J. T. Wixted argued that nearly every recent study that was designed to differentially test the unequal-variance signal-detection (UVSD) and dual-process signal-detection (DPSD) models has yielded findings that strongly support the UVSD model. C. M. Parks and A. P. Yonelinas did not address these studies in detail and instead focused mainly on issues that are tangential to the debate (e.g., measurement issues and neuroimaging). What few responses they did offer to the more relevant model-comparison studies did not effectively address the difficulties they posed for the DPSD model.
