“…Spontaneous speech as well as experimental production data from German-and Japanese-speaking children suggest that the acquisition of both kinds of particles is achieved early. Previous research has provided evidence that from the beginning of multiword utterances German-speaking children use the additive particle auch to encode aspects of information structure (Dimroth, 2009;Höhle, Berger, Mü ller, Schmitz & Weissenborn, 2009 ;Nederstigt, 2003 ;Penner, Tracy & Weissenborn, 2000). For Japanese-speaking children the use of the additive particle mo ' also ' and the restrictive particle dake 'only ' has been observed in the productions of children from age 1 ;6-2 ;3 and from age 2 ; 1-2 ; 7 respectively, with a slight temporal delay for the restrictive particle (Matsuoka, Miyoshi, Hoshi, Ueda, Yabu & Hirata, 2006).…”
