Turn regulation consists of taking, maintaining and giving turn in a conversational setting. It has been shown, that the sign palm_up (see Figure a.), which does not have a lexical meaning, can be used in all these three interactional functions, but is mostly used for filling pauses, i.e. for turn keeping. Another manual marker of turn keeping is the wiggling of the fingers while thinking (shown in Figure b.).
