The influence of averaging and noisy decision strategies on the recognition memory ROC

Many single- and dual-process models of recognition memory predict that the ratings and remember-know receiver operating characteristics (ROCS) are the same, but Rotello, MaCmillan, amd reeder (2004) reported that the slopes of the remember-know and ratings z-transformed ROCs (zROCS) are different. The authors show that the averaging introduces nonlinearities to the form of the zROC and that ratings and remember-know zRoCs are indistinguishable when constructed in a conventional manner. The authors show, further that some nonoptimal decision strategies have a distinctive, nonlinear effect continuous-state zROC. on the form of the single-process co of zRoCs, The conclusion is that manY factors having nothing to do with the nature of recognition memorY can affect the shape of zROCs and that therefore, the shape of the zROC does not, alone, characterize different memory models.
