This commentary discusses Westergaard's (2021) keynote article, which presents a comprehensive model of first language (L1), second language (L2), and third language (L3) acquisition. The commentary presents evidence from a previous study of L3 learners that provides support for Westergaard's property-by-property transfer proposal. The commentary…

The present study examines both properties of the language and properties of the learner to better understand variability at the earliest stages of second language (L2) acquisition. We used event-related potentials, an oral production task, and a battery of individual differences measures to examine the processing of number and gender agreement in…

This study investigates L2 learners' ability to use morphosyntactic gender as a predictive cue during the processing of Hindi agreement dependencies. Nine L2 learners of low-intermediate proficiency and nine highly proficient multilingual speakers who consider Hindi one of their dominant languages were tested using a speeded picture-selection…

Different theoretical accounts of second language (L2) acquisition differ with respect to whether or not advanced learners are predicted to show native-like processing for features not instantiated in the native language (L1). We examined how native speakers of English, a language with number but not gender agreement, process number and gender…

Previous studies on the second language acquisition of telicity have suggested that learners can use morphosyntactic cues to interpret sentences as telic or atelic even in cases where the cues differ in the first language (L1) and second language (L2) (Slabakova, 2001, 2005; Gabriele, 2008; Kaku et al., 2008a, 2008b). The present study extends…

The study examines emergent literacy skills in a group of young English Language Learners who are dominant in their native language, Spanish. We investigate the relative contribution of syntactic comprehension in the L1 and L2 to the development of emergent reading skills in English. Participants were bilingual kindergarteners from two public…
