GISELA HA Ê KANSSON
Lund UniversityThis paper compares the development of tense morphology and verb-second in different learner populations. Three groups of Swedish pre-school children are investigated longitudinally; ten L1 children, ten L2 children and ten children diagnosed with Speci®c Language Impairment (SLI). Data was collected twice, with an interval of six months. The results at Time I reveal a signi®cant difference between normally developing L1 children on the one hand and L2 children and children with SLI on the other. The L1 children use verb-second correctly in topicalized declaratives, whereas both L2 children and children with SLI use structures with the verb in third position (XSV structures) as an intermediate step towards verb-second. There is a clear development between the two data collection sessions for the L2 children and the children with SLI, diminishing the difference between them and the unimpaired L1 children. The similarity that is found between L2 children and children with SLI in this study bears important implications for the discussion of the role of transfer in L2 research and for the question of a defective linguistic representation in SLI research.The acquisition of verb-second in L1 and L2 acquisition has been a matter of debate in the literature on language acquisition for some time. Especially within the UG framework this has been a hot topic, as is witnessed by the large number of journal articles and book volumes that have been devoted to this subject. It has been suggested, and is generally assumed, that this is a case where syntax and morphology interlock, i.e. only ®nite verbs raise to the verb-second position. Interestingly enough, there seems to be a difference between L1 learners and L2 learners in this respect. For example, the acquisition of subject±verb agreement has been found to coincide with the acquisition of verb-second in L1 children but not in L2 acquisition (e.g. Clahsen and Muysken, 1989). Most research has dealt with German (Clahsen and Muysken, 1986, 1989;Eubank, 1992; Meisel and Mu Èller, 1992;Meisel, 1994) but there are also studies on Swedish (Platzack, 1992(Platzack, , 1996. Si...
