Hick-Hyman law: RT = c + d · log₂(N+1); choice-RT scales with information H in bits

Layer 3 — Biologyin the cognitive-neuroscience subtree

Hick-Hyman law — the canonical information-theoretic framework for choice reaction time (CRT) in cognitive neuroscience (Hick 1952 / Hyman 1953). Physical setup: a subject must respond as rapidly as possible to one of N equiprobable…
