Movie Perception Test - Conversation

A movie perception test by Daniel Levin & Daniel Simons. Check out the book, The Invisible Gorilla, for more information (www.theinvisiblegorilla.com).

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).
