What is a key difference between verbal and nonverbal communication?

The key difference highlighted in the correct choice emphasizes that verbal communication relies on spoken or written words, whereas nonverbal communication does not utilize words in the same way. Verbal communication is typically characterized by the use of language to convey messages, which can be spoken or written, allowing for structured expression of thoughts and ideas. In contrast, nonverbal communication encompasses a wide range of other forms of expression, including body language, facial expressions, gestures, posture, and even tone of voice, all of which can convey meaning without the need for verbalization. This distinction is fundamental in understanding how different forms of communication can affect interpersonal interactions and the nuances involved in conveying emotions and intentions.

The other options misrepresent the characteristics of verbal and nonverbal communication or make claims that are not universally supported by evidence, such as suggesting that nonverbal communication is always preferred in cognitive tasks, which may not hold true in all situations.
