Effects of SD stimuli on pilots are usually quantified using control errors, but effects on cognition have not yet been successfully quantified.MethodMilitary helicopter pilots (n = 14) performed scenarios with six SD stimuli (SD condition) and six corresponding control stimuli (NoSD condition) in a motion-base simulator with integrated virtual reality headset. SD stimuli were: false horizon, featureless terrain, leans, brownout, a somatogyral yaw illusion, and loss of horizon due to night vision goggles (NVGs). Mental workload was measured using auditory arithmetic task performance and attentional focus was measured using eye-tracking.ResultsAverage arithmetic task performance was significantly impaired, and proportional gaze dwell time on the attitude indicator was significantly increased in the SD compared to the NoSD condition. Of the six SD stimuli, the featureless terrain, the leans, and the brownout induced significant effects on performance, whereas the featureless terrain, brownout, and false horizon significantly affected gaze behavior. The NVGs and somatogyral yaw stimuli did not induce significant effects. Pilots' self-reports indicated awareness of all SD stimuli, except for the featureless terrain.ConclusionThe results indicate that SD impacts pilot mental workload and attentional focus.ApplicationModern military aircraft present a large volume of mission-related information to pilots. This study shows that SD stimuli may negatively impact the processing of such information.","PeriodicalId":56333,"journal":{"name":"Human Factors","volume":" ","pages":"997-1010"},"PeriodicalIF":3.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12420934/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144057732","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}

Despite this, there is a lack of comprehensive understanding regarding the capabilities and limitations of the existing testbeds.MethodWe first developed a taxonomy for HATs by modifying the existing framework for classifying human teams. Our proposed taxonomy comprises ten attributes. Subsequently, using the taxonomy, we analyzed 103 testbeds identified from 235 empirical research studies. After coding each testbed, we conducted frequency analyses on each attribute to determine the distribution of the testbeds.ResultsRegarding team composition, the majority of testbeds afford single human participants paired with few agents, typically in subordinate roles. Also, in most testbeds, the leadership structure is designated, with humans assuming leadership roles, or none. The communication dynamics present an area for further exploration, especially with larger team sizes. Additionally, nearly all reviewed testbeds focus on long-term teams, overlooking dynamics in ad hoc teams, which are common in real-world settings.ConclusionOur findings underscore the importance of further research into diverse team attributes, such as team composition, leadership structure, communication structure, direction, and medium. It would facilitate a deeper understanding of complex team dynamics in HATs and lead to designing effective teams.ApplicationThe current study would be valuable for discussing future research directions when developing new testbeds or designing novel experiments leveraging existing ones.","PeriodicalId":56333,"journal":{"name":"Human Factors","volume":" ","pages":"187208251376898"},"PeriodicalIF":3.3,"publicationDate":"2025-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145058813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, prior work has found a relatively negligible role of head movements associated with performance costs. However, currently no studies have examined the magnitude of costs for spatial integration tasks when information is separated laterally using an AR-HMD.MethodsParticipants completed a spatial integration task in which information to be integrated was separated by multiple lateral visual angles. Participants were required to judge whether XY coordinate numbers were located within a designated red zone presented on a map.ResultsA significant effect of separation distance was found on response time, with no impact on accuracy. The effect of separation on response time increased considerably in the AR-HMD format compared to prior work examining the performance costs on a wide-angle monitor. Head movements became more costly to response time once information began to enter the head field at around 32 degrees of separation.ConclusionsThe current results taken with previous work indicate a task-device interaction, in which head movements become more costly dependent upon the type of information to be integrated.ApplicationOur findings imply the need for careful evaluation of task characteristics when modeling information separation costs on a desktop display for an AR-HMD format.","PeriodicalId":56333,"journal":{"name":"Human Factors","volume":" ","pages":"187208251377311"},"PeriodicalIF":3.3,"publicationDate":"2025-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145031423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

E-learning became mandatory to use and was met with varying degrees of acceptance by students, whose educational expectations and experiences were altered. By 2022, institutions began transitioning to optional e-learning use, creating a natural setting to examine technology acceptance under both voluntary and involuntary conditions.MethodThis study employed a two-phase approach, first validating an extended Technology Acceptance Model (TAM) incorporating seven factors derived from focus groups. Second, conducting multigroup analysis of acceptance between voluntary and involuntary users. Data was collected through surveys from 908 undergraduate students.ResultsPLS-SEM analysis revealed strong explanatory power (R2 = .463-.731) for the extended TAM framework. Compatibility demonstrated the strongest effect on perceived usefulness, while information quality and system quality influenced both perceived usefulness and ease of use. Multigroup analysis revealed significant contextual differences in students' acceptance. Perceived ease of use more strongly influenced behavioral intention for voluntary users, while perceived usefulness had stronger effects for involuntary users.ConclusionThe extended TAM framework significantly predicted e-learning acceptance in both voluntary and involuntary contexts.

Evaluated measures included muscle activity in left (LES)/right (RES) erector spinae and left (LBF)/right (RBF) biceps femoris muscles, endurance, and user perspectives. Temporal effects of fatigue were examined by categorizing muscle activity based on perceived exertion level with Borg scale.ResultsBSIE reduced low-back (LES, RES), and leg (LBF, RBF) mean amplitude by ∼ 18-24% and ∼10-17% respectively. Benefits of BSIE in low-back reduced by ∼11-15% at medium versus low fatigue.
