Hand Dominance: When Will I Know, What Should I Do?
Ninety percent of people, more or less, are right-handed, and around 10% are left-handed.
Hand dominance simply means that a person prefers to use one hand for most things involving motor skills, especially smaller, more intricate skills.
Ninety percent of people, more or less, are right-handed, and around 10% are left-handed. The tendency toward using a particular hand may be genetic, but there are multiple genes involved. It is not a straightforward trait like brown eyes. If you are left-handed, your child may or may not be left-handed too.
There is absolutely nothing wrong with children or adults that are left-handed. It was once believed that being left-handed meant there was damage to the brain that forced a person to use the left hand. We now know that is not the case.
People use the hand that they prefer for fine motor skills, as well as other things. A person can be left handed and do most things with that hand, from writing to throwing a ball to brushing their teeth. Other people do only some things with their dominant hand, whether it is right or left. The ability to use both hands equally is called being ambidextrous.
