It seems the ability to listen and follow two different sets of input into each ear may be genetic.
Researchers at the NIH's National Institute on Deafness and Other Communication Disorders (NIDCD), during the years 2002 through 2005, studied identical and fraternal twins, in attendance at the national twins festival in Twinsburg, OH.
In total 194 same sex pairs of twins, 138 identical and 56 fraternal, participated. After first determining their hearing to be normal, a variety of tests were performed.
Researchers concluded, in an article in the August 2007 issue of Human Genetics, that, ".... in all but the filtered-words test there was a significantly higher correlation among identical twins than fraternal twins, demonstrating a strong genetic component in auditory processing.".

I'm glad you posted this. Would have been a shame to have missed this informational gem. This is one of those items you have in mind when you say, "You learn something new every day."

Why don't we see more of this on cable TV news? Oh, I forgot. Paris Hilton is suing her manicurist for a mistreated hangnail.

Fantastic!

Now I have some ammo in the argument of why my fraternal twin brother did better than me in high-school calculus... our auditory processing was different! Aha!

Selective analysis? Perhaps.

Many years too late for our parents to care about my report cards? Most likely..

Amazing Story Karen, I cannot wait till they come up with a study on Teenagers Selective Hearing. My Kids, cannot pick up words such as Take out the trash, Clean your room, Do the Dishes, Do your Homework. But have the uncanny ability to distinguish at 40 paces between the sound a $20.00 dollar bill makes when I place it on my dresser to the psychic phenomena of hearing the phone ring before it actually does. So much we do not know about the human body.
