2 citations across 2 artifacts.
Each citation links to the sentence it supports in the citing article.
Domain-specific¶
- Psychophysical Scaling
- They share a genus and retain distinct identities. Not unrestricted extrapolation. A relation established in the central operating range can fail near detection floor, adaptation shifts, pain limits, or physiological saturation
This sourceThe standard methods text for the boundary proposition, documenting that the Weber fraction rises near absolute threshold and that fitted functions depart from the middle-range law at the extremes; the adaptation, pain-limit and saturation clauses of the same sentence lie outside its scope. The standard methods text for both halves - estimating a just-noticeable difference at several baselines, forming the increment-to-baseline ratio as the Weber fraction, and finding that the fraction is approximately constant only over a middle range of intensities.

Mechanisms¶
- Roughness and Relief Gradient
- Its strength is building depth, weight, or emphasis continuously — avoiding the banded, stepped look — by keeping each increment below the just-noticeable difference
This sourceEstablishes that a stimulus change below the just-noticeable difference is not perceptually detectable as a separate increment.

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Read against the text for 1 of 2 citations: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
