Primes¶
- Logarithmic Perception and Encoding
- Psychophysics (Weber/Fechner) — just-noticeable differences are proportional to baseline intensity; subjective magnitude is logarithmic in physical intensity for many channels.
This sourceOriginates the psychophysical law that subjective sensation grows as the logarithm of stimulus intensity, integrating Weber's constant just-noticeable-difference ratio.

Fechner states Weber's law as equal sensation increments for equal relative stimulus increments and gives just-noticeable-difference examples; the explicit logarithmic form is not in the volume held.
“Aequivalent mit dem vorigen Ausspruche sind folgende kürzere Aussprüche: der Empfindungsunterschied, Empfindungszuwuchs bleibt sich gleich, wenn der relative Reizunterschied oder relative Reizzuwuchs sich gleich bleibt”

- Threshold
- Perception research grounds psychophysical thresholds and Weber's law in threshold mechanics, with Fechner (1860) providing the canonical psychophysical synthesis linking just-noticeable differences to absolute and difference limens.
This sourceBreitkopf und Härtel. Founding text of psychophysics: develops absolute and difference thresholds (limens) and their measurement, grounding Weber's law and the broader threshold framework for sensation.

Fechner's Elemente defines the method of just-noticeable differences and separates absolute from difference sensitivity under Weber's law; the limen chapters are not in the cached text.
“Die Methode der eben merk- lichen Unterschiede besteht nun darin, die Grösse des Gewichts- unterschiedes zu bestimmen, welche nöthig ist, um als eben merklich erkannt zu werden.”

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 2 of 2 citations: 2 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.
