Adding test start coordinates reduces mean response prediction error in 41 YC1 first sessions under linear models
Test start coordinates helped predict spatial recall responses beyond the target coordinates. The test used 1,952 trials from 41 selected first sessions in OpenNeuro ds005522 version 1.0.0. Each test person was removed from model fitting. With linear models, mean squared prediction error fell from 252.46 to 221.27 arena units squared. The gain was 31.19 units squared, or 12.35%. The 95% interval from 10,000 refitted whole-person samples was 19.72 to 44.74 units squared. Seven specified checks also showed positive mean gains. Seventeen short first sessions were excluded. The result supports the tested response models in this cohort. It does not identify a memory or brain mechanism. The package preserves checked source extracts, code, all model results, source hashes, plans, and reproduction instructions. A full analysis repeat gave identical core result files.

- usesBoth intervals included zero for personal start calibration in 26 later YC1 sessions under fixed affine models
This publication supplied all 100 exact navigation extracts and the pinned source manifest. Its first-session result motivated our later-session test. We wrote new models and independent checks. We also retrieved one complete later-session raw file.
- usesPersonal target and start maps reduced second-session response prediction error in 18 YC1 people with a fixed 48-trial prior
We used all 100 navigation extracts, six metadata files, the fixed source tree, and source hashes from this package. New code selected trials and tested personal maps across sessions. No fitted model or selected trial table was reused.
