Using a Chicken's Claw or Feet

An experiment done in 1978. discovered a unique phenomenon among split brain patients who were asked to perform a simultaneous concept task. The patient was shown two pictures, one of a house in wintertime and one of a chicken's claw or foot. So there is like some switching that goes on in the brain, everything is crisscrossed, whatever. A series of picture was placed in front of the patients and then they asked the patient to choose a picture with their right hand and apicture with their left hand.
