The Difference Between
Being Left-Handed and Right-Handed
About 90 percent of the world’s population is right-handed and only 10 percent is left-handed. It is exceptionally rare for a true ambidexterity. Most left-handed people develop some mixed-handedness by living in a world where most everyday objects are for right-handed people (Balter, 2009).
Balter says “one researcher hot on the trail of these issues is Natalie Uomini, an archeologist at the University of Liverpool in the United Kingdom” (2009). Uomini states that handedness does not mean that one hand is more dominant over the other. She rather says that “both hands have different but equally important manual dexterity whereas ...view middle of the document...
The newer view of handedness is not a simple preference for one hand because the two hands actually work together in more suitable ways. For example, when writing, it is not a simple matter of one hand being dominant and writing on the paper. For right-handed people, the left hand is involved in important ways. It grips the paper and provides the context from which the right hand operates. With that being said the right hand appears more specialized for finer movements and the left for broader, contextual movements (“Handedness”, 2012).
The division of labor in the brain is the most commonly accepted theory of handedness. The premise of this theory is that both speaking and handiwork require fine motor skills. Having one hemisphere of the brain do both would be more efficient than having it divided up. If all the functions were carried out in both hemispheres the size of the brain and its energy consumption would increase. “Since in most people the left side of the brain controls speaking, right-handedness would prevail. It also predicts that left-handed people would have a reversed brain division of labor” (“handedness”, 2012).
There are some advantages in sports when it comes to be left and right-handedness. The advantages to players in one-on-one sports such as tennis, boxing, fencing, and judo is that in a population contains ten percent left-handers and ninety percent right-handers. When playing, about ninety percent of left-handers play his or her games against right-handed opponents and is well-practiced at dealing with this challenge, and ninety percent right-handers play their games against other right-handers. So when they are faced with a left-hander they are less practiced. When two left-handers compete against each other, they are both likely to be at the same level just like two right-handed opponents. “This explains why a disproportionately high number of left-handers are found in sports in which direct one-on-one action predominates (“Handedness”, 2012).
Other sports-specific factors may increase or decrease the advantage left-handers usually hold in one-on-one situations. Such as baseball,...
