The development of metamemory monitoring during retrieval: The case of memory strength and memory absence

This research examined the development of the ability to monitor memory strength and memory absence at retrieval. In two experiments, 7-year-olds, 10-year-olds, and adults enacted and imagined enacting a series of bizarre and common actions. Two weeks later, they completed a memory test in which they were asked to determine whether each action had been enacted, had been imagined, or was novel and to provide a confidence judgment for each response. Results showed that participants across age groups successfully monitored differences in strength between memories for enacted actions and memories for imagined actions. However, compared with 10-year-olds and adults, 7-year-olds exhibited deficits in monitoring of differences in memory strength among imagined actions as well as deficits in monitoring memory absence. Results underscore metamemory developments that have important implications for memory accuracy.
