Neurofeedback

Neurofeedback may teach control of a specified signal, but broad cognitive, emotional or clinical enhancement is not established.

Canonical Power learning unit · TLU-PWR-205

The learner completes every field in a two-study audit, using “not reported” where necessary, and writes separate conclusions for signal learning, the neurofeedback-versus-sham difference, functional benefit and no-feedback transfer.

Explanation is not permission.

This dossier explains the evidence and its limits. It is not a diagnosis, personal recommendation, assessment, clearance, performance promise or training programme. Actionable teaching appears only when the canonical Power record explicitly authorises it.

Complete bounded explanation

What this power means.

Capability to develop or express neurofeedback in a declared context without inheriting broader claims.

What the current evidence supports

Neurofeedback may teach control of a specified signal, but broad cognitive, emotional or clinical enhancement is not established.

How to observe or measure it without overclaiming

Prespecified signal change, sham difference, responder rate, no-feedback transfer and independent functional outcome. This measures the declared configured system and cannot by itself establish broad transfer, unaided ability, safety or legitimacy.

Myth

Training brainwaves upgrades the brain

Metric

Prespecified signal change, sham difference, responder rate, no-feedback transfer and independent functional outcome

Boundary

Report person, device/model/interface, task, assistance, failure state and comparator; the metric is not proof of unaided general capability.

Negative and limiting findings

Insomnia outcomes did not outperform sham despite target-signal learning, contradicting the master baseline's implication of uniformly strong coverage.
No cited evidence supports perfect, universal or consequence-free performance.

Claims this evidence cannot support

Training brainwaves upgrades the brain
The tool or robot's output proves an unaided, universal or permanent human superpower
A successful laboratory task proves independent real-world or clinical capability

How to learn this Power now.

Get readyKeep this as a paper-only exercise. Do not connect a sensor, choose a protocol or change treatment.
Learn the method10 concrete steps teach the permitted method from start to finish.
See right and wrong5 comparisons show correct or safer execution beside common wrong or riskier choices.
PractiseAfter at least seven days, start with blank tables and audit Study B again without looking at the first worksheet. Compare the two versions and correct omitted artefact, sham, prespecified-outcome or no-feedback fields. Use the method on a new paper only after every required field is either completed or explicitly marked not reported.
Check progressScore the sensor path, artefact handling, feedback rule, sham, blinding, prespecified outcomes, between-group result, uncertainty, adverse events, no-feedback test, delayed test and four-part verdict for each paper.

Authority boundary: Titan teaches a complete Power-specific research method because operational capability practice is not currently justified. The method is Power-specific; its actionability follows this treatment.

Citation roles are explicit. A source may support existence or trainability while simultaneously limiting transfer, certainty, generalisation or safety.

Current teaching and evidence boundary

The next gate remains visible.

External confirmation is required before higher-authority use because: a clinical, high-risk or regulated configuration; a supervision or non-attempt boundary; cultural, community-rights or affected-person authority; a restricted safety or legitimacy boundary.

A Power-specific tutorial is available at /tutorials/pwr-205/. It contains a plain-English method, 10 ordered steps, a worked example, right-versus-wrong comparisons, specific mistakes and corrections, practice, measurement, accessibility, stopping rules and evidence. Its research mode remains controlling.
