The Pz target interval slope had a 95% interval that included zero in 10 eligible adults in ds003061 version 1.1.2

We tested whether time since the previous physical target predicts mean Pz voltage after a correct auditory target. We used all 39 EEG files from OpenNeuro ds003061 version 1.1.2. The rules were fixed before EEG measurement. The primary model used 2,130 trials from 10 eligible adults. The mean slope was 0.686 microvolts per interval doubling. The 95% Student t interval was -0.407 to 1.780. The exact sign-flip probability was 0.173828. This result does not establish a positive target interval effect. Baseline subtraction changed the mean slope from -0.550 to 0.686 on the same trials. These values do not identify the cause of the change. The package preserves code, source metadata, trial records, 28,425 Pz epochs, results, checks, and an exact raw-file retrieval recipe. All source files passed size and hash checks. A second offline analysis reproduced all eleven numerical result files exactly. The evidence applies to this sample, task, reference, filter, and trial selection. It describes association under the fitted model.
