TestMyBrain is a not-for-profit initiative dedicated to collaborating with researchers, educators, and citizen scientists throughout the world by providing accessible cognitive measurement tools. We began as a digital neuropsychological laboratory for studying face recognition in 2005, expanded into broader cognitive assessment in 2008, and now support digital cognitive assessment for some of the largest studies in health and science. Since 2008, we have collected data from over 3.7 million people worldwide.
We engage research participants as citizen scientists. People come to TestMyBrain to learn more about themselves and contribute to brain science. For visitors to our website (people like you!), we provide opportunities for you to test yourself via the research studies in the TMB Citizen Science Digital Laboratory (TMB Digital Lab).
Through participation from citizen scientists all over the world, we learn more about how the brain works, how we change as we get older, and how mental & physical health conditions impact cognitive health. Each study is designed to be brief and provide personalized feedback that is specific to you.
By making these research studies open and accessible to visitors of our site, we engage the public in brain and cognitive science research and share research data beyond the traditional research community.
If you’d like to take some brain tests or participate in a research study, visit the TMB Digital Lab. If you'd like to learn more about the importance of citizen science, are specifically looking for resources to test your face recognition skills, or would like to learn more about taking tests via the TMB Digital Lab visit Using TMB for Citizen Science!
For researchers, we provide access to resources that can help you integrate brief digital cognitive assessments into your research studies. We support a selection of validated digital cognitive tests that can be used to assess cognition in large, diverse samples, without the need for a trained administrator.
Our accessible web-based software is compatible with smartphones, tablets, laptops, and desktop computers, and we make our cognitive tests available (1) as open-source software, (2) as part of our accessible research toolkits, such as the TestMyBrain Digital Neuropsychology Toolkit, and (3) through our custom study infrastructure. See Using TMB for Research for more information about these resources.
For educators, we provide access to resources that can support classroom education and training. These resources are designed to facilitate learning through interaction and expose students to current research in the brain sciences. This includes access to the following resources:
We also have resources regarding face recognition ability and assessment. Learn more about all these tools via Using TMB for Education.
TestMyBrain began as a web-based face recognition testing site that was part of the Prosopagnosia Research Center (then at University College London, now at Dartmouth) in 2005.
In 2008, it was relaunched as TestMyBrain.org, based in the Psychology Department at Harvard University and with a broader emphasis on citizen science research that included diverse domains of cognitive and psychological function.
In 2012, TestMyBrain moved to Massachusetts General Hospital and Harvard Medical School, where the platform began to support collaborative work from researchers across health and science.
In 2015, the Many Brains Project ("Many Brains" a 501(c)(3) nonprofit) was launched to provide further support for partnerships with research and educators, as well as a sustainable model for supporting free and accessible digital cognitive assessment tools.
In 2016, the Laboratory for Brain and Cognitive Health Technology (BaCH Tech Lab) was established at McLean Hospital (part of Mass General Brigham) and Harvard Medical School.
Today, TestMyBrain is co-supported by Many Brains and BaCH Tech Lab at McLean Hospital. Since 2008, we have collected data from over 3.7 million participants in a citizen science framework, as well as supporting over 2,200 research studies in over 240 countries and territories through our toolkits and custom study infrastructure. TestMyBrain is supported by federal grants from the National Institutes of Health as well as contributions from research institutions, donors, and other funders.
