ANOVA Summary Table for MD/TA and Reactivity and Effect Size for the Cognitive Tasks.

	F	p	TA (d)	MD (d)
Working memory for numbers	0.20	.15	−0.70	−0.59
Working memory for words	2.67	.10	−1.18	−0.58
Digit span forward	1.14	.28	−0.20	−0.13
Digit span backward	0.31	.57	−0.28	−0.09
Rapid number naming	0.83	.36	−0.22	−0.03
Rapid picture naming	1.28	.26	−0.32	−0.78
Letter number sequence	2.69	.10	0.21	−1.28
Quantitative concepts	0.45	.50	−0.83	−0.50
Block rotation	0.43	.51	−0.63	−0.29

Note: d is the standardized mean difference for the TA high to TA low and for the MD high to MD low. Negative d indicates that children with high reactivity obtained lower scores than children with low reactivity. MD = math disability; TA = typically achieving.
