This thesis evaluates the effectiveness of study components in order to aid in design refinements for a larger randomized controlled trial (RCT). A total of 38 post-secondary students with Attention-Deficit/Hyperactivity Disorder (ADHD) were randomized into a waitlist control group, or standard-length (45 minute) or shortened-length (15 minute) WM training group. Criterion measures included the WAIS-IV Digit Span (auditory-verbal WM), CANTAB Spatial Span (visual-spatial WM) and WRAML Finger Windows (visual-spatial WM). Transfer-of-training effects were assessed using indices of everyday cognitive functioning. Participants in the standard- and shortened-length groups showed greater improvements at post-test on auditory-verbal WM and reported fewer cognitive failures in everyday life than waitlist controls. Participants in the standard-length group showed greater improvements in visual-spatial WM at post-test than participants in the other two groups. Preliminary findings suggest that shorter training may have similar beneficial outcomes as documented for the standard-length training, indicating that a larger-scale RCT is warranted.
