Kinesics refers to the study of body movements and gestures used for nonverbal communication. It includes factors like personal appearance, posture, eye contact, facial expressions, use of time (chronemics), and paralinguistics. Good posture conveys confidence while bad posture shows lack of interest or confidence. Eye contact regulates conversations and shows engagement or intimidation. Facial expressions effectively communicate emotions like happiness, sadness, fear, and anger through movements of the eyes, eyebrows, jaw, and mouth. Paralinguistics refers to nonverbal vocal cues like volume and pitch that add emphasis. Together, these nonverbal cues convey much about personalities, feelings, and the message being communicated.
