Backed by science.

Our programs are evidence-based, with studies published in peer-reviewed journals.  

In 2014, the Gibson Institute of Cognitive Research was established to conduct empirical research on cognitive training programs and assessments.  Findings are published and presented in peer-reviewed journals and conferences for the education, psychology, neuroscience and cognitive science communities.
