| Abstract: | Previous research has examined whether Alzheimer's disease (AD) patients can proficiently monitor their memory processing. In the present study we extended the scope of this research to consider confidence in recognition in an episodic memory task, using a forced-choice recognition paradigm to avoid floor effects. AD patients and age-matched controls studied 32 words, followed immediately by a recognition test requiring participants to select the target from pairs of items. Participants rated confidence in their choice on a 3-point scale. Despite significantly poorer memory performance and less confidence overall, gamma correlations indicated that the AD group accurately assigned confidence judgements to their responses. This adds support to the claim that metacognitive monitoring remains intact in AD. |
