A structured screening for dyscalculia, the specific learning difference that affects how your brain processes numbers. Covers number sense, arithmetic fluency, and the cognitive foundations that support math.
Measures the core attention dimensions that differ in ADHD: sustained focus, impulse control, response consistency, and processing speed. Not a diagnosis, but a data-driven starting point for understanding how your attention works.
All 26 tests across every domain. Processing speed, working memory, executive function, fluid reasoning, verbal comprehension, dyscalculia, and ADHD indicators. Get an AI-generated report analyzing your complete results.
How quickly you process and respond to simple information. Foundational; it affects performance across every other domain.
Holding and manipulating information in your mind. The capacity you rely on for reasoning, learning, and following complex instructions.
Planning, cognitive flexibility, and inhibitory control. These processes govern what you focus on, when you switch tasks, and when you stop.
Solving novel problems and detecting patterns without relying on prior knowledge. The closest measurable approximation of general reasoning ability.
Vocabulary depth, word relationships, and verbal reasoning. Crystallized knowledge: what you have learned and how flexibly you can apply it.
Core numerical intuition and quantity processing. This battery screens for dyscalculia, a specific learning difference affecting roughly 5 to 7% of the population.
Sustained focus, impulse control, and response consistency. These tests measure the core attention dimensions that differ in ADHD: not whether you can focus, but how your attention system regulates itself.
