Expectancy effects in the Autonomous Sensory Meridian Response

Area of Science:

• Neuroscience
• Psychology

Background:

• Autonomous Sensory Meridian Response (ASMR) is a subjective sensory experience.
• Despite popularity, empirical research on ASMR mechanisms is limited.
• ASMR is linked to specific auditory or visual stimuli.

Purpose of the Study:

• To investigate the neurophysiological mechanisms underlying ASMR.
• To examine the role of participant expectations and suggestibility in ASMR.
• To differentiate responses between ASMR-naïve individuals and enthusiasts.

Main Methods:

• Participants (ASMR enthusiasts and naïve observers) listened to ASMR-eliciting and non-eliciting audio clips.
• Participant expectations regarding ASMR were manipulated to assess placebo effects.
• Subjective sensory responses were recorded and analyzed.

Main Results:

• Naïve participants exhibited responses influenced by suggestive instructions (placebo effect).
• Experienced ASMR users demonstrated resistance to suggestive instructions.
• Initial ASMR exposure may shape somatosensory responses based on expectations.

Conclusions:

• ASMR perception can be influenced by expectation, particularly in novices.
• Experienced ASMR practitioners show less susceptibility to placebo effects.
• Findings suggest potential applications for ASMR in stress management techniques.
