Table 1.

Descriptive statistics for each type of tactile stimulation (mean and standard deviation of the differential RMSSD score); simple t-test comparing the differential RMSSD score with the null level; and paired t-test comparing the differential RMSSD score in response to the two different tactile stimulations (affective touch vs. non-affective touch).

Type of Touch	Differential RMSSD Score	Simple t-Test (Null Level)	Paired t-Test
Affective Touch	0.35 (4.66)	t (29) = 0.41; p = 0.682 Cohen’s d = 0.07	t (29) = 2.71; p = 0.011 Cohen’s d = 0.66
Non-affective Touch	−3.51 (6.83)	t (29) = −2.81; p = 0.009 Cohen’s d = −0.51
