A science experiment on the brain? Yes! This experiment gets inside your head
and makes some revealing determinations! You've heard of being right or left
handed but how about left or right brained? Are you left brained or right
brained? Left brain people tend to be
logical Authentic
Alshon Jeffery Jersey , sequential, rational and analytical. They are
usually objective and tend to look at small parts. Right brain people on the
other hand are more random and intuitive. They are holistic, synthesizing,
subjective, and tend to look at the whole instead of the parts.

This
left-brained Authentic
Robbie Gould Jersey , right-brained or hemispheric theory of the mind
suggests that the two different sides of the brain control two different "modes"
of thinking. It also suggests that each of us prefers one mode over the other.
If this theory holds true it may explain why people look at and do things in
different ways.

Many of us have a preference for one of these styles of
thinking. While others are more "whole-brained" being equally adept at both
modes. Most schools favor left-brain modes of thinking, while downplaying the
right-brain ones. Left-brainers focus on logical thinking, analysis, and
accuracy. Right-brained subjects focus on aesthetics and feeling.

Which
one are you? Left or right? Are you better at art, video
games Authentic
Jared Allen Jersey , or sports? Are you a good dancer? The things we like
to do and what we are good at are often because of how our brain works.
Ultimately, this has an effect on how the body and brain work together. For
example, some people are well coordinated while other people tend to be
clumsy.

This left-brain, right-brain theory provides a wonderful
opportunity to conduct a great science experiment! Try this experiment on
yourself, family and friends. You'll find out more about why you and others do
what the things they do.

The experiment is a two step process and is easy
to conduct; it's basic observation and noting experiment results. Your subjects
will answer a few questions and perform a few simple movements which you will
carefully observe. For part
one Jim
McMahon Jersey , ask them these questions and write down their
answers:

1. When you enter a theater which side do you prefer; A. left or
B. right?
2. What style of test question do you like; A. truefalse or B.
discussion?
3. Do you have hunches; A. no or B. yes?
4. Are you A. neat or
B. sloppy?
5. When learning to dance is it easier to A. follow the teacher,
or B. feel the music?
6. Can you tell time without a watch; A. no or B.
yes?
7. Which is easier for you; A. specific details or B. main
ideas?

If your subjects answered most questions with the "A" answer, they
are likely left-brained. If most of your answers were "B", they are probably
right-brained. But the experiment is not yet complete.

For the part two
of the science experiment you'll ask your subjects to do these simple movements
to determine hand dominance, foot
dominance Dan
Hampton Jersey , eye dominance, and ear dominance. This is where the
experiment gets interesting since right hand actions are actually controlled by
the left side of the brain and left hand actions are controlled by the right
side of the brain. We'll go into this in more detail when we tally the results.
For now ask your subjects to perform these actions:

Hand Dominance -- Ask
your subjects to write their name, cut a piece of paper in half, throw a ball,
eat with a fork and
finally Walter
Payton Jersey , take a drink of water. Note which hand they used for each
action.

Foot Dominance -- Ask your subjects to kick a ball, step up
three steps, and finally, step onto a coin on the floor. Note which foot they
use for each action.

Eye Dominance -- Ask your subjects to look through a
tube at a distant object. Ask them to look through a hole cut out of a piece of
paper. Note the eye used for each action.

Ear Dominance - Tell your
subject you want to whisper something in their ear; note which ear they offer
you.

Time to tally the hand dominance, foot
dominance Mike
Ditka Jersey , eye dominance, and ear dominance results. Remember that
actions are controlled by the opposite side of the brain. In other words, left
side actions are controlled by the right side of the brain and right side
actions are controlled by the left side of the brain. So if your subject used
their right ear to listen, you would write down the left side of the brain for
that action. If your subject used their left hand to write, you would write down
the right side of the brain for that action.

Compare the answers from
part one with the results from part two. How many left-brainers were there? How
many right-brainers? Do you have any who fit in both categories? If
so Dick
Butkus Jersey , these are whole-brainers.

Some people believe that
the hemispheric brain theory is non-sense. They believe that most people use
both sides of the brain at all times rather than using just one side of the
brain at a time. They believe that to solve complicated problems such as a math
problem you use both sides of the brain -- the logical and the creative side.
So, if we use both brains all the time - at the same time - how could we prefer
one side over the other as the hemispheric brain theory suggests?

What do
you believe? Are your right-brained subjects more creative type people? Are your
left-brained subjects more analytical type people? Perhaps the answer to the
theory lies in the results of your science experiment.
