Brief Report: Visual Perception, Task-Induced Pupil Response Trajectories and ASD Features in Children.
We applied a trajectory-based analysis to eye tracking data in order to quantify individualized patterns of pupil response in the context of global–local processing that may be associated with autism spectrum disorder (ASD) features.

| Sumario: | We applied a trajectory-based analysis to eye tracking data in order to quantify individualized patterns of pupil response in the context of global–local processing that may be associated with autism spectrum disorder (ASD) features. Multiple pupil response trajectories across both global and local conditions were identified. Using the combined trajectory patterns for global and local conditions for each individual, we were able to identify three groups based on trajectory group membership that were thought to reflect perceptual strategy. Results indicated that the proportion of children with ASD was significantly greater in the group demonstrating a local-focus response. This research presents a novel analytic approach to the objective characterization of individualized pupil response patterns that are associated with ASD features. |
