Cogstate’s computerized battery of rapid, reliable, simple and sensitive tests measure the cognitive domains affected by concussion and TBI, namely processing speed, attention, visual learning, working memory, visual motor function and executive function.
The construct validity of each test for cognitive impairment in concussion and TBI as well as the sensitivity of these tests to change in cognition has been demonstrated in the scientific literature. The tests have also been shown to be valid for use in professional athletes, different cultures and different language groups, with comparative/normative data available for both clinical samples and healthy controls. Study teams wishing to measure all or a subset of these domains can choose the tests that best suit their specific research questions. Each of the tests maintains excellent reliability across repeated testing and cross-sectional research designs.
The Detection test measures processing speed using a simple reaction time paradigm.
The Identification test measures attention using a choice reaction time paradigm.
One Card Learning Test
The One Card Learning test measures visual memory using a pattern separation paradigm.
One Back Test
The One Back test measures working memory using an n-back paradigm.
Groton Maze Learning Test
The Groton Maze Learning Test measures executive function using a maze learning paradigm.
