title: On the validity of remember-know judgments: evidence from think aloud protocols.
abstract: The use of remember-know judgments to assess subjective experience associated with memory retrieval, or as measures of recollection and familiarity processes, has been controversial. In the current study we had participants think aloud during study and provide verbal reports at test for remember-know and confidence (i.e., sure-probably) judgments. Results indicated that the vast majority of remember judgments for studied items were associated with recollection from study (87%), but this correspondence was less likely for high-confidence judgments (72%). Instead, high-confidence judgments were more likely than remember judgments to be associated with incorrect recollection and a lack of recollection. Know judgments were typically associated with a lack of recollection (62%), but still included recollection from the study context (33%). Thus, although remember judgments provided fairly accurate assessments of retrieval including contextual details, know judgments did not provide accurate assessments of retrieval lacking contextual details.
