Different from precognition and intuition, the practice of communicating mind-to-mind is an example of extrasensory perception. Renee Sarouphim and her husband play a "telepathy" game with their children each night. "In this game," she said, "my husband and I take turns and try to think about something and the children try to 'guess' or 'read' what it is that we're about. It can be an object, a person, an event, anything." The game, Sarouphim said, will help her children concentrate and bring the family closer together. "It helps us communicate and understand each other without the use of words," Sarouphim said, "and the children find it extremely funny, actually." So what exactly is telepathy? Derived from the Greek term "tele," meaning "distant," and "pathe," meaning "feeling," telepathy, said Sociologist Ghada Khoury, is a direct transference of thought from one person to another. The former, she said, is usually referred to as "sender" or "agent" and the latter is referred to as "receiver" or "percipient." "Telepathy is done without using any of the five physical senses," Khoury said. "It's a form of extrasensory perception (ESP)." The existence of telepathy has not yet been proved, said anthropologist Elias Deeb, "yet some research studies have produced favorable results using such techniques as card guessing with a special deck of five sets of five cards," he said.
