Comparison of ET index under two RIS in ASD vs. TD.
| Interest stimulation | ET index | ASD | TD | t | P |
|---|---|---|---|---|---|
| High | Pupil size (μm) | 4991.67 ± 155.30 | 2520.87 ± 350.30 | 4.96 | P < 0.01 |
| TFT (ms) | 4853.30 ± 227.43 | 2628.98 ± 203.61 | 7.28 | P < 0.01 | |
| Low | Pupil size (μm) | 2896.35 ± 57.21 | 4687.56 ± 208.36 | −3.66 | P < 0.01 |
| TFT (ms) | 2205.51 ± 180.53 | 5914 ± 387.71 | −8.83 | P < 0.01 |
ET, eye tracking; RIS, restrictive interest stimuli; High, high restrictive interest stimuli (HRIS); Low, low restrictive interest stimuli (LRIS); TFT, total fixation time; ASD, Autism Spectrum Disorder; TD, Typically developing children.
