Roger sperry and w. j. in the 1960"s. Used tachistoscope: a projector that had a shutter and therefore could project images/words for 1/10th of a second. Split-brain patients asked to press key underneath their table if they saw an image and then were asked by experimenter if they saw it. Objects flashed on the left side entered the right side of the brain and vice versa. One part of the brain is better at language. Left side- language, seeing patterns and producing principle from it.
