Quantity- Accuracy Profiles or Type-2 Signal Detection Measures? Similar Methods towards a Common Goal

Abstract

In the previous chapter, Phil Higham follows up on previous work showing how methods based on type-2 signal detection theory (SDT) can be used to study the strategic regulation of memory performance, and compares some of the advantages and disadvantages of this approach to Koriat and Goldsmith’s (1996b) Quantity-Accuracy Profile (QAP) methodology. I am glad to have the opportunity to comment on some of the points made in that chapter. I am also glad to be able to participate in this volume honouring Bruce Whittlesea, who among his many significant contributions to the study of memory, has done much to emphasize the critical role played by post-retrieval evaluation and decision processes in remembering (e.g., Whittlesea, 2002; Whittlesea & Williams, 2001a, 2001b).
