However, other research suggests skilled readers recognize words faster when they appear in predictable and/or plausible contexts, despite efficient bottom-up processing. Research on individual differences in skilled comprehension suggests skilled readers only use context to support word recognition when bottom-up processing is slow. Therefore, highly skilled readers may not rely on context, but less-skilled readers may continue to rely on context during word recognition due to poor bottom-up processing. The current study investigated whether individual differences in lexical quality would influence contextual processing during word recognition. Participants' eye movements were tracked as they read sentences containing either a high-frequency (e.g., baby) or low-frequency (e.g., elbow) target word preceded by either a related prime word (mother-baby) or an unrelated control word (teeth-elbow). Results show relatedness had a significant effect on readers across the range of lexical knowledge; however, the specific effect depended on both vocabulary and target word frequency. The results suggest that context supports word recognition and comprehension when readers have adequate vocabulary.","PeriodicalId":15813,"journal":{"name":"Journal of Eye Movement Research","volume":"19 5","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13600167/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149030692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a sensor-based in-vehicle interface, the augmented reality head-up display (AR-HUD) integrates real-time environmental sensing with visual information delivery, yet how different information presentation strategies influence driver visual attention during takeover remains underexplored. We examined the effects of presentation form (static/dynamic) and presentation timing (concurrent/progressive) using a 2 × 2 within-subject design. In the experiment, twenty-one licensed drivers viewed prerecorded automated driving takeover scenarios. Eye tracking measured mean fixation duration, mean saccade amplitude, time to first fixation, and fixation count, while ratings assessed usability, acceptance, and intention comprehension. Progressive presentation significantly reduced all eye-tracking measures and improved perceived usability ratings compared with concurrent presentation. This pattern indicates more concentrated and orderly gaze allocation and is consistent with lower visual-search and information-integration demands. However, the lower fixation count may partly reflect reduced information exposure. Static presentation reduced mean fixation duration but showed no consistent overall advantage on the remaining measures. Significant form-by-timing interactions showed that progressive presentation reduced saccade amplitude and time to first fixation and improved intention comprehension under static, but not dynamic, presentation. Among the four combinations, static-progressive presentation yielded the most favorable overall pattern. Overall, presentation timing affected more measured outcomes than presentation form. These findings provide preliminary evidence that presentation form and presentation timing shape gaze behavior and subjective evaluations of AR-HUD takeover displays.","PeriodicalId":15813,"journal":{"name":"Journal of Eye Movement Research","volume":"19 4","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13513926/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148828990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While well-documented in adults, the contribution of eye movements to children's silent reading speed and grade-related changes remain underspecified. Furthermore, the distributional properties of fixation durations have rarely been examined in children. This study investigates how changes in eye-movement parameters associate with individual differences in children's silent reading speed. The eye movements of 194 typically developing Greek-speaking students (Grades 3-6) were recorded during silent reading of short passages. An Ex-Gaussian distributional analysis was applied to fixation durations, alongside traditional measures of mean fixation number, fixation duration, and saccade amplitude. Language and cognitive abilities were also evaluated. Silent reading speed increased with grade, driven by fewer and shorter fixations, and longer saccades. After accounting for age, vocabulary and cognitive measures, eye-movement parameters increased the explained variance in silent reading speed to 80% (adjusted R2 = 0.800) in the full sample (N = 194). The Ex-Gaussian parameter τ was an independent predictor, distinct from mean fixation duration. Finally, age significantly moderated the association between forward fixations and silent reading speed. These findings indicate that oculomotor behavior is independently linked to children's silent reading speed across primary school years, as captured both by conventional and distributional oculomotor parameters.","PeriodicalId":15813,"journal":{"name":"Journal of Eye Movement Research","volume":"19 4","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13514566/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148829365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eye tracking provides a process-oriented methodology for examining how such tasks are visually guided, with implications for human behavior analysis, operator support, and automation design. The present study investigated the potential of specific eye and gaze metrics to reflect differences in task condition and process dynamics during human disassembly. These were analyzed using a dimension-based mixed-effect modeling approach, accounting for task condition, handcraft skill levels, and task duration across repeated observations within participants, addressing four dimensions: visual attention allocation, cognitive workload, scanpath structure, and gaze organization. The results showed that increased task uncertainty was most associated with shorter fixation durations, higher fixation rates, larger pupil diameters, and higher revisit rates, indicating intensified visual sampling, increased cognitive workload, and repeated checking behavior. No robust differences were observed between skill levels. A longer task duration, as an indirect proxy of less routine-like execution, was primarily reflected in fixation dynamics and scanpath structure, rather than in entropy or workload measures. The findings demonstrate the sensitivity of eye and gaze metrics to task uncertainty and process dynamics in disassembly.","PeriodicalId":15813,"journal":{"name":"Journal of Eye Movement Research","volume":"19 4","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13514580/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148829224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

HVP predicts that experts make longer saccades to construct a holistic representation of the visual scene and facilitate target detection. Our previous work challenged this prediction by showing that expert architects made shorter, rather than longer, saccades during visual search. The present study investigated how this atypical search strategy develops by comparing expert architects, intermediate architects, and naïve observers performing the same visual search task. Intermediate architects exhibited shorter saccades than naïve observers, but not to the extent observed in experts, while demonstrating search efficiency intermediate to the two groups. Analyses of the temporal organization of search further revealed that intermediate architects had already adopted the overall structure of the expert search strategy despite not yet exhibiting expert-level reductions in saccadic amplitude. These findings suggest that perceptual expertise in architecture develops through a layered progression in which the organization of visual search precedes the full refinement of eye movement behavior. More broadly, these findings suggest that eye movement research should interpret gaze metrics such as saccadic amplitude within the context of domain-specific task demands and developmental stage, while considering the temporal organization of search as an additional window into the emergence of perceptual expertise.","PeriodicalId":15813,"journal":{"name":"Journal of Eye Movement Research","volume":"19 4","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13513633/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148829160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

How source-attribution visualization shapes the visual preconditions of verification remains unknown: users can notice, read, or compare a source without clicking. This within-subjects eye-tracking study (N = 23; 92 trials) evaluated four attribution visualizations abstracted from commercial AI chatbots and rendered as simulated screens: inline component (sentence-end chips), card list (cards above the answer), side panel (adjacent panel), and raw hyperlink (bare URLs), combining gaze metrics, surveys, and interviews. Repeated-measures ANOVAs revealed strong layout effects on source discoverability and engagement, largely robust to sensitivity checks (the panel's discovery latency was order-sensitive): the card list was discovered almost immediately, with the raw hyperlink last. Yet no self-reported measure differed detectably. The most frequently nominated format, the inline component, attracted about half the dwell time of the stand-alone formats, whose prolonged fixations suggested citation-to-text mapping cost rather than genuine engagement. This attention-preference gap means both must be measured jointly. We contribute a four-layout gaze-based comparison, a reproducible participant-level analysis workflow, and three design principles (pre-click identifiability, sentence-level claim-source mapping, and in situ preview) within a proposed two-stage attribution architecture.","PeriodicalId":15813,"journal":{"name":"Journal of Eye Movement Research","volume":"19 4","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13513764/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148829227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using eye-tracking methods within experimental guessing games featuring interior equilibria, we analyze how strategic complementarity and substitutability alter choice behavior and cognitive engagement. We find that while choices diverge further from equilibrium under strategic complementarity, eye gaze metrics-specifically fixation and transition measures-are consistent with more intensive cognitive engagement under strategic substitutability. Furthermore, by using a novel approach to measure strategic sophistication, we find that individuals with higher strategic aptitude exhibit higher levels of visual engagement with the payoff table. As strategic sophistication increases, the two distinct dimensions of attention build up sequentially rather than together, with attention to an individual's own strategies strengthening prior to attention to their opponents'. These findings indicate that visual attention is shaped systematically by the strategic environment and are consistent with a sequential organization of reasoning that may underlie the strategic environment effect.","PeriodicalId":15813,"journal":{"name":"Journal of Eye Movement Research","volume":"19 4","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13514219/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148829155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing direction-guided methods usually reduce gaze direction to a single vector or spatial mask. This deterministic treatment can obscure directional ambiguity, discard coexisting candidate directions, and propagate early estimation errors to gaze target localization when head cues are weak or multiple targets are plausible. To address these limitations, we propose an uncertainty-aware framework based on Circular Direction Distribution Learning (CDDL) and Probabilistic Gaze Geometry Modeling (PGGM). CDDL represents gaze direction as a 72-bin circular probability distribution under von Mises soft supervision, thereby preserving neighboring directional hypotheses before target localization. Rather than predicting a target space distribution directly, PGGM aggregates the direction distribution into 18 groups and projects the retained hypotheses into cone-like spatial probability fields, allowing spatial tolerance to expand with distance while preserving a channel-wise direction-to-region representation. The full probability volume is fused with the RGB scene image at the input level and processed by a ResNet-50-FPN network for gaze heatmap prediction. Controlled experiments on GazeFollow demonstrate competitive localization and support the contribution of direction-distribution learning and channel-wise geometric projection. Zero-shot transfer, dataset-level uncertainty and failure analyses, efficiency measurements, and qualitative results further indicate interpretable behavior together with domain-dependent and computational trade-offs.","PeriodicalId":15813,"journal":{"name":"Journal of Eye Movement Research","volume":"19 4","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13514171/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148829187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
