Executive functioning and judgment-of-learning versus feeling-of-knowing in older adults.

Feeling-of-knowing (FOK) accuracy and judgment-of-learning (JOL) accuracy were compared on separate, identical, episodic-memory tasks. The results indicated that these two measures were not correlated, suggesting that they do not tap the same metacognitive ability. We also looked at whether FOK and JOL accuracies were related differently to higher order executive functioning. In order to take advantage of within-subject variability in cognitive performance, older adults were selected as participants. They were administered the standard neuropsychological tests used to assess executive functioning. A correlational analysis clearly showed that only FOK accuracy was correlated with the executive measures, suggesting that executive control is not equally implicated in FOK and JOL.
