A total of 25 children with ASD and 26 TD children participated in the experiment. Their proportions of fixation duration on the eyes and mouth were analyzed across various social cues, including eye gaze direction, speech type, and mouth movement (moving vs. closed). The results indicated that gaze patterns for the eyes and mouth were similar between the two groups. In the averted eye gaze condition, both groups spent more time fixating on the eyes than in the direct gaze condition. In the mouth-closed condition, gaze fixations were predominantly directed toward the eyes, whereas in the mouth-moving condition, fixations were more frequently directed toward the mouth region. However, the difference in fixation duration proportions between the mouth-moving and mouth-closed conditions was smaller in children with ASD than in TD children, suggesting subtle differences in processing dynamic social information. Furthermore, neither socially-directed nor non-socially-directed speech significantly influenced gaze patterns in either group. This study highlights both the similarities and differences in facial gaze patterns between children with ASD and TD children, providing empirical evidence to enhance our understanding of social attention in autism.

Exploring the impact of autistic traits and anxiety on visual attentional response to angry faces in adults with high autistic traits: An eye-movement study / Jiazuo HUO ; Yu WANG ; Jiabei BAI in Research in Autism Spectrum Disorders, 115 (July 2024)

Two experiments were conducted. In Experiment 1, eye-tracking methodology was used to compare 26 participants with high autistic traits to 26 individuals with low autistic traits. The latency of the first fixation on images of angry faces, neutral faces, and objects during a free viewing task was measured. Anxiety levels were assessed using the Self-rating Anxiety Scale. Experiment 2 utilized an overlap task to examine attentional response patterns toward angry faces in individuals with high and low autistic traits. The findings revealed that participants with high autistic traits displayed a longer latency to first fixation on angry faces during the free-viewing task compared to those with low autistic traits. However, no significant differences were observed for neutral faces and objects. In the overlap task, the group with high autistic traits demonstrated a significantly prolonged latency to first fixation on angry faces in peripheral positions when the central stimulus was a neutral face and the peripheral stimulus was an angry face, relative to the group with low autistic traits. Importantly, when taking anxiety traits into account as a covariate in both experiments, the previously observed group effects no longer remained significant. These results were discussed within the frameworks of social motivation theory and the autism continuum hypothesis.
