Simple Monotransitive and Complex Dative Alternation Predicates in Spanish Monolingual Child Acquisition Data

This work analyzes the acquisition of simple and complex constructions in Spanish monolingual children’s data. It examines the emergence and the role played by adult input in child production of simple monotransitive constructions when compared to two types of complex predicates that undergo dative alternation (DA), namely, a/para-datives and dative-clitic doubled (DCLD) structures. In order to shed light on these issues, we have analyzed data from Spanish monolingual children and from the adults that they interact with, as available in CHILDES (MacWhinney, Brian. 2000. The CHILDES project: Tools for analyzing talk [Dataset], 3rd edn. Mahwah: Lawrence Erlbaum. http://childes.talkbank.org (accessed 20 October 2019)). The results show that there is an order in the onset of simple and complex predicate constructions, as reflected in the earlier emergence of monotransitives when compared to DA constructions. The latter also show a subsequent order of first occurrence, namely, DCLDs before a/para-datives. Thus, the degree of syntactic complexity seems to have played a role in the acquisition of simple and complex constructions, as measured by the number of Case assignment relations between the verb and its internal argument(s). Moreover, the differences in the Spanish monolingual children’s incidence of the three structures under analysis do not appear to be explained by the relative frequency of exposure in the adult input.
