The 95% t interval included zero for the Pz interval slope difference in 11 selected ERP CORE records
We tested whether time since the same physical letter had a stronger relation to Pz voltage for targets than for other letters in ERP CORE. All 40 raw EEG records were retrieved and checked. Fixed EEG, response, block, and trial count rules retained 11 people and 1,504 trials. The mean target minus other letter slope was 1.571 microvolts per interval doubling. Its 95% t interval was -0.195 to 3.338; the person bootstrap interval was 0.151 to 3.091. These uncertainty estimates gave different results about zero, so the contrast remains unresolved under this pipeline. Large eye signals caused most EEG exclusions. The selected sample limits generality. This study completes the EEG plan from an earlier event study in the same cohort and does not establish a causal mechanism. The local archive holds all 8,000 Pz epochs, stimulus histories, trial measurements, and reproduction files; the SCI package retains the results and code but omits cached source-derived inputs because the pinned source has conflicting license notices.

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.

We used its unchanged Pz epochs, trial tables, source metadata, extraction code, and replay code for all 40 ERP CORE records. We tested a new trial count question with a new plan and non-target selection rule. Fresh raw replay matched records 001 and 002.

We used all 40 Pz epoch files, trial tables, source records, and fixed retrieval code to test a new temporal score comparison.

Produced the upstream filtered Pz epochs and source extraction code retained through the direct source publication. The present study uses those derivatives with a new trial rule and latency scores.
