Working Memory Across the Adult Lifespan: An Adversarial Collaboration, 2016-2020

The research involves 17 experiments to examine how healthy adult volunteers aged 18-75 perform when they are asked to remember words or visual patterns at the limits of their working memory capacity, and are asked to make simple rapid decisions (such as whether a string of letters is a word or not, or taps into their general knowledge of the world). The experiments will look at how people cope with focusing on the memory task or on the decision task, or are asked to do both at the same time. Two of the experiments will involve large numbers of people performing a range of tests to see if, e.g. people who are good at memory tests are also quick and accurate on decisions, or good at memory and making decisions at the same time. Each theory makes different predictions for the results of our planned experiments. The planned research has significant potential for new theoretical developments, and for major advances in the understanding of this key human ability across the adult lifespan. Crucially, it will reveal whether all of working memory declines with age or whether some aspects remain largely intact, with important implications for design of technology for older users, and for lifelong education and training.
