Lefties are special I guess..... My case is weird reverse catholic my older sister is a natural lefty she taught me to right when I was 3 or four I copied her right down to the hand movement and became a FULL lefty, its my writing hand, but I can shoot lefty or righty and I eat chopsticks with my right. I still try to write with my right hand..... not too bad

Not sure how I missed this thread, but here is my thread on left handed people LINK

I am going to read this thread now, will return.....

Ok ok, I see your question.

I was always told I was left handed because I was born feet first. But I think it is a lot of what is taught. And even being "left handed" is 100% being a lefty. I am extremely left handed dominant. I use my left hand to eat, wash, bat, throw, write, fish, you name it my natural side is my left.

But some may just write left handed, or some will kick or even combinations of them. Which to me means, not all people are purely "right handed",

really its probably more chance than anything else.

The theory behind "right-hand dominance" is supposed to be that the half of the brain which controls the right side of the body is also the side of the brain which deals with speech, intellectual activity, etc.
So our human tendancy to be dominated by our intellects tends to carry "right-handedness" along with it.
I don't know the explanation for the exceptions.
Left-handed people tend to claim that left-handed people are more "intuitive" instead, and start listing all the left-handed artists, composers, etc.

my left hand life in a left hand thumbnail sketch:

kindergarten teacher tried to force me to be a righty (mid 70s')

1st grade teacher embraced my leftward ways (score!) never another teacher bothered me about it afterwards

I have always drawn and been musical, though i didnt learn to play the guitar till i was 16, still playing more than 20 years later and have picked up violin, drums, and a few other instruments along the way

im not that great at math, always hated it as well as homework in school, but i love reading about abstract math and science concepts

i do everything right handed except write and draw (maybe im not a 'true lefty' ?) but can switch if i want, though with not as good an accuracy most the time

i have two siblings from my mothers re marriage, one of which is a lefty, so i know my mom carries the lefty gene

i have always been called weird and strange by my peers and sometimes by ppl that dont even know me....seems to come with the territory of being left handed? (i personally dont think im all that peculiar but apparently my lack of mainstreamness is noticeable to some ppl)


i dont think left handers are superior....its natural that ppl want to think they are special for one reason or another......i personally think everyone is special because there is only one of them...

as for ambidexterity and such....i used to read a great deal on handedness and brain organization.....true leftys or true rightys are probably about the same in reaction time.....but ambi's have more accidents because there is more crosstalk in the brain which lengthens reaction time in a time sensitive situation.....and lefty's do tend to be more ambidexterous than righty's on average thus the common reports of lefty's having more accidents (not so much a result of being clumsy but of not having a strong side dominance)

im not sure if this is accurate but its supposed to be a left/right dominant test...

most of u seen before, its so classic like from psych 101...



also apparently most animals are left brain dominant and so use their right hand/claw


animals as diverse as frogs, birds, mice, rats, gerbils and marmosets tend to show more reliance on their left hemispheres in producing and recognizing their species' vocalizations. Even in humans, right-handed adults are more likely to show greater activity in their left cerebral hemispheres on language tasks. And the only situation in which chimpanzees show clear handedness is during pointing - when chimpanzees point, they tend to do so (around 2/3 of the time) with their right hands


thats pretty amazing chimps are also mostly right handed like humans, 66% of the time for chimps and like 90% for humans, lefthandedness and right-brainedness seems rare in nature

Then,at around a minute or so she changed to clockwise and then
back.

Very similar.
First she was turning anti-clockwise then turned clockwise, however, she stayed clockwise for me.
