Measuring memory factors in source monitoring: Reply to Kinchla.

D. A. Kinchla (see record 1994-16291-001) criticizes W. H. Batchelder and D. M. Reifer's multinomial model for source monitoring, primarily its high-threshold assumptions, and advocates an approach based on statistical decision theory (SDT). The authors lay out some of the considerations that led to their model and then raise some specific concerns with Kinchla's critique. The authors point out that most of his criticisms are drawn from contrasting the high threshold and the Gaussian, equal-variance SDT models on receiver operating characteristics (ROC) curves for yes-no recognition memory. The authors indicate how source monitioring is more complicated than yes-no recognition and question the validity of standard ROC analyses in source monitoring. The authors argue that their model is a good approximation for measuring differences between sources on old-new detection and that it has the ability to measure source discrimination as well as detection. The authors also explore a low-threshold multinomial model and discuss the application of SDT models to source monitoring. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
