The adjusted recall slope interval included zero for consecutive pairs in nine-digit lists from 86 ds003838 v1.0.6 participants

We tested whether consecutive number pairs predicted correct serial recall in nine-digit lists. The source was OpenNeuro ds003838 version 1.0.6. We used 3,085 trials from 86 participants. The model compared lists within participant blocks. It adjusted for first digit, omitted digit, and trial position, with equal total weight per participant. The estimated slope was 0.07594 correct digits per extra pair. Its 95% interval was −0.01445 to 0.16883, from 20,000 participant bootstrap samples. The interval included zero and positive slopes. The result does not establish a causal effect, chunk use, or absence of an association. All planned secondary models are reported without correction for multiple comparisons. The package includes verified source files, a 9,276-row feature table, code, all bootstrap refits, figures, and reproduction instructions. Independent score and regression checks passed. A clean dependency installation reproduced the numerical results and all figure files.
