Results of Experiment 2 (N = 34). (a and b) Time course of pulse rate and pulse wave amplitude throughout ASMR, Nature, and Rest periods (1 min for each). Bars represent averaged tingling and pleasantness ratings with standard errors of means. (c and d) Individual data for pulse rate and pulse wave amplitude. Thick lines indicate means of these measures. ***p < 0.001, **p < 0.01.
