The Acquisition of Verbs and their Grammar:

language-specific competence within the acquisitional process. Together with the focus on acquisition of the verb and its grammar research in this domain provides a fruitful basis for discussion. The maturation model of language acquisition assumes that UG becomes the language specific grammar over time and that UG is entirely available only up until the time when the native language has been completely acquired (cf. Atkinson 1992, Wexler 1999). Constructivist models that may also be opposed to theories of UG alongside with the usage- based approaches m- tioned above mostly elaborate on the early acquisition of spatial relations (e. g. Bowerman and Choi 2001, Sinha et al. 1999); however, two main hy- theses of this approach – a holistic view of universal spatial cognition and the language specific acquisition hypothesis are beyond the main scope – of this book. The book presents original contributions based on analyses of naturalistic data from eleven languages: Croatian, Dutch, English, Estonian, French, German, Hebrew, Jakarta Indonesian, Japanese, Russian and Spanish. Three of the contributions make cross-linguistic comparisons – between English and Russian; English, German and Spanish; and German, Croatian and English. All papers in the volume investigate first language acquisition and one paper studies both first and second language acquisition.
