Response time matching reduced the FCz shared stimulus bound by 91% under a slope limit in 25 ERP CORE adults
Nearest response time matching reduced a shared stimulus waveform bound in 25 selected ERP CORE adults. Matches used the same physical stimulus and 713 errors. The model assumes one shared processed waveform for errors and correct trials within each person and stimulus. Under a positive slope limit L, the mean FCz bound fell from 0.175060 L to 0.016532 L microvolts. That is a 90.56 percent reduction. The paired norm reduction was 0.158528 seconds. Its 95 percent person bootstrap interval was 0.140454 to 0.176882 seconds. The voltage contrast remained negative. The interval for its change included zero. Code gives exact rational bounds and waveforms that reach them. A separate curvature class and all five sensitivity checks are preserved. Fresh retrieval and extraction reproduced all 40 source EEG files byte for byte. All 37 numerical outputs were reproduced. The bound concerns the trial's own stimulus under explicit assumptions. It does not identify a pure neural error signal.

This work supplied the preserved FCz records, source files, extraction code, and replay script. We used them for all six settings. Its earlier response time result gave the starting question.

This work supplied context for bounds on event waveform contributions. We used its idea of bounds defined by event design. We applied new exact derivative norms to a shared own-stimulus model and measured FCz scores.

This report supplied the pinned 250 Hz signal retrieval recipe and preserved trial extraction. We checked its epochs and artifact scores against a source rebuild. Its response time matching result motivated a direct stimulus and response model comparison. The current study uses the same cohort.
