Is there a difference between left handed and right handed?

I found this information from Wikipedia.

"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.

In his book Right-Hand, Left-Hand,[18] Chris McManus of University College London, argues that the proportion of left-handers is rising and left-handed people as a group have historically produced an above-average quota of high achievers. He says that left-handers' brains are structured differently in a way that widens their range of abilities, and the genes that determine left-handedness also govern development of the language centres of the brain."

"Being left-handed can be an advantage in many sports. For example, in fencing, a right-handed fencer is more accustomed to facing another right-handed fencer simply because being right-handed is more common. A left-handed fencer is also more accustomed to facing a right-handed opponent for the same reasons. Therefore, when a right-handed fencer faces a left-handed opponent, the right-hander is not as used to fighting a left-hander as the left-hander is used to fighting a right-hander, causing a slight yet noticeable advantage. The same advantage may be present for most one-on-one or face-to-face sporting events. Baseball is particularly suited to left-handed hitters for three reasons: left-handers are already a step or two closer to first base in their batter's box before they even hit the ball so are more likely to beat out close plays; many baseball parks have shorter right field fences which gives left-handed sluggers a few more home runs that would otherwise be outs; and finally, most pitchers are right-handed which gives the left-handed hitter a better angle to see the ball and causes curve and sliding pitches to move towards them, rather than away. That is why a good switch hitter is considered valuable."

"According to this theory, right-handed persons are thought to process information using a "linear sequential" method in which one thread must complete its processing before the next thread can be started.

Left-handed persons are thought to process information using a "visual simultaneous" method in which several threads can be processed simultaneously. Another way to view this is such: Suppose there were a thousand pieces of popcorn and one of them was colored pink. The right-handed person — using the linear sequential processing style — would look at the popcorn one at a time until they encountered the pink one. The left-handed person would spread out the pieces of popcorn and visually look at all of them to find the one that was pink. A side effect of these differing styles of processing is that right handed persons need to complete one task before they can start the next. Left-handed people, by contrast, are capable and comfortable switching between tasks. This makes them appear (to the right-handed majority) as if they do not finish anything. Alternately, left-handed people have an excellent ability to multi-task. Perhaps the anecdotal evidence that suggests they are more creative stems from this ability to multi-task.

Right-handed people process information using "analysis", which is the method of solving a problem by breaking it down to its pieces and analyzing the pieces one at a time. By contrast, left-handed people process information using "synthesis", which is the method of solving a problem by looking at the whole and trying to use pattern-matching to solve the problem. Ultimately, being left handed is not an all or nothing situation. The processing styles operate on a continuum where some people are more visual-simultaneous and others are more linear-sequential. Also, it is very difficult to ascertain the way a human being behaves within the black box that is the brain. Whether this theory about processing styles is valid or not will be borne out by future experimentation."

I can't remember if this is for sure, but I think left handed people have a quicker reaction time than right handed people.

I hope this helped you :)

Left Handed Brain Differences

I believe the only difference is in which hand is the dominant one.

Psychologically: In the past left handed people (the minority) were taught to write with their right hand. That may have caused some psychological distress - it is harder to write with your other hand. Also maybe being in a minority caused some insecure feelings from being different.

I am almost positive there is no relation between handedness and brain hemisphere dominance - and certain that it has nothing to do with ones dominant astrological hemisphere.

.........* sigh *

I'm ambidextrous, basically i'm both handed. Originally i'm left handed but the f***ing teacher forced me to write in right hand, so there we go. In ancient times people with left hand were accused of being a...neither an alien or a witch (=_=.. crappy..). Now in some countries they still force us to write in right hand, like Vietnam.

People with left hand is more intelligent, creative, and much more psychic. They have another whole different type of structure in their brain, and they react more quicklier than right handed people. I heard that people with left hand make more money than right people do, but it's just a myth

Yes right hand works great for self satisfaction. Left hand with the help from the shoulder is need.

you use different parts of the brain. If you are right handed you are using the left part of your brain. If you are left handed you are using the right side of your brain

There is so much literature about L or R dominance in the world. Go to a uni library and you will see shelves of it.

Yes...if you are left-handed, you write with the left and use it more. If you are right-handed, then you write with and use the right more

left handed people are in their right state of mind. left and right are the same.... just different sides.

left handed ones have a rep. for being artistic
