Test batteries

Cognitive test batteries

26 sets of tests in a fixed order, each with its standard settings. Start a study from one, and every participant takes the same tests the same way.

Research use only.

See the batteriesBrowse single tests

All batteries

Narrow the list by research area, time per participant or the device participants use. Tick Compare on two or three batteries to see them side by side. A battery takes the grade most of its tests reach. A minus means some tests have a lower grade, and a battery is never more than one letter above its weakest test. Every battery's grade

How a battery study works

  • The tests run in the order shown, with their standard settings. Changing, reordering or adjusting a test makes it a custom study. What test order does to scores
  • Each participant uses one credit, however many tests: $0.99 for academic research or $2.49 for commercial research. Every account starts with 10 free participants. Pricing
  • Each battery has a guide: how to give it, how each test is scored and how to cite it.
  • Each session is marked valid, needs review or invalid, with the reason. Study Quality Monitor
