Correct first responses were slower when wrong cues agreed on double-conflict MSIT trials in 39 adults

This study tested wrong cue agreement within double-conflict MSIT trials in OpenNeuro ds004621 version 1.0.4. The planned first key error difference was 1.96 percentage points in 42 adults. Its 95% person bootstrap interval was -0.14 to 4.02 points. This result remained uncertain. In a supporting test, correct first responses were 29.27 ms slower when the wrong cues agreed. Its interval was 20.11 to 38.25 ms. This test used 39 people and correct first responses from 150 to 1500 ms. The contrast gives equal weight to six target and position pairs, then to people. The package also supplies exact behavioral links to EEG events for 37 people. Five people had task sequence differences and received no bridge. Original hit labels differed from first key accuracy on 831 of 4,127 double-conflict trials. The package preserves 301 source files, hashes, code, trials, bootstrap samples, figures, and reproduction instructions. Independent checks and a clean reproduction run passed. The results assume the stated digit key mapping. They describe this cohort and these response rules, without a causal or neural claim.
