Left-handedness has long posed a challenge in many cultures, as nearly everything has been designed for right-handed individuals. I also have a relative who is left-handed, and the school saw no issues in that regard. He was an excellent student, graduated with top grades, and went on to a professional school where he had to use specialized instruments. The issue? Most of the instruments were, once again, designed for right-handed users.

He struggled significantly to find left-handed instruments, and he wasn’t alone. I also had a friend who was left-handed and enjoyed playing golf. Most golf equipment is similarly designed for right-handed players. Again, he faced difficulty finding left-handed golf clubs. But one time, he had a great chuckle when someone stole his golf clubs from the trunk of his car. “I wonder how surprised they’re going to be when they find out they can’t use those clubs because they’re made for a left-handed golfer,” He said with a glorious smile on his face.

Have you ever tried using your opposite hand to perform your daily activities? Do you believe that training your non-dominant hand can open up new creative channels or stimulate old, dormant brain regions? Recent studies show that the benefits of non-dominant hand training might be more useful than previously thought, yet more complex.

Have you ever thought about what would happen if you started using your “other” hand for everyday activities? Perhaps you have heard claims that training your non-dominant hand can unlock hidden creativity or tap into unused parts of your brain. The reality is more complex than these claims, but recent research has provided some interesting insights into what happens when we try to use our non-dominant hand.

What the Science Shows

The idea that using your non-dominant hand will suddenly make you more creative is largely a myth. As researchers have found, while blogs and self-help articles often promise dramatic cognitive boosts, the scientific evidence tells a different story. Any improvements you gain will likely be specific to the skills you practice, rather than providing a general creativity enhancement.

Actual Changes in Your Brain

When you persistently train your non-dominant hand, measurable changes occur in your brain. Studies using advanced brain imaging have shown that sustained practice with your non-dominant hand creates new neural pathways and strengthens existing ones. This process, called neuroplasticity, demonstrates your brain’s remarkable ability to adapt and reorganize itself.

For example, research on precision drawing with the non-dominant hand revealed increased functional connectivity among various brain regions involved in hand control and movement planning. Similarly, studies on learning to use chopsticks (granted, most of us rarely use chopsticks) with the non-dominant hand showed significant changes in brain activity patterns after just a few weeks of practice.

A Possible Schedule to Use

The following is based on research in this area, but it serves as a simple and potential guide for anyone who wants to test some of the research theories. This is not a specific training program for anyone, but a more recreational activity. Remember that research always has imperfections, and some of these results are due to the samples used, the areas where it was conducted, and the researcher’s own biases.

Training your non-dominant hand requires a structured approach, which begins with fundamental skills before advancing. If you think you will be turned into a Picasso or a best-selling author because of these exercises, you may be disappointed. There was only one Picasso, but you can possibly improve some things for yourself. Exactly what they will be, at this point, is an unknown. Daily practice of 15–20 minutes may lead to enhanced abilities.

Start with the basics (Weeks 1–2)
Write your name slowly with your non-dominant hand, followed by practicing the alphabet and basic words. The initial appearance of your writing does not need to be perfect. Back to that time in elementary school when you were first learning your alphabet, and how your handwriting had to be improved by repeatedly drawing circles and then letters. Using the non-dominant hand will be very much like the initial learning. This is the handwriting part of your exercise.

Now, draw basic shapes, including circles and lines, while concentrating on maintaining control rather than achieving perfection. The initial exercises help your brain learn fundamental motor patterns, which serve as a foundation.

Move into daily life (Weeks 3–4)
After gaining control of your writing movements, begin using your non-dominant hand for basic everyday activities. Begin by using your non-dominant hand to hold your coffee cup and use a spoon to eat during meals, starting with basic foods.

Do not attempt this while using hot liquids or foods in your non-dominant hand. We don’t want anyone to have an unpleasant experience. So, care is the watchword here. Spend daily intervals with your computer mouse positioned on the opposite side of your normal use. This technique helps you connect your practice sessions to actual, real-world applications.

Refine your skills (Weeks 5–8)
Progress to performing more accurate tasks with your non-dominant hand. The activities you should attempt next include threading needles, using scissors for basic cuts, and brushing your teeth. Add creative elements too — spend time drawing, painting, or playing instruments if you have them.

Master advanced coordination (Week 9+)
The last step involves performing complex tasks that will push your abilities to their limits. The brain development process benefits significantly from learning to use chopsticks, while activities like playing catch and writing whole paragraphs integrate all your learned skills. Progressively incorporate your non-dominant hand into your hobbies, cooking activities, and problem-solving tasks. But always proceed cautiously with every activity in which you will engage.

Will this program work for you? Only you can make that determination, and you are also the one who will decide whether you want to engage in this activity. It might be interesting, it might be useful, or it might be something you decide to toss aside. No harm.

I recently thought about the relationship between video game programming and brain activity. A new study suggests that playing video games is associated with improvements in brain activity and decision-making skills.

We begin with the observation that “historical neuroimaging studies suggest there may be beneficial effects of video game playing on attention, visuospatial, and memory abilities.”

Video games and brain function

A new study of college students provides some insights. For the brain imaging study, researchers recruited 47 subjects. All completed a questionnaire about video game playing for the past two years.

Researchers considered participants who played five or more hours weekly as video game players. Non-video game players engaged in gaming for less than one hour each week.

During functional imaging (MRI), the subjects performed a left-right moving dots task. They pressed a button in their right or left hand to indicate which direction the dots moved — or resist pressing either butting if no directional movement occurred.

The video gamers appeared faster by 190 milliseconds and more accurate by two percent with their responses compared with the non-video gamer group members.

On imaging, these differences appeared associated with changes in particular brain areas (including the thalamus, lingual gyrus, and supplementary motor area).

The researchers concluded that playing video games “potentially enhances several of the subprocesses for sensation, perception and mapping to action to improve decision-making skills.”

My take — Video games and the brain

I am not surprised that video gamers have better cognitive skills in some domains. Still, this study does not represent a randomized controlled experiment. In addition, whether the improvements in cognitive skills are relevant to real-world tasks is uncertain.

How much is video gaming time needed to improve select cognitive skills? And what are the downsides of video gaming besides addiction? The Georgia (USA) researchers are trying to answer these questions.

The researchers offer no conflicts of interest. Georgia State University provided funding.
