In recognition memory experiments, the tendency to identify a test item as “old-or “new-can be increased or decreased by instructions given at test. The effect of such response bias on remember-know judgments is to change “remember-as well as “old-responses. Existing models of the remember-know paradigm (based on dual-process and signal detection theories) interpret this effect as a shift in response criteria, but differ on the nature of the dimension along which the changes take place. We extended the models to account simultaneously for remember-know and confidence rating data and tested them using old-new (Experiment 1) and remember-know (Experiment 2) rating designs. Quantitative fits show that the signal detection models provide the best overall description of the data.
