Augmentative and alternative communication systems are widely recommended for nonvocal developmentally disabled individuals, with selection-based systems becoming increasingly popular. However, theoretical and experimental evidence suggests that topography-based communication systems are easier to learn. This paper discusses research relevant to the ease of acquisition of topography-based and selection-based systems. Additionally, current practices for choosing and designing communication systems are reviewed in order to investigate the extent to which links have been made with available theoretical and experimental knowledge. A stimulus equivalence model is proposed as a clearer direction for practitioners to follow when planning a communication training program. Suggestions for future research are also offered.
增强性和替代性沟通系统被广泛推荐给非言语发育障碍个体,基于选择的系统越来越受欢迎。然而,理论和实验证据表明,基于形式的沟通系统更容易学习。本文讨论了与基于形式和基于选择的系统的学习难易程度相关的研究。此外,还回顾了当前选择和设计沟通系统的实践,以调查与现有理论和实验知识建立联系的程度。提出了一个刺激等效模型,为从业者在规划沟通训练计划时提供更清晰的指导方向。还提供了对未来研究的建议。
