Receiver operating characteristics are used to examine the relationship between hits and false alarm rates across changes in response criterion. Dissociations between slope and intercept measures in zROCs have indicated that item recognition requires no less than two functionally independent memory components or processes. In addition, ROC methods have been used to test competing memory models and to uncover the nature of the memory signals underlying various memory tasks.


ROC analysis has also been used to help understand the processes involved in tasks like the remember/know procedure, the process dissociation procedure, and relational recognition tasks. In addition, it has been useful in understanding the memory changes associated with a wide variety of neurological and psychiatric disorders, and it has been applied in studies of rats to understand the effects of hippocampal damage on recognition.
