Being left-handed

Brain organisation

No-one has come up with a definitive reason for WHY some people are left-handed, but about 13% of the population around the world are, and it is thought to be genetic – it definitely runs in families. Researchers have recently located a gene they believe “makes it possible to have a left-handed child ” so if you have that gene, one or more of your children may be left-handed, whereas without it, you will only have right-handers – sorry! The good news is, that if you are left-handed yourself, you have that gene and will pass it on through the generations!

The way the brain works is incredibly complex, but this simplified explanation will give you some understanding of where our left-hand dominance comes from. The brain is “cross-wired” so that the left hemisphere controls the right handed side of the body and vice-versa and hand dominance is connected with brain dominance on the opposite side – which is why we say that only left-handers are in their right minds!

Brain organisation left hemisphere and right hemisphere

The left hemisphere (RIGHT HAND CONTROL) controls Speech, Language, Writing, Logic, Mathematics, Science, this is the LINEAR THINKING MODE.

The right hemisphere (LEFT HAND CONTROL) controls Music, Art, Creativity, Perception, Emotions, Genius, this is the HOLISTIC THINKING MODE

Effects of right brain dominance

This brain dominance makes left-handers more likely than right handers to be creative and visual thinkers. This is supported by higher percentages of left-handers than normal in certain jobs and professions – music and the arts, media in general. (See the results of our Lifestyle Survey of Left-Handers for our detailed findings) Left-handers are also generally better at 3-dimensional perception and thinking, leading, for example, to more left-handed architects than normal. Left-handers are also usually pretty good at most ball sports and things involving hand-to-eye co-ordination.

Image descriptionThe view that left-handers are clumsy and awkward is not down to their natural abilities, but being forced to use right-handed tools and machinery which is completely back-to-front for them.

    A very nice article.I want to tell some things about left handedness present in me which may convince you that I am an ideal lefty.here some things about me:
    1.I visualize things to understand them even in case of programming.
    2.my imagination power is very high.
    3. I am proud of my rapid eye movement done to understand things fast.
    4.when I am happy I enjoy every moment to its fullest.
    5.but when I am feeling bad…I am completely down..In that case each moment is very devastating for me.
    6.people say you should type with both hands…and I with left only.
    7.I am prone to fear of people….rejection by friends by society.
    8.currently have mild social phobia.so when somebody is explain to me..I don’t get what he/she is saying..Instead I find it good to understand things via Internet as nobody watches me at that time.
    9.now days it’s my habit to visualize even the most difficult thing.and if I can’t then my interest about that subject is lost.
    10.I over think about happy and sad moments.
    11,I cannot tease others but when others do it…I get very angry.
    Are these common things for a left hander?

    I have got a 3.5 yr child he does most of the activity in left hand in school but he has the habit of keeping his left thumb in the mouth playfully when he is handling a pencil he keeps left thumb in the mouth and handels pen in yhe right hand I am confused is he is left handed or right handed

    I have 46 year old Identical Twin Sons one of then is left handed and he has two children that are right handed, and his right handed twin brother ( whose wife is right handed also) has 3 children who are all left handed,I am thinking it may be because being identical twins they have 100% DNA. that’s why his children inherited his twin brother’s left handedness.

    Very interesting article. I’m left handed and some things I find (in my case) I prefer:

    1: Public Speaking (and generally getting my thoughts clearly out of my head into words).

    2: Learning visually (like watching a video) compared to being told how to complete a specific task.

    3: Listening to music while studying rather than silently study.

    4: Talking and describing stories with hands.

    I’m also aware that no one is completely right or left brained but I would say that I’m more right brained for sure.

    You do realize that the whole “brain dominance” is just BS pseudo-science that has no real scientific backing right?
