Table 1.

Effect size (Cohen’s d) and 95% confidence intervals for ΔHits following QMT (left) and OMM (right) in each class.

	QMT			OMM
	Cohen’s d	Lower CI	Upper CI	Cohen’s d	Lower CI	Upper CI
5th grade	0.48	−0.06	1.01	−1.04	−1.66	−0.39
6th grade	0	\	\	1.59	0.81	2.35
7th grade	0.47	−0.23	1.14	0.77	0.01	1.51
8th grade	0.69	0.01	1.33	1.05	0.29	1.79

Note: since no changes were observed following QMT in 6th graders (ΔHits = 0), effect size and confidence intervals were not computed. QMT = Quadrato Motor Training; OMM = One Minute Meditation; CI = 95% Confidence Intervals.
