“…On this point, changes in arousal and attention to facial expressions may be important. As noted above, the research indicates that individuals with ASD have atypical activity in the amygdala [23] and atypical attentional allocation for facial expression [19,20,43]. Thus, the atypical nature may influence the temporal ensemble of individuals with ASD.…”

A series of multiple facial expressions can be temporally perceived as an averaged facial expression in a process known as ensemble perception. This study examined the effect of temporal parameters on the perceived intensity of facial expression in each emotion, and how the effect varies with autistic traits in typically developing people. In the experiment, we presented facial expressions that switched from emotional to neutral expressions, and vice versa, for 3 s. Participants rated the overall perceived intensity of the facial emotions as a whole rather than rating individual items within the set. For the two tasks, a ratio of duration of emotional faces to duration of neutral faces (emotional ratio) and the timing for transitions were manipulated individually. The results showed that the intensity of facial emotion was perceived more strongly when the presentation ratio increased and when the emotional expression was presented last. The effects were different among the emotions (e.g. relatively weak in the anger expression). Moreover, the perceived intensity of angry expressions decreased with autistic traits. These results suggest that the properties and individual differences in the facial ensemble of each emotion affect emotional perceptions.

“…As mentioned earlier, the Tobii eye-tracking system is widely used for studying the pupillometry of ASD [39]. Several researchers used eye-tracking signals to study different cognitive and social functions of ASD, including facial emotional expressions [44], visuospatial orienting [45], emotion-discrimination task [46], reading comprehension skills [47], social images [48], and gaze cue in a face-following task [49]. A decreased fixation duration for social stimuli has been consistently identified in individuals with ASD [29], [43].…”

The design goals of recently developed serious games are to improve attention, affective recognition, and social interactions among individuals with autism. However, most previous studies on serious games used behavioral questionnaires to evaluate their effectiveness. The cognitive assessment of individuals with autism after behavioral intervention or drug treatment has become important because it provides promising biomarkers to assess improvement after cognitive intervention. In this study, we developed a game-based social interaction platform incorporating an eye-tracking system for children and preadolescents with autism. Three modules (focusing on gaze following, facial emotion recognition, and social interaction skills) are included in the platform; participants with autism learn these according to their cognitive abilities. The eye-tracking results showed decreased fixation durations when autistic children looked at positive emotional expressions and focused on multiple targets. Prolonged saccade durations and shorter fixation times for socialrelated facial emotion expressions were also found in preadolescents and teenagers with autism. Our findings suggest that these atypical gaze patterns are reliable biomarkers for evaluating the social and cognitive functions of autistic individuals while playing serious games. The proposed platform's game-based modules and the findings regarding aberrant gaze patterns in autistic individuals demonstrate the possibility of evaluating cognitive functions and intervention effectiveness by using eye-tracking signals in a serious game or real-life environment.
