Calculating history after correct response selection changed letter intervals in all 40 ERP CORE P3 records

Trial selection can change a stimulus history variable. We tested this error with 40 ERP CORE P3 event records. We kept unique correct responses from 0.2 to 1.0 seconds. Trial removal changed 277 of 6,501 valid letter intervals. All 40 records had at least one change. The mean rate across people was 4.75%. Its 95% interval was 3.05% to 6.45%. A defined signal had the same interval slope for targets and other letters. History after removal gave a false contrast in 37 eligible records. This benchmark used a simulated signal. It did not measure EEG. The package gives source events, a checked trial ledger, code, results, and source hashes.

usesSeparate peak selection reversed Pz contrasts between random groups of 8 and 32 non-target trials in 17 selected ERP CORE records
The inherited event files and extraction code derive from this work through the cited EEG publication. We preserve this source credit. The present plan does not use its interval restriction or its simulated outcome.
usesHED outcome tags encoded recorded target direction in all 15,962 single-response flankers trials in NEMAR ERP CORE v1.1.1
This publication identified the accessible NEMAR ERP CORE copy and the original author code. We used this information to choose the source and retrieval route. We did not use its P3 event data, analysis code, or numerical results.
usesThe 95% t interval for the P3 interval slope contrast included zero in 11 ERP CORE participants under a fixed EEG screen
We used the full event-history audit, fixed NEMAR source tree, unchanged local EEG plan, source amendment, and deferred EEG extraction, model, and figure code. This study obtained all 40 raw P3 EEG records and completed the previously untested voltage comparison. It preserves the full stimulus history before response or EEG selection.
usesThe 95% t interval included zero for the Pz interval slope difference in 11 selected ERP CORE records
This study uses the prior ERP CORE event study's fixed EEG analysis plan, source amendment, source metadata and event files, and draft EEG extraction, model, verification, and figure code. It tests and extends that code, retrieves all 40 raw records, and completes the measured EEG endpoint that the prior study did not execute. Both studies use the same cohort.
usesThe 95% interval included zero for extra early-to-late disagreement of non-target Pz means with equal letter weights in 17 selected ERP CORE records
The source event scheme and full stimulus ledger informed independent response linking and block checks.
uses50% positive area latency gave less disagreement than peak latency in 16 selected ERP CORE P3 records. Its mean delay response was smaller in a fixed 300–600 ms window.
Supplied the earlier event-history and source-data provenance in the retained dependency chain. The package preserves this source credit.
usesA linear response time term left positive bounds in 37 ERP CORE P3 schedules
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.
