Mean film recall from 0.2 mm motion masks with 10 s bins was within reference ranges in 68 NNDb adults

We tested film prediction from proposed motion removal masks in 68 NNDb adults from nine films. The source was OpenNeuro ds002837 version 2.0.0. The primary mask marked FD above 0.2 mm. The fixed rule used 10 s bins and excluded each test person from training. Mean film recall was 19.35%; 14 of 68 predictions were correct. The score was inside central 95% ranges from 9,999 label shuffles and 9,999 feature timing shifts. The one-sided values were 0.0615 and 0.0504. These references need exchangeable labels or circular time phases. Film assignment considered previous viewing and genre. The approximate person bootstrap interval was 6.48% to 36.06%. Its coverage was not verified. Six planned supporting rules gave mean recall from 8.98% to 29.91%. The earlier continuous motion point score of 32.45% was reproduced in the same people. The primary result does not establish that masks lack film information. No brain signal effect was tested. The package preserves source bytes, fixed URLs and hashes, code, features, predictions, all draws, and independent checks. A fresh retrieval reproduced all 20 numerical result files byte for byte. Repeat instructions and exportable figures are included.

    [Legacy relation: reproduces] We reproduced its continuous motion point score: 32.45% mean film recall and 24 correct labels. We used the same 68 people and fixed continuous rule. Its template prediction method informed the new binary mask test. This is a calculation repeat, not an independent cohort replication.

  2. usesShared time for four people was within the independent circular shift reference range in 68 NNDb adults at a 0.2 mm FD limit sci:sha256:bef7daaaee4c58619ac53df131db28ca1c21cba01dde035daf4e456bd84be00b

    Its test of shared retained time motivated the separate question about film prediction from mask timing. We used its 0.2 mm mask context and shared source scope when we fixed the plan.

  3. usesThe 95% participant interval included zero for a same-film overlap increase under a 0.2 mm motion rule in 68 NNDb adults sci:sha256:f0a00fb1e660761ee178c22fc074798b633956e60f5ed3380c33f7bd85abd913

    We used its summary of locally adjusted mask overlap to describe related evidence and time-shift limits. Its people are shared with this study. We read it during final review and made no analysis change.

  4. usesTen-second motion traces have a greater mean correlation within films than across films in 68 adults from nine NNDb films sci:sha256:5dc3aaf5fe610677e63a7a3800139d134124ee0a5b600b8a23b818f44597adcf

    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.

  5. 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 sci:sha256:3374d30384ba30a3e7a16d1de065680117fabcd895969d76d8ecadbe729b6f1a

    We used its summary of uncertain within-film excess mask overlap in the final evidence review. It shares the source people but measures a different endpoint. We added context and made no analysis change.

    This study supplies the reported prior evidence of shared motion timing during film viewing that motivated testing mask timing as a feature.
