INCORPORATING RESPONSE BIAS IN A DUAL-PROCESS THEORY OF MEMORY

We examined several different methods for incorporating response bias into a dual-process theory of recognition memory. Two high threshold c orrection methods, which have previously been applied to the process d issociation procedure, and a new, dual-process signal-detection method , were assessed. An examination of receiver operating characteristics (ROCs) showed that the threshold methods were inappropriate, but that the signal-detection method provided a reasonable account of the obser ved ROCs. Applying the corrections to a second data set showed that th e different correction methods led to dramatically different conclusio ns, demonstrating that selecting the correct correction method is crit ical. Moreover, in agreement with the ROC analysis, the signal-detecti on method was the only one to provide a reasonable account of the data . (C) 1995 Academic Press, Inc.
