Assigned sleep restriction gave an uncertain 300-second PVT slope change in 85 ds000201 v1.0.3 adults under additive visit effects without carryover

We tested whether assigned sleep restriction changed response slowing during a public vigilance test. We used the first 300 seconds of each psychomotor vigilance test (PVT). The sample had 85 paired adults from OpenNeuro ds000201 version 1.0.3. We fit log response-time slopes and balanced assigned visit order within each age group. The model assumes common additive visit effects within age group and negligible carryover. The condition difference was 0.01974 log units over 300 seconds. Its 95% participant bootstrap interval was -0.01839 to 0.05954. The fitted trend multiplier differed by +1.99%, with an interval of -1.82% to +6.13%. Both condition trends were positive. All eight fixed checks had condition intervals that included zero. The result does not establish equal conditions. The package preserves exact source files, hashes, a local plan, code, trial records, bootstrap samples, results, and figures. A second parser and model implementation checked all scores and samples. An offline repeat gave the same hashes for all 35 analysis files. This version permits the two metadata files added by AutoSci retrieval.
