| Abstract |
| In addition to well-documented impairments in social communication and interaction, individuals with autism spectrum disorder (ASD) frequently demonstrate atypical perceptual and cognitive processing across multiple levels. Prior research has consistently reported difficulties in the perception of global coherent motion and biological motion (BM) in individuals with ASD. However, evidence regarding the nature and extent of BM perception impairments remains inconclusive, with studies reporting heterogeneous findings. Because BM conveys not only kinematic motion cues but also socially and emotionally relevant information, a comprehensive evaluation of BM perception in ASD necessitates consideration of both perceptual and contextual influences. This study examined whether children ASD and typically developing (TD) children differ in their perception of partially scrambled BM stimuli as human movement. In addition, global motion perception was assessed using a coherent motion detection task. The results demonstrated that children with ASD performed significantly worse than TD children on the coherent motion task, indicating impairments in global motion processing. In contrast, no significant group differences were observed in judgment criteria for partially scrambled BM stimuli. These findings suggest that although children with ASD exhibit deficits in global motion perception, the availability of social and contextual cues embedded in BM stimuli may support and enhance their perceptual judgments. |
