Purpose: Eye-gaze methods have the potential to advance the study of neurodevelopmental disorders. Despite their increasing use, challenges arise in using these methods with individuals with neurodevelopmental disorders and in reporting sufficient methodological detail such that the resulting research is replicable and interpretable. Method: This tutorial presents key considerations involved in designing and conducting eye-gaze studies for individuals with neurodevelopmental disorders and proposes conventions for reporting the results of such studies. Results: Methodological decisions (e.g., whether to use automated eye tracking or manual coding, implementing strategies to scaffold children's performance, defining valid trials) have cascading effects on the conclusions drawn from eye-gaze data. Research reports that include specific information about procedures, missing data, and selection of participants will facilitate interpretation and replication. Conclusions: Eye-gaze methods provide exciting opportunities for studying neurodevelopmental disorders. Open discussion of the issues presented in this tutorial will improve the pace of productivity and the impact of advances in research on neurodevelopmental disorders.
