Ambidextrousness And Memory: Can Dual Handedness Boost Your Brain?

| Podcast

Can you write legibly with both your left and right hands?

Midway through a gig, can you swing the guitar to your left arm and continue strumming the ballad?

If you can, you are part of that 1% of the population who do not have a dominant hand and experience ambidextrousness.

And as you’re about to discover, ambidextrousness truly is an experience!

If you are ambidextrous, you’re in good company too. Or at least, interesting company.

Other members of this ‘exclusive’ group include Benjamin Franklin,  Kobe Bryant, and even Nikola Tesla, just one of many reasons I featured him on the cover of The Memory Connection:

The idea that becoming ambidextrous boosts brain function has existed for over a century.

Moreover, it is also claimed that if you harness this ‘power’ you can improve your academic performance, decision making skills and grasp difficult concepts quickly.

Can ‘learning’ to become ambidextrous really have all these advantages?

Let’s find out:

Ambidextrousness: A Dual Handed Benefit?

 

There is a bit of confusion regarding the actual definition of ambidextrousness.

You are ambidextrous, if  you can perform any task equally with either hand, for instance, write legibly using either of your hands.

However, if you do some tasks with your right hand and others with your left, experts will term it as being mixed-handed.

Jimi Hendrix is a good example of mixed-handedness. He used his left hand to throw and comb his hair, but he wrote, ate and held the telephone with his right hand.

 

How To Become Ambidextrous?
(Because Few Are Born This Way)

 

In the 1800s Paul Broca and Carl Wernicke discovered that different hemispheres of the brain handled different functions such as speech, language and even motor functions.

But it was only in 2009 that scientists researched around 25,000 families and found certain genes were responsible for ambidextrousness in people.

Then in 2015, researchers found that brain function within the cerebellum is responsible for creativity.

This certainly proves why many ambidextrous people have unconventional problem solving abilities.

Creative Geniuses, Or:
The Celebrities Of Ambidextrousness

 

Nearly 60 years after his death, neurosurgeons studying Einstein’s brain discovered that his brain hemispheres were extremely well-connected. The ability to use the right hemispheres creativity and the left hemispheres logic gave the Father of Relativity a significant advantage from his peers.

Despite a lack of evidence proving Einstein’s ambidextrousness, the study confirmed Einstein’s non right-handedness.

Another historical figure who belonged to the ambidextrous club was Leonardo Da Vinci. The famous artist (and scientist of art) could easily write with both hands.

When Da Vinci wrote an ordinary letter, he used his right hand.

However, he wrote his secret diaries in mirror writing using his left hand which made it difficult for others to read.

Are All Ambidextrous Individuals Creative Geniuses?

 

Not really!

Left-handed tennis player Evgenia Kulikovskaya can switch her racket hand mid game to keep hitting forehands when her left hand gets tired. She doesn’t have a backhand!

The Controversial History Of Ambidextrous Training:
John Jackson

 

Though many modern studies link ambidextrousness with increased brain function in both hemispheres of the brain, this idea was not well received at first.

In 1905, English educational reformer, John Jackson established the Ambidextral Culture Society. He believed that a two handed, two brained society encouraged superior learning as it engaged the entire brain.

He also expected a lot from his disciples. Whether it was playing the piano with one hand or writing a letter with the other, he required his disciples to execute them flawlessly.

Was he successful in his mission?

Not quite.

His society was a laughing stock of the scientific community at the time.

Leading British neurologist, James Crichton-Browne criticized the society and even warned Jackson against going the evolutionary process.

John Jackson’s movement died out in the 1920s.

However, his ideas did not. They continued to fuel misconceptions regarding the power of ambidextrousness.

Can Being Ambidextrous Make You More Creative?
A Few Myths Busted

 

Jackson’s theories were not random ideas. They were derived from Paul Broca’s studies of brain lateralization that states that some cognitive brain activity is dominant in one hemisphere, and that each hemisphere was linked to the opposite hand.

No wonder people believed that using your less dominant hand would help activate both hemispheres of the brain leading to higher mental abilities.

That’s just the beginning…

Ambidextrousness and The Power of the Other Hand

In her book, The Power of Your Other Hand, Lucia Capacchione claims that writing and drawing with the non-dominant hand gives greater access to the right hemispheric functions like feeling, intuition, creativity and even spiritual wisdom.

These claims are based on the fact that the function of the right hemisphere is responsible for creativity.

Is there any truth to these claims?

“Although there are recurrent claims of increased creativity in left-handers, there is very little to support the idea in the scientific literature.”

This from renowned psychologist Chris McManus in his book Right Hand, Left Hand – The Origins of Asymmetry in Brains, Bodies, Atoms and Cultures.

 

The Truth About Learning To Be Ambidextrous
And Getting A Sharper Brain

 

While there is no hard data to prove that training your non-dominant hand can improve your mental prowess, there is now evidence to state that if you are born ambidextrous, you may have some mental health issues.

After 8 years of research, German psychologist, JB Sattler discovered that children who switched from their dominant left hand to a non-dominant right or the reverse did not see “a change in cerebral dominance but rather a multifaceted cerebral disturbance or damage”.

The psychologist noted that ambidextrous children even had decreased memory for all three areas of information processing – encoding, store and recall.

Sattler said: “Ambidexterity is therefore neither a goal to aspire to nor is it a gift from God. Instead, it is first and foremost the mark of brain damage.”

 

It May Sound Crazy, But It’s True!

 

A study published in the 1998 edition of Neuropsychologia confirms Dr. Sattler’s research.

In this study around 12,770 children were tested for their verbal, non-verbal, and mathematical ability and reading comprehension skills. They found that ambidextrous children had lower test scores as compared to those who were left-handed or right-handed.

Need more proof?

Another independent study led by Alina Rodriguez from Imperial College London showed that ambidextrous children exhibit higher symptoms of Attention Deficit Hyperactivity Disorder (ADHD).

Ambidextrousness may also have a lasting effect on adults as well.

In the creatively titled paper “Handedness and intellectual achievement: an even-handed look”, Michael Corballis reveals that ambidextrous adults perform more poorly on IQ tests (arithmetic, memory, and reasoning).

Ambidextrousness May Actually Harm Your Brain

 

Here’s why:

For right-handed or left handed people most of their brain activity is localized in the opposite part of the brain. So your brain can easily access information through the majority of one hemisphere.

For ambidextrous people information has to flow back and forth between both hemispheres of the brain through the Corpus Callosum.

This can be a big problem.

This rapid transfer may lead to mental dysfunction in some cases.

 

Are There Any Possible Benefits to Ambidextrous Training?

 

Yes, though they are not as dramatic as advertised.

Mr. Corballis writes that it’s possible to train your non dominant hand for artistic purposes – like playing the piano for example.

Other than that, there are no studies to prove that becoming ambidextrous can improve brain function.

But what about improved memory?

Ambidextrousness and Memory: A Genetic Connection

 

Ambidextrous tendencies has been associated with improved memory.

But here’s the catch:

To reap even the slightest memory benefits of ambidextrousness, you would be need to have at least an ambidextrous parent or sibling.

A 2001 study shows that families with one-left handed member may have better episodic memory rather than semantic memory.

Which means they have a better time recalling the context of the story rather than the facts present in the story.

The Only Trick You Need To Know To Make
Both Sides of Your Brain Work

 

There is one guaranteed method to improve both your episodic and semantic memory as well as autobiographical memory, spatial memory and procedural memory.

One more thing..

This method won’t be painful and labour intensive as using your non dominant hand.

Okay here it is:

Creating Memory Palaces the Magnetic Memory Method way.

Memory Palaces have the unique characteristic that all other memory techniques can be used inside of them (not the other way around).

So if you need to store a massive amount of information, Memory Palaces engage both hemispheres of the brain.

How do they do this?

Memory Palaces require a great deal of creative visualization, therefore it helps to activate your right hemisphere associated with creativity.

You need more than one Memory Palace and as many as possible. That way you can revisit the technique to recall tons of information.

A Direct method To Improve Your Memory

 

Learning to use your non-dominant hand to improve your memory can be a bit wasteful. You would have to spend days and weeks practicing to write with your other hand instead of focusing on what you need to learn.

While this may be fun, it’s not useful.

Memory improvement training should always be linked to memorizing information that will immediately improve your life.

Using the Magnetic Memory Method is great because, once you’re rolling, good memory abilities get you more time.

More time means you can practice memory enhancing techniques more often.

And that means experiencing better memory, better focus, clarity and concentration.

Ambidextrousness might be fun to develop if you take caution.

But, as we’ve seen, developing your memory is far more valuable!

    Another great article Anthony! I’ve been interested in this for a long time as my husband is multi handed. He does certain things with one hand (eg cuts bread, meat etc with left hand) and other things with the other hand (eg writes – he says because he was made to at school). His son is left handed. Fascinating about the link to memory. I’ll tell him he needs to do a memory course!

    • Thanks for this, Rosemary, and interesting to learn about your husband’s experience.

      How is your husband’s penmanship?

      Thanks for recommending that he take a memory course. There are many out there to choose from, to be sure. Is there any particular area of memory he would benefit from improving the most? (I.e. for language learning, names, facts, etc.?)
