Norms for a Voice-Based Digital Cognitive Test Across Ages

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study uses a secure, web-based platform to collect a one-time, non-invasive cognitive assessment from healthy adults. Researchers will generate age-, sex-, and education-adjusted reference values to standardize the digital test across the lifespan. After electronic consent and a screening questionnaire, eligible participants will complete the standardized cognitive assessment remotely on a computer, tablet, or smartphone. The study does not involve any therapeutic intervention or changes to standard medical care. Exclusion criteria include known cognitive impairment, neurological illness, or psychiatric conditions that could affect test performance.

Why it matters

Who can join: the full rules

Inclusion Criteria:

* Adults aged 18 to 100 years at the time of enrollment.
* Able to read, speak, and understand English sufficiently to complete all study procedures.
* Able and willing to provide informed consent.
* Adequate hearing, speech, and vision (with corrective devices if needed) to complete computerized voice-recognition cognitive testing.
* Able to independently complete the digital cognitive assessment using a computer, tablet, or smartphone with internet access (or at a supervised study site if applicable).

Exclusion Criteria:

* Known Cognitive Impairment Self-reported or previously diagnosed cognitive impairment, memory disorder, mild cognitive impairment, or dementia.
* Neurological Disease or Brain Injury History of a neurological condition or brain injury that, in the opinion of the investigator, may adversely affect cognitive performance.
* Psychiatric Illness Current or untreated psychiatric illness that may significantly influence cognitive testing performance.
* Substance Use or Cognitive-Impacting Medications Current use of substances or medications known to significantly impair cognition or recent substance use that could affect test validity.
* Sensory or Communication Limitations Inadequate English proficiency or speech, hearing, or visual impairments that would prevent valid completion of the digital cognitive assessment.
* Functional or Medical Conditions Affecting Cognition Medical conditions or functional impairments that, in the opinion of the investigator, may interfere with accurate assessment of normal cognitive performance.
* Investigator Discretion Any other condition or circumstance that, in the judgment of the Principal Investigator, would compromise participant safety, study compliance, or the validity of the normative dataset.
