The Lifespan Cognition Lab seeks to understand age-related changes in cognitive functions, such as memory and attention. Current research examines working memory, a process that allows for simultaneous storage and processing of information that is used for many everyday behaviors, such as reading and driving. To test working memory, we use n-back and the repetition detection task (Bopp, 1999) which requires a participant to find a repeated digit or location in a grid. The tasks are challenging, but fun. All research is discussed with participants at the conclusion of each study. To participate, please contact Dr. Bopp at
