Exploring the Specificity, Synergy, and Durability of Auditory and Visual Computer Gameplay Transfer Effects in Healthy Older Adults.

Abstract

To determine whether auditory and visual computer games yield transfer effects that (a) are modality-specific to verbal memory (auditory stimulus presentation) and visual-processing tests, (b) affect working memory and processing speed, (c) are synergistic for combined game-type play, and (d) are durable. A Pilot Study (N = 44) assessed visual transfer effects in a two-group pre-post design. The Main Study (N = 151) employed a 2 (visual games: yes, no) × 2 (auditory games: yes, no) × 3 (test session: pretest, post-test, follow-up) design, allowing different training groups to act as active controls for each other. Neuropsychological test scores were aggregated into verbal-memory (auditory presentation), visual-processing, working-memory, and processing-speed indexes. Visual-processing and working-memory pre-post-training change scores were differentially modulated across the four gameplay groups in the main sample, demonstrating transfer effects differing across both active- and passive-control groups. Visual training yielded modality-specific transfer effects in both samples, transfer to working memory in the main sample, and transfer to processing speed in the pilot sample. There were no comparable transfer effects for auditory training. Combined-visual-and-auditory training failed to yield synergistic effects or any significant transfer effects. Visual-processing transfer effects remained significant at follow-up. Visual and auditory games differentially modulated transfer effects. Domain-specific visual transfer effects were found at post-test and were durable at follow-up. Visual gameplay holds potential to ameliorate age-related cognitive decline in visual cognition.
