Difficulties in global face processing have been associated with autism. However, autism is heterogenous, and it is not known which dimensions of autistic traits are implicated in face-processing difficulties. To address this gap in knowledge, we conducted two experiments to examine how identification of Mooney face stimuli (stylized, black-and-white images of faces without details) related to the six subscales of the Comprehensive Autistic Trait Inventory in young adults. In Experiment 1, regression analyses indicated that participants with poorer communication skills had lower task sensitivity when discriminating between face-present and face-absent images, whilst other autistic traits had no unique predictive value. Experiment 2 replicated these findings and additionally showed that autistic traits were linked to a reduced face inversion effect. Taken together, these results indicate autistic traits, especially communication difficulties, are associated with reduced configural processing of face stimuli. It follows that both reduced sensitivity for identifying upright faces amongst similar-looking distractors and reduced susceptibility to face inversion effects may be linked to relatively decreased reliance on configural processing of faces in autism. This study also reinforces the need to consider the different facets of autism independently.

自闭症患者在面孔整体处理方面存在困难。然而,自闭症的表现多种多样,目前还不清楚自闭症的哪些特征与人脸处理障碍有关。为了填补这一知识空白,我们进行了两项实验,以研究识别穆尼人脸刺激(无细节的风格化黑白人脸图像)与青壮年自闭症综合特质量表的六个分量表之间的关系。在实验 1 中,回归分析表明,沟通能力较差的参与者在分辨人脸出现和人脸消失的图像时,任务敏感度较低,而其他自闭症特质则没有独特的预测价值。实验 2 复制了这些结果,并显示自闭症特征与脸部反转效应的降低有关。综上所述,这些结果表明,自闭症特质,尤其是沟通障碍,与人脸刺激的构型处理能力降低有关。因此,自闭症患者在相似面孔的干扰物中识别直立面孔的敏感性降低,以及对面孔倒置效应的易感性降低,都可能与自闭症患者对面孔构型加工的依赖性相对降低有关。这项研究还进一步说明,有必要将自闭症的不同表现形式分开考虑。

Peripheral vision is limited due to several factors, such as visual resolution, crowding, and attention. When attention is not directed towards a stimulus, detection, discrimination, and identification are often compromised. Recent studies have found a new phenomenon that strongly limits peripheral vision, “redundancy masking”. In redundancy masking, the number of perceived items in repeating patterns is reduced. For example, when presenting three lines in the peripheral visual field and asking participants to report the number of lines, often only two lines are reported. Here, we investigated what role attention plays in redundancy masking. If redundancy masking was due to limited attention to the target, it should be stronger when less attention is allocated to the target, and absent when attention is maximally focused on the target. Participants were presented with line arrays and reported the number of lines in three cueing conditions (i.e., single cue, double cue, and no cue). Redundancy masking was observed in all cueing conditions, with observers reporting fewer lines than presented in the single, double, and no cue conditions. These results suggest that redundancy masking is not due to limited attention. The number of lines reported was closer to the correct number of lines in the single compared to the double and the no cue conditions, suggesting that reduced attention additionally compromised stimulus discrimination, and replicating typical effects of diminished attention. Taken together, our results suggest that the extent of attention to peripherally presented stimuli modulates discrimination performance, but does not account for redundancy masking.

由于视觉分辨率、拥挤程度和注意力等多种因素,周边视觉受到限制。当注意力不集中在刺激物上时,探测、辨别和识别能力往往会受到影响。最近的研究发现了一种严重限制周边视觉的新现象,即 "冗余遮蔽"。在冗余遮蔽中,重复模式中的感知项目数量会减少。例如,当在外围视野中出现三条线并要求参与者报告线的数量时,往往只能报告出两条线。在此,我们研究了注意力在冗余掩蔽中的作用。如果冗余掩蔽是由于对目标的注意力有限造成的,那么当注意力较少分配到目标上时,冗余掩蔽应该更强,而当注意力最大限度地集中在目标上时,冗余掩蔽应该消失。在三种提示条件下(即单提示、双提示和无提示),向受试者展示线阵列并报告线的数量。在所有提示条件下都观察到了冗余掩蔽,观察者报告的线条数少于在单提示、双提示和无提示条件下呈现的线条数。这些结果表明,冗余掩蔽并不是由于注意力有限造成的。与双线索和无线索条件相比,单线索条件下观察者报告的线条数更接近于正确的线条数,这表明注意力的降低会额外影响刺激辨别能力,并复制了注意力降低的典型效应。总之,我们的研究结果表明,对外围刺激的注意程度会调节辨别能力,但不会导致冗余掩蔽。

Auditory cues are integrated with vision and body-based self-motion cues for motion perception, balance, and gait, though limited research has evaluated their effectiveness for navigation. Here, we tested whether an auditory cue co-localized with a visual target could improve spatial updating in a virtual reality homing task. Participants navigated a triangular homing task with and without an easily localizable spatial audio signal co-located with the home location. The main outcome was unsigned angular error, defined as the absolute value of the difference between the participant’s turning response and the correct response towards the home location. Angular error was significantly reduced in the presence of spatial sound compared to a head-fixed identical auditory signal. Participants’ angular error was 22.79° in the presence of spatial audio and 30.09° in its absence. Those with the worst performance in the absence of spatial sound demonstrated the greatest improvement with the added sound cue. These results suggest that auditory cues may benefit navigation, particularly for those who demonstrated the highest level of spatial updating error in the absence of spatial sound.

在运动感知、平衡和步态方面,听觉线索与视觉和基于身体的自我运动线索相结合,但对其导航效果的评估研究有限。在此,我们测试了听觉线索与视觉目标共同定位是否能改善虚拟现实归位任务中的空间更新。在有和没有与原点位置共同定位的易定位空间音频信号的情况下,受试者进行了三角归位任务导航。主要结果是无符号角度误差,即参与者转向原点的反应与正确反应之间差值的绝对值。与头部固定的相同听觉信号相比,在有空间声音的情况下,角度误差明显减少。在有空间声音的情况下,参与者的角度误差为 22.79°,而在没有空间声音的情况下为 30.09°。那些在没有空间声音时表现最差的人,在添加了声音提示后表现出了最大的改善。这些结果表明,听觉提示可能有利于导航,尤其是那些在没有空间声音时空间更新误差最大的人。

New task–new results? How the gaze cone is influenced by the method of measurement 新任务-新结果?凝视锥如何受到测量方法的影响。

Perceiving direct gaze — the perception of being looked at — is important in everyday life. The gaze cone is a concept to define the area in which observers perceive gaze as direct. The most frequently used methods to measure direct gaze threshold fall into two broad groups: First, a variant of the method of constant stimuli, firstly introduced by Gibson and Pick (The American Journal of Psychology, 76, 386–394, 1963). Second, a variant of the method of adjustment, firstly introduced by Gamer and Hecht (Journal of Experimental Psychology: Human Perception and Performance, 33, 705–715, 2007). Previous studies found a considerable range of thresholds, and although some influences on thresholds are already known (uncertainty, clinical groups), thresholds often vary for no apparent reason. Another important method is a triadic gaze-perception task, which usually finds triadic gaze direction judgments to be overestimated. In two experiments, we compare the method of adjustment with the method of constant stimuli. Experiment 1 additionally examines the influence of the overestimation effect found in the triadic task. Results indicate that thresholds are larger when measured by the method of adjustment than by constant stimuli. Furthermore, Experiment 1 finds a nonlinear overestimation factor, indicating that gaze directions near 0° are less overestimated than larger eccentricities. Correcting the thresholds with individually obtained overestimation factors widens the gaze cone but does not eliminate the average difference between the methods of adjustments and constant stimuli.

感知直接注视--被注视的感觉--在日常生活中非常重要。凝视锥是一个概念,用来定义观察者认为被直接凝视的区域。测量直接注视阈值最常用的方法分为两大类:第一类是恒定刺激法的变体,由 Gibson 和 Pick 首先提出(《美国心理学杂志》,76,386-394,1963 年)。第二,调整法的变体,首先由 Gamer 和 Hecht 提出(《实验心理学杂志:人类感知与表现》,33,705-715,2007 年)。以往的研究发现,阈值的范围相当大,虽然已经知道阈值的一些影响因素(不确定性、临床群体),但阈值经常会无缘无故地发生变化。另一种重要的方法是三元注视感知任务,该方法通常会发现三元注视方向判断被高估。在两个实验中,我们比较了调整法和恒定刺激法。实验 1 还考察了三元任务中发现的高估效应的影响。结果表明,用调整法测量的阈值比用恒定刺激测量的阈值要大。此外,实验 1 还发现了一个非线性高估因子,表明 0°附近的注视方向比较大偏心率的注视方向被高估的程度要低。用单独获得的高估因子对阈值进行校正,可以扩大凝视锥,但并不能消除调整方法和恒定刺激之间的平均差异。

While it is widely accepted that the single gaze of another person elicits shifts of attention, there is limited work on the effects of multiple gazes on attention, despite real-world social cues often occurring in groups. Further, less is known regarding the role of unequal reliability of varying social and nonsocial information on attention. We addressed these gaps by employing a variant of the gaze cueing paradigm, simultaneously presenting participants with three faces. Block-wise, we manipulated whether one face (Identity condition) or one location (Location condition) contained a gaze cue entirely predictive of target location; all other cues were uninformative. Across trials, we manipulated the number of valid cues (number of faces gazing at target). We examined whether these two types of information (Identity vs. Location) were learned at a similar rate by statistically modelling cueing effects by trial count. Preregistered analyses returned no evidence for an interaction between condition, number of valid faces, and presence of the predictive element, indicating type of information did not affect participants’ ability to employ the predictive element to alter behaviour. Exploratory analyses demonstrated (i) response times (RT) decreased faster across trials for the Identity compared with Location condition, with greater decreases when the predictive element was present versus absent, (ii) RTs decreased across trials for the Location condition only when it was completed first, and (iii) social competence altered RTs across conditions and trial number. Our work demonstrates a nuanced relationship between cue utility, condition type, and social competence on group cueing.

尽管人们普遍认为他人的单次注视会引起注意力的转移,但有关多次注视对注意力的影响的研究却很有限,尽管现实世界中的社交线索往往是在群体中出现的。此外,人们对不同社交信息和非社交信息的可靠性不平等对注意力的影响也知之甚少。为了填补这些空白,我们采用了一种不同的凝视提示范式,同时向参与者展示三张面孔。我们分块操纵了一个面孔(身份条件)或一个位置(位置条件)是否包含完全预测目标位置的注视提示;所有其他提示均无信息。在所有试验中,我们对有效线索的数量(凝视目标的人脸数量)进行了控制。我们通过用试验次数对提示效果进行统计建模,来检验这两种信息(身份与位置)的学习率是否相似。预先登记的分析结果显示,没有证据表明条件、有效面孔数量和预测元素的存在之间存在交互作用,这表明信息类型并不影响参与者利用预测元素改变行为的能力。探索性分析表明:(i) 与 "位置 "条件相比,"身份 "条件下的反应时间(RT)在各次试验中下降得更快,当预测元素存在与不存在时,反应时间的下降幅度更大;(ii) 只有当 "位置 "条件下的反应时间首先完成时,反应时间才会在各次试验中下降;(iii) 社交能力会改变不同条件和试验次数下的反应时间。我们的研究表明,提示效用、条件类型和社交能力对群体提示的影响存在微妙的关系。

Task-order control in dual-tasks: Only marginal interactions between conflict at lower levels and higher processes of task organization 双重任务中的任务顺序控制:较低层次的冲突与较高层次的任务组织过程之间只有微弱的相互作用。

When simultaneously performing two tasks that share response properties, interference can occur. Besides general performance decrements, performance in the first task is worse when the second task requires a spatially incompatible response, known as the backward crosstalk effect (BCE). The size of this BCE, similar to congruency effects in conflict tasks, is subject to a sequential modulation, with a smaller BCE after incompatible compared to compatible trials. In the present study, we focus on a potential bidirectional interaction between crosstalk (and its resolution) at a lower level of task performance and higher-order processes of task organization. Two questions were of particular interest: First, do participants switch task order more frequently after a conflict-prone incompatible trial than after a compatible trial? Second, does changing task order influence the efficiency of conflict resolution, as indexed by the size of the sequential modulation of the BCE. Across four experiments, we only found marginal evidence for an influence of lower-level conflict on higher-order processes of task organization, with only one experiment revealing a tendency to repeat task order following conflict. Our results thus suggest practical independence between conflict and task-order control. When separating processes of task selection and task performance, the sequential modulation was generally diminished, suggesting that conflict resolution in dual-tasks can be disrupted by a deliberate decision about task order, or, alternatively, by a longer inter-trial interval. Finally, the study found a strong bias towards repeating the same task order across trials, suggesting that task-order sets not only impact task performance but also guide task selection.

当同时执行两项具有相同反应特性的任务时,可能会出现干扰。除了一般的成绩下降之外,当第二项任务需要空间上不相容的反应时,第一项任务的成绩也会下降,这就是所谓的后向串扰效应(BCE)。这种 BCE 的大小与冲突任务中的一致性效应类似,受顺序调节的影响,不相容试验后的 BCE 小于相容试验后的 BCE。在本研究中,我们将重点放在任务表现低层次的串扰(及其解决)与任务组织的高阶过程之间潜在的双向互动上。我们特别关注两个问题:首先,与相容试验相比,参与者是否在容易发生冲突的不相容试验后更频繁地转换任务顺序?其次,改变任务顺序是否会影响冲突解决的效率(以 BCE 的顺序调制大小为指标)。在四项实验中,我们只发现了低层次冲突对高阶任务组织过程产生影响的边际证据,只有一项实验揭示了冲突后重复任务顺序的倾向。因此,我们的结果表明冲突和任务顺序控制之间实际上是独立的。当把任务选择过程和任务执行过程分开时,顺序调节作用普遍减弱,这表明在双重任务中,冲突的解决可能会被任务顺序的有意决定所干扰,或者被较长的试验间隔所干扰。最后,研究发现,在试验中重复相同任务顺序的倾向性很强,这表明任务顺序集不仅会影响任务表现,还会指导任务选择。

Conflict-induced control refers to humans’ ability to regulate attention in the processing of target information (e.g., the color of a word in the color-word Stroop task) based on experience with conflict created by distracting information (e.g., an incongruent color word), and to do so either in a proactive (preparatory) or a reactive (stimulus-driven) fashion. Interest in conflict-induced control has grown recently, as has the awareness that effects attributed to those processes might be affected by conflict-unrelated processes (e.g., the learning of stimulus-response associations). This awareness has resulted in the recommendation to move away from traditional interference paradigms with small stimulus/response sets and towards paradigms with larger sets (at least four targets, distractors, and responses), paradigms that allow better control of non-conflict processes. Using larger sets, however, is not always feasible. Doing so in the Stroop task, for example, would require either multiple arbitrary responses that are difficult for participants to learn (e.g., manual responses to colors) or non-arbitrary responses that can be difficult for researchers to collect (e.g., vocal responses in online experiments). Here, we present a spatial version of the Stroop task that solves many of those problems. In this task, participants respond to one of six directions indicated by an arrow, each requiring a specific, non-arbitrary manual response, while ignoring the location where the arrow is displayed. We illustrate the usefulness of this task by showing the results of two experiments in which evidence for proactive and reactive control was obtained while controlling for the impact of non-conflict processes.

冲突诱发控制是指人类在处理目标信息(如颜色词 Stroop 任务中的词的颜色)时,根据与干扰信息(如不协调的颜色词)产生冲突的经验来调节注意力的能力,这种能力可以是主动的(准备性的),也可以是被动的(刺激驱动的)。最近,人们对冲突诱导控制的兴趣与日俱增,因为他们意识到,归因于这些过程的效果可能会受到与冲突无关的过程(如刺激-反应联想的学习)的影响。这种意识促使人们建议摒弃使用小刺激/反应集的传统干扰范式,转而使用较大刺激/反应集(至少四个目标、干扰物和反应)的范式,这种范式可以更好地控制非冲突过程。然而,使用较大的刺激/反应集并不总是可行的。例如,在施特罗普任务中这样做需要多个任意反应,这对参与者来说是很难学会的(如对颜色的手动反应),或者是非任意反应,这对研究人员来说是很难收集的(如在线实验中的发声反应)。在这里,我们提出了一种空间版的 Stroop 任务,它解决了上述许多问题。在这项任务中,参与者要对箭头指示的六个方向中的一个做出反应,每个方向都需要特定的、非任意的手动反应,同时忽略箭头显示的位置。我们通过展示两个实验的结果来说明这项任务的实用性,在这两个实验中,我们在控制非冲突过程影响的同时,获得了主动和被动控制的证据。

Visual short-term memory (VSTM), the ability to store information no longer visible, is essential for human behavior. VSTM limits vary across the population and are correlated with overall cognitive ability. It has been proposed that low-memory individuals are unable to select only relevant items for storage and that these limitations are greatest when memory demands are high. However, it is unknown whether these effects simply reflect task difficulty and whether they impact the quality of memory representations. Here we varied the number of items presented, or set size, to investigate the effect of memory demands on the performance of visual short-term memory across low- and high-memory groups. Group differences emerged as set size exceeded memory limits, even when task difficulty was controlled. In a change-detection task, the low-memory group performed more poorly when set size exceeded their memory limits. We then predicted that low-memory individuals encoding items beyond measured memory limits would result in the degraded fidelity of memory representations. A continuous report task confirmed that low, but not high, memory individuals demonstrated decreased memory fidelity as set size exceeded measured memory limits. The current study demonstrates that items held in VSTM are stored distinctly across groups and task demands. These results link the ability to maintain high quality representations with overall cognitive ability.

视觉短时记忆(VSTM)是一种存储不再可见信息的能力,对人类行为至关重要。视觉短时记忆的限制因人而异,并与整体认知能力相关。有人认为,低记忆力的人无法只选择相关的项目进行存储,而当记忆需求较高时,这种限制就会最大。然而,这些影响是否仅仅反映了任务难度,是否会影响记忆表征的质量,目前还不得而知。在这里,我们通过改变呈现项目的数量或集合大小来研究记忆需求对低记忆力组和高记忆力组视觉短时记忆表现的影响。即使在控制任务难度的情况下,当集合大小超过记忆极限时,也会出现组间差异。在变化检测任务中,当集合大小超过记忆极限时,低记忆力组的表现更差。因此,我们预测,低记忆力个体对超出测量记忆极限的项目进行编码会导致记忆表征的保真度下降。连续报告任务证实,当集合大小超过测量的记忆极限时,记忆力低的人的记忆保真度会下降,而记忆力高的人则不会。目前的研究表明,VSTM 中保存的项目在不同的组别和任务要求下会有不同的存储方式。这些结果将保持高质量表征的能力与整体认知能力联系起来。

Vestibular perceptual thresholds quantify sensory noise associated with reliable perception of small self-motions. Previous studies have identified substantial variation between even healthy individuals’ thresholds. However, it remains unclear if or how an individual’s vestibular threshold varies over repeated measures across various time scales (repeated measurements on the same day, across days, weeks, or months). Here, we assessed yaw rotation and roll tilt thresholds in four individuals and compared this intra-individual variability to inter-individual variability of thresholds measured across a large age-matched cohort each measured only once. For analysis, we performed simulations of threshold measurements where there was no underlying variability (or it was manipulated) to compare to that observed empirically. We found remarkable consistency in vestibular thresholds within individuals, for both yaw rotation and roll tilt; this contrasts with substantial inter-individual differences. Thus, we conclude that vestibular perceptual thresholds are an innate characteristic, which validates pooling measures across sessions and potentially serves as a stable clinical diagnostic and/or biomarker.

前庭知觉阈值量化了与可靠感知微小自我运动相关的感觉噪声。以往的研究发现,即使是健康人的阈值之间也存在很大差异。然而,目前仍不清楚个体的前庭阈值在不同时间尺度(同一天、不同天、不同周或不同月)的重复测量中是否或如何变化。在这里,我们评估了四个人的偏航旋转和滚动倾斜阈值,并将这种个体内变异性与一个大的年龄匹配队列中每个人只测量一次的阈值的个体间变异性进行了比较。为了进行分析,我们对没有潜在变异性(或变异性被操纵)的阈值测量进行了模拟,以便与经验观察到的变异性进行比较。我们发现,无论是偏航旋转还是滚动倾斜,个体内部的前庭阈值都非常一致;这与个体间的巨大差异形成了鲜明对比。因此,我们得出结论,前庭知觉阈值是一种与生俱来的特征,它验证了跨疗程集合测量的有效性,并有可能成为一种稳定的临床诊断和/或生物标志物。

People tend to employ suboptimal attention control strategies during visual search. Here we question why people are suboptimal, specifically investigating how knowledge of the optimal strategies and the time available to apply such strategies affect strategy use. We used the Adaptive Choice Visual Search (ACVS), a task designed to assess attentional control optimality. We used explicit strategy instructions to manipulate explicit strategy knowledge, and we used display previews to manipulate time to apply the strategies. In the first two experiments, the strategy instructions increased optimality. However, the preview manipulation did not significantly boost optimality for participants who did not receive strategy instruction. Finally, in Experiments 3A and 3B, we jointly manipulated preview and instruction with a larger sample size. Preview and instruction both produced significant main effects; furthermore, they interacted significantly, such that the beneficial effect of instructions emerged with greater preview time. Taken together, these results have important implications for understanding the strategic use of attentional control. Individuals with explicit knowledge of the optimal strategy are more likely to exploit relevant information in their visual environment, but only to the extent that they have the time to do so.

在视觉搜索过程中,人们往往会采用次优的注意力控制策略。在这里,我们要探讨的问题是,为什么人们会采用次优策略,特别是要研究有关最优策略的知识和应用这些策略的可用时间会如何影响策略的使用。我们使用了 "自适应选择视觉搜索"(ACVS),这是一项旨在评估注意力控制最优性的任务。我们使用明确的策略指令来操纵明确的策略知识,并使用显示预览来操纵应用策略的时间。在前两项实验中,策略指导提高了优化性。然而,对于没有接受策略指导的参与者来说,预览操作并没有显著提高他们的最优性。最后,在实验 3A 和 3B 中,我们联合操纵了预览和指导,并增加了样本量。预览和指导都产生了显著的主效应;此外,它们还产生了显著的交互作用,即预览时间越长,指导的有利效应就越明显。综合来看,这些结果对于理解注意力控制策略的使用具有重要意义。对最佳策略有明确认识的个体更有可能利用视觉环境中的相关信息,但前提是他们有时间这样做。
