what determines wether you are right handed or left handed?

Answer 1

That's easy> your left side of the brain is in charged of all the movement in your body, while the right is in charged of all conecpt and processes of the mind (art, dreaming, thinking, etc..) So when we are growing it depends which process is given priority, that´s why you´ve heard of people that can write with both hands. If your question was aimed at genetics...answer is: NO. A left handed father will still generate right-handed children.

Answer 2

Even though a lot of people believe that the hand you write with determines if you're righty or lefty. The hand that you use for cooking, personal care, opening things, cutting things,etc.If you write with your right hand then there is a big change you're a right but that doesn't necessarily determine it.

Some causes of left handedness supposedly is hurting your right hand,having more testosterone or a child may look at his parents write with their left hand.

Answer 3

mmm, i think it is your genes. Studies indicate that left-handedness is more common in males than females. Approximately 8 to 15% of the adult population is left-handed. Left-handedness, in comparison to the general population, also appears to occur more frequently in identical twins.

Statistically, the identical twin of a left-handed person has a 76% chance of being left-handed, identifying the cause(s) as partly genetic and partly environmental.

Also people of South Asian, Eastern European, Southeast Asian descent are more left-handed than any other ethnic groups in the world, while people of Western European, Northern European, and African descent are less left-handed.

Studies show that people with long-term impairment of the right hand are more likely to become left-handed, even after their right hand heals. Such long term impairment may include from 6 months or more.

According to one theory, exposure to higher rates of testosterone before birth can lead to a left-handed child.This is the Geschwind theory, named after the neurologist who proposed it, Norman Geschwind. It suggests that variations in levels of testosterone during pregnancy shape the development of the fetal brain.

Left-handedness may be due to stress at birth.

A child simply learns from its environment and, as a result, the majority of people learn to be right-handed; the same goes for left-handed people, and this explains why left-handedness appears to be genetic

A common belief suggests that left-handed people are more intelligent or creative than right-handed people. While there is an unresolved debate within the scientific community on how to operationalize both intelligence and creativity, some studies have demonstrated a small positive correlation between left-handedness and creativity/intelligence.

If u want to know more, just type in "left handed" on wikipedia.org....thats where i found this info.

This is a very intersting Q, btw, i never thought of it!! lol

Answer 4

I've always accepted the testosterone theory for my own left-handedness.

Testosterone: According to one theory, exposure to higher rates of testosterone before birth can lead to a left-handed child.[citation needed] This is the Geschwind theory, named after the neurologist who proposed it, Norman Geschwind. It suggests that variations in levels of testosterone during pregnancy shape the development of the fetal brain.
The male brain matures later than that of the female, and the left hemisphere matures later than the right.

Testosterone suppresses the growth of the left hemisphere and so more neurons migrate to the right hemisphere. The highly developed right hemisphere is now better suited to function as the center of language and handedness. The fetus is more likely to become left-handed, since the right hemisphere controls the left half of the body. The theory goes on to tie the exposure to higher levels of testosterone and the resultant right-hemisphere dominance to auto-immune disorders, learning disorders, dyslexia, and stuttering, as well as increased spatial ability.

Answer 5

They say that the right side of the body is controlled by the left side of the brain, and the left side of the body is controlled by the right side off the brain. So that means left handed people are right most of the time!
I'm a righty and the rest of my family lefties. Mom switched me when I was very young learning to write. They say genetics but I think it is taught as you learn to write.

Answer 6

you could desire to attempt your eye dominance. coaching your vulnerable hand to shoot is plenty much less complicated than attempting to tutor your vulnerable eye to attempt. coaching a vulnerable hand to shoot will take you at maximum 2 sessions if no longer much less. I basically have been given finished coaching a woman the different day who's applicable exceeded and left eye dominant. She fought it interior the commencing up complaining each and each of how that she would desire to be taking pictures suitable exceeded, via the 0.33 end of the consultation, she replaced into taking pictures along with her left hand without problems. So, eye dominance try, there are a number of those. the only we often use is that this: a million. %. a aim far removed from you, and stand sq. to the objective 2. Take the two your palms, overlap the hands to style a diamond formed hollow between your index hands and your thumbs. 3. save your hands at once, palms in front of your waist 4. look on the objective with the two eyes open, just to make particular i like to close my eyes and shake my head area to area then reacquire the objective 5. develop your hands up and center the objective in that diamond formed hollow holding the two eyes open 6. deliver the palms on your face, the attention it comes back to is your dominant eye So once you're left eye dominant, you ask for left exceeded bow. suitable eye dominant ask for suitable exceeded bow. Left exceeded bow is held on your suitable hand and drawn at the same time with your left hand.

Answer 7

The determining factor is sexual preference. If you are gay you are probably left handed while heteros are always rights handed. No, seriously.

Answer 8

I think it has to do with hemispheric dominance of the brain. Only lefties are in their right mind. (it is a crossover thing, the right half of your brain controls the left side of the body---I have no idea why)

Answer 9

There are left handed animals in all quadrapedal species. It is an entirely natual phenomenon that is not unique to humans. Humans are only unique in one way: no other animals is stupid enough to force their young to switch hands.

And "David" is...intellectually challenged, to use a phrase that won't make him soil his diaper. His ignorance rivals Chicken George's.

Answer 10

Which hand you write with. Well, that's how I always thought of it. I guess it also depends on which hand you use to throw (when you throw with only one hand). But mainly which hand you write with.
