The changed of score, degree of freedom (df), t and p-values, and size effects (Cohen’s d) are presented. The p-values below 0.05 are highlighted in italics. CS1 = 45:60 BB:AT ratio; CS2 = 30:60 BB:AT ratio; CS3 = 20:60 BB:AT ratio. BB = binaural beat, AT = autonomous sensory meridian response trigger, CS = combined stimuli of BB and AT, score = mean ± standard deviation.
