Research Program / Claims / afterimage-9
When you cease actively constructing an object, its pattern begins to fade but remains inactive, with weak vibrations that can still be perceived.
当你停止对一个物体的主动建构时，该物体的模式开始消退但仍保持不活跃，此时仍存在可被感知的微弱振动。

This program treats the Seth Material as a source of hypotheses, not as doctrine to be validated. Lead dossiers are AI-compiled from the corpus with a book-and-session citation after every statement; literature reviews are AI web-search summaries whose references were all DOI-verified against Crossref; the agenda draft is an AI synthesis. None of it is Seth's original text, and none of it represents scientific consensus. English fields are machine-translated; the Chinese text is authoritative.

Adjudicating experiment
First distinguish internal perceptual traces from external residual fields. Approximately 120 observers would randomly perform active viewing, attention-shifting, and imagined cessation conditions while the physical stimulus remains unchanged, with an additional condition in which the stimulus is actually removed. Each observer would complete 100–200 trials, recording afterimage matching, eye movements, and EEG over 12–18 months. The external-field version would add blinded observers who had not seen the original stimulus, optical shielding, and detectors selected for the specified frequency band, accumulating at least 10^4 randomized events. The key criterion is whether independent observers and instruments can extract information about the original object, rather than merely whether the original observer reports decay.
Suggested paper title
Dissociating Perceptual Persistence from External Residual Signals after Stimulus Withdrawal
What it would overturn
If an externally readable signal appeared contingent on the observer ceasing construction, this would revise the usual assumption that “attentional states alter perception but do not produce an independent information carrier at the object's location.”

Specificity of Seth's formulation
The original text defines neither the operation of active construction, the carrier of the vibrations, their frequency, nor the perceptual threshold, and therefore cannot distinguish memory, adaptation, and external residual mechanisms.
Note
Nonexponential decay can arise from multiple adaptation time constants, eye movements, or measurement thresholds; it need not involve oscillation and cannot establish “weak vibrations.” If ultraweak photon emission is measured, ordinary afterglow and biological background must also be ruled out.
