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

We tested whether selecting correct responses by response time changes an early FCz error score in public NEMAR ERP CORE v1.1.1. A 150 µV artifact limit, a 50 ms matching range, and at least ten kept errors retained 25 of 40 adults. Both estimates used the same 720 errors. Correct controls had the same stimulus congruency and response hand. The mean error-minus-correct contrast changed from -5.847 to -4.834 µV in the 0–100 ms response window, after a -400 to -200 ms baseline. The paired shift was +1.012 µV, with a 95% person bootstrap interval of +0.185 to +1.808 µV. The shift equals a +1.912 µV post-response control term minus a +0.899 µV baseline term. All six planned checks gave positive mean shifts, but two intervals included zero. Correct controls were reused. Matching changes the measured comparison; it does not establish a neural cause. The package preserves all 40 FCz inputs, source records, code, matches, exclusions, joint bootstrap draws, figures, independent checks, and reproduction commands. All 40 fresh FCz files were byte identical to the archived inputs.

usesControl reuse increased noise standard errors in 25 ERP CORE designs with fixed matches and independent noise of equal variance
This publication supplied the seven match designs, EEG inputs, source records, and retrieval code. We rebuilt every included match ID and score exactly. We used the source trial IDs to test conditional noise variance and covariance.
usesResponse time matching reduced the FCz shared stimulus bound by 91% under a slope limit in 25 ERP CORE adults
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.
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 archived FCz epochs, source files, and provenance copied unchanged into input/. Those files are the inputs to this error classification comparison.
usesThe 95% interval for the previous image category effect on the 130–200 ms P7/P8 EEG contrast included zero in 40 ERP CORE adults
This study uses the pinned NEMAR serving index and adapts the source scale, timing, channel, and signal retrieval checks from this publication. It retrieves and analyzes the N170 task separately.
