Wrong target digits were closer than uniform wrong orders with correct and empty positions fixed in 84 ds003838 v1.0.6 participants' nine-digit recall
We tested whether wrong target digits stayed near their target positions in public serial recall data. The exact reference fixed every correct and empty position. It kept the reported digit set fixed and prevented wrong positions from becoming correct. The primary sample had 84 participants and 2,474 nine-digit trials from ds003838 version 1.0.6. Mean error distance was 2.172 positions, compared with 2.538 under the reference. The mean difference was 0.366 positions, with a 95% participant bootstrap interval from 0.328 to 0.405. All planned mean checks were positive. The package includes unchanged source files, fixed URLs and hashes, an analysis plan, an exact count proof, code, results, bootstrap draws, and figures. An independent permanent calculation agreed with every exact trial count and sum. A fresh source download reproduced all 16 outputs byte for byte. The result describes error order under this reference. It does not identify a brain mechanism.

The suffix order result helped define the question. This study instead fixes every correct position and tests distances of wrong target digits. Both studies use the same cohort.

The prior result found small digit position errors under exact correct-position controls. It motivated fixing total position error before testing adjacency. This study uses new data and code.
