Which function is NOT classified under communicative functions?

The correct answer is based on the understanding of what constitutes communicative functions in the context of communication disorders. Communicative functions refer to the purposes for which we use language and communication in our interactions with others.

Behavior regulation, social interaction, and joint attention are all recognized as key elements of communicative functions.

1. Behavior regulation involves using communication to influence the behavior of others, such as requesting, protesting, or directing actions.

2. Social interaction encompasses the use of language and other forms of communication to build relationships, share experiences, and engage with others socially.

3. Joint attention refers to the capacity to share focus on an object or event with another person, which is fundamental for developing social skills and language through mutual engagement.

In contrast, motor skills development is not classified under communicative functions. While motor skills—like speaking, gesturing, or using tools—can support communication, the development of motor skills itself does not have a communicative intent or purpose in the same way that the other options do. Therefore, it stands out as the function that does not fall within the category of communicative functions.
