People can get better at staying with a particular attention task. Whether that becomes durable focus elsewhere is still uncertain—and a strong primary trial found no sustained-attention benefit.
This lesson teaches a simple sustained-attention routine. Move through one 60-token grid at a fixed pace of one token every four seconds, mark uppercase X only, notice when attention slips and return to the current token without racing. Score early and late accuracy separately, then repeat with the matched second grid after 3–7 days under the same conditions.
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 sustained attention in a declared context without inheriting broader claims.
What the current evidence supports
Sustained-attention performance can change on a practiced task, but current controlled evidence is conflicting and does not establish a broad or durable attention upgrade.
How to observe or measure it without overclaiming
Accuracy, errors, reaction-time variability, time-on-task decline and real-task completion must be reported separately; no one measure establishes general attention.
Myth
Unlock endless concentration
Metric
Predeclared vigilance accuracy and variability over time plus an independent real-task endpoint
Boundary
Practice on one attention test cannot establish durable focus everywhere.
Negative and limiting findings
A 100-person active-controlled post-TBI trial found no between-group effect on its preregistered primary sustained-attention outcome.
A large online study found practiced-task improvement without transfer to independent cognitive tests.
Claims this evidence cannot support
Build unlimited focus
Cure attention problems with meditation
VR repairs attention after brain injury
One vigilance score diagnoses attention
Evidence guide frame · non-prescriptive
A guide frame—not a training protocol.
Explain sustained attention as several task-bound measures whose evidence is conflicting, not as endless concentration.
What this frame may discuss
Evidence and measurement boundaries for sustained attention
Task specificity, access configurations and negative findings
Limits on transfer, efficacy and authority
Conceptual observations
Conceptually separate accuracy, missed targets, reaction-time variability and decline over time.
Treat context, accessibility and breaks as part of a task definition rather than personal weakness.
Reflection prompts
Which attention measure is actually being discussed?
What independent real-world outcome would be needed before claiming transfer?
What it cannot establish
Practice on one attention test cannot establish durable focus everywhere.
It cannot establish: Build unlimited focus.
It cannot establish: Cure attention problems with meditation.
It cannot establish: VR repairs attention after brain injury.
It cannot establish: One vigilance score diagnoses attention.
Accessibility alternatives
Text, audio or a static example may be chosen according to sensory and cognitive access.
Breaks, assistive technology and a no-response option are valid configuration features.
No timed vigilance task or self-test is requested.
Non-participation remains valid: Yes.
Stop and escalation boundaries
Stop if the frame becomes a timed test, endurance challenge, meditation dose, VR exposure or productivity target.
Stop if attention tracking increases distress, compulsive checking, fatigue or self-judgment.
New or concerning attention change, functional impairment or clinical questions require appropriate professional assessment.
Prohibited uses
Attention training dose, timed challenge, productivity schedule or clinical protocol.
ADHD, brain-injury or other diagnostic inference.
Streaks, scores, ranking or guaranteed transfer.

BaselineOpen the governed lesson and record its declared baseline before practising.
PractiseFollow the ordered lesson exactly; do not add dose, intensity or claims.
RetestUse the lesson's delayed retention and predeclared transfer checks as separate records.
Maintain or retireKeep only what remains useful inside the evidence and safety boundary.
Authority boundary: A governed step-by-step lesson may be completed independently inside its stated limits. 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.
No external confirmation is required for the current bounded explainer and non-prescriptive guide-frame permissions; any stronger efficacy, generalisation, protocol, promotion or independent-validation claim requires a new adjudication.
A separately governed practical lesson is available at /tutorials/pwr-097/. Its safe configuration, prerequisites, ordered practice, measurement, stopping, accessibility, retention, transfer and review rules remain controlling.
