Recent advances in autonomous systems can reduce operator SA, so researchers have sought real-time, nondisruptive indicators of SA to enable SA-based adaptive cooperation in human-autonomy teams. However, gold-standard freeze-probe measures of SA are not validated for use as ground truth in real-time predictive models. Working memory constraints force single-trial measures to be partial by nature. Existing workarounds smooth over temporal dynamics, precluding real-time predictive models. This work shows that a 3-trial moving average SA score reduces measurement noise while preserving temporal information. Moving average scores are more strongly correlated (<i>r</i> = 0.36, <i>p</i> < 0.01) with performance than single trial SA scores and can be predicted by single-trial physiological signals with greater accuracy (standardized mean absolute error = 0.61, <i>Q</i><sup>2</sup> = 0.36) than single trial SA scores.</p>","PeriodicalId":50503,"journal":{"name":"Ergonomics","volume":" ","pages":"2124-2134"},"PeriodicalIF":2.8,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145070934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drawing on fairness heuristic theory and the mutual verification of 269 two-wave time-lagged surveys and 303 cross-sectional surveys from gig workers working on different digital platforms in China, we demonstrate that interactional justice fully mediates the positive effect of platform work flexibility and the negative effect of platform work insecurity on affective commitment to the platform.
