Video-Based Interventions (VBIs) are those that make use of pre-recorded video footage to assist in the acquisition of a variety of skills and behaviours. This study examined one type of VBI, video prompting, and its effectiveness when combined with backward chaining. Prior research suggests that both VBIs and backward chaining are effective intervention methods for skill acquisition. Using a single-subject multiple baseline design, this experiment expands the current literature by thoroughlyexamining backward chaining and a VBI for the acquisition of the shoe-tying behavior in children with Autism Spectrum Disorder. The results obtained from this study support prior research that VBIs are effective and their effectiveness is influenced by a number of factors. We also found that majority of the participants were able to retain their newly acquired behaviors one week after achieving mastery.
基于视频的干预措施（VBIs）是指利用预先录制的视频片段来帮助人们获得各种技能和行为的措施。本研究考察了一种类型的基于视频的干预措施——视频提示，以及它与逆向链接相结合时的有效性。先前的研究表明，基于视频的干预措施和逆向链接都是技能习得的有效干预方法。本实验采用单被试多基线设计，通过全面考察逆向链接和一种基于视频的干预措施对自闭症谱系障碍儿童系鞋带行为习得的影响，扩展了当前的文献。本研究获得的结果支持了先前的研究，即基于视频的干预措施是有效的，其有效性受多种因素影响。我们还发现，大多数参与者在掌握新行为一周后仍能保持这些行为。
