Adjusted accuracy and correct response time scores correlated across task halves in 118 selected ds004883 version 1.0.1 participants

We tested whether person scores for accuracy and correct response time after errors agree across tasks and task halves. The source was OpenNeuro ds004883 version 1.0.1. Additive models controlled stimulus conflict, original trial order, and recording segments. In 118 selected people, equal-task scores had first-half and second-half correlations of 0.312 for accuracy and 0.328 for correct response time. Their 97.5% participant bootstrap intervals were 0.123 to 0.483 and 0.184 to 0.505. These two intervals give approximate 95% joint coverage under the stated assumptions. The six full-task pair correlations used 121 selected people. All six descriptive 95% intervals included zero. This does not prove zero agreement. The half scores averaged three tasks; each cross-task score used one task. We did not test a difference between these correlations. A local plan preceded the agreement estimates but followed the starting mean results and related reports. The work does not establish a stable individual trait, clinical reliability, or a causal error effect. The package preserves source files, provenance, code, scores, resamples, checks, figures, and offline instructions. A full repeat matched all 59 numerical file hashes. Separate calculations checked all eight correlations and intervals.

    This report had already established the joint group mean pattern in the same release. Reading it motivated the new test of person score agreement. These studies use the same source data.

    This archive supplied the fixed ds004883 event and metadata files. Its derived trial table was used only for validation. The present work tests person score agreement with new code.

  3. usesA model with independent responses gave a positive accuracy score after errors for 123 ds004883 participants with five time bins sci:sha256:56de945cf32b8c6945ae0fd41e92d78091723ae10d39440914674c531f98e595

    This method report was read after the agreement results. Its independent response calibration informed the stated limits on interpreting fitted accuracy scores. We did not use its code or correct our scores with its estimates.

    This report had already tested joint group means in the same release. Reading it motivated the new agreement question. This work is not an independent replication of its mean result.

    This report compared task and half agreement for mean response time and conflict cost in the same release. It was read during final review and supplied measurement context. The present test concerns error-history coefficients and a different selected cohort.
