OBJECTIVE: The aims of this study were to assess whether computerized attentional training improves dual-tasking abilities in older adults and whether its effect and transfer are modulated by age and the type of training provided. This study also used virtual reality (VR) as a proxy to measure transfer in a real life related context. METHOD:Sixty participants (30 older and 30 younger adults) were randomized to either: (a) single-task training (two tasks practiced in focused attention; visual detection and alphanumeric equation task); or (b) divided attention variable-priority training (varying the amount of attention to put on each task when performed concurrently). Training effects were assessed at pre- and post-training with tasks similar to the one used in training. Transfer was measured with the virtual car ride, an immersive dual-task scenario and a self-reported questionnaire. RESULTS: In older adults, variable-priority improved attentional control abilities and led to better transfer in the VR dual-task scenario compared with single-task. Younger adults benefited equally from the two types of training and transfer was found on the Alpha span task when performed concurrently in VR. Single-task improved the ability of all participants to carry out the tasks in the focused attention condition. No transfer effects were found on the self-reported measure for either training type or age. CONCLUSION: Attention remains plastic in old age and programs designed to improve attentional control might be beneficial to older adults. Importantly, training can produce transfer to more real life related tasks and transfer remains possible throughout the life span. (PsycINFO Database Record (c) 2018 APA, all rights reserved).
