Social partners tend to coordinate their behaviors in time. This "interactional synchrony" is associated with a host of positive social outcomes, making it ripe for study in autism spectrum disorder (ASD). Twenty children with ASD and 17 typically developing (TD) children participated in conversations with familiar and unfamiliar adults. Conversations were rated for movement synchrony and verbal synchrony, and mothers completed measures regarding children's everyday social and communication skills. Children with ASD exhibited less interactional synchrony, with familiar and unfamiliar partners, than TD peers. Beyond group-level differences, interactional synchrony negatively correlated with autism symptom severity, and predicted dimensional scores on established social and communication measures. Results suggest that disrupted interactional synchrony may be associated with impaired social functioning in ASD.
社会伙伴往往倾向于在时间上协调他们的行为。这种“互动同步”与许多积极的社会结果相关,因此非常适合研究自闭症谱系障碍(ASD)。20 名 ASD 儿童和 17 名典型发育(TD)儿童与熟悉和不熟悉的成年人进行对话。对话的动作同步性和语言同步性进行了评分,母亲则完成了关于孩子日常社交和沟通技能的测量。与 TD 同龄人相比,ASD 儿童与熟悉和不熟悉的伙伴互动时表现出较少的互动同步性。除了群体水平的差异外,互动同步性与自闭症症状严重程度呈负相关,并预测了既定社交和沟通测量的维度得分。研究结果表明,互动同步性的破坏可能与 ASD 中的社交功能障碍有关。
