- The effectiveness of two memory training programs designed to enhance four-digit number recall was examined in 90 healthy older adults. One group received instruction and training in the number-consonant mnemonic, whereas another group was instructed to adopt their own encoding and retrieval strategies to enhance number recall. Also, a control group receiving no training between testing occasions was included. The criterion task was administered according to the Buschke selective reminding procedure. Posttest performance was evaluated with and without cognitive support for remembering (i.e., verbal cues). Under unsupported conditions, the mnemonic group improved number recall following training and the selfgenerated strategy group showed a tendency in the same direction. When support was provided, group differences in favor of the two training groups increased. In addition, no training-related gains were observed in two verbal transfer tasks. The relatively similar patterns of gains in the two intervention groups were discussed in terms of advantages and disadvantages in the two training regimens balancing each other.

- We examined cross-sectional differences and longitudinal changes in episodic memory performance related to impending death among a group of very old people, aged 90–101 years. Participants were assessed at 3 measurement points across a 6-year interval. Three groups were identified: those who survived the entire follow-up period (n =40), those who died before the first follow-up (n =44), and those who died after the first follow-up (n =14). Participants completed a battery of episodic memory tasks consisting of face recognition, word recognition, word recall, and object recall with selective reminding. Those who survived performed better than those who were going to die in object recall at baseline. A Cox regression analysis, controlling age, revealed that object recall performance was significantly related to subsequent mortality status. Longitudinal analyses demonstrated significant 3-year decline for both face recognition and object recall, but no evidence of differential decline as a function of mortality group. Thus, longitudinal changes in memory preceding death were not as pronounced as the corresponding cross-sectional differences in this very old sample. In general, the results suggest that mortality-related memory deficits are present in extreme old age, although these deficits are relatively small and task-specific.

- This article describes the Betula Study with respect to objectives, design, participants, and assessment instruments for health and cognition. Three waves of data collection have been completed in 5-year intervals since 1988-1990. A fourth wave started in 2003 and will be completed in 2005. An overview of Betula research is presented under the headings of memory and cognition and cognitive neuroscience. Health-related issues and sex differences as well as comparisons between cross-sectional and longitudinal studies are discussed in the first section. The influence of different genes and of some brain abnormalities for memory functioning in adulthood and old age constitute main topics in the second section. New data are presented on the association between blood pressure and dementia. We demonstrated that a demented group of participants had higher levels of systolic blood pressure and pulse pressure than non-dementia controls 10 years before diagnosis. The new fourth wave of data collection will, in addition to enriching the Betula database, permit revisiting and reanalyzing the existing data from new perspectives.
