The amblyopic eye, with reduced visual acuity, has limited ability to compete for perceptual dominance with the non-amblyopic fellow eye during binocular rivalry, likely due to diminished excitatory input or active central foveal suppression. This study investigated whether enhancing the visibility of the amblyopic eye, by increasing stimulus contrast or enlarging stimulus size, could help restore binocular rivalry in adults with anisometropic amblyopia. Using a standard binocular rivalry paradigm, we manipulated the contrast presented to the amblyopic eye and the size of rival stimuli. Results showed that the amblyopic eye exhibited little or no perceptual dominance at smaller stimulus sizes under an equal contrast condition, but dominance increased with larger stimulus sizes and increased contrast, while reducing fellow-eye dominance. However, overall perceptual dominance of the amblyopic eye remained substantially lower than that of the fellow eye and of normal-vision observers, even with enlarged stimuli or high contrast. We found no significant correlation between the fellow-eye dominance bias and the depth of amblyopia, stereoacuity, or interocular suppression in this cohort. Interestingly, individuals with amblyopia showed a much higher proportion of mixed perception compared to normal-vision observers, suggesting qualitatively altered interocular interactions in adults with anisometropic amblyopia. Nevertheless, these findings indicate that increasing the visibility of the amblyopic eye can partially restore its perceptual dominance, offering new insights into the mechanisms of suppression in amblyopia and suggesting potential directions for developing treatment strategies that target binocular vision.

视力下降的弱视眼在双眼竞争中与非弱视眼竞争知觉优势的能力有限，可能是由于兴奋性输入减少或中央中央凹抑制活跃。本研究探讨了通过增加刺激对比度或增大刺激大小来增强弱视眼的可见度是否有助于恢复成人屈光参差性弱视的双眼竞争。使用标准的双眼竞争范式，我们操纵呈现给弱视眼的对比度和竞争刺激的大小。结果表明，在等对比度条件下，弱视眼在较小的刺激尺寸下几乎不表现知觉优势，但随着刺激尺寸的增大和对比度的增大，优势增强，而同眼优势减弱。然而，即使在放大刺激或高对比度的情况下，弱视眼的整体知觉优势仍然明显低于同眼和正常视力的观察者。在这个队列中，我们发现同眼优势偏差与弱视深度、立体视敏度或眼间抑制之间没有显著的相关性。有趣的是，与视力正常的人相比，弱视患者的混合知觉比例要高得多，这表明成人参差性弱视患者的眼间相互作用发生了质的改变。然而，这些发现表明，增加弱视眼的可见度可以部分恢复其知觉优势，为弱视抑制机制提供了新的见解，并为开发针对双目视力的治疗策略提供了潜在的方向。

Peripheral crowding is the difficulty in recognizing objects in cluttered peripheral vision, affecting tasks like reading, visual search, and driving. The luminance of the environment also plays a significant role in these tasks. However, the potential interaction between crowding and luminance is still not clear. This study examined peripheral crowding (10 deg) by measuring its magnitude and critical spacing across a wide range of luminance levels, spanning from scotopic to photopic conditions. Ten participants binocularly identified the orientation of a target presented alone or flanked by four flankers. Responses were made by adjusting a central reference stimulus. Luminance was manipulated using neutral-density filter goggles (0.02–200 cd/m²). The distribution of differences between reported and actual target orientations was obtained, and the standard deviation of these distributions was taken as the perceptual error for each condition. Crowding magnitude was calculated by dividing perceptual error in the flanked condition by that in the isolated condition. Critical spacing was defined as the maximum separation between target and flanker for crowding to occur. It was calculated by fitting a hinged-line to the perceptual errors as a function of target-flanker-distance. Crowding magnitude and critical spacing were both measured for flankers with either no gap, a gap with a size matching each individual’s luminance-specific acuity threshold, or a suprathreshold (200 % of worst-acuity) gap. Results showed that both crowding magnitude and critical spacing were similar under all luminance and gap conditions. Our findings suggest that the same peripheral crowding mechanisms operate under scotopic and photopic conditions.

周边拥挤是指在杂乱的周边视觉中难以识别物体，影响阅读、视觉搜索和驾驶等任务。环境的亮度在这些任务中也起着重要的作用。然而，拥挤度和亮度之间潜在的相互作用仍不清楚。本研究通过测量其大小和临界间距来检查外围拥挤（10度），在广泛的亮度水平范围内，从暗性到光性条件。10名参与者用双眼识别单独呈现或被4个侧翼者包围的目标的方向。反应是通过调节中心参考刺激而产生的。采用中性密度滤光镜（0.02 ~ 200 cd/m2）控制亮度。得到报告目标方位与实际目标方位的差异分布，并将这些分布的标准差作为每种情况下的感知误差。通过将侧翼条件下的感知误差除以孤立条件下的感知误差来计算拥挤程度。临界间距定义为导致拥挤发生的目标与侧卫之间的最大距离。通过将感知误差拟合为目标-侧翼-距离的函数来计算。拥挤程度和临界间距都被测量为没有间隙，尺寸与每个个体的亮度特定锐度阈值匹配的间隙，或超过阈值（最差锐度的200%）间隙的侧翼。结果表明，在所有亮度和间隙条件下，拥挤程度和临界间距相似。我们的研究结果表明，相同的外周拥挤机制在暗光和光条件下运作。

Eye movements have long been used as a measure of underlying brain function and pathology. Specifically, rebound nystagmus has provided a behavioral window into the adaptive mechanisms of gaze holding. It is an eye movement aftereffect resulting from maintaining gaze eccentrically for a prolonged duration. Upon returning to central fixation, the eyes drift or “rebound” back toward the previously held gaze location, demonstrating an adaptive process. Little is known about how prolonged eccentric gaze holding, and the accompanying adaptation of the oculomotor system, influences the perception of visual space. Here, we used a variant of the landmark task to assess spatial bias (or lack thereof) with and without prior eccentric gaze holding. We found that perceived spatial bias after prolonged eccentric gaze holding was significantly different between gaze holding to the far left (−40 deg) and the far right (+40 deg). We also found that sensitivity in distinguishing relative distances between objects in space was marginally different between the left and right gaze holding conditions. This suggests that perceived visual space is differentially impacted by where gaze was previously held, reflecting a dependence on the history of eye positions.

长期以来，眼球运动一直被用来衡量潜在的大脑功能和病理。具体来说，反跳性眼球震颤为研究凝视的适应机制提供了一个行为窗口。这是一种眼动后遗症，是由于长时间保持偏心凝视而引起的。在回到中心注视时，眼睛会漂移或“反弹”回到先前的注视位置，这表明了一个适应过程。对于长时间的偏心凝视以及伴随的眼球运动系统的适应如何影响视觉空间的感知，我们知之甚少。在这里，我们使用了一个里程碑任务的变体来评估空间偏差（或缺乏空间偏差），无论是否事先偏心凝视。我们发现，长时间偏心凝视后的感知空间偏差在凝视极左（-40度）和极右（+40度）之间存在显著差异。我们还发现，在左凝视和右凝视的条件下，区分空间中物体之间相对距离的敏感度略有不同。这表明，被感知的视觉空间受到先前凝视位置的不同影响，反映了对眼睛位置历史的依赖。

Color vision is vital for animal survival, essential for foraging and predator detection. In mice, as in other mammals, color vision originates in the retina, where photoreceptor signals are processed by neural circuits. However, retinal responses to stimuli involving multiple colors are still not well understood. One possible explanation of this knowledge gap is that previous studies have not thoroughly examined how neuronal activity adapts to a 30 s to a few minutes timescale when exposed to multiple color sources. To address this, we systematically varied the UV-to-green light balance with a custom-built stimulator targeting mice opsins spectra while recording retinal ganglion cell responses across the dorso-ventral axis of the retina using multielectrode arrays. Responses to full-field chirp and checkerboard stimulations with alternating UV and green light revealed that more than one order of magnitude of intensity difference favoring green M-opsin over UV S-opsin is needed for a balanced reliability in retinal ganglion cell responses in the ventral retina. An incorrect balance, with slightly increased UV light, silenced responses to green illumination. To determine if these values are consistent with natural conditions, we analyzed isomerisation rates in the mouse retina across different times of the day. We found that the M- to S-opsin activation ratio remains constant through the mesopic-photopic range, and that our empirically determined values in the ventral retina align well with these natural conditions. These lie far from a simple equalization of M- and S-opsin isomerisation rates, which we found only balances ganglion cell responses in the dorsal retina. In conclusion, a finely tuned color intensity balance matching natural light spectrum is essential for accurately measuring both fast temporal responses and detailed spatial receptive fields in the ventral retina.

色觉对动物的生存至关重要，对觅食和发现捕食者至关重要。和其他哺乳动物一样，老鼠的色觉起源于视网膜，视网膜上的感光信号由神经回路处理。然而，视网膜对涉及多种颜色的刺激的反应仍然没有得到很好的理解。对这种知识差距的一种可能解释是，以前的研究并没有彻底研究当暴露于多种颜色源时，神经元活动如何适应30秒到几分钟的时间尺度。为了解决这个问题，我们系统地使用定制的针对小鼠视蛋白光谱的刺激器来改变紫外光与绿光的平衡，同时使用多电极阵列记录视网膜背-腹侧轴的视网膜神经节细胞反应。对紫外和绿光交替的全场啁啾和棋盘刺激的反应表明，在腹侧视网膜神经节细胞反应中，需要一个数量级以上的强度差异，以支持绿色m -视蛋白而不是紫外s -视蛋白。一个不正确的平衡，稍微增加紫外线，沉默的绿色照明的反应。为了确定这些值是否与自然条件一致，我们分析了一天中不同时间小鼠视网膜的异构化率。我们发现M- to - s -视蛋白激活比在中视-光位范围内保持不变，并且我们在腹侧视网膜中确定的经验值与这些自然条件很好地吻合。这些远不是M-和s -视蛋白异构化率的简单均衡，我们发现这只是平衡视网膜背侧神经节细胞的反应。总之，与自然光谱相匹配的色彩强度平衡对于准确测量腹侧视网膜的快速时间反应和详细的空间感受野是必不可少的。

Processes of perceptual segmentation and integration (PSI) are fundamental to perceptual organization. Although PSI of visual stimuli has been studied for over a century, we have only a rudimentary understanding of PSI of natural visual stimuli. This is due to limitations of traditional experimental methods in visual psychophysics of PSI; to the exclusive focus of computer-vision research for image segmentation on performance benchmarks; and to the scarcity of meaningful interactions between those two communities. The recent literature discussed in this paper presents a compelling argument that the field is starting to overcome those barriers. One important example of such an interaction between visual psychophysics and machine learning is given by the literature on the crowding phenomenon, which calls for revised models of summary statistics to explain some uncrowding results. Other examples reviewed here include studies of the perceptual uncertainty and dynamics of segmentation of natural stimuli, which call for computational models with probabilistic representations and dynamic computations. Conversely, contemporary machine learning algorithms produce impressive segmentation maps that still need to be aligned with human maps as measured with objective tasks such as the same/different segment paradigm reviewed here. Therefore, the time is ripe to move vision science forward by bridging new computational and experimental paradigms for PSI of natural stimuli.

知觉分割与整合过程是知觉组织的基础。虽然视觉刺激的PSI研究已经进行了一个多世纪，但我们对自然视觉刺激的PSI只有初步的了解。这是由于传统的视觉心理物理实验方法的局限性；以计算机视觉研究的独家焦点为图像分割的性能基准；以及这两个群体之间缺乏有意义的互动。本文中讨论的最新文献提出了一个令人信服的论点，即该领域正在开始克服这些障碍。关于拥挤现象的文献给出了视觉心理物理学和机器学习之间这种相互作用的一个重要例子，它要求修订汇总统计模型来解释一些非拥挤结果。这里回顾的其他例子包括对自然刺激的感知不确定性和动态分割的研究，这需要具有概率表示和动态计算的计算模型。相反，当代机器学习算法产生了令人印象深刻的分割地图，但仍然需要与人类地图保持一致，以客观任务（如本文回顾的相同/不同分段范式）进行测量。因此，通过连接自然刺激的PSI的新计算和实验范例，推动视觉科学向前发展的时机已经成熟。

Stereoacuity, the ability to perceive depth from binocular disparity, is traditionally considered to be best at the fovea in typical human vision, and to decline with eccentricity. Previous studies have shown that when stereopsis is present in amblyopia, it is often coarse and comparable to stereoacuity associated with the peripheral retina in neurotypical controls, suggesting that it might be mediated by a non-foveal locus. Here we measured stereoacuity as a function of eccentricity in participants with amblyopia as well as controls with no history of abnormal visual development. We measured stereoacuity using random dot stereograms and targets that scaled with eccentricity, testing the fovea, and eccentricities of 2.5°, 5°, and 10° along the horizontal and vertical meridians. For 87.5% (7/8) of amblyopic participants, the locus of best stereoacuity was non-foveal. Surprisingly, 75% of control participants (15/20) also exhibited their best stereoacuity at non-foveal locations, with only 5 controls showing foveal superiority. Using stimulus parameters modified to improve foveal performance, we repeated measurements on a subset of controls whose best stereoacuity was non-foveal, but the best locus only shifted to the fovea in one participant. Stereoacuity measured at the experimentally determined “best locus” correlated well with standard clinical stereoacuity tests. These findings challenge the conventional view of universal foveal dominance for stereopsis, suggesting that the fovea is not invariably the site of best stereoscopic sensitivity, even in many normally sighted individuals. This has implications for understanding binocular vision in amblyopic and normal vision, and for interpreting clinical stereo tests.

立体敏锐度，即从双眼视差中感知深度的能力，传统上被认为在典型的人类视觉中，中央凹是最好的，而随着偏心而下降。先前的研究表明，当弱视存在立体视时，它通常是粗糙的，与神经典型对照中与周围视网膜相关的立体视敏相当，这表明它可能是由非中央凹位点介导的。在这里，我们测量了立体敏锐度作为偏心的功能，在弱视参与者和对照组没有视觉发育异常的历史。我们使用随机点立体图和按偏心比例缩放的目标来测量立体敏锐度，测试中央凹，以及沿水平和垂直子午线的2.5°，5°和10°的偏心。在87.5%（7/8）的弱视参与者中，最佳立体视敏位置为非中央凹。令人惊讶的是，75%的对照组参与者（15/20）在非中央凹位置也表现出最佳立体视力，只有5个对照组显示出中央凹优势。通过修改刺激参数来提高中央凹的表现，我们对非中央凹的最佳立体视敏度的控制组进行了重复测量，但只有一名参与者的最佳立体视敏度转移到了中央凹。在实验确定的“最佳位置”测量的立体视敏度与标准的临床立体视敏度测试有很好的相关性。这些发现挑战了关于立体视觉的中央凹优势的传统观点，表明即使在许多正常视力的个体中，中央凹也不一定是最佳立体敏感度的位置。这对理解弱视和正常视力的双眼视觉，以及解释临床立体测试具有重要意义。

These findings challenge the conventional view of universal foveal dominance for stereopsis, suggesting that the fovea is not invariably the site of best stereoscopic sensitivity, even in many normally sighted individuals. This has implications for understanding binocular vision in amblyopic and normal vision, and for interpreting clinical stereo tests.</div></div>","PeriodicalId":23670,"journal":{"name":"Vision Research","volume":"240 ","pages":"Article 108748"},"PeriodicalIF":1.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145811284","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}

There is a lack of validated clinical tools to measure visual functions in children with cerebral visual impairment (CVI). This study addresses this gap. Children aged 6 months-7 years with and without CVI (CVI, n = 111, mean age: 3.0 ± 1.9 years; 70.2 % male and without CVI, n = 50, mean age: 3.4 ± 1.9 years; 38 % male) were recruited. Grating acuity (GA) was evaluated using Teller Acuity Cards-II (TAC-II) and the Peekaboo Vision app (PV app), and contrast sensitivity (CS) using Hiding Heidi low contrast face cards (HH cards) and Ohio Contrast Cards (OCC). Retests were conducted within one month. The mean difference between the PV app and TAC-II was significant (CVI: −0.25 ± 0.40 logMAR, 95 % LoA: −1.03 to 0.53 logMAR; controls: −0.14 ± 0.30 logMAR, 95 % LoA: −0.72 to 0.44 logMAR). The median difference between the HH cards and OCC was also significant (CVI: 0.00 logCS, IQR: 0.25 logCS, 95 % LoA: −0.43 to 0.67 logCS; controls: 0.25 logCS, IQR: 0.00 logCS, 95 % LoA: −0.01 to 0.56 logCS). Intra-examiner repeatability analysis in children with CVI (n = 21) and controls (n = 16) revealed that TAC-II (CR, CVI = 0.47, controls = 0.27) had better repeatability than the PV app (CR, CVI = 0.99, controls = 0.41), while OCC (CR, CVI = 0.45, controls = 0.19) had better repeatability than HH cards (CR, CVI = 0.90, controls = 0.60). TAC-II and OCC demonstrated better repeatability and comparable testability, testing time, and engagement scores for GA and CS tests respectively in children with CVI. Findings indicate that clinical tools should not be used interchangeably, and clinicians must carefully interpret results based on each test’s repeatability indices.

目前缺乏有效的临床工具来测量脑性视觉障碍（CVI）儿童的视觉功能。这项研究解决了这一差距。纳入6个月~ 7岁伴有和不伴有CVI的儿童（CVI, n = 111，平均年龄：3.0±1.9岁；70.2%为男性，n = 50，平均年龄：3.4±1.9岁；38%为男性）。光栅灵敏度（GA）使用Teller acuity cards - ii （TAC-II）和Peekaboo Vision应用程序（PV app）进行评估，对比度灵敏度（CS）使用hidden Heidi低对比度人脸卡（HH cards）和Ohio contrast cards （OCC）进行评估。在一个月内进行了重新测试。PV应用程序和TAC-II之间的平均差异显著（CVI:−0.25±0.40 logMAR, 95% LoA:−1.03至0.53 logMAR；对照组：−0.14±0.30 logMAR, 95% LoA:−0.72至0.44 logMAR）。HH卡和OCC之间的中位数差异也很显著（CVI: 0.00 logCS, IQR: 0.25 logCS, 95% LoA: - 0.43至0.67 logCS；对照组：0.25 logCS, IQR: 0.00 logCS, 95% LoA: - 0.01至0.56 logCS）。对CVI患儿（n = 21）和对照组（n = 16）的重复性分析显示，taci - ii （CR, CVI = 0.47，对照组= 0.27）的重复性优于PV应用程序（CR, CVI = 0.99，对照组= 0.41），OCC （CR, CVI = 0.45，对照组= 0.19）的重复性优于HH卡（CR, CVI = 0.90，对照组= 0.60）。在CVI患儿中，TAC-II和OCC在GA和CS测试中分别表现出更好的可重复性和可比性、测试时间和参与得分。研究结果表明，临床工具不应互换使用，临床医生必须根据每个测试的可重复性指标仔细解释结果。

Patients who develop difficulties in orienting in familiar environments have been well-described in neurology and neuropsychology. This topographical disorientation, when it occurs, follows damage to occipitotemporal regions of the brain. The lesions are often bilateral, but when they are one-sided, disorientation is much more likely to follow from damage to the right hemisphere. However, the evidence from the neuroimaging literature on scene perception and spatial navigation rarely refers to cerebral dominance favoring the right hemisphere. This contradiction is in part explained by how threshold-dependent methods in neuroimaging are often not well suited for visualizing let alone quantifying brain asymmetry. In the present investigation, brain asymmetries for scene perception are quantified in a large sample, enriched with non-right-handed participants who are more heterogeneous for brain asymmetries. Results show a weak but consistent right hemispheric bias. A planned region of interest analysis provided only weak support for models of differential lateralization of perceptual and semantic nodes within the scene network. Surprisingly, right dominance was most prominent in retrosplenial cortex, contrary to models that suggest it functions in semantic/mnemonic rather than perceptual domains. Results are discussed in terms of the utility of such an approach for elucidating the functional nature of different scene network subregions, and how publicly-available datasets will prove exceptionally useful for doing so.

在神经病学和神经心理学中，对在熟悉环境中出现定向困难的患者进行了很好的描述。这种地形定向障碍，当它发生时，是随着大脑枕颞区的损伤而发生的。病变通常是双侧的，但当病变是单侧的，定向障碍更可能是右半球损伤引起的。然而，关于场景感知和空间导航的神经影像学文献证据很少涉及大脑的右半球优势。这种矛盾在一定程度上可以解释为神经成像中依赖阈值的方法通常不太适合可视化，更不用说量化大脑的不对称性了。在本研究中，我们在一个大样本中量化了场景感知的大脑不对称，丰富了非右撇子参与者，他们在大脑不对称方面更具异质性。结果显示轻微但一致的右半球偏倚。计划的兴趣区域分析仅为场景网络中感知和语义节点的差异侧化模型提供了微弱的支持。令人惊讶的是，右主导权在脾后皮层最为突出，这与认为它在语义/助记而不是感知领域起作用的模型相反。结果讨论了这种方法在阐明不同场景网络子区域的功能性质方面的效用，以及如何公开可用的数据集将证明对这样做非常有用。

Although poor monocular visual acuity is the main characteristic of amblyopia, binocular vision is also often disrupted in amblyopia. Motion perception deficits have also been reported to be impaired in both amblyopic and fellow eyes. Occlusion therapy, the gold-standard treatment for amblyopia, is usually unsuccessful at fully restoring binocular visual function or motion perception. We evaluated the effectiveness of a video game-based dichoptic treatment (Vivid Vision) for restoring these aspects of vision in amblyopia. Twenty-one participants (age 6 to 56 years) with strabismic, anisometropic or aniso-strabismic amblyopia were assessed before and after 8 weeks of binocular treatment. Treatment was not part of the research protocol and comprised at least 4 h of training through a local optometry practice in the clinic or at home. Monocular visual function measures included visual acuity, and coherence thresholds for discriminating motion-defined form orientation or global motion direction. Binocular measures included stereoacuity and interocular suppression measured as a contrast balance index on a dichoptic eye chart. Group analyses revealed abnormal performance before the treatment, relative to a large control dataset (N = 217), on every measure except fellow-eye visual acuity. After the treatment, there was a significant mean improvement in amblyopic-eye visual acuity, amblyopic-eye motion-defined form perception and fellow-eye global motion perception, with some participants improving to normal performance levels. Interocular suppression was reduced in 43 % of participants and stereoacuity improved in 14 % of participants following treatment. Visual acuity improvement was greater with clinic than home-based treatment, while global motion improvement was greater in the strabismic amblyopic group. There was no effect of participant age. The Vivid Vision dichoptic treatment improved monocular and binocular measures in some but not all participants.

虽然单眼视力差是弱视的主要特征，但双眼视力也经常受到影响。运动知觉缺陷也被报道在弱视和其他眼睛受损。遮挡治疗是治疗弱视的黄金标准，但通常不能完全恢复双眼视觉功能或运动知觉。我们评估了以视频游戏为基础的二分视治疗（生动视觉）对恢复弱视患者这些方面视力的有效性。21名患有斜视、屈光参差或屈光参差性弱视的参与者（6至56岁）在双眼治疗8周前后进行了评估。治疗不是研究方案的一部分，包括至少4小时的当地诊所或家庭验光培训。单眼视觉功能测量包括视敏度，以及区分运动定义的形式方向或整体运动方向的相干阈值。双眼测量包括立体视敏度和眼间抑制，在双视视力表上测量对比度平衡指数。组分析显示，相对于大型对照数据集（N = 217），治疗前除同眼视力外，其他各项指标均表现异常。治疗后，弱视视敏度、弱视运动定义形态感知和同眼整体运动感知均有显著改善，部分参与者的表现水平改善至正常水平。治疗后，43%的参与者眼间抑制减少，14%的参与者立体视力改善。临床治疗比家庭治疗的视力改善更大，而斜视弱视组的整体运动改善更大。没有受试者年龄的影响。生动视觉治疗改善了部分参与者的单眼和双眼测量，但不是所有参与者。
