We’re a bit embarÂrassed to admit that it took us three times to spot the change in this fasÂciÂnatÂing video illuÂsion at New SciÂenÂtist, even after readÂing about the research behind the video. The test was develÂoped by Kevin O’ReÂgan and his team at the UniÂverÂsiÂty of Paris Descartes as part of their work on perÂcepÂtion. O’ReÂgan is best known for his work on change blindÂness, our relÂaÂtive inabilÂiÂty to perÂceive gradÂual change, and our tenÂdenÂcy to focus soleÂly on what we perÂceive to be the most dynamÂic or interÂestÂing eleÂment of a scene.
If this video isn’t enough to conÂvince of you of O’ReÂgan’s theÂoÂries, he’s postÂed a whole slew of demonÂstraÂtions at his webÂsite. BetÂter yet, you can disÂpel any remainÂing doubts (or self-esteem) by takÂing this awareÂness test, which is even more draÂmatÂic. It bowled us over. Let us know in the comÂments if it did the same for you.
