In 22 people from ds004117, an additive model at fixed full sequence position gives a common slope of 9.5 ms per later remembered letter, with a 95% interval that includes zero

The adjusted response time changed by 9.5 ms per later remembered letter at fixed full sequence position. The 95% person bootstrap interval was -18.5 to 37.2 ms. The study used 1,072 correct target trials from 22 people in OpenNeuro ds004117 version 1.0.1. The additive model assumes one common linear memory position slope and one shared full sequence curve. The interval leaves the direction uncertain. It does not establish that memory position has no effect. A planned secondary model gave different slope estimates by memory load. Those estimates depend on the shared sequence curve. The package adds a checked table of all 1,162 complete target trials with source row links. It preserves all 176 source text files, exact URLs and hashes, the local plan, code, every planned fit, and all person samples. An independent parser and full weighted fits agreed. A fresh source download gave identical bytes for all 71 numerical outputs. The result concerns recorded behavior in one task. It does not identify a brain mechanism.
