The Acquisition of Aspect in L2 Portuguese & Spanish: Exploring Native/Non-Native Performance Differences.

This study investigates the possibility of native-like ultimate attainment by analyzing L2 knowledge of aspect as seen in the Preterit/Imperfect contrast of highly successful English L2 learners of Portuguese and Spanish. Building on innovative work by Montrul & Slabakova (2003) and Slabakova & Montrul (2003), we test knowledge of semantic entailments associated with the acquisition of [+/- perfective] features checked in higher AspP. Additionally, we investigate the possibility of a specific pattern of associated target-deviant L2 performance. We hypothesize that L2 performance can be affected by explicit positive evidence (pedagogical rules) despite otherwise demonstrable native-like competence. Indeed, the data reveal a pattern of target-deviant performance noted only in three specific contexts, all of which can be linked to traditional instruction: (a) with particular stative verbs not used in the Preterit (b) when preceded by certain adverbial phrases (e.g.,siempre) and (c) so-called semantic shifting verbs (e.g., sabía vs. supe).

Acquisition of inflected and uninflected infinitives in child L1 European Portuguese

This study investigates the child (L1) acquisition of inflected and uninflected infinitives in European Portuguese (EP). We test and contrast properties involving two interfaces, focusing on morpho-syntactic and syntax-semantics properties of inflected infinitives, in contrast with uninflected infinitives. We present experimental results from three monolingual EP child groups, between ages 6 and 12 (n=72), compared to EP adults (n=32). Results show that children as young as 6-7 have knowledge of the morpho-syntactic properties of inflected infinitives, although at first glance they show insufficient knowledge of their syntax-semantics interface properties (i.e. non-obligatory control properties), differently from older children, who show evidence of knowledge of both types of properties. We argue that, in general, morpho-syntactic and syntax-semantics interface distinctions are also accessible to 6-7 children, but children may not show the entire range of interpretations possible for adults.
