In another study, detailed in a forthcoming paper, Smith and colleagues tested 290 people who experience ASMR for what are known as the Big Five personality traits, and compared their results to those of an equal number of “matched controls.” Smith and colleagues found that ASMRheads scored higher on measures for what’s known as “openness to experience” and neuroticism and lower for conscientiousness, extraversion and agreeableness—findings the researchers say warrant more study.
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.
ASMR is usually precipitated by stimuli referred to as 'triggers'. ASMR triggers, which are most commonly auditory and visual, may be encountered through the interpersonal interactions of daily life. Additionally, ASMR is often triggered by exposure to specific audio and video. Such media may be specially made with the specific purpose of triggering ASMR or originally created for other purposes and later discovered to be effective as a trigger of the experience.
