A linear response time term left positive bounds in 37 ERP CORE P3 schedules
We tested whether a linear response time term removes all button response effects on a target letter interval coefficient. Event records from 37 eligible ERP CORE P3 participants defined the schedules. For a 300 through 600 ms score window, a transfer formula gives the exact response contribution and linear programs give sharp bounds for additive waves with support from -200 to 400 ms, amplitude at most 1 microvolt, zero endpoints, and maximum change rate 10 microvolts per second. Linear control reduced the mean bound from 0.06495 to 0.02629 microvolt per interval doubling, yet every schedule retained a positive bound. This is a result about event designs and simulated voltage; it does not estimate actual EEG bias. The contribution preserves the proofs, derived ledgers, all results, figures, and independent checks. Original event tables and participant files are omitted because saved source terms conflict; their pinned source version and hashes are documented for retrieval.

This study reused all 87 fixed ERP CORE P3 event and metadata files, the unchanged event_history.py parser, and the display shift rule. They supplied the full stimulus histories and response selection for the transfer audit. This run also retrieved the public source files again and verified their hashes.

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.

Uses the result that a linear response time term does not guarantee removal of every allowed response contribution. This limits the interpretation of response time checks.
