Same. I tend to do round scratches with my hand at the top of the head crown to intensify the tingles. And like one dude (https://www.reddit.com/r/asmr/comments/3lrmyx/question_what_exactly_is_the_brain_orgasm_of_asmr/), my toes curl and eyes roll up. Rubbing hands, palms and inner wrist to be exact, against something or against each other. Same with feet.
Another article, published in the journal Television and New Media in November 2014, is by Joceline Andersen, a doctoral student in the Department of Art History and Communication Studies at McGill University, who suggested that ASMR videos comprising whispering 'create an intimate sonic space shared by the listener and the whisperer'. Andersen's article proposes that the pleasure jointly shared by both an ASMR video creator and its viewers might be perceived as a particular form of 'non-standard intimacy' by which consumers pursue a form of pleasure mediated by video media. Andersen suggests that such pursuit is private yet also public or publicized through the sharing of experiences via online communication with others within the 'whispering community'.
Plus, it’s logistically difficult to study a phenomenon that requires quiet and prefers solitude. As Smith points out, fMRI machines are noisy and EEG tests (which Smith’s team also tried) involve attaching “goop and sensors” to the scalp, potentially interfering with the ability to feel tingles. As Smith puts it, “the tools we have are not relaxing.”
In addition to the effectiveness of specific auditory stimuli, many subjects report that ASMR is triggered by the receipt of tender personal attention, often comprising combined physical touch and vocal expression, such as when having their hair cut, nails painted, ears cleaned, or back massaged, whilst the service provider speaks quietly to the recipient. Furthermore, many of those who have experienced ASMR during these and other comparable encounters with a service provider report that watching an "ASMRtist" simulate the provision of such personal attention, acting directly to the camera as if the viewer were the recipient of a simulated service, is sufficient to trigger it.
