“…This emerging understanding may then support children’s engagement and understanding of various types of joint activities. Previous research investigating how young children establish and sustain sociodramatic play with peers, for example, has shown that from the age of 3 onward, children begin to negotiate the content of their envisaged game before starting to play, and later even step out of the actual play activity in order to redirect each others’ actions and to re-establish the arranged game (e.g., Baker-Senett, Matusov, & Rogoff, 1992; Lloyd & Goodwin, 1995; Verba, 1993). After their third birthday, children also begin to use verbal polite forms when conversing with others, suggesting that they have acquired some rudimentary understanding of how partners ought to address each other in particular communicative contexts (Bates & Silvern, 1977; Nippold, Leonard, & Anastopoulos, 1982; Snow, Perlmann, Gleason, & Hooshyar, 1990).…”
