Gesture

A gesture is a way to share messages without using words. You can use your hands, your face, or other parts of your body to communicate.

These movements can show many feelings, like being happy or being angry. Sometimes, people use gestures while they are speaking to add more meaning to their words. Gestures are different from simple body movements that do not have a specific message. They are a powerful tool for connecting with the people around you.

There are different ways that gestures work. Some are called communicative gestures because they are used on purpose to help speech. For example, a person might point at something to show "this" or "that."

Other moves are called informative gestures. These happen without a specific plan, like scratching an itch or fixing your clothes. These moves might show if a person is uncomfortable, but they are not part of a language.

People have studied gestures for a very long time. A Roman named Marcus Fabius Quintilianus wrote about how to use gestures in speeches. In 1644, an English doctor named John Bulwer wrote a guide about hand gestures called "Chirologia." Later, in 1977, an American psychologist named Andrew N. Meltzoff studied how babies use gestures. He found that newborns only 12 to 21 days old can copy the facial moves of their parents. This shows that we are born with a natural interest in these body moves.

Many different types of manual gestures exist. Symbolic gestures, or emblems, are moves that stand in for words. A wave can mean "hello" or "goodbye" in the United States.

However, a single gesture can mean something very different in another culture. Other moves include deictic gestures, which are used for pointing. There are also motor gestures and lexical gestures that help people communicate. Researchers like Goldin Meadow and Brentari D. found that sign language is just as complex as spoken language.

Gestures are even linked to how our brains work. The parts of the brain used for speech, like Broca's and Wernicke's areas, also handle gestures. Some scholars believe that human language actually started as a system of hand moves. This idea is known as Gestural Theory. It was discussed by the philosopher Abbé de Condillac in the 18th century. Later, in 1973, an anthropologist named Gordon W. Hewes brought this idea back to the discussion. It shows that our hands and our voices have always worked together.
