"WebAug 14, 2024 · The term “sensitivity” is used in two different ways: 1. Mainly in the medical literature, sensitivity is the same as Hit Rate. 2. In SDT, sensitivity corresponds to discriminability, i.e., d′ = z(Hit) − z(FA). We will use the term discriminability rather than sensitivity in the context of SDT.
