? Patients were instructed to stare at a dot in the middle of a screen.
? The composite pictures were flashed briefly on the screen.
? Patients would report only the person shown in the right half of the picture.
? The left hemisphere, which could talk, only saw the right half of the picture, so nothing seemed unusual.
