Outcome Measures

Primary Outcomes (3)

The proportions of fixation duration
The fixation duration proportion for each area of interest (AOI) was calculated as the ratio of the fixation duration of different AOIs (face, hand) to the total fixation duration of the screen.
During the first 13 seconds video presentation.
The proportion of fixation duration on the screen displaying correct answers
The ratio of gaze duration on the correct answer screen to total gaze duration during the stage when judging whether the model wanted or did not want the new toy.
Experimental material video from 18 seconds to 26 seconds
Changes in cerebral cortex blood oxygen concentration
Changes in blood oxygen concentration in the cerebral cortex were monitored throughout the entire experimental procedure.
Each trial lasts 26 seconds, followed by a 20-second rest interval, for a total of 18 trials.

Study Population

An estimated 90 Chinese children participated in this study, with 30 in the TD group, 30 in the ASD group, and 30 in the ID group. Children with ASD and ID were recruited from private or public specialist schools in Chengdu, while TD children were from primary school and kindergarten in Shehong City, Sichuan Province. The average age was 7 years old, including 15 males and 15 females in each group. Eye-tracking data with a sampling rate below 70% will be excluded from analysis.
