However, little is known about how prior expectations and new information about target prevalence interact in simulated emergency scenarios.MethodsParticipants (<i>n</i> = 48) received training where the average number of hazards (explosive cylinders) amongst similar distractors was varied (two or six) before participants rescued a trapped person. Trial-end feedback indicated whether all targets were removed and the person rescued. They were then instructed that hazard prevalence would increase, decrease, or stay similar during test blocks. Stress was manipulated by an ongoing alarm, the threat of trial-ending explosions, and reduced movement speed. Search performance was measured by the number and type of stimuli removed and stress was assessed using self-report and physiological measures.ResultsAcross high and low stress conditions, more hazards were removed and more false positives occurred (i.e., more distractors removed) when test prevalence was lower than during training, compared to when prevalence levels remained similar. False negative errors were consistently low across conditions.ConclusionAcquired hazard expectations can override explicit instructions, leading to persistent search errors, likely due to difficulties in adjusting decision criteria.ApplicationThese results suggest that training in high-stakes hazard search should incorporate the use of tools and techniques to help mitigate the persistent influence of outdated expectations on search performance.</p>","PeriodicalId":56333,"journal":{"name":"Human Factors","volume":" ","pages":"580-598"},"PeriodicalIF":3.6,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13013653/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145913897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent advances in computer vision offer opportunities to automate this process.MethodThe proposed method follows a three-stage process: (1) BlazePose, a real-time pose estimation model, detects 22 key body joints, followed by low-pass filtering to reduce noise. (2) Kinematic features are extracted from these joints, and video frames are classified as lifting or nonlifting to identify lifting phases and lift start and end times. (3) RNLE multipliers are estimated at these lift timings to compute the recommended weight limit (RWL).ResultsThe method achieved a mean absolute timing error of 0.25 s for lift timing identification and showed strong correlations between estimated and ground-truth multipliers. The mean absolute error for RWL estimation was 1.58 kg, with a correlation coefficient of 0.91.ConclusionThese results demonstrate the feasibility of using computer vision to automate the RNLE.

However, providing these directives during sub-maximal tasks may not prompt prioritization of physical performance as individuals self-organize, eventually making the intervention ineffective.MethodsForty participants (50% female) lifted a crate with and without the instruction to avoid rounding the low back.

We assess how the length of explanations and students' expertise shape the likelihood of alignment with AI recommendations.BackgroundThe relationship between explainability and users' trust in AI systems has been scarcely addressed in the current literature, even though AI-assisted processes increasingly affect all professions and hierarchical levels. Given that human-AI relationships are often formed during education, it is crucial to understand how individual and contextual factors influence students' assessment of AI outputs.MethodWe conducted in-class experiments with 248 students from multiple universities. Participants solved GMAT questions, then viewed an AI recommendation-sometimes correct, sometimes incorrect-with varying explanation depth and eventually could revise their initial answer; student's final answer being in line with AI recommendation operationalized our measure of \"trust.\" We estimated logistic models with control variables, including mixed-effects specifications to account for repeated observations.ResultsExplanation complexity is associated with higher trust on average, but its relevance depends on who reads it and whether AI is correct. Students who previously answered correctly exhibited lower willingness to defer, especially when AI was incorrect; conversely, agreement and consistency effects significantly amplified trust. These behavioral patterns highlight conditions under which AI-generated explanations can foster critical engagement or conversely encourage uncritical acceptance.ConclusionOur results point to a \"AI knows better\" heuristic at work-especially among nonexperts-where polished presentation is easily read as reliability, encouraging uncritical agreement with incorrect recommendations; in parallel, experts benefit more from deeper rationales when AI is accurate, yet still display under-reliance of correct assistance in many cases. Overall, trust calibration is driven less by any single cue than by the alignment of student performance, AI reliability, and explanation design, with prior agreement acting as a powerful amplifier of subsequent alignment.ApplicationOur findings imply that instructional approaches should promote independent reasoning before exposure to AI, deploy concise but diagnostically informative explanations, and include brief verification steps before accepting AI recommendations, especially for nonexperts who are more prone to harmful switches.
