Massed versus spaced visuospatial memory in cognitively healthy young and older adults
BACKGROUND: The present study examined the effect of massed versus spaced learning
trials on 24-hour delayed recall for a visuospatial learning task. To determine the utility of
measuring the incremental benefit of spaced training as a cognitive assay that may be useful
in early clinical trials, we used a within-subject crossover design, with two small samples
(typical sample sizes for phase I clinical trials). METHODS: Young adults and cognitively
healthy older adults without significant physical, neurological, or psychiatric illness were …
