摘要

Autonomous sensory meridian response (ASMR) is an illusory phenomenon of tingling sensations and relaxation triggered by audiovisual stimuli without physical touch. This study investigated sensory mechanisms underlying individual differences in ASMR, focusing on affective touch sensitivity and interoceptive accuracy. Forty-six participants were engaged in tasks to evaluate tingling intensity via real-time ratings during ASMR videos, assess affective touch sensitivity through pleasantness ratings of gentle stroking at various velocities, and measure interoceptive accuracy using a heartbeat counting task. The results showed significant positive associations between tingling intensity and affective touch sensitivity, with stroking velocities in the optimal range for C-tactile afferent activation (3–9 cm/s) eliciting highest pleasantness ratings. Multiple linear regression further revealed that affective touch sensitivity significantly predicted ASMR tingling intensity in response to eating-related stimuli, highlighting the role of embodied social cues in ASMR responsiveness. No significant relationship was observed between tingling intensity and interoceptive accuracy, indicating that interoceptive processes play a limited role in ASMR. These findings emphasize the critical role of affective touch sensitivity in shaping individual ASMR experiences and suggest potential pathways for further exploration of tactile contributions to this phenomenon.
