Greek and Spanish are two languages that display a similar subject distribution with unergative/unaccusative verbs, but different word orders with focused subjects (SV in Greek and VS in Spanish). Here we consider subject-verb word order in second language (L2) Greek and L2 Spanish in order to test the Interface Hypothesis (IH). To this end, we…

The present study explored the processing units of high-proficiency second language (L2) Chinese learners in on-line reading in an eye-tracking experiment. The critical aim was to investigate how learners segment continuous characters into words without the aid of word boundary demarcations. Based on previous studies, the embedded words of 2- and…

Relative clauses have long been examined in research on first (L1) and second (L2) language acquisition and processing, and a large body of research has shown that object relative clauses (e.g. 'The boy that the girl saw') are more difficult to process than subject relative clauses (e.g. 'The boy that saw the girl'). Although there are different…

As Chinese shows both satellite- and verb-framed properties (Slobin, 2004; Talmy, 2012, 2016), it provides a unique lens through which to observe the extent of first-language (L1) typological influence in second language (L2) acquisition of motion expressions. This study has dual purposes. First, it extends Wu's (2016) investigation on motion…

Heritage speakers (HS) have been shown to experience difficulties with inflectional morphology (particularly with irregular morphology) and to frequently overapply regular morphology. The present study seeks to get further insight into the inflectional processes of HS by investigating how these are generalized to nonce words in language…

This study examines whether second language (L2) learners predict upcoming language prior to the verb in Japanese. Taking the dependency involving negative polarity adverbs -- "zenzen" 'at all' and "amari" '(not) very' -- as a test case, this study examined whether Japanese native speakers and L2 learners of Japanese, aided by…

Event concepts of common verbs (e.g. "eat," "sleep") can be broadly shared across languages, but a given language's rules for subcategorization are largely arbitrary and vary substantially across languages. When subcategorization information does not match between first language (L1) and second language (L2), how does this…

This article provides a Poverty of Stimulus argument for the participation of a dedicated linguistic module in second language acquisition. We study the second language (L2) acquisition of a subset of English infinitive complements that exhibit the following properties: (a) they present an intricate web of grammatical constraints while (b) they…

The present study examines the production and intuition of Spanish clitics in clitic left dislocation (CLLD) structures among 26 Spanish heritage speakers (HSs) born and raised in Brazil. We tested clitic production and intuition in contexts in which Spanish clitics vary as a function of the semantic features of the object that they refer to.…

The present investigation examines intra-speaker variability in heritage speakers (HSs) of Spanish by focusing on the potential effects of two variables in their acquisition of mood: lexical frequency and morphological regularity. To do so, this study tested participants' interpretation and use of early-acquired mood alternations conveying either…

The Interface Hypothesis proposes that second language (L2) learners, even at highly proficient levels, often fail to integrate information at the external interfaces where grammar interacts with other cognitive systems. While much early L2 work has focused on the syntax-discourse interface or scalar implicatures at the semantics-pragmatics…

This study tests the Competing Systems Hypothesis (CSH) as applied to adult second language acquisition of aspect in Spanish. The CSH purports that differences among tutored and untutored learners result from competition between one system of underlying grammatical knowledge and another of learned metalinguistic knowledge in tutored learners…

Expression of motion shows systematic inter-typological variability between language types, particularly with respect to manner and path components of motion: speakers of satellite-framed languages (S-language; e.g. German) frequently conflate manner and path into a single clause, while verb-framed language speakers (V-language; e.g. Spanish)…

Grammar competition has been proposed as a model for second language (L2) acquisition. Variational Learning provides a framework within which to investigate the idea of grammar competition as the model requires a marriage of quantitative properties of the input with Universal Grammar. A diachronic variational model of grammar competition is…

How strongly a verb is associated with a construction plays a crucial role in the learning of argument structure constructions. We examined the effect of verb-construction association strength on second language (L2) constructional generalization by analysing L2 learners' production and comprehension of two complex constructions (i.e. ditransitive…
