Standard d-prime must be modified for time-variable change detection tasks

Evidence

Classical d’ analysis does not apply in the present dynamic decision paradigm, since the eventual outcome of a trial is not accessible at early times (i.e. when computing d’(0.5 s), a trial with a hit at 5 s should not be counted as a hit, but as a ‘correct reject up to 0.5 s; but when computing d’(4 s), the same trial will be counted as a hit). — Dijk, Pim van, Physiology, Psychoacoustics and…, 3285

Categorization

• DEFINE: Explains a methodological subtlety: in dynamic-decision paradigms a single trial counts as different outcomes at different analysis times.
• QUESTION: Worth chasing how a trial-outcome labeling convention biases early-time d’ estimates in time-varying tasks.
