Abstract

Age differences in metamemory accuracy obtained for episodic memory – new information – compared to semantic memory – general knowledge information were compared in this study. Younger and older adults with no known cognitive impairments viewed pictures of famous faces for semantic memory and nonamous faces for episodic memory. Participants then viewed the faces again and had to provide the name for either semantic or episodic memory. After attempting recall for each face, participants made a Feeling-of-Knowing prediction about future recognition. Finally, each face was presented with the correct answer and three alternative answers. A gamma correlation was used to calculate prediction accuracy. Younger and older adults were equally accurate at predicting their recognition for semantic and episodic memory. The findings demonstrate that using the same materials and a within-subjects design, older adults do not show deficits in metamemory accuracy, even when predicting a type of memory that is typically impaired with age.
