Are left-handers better at gaming?

Left-handed people often perform better than right-handers at fast or difficult tasks that involve lots of information or stimuli, new research suggests.

For instance left-handers might be better at playing fast computer games, talking while driving in heavy traffic and piloting a jet fighter – activities that need both hemispheres of the brain to process information.

Research shows that the left and right hemispheres communicate and work together better in left-handers, as information transfers from one to the other slightly faster and perhaps more efficiently.

Dr Nick Cherbuin from the Australian National University and colleagues report their findings in the November issue of the journal Neuropsychology.

He says the left-hander’s brain is wired slightly differently to the right-hander’s as it tends to be more symmetrical with larger and perhaps faster connections between hemispheres.

“As our brain ages we lose processing resources in the two hemispheres but left-handers may be able to cope better because the sharing of resource across their hemispheres is more efficient.”

The research found that on average those with faster connections were more efficient at performing tasks that require processing in two hemispheres.
