Mediation models of the outcome on an aDMTS (arbitrary Delayed Matching-To-Sample task) with 8 or 16-second delays (separately) and the mediators’ working memory, short-term memory, and delay aversion on a sample of TD and ADHD children. The presented models show that performance on the aDMTS task with delays of 8 s or 16 s was not mediated through working memory, short-term memory, or delay aversion. A clear direct negative effect between ADHD and the outcome on a CDL task with a delay (8 or 16 s) remained and increased in strength when a more dimensional ADHD-rating was used (DBDRS (Disruptive Behavior Disorder Rating Scale)-scores) or when untransformed data were analyzed. Unstandardized regression coefficients, because X is dichotomous [51]) are displayed for each relation. * p < 0.05. ** p < 0.01.
