"ASMR was recently brought to the attention of the public in 2010 (del Campo and Kehle, 2016). At this time, numerous online forums included discussions of a previously-unnamed feeling termed Autonomous Sensory Meridian Response, an unscientific name coined by Jennifer Allen. Over the next few years, descriptions of ASMR proliferated in the media, with some journalists referring to the tingling phenomenology as “brain orgasms” (e.g., Beck, 2013). To date, little research has been published on the phenomenon; indeed, only five peer-reviewed papers have been published on ASMR (e.g., Ahuja, 2013; Andersen, 2015; Barratt and Davis, 2015; del Campo and Kehle, 2016; Smith et al., 2016), only two of which included empirical data Barratt and Davis, 2015; Smith et al., 2016). Due to a dearth of experimental research on the subject, our understanding of the formal descriptive parameters of ASMR is highly limited. A recent survey study by Barratt and Davis (2015) was the first to find that whispering, close-up attention, and slow movements such as hair-brushing elicited tingles in over half of the 450 individuals with ASMR that they studied. The authors also found that other common ASMR triggers include listening to and watching an individual tap on various objects, watching an individual open a package, and watching an individual complete an intricate task, such as drawing, painting their fingernails, or applying make-up. There are several factors that distinguish ASMR from other atypical sensory experiences, such as frisson—the pleasurable tingling sensations that occur during an emotional response to music (often referred to as “chills”; del Campo and Kehle, 2016). The two phenomena are similar in that they both tend to occur while one is mindful and fully engaged with the triggering stimulus, they both involve an affective component, and both experiences are associated with large individual differences in triggering stimuli (Nusbaum et al., 2014; del Campo and Kehle, 2016). However, the two phenomena differ in that the tingles associated with frisson tend to spread rapidly throughout the body, whereas ASMR-associated tingles may last upwards of several minutes (del Campo and Kehle, 2016). Further, unlike frisson, ASMR experiences are often described as “wave-like” and “dynamic,” as the intensity of the tingles tends to morph throughout the triggering experience and may spread from the head and neck regions to the periphery of the body (Barratt and Davis, 2015; del Campo and Kehle, 2016). Finally, and perhaps most importantly for those who experience both ASMR and frisson, the tingling sensations associated with ASMR are often associated with relaxation and contentment (Barratt and Davis, 2015), whereas frisson experiences may be due to an exciting or emotionally arousing experience (del Campo and Kehle, 2016)."
