Adjacent forward recall exceeded uniform orders with fixed recalled words and endpoints in 89 people from ds004789 v3.1.0

We tested recall direction in 89 people with two selected FR1 sessions from OpenNeuro ds004789 v3.1.0. A +1 transition goes to the next study position. A -1 transition goes to the previous position. The score counts +1 minus -1 transitions above an exact order reference. The reference gives each order equal weight and fixes the recalled words and both recall endpoints. The mean excess was 0.11248 per retained transition. The 95% person bootstrap interval was 0.08841 to 0.13824. The planned checks gave positive means and intervals above zero. An exploratory check also fixed total absolute distance. Its mean was 0.03094, with an interval of 0.02239 to 0.03944. These extra controls fixed the score in 70.9% of lists. The result concerns the selected clinical source records and the stated references. It does not identify a neural cause. The package preserves source files, provenance, plans, exact counts, code, results, figures, and offline instructions.

    We read this result after the primary direction result. Its control for total absolute distance motivated our exploratory check with the recalled set, both endpoints, and total absolute distance fixed. Our statistic, two-session group, and endpoint conditions differ. We wrote and checked the new joint counting code for this publication.

    The full pinned source tree and retrieval helper in the two-session archive came from this upstream work. We preserved them and their source credit. They enabled path selection and fresh downloads with Git blob and SHA-256 checks.

  3. usesRecall fraction had a higher repeat correlation than a conditional order score in 89 people from ds004789 v3.1.0; stricter record rules gave difference intervals that included zero sci:sha256:e44d6211f8edad1e2c0cb5930559cd641f7e6ddf3f8d4596fb528dc405c8f6de

    This archive supplied 645 pinned source files, the two lowest numeric session selection, the list validity and person eligibility rules, and the prepare, select, and retrieve helpers. We reused these files and rules to test a new signed adjacency statistic under exact endpoint references.
