Excess non-target color alignment increased by 2.09 percentage points from two to six items in 117 ds008037 v1.0.1 adults under fixed angle rules and a control based on other trials
We tested 33,299 color reports from 117 adults in OpenNeuro ds008037 version 1.0.1. A report counted as aligned when its target error was above 30 degrees and it was within 15 degrees of a non-target color. We compared each report error with all other trial arrays in the same person, block and load. Excess alignment is the actual rate minus this control rate. From two to six items, actual alignment increased by 27.54 percentage points and the control increased by 25.46 points. Excess alignment increased by 2.09 points, with a 95% person bootstrap interval of 1.32 to 2.84 points. All five planned checks had positive intervals. The control requires exchangeable target-relative arrays under its null. The bootstrap keeps trials fixed and assumes independent people. The score does not identify a swap probability or a brain mechanism. The package preserves all selected source files, fixed source hashes, code, control matrices, bootstrap draws, figures and instructions. A separate scalar implementation confirmed all scores and bootstrap draws. Fresh source retrieval and a second analysis also passed.

5- usesWith circular error scores, mean error had a higher Pearson correlation across color and orientation tasks than load cost in 115 selected ds008037 v1.0.1 adults sci:sha256:e8a3c7eca943ddf09e69ed38dffea5bc790ab7bdb6f33273e4f847dbd4286ba0
We used its unchanged color task tables, dictionaries, dataset files and pinned source provenance for our initial local copy. We used no prior analysis code or person scores. We then independently retrieved all 240 selected files from the fixed public commit and confirmed their hashes.

- usesA fixed ridge test did not show lower sine error loss from previous report angles in 59 ds008037 v1.0.1 adults
This package supplied unchanged ds008037 v1.0.1 color tables and source hashes. Fresh retrieval matched those hashes. The present work adds EEG event order checks and a new previous-report prediction test.
- supportsOther trial colors increased mean report log density across loads 2, 4, and 6 in 59 ds008037 v1.0.1 test adults under fixed fits with two kernel widths
The present report prediction gain agrees with this publication's evidence for trial-specific non-target color information under a different score. We read that report after our fits and did not change the analysis. Both reports use the same cohort. This is not independent replication.
- usesNon-target color terms reduced mean report log loss in 57 ds008037 v1.0.1 test adults with fixed circular mixtures
Its same-cohort alignment result helped define the question. Its use of other trial arrays informed the control. This study tests prediction with separate training and test people.
