BrainLabs measures three cognitive domains: reasoning, short-term memory, and verbal ability. We see these as basic building blocks of cognitive performance. While your C-Score is useful as a quick snapshot of performance, it is really made up of cognitive domains. Cognitive domains are independent, relying on different networks within the brain. While they may be correlated, we hypothesize that this is only because each domain relies on overlapping brain functions. This distinguishes our approach from IQ or "g" theories of intelligence, which propose that there is a single overall factor underlying the brain's performance (for more info, see the FAQ Does the C-Score measure IQ?).
The domains are:
You'll receive a score for each domain in your Brain Report after completing a challenge, with tips on what changes in each domain mean in your everyday life. Explore the science for more detail on the research behind these scores.
How are cognitive domains calculated?
Basically, your test scores are used to calculate domain scores, with each test contributing to one or more domains, depending on the nature of the test. See this FAQ for more detail: How are the test scores used to calculate the C-Score and cognitive domain scores?
Are these the only cognitive functions of the brain?
No way—your brain does a lot of stuff! Reasoning, short-term memory, and verbal ability are very important in almost any task considered "cognitive," but your brain performs a lot of other functions. For example, basic perception, emotional processing, and motor skills are not directly captured in these domains. So don't worry if one or more of your domain scores are low—while working to improve them will have wide-ranging effects, you certainly already have other strengths that are not captured in these scores.
