Executive functioning and memory as potential mediators of the episodic feeling-of-knowing accuracy.

The study focused on the cognitive determinants of the accuracy of feeling-of-knowing (FOK) judgments made on episodic memory information. An individual differences approach was used on a sample of healthy older adults assessed on an episodic FOK task and on several neuropsychological measures. At a global level of analysis of FOK accuracy, the contributions of four general cognitive processes--episodic memory, executive functioning, fluid intelligence and processing speed--were examined concurrently.

Aging and implementation of encoding strategies in the generation of rhymes: the role of executive functions.

This experiment examines whether the age-related decrease in the generation effect of rhymes is mediated by executive functioning. Young and elderly adults read and generated pairs of rhyming words for subsequent recall. Participants were also administered neuropsychological tests (executive and mnemonic functions).
