The Choose A minus Avoid B score had opposite mean signs for C/E and D/F in 77 ds004532 Study 1 participants
We tested the Choose A minus Avoid B transfer score in OpenNeuro ds004532 version 1.2.0. The primary sample had 77 Study 1 participants with at least four valid responses in every required cell. C/E and D/F used the same participants and endpoints. The mean score was -33.4 percentage points with C/E and +16.7 points with D/F. The mean within-person gap was -50.1 points. Its 95% participant bootstrap interval was -62.1 to -38.0 points. The group scores had opposite nonzero signs in 39 of 77 participants. All six planned checks kept a negative mean gap. Under a fixed, strictly increasing, symmetric choice rule, the expected score decreases with comparison value and is zero at the endpoint midpoint. This proof does not require separate learning rates. The result does not identify a neural cause or establish the choice model in these participants. The package preserves source files, exact source hashes, code, bootstrap draws, figures, and reproduction instructions. Independent calculations passed. A fresh source download and full rerun gave identical result files.

- usesChoice and block adjustment reduced the mean linear feedback contrast by 9.05 percentage points in 78 ds004532 v1.2.0 Study 1 participants
This publication supplied 147 preserved ds004532 v1.2.0 source files and their fixed-commit retrieval manifest. We used its event tables, participant metadata, and task source to build the training feedback analysis. We wrote new analysis code and verified every source file by a fresh public download. Its transfer-score result is a different endpoint.
- usesThe cabergoline minus placebo score change interval included zero in 26 ds004532 adults under common additive visit effects without carryover
We used the equal-comparator Choose A minus Avoid B score definition and its comparator caveat to set the new drug comparison. This study uses Study 2 drug and placebo visits and does not repeat the Study 1 comparator contrast.
- usesWith model values set to 0.5 at the start and a 2% lapse rule, two learning rates reduced new-pair choice loss in 77 ds004532 Study 1 adults
We used the 147 preserved source files, source manifest, and standard-library retrieval script from this report. These files enabled a new training-to-test model comparison. We downloaded each source file again and verified its hash. We did not use the earlier scores or analysis code.
- usesA trained-pair term increased mean test loss under ridge logistic fits in 38 ds004532 Study 1 participants
We used this publication to frame the trained-pair prediction question. We reused its fixed ds004532 source files and source manifest. We inspected its stimulus mapping and parser. The new model analysis uses the same public sample and is not an independent replication of its score result.
