Accurately predicting human scanpaths during reading is vital for diverse fields and downstream tasks, from educational technologies to automatic question answering. To date, however, progress in this direction remains limited by scarce gaze data. We overcome the issue with ScanEZ, a self-supervised framework grounded in cognitive models of reading. ScanEZ jointly models the spatial and temporal dimensions of scanpaths by leveraging synthetic data and a 3-D gaze objective inspired by masked language modeling. With this framework, we provide evidence that two key factors in scanpath prediction during reading are: the use of masked modeling of both spatial and temporal patterns of eye movements, and cognitive model simulations as an inductive bias to kick-start training. Our approach achieves state-of-the-art results on established datasets (e.g., up to 31.4% negative log-likelihood improvement on CELER L1), and proves portable across different experimental conditions.

Cognitive science offers rich theories of learning and communication, yet these are often difficult to operationalize at scale. We demonstrate how natural language processing can bridge this gap by applying psycholinguistic theories of discourse to real-world educational data. We investigate linguistic alignment – the convergence of conversational partners’ word choice, grammar, and meaning – in a longitudinal dataset of real-world tutoring interactions and associated student test scores. We examine (1) the extent of alignment, (2) role-based patterns among tutors and students, and (3) the relationship between alignment and learning outcomes. We find that both tutors and students exhibit lexical, syntactic, and semantic alignment, with tutors aligning more strongly to students. Crucially, tutor lexical alignment predicts student learning gains, while student lexical alignment negatively predicts them. As a lightweight, interpretable metric, linguistic alignment offers practical applications in intelligent tutoring systems, educator dashboards, and tutor training.
