Our ability to keep track of ongoing thoughts, plans, actions, current tasks, and changes around us is essential for everyday living. This ability is known as working memory, a system of the brain that allows us to focus on what we are doing, switch tasks, solve problems, or do several things at once such as walking and talking. However, scientists disagree about what limits our working memory ability, and how those limits change as people grow older.The project Working Memory Across the Adult Lifespan (WoMAAC) brings together three research groups who disagree with different theories of how and why working memory changes with age.  Here to discuss are psychology researchers Professor Robert Logie and Dr Alicia Forsberg, both part of the University of Edinburgh project team.  Related links: WoMAAC project website
