TABLE 1.

Accuracy and reaction time in CH-NATs vs. CH-PATs.

	CH-NAT		CH-PAT		P-value	Pooled SD	Cohen’s d
	Ave (SD)	Max K-S value*	Ave (SD)	Max K-S value*
0-back
ACC	0.90 (0.06)	0.17	0.88 (0.06)	0.17	0.441	0.06	−0.33
RT (ms)	574.45 (96.40)	0.1	559.73 (63.23)	0.12	0.679	81.52	−0.18
2-back
ACC	0.82 (0.07)	0.11	0.75 (0.09)	0.15	0.029	0.08	−0.87
RT (ms)	865.35 (128.02)	0.19	836.85 (132.36)	0.09	0.602	130.21	−0.22

The mean accuracy (ACC) and mean reaction time (RT) were calculated for both CH-NATs and CH-PATs. There is no significant difference in 0-back for both ACC and RT however, during 2-back CH-NATs performed significantly better than CH-PATs. P-values with < 0.05 are in bold italics to denote significance (Baddeley, 1998b). * K-S values are based on (α = 0.05 critical value of 0.41. SD standard deviation; K-S, Kolmogorov-Smirnov test.
