Table 1.

Mean peformance rates (M) on the subtests of the WOMBAT with standard deviations (SD). Correlation with age and significance are given for each subtest.

Measure	M	SD	r	p
Test A (Digits Forward)	11.22	1.35	−0.30	0.12
Test B (Digits Backward)	7.67	1.81	−0.58	< 0.01**
Test I (Dots Sequence Forward)	10.22	2.02	−0.13	0.30
Test J (Dots Sequence Backward)	9.61	2.70	−0.21	0.20

STM Sum (A + I)	21.44	2.38	−0.28	0.13
WM Sum (B + J)	17.28	3.91	−0.42	0.04*
Verbal Sum (A + B)	18.89	2.63	−0.55	< 0.01**
Visuospatial Sum (I + J)	19.83	4.37	−0.19	0.22

P – values are one-sided due to expected one-way results in the correlations, as age typically influences working memory measures (Englund et al., 2014).
