ABSTRACT
Metacognition has become an important focus of cognitive research. As is often the case, the research began with the investigation of a specific phenomenon, in this case Hart's exploration of the feeling of knowing (FOK). Initial exploration of a phenomenon such as FOK may reflect the interests of a single investigator, but the rapid development of a research area requires a much wider recognition of the potential importance of the domain. Nelson and Narens organized this research domain in their seminal paper that focused on the distinction between monitoring and control processes and described the available techniques of measurement. The purpose of the Bahrick and Phelps investigation was to explore interventions designed to restore recall access to marginal knowledge. The metamemory data are based on three investigations in which extended retention intervals were used. This data also shows that previous investigations may have underestimated the potential validity and generality of metacognitive predictions of long-term retention.
