Your memory is no video camera: It edits the past with present experiences

Your memory is a wily time traveler, plucking fragments of the present and inserting them into the past, reports a new study. In terms of accuracy, it’s no video camera. Rather, memory rewrites the past with current information, updating your recollections with new experiences to aid survival. Love at first sight, for example, is more likely a trick of your memory than a Hollywood-worthy moment.

Your memory is a wily time traveler, plucking fragments of the present and inserting them into the past, reports a new Northwestern Medicine study. In terms of accuracy, it’s no video camera.Rather, the memory rewrites the past with current information, updating your recollections with new experiences.Love at first sight, for example, is more likely a trick of your memory than a Hollywood-worthy moment.”When you think back to when you met your current partner, you may recall this feeling of love and euphoria,” said lead author Donna Jo Bridge, a postdoctoral fellow in medical social sciences at Northwestern University Feinberg School of Medicine. “But you may be projecting your current feelings back to the original encounter with this person.”The study will be published Feb. 5 in the Journal of Neuroscience.This the first study to show specifically how memory is faulty, and how it can insert things from the present into memories of the past when those memories are retrieved. The study shows the exact point in time when that incorrectly recalled information gets implanted into an existing memory.To help us survive, Bridge said, our memories adapt to an ever-changing environment and help us deal with what’s important now.”Our memory is not like a video camera,” Bridge said. “Your memory reframes and edits events to create a story to fit your current world. It’s built to be current.”All that editing happens in the hippocampus, the new study found. The hippocampus, in this function, is the memory’s equivalent of a film editor and special effects team.For the experiment, 17 men and women studied 168 object locations on a computer screen with varied backgrounds such as an underwater ocean scene or an aerial view of Midwest farmland. Next, researchers asked participants to try to place the object in the original location but on a new background screen. Participants would always place the objects in an incorrect location.For the final part of the study, participants were shown the object in three locations on the original screen and asked to choose the correct location. …
