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.

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.

Specifically, we examined whether patterns of impaired stereopsis across the central 20° of the visual field were accompanied by impaired fusional vergence for stimuli confined to these regions. Stereopsis was measured locally across the visual field with disparity steps of 5 to 20 arcmin. Fusional vergence to large disparity steps (2 to 3°) was measured with binocular eye tracking. The vergence stimuli were random dot stereograms, in one of 3 spatial configurations: a large disc 16° in diameter, a small disc 4° in diameter, and an annulus with outer and inner diameters corresponding to the large and small discs. Of the controls (n = 25) with no history of abnormal visual development, 12 individuals exhibited normal stereopsis across the visual field and normal vergence gains for all configurations. Thirteen individuals with weak stereopsis in the central field tended to have anomalous vergence for small stimuli, but normal vergence for larger stimuli. Amblyopic/strabismic individuals (n = 12) had poor stereopsis and poor vergence for small stimuli.

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.</div></div>","PeriodicalId":23670,"journal":{"name":"Vision Research","volume":"237 ","pages":"Article 108700"},"PeriodicalIF":1.4,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145092696","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}

We compared segmentation thresholds for two kinds of second-order boundaries comprised of two species of micropatterns (e.g., horizontal and vertical Gabors): (1) <em>Feature boundaries</em>, with the same number of total micropatterns on opposite sides but different numbers of each micropattern species within each side, and (2) <em>Density boundaries</em>, 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 <em>late-pooling</em> 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, <em>early-pooling</em> 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.</div></div>","PeriodicalId":23670,"journal":{"name":"Vision Research","volume":"237 ","pages":"Article 108695"},"PeriodicalIF":1.4,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145060599","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}
