Document Summary
Psyc 1010 lecture 2 notes hemispheric specialization in the intact brain and the endocrine system: another way to communicate and heredity. The problem with the split-brain operation, of course, is that it creates a highly abnormal situation. Moreover, the surgery is done only with people who suffer from prolonged, severe cases of epilepsy. These people may have had somewhat atypical brain organization even before the operation. Moreover, the number of split-brain patients has been quite small. Only ten split-brain patients have been studied intensively. Thus, theorists couldn"t help wondering whether it was safe to generalize broadly from the split-brain studies. For this reason, researchers developed methods that allowed them to study cerebral specialization in the intact brain. One method involves looking at left-right imbalances in visual or auditory processing, called perceptual asymmetries. As we have seen, it is possible to present visual stimuli to just one visual field at a time.
