CWMT, Cogmed Working Memory Training; PAC, Paying Attention in Class; WRF, Word reading fluency. All scores are expresses in a learning efficiency quotient. d¹ = difference between groups for the change scores post to baseline for both groups, divided by the pooled standard deviations of both groups at baseline. d² = difference between groups for the change scores follow up to baseline for both groups, divided by the pooled standard deviations of both groups at baseline.

^ap = < 0.005 (significant after Bonferroni correction); ^bp < 0.05.
