Babies learn music while sleepingPosted by Riise Dowd on February 15th, 2021 () - Early screening and strategy for infants with hearing problems, and the capacity to computer-generate musical scores, are two completely different possible link between some off-the-wall” research. Until recently, little has been known about the perceptions humans have once they go into the world. Although adult perception has become extensively researched, how, as well as if, the brains of babies perceive patterns on the globe remained a mystery. That mystery may be a minimum of partially solved by an EU-funded research project, EmCAP, which brought together what many would consider an unlikely consortium, comprising both neuroscientists and music technologists. What project coordinator Susan Denham describes as blue-sky thinking” by her and her colleagues whenever they initially proposed the project led to experiments involving playing music to infants. Scanning sleeping babies In the experiments, sleeping babies were hooked up to an encephalograph (EEG), a musical instrument in a position to measure brain activity using electrodes put on the scalp. The babies were then played music - to be more exact, simplified tone sequences - to check what sort of patterns these folks were understanding of and if they would predict the thing that was coming next based on what went before. The babies were assigned sequences of sounds of various tone colour - different musical instruments, if you love - but all the same pitch. Occasionally, you play a sound of the different pitch watching the EEG to find out if they make a distinctive response to this deviant sound,” explains Denham. directory were done to ascertain if babies were understanding of rhythmic and melodic patterns, too. Denham says even though this form of technique may be used for decades on adults to measure pre-conscious detection of unexpected events, it's seldom been combined with newborns. The big advantage is that it could work even though somebody is unconscious. So the babies being asleep has not been a problem. Rocking inside cradle The effects were exciting, demonstrating newborns a a feeling of pitch from birth, and this has not been something learned through experience as had previously been thought. The experiments showed they may be even responsive to the beat in music. The bottom line is we receive the planet with brains which are continually trying to find patterns, and telling us if you have something unexpected we ought to understand,” says Denham. István Winkler, who conducted the baby research, concludes this capability allows babies to understand their environment and the important actors inside. The discoveries could be applied to developing early screening techniques and control of cognitive hearing difficulties. The screening currently used simply measures how hard of hearing individuals are instead of the nuances of their actual perceptions. Research is required to determine typical - and exactly how much variation there is certainly from it - to prevent false diagnoses whenever a baby is actually developing slowly,” Denham says. But then it must be possible to recognize defects at a very initial phase and treat them while the mental abilities are still malleable. New light on music cognition The researchers have thrown new light on music cognition and brought practical benefits to the music technologists involved within the project. While it remains unclear whether a ease of music is rooted as the name indicated, instead of nurture, it's clear that musical competence is a special human capacity, shared across ages and cultures.” says project partner, Henkjan Honing. Although the capacity to detect musical patterns exists from birth, music cognition develops throughout life. However, music cognition is influenced not so much by musical expertise, as by experience. According to Honing, Frequent paying attention to a particular musical genre allows listeners without formal musical training being experts in that musical style.” Computers mimic the brain Details revealed through the experiments in regards to the way mental performance checks and adjusts its expectations made it feasible to develop applications that mimic these processes. Researchers in EmCAP created a generic algorithm, basically a bit of smart software, in a position to detect violations of expected pitch and rhythmic structure, with tonality soon being combined with their list. We did the modelling at two levels, one looking to emulate brain function and perception in the simplified but nevertheless fairly detailed way, and also the other tailored more for practical utilization in music processing systems,” Denham says. What this may mean in practise, is the future continuing development of artificial cognitive music systems in a position to listen” to music and produce a score in real time showing which instruments play which notes. Project partner Xavier Serra shows that the next generation of music processors will be depending on algorithms that imitate how humans process music. Further projects are planned around the back of EmCAP, including one starting in March 2009, that will use sounds to detect behavioural patterns of living creatures. EmCAP was funded underneath the Future and Emerging Technologies (FET-Open) scheme of the EU's Sixth Framework Programme for research.Like it? Share it! More by this author
