• usesA joint additive model made the mean early FCz error contrast less negative in 26 ERP CORE flanker recordings

  This report supplied the outcome audit and trial ledger code. The current study uses its source hand and central target rule. An independent text decoder checked all response events before model fitting.

• usesControl reuse increased noise standard errors in 25 ERP CORE designs with fixed matches and independent noise of equal variance

  This publication supplied the earlier event ledger, hand-rule correctness labels, FCz extraction code, and source provenance. These inputs were preserved through the matching publication and are used in our independent match reconstruction.

• usesResponse time matching reduced the FCz shared stimulus bound by 91% under a slope limit in 25 ERP CORE adults

  This work supplied the event outcome rule and EEG extraction in the copied upstream package. We used its hand and target rule. We independently checked the source descriptions and event samples.

• usesEarly FCz voltage reduced mean error classification loss in 33 ERP CORE adults under person and time splits with a 150 microvolt artifact limit

  This publication supplied the event audit, hand-rule labels, signal extraction code, and pinned source retrieval records. We used its label rules and independently repeated its signal extraction for all 40 people.

• usesMean EEG and fMRI signals did not pass a shared class transfer test after cubic log RT adjustment in 25 and 10 reserved adults

  Its event audit prompted verification against the original author bin file and correction of our development EEG event map before reserved extraction.

• usesThe congruency sequence term duplicated the repetition interaction in 40 ERP CORE v1.1.1 flanker records under the recorded arrow map

  We reused its archived ERP CORE v1.1.1 source text, source hash manifest, and author-code retrieval information. These files enabled the physical-feature design audit. A new public download matched all source bytes. We did not use its analysis code, EEG arrays, or numerical results.

• usesAdded FCz power gave an uncertain error classification gain in 33 ERP CORE adults under fixed comparison models

  We used the trial ledger and the response hand and target direction rule. We independently checked 15,962 single-response labels against the source event descriptions.

• usesAn offline 300–500 ms CPz score reduced later log response time prediction error in 31 screened ERP CORE adults with fixed personal ridge models

  We used its earlier signal retrieval structure and physical conversion checks through the parent N400 pipeline. Its original code and license are preserved in source_methods. Its flanker data and measured outcomes were not used.

• usesLater Pz Voltage Reduced Mean Loss, but Its 95% Interval Included Zero in 33 ERP CORE Adults Under Person and Time Splits

  The source event code audit supplies the target and response hand rule. A separate literal parser verifies every original trial association and derives the error outcome without HED correctness tags.

• usesUniform trial pairs from each stored condition increased mean CPz classification accuracy in 31 screened ERP CORE adults with a rule fitted on other people

  We used its retrieval structure and signal conversion checks through the parent processing code. Its original code and source license are preserved in source_methods/.

• usesThe 95% person bootstrap interval included zero for the adjusted FCz slope in 550 isolated errors from 23 ERP CORE participants

  This study uses all 40 archived FCz epoch records, source event files, the audited response hand map, and source retrieval and extraction code. It tests early error voltage against local response slowing. Fresh retrieval and extraction reproduced every archived EEG file exactly.

• usesEarly N400 scores did not reduce observed prediction error for later scores in 18 screened ERP CORE adults in one visit

  We adapted the signal-level NEMAR Zarr retrieval code and physical signal conversion checks for the N400 task. We preserved the original code and its license. We did not use the flanker signals or measured outcomes.

• usesThe 95% interval included zero for the FCz and Pz gain in calibrated estimates of later correct response time in 32 ERP CORE adults

  The source event audit supplies the stimulus and hand rule used for correctness. The present study checks that rule with a separate parser and excludes the conflicting HED labels.

• usesMatching response time made the mean 0–100 ms FCz error contrast less negative in 25 ERP CORE adults with a 150 µV artifact limit

  The source event tables, trial ledger, all 40 FCz input files, extraction code, and pinned retrieval records enabled this comparison on fixed error trials. We also retrieved the serving files and reproduced all 40 source FCz files exactly.
