Emphasis Preaching Journal

Daniel Simons, professor of psychology at Harvard, made a video of two teams of basketball players, one team in white shirts and the other in black, each player in constant motion as two basketballs were passed back and forth. Observers were asked to count the number of passes completed by the members of the white team. After about 45 seconds of passes, a woman in a gorilla suit walked into the middle of the group, stood in front of the camera, beat her chest vigorously, and then walked away. Fifty per cent of the observers did not even see the gorilla.
