Penfield Cognitive / Research preview
Measure your
cognition.
A free adaptive cognitive assessment estimating general cognitive ability and domain performance with a stated likely range, not a single claimed score.
Early versions are a research preview: accuracy improves through norming, psychometric calibration and external validation. This is not a clinical diagnosis and not a definitive IQ figure.
Choose a mode. This preview runs four sample items so you can see how the assessment feels. It is not scored and produces no estimate.
Nothing is sent or stored by this site. The calibrated assessment is in development. This preview demonstrates format, not scoring.
Responses stay in your browser. Nothing is sent or stored. Contributing de-identified results to research is optional and separate from taking the assessment.
