Final answer:
The statement about nonverbal communication cues being referred to as body language is true. Body language includes gestures, vocal qualities, and grooming, which convey powerful messages and emotional information in interpersonal communication.
Step-by-step explanation:
The statement is true: Nonverbal communication cues that send powerful messages through gestures, vocal qualities, manner of dress and grooming are referred to as body language. These cues form an integral part of interpersonal communication and can convey a wide array of information. For instance, gestures like nods or waves can indicate agreement or greeting, while manner of dress and grooming can convey professionalism or social status. Additionally, vocal qualities such as tone, pitch, and volume can express emotions or emphasis beyond the spoken words.
Paralanguage, which includes these vocal qualities along with accent and language, is part of this nonverbal spectrum. Gestures and body movements, or kinesics, while often subconscious, can reveal a person's emotions or attitudes. Smiles and handshakes are nearly universal signs of friendliness and agreement, but the meaning of many other gestures can differ from culture to culture.
Therefore, understanding and correctly interpreting body language—in its broad range of facial expressions, postures, and physical gestures—is crucial for effective communication in both personal and professional contexts.
