What is defined as the use of verbal or nonverbal communication methods such as speech, sign, or gestures?

The correct answer is expressive language, which refers to the use of various forms of communication to convey thoughts, feelings, and ideas. This encompasses both verbal communication, such as speaking and writing, and nonverbal communication methods like sign language, gestures, and body language. Expressive language is essential in music therapy, as it allows clients to express themselves creatively and interact with their therapist and peers.

In contrast, receptive language involves the ability to understand and process the communication of others, rather than actively producing it. Augmentative language pertains to methods that support or enhance communication, particularly for individuals with speech or language impairments. Functional communication refers to practical expressions that facilitate everyday interactions and activities. While these concepts are interconnected, expressive language specifically highlights the active aspect of communication where an individual expresses themselves.
