"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."
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.
The term ASMR was coined by a woman named Jennifer Allen in 2010. It was around that time that she ran across a group of people on a steadyhealth.com forum who described a sensation she herself had experienced, but which no one seemed to understand well. Frustrated by the lack of community organization on that forum, she created a Facebook group called Autonomous Sensory Meridian Response Group. The group name was one that she believed captured the key characteristics of what’s now known as ASMR. She wanted to create a community that would bring together people who had also been experiencing this sensation. She consciously created a term that she felt people would be comfortable using: one that sounded objective, clinical, and impersonal. Soon after, a worldwide community began to take shape.
Jacob Daniel is clearly a savvy child – although excitable and eccentric, he talks soberly about safety on YouTube, clapping his hands as he tells children to “be, be safe”. He tells kids to use fake names, access their email with VPNs, and avoid making custom Skype calls with viewers. For all his intelligence, however, Daniel is still a child. He and Prunkl show off a series of wigs they play with at home – he dons a purple one with red horns; Prunkl shows me her doll. They talk excitedly about the pranks they play on the public, wearing the wigs to order food in take-away shops.
Many of those who experience ASMR report that some specific non-vocal ambient noises are also effective triggers of ASMR, including those like the sound of rain, fingers scratching or tapping a surface, the crushing of eggshells, the crinkling and crumpling of a flexible material such as paper, or writing. Many YouTube videos that are intended to trigger ASMR responses capture a single person performing these actions and the sounds that result.
