Which nonverbal is LEAST likely to present a barrier to communication?

• A. Frowning
• B. Staring
• C. Slouching
• D. Nodding

Answer: (D)

Nodding shows you are listening and understanding, which helps the other person feel heard and encourages them to share more. In any interaction, especially in healthcare, this positive nonverbal cue reduces barriers by confirming you’re following along and not judging, making communication flow more smoothly.

Frowning conveys disapproval or confusion, which can make the speaker hesitant or anxious to continue. Staring can feel aggressive or invasive, signaling distrust or pressure. Slouching projects disinterest or fatigue, signaling that you’re not engaged. Together, these nonverbal signals can create distance and hinder open dialogue, so they’re more likely to disrupt communication than to support it.
