Vocal, gestural, and graphic communication modes were implemented concurrently with a toddler with Angelman syndrome to identify the most efficiently learned communication mode to emphasize in an initial augmentative communication system.
Symbols representing preferred objects were introduced in vocal, gestural, and graphic communication modes using an alternating treatment single-subject experimental design. Conventionally accepted prompting strategies were used to teach symbols in each communication mode. Because the learner did not vocally imitate, vocal mode intervention focused on increasing vocal frequency as an initial step.
When graphic and gestural mode performances were compared, the learner most accurately produced requests in graphic mode (percentage of nonoverlapping data = 96). Given the lack of success in prompting vocal productions, a comparison between vocal and the other two communication modes was not made.
A growing body of evidence suggests that concurrent modality sampling is a promising low-inference, data-driven procedure that can be used to inform selection of a communication mode(s) for initial emphasis with young children. Concurrent modality sampling can guide clinical decisions regarding the allocation of treatment resources to promote success in building an initial communicative repertoire.
同时采用言语、手势和图形交流模式与一名安格曼综合征的幼儿进行交流，以确定在初始的辅助沟通系统中强调最容易学习的沟通模式。
采用交替治疗的单一被试实验设计，在言语、手势和图形交流模式中引入代表偏好对象的符号。在每个交流模式中使用传统的提示策略来教授符号。由于学习者不能模仿言语，言语模式干预侧重于增加言语频率作为初始步骤。
当比较图形和手势模式的表现时，学习者在图形模式下最准确地发出请求（非重叠数据百分比=96%）。由于在提示言语产生方面缺乏成功，因此没有对言语和其他两种交流模式进行比较。
越来越多的证据表明，同时采用多种模式取样是一种有前途的低推断、数据驱动的程序，可以用来告知选择一种（多种）交流模式作为幼儿初始强调的重点。同时采用多种模式取样可以指导临床决策，以分配治疗资源，促进建立初始沟通能力。
