"As ASMR has started to come to mainstream attention, researchers have finally begun trying to answer that question. Neuroscientists are now experimenting with fMRIs and electroencephalography to see if the brains of 'tingleheads,' as they are called, are any different than those who don’t tremble at the sight of napkin-folding. They’ve also surveyed tens of thousands of people who say they experience the phenomenon. So far there are intriguing—if limited—findings suggesting that ASMR may relieve some people’s symptoms of stress and insomnia, and that the brains of those who experience it may be organized a little differently."
Listening to a binaural recording through headphones simulates the binaural hearing by which people listen to live sounds. For the listener, this experience is characterised by two perceptions. Firstly, the listener perceives being in close proximity to the performers and location of the sound source. Secondly, the listener perceives what is often reported as a three-dimensional sound. This means the listener can perceive both the position and distance of the source of sound relative to them.
There is no solid data about ASMR, no published research studies — not yet. The term “ASMR” is nonclinical, coined in 2010 by a woman named Jennifer Allen who started an ASMR Facebook group and later became part of a team — along with Richard — that collected and analyzed anecdotal information about the sensation. Richard also notes the work of Bryson Lochte, a Dartmouth College undergrad who has used neuroimaging technology to study ASMR for his senior thesis but has not published his results.
It’s not really a physical feeling if that makes sense, but there is a powerful reaction to the sounds nonetheless, to the point where I’m instinctively arching my neck, and a feeling does wash over you that is truly unique, almost addictive. What I don’t fully understand is why my mind chose just now to react when I haven’t had anything close to an ASMR experience before. I’d say that I’ve just found the right trigger, but I’m even reacting to videos that did nothing for me in the past. Like something clicked in my head recently.
In addition to the effectiveness of specific auditory stimuli, many subjects report that ASMR is triggered by the receipt of tender personal attention, often comprising combined physical touch and vocal expression, such as when having their hair cut, nails painted, ears cleaned, or back massaged, whilst the service provider speaks quietly to the recipient. Furthermore, many of those who have experienced ASMR during these and other comparable encounters with a service provider report that watching an "ASMRtist" simulate the provision of such personal attention, acting directly to the camera as if the viewer were the recipient of a simulated service, is sufficient to trigger it.
