AAC communication in autism is a valuable tool for individuals who have difficulty with speech or verbal communication. However, AAC communication in autism also presents unique challenges, especially when it comes to understanding and following social rules and maintaining conversational boundaries. Augmentative and alternative communication (AAC) systems offer a way for users to express themselves, but they still need support to navigate social norms, such as knowing when and how to initiate, participate, and exit conversations appropriately.
Strategies for Navigating Social Rules and Conversational Boundaries
Here are some strategies to help AAC users navigate social rules and conversational boundaries:
Use Visual Supports and Social Stories
Augmentative communication tools, such as visual symbols or social stories, can help AAC users understand key social rules. These stories can provide examples of how to start and end conversations, wait for turns to speak, and recognize when others are ready to engage. Social stories can illustrate scenarios where a user might need to pause, give space, or ask a follow-up question.
Provide Structured Conversation
Practice Conversation support through role-playing and structured practice is another effective way to teach AAC users how to manage conversational boundaries. Practising different conversation scenarios with prompts can help users understand how to communicate effectively, such as when to ask a question, make a comment, or signal that they want to exit a conversation.
Model Social Rules and Boundaries
Teachers and carers can model appropriate social rules in real-time conversations, showing how to respect conversational boundaries and make appropriate responses.
