Many parents see their child switch hands during tasks, or show refined use of both hands and wonder if their child is ambidextrous. Maybe a child uses their left hand to throw a ball, but bats with their right hand. Maybe they kick a ball with their right foot, but hold a pencil with their left hand. Ambidexterity is a common question among parents of kids who switch hands in activities or don’t use one hand consistently.
Here, we are covering several aspects of ambidexterity. We’ll go over the difference between being ambidextrous and having mixed dominance. We’ll cover what it means when a child uses both hands to write or color. And, we’ll go over some activities to support a dominant hand.
How do you know if your child is ambidextrous or if they are showing signs of mixed dominance? This post will explain a little more about ambidexterity as well as mixed dominance and what it means in motor skills.
What does Ambidextrous Mean?
The definition of ambidextrous is use of both hands with equal refined precision and motor skill. This means that each side of the body is equally able to write with natural motor planning, fine motor control, strength, and refined motor movements.
According to the definition of ambidexterous, there is equal refinement and precision. You might think this means just the hands and fingers are involved with equal use of both sides. However, that’s not exactly the case.
Those who are truly ambidextrous may have equal use of hands, as well as feet, eyes, and even toungue motor skills.
An ambidextrous child will play naturally with toys using both hands. You might notice equal use of the hands and feet, or switching left to right or right to left during play, sports, school work, and other tasks.
When it comes to someone being ambidextrous and fine motor involvement, this can refer to:
- Scissor use
- Clothing fasteners
- Hand strength
- Brushing teeth and hair
- Many other every day tasks
Ambidextrous also refers to the feet too.
An ambidextrous person will be able to kick equally strong and with the same amount of force with both feet. They are able to “take off” from a running stance with equal feet placement, whether they start out running on their left foot or their right foot. Gross motor ambidexterity can be seen in:
- Kicking a ball
- Throwing a ball
- Catching a ball
- Among many other every day tasks
Ambidexterity can be observed in the eyes, too. Typically, all of us have one eye that is stronger, or a naturally dominant eye. We can complete a visual screening to identify this, or a visual exam may be in order.
Finally, an ambidextrous individual may show motor overflow movements with the tongue to both sides of the body.
Are you wondering about a child who uses both hands to write or perform tasks? Maybe you know a child who uses both hands equally and with equal skill. Perhaps your child uses one hand for specific tasks and their other hand for other tasks.
Mixed Dominance or Ambidexterous?
Just yesterday on The OT Toolbox, we discussed mixed dominance. In this post, we will cover more about true ambidexterity and what that means.
A child with mixed dominance demonstrates clear, stronger patterns based on the side of the body they are utilizing to complete the task.
For example, a child who is left hand dominant will develop a stronger fine motor pattern then a child who is not left side dominant but compensating for fatigue and is moderately adept at utilizing the left hand as a coping skill.
Is my child ambidextrous
A child who is truly ambidextrous will be equally as skilled at utilizing both sides of the body and it will look and feel natural to the child. Statistically, only 1% of the population is truly ambidextrous—it’s really very rare, and it is more likely that your child is experiencing mixed dominance patterns.
True ambidexterity requires both hands to be used with equal precision and there is no true preference in either the right or left hand for either both fine or gross motor tasks.
Can you make yourself ambidextrous?
This is an interesting question. Many times there is a perceived benefit to being ambidextrous, or switching hand or foot use during a task. Some perceived benefits might be:
- Switching hands when one is fatigued from use during a task
- Switching dominant sides during a sport such as baseball or softball to pitch with the other arm, batting from another side, dribbling to the other side when bringing up the ball during basketball, or kicking a ball with the other foot during soccer.
- Writing equal legibility with both hands
Actually being ambidextrous is different than teaching yourself to become ambidextrous.
To use both sides of the hand as a learned concept takes cognitive attention whereas natural ambidexterity occurs without thought. Because of the neuroplasticity of the brain, humans have the ability to teach themselves to use their non-dominant hand or side to complete tasks. It takes practice, practice, and more practice.
Read here on motor planning where we cover this concept.
Ambidexterity or Mixed Dominance?
Is my child ambidextrous? Isn’t that what mixed dominance is? These are two questions that therapists get asked frequently when evaluating a child for the first time for mixed dominance and other concerns. The answer is no, they are not the same thing.
This is a tricky area. Therapists recognize mixed dominance as a miscommunication or poor integration of the left and right sides of the brain and that’s how it’s explained to parents. However, there is a lot of information out there on this topic that may or may not be relevant to your child and her struggles— keep this in mind when Googling information.
It is more likely, that your child’s brain is utilizing the left and right sides for very specific motor skills such as writing, eating and throwing a ball. This can lead to motor confusion—this is where the poor integration and lack of communication between the left and right sides of the brain comes into play.
When the child is not utilizing one side of the brain more dominantly for motor patterns, confusion and poor motor learning occur leading to delays and deficits in motor skills.
It is unclear why the brain develops this way, but it does happen, and it is okay. In fact, it is easily addressed by an occupational therapist.
Ambidexterous Motor Development
I already touched on this a little, but a child with mixed dominance may switch sides for task completion when experiencing fatigue. Due to this, their motor development and precision is typically delayed.
The most common area that this is noted in is in fine motor development for handwriting. This is because the child is equally, but poorly skilled with both hands, and will switch hands to compensate for fatigue.
Motor delays may also be noticed later on when it comes to the reciprocal movements needed to throw/catch or kick a ball and when skipping. A child with mixed dominance may attempt to catch and throw with the same hand, hold a bat with a backwards grip, or stand on the opposite side of the plate when hitting.
They may also experience a moderate level of confusion, and frustration as they are unsure of how to make the two sides of their body work together leading to overall poor hand/foot-eye coordination skills.

Ambidextrous hands and eyes
If you have more questions and want to learn more on a dominant eyes and understanding how the eyes and hands work together during activities, you’ll want to check out our Visual Processing Lab.
It’s a 3-day series of emails that covers everything about visual processing, visual motor skills, and eye-hand coordination. We take a closer look at visual skills and break things down, as well as covering the big picture of visual needs and how the hands and eyes work together.
In the visual processing lab, you will discover how oculomotor skills like smooth pursuits make a big difference in higher level skills like learning and executive function. The best thing about this lab (besides all of the awesome info) is that it has a fun “lab” theme. I might have had too much fun with this one 🙂
