“…Some authors reported positive effects of item repeti tion on memory performance [18][19][20][21][22], while others did not [23][24][25][26][27][28]. These inconsistencies might be explained by low effect sizes and different, often small samples.…”

The present study is part of a series of systematic studies intended to identify simple strategies of picture presentation to improve recall performance in demented subjects. The aims of this design were to examine the effects of elaboration by naming, 4-fold repetition and different inspection times on memory performance. 19 patients with senile dementia of Alzheimer type and 21 control subjects with remitted depression were included. Picture recall was examined using different presentation conditions on 5 consecutive days. The presentation conditions significantly influenced recall performance depending on the diagnosis and on the delay of recall. Naming of pictures did not improve later recall or recognition. In both groups repetition improved memory performance. Shorter presentation times deteriorated immediate and delayed memory performance in comparison with the control condition. Forgetting did not depend on picture inspection times in patients and control. This observation allows the use of different presentation times for further comparisons of interventions in patients and control. Even though we could provide evidence of some minor memory improvements after some interventions, i.e. prolonged inspection time and repetition, we suppose that the cognitive reserve capacity in demented subjects is limited and does not allow major memory improvements.

“…Studies evaluating memory improve ment strategies in Alzheimer patients were hampered by differences in the severity of memory impairment, by variable perturbations of other cognitive functions, and by spontaneous deteriorations [2]. Consequently, intrain dividual comparisons might be more effective than between-group comparisons for the evaluation of different strategies [3].…”

The study was aimed at estimating the effect size of practice, retention interval and dementia severity on free recall performance in Alzheimer patients. Patients met DSM-III-R criteria for dementia of Alzheimer type. Different picture sets were presented on 4 days. The forgetting curves on different days were compared using ANOVA for repeated measurements. Practice had a minor, but significant negative effect on recall performance explaining 1% of the variance in recall performance. The retention interval varied between zero and 24 h explaining 23% of the total variance. Dementia severity explained 52% of the variance. For the development of memory improvement strategies in Alzheimer patients, the repeated measurement design using intraindividual comparisons seems more powerful than group comparisons.

“…However, in patients with DAT repetition showed inconsistent results: while several authors reported positive eects (Landauer and Bjork, 1978;Schacter et al, 1985;Glisky and Schacter, 1987;Knopman and Nissen, 1987;Shimamura et al, 1987), this was not con®rmed by others (Weingartner et al, 1982;Strauss et al, 1985;Moscovitch et al, 1986;Duchek et al, 1991;Herlitz et al, 1992). The con¯icting results may be due to dierences in the applied repetition conditions or, alternatively, to low eect sizes and therefore to low statistical power.…”

“…In contrast, some authors have reported that forgetting is not accelerated in DAT; these ®ndings, however, remain controversial (Hart et al, 1987;Kopelman, 1985;Freed et al, 1989). Consequently, memory improvement strategies should improve encoding or retrieval Herlitz et al, 1992). Since retrieval conditions are variable under everyday circumstances and can thus not be suciently in¯uenced, interventions during encoding may be preferable.…”
