The lateralised bias of spatial neglect can be modulated by concurrent non-lateralised impairments. For instance, people with left neglect may have spatial working memory deficits that prevent them from keeping track of locations visited in visual search tasks such as target cancellation. Not only do they omit targets in some parts of the array but they may revisit and re-cancel targets in other parts, and this re-cancellation behaviour increases dramatically in ‘invisible’ conditions, in which touching a target leaves no visible trace. It has been proposed that spatial memory deficits are the main reason for the rise of re-cancellation errors in invisible cancellation conditions. This idea predicts that spatial memory abilities should correlate with re-cancellation behaviour; but this expected relationship has never been demonstrated. The present study takes an exploratory approach to describing the behaviour of 18 people with left visual neglect, following right hemisphere stroke, on touchscreen tests of spatial working memory and target cancellation. We show that people with neglect who are less able to remember locations in a spatial memory task tend to make more re-cancellation errors in invisible cancellation conditions. We also describe an apparent trade-off, in which some people with neglect make many more re-cancellation errors, whilst others make many more target omissions. We suggest that the influence of spatial memory deficits on invisible cancellation tasks can be more fully captured by considering both types of errors, rather than re-cancellations only.

空间忽视的侧偏性可以通过并发的非侧偏性损伤来调节。例如，患有左忽视的人可能有空间工作记忆缺陷，这使他们无法在视觉搜索任务（如目标取消）中跟踪所访问的位置。它们不仅会忽略阵列中某些部分的目标，还可能重新访问并重新取消其他部分的目标，并且这种重新取消行为在“不可见”条件下急剧增加，在这种情况下，接触目标不会留下可见的痕迹。有研究认为，空间记忆缺陷是隐性消去条件下重消错误增加的主要原因。这一观点预测空间记忆能力应该与再取消行为相关；但这种预期的关系从未得到证实。本研究采用一种探索性的方法来描述18名右半球中风后左视觉忽视患者在空间工作记忆和目标取消的触摸屏测试中的行为。我们发现，在空间记忆任务中，被忽视的人在记忆位置的能力较差，在看不见的取消条件下，他们往往会犯更多的再取消错误。我们还描述了一种明显的权衡，在这种权衡中，一些被忽视的人会犯更多的重消错误，而另一些人则会犯更多的目标遗漏。我们建议空间记忆缺陷对无形取消任务的影响可以通过考虑两种类型的错误而不是仅仅重新取消任务来更充分地捕捉。

The neurological process of mirror generalization in memory, also known as mirror symmetrization, presents a real dilemma for typically developing 5- to 6-year-olds when learning to write characters (digits and letters). Should they write the digit 3 oriented to the left, that is correctly, or to the right, which leads to its mirror image

ε

? It has been anecdotally suggested that boys are more prone to mirror-writing than girls, but there is no scientific evidence for this idea. The present article gathers data from 691 children in the upper section of the French école maternelle (age between 5 and 6 ½), who each wrote the digits 0 to 9 four times under dictation and not necessarily in their natural order. Both simple and complex (mixed-effects linear regression) statistical comparisons on the percentages of digit reversal, show a substantial difference: girls produce more mirror reversals than boys. And yet the reversal curves as a function of the digits are quite similar between the two sexes (r = .97).

It has been proposed that mirror reversal of characters results from the left orientation of some of them (e.g., 3, 7, J, Z), that is, in an orientation contrary to the direction of writing in our Western cultures. The present investigation shows that (1) this character orientation hypothesis (choosing to write characters in the same orientation as sentence writing) better explains reversals than the counterclockwise hypothesis (children are trained to draw circles counter-clockwise to prepare for attached cursive writing); (2) the study of the stability of reversals additionally supports the explanation of mirror writing by the left orientation of the digits (1, 2, 3, 7 and, less obviously, 9); but (3) neither of the preceding findings (left-right orientation and stability) provided a convincing explanation for the aforementioned gender difference.

记忆中镜像泛化的神经学过程，也被称为镜像对称，在学习写字符（数字和字母）时给5到6岁的孩子带来了一个真正的困境。数字3应该向左写，这是正确的，还是向右写，这导致它的镜像ε？有传闻称，男孩比女孩更倾向于镜像书写，但这一观点没有科学依据。本文收集了691名法国儿童（年龄在5岁到6岁半之间）的数据，他们在口述的情况下将数字0到9写了四次，不一定是按自然顺序写的。简单和复杂（混合效应线性回归）的数字反转百分比统计比较显示出实质性差异：女孩比男孩产生更多的镜像反转。然而，两性之间的反向曲线作为手指的函数是非常相似的（r = .97）。有人提出，汉字的镜像反转是由于其中一些字符（例如，3,7,j， Z）的向左方向造成的，也就是说，与我们西方文化中的书写方向相反。本研究表明：(1)汉字朝向假设（选择与句子书写方向相同的汉字）比逆时针假设（儿童被训练逆时针画圆圈以准备附体草书书写）更能解释反转；(2)对反转稳定性的研究进一步支持了数字左向书写的解释（1、2、3、7和不太明显的9）；但是(3)之前的研究结果（左右取向和稳定性）都不能令人信服地解释上述性别差异。

Influential theories of complex behaviour invoke the notion of cognitive control modulated by conflict between counterfactual actions. Medial frontal cortex, notably the anterior cingulate cortex, has been variously posited as critical to such conflict detection, resolution, or monitoring, largely based on correlative data from functional imaging. Examining performance on the most widely used “conflict” task—Stroop—in a large cohort of patients with focal brain injury (N = 176), we compare anatomical patterns of lesion-inferred neural substrate dependence to those derived from functional imaging, meta-analytically summarised. Our results show that whereas performance is sensitive to the integrity of left lateral frontal regions implicated by functional imaging, it does not depend on medial frontal cortex, despite sampling adequate to reveal robust medial effects in the context of phonemic fluency. We suggest that medial frontal cortex is not critically invoked by Stroop and proceed to review the conceptual grounds for rejecting the core notion of conflict-driven cognitive control.

复杂行为的有影响力的理论援引认知控制的概念，由反事实行为之间的冲突调节。内侧额叶皮层，特别是前扣带皮层，在很大程度上基于功能成像的相关数据，被认为是冲突检测、解决或监测的关键。在一大批局灶性脑损伤患者（N = 176）中，研究了最广泛使用的“冲突”任务（stroop）的表现，我们比较了病变推断的神经基质依赖的解剖模式和功能成像得出的解剖模式，并进行了荟萃分析总结。我们的研究结果表明，尽管表现对与功能成像有关的左侧外侧额叶区域的完整性敏感，但它并不依赖于内侧额叶皮层，尽管取样足够充分地揭示了音素流畅性背景下强大的内侧效应。我们认为内侧额叶皮层并没有被Stroop批判性地引用，并继续回顾拒绝冲突驱动认知控制核心概念的概念依据。

Closing-in behavior (CIB) is characterized by the placement of the graphic copy near (Near CIB) or even on the top of (Overlap CIB) the stimulus to be reproduced. Although CIB has received little attention in the literature, Sergio Della Sala and colleagues made important contributions to the understanding of the phenomenon. They noted that CIB is often observed in Alzheimer's Disease but is also present in other forms of dementia and mild cognitive impairment and stroke; they argued that CIB may reflect a deficit in executive function, rather than working memory, and that the phenomenon occurs more frequently in dual task conditions. Importantly, they demonstrated that CIB may not be specific to copying but may instead reflect a general deficit in decoupling movement location from the focus of attention. In the present study, we explored these observations in a mixed sample of 106 participants (AD n = 37, frontal stroke n = 25, other forms of dementia n = 24, and normal controls n = 20). First, we confirmed that CIB is equally common in AD, other forms of dementia and frontal stroke. Second, we confirmed the association between CIB and executive function deficits. Third, we showed that individuals with CIB are more likely to exhibit the phenomenon in dual task situations, in which line-drawing is associated with an unrelated secondary task (tapping, counting, or counting backward). The present work supports and extends the contributions of Della Sala and colleagues demonstrating that CIB is enhanced when the general attentional load of the task increases.

闭合行为（CIB）的特征是将图形副本放置在待复制刺激的附近（near CIB）甚至顶部（Overlap CIB）。尽管CIB在文献中很少受到关注，但塞尔吉奥·德拉·萨拉及其同事对理解这一现象做出了重要贡献。他们指出，CIB经常在阿尔茨海默病中观察到，但也存在于其他形式的痴呆、轻度认知障碍和中风中；他们认为CIB可能反映了执行功能的缺陷，而不是工作记忆的缺陷，而且这种现象在双重任务条件下更频繁发生。重要的是，他们证明了CIB可能不是特定于复制的，而是反映了运动位置与注意力焦点解耦的普遍缺陷。在本研究中，我们在106名参与者的混合样本中探讨了这些观察结果（AD n = 37，额叶中风n = 25，其他形式的痴呆n = 24，正常对照n = 20）。首先，我们证实CIB在阿尔茨海默病、其他形式的痴呆和额叶中风中同样常见。其次，我们证实了CIB与执行功能缺陷之间的联系。第三，我们发现CIB患者在双重任务情境下更有可能表现出这种现象，在双重任务情境下，画线与一个不相关的次要任务（敲击、计数或向后计数）有关。本研究支持并扩展了Della Sala及其同事的研究成果，即当任务的一般注意负荷增加时，CIB会增强。

Binding, a critical cognitive process likely mediated by attention, is essential for creating coherent object representations within a scene. This process is vulnerable in individuals with dementia, who exhibit deficits in visual working memory (VWM) binding, primarily tested using abstract arrays of standalone objects. To explore how binding operates in more realistic settings across the lifespan, we examined the impact of object saliency and semantic consistency on VWM binding and the role of overt attention. Using an eye-tracking change detection task, we compared younger adults, healthy older adults, and individuals with Mild Cognitive Impairment (MCI). Participants were presented with naturalistic scenes and asked to detect changes in the identity and/or location of objects that were either semantically consistent or inconsistent with their scene context. Across all age groups, semantically inconsistent objects were prioritised during encoding, leading to better change detection than consistent objects. Highly salient objects decreased the inconsistency advantage while being detrimental to detection accuracy when inspected at longer latencies to the first fixation. Longer fixation durations on the critical object were beneficial for recognition. In contrast, delayed initial inspection or frequent subsequent fixations on other objects were detrimental to detection, regardless of age or cognitive impairment. These findings challenge the notion of generalised semantic memory impairment in the prodromal stages of dementia and highlight the importance of efficient attentional control in supporting VWM binding, even in the face of cognitive decline. Overall, preserved low-level and high-level mechanisms of object-scene integration can compensate for age-related cognitive decline, enabling successful binding in naturalistic contexts.

绑定是一个关键的认知过程，可能由注意力介导，对于在场景中创建连贯的对象表征至关重要。这一过程在痴呆症患者中是脆弱的，他们表现出视觉工作记忆（VWM）结合的缺陷，主要使用独立对象的抽象数组进行测试。为了探索在整个生命周期中绑定如何在更现实的环境中运作，我们研究了对象显著性和语义一致性对VWM绑定的影响以及显性注意的作用。使用眼动追踪变化检测任务，我们比较了年轻人、健康老年人和轻度认知障碍（MCI）患者。参与者被呈现在自然场景中，并被要求检测物体的身份和/或位置的变化，这些物体在语义上与场景上下文一致或不一致。在所有年龄组中，语义不一致的对象在编码过程中被优先考虑，导致比一致的对象更好的变化检测。高度突出的物体减少了不一致的优势，但当在第一次固定的较长时间内检查时，对检测精度有害。长时间注视关键物体有利于识别。相比之下，无论年龄或认知障碍如何，延迟初始检查或随后频繁盯着其他物体都不利于检测。这些发现挑战了痴呆症前驱阶段普遍语义记忆障碍的概念，并强调了有效的注意力控制在支持VWM结合方面的重要性，即使在面对认知衰退时也是如此。总的来说，保留的低水平和高水平的对象-场景整合机制可以弥补与年龄相关的认知衰退，使其在自然环境中成功结合。
