A peer-reviewed research study is the first to report physiological changes while individuals experience ASMR.
The publication is titled, “More than a feeling: ASMR is characterized by reliable changes in affect and physiology” and is authored by Giulia Lara Poerio, Emma Blakey, and Theresa Veltri from the University of Sheffield (UK) and Thomas Hostler from the Manchester Metropolitan University (UK). The research was published June 20, 2018 in the journal PLOS ONE.
The publication reported the results of two studies. The first study involved about 1000 participants watching videos and reporting how they felt. The second study involved about 100 participants watching videos, reporting how they felt, and having some physiological responses measured.
I will first summarize the methods and results of the first study, then summarize the methods and results of the second study.
