简要总结
To examine whether the spatiotemporal organization of gaze strategies differs between children with autism spectrum disorder (ASD) and typically developing (TD) children during a staged joint attention interaction, and to identify at which phase differences emerge.
详细描述
This cross-sectional observational study involved children with ASD and their typically developing (TD) peers freely viewing dynamic social interaction videos. The videos were segmented into four theory-driven phases: Introduction (scene establishment), Joint Attention (mapping another's gaze to an object preference), Intentional Comprehension (inferring the model's intention), and Emotional Feedback (evaluating outcomes that were either congruent or incongruent with the established preference). Participants' eye movements were recorded throughout using a remote eye-tracker.
