I was reading in Time’s cover story in June about how Tom Cruise is
ambidextrous, and is learning how to use two weapons at once for the
upcoming film "The Last Samurai".
How do people get to be ambidextrous?
I heard a theory about how left-handed people, as a generalisation,
are smarter than right-handed people. Apparently this is because the
civilised world is made for the right-handed (ever see the Simpsons
episode where Ned Flanders opens a leftorium?), so the left-handed end
up developing their right hands and therefore have a more fully
developed brain. Or something.
Is there anything to this theory?
Are ambidextrous people smarter than non-ambidextrous people?
Are there any exercises that I could do to develop ambidexterity?
HI Markabe!
Two questions -- if you've a mind to answer them. First, are you
left-handed? Second, does your question require an answer which helps
you meet an academic goal?

Hello:
I found this question interesting not for the money, but because I'm
ambidexter (or ambidextrous) so I thought it was a nice opportunity to
know more about that. In my case I'm left-handed but my mother forced
me when I was a child to write with the right hand. So I write with
the right hand, I throw things with my left hand and I usually play
football with both legs ;-). I was the first of my class, but I think
this hasn't anything to do with that capability, because my sister was
also the first and she is right handed, I think this is caused by a
combination of genetics and the surrounding environment, but if you
pay some attention, a lot of important people are left handed.

This doesn't mean they are smarter than the rest, but it's curious ;-)
Let's look the definition of ambidexter:
Ambidexter (Dictionary.com)
http://dictionary.reference.com/search?q=ambidexter
"Am`bi*dex"ter, n. 1. A person who uses both hands with equal
facility."
Cambridge International Dictionary of English
ambidextrous - adjective: able to use both hands equally well
And searching over the web I have found very interesting results:
Article "'Ambidextrous People' are Brain-Damaged" taken from the
M nchener Medizinische Wochenschrift
http://www.linkshaender-beratung.de/english/Ambidextrous.htm
This is an interesting "hypotesis" about ambidextrous:
"When the brain is deprived of oxygen, the dominant cerebral
hemisphere is the most significantly damaged for the very reason that
it must fulfill more of the brain's functions and has consequently a
greater oxygen requirement. Through oxygen deprivation, disturbances
in the naturally dominant cerebral hemisphere are manifest. This means
that a child who suffered such damages switches back and forth between
using the left and right hand and may at first even perform worse with
the dominant hand than with the non-dominant hand while, for example,
drawing or writing. The outside influence of the socio-cultural
environment, namely the "right-handed culture", may have life-long,
detrimental effects on left-handed children, the overwhelming majority
of whom are exposed to environmental attitudes like "Left-handedness
is an aberration" or "We live in a world that is set-up for
right-handers". The process of converting the child can then have
massive detrimental effects that can extend across the child's entire
life. Thus, frequently, the natural development is interrupted.
Namely, the process of cerebral compensation, favoring the hand that
is not dominant, is negatively affected. This is especially evident in
writing. In this way, these children then suffer new damage. The
healing processes initiated (namely, compensation by other regions of
the brain) are then disrupted once again and the slowly convalescing
dominant cerebral hemisphere is damaged anew."
AMBIDEXTERITY EXERCISE
http://www.mind-course.com/ambi.html
A courious page about ambidexerity, it answers the question about how
people get ambidexter, the answers is by training ;-)
"Ambidexterity is the ability to use both your hands with equal ease
or facility, but if you're armless, it could be your feet! In fact, it
is quite advantageous in certain sports and martial arts to be able to
use both your feet with equal facility. The Greeks encouraged and
tried to promote ambidexterity because it was simply logical in sports
and battle to be adept with both hands instead of one. By combining
the Phoenician style of writing right to left with their own left to
right system, the Greeks created a reading and writing system called
boustrophedon, where the lines ran alternately right-to-left and
left-to-right. With alternating sweeps of the eyes back and forth,
reading was more swift and efficient."
Video Games Develop Ambidextrous Brains
http://www.bear-left.com/original/2001/0401vdeo.html
"The New England Journal of Medicine will report tomorrow that
scientists have discovered that children who play video games a
minimum of 20 minutes three times a day develop ambidextrous brains.
Most of us know that video games are one of the most popular forms of
entertainment, especially for children and adolescents. Few of us knew
the developmental benefits children received from such activity."
Games Do Make You Smarter
http://puzzles.ngenres.com/news/108.html
"For every negative study there are positive studies, highlighting the
potential benefits of video games. A report by the New England Journal
of Medicine in 2001 suggests that video games can help to develop
ambidextrous brains in young children, who are otherwise drawn to
activities controlled by their brain side preference. In this study,
children who played video games a minimum of 20 minutes three times a
day exhibited left and right brain co- operation, implying that they
could be both logical and intuitive rather than one or the other."
Left Handed Frequently asked questions
http://www.anythingleft-handed.co.uk/faq.html
"What is "Cross Laterality"?
This is a mixture of sidedness, such as left-handed but right-footed
and right-eye, and can cause some co-ordination problems. Crossed
hand/eye dominance can affect performance in some sports, particularly
racquet sports where the field of vision might sometimes be
restricted.
It can be advantageous in gymnastics, running and netball, because
positioning of the body would be more evenly distributed for better
balance. Young children may appear cross-lateral before they settle on
a particular hand preference. It is important to note that
cross-laterality, left-handedness and undetermined handedness are not
causes of learning difficulties or disabilities, as we are sometimes
led to believe. However they may appear in addition to them. (e.g.
dyslexia, dyscalculia, ADD/ADHD) If a child is having learning
difficulties, it is unlikely to be because they are left-handed or
cross-lateral, so always look further for an underlying cause."
Conclusion
You can find two types of ambidexter people:
-Left-handed forced to use the right hand (like me), and this makes
that person grow with the capability to use both hands in the same
way.
-People with cross-laterality, people which use different parts of the
body for different tasks, such as left-handed but right-footed.

revbrenda1st,
To answer your questions:
1. No, I'm right-handed.
2. It's not so much academic. I do remember having read an article in
the Weekend Australian magaine supplement about increasing your
intelligence, and one of their suggestions was to use your
less-dominant hand more to do physical tasks, thus exercising the
corresponding half of the brain.
I just think being ambidextrous would be very useful.
