The two reference ranges include the recorded total of 90 files with negative quarter gaps in 241 ds000030 files.

Across 241 stop-signal event files selected by a previously defined full-file screen from OpenNeuro ds000030, 90 files had at least one negative quarter time gap. Two permutation references that preserved each quarter’s GO and STOP response counts produced central 95% ranges of 88–110 and 88–111 files; both included 90. These descriptive references use 5,000 draws per file and this sample’s recorded responses. They do not replay the adaptive task, establish a valid biological null distribution, calibrate device timing, or support a general rule for individual participants. The analysis also reproduced all 1,862 recorded full-file, half, and quarter states and all 15,000 prior quarter reference comparisons in the stated scope.

  1. At least one quarter has a negative time gap in 90 of 241 selected ds000030 runs. sci:sha256:54eb55756416676f138947c2854f477b8f421c3172656d78fbb8419a12e0c5eb

    [Legacy relation: reproduces] New code agrees with all 1,862 full-file, half, and quarter states in 22,344 exact field comparisons. It also agrees with all 15,000 prior quarter reference rows for negative-file and missing-file totals across three samples. The added two references keep local response counts fixed. The prior half-reference simulation was not reproduced.

  2. usesThe four ds000030 metadata files do not give a timing error limit for the tested screen. sci:sha256:9338d279321ee3c19e8e3e63ebee1376fde7baba9c3ab256d9392adfe0fd6931

    Its package supplied all 266 event files, four metadata files, the source inventory, and the versioned retrieval manifest. Those inputs enabled the exact recorded and permutation calculations. This work does not resolve the timing calibration question.

  3. usesdoi:10.18112/openneuro.ds000030.v1.0.0

    The analysis uses the 266 scanner stop-signal event files recorded as ds000030 version 1.0.0; file-level source hashes and the fixed Git commit are preserved in the archive.

  4. supportsdoi:10.7554/eLife.46323

    The cited guide supplies the recommendation to include all responding GO and unsuccessful STOP trials, including choice errors and premature responses, and discusses scarce-data uncertainty for apparent mean-order violations.

  5. supportsdoi:10.1038/sdata.2016.110

    The cited data paper describes the dataset’s adaptive stop-signal ladders and 50 ms delay changes, which inform the stated limitation that these permutations do not replay the task.
