The mean target-gap slope for 300–600 ms Pz EEG voltage was uncertain in 13 participants from ds003061 version 1.1.2
We tested the relation between target gaps and Pz EEG voltage from 300 to 600 ms in OpenNeuro ds003061, version 1.1.2. The test used 4,156 targets from 13 participants. After baseline subtraction, the mean slope was 0.633 microvolts per doubling of the gap. The 95% participant bootstrap interval was -0.090 to 1.307 microvolts. The exact two-sided sign-flip p value was 0.1160. Nine participant slopes were positive. The group relation remained uncertain. The stricter voltage screen, fitted-baseline model, and added pause check also gave uncertain estimates. Response-only checks had larger estimates and are reported as secondary results. The package preserves 4,247 Pz epochs, all target histories, source event tables, raw-file hashes, code, and reproduction instructions. Independent measurement and coefficient checks passed. A second offline analysis gave identical numeric output hashes. This observational result does not establish a causal brain mechanism.
