Noteworthy psychological experiments of the 20th

In the early s, Nobel Prize-winning neuroscientist, Roger Sperry discovered that each hemisphere of the brain, the right and the left, has its own stream of consciousness, independent of the other.

Further, Sperry and other researchers have demonstrated that each hemisphere can carry out a different complex task—independent of the other—simultaneously—as if they are two people! No one experiencing inner conflict need ever again feel they are strange—that how their mind works is some anomaly of nature—or feel flawed.

Inner conflict is based in the very architecture of the brain, not in some aberration of mind.

This new look at inner conflict opens the door to an also new and profoundly beneficial self-understanding for millions of people suffering with it… who have believed, in their inner confusion, that they were somehow defective.

These are folks who have had the corpus callosum in their brain surgically severed in an attempt to reduce or eliminate epileptic seizures. The corpus callosum is a thick band of more than million neural fibers located between the left and right Noteworthy psychological experiments of the 20th of the brain.

These information-carrying fibers fan out from this central bundle between the hemispheres, reaching deep into the furthest reaches of both hemispheres. It is the conduit for information shared by the hemispheres with each other. Sperry and his colleagues observed that after disconnection of the corpus callosum, these patients appeared normal and seemed to interact with others normally, but with cleverly designed experiments he found another story.

He formulated a way to present visual and kinesthetic touch information—words, pictures, and objects—to only one hemisphere at a time, and then to observe the resulting behaviors in these patients. By the fact each hemisphere is isolated from the other, he was able to test and compare the individual capabilities and skills of each hemisphere in many different types of cognitive tasks.

Also important to note is what Sperry did NOT say. An advanced targeted search on the web site of bookseller, Amazon.

A similar search on Google will turn up over 2, hits. Even with many duplicate hits, that has to mean half a million web sites with articles or books on the subject of right and left brain.

Many authors, though meaning well and accomplishing some good for their readers, make claims for the capabilities of the right or left hemisphere that go far beyond the conservative and scientific boundaries Roger Sperry stayed within.

They have turned good science into not so good pop science. It was a once-in-a-career insight. Stay with me and consider.

In the lab, during the testing itself, they observed occasional conflicts between the hemispheres during certain tests. And during some experiments, where the right hemisphere has been shown to have better than normal linguistic capabilities in certain split brain patients, they found significant differences in opinions, preferences, and personal styles of communication between the hemispheres.

Before I go into examples of these conflicts and test results, I need to add some supporting information so they will all make more sense. Studies of stroke victims demonstrate it conclusively.

But there is more to that story. Broken down between left and right-handers, the stats go something like this. Of every people, are right-handed, 20 are left-handed. Advanced linguistic skills and in some cases speech capability in both hemispheres thus did show up in a few split brain patients, and a few developed it post-surgery.

These few are the favorites for testing by investigators because they offer more interesting testing possibilities. But even without the ability to talk, tests prove right hemisphere personalities have language capabilities. They understand words and pictures, and relationships between them.

When shown a word, they can pick out the picture from an array that correctly corresponds with the word. From a picture, they can pick out the correct word for it from a set of choices.

When they palpate, or feel an unseen object, they can pick out from a set of choices the correct word for that object, and they can follow verbal instructions.

When integrated via the corpus callosum, both categories of information—nonverbal and verbal—are each essential components of emotional intelligence.The s were a period of continued experimentation.

Time is what we use a clock to measure. Information about time tells us the durations of events, and when they occur, and which events happen before which others, so time has a very significant role in the universe's organization.
