Personal wait history calibration increased run 2 mean squared response time error in 75 ds003690 adults on the simple task at penalty 8
We tested whether personal wait history calibration improved response time forecasts in OpenNeuro ds003690 version 1.0.0. The simple task supplied two runs from 75 adults. Both rules used the same personal run 1 mean speed. The shared rule used run 1 data from other people in the same recorded age group. At ridge penalty 8, two personal wait history coefficients increased balanced run 2 mean squared error by 226.69 ms², or 3.76%. The 95% refitted whole-person bootstrap interval for the increase was 76.69 to 368.41 ms². All nine planned checks had negative gain estimates. Stronger shrinkage left a small benefit possible. The result applies to clean cue pairs, these short runs, and fixed model rules. It does not exclude stable personal timing traits. The package preserves 905 source files, code, forecasts, coefficients, all random draws, hashes, and reproduction instructions. Independent checks passed. Fresh-source and clean-environment replays matched all outputs byte for byte.

This earlier report supplied the group response contrast for current and previous waits in ds003690. We read it before the local plan. It motivated a separate-run forecast test. Our models, clean-response selection, and target differ. The new result does not reproduce or challenge its group contrast.

The inherited source manifest identifies this report as an earlier source of the go/no-go event files. We retained those exact files and retrieved them again. They support the planned go/no-go forecast check in all 75 adults.

This report supplied all 905 active-task source and metadata files, the inspected event extractor, the source manifest, and retrieval code. We preserved the code unchanged and checked its parent hashes. We retrieved all source bytes again. The new analysis tests personal calibration in a separate run, beyond the same personal speed offset.
