Augmentative and alternative communication (AAC) applications may differ in their use of display and design elements. Using a multielement design, this study compared mand acquisition in three preschool-aged males with autism spectrum disorder, across three different displays in two iPad(®) AAC applications. Displays included a Widgit symbol button (GoTalk), a photographical hotspot (Scene and Heard), and a Widgit symbol button along with a photograph (Scene and Heard). Applications had additional design differences. Two participants showed more rapid and consistent acquisition with the photographical hotspot than with the symbol button format, but did not master the combined format. The third participant mastered all three conditions at comparable rates. Results suggest that AAC display and design elements may influence mand acquisition.
辅助与替代沟通（AAC）应用程序在显示和设计元素的使用上可能存在差异。本研究采用多元素设计，比较了三名患有自闭症谱系障碍的学龄前男性在两款iPad AAC应用程序的三种不同显示方式下对指令获取的情况。显示方式包括一个维吉特符号按钮（GoTalk）、一个摄影热点（Scene and Heard）以及一个带有照片的维吉特符号按钮（Scene and Heard）。应用程序还有其他设计差异。两名参与者对摄影热点的指令获取比符号按钮格式更快且更一致，但未掌握组合格式。第三名参与者以相近的速度掌握了所有三种情况。结果表明，AAC的显示和设计元素可能会影响指令获取。
