We must be tuned in to regulating our conversations somehow in order to communicate effectively. We use regulators like eye contact, shifting position to face who's speaking, and head nods. Adaptors help a person adapt to stress or discomfort. People are usually unaware of their adaptors. A person giving a speech might rattle change in their pocket, tap on the podium, or pace about.
Courtship behaviors are full of adaptors.
These include self-grooming behavior, such as adjusting hair or clothing. A behavior that many women practice in these situations, without even realizing it, is rubbing their forearms with their hands. Different cultures will have their own unique gestures. In fact, the same gesture may exist in one or more cultures, but will carry a completely different meaning. Gestures can be used to convey anger, friendliness, or send a warning.
