BACKGROUND: The aim of the present study was to analyse serial position effects for immediate and delayed free recall in @entity1 with @entity303 of the Alzheimer type and controls. EXPERIMENT 1: 44 @entity1 with @entity303 of the Alzheimer-type and 24 non-demented controls were asked for immediate and delayed free recall of 12 schematic drawings of common objects presented at the rate of 10 s/picture. Steep primacy effects were obtained at all delays in controls. By contrast, primacy effects were significantly impaired in @entity1 with @entity303 at all delays of recall. Small immediate and delayed recall recency effects were found in both, @entity1 and controls. EXPERIMENT 2: 19 @entity1 with @entity303 of the Alzheimer type and 21 controls were asked for immediate and delayed free picture recall with presentation rates of 10, 5 and 1 s/picture. Again, primacy effects were significantly impaired in demented @entity1 versus controls. With shorter presentation times, immediate recall recency effects were more pronounced than with longer presentation times, and no delayed recall recency effects were found. CONCLUSIONS: Primacy effect is impaired for immediate and delayed recall in @entity303 of the Alzheimer type. By contrast, immediate recall recency effect and possibly also long-term recency effect are preserved. The loss of the primacy effect contributes to the @entity2414 in @entity303 of the Alzheimer type. Therefore further research is warranted into pharmacological and psychological interventions that might re-establish the primacy effect. Possibly, the orientation of demented @entity1 might be improved by psychological techniques that rely on long-term recency effect.
