Therapists and educators frequently teach alternative-communication systems, such as picture exchanges or manual signs, to individuals with developmental disabilities who present with expressive language deficits. Michael (1985) recommended a taxonomy for alternative communication systems that differentiated between selection-based systems in which each response is topographically identical (e.g., card selection and exchange systems) and topography-based systems in which each response is topographically distinct (e.g., signed language). We compared the efficiency of training picture exchanges and signs with 3 participants who presented with severe language deficits; all participants acquired the picture-exchange responses more readily.
治疗师和教育工作者经常向有表达性语言缺陷的发育障碍个体教授替代性沟通系统，如画片交流或手势语。迈克尔（1985年）推荐了一种替代性沟通系统的分类法，该分类法区分了基于选择的系统（其中每个反应在形式上是相同的，例如卡片选择和交换系统）和基于形式的系统（其中每个反应在形式上是不同的，例如手语）。我们比较了对3名有严重语言缺陷的参与者进行画片交流和手势语训练的效率；所有参与者都更容易学会画片交流反应。
