This yr’s collection remaining of Strictly Come Dancing will function actor Rose Ayling-Ellis. Ayling-Ellis is the present’s first ever contestant who’s deaf. She has wowed Strictly viewers all through the collection and achieved glorious scores from the judges. However how is it doable that an individual who’s deaf can dance to music they’ll’t really hear?
Deafness or listening to loss normally entails an issue with the ear. Within the ear, tiny hair cells convert soundwaves into electrical alerts that journey to the mind. If these electrical alerts are lacking or decreased, the listening to elements of the mind will be unable to totally perceive sound.
However the mind is a wonderful downside solver. If sound is lacking, it’s going to use different sources of data to know what’s taking place round us. What an individual sees, and vibrations felt by means of the physique, might be notably useful sources of data for many who are deaf or hearing-impaired.
Are some brains wired for dance?
To learn to dance, the mind views the actions of others shifting to music and combines this with cautious counting. Many individuals with out listening to loss additionally do that when studying a dance – the steps are taught to beats or counts, that are then practised earlier than being put to music. For somebody with listening to loss, whereas the appreciation of the music differs, the training by means of commentary and counting is comparable.
As well as, the tactile data supplied by means of music may be very useful for individuals with listening to loss. As an alternative of listening to music, an individual who’s deaf might really feel the music, actually sensing the vibrations by means of their physique.
A course of referred to as cross-modal neuroplasticity additionally helps an individual who’s deaf to have the ability to dance to music. The mind is remarkably adaptable and can “repurpose” any mind areas that aren’t getting used. So, if the listening to areas of the mind should not getting used for responding to sound as a result of an individual is deaf, these elements of the mind might as a substitute reply to different issues, akin to visible or tactile data.
Applied sciences like sensory substitution units can additional help individuals with sensory loss. Sensory substitution is a method the place lacking sensory data is transformed into an alternate sense, to assist people who find themselves deaf or blind higher perceive the world round them.
One instance is a vibrating vest that enables people who find themselves deaf or have listening to loss to really feel sound by means of their pores and skin. The vest comprises a microphone which picks up sound. The know-how within the vest converts the sounds into vibrating patterns that the wearer can really feel on their torso.
Strictly Come Dancing: analysis exhibits that the luck of the draw issues in expertise exhibits
Because the mind is so adaptable and “plastic”, after some coaching to know which vibrating patterns match with which sounds, individuals with listening to loss can expertise the auditory world in a brand new means. Though we haven’t seen Ayling-Ellis use this sort of know-how on the present, comparable units have been utilized by dancers with listening to issues.

Ayling-Ellis is just not the one well-known determine to spotlight the exceptional functionality of a mind struggling to listen to. Composer Ludwig van Beethoven developed extreme listening to loss in mid-life, and seemingly used vibrational data in music to assist him proceed to compose.
As his listening to deteriorated, he’s reported to have favoured a piano constructed in such a means that the sounding board was related to the outer body, which conveyed highly effective vibrations to Beethoven’s fingers and thru the ground to his toes. These vibrations have been additional amplified by means of a steel resonator that Beethoven positioned on his pianos.
These examples spotlight the exceptional problem-solving functionality of the human mind, and the flexibleness with which the mind can method and overcome sensory challenges. Ayling-Ellis is definitely inspiring the nation and showcasing mind plasticity earlier than our very eyes.
