Longer waits were linked to faster PVT responses in 85 ds000201 v1.0.3 adults if event clocks mark signals

We tested whether one night of assigned sleep restriction changed the relation between wait time and response speed. We used 85 adults with two visits in OpenNeuro ds000201 v1.0.3. The age bands were 20–30 and 65–75 years. The restricted visit followed a three hour sleep opportunity. The main model assumes that event clocks mark signals. It used 7,556 original adjacent response pairs from the first 300 clock seconds. Longer waits were linked to faster responses in both conditions. The mean wait coefficient was 0.11668 inverse seconds per second of wait. Its 95% interval was 0.10692 to 0.12653. The restricted minus full coefficient was 0.00046, with interval −0.01435 to 0.01526. All seven planned checks left the sleep change uncertain. The data do not show equal conditions or a neural mechanism. The clock meaning remains unverified. The package contains source files, hashes, a saved plan, code, all results, and exact bootstrap draws. An independent reader and coefficient calculation agreed. Two repeat runs produced 31 analysis files with identical hashes.
