One of the most common ways touch is used to communicate is through the handshake. At its most basic level, the handshake communicates trust, goodwill, or agreement with a common decision.

A handshake that uses two hands or extends to the elbow can convey care or condolence. But we also use tons of other "touching" signals - a pat on the back to show support, or a stroke of the arm to show sexual interest.
