An Instagram user who runs a repost account, meaning that they do not personally create any chalk-eating videos, told Motherboard in an Instagram direct message that they believe most people who make "chalk-eating" videos do not actually eat the chalk (The user asked that Motherboard withhold their account handle because certain members of the chalk-eating ASMR community have been bullied.)
I never realized this sensation had a name, but have been experiencing it from childhood. While studying about kundalini rising, I read the analogy of the thousand petal lotus blossoming on the crown of the head. I thought, ah, I know what that feels like! Sometimes reading letters from friends triggered it. Getting “picked” during a game of 7 Up triggered it. Having someone do the trick of pulling imaginary string from my palm triggered it.
According to Setz, this citation generally alludes to the effectiveness of the human voice and soft or whispered vocal sounds specifically as a trigger of ASMR for many of those who experience it, as demonstrated by the responsive comments posted to YouTube videos that depict someone speaking softly or whispering, typically directly to camera.
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.
