Please help me with my Science project!?

Question

do left handeds have faster reaction times than right handeds?
Pls give me detailed information and if possible can you give me an experiment too? Its also ok if you just give me a site with information... Thank you very much

Answer 1

Thats a good project. I copied this stuff maybe it will give you an idea:
Left vs. right hand. The hemispheres of the cerebrum are specialized for different tasks. The left hemisphere is regarded as the verbal and logical brain, and the right hemisphere is thought to govern creativity and spatial relations, among other things. Also, the right hemisphere controls the left hand, and the left hemisphere controls the right hand. This has made researchers think that the left hand should be faster at reaction times involving spatial relationships (such as pointing at a target). The results of Boulinquez and Bartélémy (2000) and Bartélémy and Boulinquez (2001 and 2002) all supported this idea. Dane and Erzurumluoglu (2003) found that in handball players, the left-handed people were faster than right-handed people when the test involved the left hand, but there was no difference between the reaction times of the right and left handers when using the right hand. Finally, although right-handed male handball players had faster reaction times than right-handed women, there was no such sexual difference between left-handed men and women. The authors concluded that left-handed people have an inherent reaction time advantage. In an experiment using a computer mouse, Peters and Ivanoff (1999) found that right-handed people were faster with their right hand (as expected), but left-handed people were equally fast with both hands. The preferred hand was generally faster. However, the reaction time advantage of the preferred over the non-preferred hands was so small that they recommended alternating hands when using a mouse. Bryden (2002), using right-handed people only, found that task difficulty did not affect the reaction time difference between the left and right hands.

Answer 2

Wouldnt have thought so, comes down to the whole way that each individual has their own reaction time, therefore the hand that they use dominantly isnt a factor. Cant think of an experiment right now but will get back to you on that one

Answer 3

check out an experiment at the following link//:


http://pbskids.org/zoom/activities/sci/reactiontime.html


u can do this activity by taking the reading for both left handers n right handers..n then calculate their reaction time




besides u can also check out following links::
