Which competence relates to the technical operation of AAC systems?

The correct choice is operational competence, which refers specifically to the skills and knowledge required to effectively use and manage Augmentative and Alternative Communication (AAC) systems. This includes understanding the technical aspects of the devices—such as setting them up, programming, and maintaining them—as well as troubleshooting any issues that may arise during use. Operational competence is crucial for ensuring that individuals can communicate effectively using AAC devices.

In contrast, strategic competence involves the ability to use communication strategies to enhance communication in various situations, while sociolinguistic competence focuses on understanding social rules and cultural norms that influence communication. Psychosocial competence pertains to the emotional and interpersonal skills needed to navigate social interactions. Each of these competencies is important in the realm of communication, but operational competence is specifically aligned with the technical skills necessary for the proper functioning of AAC systems.
