Methodology overview
How exercises map to constructs, and our commitment to publishing methodology as pilot data is generated.
Research & evidence
Built on constructs the field already validates.
Every cognitive exercise on the platform maps to a construct with a long literature — not an in-house metric we invented. We publish methodology as we generate pilot data.
What is the WelloWork research approach? WelloWork's training and assessments are built on five long-validated cognitive constructs — working memory, processing speed, attention, problem solving, and cognitive flexibility. We commit to publishing our methodology and pilot results, and we make no clinical or diagnostic claims about the biomarker side of the platform.
Which cognitive constructs does WelloWork measure?
- 01Working memoryN-back, span tasks · Baddeley, 1992
The capacity to hold and manipulate information in mind. Operationalised via N-back and span tasks with adaptive difficulty.
- 02Processing speedSymbol substitution · Wechsler, classic
How fast simple cognitive operations can be performed. Symbol-substitution paradigms; sensitive to sleep and fatigue.
- 03AttentionSustained & selective · Posner paradigms
Sustaining focus on a task and filtering distractors. Cued attention designs based on Posner-style paradigms.
- 04Problem solvingTower & Raven-style reasoning
Non-verbal reasoning under constraints. Adapted Raven progressive matrices and Tower problems.
- 05Cognitive flexibilityTask-switching costs · Monsell, 2003
The ability to shift between rule sets. Task-switching designs, with switch-cost reduction tracked over time.
