非言語コミュニケーション
Nonverbal communication is the process of communications by sending and receiving messages without speaking. Intimate relations may be affected by the use of nonverbal communications. Nonverbal communications are transmitted through messaging that utilizes haptic communications (touching, hugs, kisses and caressing someone); body language (physical appearance, posture, gestures and eye contact); oculesics (or eye behavior, including pupil dilation); kinesics (facial expressions and receptive contact from others); and chronemics (time spent with someone else or waiting for someone). All these nonverbal behaviors can affect intimacy or immediacy within a relationship.
