A researcher replicates key conditions of Sperry's (1968) split-brain study with a patient who has undergone a complete commissurotomy.
Describe the patient's expected response or behavior in each of the following three test scenarios:
A picture of a spoon is flashed to the patient's left visual field (LVF), and they are asked to state verbally what they saw.
A picture of a key is flashed to the patient's left visual field (LVF), and they are asked to use their left hand to select the matching object from a bag of concealed items.
The word 'TEA' is flashed to the patient's left visual field (LVF) and the word 'CUP' is flashed to their right visual field (RVF) simultaneously. The patient is asked to write down what they saw using their right hand.
