Note. Vspan = visual digit span, Aspan = auditory digit span, Rspan = reading span, Ospan = Operation span, "Max" = maximum span measure, "Cum" = cumulative span measure. N = 64. Data points were averaged across both span and span − 1 length lists. Scores on the diagonal represent Cronbach’s Alpha reliability coefficients, with the exception of the scores for the Ospan and Vspan tasks. For those tasks, Spearman-Brown split-half reliability estimates were calculated. Scores above the diagonal represent the correlations after correction for attenuation. These were not evaluated for statistical significance.
