Relevance of unjustified strong assumptions when utilizing signal detection theory
Published online by Cambridge University Press: 30 January 2004
Abstract:
Several conclusions depend on a version of signal detection theory that assumes performance is based on underlying equal-variance normal distributions of trace strength. Such conclusions are questionable without empirical justification for that assumption. A thought experiment is presented to show how the assumption is probably invalid, and empirical evidence is cited for the assumption's invalidity in research on human memory.
