Verbal Intent and Gaze Cues on Action Prediction in ASD

13 maj 2026 uppdaterad av: Shan Gao, University of Electronic Science and Technology of China

Exploration of Verbal Intention and Gaze Clues Characteristics in Children With Autism: Based on Eye Tracking Technology

A 2×2×3 mixed design (intent word × object type × group: TD, ASD, ID) was used. Age-matched children watched videos and judged which object a model would pick; their choices and eye movements were recorded.

Detaljerad beskrivning

A 2 (intent word: like, dislike) × 2 (object type: mentioned, unmentioned) × 3 (participant group: ASD, TD, ID) mixed experimental design was adopted. Children from the three age-matched groups (29 TD, 22 ASD, 24 ID) completed a video-watching task. In the video, a model was presented with two objects and uttered a sentence containing an intent word, a verb, and a noun, such as "I like to eat oranges." Based on the intent word, trials were divided into "like" and "dislike" conditions. Objects were classified as "mentioned" or "unmentioned" according to the verb and noun used. Participants were required to judge which object the model would pick while watching the video. Their choice responses and eye movements were recorded.

Studera befolkning

A total of 80 children (aged 3-10 years) were initially recruited and divided into three groups: 29 typically developing (TD) children (25 boys, 4 girls) from a kindergarten or primary school in Sichuan Province; 26 children with autism spectrum disorder (ASD) (20 boys, 6 girls) from a local disability federation or autism rehabilitation center in Chengdu, Sichuan Province, all clinically diagnosed and assessed with the Autism Diagnostic Observation Schedule (ADOS); and 25 children with intellectual disability (ID) (14 boys, 11 girls) from a disability federation or rehabilitation center in Chengdu, Sichuan Province, all clinically diagnosed. Based on eye-tracking data, 4 ASD participants and 1 ID participant whose total fixation duration accounted for less than 50% of the total trial time were excluded. Consequently, the final sample included 29 TD children (25 boys, 4 girls), 22 ASD children (18 boys, 4 girls), and 24 ID children (13 boys, 11 girls) for data analysis.

Vad mäter studien?

Primära resultatmått

Resultatmått	Åtgärdsbeskrivning	Tidsram
Percentage of Total Fixation Duration on Objects Tidsram: During the full 13 seconds video presentation	Percentage of Total Fixation Duration on Objects = (Total time fixating on target objects ÷ Total fixation duration across the scene) × 100%. It measures how much of overall viewing time is spent attending to predefined objects, reflecting attentional priority and object-driven cognitive engagement, normalized for individual differences.	During the full 13 seconds video presentation
The time to first fixation on an object within each defined TOI (Time of Interest) Tidsram: During the 0-2 s, 2-6 s, and 6-8 s intervals of video	Time to First Fixation on an Object within a TOI = time elapsed from TOI onset until the first fixation lands on that object. It measures how quickly attention is drawn to a target, reflecting salience or search efficiency. Shorter times indicate faster capture.	During the 0-2 s, 2-6 s, and 6-8 s intervals of video
