This video shows footage from a 1998 study by Daniel Simons and Daniel Levin in which a participant fails to notice when the person he is talking to is replaced by someone else. The study was among the first to demonstrate that the phenomenon of "change blindness" can occur outside the laboratory. This was the first of many studies by Dan Levin and I and our colleagues conducted to explore how change blindness can occur in the real world.

A movie perception test by Daniel Levin & Daniel Simons. The video itself was used in research by Levin and Simons that was published in 1997 in Psychonomic Bulletin & Review. The video is copyrighted and is provided here for individual viewing purposes only. If you would like to use it in teaching, talks, or presentations, it is available on DVDs from Viscog Productions (www.viscog.com).
SPOILERS AFTER THIS POINT:
The video is a well-known demonstration of the phenomenon of change blindness: people fail to notice large changes to scenes when those changes occur during a brief disruption like a film cut. In the original study, people who were not expecting changes noticed none of the changes in this movie. On a second viewing, when they were looking for changes, they noticed fewer than 2 of the 9 changes on average. The changes are obvious once you know to look for them, but they do not grab attention automatically. You can learn more from the original journal article that is available from my reprint archive (http://www.psych.uiuc.edu/reprints/simons) or from my book with Christopher Chabris, The Invisible Gorilla (www.theinvisiblegorilla.com).
