Final answer:
It is true that as communicator motivation increases, so does communicative competence, due to a greater investment in learning and practicing language skills.
Step-by-step explanation:
The statement "As communicator motivation increases, communicative competence increases" is generally considered to be true. Communicative competence involves knowing how to speak appropriately in different social contexts and being able to understand and produce language effectively. Increased motivation in a communicator often leads to a greater investment in learning and practicing communication skills, thus enhancing communicative competence. Examples can be seen in language learning, where motivated students tend to achieve higher levels of fluency and understanding of the cultural context within which the language is spoken.
