Psychologists have always assumed that the way emotions are organized in the brain is the same for all of us. But now, a new study suggests that left-handers process emotion in the opposite side of the brain to right-handers—which could change the way we think about and treat mental disorders.
Whether we're right-handed or left-handed can have a huge impact on what we subconsciously associate with good and bad. Right-handers, according to psychologists, see things to the right them as being better than things on their left.
Almost everybody has a dominant hand that they use, but it's actually a mystery why that is. After all, we can see both of our hands just as well, and there's no built-in reason why one should work better than the other. But some grabby parrots might hold the deep evolutionary reason behind handedness.
I don't know why you'd want to be a leftie, but at least we know the choice is out there if now. The magic causing the change of dexterity is called Transcranial Magnetic Stimulation, and is specifically intended for right-handers.
