This time the acronym SAT stands for Selective Attention Test. In the late 1990s, Daniel Simons and his student Christopher Chabris created a 60 second test for how the brain processes visual information. It was outrageously simple: it required only that you watch people passing basketballs. Their experiment would become one of the most famous brain quizzes of the past half-century. Media outlets around the world publicized the test, and NBC aired a Dateline feature about it.
Watch the video below to test your brain.
How did you do? Did you get the count right? I counted 17. Did you catch the surprise? I did!
Simons (this time without Chabris) recently updated the famous gorilla experiment. Watch the video below for the updated experiment.
Did you catch the gorilla this time? Did you catch the other suprises? I saw the gorilla and guessed the correct number but I missed the student leaving. Share your results.
Here's a recap of the update: The new video also features students divided into two teams, passing basketballs. We are instructed again to count the number of passes by players in white. The gorilla is back. But there are two new visual tricks: a curtain behind the players changes color during the video, and one of the players in black walks out of the frame.
