The priest’s sign, which in Polish sign language is shown with the thumb and forefinger of the right hand by “drawing” a collar around the neck, is identical in American and very similar in German, Australian and international – the same gesture is done with both hands.
There are many similar analogies. This allows us to state that sign languages, not only independently of the country, but also of the continent, belong to a family of languages and the similarities existing within this family facilitate the establishment of contact, as in the case, for example , of the Slavic languages. .
Body language is an inseparable element of expression in both auditory and sign language. In it, two types of kinetic behavior can be distinguished: conscious and controlled behavior, manifested, for example, by gestures and facial expressions, and unconscious behavior, such as body position, limb position and some elements of facial expressions.
The non-verbal elements of utterance in sound language include both kinetic and vocal behaviors, in sign language only kinetic behaviors, but much richer than those used in phonic language. These include not only facial and pantomime expressions, but also various intermediate gestures, which do not have a conventional meaning, but which facilitate the perception of the content of the utterance, and sequences of typed signs presenting, for example, proper names using the alphabet of the fingers.
In addition, in the communication cards of deaf people, especially those who do not use a sonorous language, there are also non-verbal elements of an acoustic nature in the form of involuntary sounds, but they usually have no meaning of content, as in speech of people listening sounds like eee, mm, hmm, etc., filling in the gaps in speaking.
