These reports have precipitated comparison between ASMR and synesthesia – a condition characterised by the excitation of one sensory modality by stimuli that normally exclusively stimulates another, as when the hearing of a specific sound induces the visualization of a distinct color, a type of synesthesia called chromesthesia. Thereby, people with other types of synesthesia report for example 'seeing sounds' in the case of auditory-visual synesthesia, or 'tasting words' in the case of lexical-gustatory synesthesia.
Another article, "Autonomous Sensory Meridian Response (ASMR): a flow-like mental state", by Nick Davis and Emma Barratt, lecturer and post-graduate researcher respectively in the Department of Psychology at Swansea University, was published in PeerJ. This article aimed to 'describe the sensations associated with ASMR, explore the ways in which it is typically induced in capable individuals ... to provide further thoughts on where this sensation may fit into current knowledge on atypical perceptual experiences ... and to explore the extent to which engagement with ASMR may ease symptoms of depression and chronic pain' The paper was based on a study of 245 men, 222 women, and 8 individuals of non-binary gender, aged from 18 to 54 years, all of whom had experienced ASMR, and regularly consumed ASMR media, from which the authors concluded and suggested that 'given the reported benefits of ASMR in improving mood and pain symptoms...ASMR warrants further investigation as a potential therapeutic measure similar to that of meditation and mindfulness.'
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.
“Our research studies consistently show that ASMR is a relaxing, calming sensation that increases feelings of social connectedness,” Giulia Poerio (a co-author of the study), told Newsweek. “Importantly, we found that ASMR videos produce significant reductions in heart rate in people who experience ASMR. So we now have more objective evidence of the idea that ASMR is relaxing. It’s not just people telling us that ASMR makes them feel relaxed—their physiology is telling us the same thing too.”
Some ASMR video creators use binaural recording techniques to simulate the acoustics of a three-dimensional environment, reported to elicit in viewers and listeners the experience of being in close proximity to actor and vocalist. Binaural recordings are usually made using two microphones, just like stereo recordings. However, in binaural recordings the two microphones tend to be more specially designed to mimic ears on humans. In many cases, microphones are separated the same distance as ears are on humans, and microphones are surrounded by ear-shaped cups to get similar reverb as human ears.
The majority of the ASMR community online is focused on ASMR videos. These are videos which are designed specifically for triggering people’s ASMR. They are often very relaxing, even if they don’t trigger your ASMR reaction. Most of the videos you will easily find on You Tube are what is called intentional ASMR videos, but there are also unintentional videos. Unintentional videos are videos that were originally made for another purpose but just happen to provide ASMR triggers for some people. Many ASMR video creators are expert at creating guided meditations, however production values vary greatly from video shot from iPhone cameras to complete 3D sounds and special effects.
Among the category of intentional ASMR videos that simulate the provision of personal attention is a subcategory of those specifically depicting the "ASMRtist" providing clinical or medical services, including routine general medical examinations. The creators of these videos make no claims to the reality of what is depicted, and the viewer is intended to be aware that they are watching and listening to a simulation, performed by an actor. Nonetheless, many subjects attribute therapeutic outcomes to these and other categories of intentional ASMR videos, and there are voluminous anecdotal reports of their effectiveness in inducing sleep for those susceptible to insomnia, and assuaging a range of symptoms including those associated with depression, anxiety, and panic attacks.
