Tactile Modulation of Emotional Speech Samples

Table 4

Pairwise comparisons between the speech samples within the four concurrent tactile stimulation categories. In each cell there is Wilcoxon’s T value, stars to indicate the P value, the emotional content of the speech sample rated as more pleasant, and Cohen’s D value.

Concurrent tactile stimulation	Emotional content of the speech sample
	Positive versus neutral	Positive versus negative	Neutral versus negative
	T = 3.0**	T = 2.9**
Speech only	Positive	Positive	ns
	d = 1.13	d = 1.21
Derived from positive speech sample	ns	ns	ns
	T = 2.5*	T = 2.4*
Static vibration	Positive	Positive	ns
	d = 0.97	d = 0.98
Derived from negative speech sample	ns	ns	ns

∗P < 0.05, ∗∗P < 0.01, ∗∗∗P < 0.001, and ns: non-significant.
