| Opplysninger | The evidence for positive effects of repetition on recall performancein patients with dementia of Alzheimer type is equivocal. This may bedue to the difference repetition conditions used. The aim of thisstudy was therefore to evaluate the effects of different repetitionmodes on the improvement of recall performance in demented subjects.Twenty-four patients with Alzheimer type dementia and 24 controlsubjects with remitted depression were included in the study.Pictures were presented repeatedly using different presentation modesat a constant total presentation time. Free recall was testedrepeatedly after different periods of delay (0-8 hours). Immediateand delayed list repetition significantly improved recall performancein both groups. Within-list repetition did not improve total recallin demented subjects. The repeated measurement design sensitivelydetected minor changes in recall performance. These were not observedusing other measures of recall and recognition (hits, false alarms,indices of signal discrimination).
