'Explains the function of the gesture in public speaking and points out how speeches can be made much more effective by using the correct gestures at the correct time. Gives some specific examples of some commonly used gestures and their function.'

Originally a public domain film from the Library of Congress Prelinger Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.

The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

A gesture is a form of non-verbal communication or non-vocal communication in which visible bodily actions communicate particular messages, either in place of, or in conjunction with, speech. Gestures include movement of the hands, face, or other parts of the body. Gestures differ from physical non-verbal communication that does not communicate specific messages, such as purely expressive displays, proxemics, or displays of joint attention. Gestures allow individuals to communicate a variety of feelings and thoughts, from contempt and hostility to approval and affection, often together with body language in addition to words when they speak. Gesticulation and speech work independently of each other, but join to provide emphasis and meaning.

Gesture processing takes place in areas of the brain such as Broca's and Wernicke's areas, which are used by speech and sign language. In fact, language is thought by some scholars to have evolved in Homo sapiens from an earlier system consisting of manual gestures. The theory that language evolved from manual gestures, termed Gestural Theory, dates back to the work of 18th-century philosopher and priest Abbé de Condillac, and has been revived by contemporary anthropologist Gordon W. Hewes, in 1973, as part of a discussion on the origin of language...

Communicative (Active Gestures)

Communicative gestures are gestures that are produced intentionally and meaningfully by a person as a way of intensifying or modifying speech produced in the vocal tract (or with the hands in the case of sign languages), even though a speaker may not be actively aware that they are producing communicative gestures. For instance, on the picture above of Uncle Sam, he is pointing and sending a non-verbal form of gesture by implying he wants you to join the U.S. Army. This is a form of symbolic gesture, usually used in the absence of speech...
