(Press-News.org) A child's ability to distinguish musical rhythm is related to his or her capacity for understanding grammar, according to a recent study from a researcher at the Vanderbilt Kennedy Center.
Reyna Gordon, Ph.D., a research fellow in the Department of Otolaryngology and at the Vanderbilt Kennedy Center, is the lead author of the study that was published online recently in the journal Developmental Science. She notes that the study is the first of its kind to show an association between musical rhythm and grammar.
Though Gordon emphasizes that more research will be necessary to determine how to apply the knowledge, she looks forward to the possibilities of using musical education to improve grammar skills. For example, rhythm could be taken into account when measuring grammar in children with language disorders.
"This may help us predict who would be the best candidate for particular types of therapy or who's responding the best," she said. "Is it the child with the weakest rhythm that needs the most help or is it the child that starts out with better rhythm that will then benefit the most?"
Gordon studied 25 typically developing 6-year-olds, first testing them with a standardized test of music aptitude.
A computer program prompted the children to judge if two melodies — either identical or slightly different — were the same or different.
Next, the children played a computer game that the research team developed called a beat-based assessment. The children watched a cartoon character play two rhythms, then had to determine whether a third rhythm was played by "Sammy Same" or "Doggy Different."
To measure the children's grammar skills, they were shown a variety of photographs and asked questions about them.
They were measured on the grammatical accuracy of their answers, such as competence in using the past tense. Though the grammatical and musical tests were quite different, Gordon found that children who did well on one kind tended to do well on the other, regardless of IQ, music experience and socioeconomic status.
To explain the findings, Gordon suggested first considering the similarities between speech and music — for example, they each contain rhythm.
In grammar, children's minds must sort the sounds they hear into words, phrases and sentences and the rhythm of speech helps them to do so. In music, rhythmic sequences give structure to musical phrases and help listeners figure out how to move to the beat.
Perhaps children who are better at detecting variations in music timing are also better at detecting variations in speech and therefore have an advantage in learning language, she suggested.
Gordon is passionate about music education, which has declined nationally over the last few decades. She hopes her research may help reverse the trend.
"I've been thinking a lot about this idea ... Is music necessary?" Gordon said. "Those of us in the field of music cognition, we know — it does have a unique role in brain development."
Ron Eavey, M.D., chair of the Department of Otolaryngology, commented about the importance of music research — especially in Nashville.
"We live in Music City," said Eavey, director of the Bill Wilkerson Center and Guy M. Maness Professor of Otolaryngology. "Why is music appealing? We need to delve beyond peripheral organs into fundamental neuroscience."

Gordon's research was funded by a Vanderbilt Kennedy Center Hobbs Discovery Grant.
"Dr. Gordon's work is charting new and much-needed territory in an area that is increasingly captivating researchers and educators alike," said Elisabeth Dykens, Ph.D., director of the Vanderbilt Kennedy Center and the Annette Schaffer Eskind Professor.
VTT Technical Research Centre of Finland has developed an innovative magnetometer that can replace conventional technology in applications such as neuroimaging, mineral exploration and molecular diagnostics. Its manufacturing costs are between 70 and 80 per cent lower than those of traditional technology, and the device is not as sensitive to external magnetic fields as its predecessors. The design of the magnetometer also makes it easier to integrate into measuring systems.
Magnetometers are sensors that measure magnetic fields or changes in magnetic fields. The kinetic ...
Although gluten-free foods are trendy among the health-conscious, they are necessary for those with celiac disease. But gluten, the primary trigger for health problems in these patients, may not be the only culprit. Scientists are reporting in ACS' Journal of Proteome Research that people with the disease also have reactions to non-gluten wheat proteins. The results could help scientists better understand how the disease works and could have implications for how to treat it.
Armin Alaedini, Susan B. Altenbach and colleagues point out that celiac disease symptoms are triggered ...
Photosynthesis is one of the most important processes in nature. The complex method by which all green plants harvest sunlight and thereby produce the oxygen in our air is still not fully understood. Researchers have used DESY's X-ray light source PETRA III to investigate a photosynthesis subsystem in a near-natural state. According to the scientists led by Privatdozentin Dr. Athina Zouni from the Humboldt University (HU) Berlin, X-ray diffraction experiments on the so-called photosystem II revealed structures which were yet unknown. The results are published in the scientific ...
Many pollutants with the potential to meddle with hormones — with bisphenol A (BPA) as a prime example — are already common in the environment. In an effort to clean up these pollutants found in the soil and waterways, scientists are now reporting a novel way to break them down by recruiting help from nanoparticles and light. The study appears in the journal ACS Applied Materials & Interfaces.
Nikhil R. Jana and Susanta Kumar Bhunia explain that the class of pollutants known as endocrine disruptors has been shown to either mimic or block hormones in animals, ...

In an article published in Frontiers in Computational Neuroscience by Okinawa Institute of Science and Technology Graduate University's Professor Robert Sinclair, he suggests that there still is a place in science in modern times for the interpretation of results using rational numbers or simple ratios. In a time where supercomputers dominate scientific analysis, Prof. Sinclair argues that there is not enough attention being paid to the basic approaches to science of the past, which were able to profoundly illuminate our ...
JRC scientists have developed a new index to measure the magnitude of heat waves, in cooperation with colleagues from five research organisations. According to the index projections, under the worst climate scenario of temperature rise nearing 4.8⁰C, extreme heat waves will become the norm by the end of the century. Heat waves like the one that hit Russia in summer 2010, the strongest on record in recent decades, will occur as often as every two years in southern Europe, North and South America, Africa and Indonesia.
The Heat Wave Magnitude Index is the first to ...
WASHINGTON, Nov. 5, 2014—A new handheld probe developed by a team of university and industry researchers in the Netherlands and France could give doctors powerful new imaging capabilities right in the palms of their hands. The imaging system, which is described in a paper published in The Optical Society's (OSA) open-access journal Optics Express, shrinks a technology that once filled a whole lab bench down to a computer screen and a small probe about the size of a stapler.
The new device combines two imaging modalities: ultrasound and photoacoustics. Ultrasound ...
If you're inside, chances are you're breathing in low levels of indoor air pollution, a mix of volatile organic compounds and other gaseous substances that can accumulate in buildings and potentially make you sick. An article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, describes the latest in air-cleaning technology, including one approach based on a filter for the International Space Station.
Mitch Jacoby, a senior correspondent with C&EN, writes that in recent years, scientists have been gaining a better understanding ...
COLUMBUS, Ohio – A new study reveals the secret of how some fashion and beauty magazines continue to attract devoted audiences, even though they glamorize super-thin models that would seem to taunt normal-sized women.
The research suggests that some readers, rather than comparing themselves unhappily with the thin models, may derive "thinspiration": the belief that they can make themselves look just as attractive as the models they see in these magazines.
But this is not any kind of positive inspiration, said Silvia Knobloch-Westerwick, author of the study and ...
Around 5,000 cases of DCIS, a condition where cancerous cells are contained within the milk ducts of the breast, are diagnosed each year in the UK, with two thirds diagnosed through breast screening. If left untreated, up to half of DCIS cases could progress into invasive breast cancer, but it is not possible to say which ones, so all women are offered treatment.
This usually involves breast-conserving surgery (lumpectomy) and, to reduce the risk of the cancer returning, radiotherapy to kill any remaining cancer cells.
However, even with treatment up to one in five ...
