We conducted a modified paired-choice preference assessment and used a multielement design to examine the effects of noncontingent access to high- and low-preference music on vocal stereotypy exhibited by children with autism. For 3 of the 4 participants, high-preference music (a) produced lower levels of vocal stereotypy than low-preference music and (b) reduced vocal stereotypy when compared to a no-interaction condition. Results underscore the potential importance of assessing musical preference prior to using noncontingent music to reduce vocal stereotypy.
我们进行了改良的配对选择偏好评估，并采用多元素设计来研究非关联获得高低偏好音乐对自闭症儿童发声刻板行为的影响。对于 4 名参与者中的 3 名，高偏好音乐（a）比低偏好音乐产生的发声刻板行为水平更低，（b）与无相互作用条件相比减少了发声刻板行为。研究结果强调了在使用非关联音乐来减少发声刻板行为之前评估音乐偏好的重要性。
