Limited Benefits of Heterogeneous Dual-Task Training on Transfer Effects in Older Adults.

چکیده
Objectives It has often been reported that cognitive training has limited transfer effects. The present study addresses training context variability as a factor that could increase transfer effects, as well as the manifestation through time of transfer effects. Method Fifty-eight older adults were assigned to an active placebo or two dual-task training conditions, one in which the training context varies between sessions (heterogeneous training) and the other in a fixed training context (homogeneous training). Transfer was assessed with near and far-modality transfer tasks. Results Results show that heterogeneous and homogeneous training led to larger near-modality transfer effects than an active placebo (computer lessons). Transfer effects were roughly comparable in both training groups, but heterogeneous training led to a steeper improvement of the dual-task coordination learning curve within training sessions. Also, results indicated that dual-task cost did not improve in the active placebo group from the pre- to the post-training sessions. Discussion Heterogeneous training showed modest advantages over homogeneous training. Results also suggest that transfer effects on dual-task cost induced by training take place early on in the post-training session. These findings provide valuable insights on benefits arising from variability in the training protocol for maximizing transfer effects.

Objectives: The inability to allocate attention to balance when performing concurrent tasks may cause the older adults to fall. Therefore, thisstudy aimed to investigate the effect of 2 types of dual-task training on the balance of older adults. Methods & Materials: This quasi-experimental study included 36 eligible older adults (aged>65 years) living in Kerman City, Iran. The s...

Purpose: The purpose of this study was to compare the effects of two different approaches of dual-task training and executive training on lower limb muscular activity in older adults with balance impairment. Methods: This was a quasi-experimental study performed with the pre-test and post-test method. Thirty older adults (age= 73.8±4.6, height= 1.65±0.06, weight= 69.17±12.67) were randomly ass...
متن کاملAn Investigation of Response and Stimulus Modality Transfer Effects after Dual-Task Training in Younger and Older
It has been shown that dual-task training leads to significant improvement in dual-task performance in younger and older adults. However, the extent to which training benefits to untrained tasks requires further investigation. The present study assessed (a) whether dual-task training leads to cross-modality transfer in untrained tasks using new stimuli and/or motor responses modalities, (b) whe...

Cognitive training, physical activity, and exercise have often been reported to improve cognitive performance in older adults. This paper reviews some seminal and recent studies using these approaches to improve cognition and physical functioning in healthy older adults and in patients suffering from non-neurological chronic medical conditions. Results from cognitive training studies suggest th...
متن کاملBenefits of cognitive dual-task training on balance performance in healthy older adults.
BACKGROUND There is growing evidence of the involvement of executive control in the maintenance of balance in old age. We examined whether healthy older adults who completed five sessions of nonmotor cognitive dual-task training would show significant improvements on measures of dual-task standing balance and mobility, compared with an untrained control group. METHODS Twenty healthy older adu...
