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.</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}

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.

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 uniformity illusion generally occurs after prolonged central fixation. The uniformity illusion thus seems to evoke illusory peripheral perceptions of colour, shape, size, and even movement. This could be the result of a passive process where the periphery is unattended and ignored, resulting in erroneous reporting of peripheral stimulus properties. The current experiment, however, points to an active filling-in process that resulted in an actual percept of the periphery by showing that the illusory periphery is “sticky”: Even after the central stimuli inducing the illusion were removed, the peripheral illusion persisted, and continued to influence perceptual reports of the participants. Participants viewed displays featuring colour or size variations between the center and periphery for a set time to induce the uniformity illusion, reporting if they experienced a uniform screen. Subsequently, the central patch was altered to match the original periphery, creating a truly uniform display. Participants then evaluated whether the new display appeared uniform and reproduced the size or colour of the peripheral texture. Reaction time and reproduction accuracy revealed that experiencing an illusory periphery interfered with processing subsequent physical stimuli, especially in trials where participants explicitly reported the illusion. These findings suggest that the uniformity illusion can produce a persistent illusory periphery, which disrupts the perception of the actual peripheral stimulus even seconds after the original display has been modified.

Participants performed a memory-based change detection task that contained distractors in a separate display in one block but no distractors in the other block. During the retention interval, a small probe dot would appear unpredictably on a small number of trials, and the task was to detect the dot as quickly as possible. Only the participants who started with the distractor-absent block responded to the dot faster in the distractor-present block than in the distractor-absent block, thus showing the PE. Moreover, the PE was comparable regardless of whether the dot in the distractor-present block appeared at an expected distractor location or an expected empty location (Experiment 1), or whether the dot occurred before, during, or after the expected distractor onset (Experiment 2). In contrast, for the participants who performed the distractor-present block first, a reversed PE was found when the onset of the dot was 400 ms before the onset of the expected distractors. These results indicate that participants normally adopt a “process-all” approach with attention diffusely distributed within a relatively long temporal window.
