Zero acquisition : second language acquisition of the parameter of aspect

The goal of this thesis is to present a detailed study of the second language acquisition (SLA) of English aspect by native speakers of Slavic languages. A parameterized distinction between English and Slavic aspect is proposed, in order to account for the subtle differences between English and Slavic telic and alelic sentences. Thus the thesis opens a new area of parameter research in SLA and studies in depth the mental representation of aspect in interlanguage.It is proposed that, the four aspectual classes of verbs (Vendler 1967), viz. accomplishments, achievements, activities and states, can be represented in four different phrase structure templates, projecting from the verb's lexical semantical structure and making reference to the properties of the object. It is argued that the four templates are language universals, and the parameterized distinctions between languages involve the syntactic positions of meaning-based primitive predicates like CAUSE, BECOME and BE (Dowty 1979). It is at this level that the English-Slavic contrast receives an explanation.Based on the syntax-theoretical treatment of Slavic and English aspect, the them investigates the process of SLA of aspect in Slavic speakers at three levels of proficiency in English: low intermediate, high intermediate and advanced. L2 learners are found to be capable of resetting the aspectual parameter value to the English setting, thus successfully acquiring a property of language almost never taught in language classrooms.The thesis also studies the acquisition of a cluster of constructions, which syntactic research relates to the English value of the aspectual parameter, and which have been found to appear together in the speech of English children (Snyder & Stromswold 1997): Double Objects, Verb-Particles and Resultatives. Results indicate that every one of these constructions forms part of this aspect-related cluster and that knowledge of aspect and knowledge of the cluster co-occur.The results of the experimental studies bring new evidence to bear on the theoretical choice between direct access to the L2 value (Epstein, Flynn Martohardjono 1996, Flynn 1996) or starting out the process of acquisition with the L1 value of a parameter (Schwartz & Sprouse 1994, 1996), supporting the latter view
