Around eight months of age, children develop the cognitive capability called object permanence. Developmental psychologist Jean Piaget coined the term object permanence, that refers to the cognitive understanding that even when a secure object is out of sight, it doesn’t cease to exist. Even if we can’t see, hear, or touch someone or something, we can access the memory of its existence in our mind. Imagine how much psychological comfort this cognitive capacity we all develop brings, given healthy and normal development. Have you ever felt lonely and imagined calling someone you love and what they might say to comfort you? Have you ever run a race and imagined the people who support you waiting with smiling faces at the finish line—especially when you feel like stopping? Has it ever brought comfort and solace to remember the funny and loving memories of a relative who has died? Object permanence can be protective and inspire courage in moments when we feel alone, distressed, or stressed.
