At what age does working memory peak?
Working memory capacity peaks in the mid-20s (around age 25) and then gradually declines. Digit span remains relatively stable through the 40s, but processing speed and dual-task performance begin to decline earlier. By age 70, average digit spans are typically 1–2 items shorter than in young adults.
