3-back false alarm odds were higher at lag 2 than lag 1 in 60 women from ds007022. A common odds model used single matches in four prior trials.
We tested letter history in OpenNeuro ds007022 version 1.1.0. The sample had 60 women and three visits. The main analysis used 3-back non-targets with one letter match in four prior trials. False alarms occurred on 52 of 445 lag 1 trials and 152 of 532 lag 2 trials. A common odds model compared the lags within each person and visit. The lag 2 to lag 1 odds ratio was 3.23. Its whole-person bootstrap 95% interval was 2.08 to 5.36. Response markers, an eight-letter history, target exclusions, and trial position checks also gave higher odds at lag 2. This result describes the released task and sample. It does not identify a neural cause or a training effect. The package preserves 186 source files, 27,000 annotated trials, all 20,000 bootstrap samples, code, and repeat instructions. Fresh downloads matched the source hashes. An analysis of the new downloads gave identical result files. Independent probability and source calculations checked the method. The general n-back lure effect was known before this study.

We obtained 186 source files from this preserved archive and read its response window audit. Fresh downloads verified every file. We wrote new code for the trial history comparison. The studies use the same cohort.

This work uses the pinned source manifest and retrieval code. The earlier lag-specific descriptions were known before the local analysis plan. The new analysis compares later-visit predictions.
- usesThe refitted 95% interval included zero for the gain from four order terms at later n-back visits in 60 women from ds007022. The test used ridge penalty 1 and assumed independent people.
We retrieved the 186 source files, source manifest, and version record from this archive. Fresh public downloads verified every source file. Its known lag contrast led to the new prediction question. We wrote new analysis code and used the same cohort.
