  1. Significant values are in bold.
  2. Paired t-test was performed to examine within-group differences. Cohen’s d was calculated to estimate the effect size. Repeated measures analysis of variance (RM ANOVA) was used to examine group-by-time interaction. ASMR: Autonomous sensory meridian response, BB: Binaural beat.
