Kinesics is the study of body language and non-verbal communication. It includes gestures, facial expressions, posture, and eye contact, all of which convey messages without spoken words. Understanding kinesics can enhance interpersonal communication by providing insights into emotions and intentions. Different cultures may interpret kinesics differently, making it essential to consider context. For example, a thumbs-up gesture may signify approval in some cultures but be offensive in others. By recognizing these variations, individuals can improve their communication skills and foster better relationships in diverse settings.
