Short logged gaps are linked to slower simple reaction responses in 39 people in ds004621 version 1.0.4

We audited timing records for the simple reaction task in OpenNeuro ds004621 version 1.0.4. The source set has 41 people, 82 logs, and 5,291 stimuli. The logs contain 133 gaps with a median duration of 216.7 ms. The task metadata describes gaps from 700 to 1,200 ms. The main trial rule permits a gap comparison in 39 people. Responses after short gaps are 165.7 ms slower after adjustment for run and linear stimulus position. The 95% person bootstrap interval is 149.4 to 183.0 ms. All 39 person estimates are positive. Six records also have one fewer EEG marker than log event. The package preserves unchanged timing sources, all trial labels, source hashes, code, validation, and reproduction instructions. The result is an association in this archive. It does not establish physical screen timing, a causal effect, or a brain mechanism.
