With digit counts, correct positions, first error digits, and distance counts fixed, displaced pairs exceeded the uniform order mean in 86 ds003838 participants' nine-digit recall
We tested displaced adjacent digit pairs in OpenNeuro ds003838 version 1.0.6. The main analysis used 3,085 nine-digit trials from 86 participants. A pair counted only when both response positions were wrong. Exact uniform orders fixed scored digit counts, response length, correct positions, first error digits, and absolute distance counts. Participant means had equal weight. The mean excess was 0.023736 pairs per trial. Its 95% participant bootstrap interval was 0.015642 to 0.032190. The interval assumes independent participants suitable for resampling. Letting distance counts vary gave 0.269977 excess pairs per trial. Fixing them reduced the excess by 91.2%. Only 288 main trials had variable pair counts under the strict rule. All planned checks had positive means. Secondary checks are descriptive. The package preserves source inputs, exact distributions, code, a counting proof, and reproduction commands. Independent complete-permutation checks passed. Fresh source downloads reproduced all seven computation files byte for byte. The result describes a chosen order reference. It does not identify a brain mechanism or stored memory chunks.
