Assume that you are testing a split-brain human subject whose language center is in his left hemisphere. If you place a house key into his left hand, he will:
◦ not be able to tell you what object he is presently holding.
◦ immediately be able to tell you what he is holding.
◦ None of the above are correct.
◦ be able to tell you what he is presently holding if allowed to think about it for several seconds.
◦ not be able to later select the object he was holding from a group of various objects.
