Ten-second motion traces have a greater mean correlation within films than across films in 68 adults from nine NNDb films
We tested motion change in 68 adults from nine films in OpenNeuro ds002837 version 2.0.0. We used 29 minutes from the first continuous scan and nominal one-second timing. Ten-second motion traces had a mean Fisher z score of 0.03273 within films and 0.00360 across films. The difference was 0.02913, with a participant bootstrap 95% interval from 0.00496 to 0.05569. The time shift probability was 0.0001 under a stated circular shift model. The evidence was weaker at one and thirty seconds. The package preserves 175 source files, code, results, resamples, figures, and reproduction instructions. Separate calculations and fresh downloads confirmed the results. The evidence concerns motion estimates in this selected sample. It does not establish a film cause or a brain signal effect.

- usesMean film recall from 0.2 mm motion masks with 10 s bins was within reference ranges in 68 NNDb adults
We used its unchanged 175 source files, fixed retrieval manifest, timing documents, and 68-person selection rule. We built new binary mask prediction features and checked all source bytes by fresh retrieval.
- usesTen-second motion traces gave 32.45% balanced film accuracy in 68 NNDb adults from nine films when each test person was excluded from training
This study uses the fixed motion source subset, source manifest, timing documentation, and retrieval helper from the earlier correlation study. That result informed the question and primary ten-second bins. The present outcome is film prediction for a person excluded from all training templates in the same cohort.
- usesThe 95% person bootstrap interval included zero for within-film excess shared scan removal at a 0.2 mm FD limit in 68 NNDb adults from nine films over 29 minutes with a 50 mm radius
We used its 175 fixed source files, hashes, locked retrieval code, selection rules, and nominal time grid. This study tests binary scan mask covariance in the same people. It supplies a new endpoint, not an independent sample replication.
- usesShared time for four people was within the independent circular shift reference range in 68 NNDb adults at a 0.2 mm FD limit
This study uses the preserved 175-file NNDb source subset, fixed source manifest, and processing provenance. The prior motion timing result set the direction of the primary hypothesis. The new outcome is common retained time, rather than correlation between motion traces.
- usesThe 95% participant interval included zero for a same-film overlap increase under a 0.2 mm motion rule in 68 NNDb adults
We used its 175 unchanged NNDb source files and locked source manifest. We rebuilt its 68-person sample from those files. Its known continuous motion result informed the new question. We calculated new binary masks, local rate references, pair overlap scores, and resampling results.
