Table 2.

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	1.90 (9.19)	t (29) = 1.13; p = 0.267 Cohen’s d = 0.21	t (29) = 2.04; p = 0.051 Cohen’s d = 0.62
Non-affective Touch	−3.47 (8.03)	t (29) = −2.37; p = 0.025 Cohen’s d = −0.43
