We examined patients with Dementia-Alzheimer's Type, depression, and matched controls on tasks designed to compare automatic (monitoring frequency and modality) and effortful (free recall) processing of words and pictures. The results demonstrated that de pressed patients performed poorly only when conditions required effortful processing, but DAT patients performed poorly under all conditions. There was almost no overlap in scores between DAT and elderly depressed patients on one of the measures of automatic processing suggesting that this measure may be clinically useful. The results suggest that automatic memory processes can be partially dissociated from effortful memory processes, but that both types of operations are impaired in DAT patients.
