    Research Projects

    Improving Children’s Working Memory with Cogmed and Strategy Training

    •  The overall goal of this project is to improve memory and subsequent academic success of children suffering from memory deficits. We examine interventions designed to improve memory ability and academic performance in children suffering from working memory deficits.  A team of researchers and practitioners has been established consisting of academics specializing in memory, learning disabilities, and assessment, from the University of Saskatchewan, as well as members of the Greater Saskatoon Catholic Schools division, who have expertise in school and division programming, speech-language pathology, educational psychology, and special education (e.g., learning disabilities).  The aim of our initial study is to determine whether the working memory and academic performance benefits of teaching children working memory strategies will be amplified by Cogmed training, a computer-based working memory training program.

    Children's Memory for Pain: Improving Children's Coping via Forgetting of Biased Pain-Related Memory (BSC#: 03-1035)

    • The primary goal of this project is to understand how children remember and forget painful experiences, such as needles, hospital stays, and dental procedures. By understanding their memory for such experiences we will be able to improve treatment and management of pain, which will help children cope more effectively with future painful experiences or events.

    Memory Accuracy and Memory Distortion across the Lifespan

    • The primary goal of this program of research is to examine factors that produce memory accuracy and inaccuracy across the lifespan. We have examined the effects of practice on recalling remembered events, the effects of omitting information from practice, false serial position effects, and false memories. We are currently investigating whether adults can detect the veracity of children’s reports such as drawings of witnessed events, factors influencing forgetting, and the strengths and limitations of investigative interview protocols.

     Community-Based Research

    • We are currently working with community-based organization to learn about attitudes towards the criminal justice system as well as everyday memory concerns of older adults in long-term care facilities.
