What is FCE?

FCE is a baseline-relative functional instrument. It compares current short-task performance to your own usual range rather than to population averages.

Is FCE a medical test?

No.

FCE is not diagnostic and does not replace clinical evaluation.

Does FCE detect substances or internal biological states?

No.

FCE does not detect substances, hormones, neurological states, or internal physiological systems directly. It measures observable task execution only.

What tasks are included?

  • Reaction Time — response speed and consistency
  • Go / No-Go — inhibition and response control
  • Divided Attention — dual-demand execution
  • Precision — motor accuracy and consistency

What do Baseline, Check, and Training mean?

  • Baseline builds your personal reference range.
  • Check compares today to that reference.
  • Training is practice only and does not update baseline.

Why do I need more than one baseline session?

Because performance varies naturally. A baseline should reflect your usual range, not a single score.

Most users should collect 3–5 usable baseline sessions.

Can I compare across different devices?

Not reliably. Device and input differences can affect timing and error patterns.

Use the same device and input method for baseline and checks whenever possible.

What do Mean and SD mean?

  • Mean = average value
  • SD (standard deviation) = how variable the results are

Lower SD usually means more stable performance. Higher SD usually means more spread or inconsistency.

What does Not usable mean?

It means the session was not reliable enough for comparison.

  • too little valid data
  • too much noise
  • too much execution failure

Not usable is protection, not punishment.

Do context fields change scoring?

No.

Context fields such as sleep, stress, and notes are stored as metadata only.

Can FCE tell why performance changed?

No.

Different causes can produce similar deviations. FCE shows change in function. It does not identify the cause of that change.

Can FCE be used for automatic legal or institutional decisions?

No.

FCE is not a legal verdict engine and should not be treated as an automated decision system.

Where is my data stored?

Locally in your browser on this device. FCE does not require an account and does not upload data by default.

Can I export my results?

Yes. Export is optional and user-initiated.

Do FCE results correspond directly to real-world performance?

No.

FCE measures short-task execution signals under controlled conditions. How these signals relate to real-world performance is not yet formally validated.
