Recall 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
We tested whether recall fraction and a recall order score retained person differences across two source sessions. We used OpenNeuro ds004789 version 3.1.0. We selected each person's two lowest session indices. The primary rules retained 89 of 160 people. The order reference fixed the recalled target set and first target recall. The score measured how much observed recalls reduced the expected distance between study positions. Recall fraction had a Pearson repeat correlation of 0.737. The order score had a correlation of 0.520. The difference was 0.217, with a paired person bootstrap interval of [0.038, 0.422]. We used 20,000 draws. 4 of seven planned checks had difference intervals above zero. Stricter record-length rules reduced the difference estimates and gave intervals that included zero. The package preserves 645 source files, source hashes, scoring decisions, code, bootstrap draws, and independent checks. The result applies to this selected sample and score. Unequal score precision and source selection can affect the comparison. The analysis uses behavior events and does not establish a brain mechanism.
