Early flanker sequence scores gave no clear gain over peer means under linear prediction in 270 selected ds007139 v1.0.0 people
We tested whether an early flanker sequence score improved prediction of the same score in the later task half. We used 288 public event files from OpenNeuro ds007139 version 1.0.0. The main rules selected 270 people and 80,120 valid stimulus pairs. The score gave equal weight to response repetitions and changes. For each test person, a linear model and a peer mean used only other people for training. The personal model had mean squared error of 623.31 ms squared, compared with 619.63 for the peer mean. The gain was -3.68 ms squared. Its 95% person bootstrap interval was -23.85 to 16.64. The one-sided permutation p value was 0.589. The early-late score correlation was 0.079. Mean response time gave a correlation of 0.843 and a clear supporting prediction gain. All six planned sensitivity intervals for the sequence-score gain included zero. A new public download matched all 582 input hashes. A full repeat matched all 37 analysis outputs byte for byte. The package preserves source data, code, person scores, predictions, draws, and check records. This selected-cohort, one-session test gave no clear gain for the tested linear model. It does not prove zero gain or test an EEG signal.

We used its fixed source bytes and event rules. Its group sequence result motivated a new early-to-late prediction test. We wrote new code and used no prior person scores or bootstrap draws. A new public download matched all source hashes.

Its comparison of task-half correlations in the same public cohort motivated the mean response time control. We computed new scores from source events and used no prior error-slowing scores.

Its personal and peer score comparison motivated the peer prediction reference. Its rule that removes every sampled copy of a test identity guided our bootstrap training. We test a different cohort and score with a fitted linear model.

Its cross-version score comparison provides related measurement context from a different cohort. This study tests the added prediction value of an early score over a peer mean. We did not use its source data, person scores, or results as inputs.
