Left Brain/Right Brain

  

In 1976, Julian Jaynes coined the term “bicameral mind” in his eponymous book The Origin of Consciousness in the Breakdown of the Bicameral Mind.  According to this model, the brain is divided into two rooms—“bi” meaning ‘two,’ and “camera” meaning ‘room.’  (We call our cameras “cameras” because the first camera was a large room, much reduced now to the thin room which is an iPhone connected to the doorless room which is the digital ether.) According to this early research, the left brain was in charge of language and the right of imagery. In his landmark, 2009 book, The Master and His Emissary: The Divided Brain and the Making of the Wester World, author Ian McGilchrist offers a much refined theory, informed by extensive research since 1976, to show that both sides of the brain coordinate in the creation of experience.  With that proviso, we can consider how the predominant aspects of our divided brains function in the learning process.

In general, someone who functions predominantly from the left brain, as illustrated above, tends to construct experience as

Linear—one thing following the other in order

             Analytical and Mental

             Product oriented
             Closed
             Staid

Digital—favoring polar binary opposites, as, for example right or wrong, good or bad.

Numerical—clear, quantifiable order, favoring monetary and business systems

Conventional—according to tradition and popularly accepted values

Rule-bound and Prescriptive

Proscriptive—experience and action outside the parameter of accepted rules prohibited

Limiting—at best, the left brain can work four things in consciousness at a time

Rigid and strict

Dividing and Selective

External

Exclusive

“No”

Denotative—words mean discretely, without nuance

Ego and Superego—a will to power

Conscious

Prose

Boxed in

Guarantees
Fear based and inspired

We cannot live socially or in civilized cultures without these functions.  Some of the benefits of the Left Brain include a sense of security and constancy; organization and focus; and social and familial foundations.  The Left Brain identifies goals and marshals them to completion. Language, itself, functions because of Left Brain tendencies.

The problem comes when it presumes to take control of all the brains functions.  McGilchrist argues that, historically, the Left Brain was the emissary from the larger, the contrasting functions of the Right Brain, whose qualities include these:

Global

Contextual

Intuitive and epiphanic

Body and image based

Process oriented
      Open
      Fluid

Analog—favoring paradox and interweaving

Experimental and creative

Evolutionary and revolutionary

Descriptive

Expansive

Patient and flexible

Coordinating

Internal

Inclusive

“Yes”

Connotative

Id

Subconscious incubation

Dreams

Poetry

Out of the box

Possibility
Love based and inspired

The Right Brain is the repository of all of our history as a species—spatially and temporally.  It connects us in what sometimes feels magical ways. It offers us insight, joy, warning, possibility.

            Here’s an example of the difference between Left-Braining and Right-Braining.  I am an international folkdancer.  Every Wednesday night and on long vacations devoted to this art, we get together—women and men ranging in age from 20 to 100, and sometimes with children, to join hands and enjoy the dances from countries around the world and through time, to music that can be soft and prayerlike, or bawdy and rollicking.  After almost 40 years, I know most of the old dances and need only to hear the first few notes and my body knows the rest.  But there is always a leader, whom the rest of us watch.  If I were to put on the music at home, I would know neither the name of the dance nor which step comes next.  That’s because I have mostly Right-Brained these dances.  And, although I am known for being a “good dancer,” expressive, joyful, knowing how to style—and seem to know all the steps—I don’t.

            On the other hand, I have learned dances to teach others, and these I analyze into their component parts, memorize them, practice them, make and correct my mistakes while replaying videos.  I, in other words, take a Left-Brain approach, to “get it right,” correct others.  We have some master teachers in our folkdance group, who always know the steps, and whom the rest of us use as guides.  Too often, though, they devolve into a Left-Brainy make-wrong mode—conventionalizing, criticizing, scolding. What makes my teaching different from that of most other folkdance teachers, is that I also incorporate images in my teaching: “make believe you’re the Statue of Liberty, raising one hand and tucking in the other”; “make believe you are moving through water.”  This helps others to be expressive, joyful, stylized.  And I don’t scold.

            For me, when I’m at my best, this is an example of optimal coordination between the Left and Right brain.  Unfortunately, as Gilchrist argues so cogently in his book, the Left Brain functions have usurped control to assert the will to power. 

In politics, Left Brain leaders manipulate the voting public and constituencies with fear and rigid values. The traditional classroom, too, favors a Left Brain model. The posts on this blog serve as reminders that we are far larger and have greater capacities than the Left Brain would allow, by itself.  We invite the Right Brain into the mix, and favor

Imagery over plot

Experimentation over right/wrong

Community over leaders

Creativity over tests

Original over linear thinking

Learning over grades

Rainbow over black/white

Shapes over straight lines

Possibility over boredom

Spilling over the edges, like the picture above

Poetry over all

And more…

How are your learning experiences structured? Is there a generative balance of Left Brain/Right Brain in your classroom and in your learning process?
