Earlier work has shown that the eyes preferably select stimuli that are presented close to central fixation over stimuli presented further away, suggesting the existence of a central selection bias. However, so far studies have confounded retinal eccentricity with distance from the center of a display, and the observed effects may thus have been driven by what is known as the central fixation bias, which is the preference for items near the center of a display rather than the center of the retina. This study aimed to dissociate the central selection bias from the central fixation bias, and to uncover its time course. In two experiments, participants were instructed to make a single eye movement to one of two simultaneously presented singletons. The singletons were always presented at the same distance from the center of the display (thus controlling for the central fixation bias) but their eccentricity relative to the initial fixation point was varied (thus allowing for a central selection bias to operate). When the two singletons were displayed at different eccentricities, participants preferred selecting the nearest item. This central selection bias occurred rapidly and transiently, peaking around 230 ms and lasting until approximately 320 ms after display onset. Together, these results suggest that retinal eccentricity is a major factor when multiple objects compete for selection.

早期的研究表明，眼睛更倾向于选择靠近中心注视点的刺激，而不是远离中心注视点的刺激，这表明存在中心选择偏差。然而，到目前为止，研究已经混淆了视网膜偏心与距离显示中心的距离，因此观察到的影响可能是由所谓的中心注视偏差驱动的，这是对显示中心附近的物品的偏好，而不是视网膜中心。本研究旨在分离中心选择偏差和中心注视偏差，并揭示其时间过程。在两个实验中，参与者被要求对同时呈现的两张单张图片中的一张做一次眼球运动。单子总是在距离显示器中心相同的距离上呈现（从而控制中心固定偏差），但它们相对于初始固定点的偏心是不同的（从而允许中心选择偏差的操作）。当两个单品以不同的偏心位置显示时，参与者倾向于选择最近的一个。这种中心选择偏差发生迅速而短暂，在230毫秒左右达到峰值，并持续到大约320毫秒后显示开始。总之，这些结果表明，当多个物体竞争选择时，视网膜偏心是一个主要因素。

Scene context is known to significantly influence visual perception, enhancing object recognition particularly under challenging viewing conditions. Behavioral and neuroimaging studies suggest that high-level scene information modulates activity in object-selective brain areas through top-down mechanisms, yet the underlying mechanism of this process remains unclear. Here, we introduce a biologically inspired context-based computational model (CBM) that integrates scene context into object recognition via an explicit feedback mechanism. CBM consists of two distinct pathways: Object_CNN, which processes localized object features, and Place_CNN, which extracts global scene information to modulate object processing. We compare CBM to a standard feedforward model, AlexNet, in a multiclass object recognition task under varying levels of visual degradation and occlusion. CBM significantly outperformed a standard feedforward model (AlexNet), demonstrating the effectiveness of structured contextual feedback in resolving ambiguous or degraded visual input. However, behavioral experiments revealed that while humans also benefited from congruent context — particularly at high occlusion levels — the effect was modest. Human recognition remained relatively robust even without contextual support, suggesting that mechanisms such as global shape processing and pattern completion, likely mediated by local recurrent processes, play a dominant role in resolving occluded input. These findings highlight the potential of contextual feedback for enhancing model performance, while also underscoring key differences between human and models. Our results point toward the need for models that combine context-sensitive feedback with object-intrinsic local recurrent processes to more closely approximate the flexible and resilient strategies of human perception.

众所周知，场景环境会显著影响视觉感知，增强物体识别，特别是在具有挑战性的观看条件下。行为和神经影像学研究表明，高水平的场景信息通过自上而下的机制调节了目标选择脑区的活动，但这一过程的潜在机制尚不清楚。在这里，我们引入了一种受生物学启发的基于上下文的计算模型（CBM），该模型通过明确的反馈机制将场景上下文集成到对象识别中。CBM包括两个不同的路径：Object_CNN和Place_CNN，前者处理局部目标特征，后者提取全局场景信息以调制目标处理。我们将CBM与标准前馈模型AlexNet在不同程度的视觉退化和遮挡下的多类物体识别任务中进行比较。CBM显著优于标准前馈模型（AlexNet），证明了结构化上下文反馈在解决模糊或退化的视觉输入方面的有效性。然而，行为实验显示，虽然人类也从一致的语境中受益，尤其是在高闭塞水平下，但效果是有限的。即使没有上下文支持，人类识别仍然相对强大，这表明可能由局部循环过程介导的全局形状处理和模式完成等机制在解决闭塞输入中起主导作用。这些发现强调了上下文反馈在提高模型性能方面的潜力，同时也强调了人类和模型之间的关键差异。我们的研究结果表明，需要将上下文敏感反馈与对象固有的局部循环过程相结合的模型，以更接近人类感知的灵活和弹性策略。

Attention-Deficit/Hyperactivity Disorder (ADHD) is a prevalent neurodevelopmental condition in young populations and is often associated with visual disturbances. This study investigated clinical measurements in individuals with ADHD and compared them with individuals without ADHD. This study included 80 participants: 40 with ADHD and 40 age- and sex-matched controls. The mean age ± standard deviation was 19.93 ± 6.42 (range 6–36). The optometric tests performed assessed accommodative and binocular visual functions, including accommodative amplitude, monocular and binocular accommodative facility, Cover Test, near point of convergence, monocular estimated method, and calculated accommodation convergence/accommodation ratio. Subgroup analysis within the ADHD group, based on sex and medication use, explored the associations with optometric findings. The ADHD group showed a significantly higher lag of accommodation (+0.30 ± 0.17 D) than the control group (+0.18 ± 0.23 D) and a higher accommodative amplitude (ADHD group = 13.15 ± 1.73, control group = 12.07 ± 1.60). ADHD was also associated with a higher prevalence of near-heterophoria. No differences were observed between medicated and medication-free at testing individuals with ADHD. Furthermore, males demonstrated higher near heterophoria than females, with males having significantly more phorias at near. The results of this paper demonstrate that individuals with ADHD commonly experience compromised accommodative responses and a heightened occurrence of heterophoria compared with individuals without ADHD. These results emphasize the importance of eye exams for ADHD patients, as vision issues may reduce attention and concentration, especially for near-work tasks.

注意缺陷/多动障碍（ADHD）是年轻人中普遍存在的神经发育疾病，通常与视觉障碍有关。本研究调查了ADHD患者的临床测量结果，并将其与非ADHD患者进行了比较。这项研究包括80名参与者：40名ADHD患者和40名年龄和性别匹配的对照组。平均年龄±标准差为19.93±6.42（范围6 ~ 36）。验光测试评估了调节和双眼视觉功能，包括调节幅度、单眼和双眼调节设施、覆盖测试、近会聚点、单眼估计方法和计算调节会聚/调节比。ADHD组的亚组分析，基于性别和药物使用，探讨了与验光结果的关系。ADHD组调节滞后时间（+0.30±0.17 D）显著高于对照组（+0.18±0.23 D），调节幅度（ADHD组= 13.15±1.73，对照组= 12.07±1.60）显著高于对照组（+0.18±0.23 D）。多动症还与近斜视的较高患病率有关。在对ADHD患者进行测试时，没有观察到服药和不服药之间的差异。此外，男性比女性表现出更高的近斜视，男性的近斜视明显更多。本文的结果表明，与没有ADHD的个体相比，患有ADHD的个体通常会经历妥协的适应性反应和更高的异视发生率。这些结果强调了对多动症患者进行眼科检查的重要性，因为视力问题可能会降低注意力和集中力，尤其是在接近工作的任务中。

The stereoscopic system is typically tested by measuring its response to sinusoidal disparity corrugations. Previous research using psychophysical methods like masking and adaptation has provided evidence about the existence of disparity mechanisms tuned to spatial frequency and orientation. Analyses based on individual differences have confirmed only the existence of disparity mechanisms tuned to spatial frequency. The main objective of this study is to investigate the existence of orientation-selective disparity mechanisms using an individual differences approach. We measured the disparity thresholds of 37 subjects using sinusoidal disparity corrugations constructed from dynamic random-dot stereograms with spatial frequencies of 0.1, 0.4, and 0.8 cpd and 7 orientations (ranging from 0° to 90° in steps of 15°). Stereo thresholds for 0.1 cpd showed a strong anisotropy with disparity thresholds increasing from 90° (horizontal) to 0° (vertical). This anisotropy was reduced for the other two spatial frequencies. Component and factor analyses revealed that closer orientations tend to group together, suggesting the presence of underlying orientation-selective mechanisms in stereovision. These results provide new evidence for disparity channels tuned to orientation underlying the processing of disparity corrugations.

立体系统通常通过测量其对正弦视差波纹的响应来测试。先前使用心理物理方法（如掩蔽和适应）的研究已经提供了证据，证明存在调整到空间频率和方向的差异机制。基于个体差异的分析只证实了空间频率的差异机制的存在。本研究的主要目的是利用个体差异的方法来探讨取向选择差异机制的存在。我们使用动态随机点立体图（空间频率为0.1、0.4和0.8 cpd）和7个方向（从0°到90°，步长为15°）构建的正弦视差波形测量了37名受试者的视差阈值。0.1 cpd立体阈值表现出较强的各向异性，视差阈值从90°（水平）增加到0°（垂直）。对于其他两个空间频率，这种各向异性被减小了。成分分析和因子分析表明，较近的定向倾向于聚集在一起，表明立体视觉中存在潜在的定向选择机制。这些结果为视差波折加工背后的视差通道定向调谐提供了新的证据。

Eye-hand coordination is a key aspect of visuomotor control essential for performing most daily activities. Disruption in visuomotor control, characterized by slower arm movements and grasping errors, has been documented in children with amblyopia. This study aimed to characterize the effects of amblyopia on the temporal pattern of eye and hand coordination during the performance of a task that involves reaching, precision grasping, and placement. The study recruited 28 children with a history of amblyopia and 56 typically developing peers (age range 6–14 years). Children performed a bead-threading task while their eyes and hand movements were recorded concurrently. As hypothesized, children with amblyopia demonstrated poorer task performance, with greater deficits for the object manipulation compared to the reaching (transport) components. In comparison to their peers with normal vision, children with amblyopia had shorter reaction time for initiating eye and hand movement, longer object fixation duration to guide grasp execution and object placement, and lower eye-hand latency difference for the second movement indicating that the hand movement preceded eye initiation. These results suggest that children with amblyopia have poorer motor planning ability, which impacts movement execution. Longer fixations during object manipulations indicate that more time is required to transform the noisy visual input into a motor response. Overall, the study adds to the growing body of evidence highlighting deficits in visuomotor control in amblyopia.

眼手协调是视觉运动控制的一个关键方面，对执行大多数日常活动至关重要。视觉运动控制的中断，以手臂运动缓慢和抓握错误为特征，已经在弱视儿童中得到证实。本研究旨在描述弱视在执行涉及伸手、精确抓取和放置的任务时对眼手协调的时间模式的影响。这项研究招募了28名有弱视病史的儿童和56名正常发育的同龄人（年龄在6-14岁之间）。孩子们在执行穿线任务时，他们的眼睛和手的运动同时被记录下来。正如假设的那样，弱视儿童表现出较差的任务表现，与到达（运输）部分相比，他们在物体操作方面的缺陷更大。与视力正常的同龄人相比，弱视儿童启动眼手动作的反应时间更短，引导抓握执行和物体放置的物体注视时间更长，第二次动作的眼手潜伏期差更小，说明手动作先于眼手动作。这些结果表明弱视儿童的运动计划能力较差，影响运动执行。在物体操作过程中，长时间的注视表明需要更多的时间将嘈杂的视觉输入转化为运动反应。总的来说，这项研究增加了越来越多的证据，强调了弱视在视觉运动控制方面的缺陷。

Conventional visual acuity (VA) tests, using black optotypes on white background, may not fully detect subtle ON-pathway amblyopia deficits or increases in visual dark dominance. This pilot study tests the hypothesis that VA testing with reverse contrast polarity, white optotypes on black background, is more sensitive in detecting amblyopia than conventional VA testing. Two groups of children aged 8–12 were enrolled. The amblyopic group (N = 13) had a best-corrected VA of 20/32 or worse in the amblyopic eye and an interocular VA difference of ≥ 0.2 logMAR. The normal control group (N = 16) had best-corrected VA equal to or better than 20/25 and an interocular VA difference of ≤ 0.1 logMAR. Monocular VA was tested for each polarity using an ETDRS program using the Amblyopia Treatment Study protocol, with results reported as a Score. Two optotype polarities were tested in randomized order, and tests were repeated after a 30-minute interval. VA was compared among amblyopic, fellow, and the right eyes of the control group for both polarities. For amblyopic eyes, the mean VA Score was significantly lower for white optotypes than for black optotypes by 3.6 letters or approximately 0.07 logMAR, indicating that amblyopic eyes had more difficulty seeing white than black optotypes. For fellow eyes, the mean Score was also significantly lower for white than for black optotypes. No significant differences in mean Scores between two polarities were found within the control eyes. Our findings suggest that visual acuity testing with reverse polarity could be more sensitive to detect amblyopia in children.

传统的视敏度（VA）测试，在白色背景上使用黑色视型，可能不能完全检测到细微的on通路弱视缺陷或视觉黑暗优势的增加。本初步研究验证了反向对比极性、黑色背景下的白光视视检测对弱视的检测比传统视差测试更敏感的假设。研究人员招募了两组8-12岁的儿童。弱视组（N = 13）的最佳矫正视差为20/32或更差，眼间视差差≥0.2 logMAR。正常对照组（N = 16）的最佳矫正眼压等于或优于20/25，眼间眼压差≤0.1 logMAR。使用ETDRS程序，使用弱视治疗研究方案，对每个极性的单眼VA进行测试，并将结果作为评分报告。按随机顺序测试两种视型极性，每隔30分钟重复测试一次。比较弱视组、右眼组和对照组的视电位。对于弱视眼，白色视型的平均VA评分比黑色视型低3.6个字母或约0.07 logMAR，表明弱视眼比黑色视型更难以看到白色。对于同类眼睛来说，白色眼睛的平均得分也明显低于黑色眼睛。在对照眼内，两极性的平均得分无显著差异。我们的研究结果表明，反极性视力测试可以更灵敏地检测儿童弱视。

Our findings suggest that visual acuity testing with reverse polarity could be more sensitive to detect amblyopia in children.</div></div>","PeriodicalId":23670,"journal":{"name":"Vision Research","volume":"237 ","pages":"Article 108694"},"PeriodicalIF":1.4,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145118215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies have demonstrated that density of texture elements is an important perceptual aspect of textural appearance, and can enable texture segmentation in the absence of other cues. We compared segmentation thresholds for two kinds of second-order boundaries comprised of two species of micropatterns (e.g., horizontal and vertical Gabors): (1) Feature boundaries, with the same number of total micropatterns on opposite sides but different numbers of each micropattern species within each side, and (2) Density boundaries, with different numbers of total micropatterns on opposite sides, but with the same number of both micropattern species within each side. Contrary to the predictions of a standard late-pooling Filter-Rectify-Filter (FRF) model in which different micropattern specific first-order channels are analyzed by different second stage filters before pooling, we observed lower segmentation thresholds for density boundaries than feature boundaries. This suggests that density boundaries may be detected by a different, early-pooling mechanism. In a second experiment, we considered how two species of micropatterns combine for boundary segmentation. When two single-micropattern-species density boundaries are superimposed in-phase to form a new density boundary, the boundaries formed by each micropattern species combine via probability summation. By contrast, when two single-micropattern-species density boundaries are superimposed in opposite-phase to form a feature boundary, segmentation performance is worse than for either single-micropattern-species boundary alone. We conclude that the mechanisms for density-based texture segmentation are not identical to the mechanisms for feature-based segmentation and that density-sensitive mechanisms most likely integrate across multiple first-order filters responsive to different micropattern species.

先前的研究表明，纹理元素的密度是纹理外观的一个重要感知方面，可以在没有其他线索的情况下实现纹理分割。我们比较了由两种微图案组成的两种二级边界（如水平Gabors和垂直Gabors）的分割阈值：(1)特征边界，相对侧微图案总数相同，但每侧微图案种数不同；(2)密度边界，相对侧微图案总数不同，但每侧微图案种数相同。与标准的延迟池化滤波-校正-滤波（FRF）模型的预测相反，我们观察到密度边界的分割阈值低于特征边界。在该模型中，不同的微模式特定的一阶通道在池化之前由不同的第二阶段滤波器分析。这表明密度边界可以通过不同的早期池化机制来检测。在第二个实验中，我们考虑了两种微模式如何结合在一起进行边界分割。当两个单一微图案-物种密度边界相叠加形成新的密度边界时，各微图案物种形成的密度边界通过概率求和组合在一起。相比之下，当两个单微图案-物种密度边界以相反的相位叠加形成特征边界时，分割性能比单独使用单个微图案-物种边界差。我们得出结论，基于密度的纹理分割的机制与基于特征的纹理分割的机制不同，密度敏感的机制很可能集成了多个一阶滤波器，响应不同的微图案种类。

Monocular deprivation (MD) amblyopia caused by a dense unilateral congenital or infantile cataract leads to both sensory and ocular motor deficits, which can in turn affect motor performance. Previous research shows reduced fine motor skills in children with MD amblyopia on standardized tasks. Here, we evaluate eye-hand coordination during visually-guided reaching in MD amblyopia. A group of 17 children aged 7–15 years with MD amblyopia resulting from a unilateral cataract and a group of 41 age-similar control children were enrolled. During binocular viewing, children’s reaching movements (LEAP Motion Controller) and eye movements (EyeLink 1000 binocular eye tracker) were recorded as they reached to touch a dot displayed at one of four locations (±5 deg or ±10 deg) on a computer monitor. Saccade and reach kinematic measures were assessed between groups, and factors associated with impairments in the MD amblyopia group were evaluated. The MD amblyopia group as a whole had impaired saccade (lower saccade gain, reduced saccade precision, more reach-related saccades) and reach (longer total reach duration, slower peak velocity, reduced touch accuracy) kinematics compared to controls. However, performance was worse in those with a poorer visual acuity outcome (≥0.7 logMAR) compared to good visual acuity outcome (≤0.6 logMAR). MD amblyopia impacts the development of eye-hand coordination during reaching, particularly in those with a poorer visual acuity outcome. Longer deceleration in the final approach and more reach-related saccades may suggest an inability to adapt or form an efficient compensatory strategy and may also be indicative of impaired on-line control.

单眼剥夺（MD）弱视由密集的单侧先天性或婴儿白内障引起，可导致感觉和眼运动缺陷，进而影响运动表现。先前的研究表明，患有中度弱视的儿童在标准化任务中的精细运动技能有所下降。在这里，我们评估视觉引导下MD弱视伸手时的眼手协调。招募了17名7-15岁单侧白内障导致的MD弱视儿童和41名年龄相近的对照组儿童。在双眼观看期间，当儿童伸手触摸电脑显示器上显示的四个位置（±5度或±10度）之一的点时，他们的伸手动作（LEAP运动控制器）和眼动（EyeLink 1000双目眼动仪）被记录下来。评估两组间的扫视和屈伸运动测量，并评估与MD弱视组损伤相关的因素。与对照组相比，MD弱视组整体上的扫视功能受损（扫视增益降低，扫视精度降低，更多与屈伸相关的扫视）和屈伸运动（总屈伸持续时间更长，峰值速度更慢，触摸精度降低）。然而，与视力良好（≤0.6 logMAR）的患者相比，视力较差（≥0.7 logMAR）的患者表现更差。MD弱视影响伸手过程中手眼协调的发展，特别是那些视力较差的人。最后进近减速时间较长和与到达有关的跳频较多，可能表明无法适应或形成有效的补偿策略，也可能表明联机控制受损。

Populations of sensory neurons are not homogeneous. Even neighboring neurons located in the same brain area can process identical stimuli in significantly different ways. Retinal ganglion cells (RGCs) are a prominent example of such heterogeneity — they exhibit diverse properties whose computational role and purpose remain mysterious. In this review, we explore normative theories of neural computation that attempt to explain the origins and role of functional variability in the retina. We first express a general mathematical formulation of normative theories of neural computation and identify components of these theories that can explain the heterogeneity of sensory populations. We then organize existing theoretical studies of retinal coding according to the factors they highlight as explanations of the computational diversity in the retina — the beginning of the visual hierarchy.

感觉神经元的种群并不均匀。即使是位于同一大脑区域的相邻神经元也可以以明显不同的方式处理相同的刺激。视网膜神经节细胞（RGCs）是这种异质性的一个突出例子-它们表现出不同的特性，其计算作用和目的仍然是神秘的。在这篇综述中，我们探讨了神经计算的规范理论，试图解释视网膜功能变异性的起源和作用。我们首先表达了神经计算规范理论的一般数学公式，并确定了这些理论的组成部分，可以解释感官群体的异质性。然后，我们根据他们强调的解释视网膜计算多样性的因素，组织现有的视网膜编码理论研究-视觉层次的开始。

Humans not only perceive material properties of natural surfaces but also evaluate their affective qualities, such as pleasantness or unpleasantness. Recent psychophysical studies suggest that such emotional impressions can arise directly from low-level image statistics, independent of object recognition. To elucidate the neural mechanisms underlying these immediate affective responses, we recorded visual evoked potentials (VEPs) while participants viewed 150 images of natural surfaces varying in affective valence. We identified occipital VEP components emerging around 100–150 ms after stimulus onset that were significantly correlated with subjective unpleasantness ratings. Moreover, these unpleasantness-related VEPs were accurately predicted by a linear combination of VEP components associated with a small set of diagnostic image statistics. Our findings indicate that early visual cortical activity encodes image features that give rise to unpleasant affective responses, supporting the notion that rapid, low-level visual processing can directly contribute to the emotional evaluation of visual textures and materials.

人类不仅能感知自然表面的物质特性，还能评估其情感品质，如愉悦或不愉悦。最近的心理物理学研究表明，这种情绪印象可以直接产生于低水平的图像统计，独立于物体识别。为了阐明这些即时情感反应背后的神经机制，我们在参与者观看150张不同情感效价的自然表面图像时记录了视觉诱发电位（vep）。我们发现在刺激开始后100-150毫秒左右出现的枕部VEP成分与主观不愉快评分显著相关。此外，通过与一小组诊断图像统计相关的VEP成分的线性组合，可以准确预测这些与不愉快相关的VEP。我们的研究结果表明，早期视觉皮质活动编码的图像特征会引起不愉快的情感反应，这支持了快速、低水平的视觉处理可以直接促进视觉纹理和材料的情感评价的观点。
