In Which Hand Do You Hold Your Cellphone?



A new study reveals that the hand you hold your cellphone to your ear with is determined by brain region dominance. Researchers found that left-brain thinkers use their right hand, while right-brain thinkers use their left.
The left side of the brain is said to be used for logical reasoning, whereas the right side is used more often for creativity.

The study, to be published in JAMA Otolaryngology-Head & Neck Surgery, found that 95 percent of people tend to be left-brain dominant.

The idea of the study was to be able to quickly find which side of the brain has the dominant language center. Most people who hold the phone on their right side will be left-brain dominant and their speech and language center will also reside there.

"We're pretty confident in our results," said the study authors, from the Henry Ford Health System in West Bloomfield, Mich."Basically, if your speech and language centers are in the left side of the brain—which for most people they are—a cellphone conversation is going to sound better in your right ear."
