Study summary

Our primary aim is to determine whether a computerized working memory (WM) training program will help students with severe learning and attention problems, in terms of improving their WM. Additional aims are to determine whether the WM training will also result in improvements in the students' concentration and school work, and how long any beneficial effects will last (i.e., whether the students will continue to show improvements once the training program has stopped).

Read the detailed description

We have established a collaborative partnership between OISE, HSC, OPDS, and JVS to evaluate the effectiveness of a WM training program when conducted in a school setting. To determine whether the WM training program does improve WM, attention, behaviour, and/or academic achievement, we will compare its effects to those expected to result from two other intervention programs that focus on academic skills only: 1) a computerized software program known to improve math skills (Academy of Math®); and 2) extra, individualized tutoring in an area of academic weakness supervised by a trained and experienced staff person. We will assess WM, related cognitive abilities, ADHD symptoms, academic achievement, before and after intervention, and also at 3- and 6-month follow-up to determine whether any improvements are sustained and increased after the training has finished.

Interventions

  • OtherCogmed Working Memory Training Program.

    This program includes a set of visual-spatial and auditory-verbal WM tasks presented via the computer (see Appendix 1 for a description of these tasks). All tasks involve: a) maintenance of simultaneous mental representations of multiple stimuli; b) unique sequencing of stimulus order in each trial; and c) progressive adaptation of difficulty level as a function of individual performance. Training will require about 30 minutes per day, 5 days per week, for 5-6 weeks: participants are required to complete 90 WM trials on each training day. Training plans are individualized and are modified according to performance, but the typical plan includes 13 tasks, with 15 trials of 8 tasks each day.

  • OtherAcademy of Math

    This is an established evidence-based program designed to help at-risk learners (Grades K-12) develop mathematical proficiency by incorporating a mastery-learning approach to foster conceptual understanding, computational fluency, and strategic competency across 10 mathematical subject areas. Training is will require about 30 minutes, 5 days per week, for the same duration as the WM program (5-6 weeks), with a counselor or teacher acting as the training aide.

  • OtherSpecial Education/Individualized Tutoring

    Students in this group will receive an additional 30 minutes daily of individualized supplemental instruction in their area of greatest academic need.
