This document describes a cued recognition task used to measure the temporal dynamics of social cue processing. In the task, participants are shown a target shape (square or circle) on one hand and a distractor shape (triangle) on the other. Before each trial, a non-predictive cue (head turn) is given that is either valid, pointing to the target location, or invalid. Response times are measured at different stimulus onset asynchronies (SOA) between the cue and shapes to examine how distractors and SOA impact social cue processing. The goal is to use this task to study social cue processing in individuals with autism spectrum disorder.

Editor's Notes
- #4: -Most of the studies found that kids with autism respond reflexively to eye gaze cues, just as typically developed children.-It contradicts the widely accepted notion that children with autism do not engage in joint attention behaviors, such as following someones eye gaze.
- #5: Highly complex social scenes
- #6: Head Directions Expresses Intention and interests of the individual
- #7: Head Directions Expresses Intention and interests of the individual
- #8: Head Directions Expresses Intention and interests of the individual
- #11: Symmetrical interference effect.
- #20: MixedStronger cueing effect in Distractor condition?
- #25: corneal reflection average fixation location accuracy between 0.25 and 0.50
