This study partially replicates previous findings that Alzheimer's disease (AD) patients overpredict their performance on memory tasks. Higher functioning AD patients generally overpredicted their performance as compared to their caregivers' predictions of the patients' abilities across four memory tasks. There was only one significant difference between the lower functioning AD patients' and their caregivers' predictions of the patients' performance. Higher functioning AD patients had no difficulty in providing estimations of their caregivers' abilities on the same memory tasks, while the lower functioning AD patients generally overestimated their caregivers' performance. The second part of this study evaluated AD patients' performance on two temporal order tasks. There was no significant difference between the patients' and the control subjects' temporal order judgments. Results are discussed in terms of the role of frontal cerebral systems and methodological problems inherent to research with dementia patients.
