“…Question acquisition in young children has been an important topic of continued investigation since Davis’s (1932) analyses of the development of interrogative forms and functions in early childhood English. In the past century, a considerable amount of research has been conducted to explore (1) developmental trends in interrogative forms (Berninger & Garvey, 1981; Erreich, 1984; Ervin-Tripp, 1970; Klima & Bellugi, 1966; Olsen-Fulero & Conforti, 1983; Piaget, 1926; Shatz, 1978; Tyack & Ingram, 1977); (2) the pragmatic functions of interrogatives directed at children (Loukusa, Leinonen, & Ryder, 2007; Shatz, 1979) and generated by children themselves (James & Seebach, 1982; Sachs & Devin, 1976); and (3) the development of interrogative forms and functions in first language (L1) acquisition (Clancy, 1989; Davis, 1932; James & Seebach, 1982; Meyer & Shrine, 1973; Vaidyanathan, 1988) and second language acquisition (L2) (Jackson & Bobb, 2009; Myles, Mitchell, & Hooper, 1999; Spada & Lightbown, 1993). These studies tend to conclude that children have acquired all the interrogative forms and functions of English and other European languages prior to starting school.…”
