Cross-dominance is also known as mixed-handedness and occurs when a person favours one hand for certain tasks and the opposite hand for other things. A person who is cross-dominant may also be stronger on the opposite side of the body that they prefer. A right-handed person may be stronger on the left side.

In human biology, handedness is the better, faster, or more precise performance or individual preference for use of a hand, known as the dominant hand. The incapable, less capable or less preferred hand is called the non-dominant hand.

While your dominant hand excels at precision movements, your non-dominant hand has better stability. That’s why someone who’s right-handed might hold a package in their left while opening a door with the right. “It’s not only because your right hand is better at using the key,” Philip said.

If you’re going to start writing with your non-dominant hand, you need to be committed to the training. That means it’s something you’re going to need to work on every single day.

Because we write from left to right, right handers pull the pencil, writing away from their body while left handers have to push the pencil, writing towards their body. Teaching left handed people to write the same way as right handed people can make handwriting slow, uncomfortable and messy.

There have been several theories over the years about why some people favor their left hand. A study published last year found that right- or left-handedness may have nothing to do with the brain — instead, it could be determined by gene activity in the spinal cord while you are in the womb.

Lefties make up only about 10 percent of the population, but studies find that individuals who are left-handed score higher when it comes to creativity, imagination, daydreaming and intuition. They’re also better at rhythm and visualization.

While some reasons for the differences in thinking and functioning may be genetic and anatomical, left-handedness is behavioral as well. Things left-handers do differently are often influenced by the societal implications of having a dominant hand that differs from the general public.

Lady Gaga. Even big fans of Lady Gaga might be surprised to know that she’s a lefty. That’s because when she plays guitar she does it right-handed. But if she signs an autograph, or sits down to write another pop anthem, she’s doing so with a pen in her left hand.
