Sensitivity to Levels of Importance in the Logical Memory Subtest

The performance of Alzheimer's disease (AD) and neuropsychiatric patients was examined using the Logical Memory (LM) subtest of the WMS-R, utilizing a levels of importance methodology described by Haut et al. (1990). Although patient groups were matched for dementia severity, we found the expected differences between groups in terms of absolute level of performance. There was considerable variability, however, in the AD patients' performance. AD patients' recall and sensitivity to levels of importance depended on the story (Anna or Robert), and when the passages were recalled (immediate or delayed recalls). Results suggested that AD patients were able to utilize semantic information in their immediate recall, though this was dependent on individual story characteristics. AD patient's delayed recall was essentially absent. Thus, no conclusions could be drawn with respect to the level of importance factor. NP patient's recall performance was similar to patterns observed in other clinical samples for both immediate and delayed memory.
