Individuals with poor working memory tend to have trouble planning, organizing, and carrying out daily chores such as running errands, because it requires mentally formulating a “to do” list organized by time and location. Study skills may also suffer. Working memory allows us to keep track of priorities and helps us block the external or internal distractors that can derail us from the task at hand. Working memory helps us persist with tasks that require focused attention over time. Any of us, even those with strong working memories, can experience working memory problems when overly tired, anxious, or stressed.
