How do affect displays function in kinesics?

Affect displays in kinesics are important non-verbal cues that communicate emotions and feelings through facial expressions, gestures, posture, and other body movements. By revealing emotional states, they provide insight into how someone is feeling at a given moment, which can significantly enhance interpersonal communication. For example, a smile can express happiness, while crossed arms may indicate defensiveness or discomfort.

Understanding affect displays can strengthen communication by allowing individuals to respond appropriately to the emotional context of a situation. This means that when we interpret these non-verbal signals correctly, we can better empathize with others and create more meaningful exchanges. Therefore, option B directly aligns with the fundamental role of affect displays in kinesics, emphasizing their function as indicators of emotional states rather than merely enforcing norms, regulating conversation flow, or providing information.
