Simons and Chabris (1999) conducted a study on inattentional blindness where participants were asked to count the number of passes made by a subset of a group of basketball players. This task was designed to focus the participants' attention so narrowly that they would fail to notice an unexpected event, such as a person in a gorilla suit walking through the scene.
