Peer-reviewed Research Supports The Claims Made By Cogmed

Cogmed improves working memory and attention in daily life. Click the image to the right to read the peer-reviewed published review. The below table includes all of the studies that validate SOLELY the Cogmed Working Memory Training program and that have appeared in peer-reviewed, scientific journals. Several studies included are randomized, double-blind, placebo-controlled trials and many are investigations by research with no affiliation to Cogmed. To read summaries, click on the title of each published study.

We also provide a free webinar about Cogmed research hosted by clinical psychologists Dr. Charles Shinaver and Dr. Peter Entiwistle – see the upcoming schedule.

In addition to the published studies shown below, a table summarizing ongoing Cogmed studies can be found here. The software and protocol used in these studies is the very same as that used every day by clinicians in the Cogmed network around the world – review our research strategy.
