Good listening skills involve the observation of which aspect?

Good listening skills indeed involve the observation of body language. This aspect is critical because non-verbal cues often provide context and deeper understanding of what is being communicated. For example, a person's posture, facial expressions, and gestures can indicate their feelings, comfort level, and engagement in the conversation. Recognizing these signals allows a listener to respond more effectively and empathetically.

While tone of voice is also important—as it can convey emotions and emphasize certain points—body language encompasses a broader range of communication signals that complement and enhance verbal exchanges. Written words, on the other hand, do not apply to the act of listening in a traditional dialogue, as listening is predominantly oral and interpersonal. Silence can indicate various things such as thoughtfulness or discomfort, but without body language, it lacks the comprehensive context needed for effective listening. Thus, observing body language enriches the listening process by providing critical insights into the speaker's state of mind.
