Cognitive Tests & Executive Function Assessments
Interactive cognitive assessments that measure attention, inhibition, reaction time, and other executive function skills. These computer-based tests provide objective measurements of cognitive performance.
What are Cognitive Tests?
Cognitive tests are computer-based assessments that measure specific brain functions like attention, response inhibition, and reaction time. Unlike self-report questionnaires, these tests provide objective, performance-based measurements of executive function skills that are often affected in ADHD.
These tests can complement questionnaire-based screeners by providing additional data about cognitive performance patterns that may indicate attention or impulse control difficulties.

5-7 minImpulse control task measuring inhibition and reaction time
The Go/No-Go task is a computer-based cognitive test that measures response inhibition, impulse control, and sustained attention. You'll see green (go) and red (no-go) stimuli - press the spacebar only when green appears. Approximately 80% are go trials and 20% are no-go trials.
CPT-Lite
5-7 minSustained attention task measuring focus and reaction time variability
The CPT-Lite is a simplified version of the Continuous Performance Test, designed to measure sustained attention, vigilance, and reaction time. Letters will appear on screen - press the spacebar only when you see the letter 'X'.
