How do you know if you are mixed handed?

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. For example, a mixed-handed person might write with their right hand and do everything else with the left one.

How are left-handed people's brains different?

The study, which also analyzed brain scans of 9,000 British subjects, found that in lefties, the parts of the right and left sides of the brain that process language work in better tandem. Whether that makes left-handers more fluent speakers is still to be investigated.

Why is left hand better than right hand?

Even in right-handed people the left hand can perform slow movements more precisely than the right, because of asymmetries in brain activity. Annotations.
