The present study extended the findings of Watt et al. (J Autism Dev Disord 38:1518-1533, 2008) by investigating repetitive and stereotyped behaviors (RSB) demonstrated by children (n = 50) and typical development (TD; n = 50) matched on developmental age, gender, and parents' education level. RSB were coded from videotaped Communication and Symbolic Behavior Scales Behavior Samples (Wetherby and Prizant 2002) using the Noldus Pro Observer© video software. Children with ASD demonstrated significantly higher frequencies of RSB with body objects excluding categories involving banging or tapping objects or surfaces. Behaviors demonstrated by both groups indicated overlapping RSB profiles at this age. These findings highlight the significance of RSB in the early identification and support the need for future research to further determine ASD-specific RSB.
本研究通过调查具有发展年龄、性别和父母教育程度相匹配的儿童（n=50）和典型发育（TD；n=50）的重复刻板行为（RSB），扩展了 Watt 等人（J Autism Dev Disord 38:1518-1533, 2008）的研究结果。使用 Noldus Pro Observer©视频软件，从录像的交流和象征性行为量表行为样本（Wetherby 和 Prizant 2002）中对 RSB 进行了编码。患有 ASD 的儿童在排除涉及敲击或轻敲物体或表面的身体对象的类别时，表现出显著更高频率的 RSB。两个组表现出的行为在这个年龄表现出重叠的 RSB 特征。这些发现强调了 RSB 在早期识别中的重要性，并支持未来的研究进一步确定 ASD 特定的 RSB。
