|
Percentage of Total Fixation Duration on Human Faces during Entire Video
Prazo: During the full 27-second video presentation
|
Percentage of total fixation duration on human faces was calculated as (total fixation duration on all face areas of interest / total fixation duration on the entire video) × 100.
Fixation was defined as gaze maintained within a 1° visual angle for a minimum of 100 ms.
This measure was compared between the ASD and TD groups.
|
During the full 27-second video presentation
|
|
Total Fixation Duration on Human Faces during Entire Video
Prazo: During the full 27-second video presentation
|
Total fixation duration (in milliseconds) on human faces, calculated as the sum of all fixation durations that fell within face areas of interest (AOIs).
This measure was compared between the ASD and TD groups.
|
During the full 27-second video presentation
|
|
Percentage of Total Fixation Duration on Human Faces During Phase 4 (Emotional Feedback) by Condition
Prazo: During seconds 22-27 of the video
|
Percentage of fixation duration on faces was calculated for the emotional feedback phase separately for Preference-congruent and Preference-incongruent trials.
The interaction between Group (ASD vs. TD) and Condition (Congruent vs. Incongruent) was examined.
Higher percentages indicate greater allocation of visual attention to faces during emotional feedback.

Number of Gaze Shifts Between Face and Object Areas of Interest
Prazo: During the full 27-second video presentation
|
The number of saccadic gaze shifts that cross between pre-defined face and object areas of interest (AOIs) was counted.
This was taken as an index of attentional switching between social and non-social information.
|
During the full 27-second video presentation
|
|
Mean Distance of Fixation Points from the Center of the Face Area of Interest
Prazo: During the full 27-second video presentation
|
For each fixation, the Euclidean distance (in degrees of visual angle) from its location to the centroid of the pre-defined face AOI was calculated.
The mean of these distances across all fixations was then computed.
Larger values indicate that gaze tended to fall farther from the faces, reflecting less attention to facial information.
