Benefits of training visuospatial working memory in young-old and old-old.

The purpose of the present study was to test the efficacy of a visuospatial working memory (WM) training in terms of its transfer effects and maintenance effects, in the young-old and old-old. Forty young-old and 40 old-old adults took part in the study. Twenty participants in each age group received training with a visuospatial WM task, whereas the others served as active controls and completed alternative activities. Training benefits were examined, considering (a) the specific training-related gains in a visuospatial WM task (criterion); and (b) the transfer effects on measures of verbal WM, visuospatial short-term memory, inhibition, processing speed, and reasoning. Maintenance of training benefits was also assessed after 8 months. Results showed that the trained groups (both young-old and old-old), but not the control groups, performed better in the WM measures and preserved these gains after 8 months. Some transfer effects were found, but only in the young-old-trained participants, and they were not maintained at the follow-up. These results are discussed in terms of the efficacy of WM training for older adults when a visuospatial modality is used.

Working memory training in older adults: evidence of transfer and maintenance effects.

Few studies have examined working memory (WM) training-related gains and their transfer and maintenance effects in older adults. This present research investigates the efficacy of a verbal WM training program in adults aged 65-75 years, considering specific training gains on a verbal WM (criterion) task as well as transfer effects on measures of visuospatial WM, short-term memory, inhibition, processing speed, and fluid intelligence. Maintenance of training benefits was evaluated at 8-month follow-up. Trained older adults showed higher performance than did controls on the criterion task and maintained this benefit after 8 months. Substantial general transfer effects were found for the trained group, but not for the control one. Transfer maintenance gains were found at follow-up, but only for fluid intelligence and processing speed tasks. The results are discussed in terms of cognitive plasticity in older adults.
