How do kids learn to write with two hands at the same time?

Assuming a child has never written with two hands at the same time, unless they were born to be ambidextrous. Or maybe this is an educational parameter kids have to learn at a young age, which then also leads to an increase in ambidexterity for children. <br><br>&#x200B;<br><br>edit: I found it super useful to read about how the two most common ways of coordinating the hands when writing with two hands at the same time compares to one another. Although it might be super boring to read about writing two hands at the same time for that long so I'm gonna put it in spoiler tags:<br><br>&#x200B;<br><br>>**Difficulties coordinating the two hands**<br>>When coordinating the hands to write with two hands at the same time, the primary problem most people encounter is that one hand gets ahead of the other. For example, when writing "dog", the left hand can be done writing "d" before the right hand is done writing "o". This results in a gap between two words that are supposed to be connected to each other. In two-handed writing, you have to make sure that you pull your hands back sufficiently at the end of every word so that the hands can be aligned for the start of the next word. Alternatively, the hands can be aligned at every letter, but this results in a pull and push motion at every word that slows down the handwriting. <br><br>>There are two ways of pulling back so that the hands don't get ahead of one another. The first is that the right hand only pulls back when writing the end of a word, and the left hand only pulls back when writing the start of a word. The second is that both hands pull back at the same time. Both options have advantages and disadvantages which is why both options can be used depending on whether there should be any space between two words or not. <br><br>>For the first option, a double pull back is required whenever a word is written with a suffix. For example, the word "dog" written as "doghouse" results in the right hand pulling back when writing "g" and pull back again when writing "s". This is a lot of work since the hands have to constantly pull back when writing. Alternatively, the hands can pull back together, so that the left hand pulls back when writing "g" and the right hand pulls back when writing "s" but then the pull back movement of the right hand is redundant and the pull back movement of the left hand is not necessary.<br><br>>For the second option, the right hand pulls back whenever writing a word and the left hand pulls back whenever writing a word. This results in a double pull back at every word, which is a lot of work. It is not necessary to pull back twice, so the pull back movement of the right hand is redundant. The advantage is that the hands no longer have to pull back depending on whether there is a space between to words or not. The pull back is increased when there is a space between two words, but the right hand doesn't have to pull back when writing a suffix. A pull back movement is necessary every time the hands have to align for any reason, which can be every letter, every word, or every sentence. <br><br>>Even though the hands constantly have to pull back when writing, the effort to pull back the hands is not a lot of work for someone experienced with writing with two hands at the same time. Since the primary effort is to move the hands in a writing motion, the secondary effort to pull back the hands at every word is easy to handle. However, when coordinating the hands to write with two hands at the same time for the first time, the pull back is the primary effort. The difficulty is to get the hands to be aligned at every word while also making sure the hands are moving in a writing motion. Therefore, the pull back needs to be very consistent to get the hands aligned properly, especially since the hands are not used to this type of movement.<br><br>>Even though the pull back movement is easy for someone who is used to writing with two hands at the same time, it is not efficient and slows down the handwriting. For example, when writing "doghouse" in normal handwriting, there is no pull back between "dog" and "house" which saves time. Even though it only takes a split second to write two pull backs for every word, it is still slower.<br><br>>Alternatively, the hands can be aligned every letter, so that the hands pull back at every letter and then move forward to write the next letter. This is faster since pull backs are shorter, but then it becomes a push and pull motion for every letter. Although it saves time at every word, it wastes time at every letter. <br><br>>For example, when writing "do", the right hand writes "o" and then pulls back, and the left hand writes "d" and then pulls back. Then the hands push forward to write "g" and then pull back again. For normal handwriting, the hands just write "dog" in one stroke without lifting the hands from the paper. For two-handed writing, the push and pull motion results in a gap between every letter, which results in a handwriting that looks disorganized and unprofessional. <br><br>>For a two-handed script, the push and pull motion wastes time at every letter and saves time at every word. For a two-handed print, even though the push and pull motion does not look professional in cursive, the push and pull motion wastes time at every letter and word.<br><br>>For a two-handed script, the pull back at every letter is faster than the pull back at every word since the pull backs are closer together. For a two-handed print, the pull back at every letter is slower than the pull back at every word since the pull backs are farther apart.<br><br>>For a two-handed script, it is better to pull back at every letter since the pull backs are faster but wastes more time. The pull back at every word is slower but wastes less time, but the pull backs are unstable since the hands need to pull back a longer distance. <br><br>>For a two-handed print, it is better to pull back at every word, since the pull backs are slower but wastes less time. The pull back at every letter wastes more time and is also unstable since the hands have to constantly move back and forth near the starting point of every word. <br><br>>Therefore, for a two-handed script, the pull back at every letter is better but wastes more time and for a two-handed print, the pull back at every word is better but is slower. Although the pull back at every letter is faster but wastes more time for two-handed script, the pull back at every letter can be eliminated for cursive. For two-handed print, the pull back at every word cannot be eliminated.<br><br>&#x200B;<br><br>&#x200B;
