Model for Visual Luminance Discrimination and Flicker Detection
Abstract
A model for vision is proposed. Its basic units are RC stages whose time constants—in three instances—are parametrically controlled. The requirements of compressing the dynamic range of the input and of fitting luminance pulse-detection data suffice to determine the arrangement and parameters of the components. This model accurately predicts the psychophysical results of flicker detection (DeLange characteristics at above 10 Hz), the Ferry–Porter and Weber laws in the ranges where they apply, the effects of light adaptation, and it accounts for individual differences. By considering the variable RC stage as an approximate analog of a synaptic excitatory process which is controlled by inhibition, significant correspondences are observed between the internal connectivity of the model and the neural connectivity of the retina.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
