However, these tests differ substantially in the type of visual task, stimulus configuration, vectors, luminance, background composition, and presentation time. This study aimed to compare the evaluation parameters estimated by these tests in trichromatic and dichromatic individuals. A total of sixty-six participants (40 trichromats and 38 dichromat individuals −16 protans and 22 deutans; mean age: 26.3 ± 8.9 years) were evaluated. Color discrimination thresholds were fitted to elliptical functions, and parameters such as ellipse area, rotation angle, and the size of protan, deutan, and tritan vectors were analyzed. Results showed equivalence between the tests for: the deutan and tritan vector areas and sizes in the trichromat subgroup; tritan vector area and size in the protan subgroup; and protan and tritan vector sizes in the deutan subgroup. Differences in the central coordinates of the CAD and CCT tests and the spatial arrangement of vectors in the CIE 1976 color space (specific to the CCT test) may have influenced the results. Nonetheless, agreement was observed in the measures of ellipse area, rotation angle, and sizes of the protan and tritan vectors between the two tests. These findings suggest that, despite methodological differences, the CAD and CCT tests produce largely comparable results and can be considered complementary tools in the assessment of color discrimination in clinical and research settings.</div></div>","PeriodicalId":23670,"journal":{"name":"Vision Research","volume":"235 ","pages":"Article 108664"},"PeriodicalIF":1.5,"publicationDate":"2025-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144704383","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}

In four experiments, we explore whether these results are best explained by a visual similarity account, an attentional zoom account, or a combination of the two. Using a shape comparison task, we manipulated the visual similarity and predictability of the target displays by varying the local position of the target letter, either between different blocks (i.e., predictable; Experiments 1a and 2a) or within a block (i.e., unpredictable; Experiments 1b and 2b); additionally, we varied the distractor letters such that they were the same between the to-be-compared displays in most of the trials (Experiments 1a and 1b) or they were different in every trial (Experiments 2a and 2b). Under conditions of low interference, the predictability of visual information has no effect on the OB, or on the SCB, but this may be because attentional demands are low in these conditions. As predicted by the attentional zoom account, the SCB is influenced by predictability when peripheral interference is high.

While some material property changes of the aging human crystalline lens have been mapped, challenges remain in their in vivo characterization. Conflicting findings in the literature highlight the complexity of accurately defining lens biomechanics. Young’s modulus, anterior and posterior lens curvatures, lens thickness, and refractive index are examples of these well-studied properties. However, knowledge of forces applied to the crystalline lens for generating corresponding accommodative amplitudes has been limited to a few age groups. A full mapping of these accommodative forces over decades for the aging human eye remains incomplete. We used mechanical properties available in the literature to develop a mechanical model of the crystalline lens for age groups between 10 and 70 years. Then, finite element modeling and optical power calculations obtained from lens deformation during simulated accommodation were used to create a map of accommodative forces over the human lifespan. We found an S-curve-shaped decline in total equatorial forces required on the capsule to achieve reported accommodative amplitudes. This decline does not indicate increased lens compliance but reflects the possibility of age-related weakening of the applied force. The total force ranged from 0.5 N at age 10 to near zero at age 70, with a steep drop between ages 30 and 50.</div></div>","PeriodicalId":23670,"journal":{"name":"Vision Research","volume":"235 ","pages":"Article 108657"},"PeriodicalIF":1.5,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144604387","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}

Twenty macular cube scans per eye were acquired with the Cirrus HD-OCT in 30 amblyopes and 30 controls with normal binocular vision. The foveal location was identified with the instrument’s software as line scan coordinates to determine the distance between the fovea and the center of the scan.

Amblyopic eyes demonstrated greater position error and fixation instability compared to fellow and control eyes. Simple linear regressions revealed a significant relationship between both position error and VA and fixation stability and VA. However, with multiple regression, position error alone was the significant predictor of VA.

To address this, we used estimates from the literature of sensitivity for a wide range of distance cues to predict the contribution of pictorial, binocular, and motion cues to relative distance. The cues assessed included convergence, accommodation, height in the field, texture density, relative size, height in the field, binocular disparity, and motion (assuming a walking observer). We used the modified weak fusion model to estimate the contribution of binocular, motion, and pictorial cues for distances between 2 and 100 m.

We also compared a simple virtual environment with a complex virtual environment by creating landscapes. The vergence scores obtained for divergence and convergence with the virtual reality device were very similar to those obtained using prisms. This suggests that the virtual environments efficiently stimulated vision conditions in 3 dimensions. Our results also support the idea that modulating the angular deviation of the projected image in the virtual reality headset is a satisfactory way of inducing ocular vergences. The amplitudes of fusion were better in the virtual conditions, suggesting that the controlled virtual environments provided better conditions for measuring vergence movements. Furthermore, the virtual reality device induced a better amplitude of fusion in participants with high convergence abilities by preventing the underestimation of divergence abilities in these participants.
