handedness

toc = Handedness = 1373983873 = Definition: = a strong preference for using one hand or the other that develops between 3 and 5 years of age. p. 158 HGD, Chapter 7, pp.158-159

= Examples: = when a child is young he/she may have dominance in both hands but as they progress to ages 3-5 the dominance in one hand becomes stronger then the other resulting in a child writing, holding, and just using that hand more then the other.

With the dominance of the right hand, it can draw the left hand, and with the dominance of the left hand it can draw the right hand. This one is a picture of a dominate left hand pitcher. In his younger years he might have experimented with throwing with both hands but realized he throw much better with his left hand than his right, ultimately leading to the dominance of the left hand. An ordinarily exception to handedness is Micheal Vick. Vick is a predominately right handed person, as stated by himself, but for some odd reason he throws the football with his left hand. This goes to show that just because your good at more things with one particular hand, that doesn't mean your other hand doesn't have some type of dominance. In this case his "non-dominate" hand has made him a millionaire.

= Analogies: = Handedness is as natural as the rising and setting of the sun.

= Mnemonics: = Handlyness

Left-handedness stumps science They make up a stable fraction of the population, yet their presence is often invisible: left-handers. Yet despite decades of research, very little is known about why some people are left-handed. Scientists have proposed causes ranging from genes, to damage in utero, to an edge in fistfights to explain why southpaws make up 10 percent of the world's population.
