Open instrument

Where should I start?

If you want the full explanation in a readable, non-technical format:

  • Concept — what FCE is and why baseline-relative matters
  • Scope & Limits — explicit non-goals and safeguards
  • How to Use — baseline, checks, and safe interpretation

What is FCE?

FCE (Functional Cognition & Execution) is a baseline-relative functional instrument. It measures how your performance today compares to your own normal range — not to population averages.

FCE measures function (speed, control, consistency). It does not measure diagnoses, substances, or “worthiness”.

Is this a medical test?

No.

FCE is not diagnostic and does not replace clinical evaluation. It is a functional measurement tool designed to support tracking and careful interpretation.

Does FCE measure the nervous system, hormones, or the endocannabinoid system?

No.

FCE does not measure biological systems, substances, or internal physiological states. It measures functional execution: how quickly, accurately, and consistently a person performs short tasks.

These outcomes can reflect the combined influence of many underlying systems, but FCE does not identify or attribute causes. It is a function-first instrument with human-led interpretation.

What tests are included?

  • Reaction Time — response speed and consistency
  • Go / No-Go — inhibition and control under time pressure
  • Divided Attention — Go / No-Go while counting brief visual flashes
  • Precision (Target Pointing) — motor accuracy and execution consistency

Divided Attention evaluates multiple signals. The overall status follows the worst deviation, so one strong signal cannot hide another weak signal.

How is this different from typical “reaction time” websites?

  • FCE builds a personal baseline instead of comparing you to others
  • Results are interpreted relative to your own normal
  • Multiple execution domains are measured (not one number)
  • Sessions are stored locally and shown transparently in History

What do “Baseline”, “Check”, and “Training” mean?

  • Baseline — builds your normal range (your reference)
  • Check — compares today to your baseline
  • Training — practice only (never updates baseline)

Mode is determined by the action button you choose.

Why do I need multiple baseline sessions?

Performance naturally varies day to day. A baseline is not one “best” score — it’s a stable reference built from multiple sessions.

Most people should collect 3–5 baseline sessions under normal conditions.

Can I compare results across devices?

Not reliably. Different devices and input methods (mouse vs touch) can change timing and error patterns.

For clean comparisons, build baseline and run checks on the same device and input method.

What do “Mean” and “SD” mean?

FCE summarizes performance using two simple statistics:

  • Mean — the average value (example: average reaction time across trials).
  • SD (Standard Deviation) — how variable the results are. Low SD = more stable/consistent. High SD = more spread and less stable performance.

In practice: two sessions can have the same mean but different SD. One can be steady, the other uneven.

What does “Not usable” mean?

Sometimes a session is marked as not usable. This is intentional.

  • It protects accuracy when data quality is too low
  • It prevents false certainty from incomplete or distorted input

Refusal is protection, not failure. Retesting is always allowed.

Do context fields change my result?

No. Context fields (sleep, stress, note) are saved as metadata only. They do not affect scoring or comparison.

Measurement first. Interpretation second.

Can FCE tell whether I'm impaired by a specific substance?

No.

FCE measures function — not cause. Different causes can produce similar functional deviation (sleep loss, stress, illness, medication, alcohol, cannabis, distraction).

Can using FCE help me understand myself better?

FCE does not interpret results or provide explanations about behavior, mood, or causes. It is a functional measurement instrument.

However, some users find that repeated use helps them notice changes in their own performance over time, such as stability, variability, or deviation from their normal range.

Any reflection that follows is user-led. FCE does not guide interpretation or suggest meaning.

Is FCE meant to be used for legal enforcement?

No.

FCE is not a legal verdict engine and should not be used for automatic enforcement or binding decisions.

If explored institutionally, safeguards must keep it voluntary, transparent, and contestable.

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.

Clearing site data in your browser will remove local history and baseline from that device.

Can I export my results?

Yes. Export is optional and user-initiated. The default instrument is designed around local storage and transparency-first history.

Any institutional data flow should be explicit and separate from the core instrument.
