Recent findings underline the importance of REM-sleep for procedural memory consolidation in
young adults. In light of age-related declines in memory processing as well as REM-sleep this
relationship was investigated in healthy older adults (60-85y/o; n=47). An augmentation of
REM-sleep was achieved physiologically through REM-rebound and pharmacologically by a
placebo-controlled AChE-Inhibitor while performance in a procedural and declarative learning
task was investigated before and after sleep. REM-sleep percentage proved to be significantly
associated with performance-time in the morning procedural learning task after statistically
controlling for evening performance (test1: r=-.310[p=.019]; test2: r=-.274[p=.035]; test3:
r=-.441[p=.001]; test4: n.s.; test5: r=-.349*[p=.022]; test6: r=-.247; p=.055)).

The purpose of this study was to examine the relationship between memory self-efficacy (MSE)
and a 6-year follow-up assessment of memory functioning in a sample of older Dutch persons.
MSE was assessed by a Dutch abridged version of the Metamemory in Adulthood questionnaire
(MIA). The total MSE score predicted memory performance at six years. A separate analysis of
the different MSE subscales indicated that the MIA Change score was the most salient feature of
MSE. An extreme groups analysis of the MIA Change score revealed that those who perceived
that their memory was deteriorating, scored worse across a memory task.

Middle-aged and older people often worry that their diminishing memory may indicate incipient
dementia. This study evaluates whether subjective memory complaints predict lower performance
on memory and information processing speed tasks in a large cross-sectional and longitudinal
study involving 401 subjects aged 55 to 85. Results at baseline show that subjects with memory
complaints appear to perform worse in delayed recall compared to subjects without memory
complaints. At 6-years follow-up, there was no significant difference in cognitive performance
between these two groups, indicating that memory complaints are no predictor of cognitive
impairment on the long term.

Inhibitory effects in collaborative recall have been attributed to cross-cuing among partners, in the
same way that part-set cues are known to impair recall in individuals. Cues had an inhibitory
effect on recollection in the early part of the recall period. There was no difference between the
