Dynamic-static color vision test-DSCVT
Abstract:
As part of the research, a computer-based color vision test-DSCVT-was developed, enabling the assessment of color vision using stimulus with static and dynamic luminance contrast noise. Comparing the DSCVT test results to the anomaloscope and CAD tests, the static stimulus version of the DSCVT test demonstrated 100% sensitivity and 82% specificity, while the dynamic test stimulus version achieved 100% sensitivity and specificity. Chromatic sensitivity changes during a lifetime were examined with both DSCVT and CAD tests. Furthermore, when comparing the chromatic thresholds of normal trichromats measured with both DSCVT test stimulus versions, higher chromatic thresholds were observed with the dynamic version compared to the static version. Additionally, statistically significant differences were found in the chromatic thresholds of anomalous trichromats between the two DSCVT test stimulus modifications, although the results are not conclusive due to the small number of participants with color vision deficits.

Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...
