mandarin Chinese and Cantonese Chinese words, using participants from Singapore and Hong Kong, respectively. Despite the profound differences between the English and Chinese writing systems, we observed remarkably similar trade-offs in the stimulus quality × word frequency interaction across different portions of the response time distribution for both orthographies, indicating that the optimization of lexical processing by leveraging available codes in response to task demands extends across multiple and highly diverse writing systems.

通过研究多种因素对参与者在词性判断任务中对英语单词的平均反应时间的综合影响,人们对视觉单词识别有了重要的认识。然而,要想在全面了解印刷品如何激活意义方面取得进展,研究人员需要对平均反应潜伏期和准确率之外的行为模式进行更详细的分析,特别是变量如何影响反应时间分布的不同组成部分。此外,将在英语中发现的模式扩展到世界各地读者所接触的各种文字也至关重要。本研究首次使用分别来自新加坡和香港的受试者,探讨了刺激质量和词频对涉及双字符普通话和广东话词汇决策的重要理论影响。尽管中英文书写系统差异巨大,但我们观察到在两种正字法的反应时间分布的不同部分,刺激质量与词频交互作用的权衡非常相似,这表明通过利用可用代码来应对任务需求从而优化词法处理的做法适用于多种高度多样化的书写系统。

Not just social networks: How people infer relations from mutual connections. 不仅仅是社交网络:人们如何从相互联系中推断关系

People can infer relationships from incomplete information about social networks. We examined whether these inferences depend on domain-specific knowledge about social relationships or instead depend on domain-general statistical reasoning. In five preregistered experiments, participants (total N = 1,424) saw two target entities and their connections to others in social, semisocial, and nonsocial networks. In Experiments 1 and 2, participants made similar judgments across social and nonsocial networks: with greater proportion of mutual connections and number of connections, the two entities were judged as more likely to be connected to each other. These findings support the domain-general account. The next experiments provided further support for this account, while also investigating the question of whether people use mutual connections to infer the broader structure of networks. In Experiments 3 and 4, participants were asked whether entities connected to both targets were connected to each other, and judgments were hardly affected by network information. In Experiment 5, participants judged connections were more likely when entities were connected to both targets rather than when they were connected to only one. Overall, the findings support the domain-general account of network inferences and further suggest that participants' inferences primarily concerned target entities and not the broader structure of the network.

人们可以从社交网络的不完整信息中推断出各种关系。我们研究了这些推断是依赖于特定领域的社会关系知识,还是依赖于一般领域的统计推理。在五个预先注册的实验中,参与者(总人数 = 1,424)看到了两个目标实体及其在社交、半社交和非社交网络中与他人的联系。在实验 1 和 2 中,参与者在社交网络和非社交网络中做出了相似的判断:相互连接的比例和连接的数量越大,这两个实体被判断为更有可能相互连接。这些发现支持了领域一般解释。接下来的实验进一步支持了这一观点,同时还研究了人们是否利用相互连接来推断更广泛的网络结构这一问题。在实验 3 和实验 4 中,参与者被问及与两个目标相连的实体是否相互连接,他们的判断几乎不受网络信息的影响。在实验 5 中,当实体同时与两个目标相连时,被试判断相互连接的可能性更大,而当实体只与一个目标相连时,被试判断相互连接的可能性更小。总之,实验结果支持网络推断的领域一般解释,并进一步表明参与者的推断主要涉及目标实体,而不是更广泛的网络结构。

Visual statistical learning requires attention. 视觉统计学习需要注意力。

Statistical learning is a person's ability to automatically learn environmental regularities through passive exposure. Since the earliest studies of statistical learning in infants, it has been debated exactly how "passive" this learning can be (i.e., whether attention is needed for learning to occur). In Experiment 1 of the current study, participants performed a serial feature search task where they searched for a target shape among heterogenous nontarget shapes. Unbeknownst to the participants, one of these nontarget shapes was presented much more often in location. Even though the regularity concerned a nonsalient, nontarget item that did not receive any attentional priority during search, participants still learned its regularity (responding faster when it was presented at this high-probability location). While this may suggest that not much, if any, attention is needed for learning to occur, follow-up experiments showed that if an attentional strategy (i.e., color subset search or exogenous cueing) effectively prevents attention from being directed to this critical regularity, incidental learning is no longer observed. We conclude that some degree of attention to a regularity is needed for visual statistical learning to occur.

统计学习是指一个人通过被动接触而自动学习环境规律的能力。自最早对婴儿进行统计学习研究以来,人们一直在争论这种学习到底有多 "被动"(即学习是否需要注意力)。在本次研究的实验 1 中,参与者进行了一项序列特征搜索任务,即在异质的非目标形状中寻找目标形状。在参与者不知道的情况下,其中一个非目标形状出现的频率要高得多。尽管这种规律性涉及到的是一个在搜索过程中没有得到任何注意优先权的非显著性非目标项目,但参与者仍然学会了它的规律性(当它出现在这个高概率位置时,参与者的反应更快)。虽然这可能表明学习的发生并不需要太多的注意(如果有的话),但后续实验表明,如果一种注意策略(即颜色子集搜索或外源提示)有效地阻止了注意指向这一关键的规律性,那么偶然学习就不会再被观察到。我们的结论是,视觉统计学习的发生需要一定程度的对规律性的注意。
