  • Understanding Individual Differences in Working Memory Training and Transfer in Older Adults

    open to eligible people ages 50-85

    The present study investigates how individual differences in cognitive processing contribute to the efficacy of working memory training programs in an older adult population. In a randomized crossover design, different types of working memory training interventions will be evaluated within the same participants. Adding game-like elements to working memory training programs can increase motivation and engagement, which can increase learning. However this process, termed gamification, adds sensory complexity that can lead to increased mental load and/or distraction in older adults. Investigators hypothesize that gamification of training tasks will be beneficial to some and counterproductive to other participants. The investigators will test two models; the first assumes that participants with difficulty inhibiting distracting information will show better learning and transfer when assigned to non-gamified training, whereas those with more distractor tolerance will show better learning and transfer when assigned to gamified training. The second model states that the outcomes of the intervention will be better predicted by performance on measures of general cognitive ability. In a separate study, the investigators will compare working memory training that contains rich, multisensory information with a training program that contains only visual information. Here they will also test two models; the first assumes that participants with difficulty binding two stimulus streams will show better learning and transfer when assigned to visual-only working memory training, whereas participants who do not have this difficulty will show better learning and transfer when assigned to multisensory working memory training. The second model states that the outcomes of the intervention will be better predicted by performance on measures of general cognitive ability.
