Sperry (1968)

Split Brain

PP's:
11 pp's who had undergone radical surgery to sever the corpus callosum.
First, a man who had been suffering from seizures for 10 years but after the operation, was seizure free.

Words or images can be flashed on screen, to one hemisphere, for 1/10th of a second which is too quick for the hemisphere to move and register the information.

PP's were then given objects and asked to then find the same object in a bag with either the same or opposite hand.

Visual material shown to the RVF can be described in speech and writing but if shown to the LVF, the PP's insisted they didn't see anything.
