Signal-detection theory: d' = z(H) − z(F), c = −(z(H)+z(F))/2

Layer 3 — Biologyin the cognitive-neuroscience subtree

Signal-detection theory (SDT; Green & Swets 1966, Macmillan & Creelman 2005) decomposes performance in any yes/no discrimination task (perceptual, memory, diagnostic) into (a) sensitivity d' — how discriminable the signal is from noise,…
