Correlations Between Measures

Measure	1	2	3	4	5	6	7
1. Mapping task (1-to-1)	0.70	0.69	0.69	0.61	0.70	0.53	0.47
2. Mapping task (uneven)	0.67	0.54	0.68	0.57	0.72	0.58	0.57
3. Spatial span (1-to-1)	0.67	0.66	0.86	0.73	0.60	0.51	0.41
4. Spatial span (uneven)	0.57	0.55	0.71	0.89	0.63	0.49	0.34
5. Name span	0.67	0.71	0.57	0.59	0.94	0.53	0.57
6. Counting span	0.49	0.56	0.48	0.44	0.47	0.79	0.38
7. Running span	0.45	0.56	0.38	0.31	0.55	0.35	0.92

Note. The correlations above the diagonal are raw, and those below the diagonal are partial correlations with age group variance removed. The measures used were the proportion correct across list length for the mapping task; the sum measure for spatial, name, and counting span tasks; and the mean number correct for running span. All correlations are significant at p < .05. In bold on diagonal: Cronbach's alpha measure of reliability based on data including all list lengths for each of 3–4 repeated measures.
