With digital neuropsychology, we’re opening the door to being able to understand cognitive information processing and brain functioning in many different environments, in many different contexts and in ways that will hopefully not only allow us to understand more about mental disorders, but also better inform treatment and interventions.

Features of our Cognitive Tests

  • All of our tests were designed and validated through our research platform, TestMyBrain.org.

  • Through TestMyBrain.org, we have developed more than 50 measures of cognition and tested 2.3 million people. Email info@manybrains.net for a full list.

  • Our tests are designed and optimized for the future of behavioral science: a future that is open, digital, and participant-centered.

We believe that openness is the key to high quality, replicable science as well as a democratic health care system. We are committed to creating cognitive testing software and normative datasets that can be shared with the academic, research, and clinical communities.

Modern Methods

We create cognitive tests based on technology that exists today. Our tests are broadly compatible with a range of devices and platforms including mobile devices, all vetted for accuracy of measurement through the research engine, TestMyBrain.org. Our team comprises top experts in psychophysics and behavioral measurement, to make sure that each test adheres to the highest possible psychometric and scientific standards.

Our work begins and ends with the patients, participants, and participant communities. Every test we create is vetted by the participants themselves to make sure that the test is clear, engaging, and serves the needs of participants. Through TestMyBrain.org, participants have rated each and every test and we use that data to create tests that maximize participant engagement and the value that participants derive from taking part in research.

All of our tests can be administered to participants remotely over the Web, outside of a lab or clinic. This means that participants can do the tests in any location that is comfortable and practical, on their own devices. Each test is compatible with a range of devices and platforms, and structured to be able to catch (and correct) common misunderstandings that participants might have so they don't impact data quality.

Each test has been validated and normed with respect to a dataset of at least 5,000 participants (and usually much more). These participants come from a broad range of demographic, social, and cultural backgrounds. They range in age from 10 years old to 89 years old. They represent almost every country and territory in the world. Normative data are available for interpretation of test scores.

Not every test is suited to every purpose; we are committed to working with researchers and clinicians to adapt tests to make them suitable for a range of settings and research purposes.
