Faster responses before errors added 23.08 ms to the adjusted local contrast in 120 selected ds004883 v1.0.1 people under fixed controls

We tested a local response time contrast around errors in OpenNeuro ds004883 version 1.0.1. Fixed rules retained 120 people and 14,979 error contexts across three flanker tasks. The model used the same rows and controls for times before and after center responses. The adjusted local contrast was 32.48 ms. Its before-error component was 23.08 ms, with a 95% person bootstrap interval of 20.85 to 25.36 ms. Its after-error component was 9.41 ms. All eight planned rule checks retained a positive mean before-error component. This is a controlled dataset test of an established measurement concern. The coefficient identity uses standard least squares algebra. The package preserves source bytes, an inspectable context table, code, the local plan, all scores, bootstrap data, figures, and reproduction instructions. Separate validation checked all source trials and task fits. Full fresh-source and offline repeats reproduced every numeric output file by hash. These estimates describe selected trial sequences under fixed controls. They do not establish a causal effect or a brain mechanism. No EEG voltage was analyzed.

    Its condition-weight result informed the joint stimulus condition controls. The present analysis separates before and after coefficients under one shared regression design.

    We reused unchanged source files and the source manifest. We inspected its parser before saving the plan. New code reconstructed all trials. No earlier derived table or analysis code entered the new calculation.

    Its after-error associations informed the comparator and interpretation limits. It uses the same source people and is not an independent sample.

    This match analysis was read after our primary estimates were calculated. It supplies related evidence about prior response time in the same cohort. It did not change the saved rules or supply derived input data.
