The present study examines and compares the extent to which advanced L2 learners of Spanish and Spanish heritage speakers acquire the syntactic and semantic properties that regulate the grammatical representation of double complementizer questions in Spanish, a CP-related structure not present in English. Results from an aural sentence completion…

This article contributes to typological plausibility of Processability Theory (PT) (Pienemann, 1998, 2005) by providing empirical data that show that the stages predicted by PT are followed in the second language (L2) acquisition of Spanish syntax and morphology. In the present article, the PT stages for L2 Spanish morphology and syntax are first…

In three experiments, we examine the effects of semantic context and word concreteness on the mapping of existing meanings to new words. We developed a new-word-learning paradigm in which participants were required to discover the meaning of a new-word form from a specific verbal context. The stimulus materials were manipulated according to word…

This article offers the author's commentary on the Multiple Grammar (MG) language acquisition theory proposed by Luiz Amaral and Tom Roeper in the present issue and touches on other second language acquisition research. Topics discussed include the concept of second language (L2) optionality, a hypothesis regarding the acquisition of the…

In this commentary, the author defends the Multiple Grammars (MG) theory proposed by Luiz Amaral and Tom Roepe (A&R) in the present issue. Topics discussed include second language acquisition, the concept of developmental optionality, and the idea that structural decisions involve the lexical dimension. The author states that A&R's…

The study uses an elicited imitation (EI) task to examine the effect of the native language on the use of the English nongeneric definite article by highly proficient first-language (L1) Spanish and Russian speakers and to test the hierarchy of article difficulty first proposed by Liu and Gleason (2002). Our findings suggest that there is a clear…

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…

This article reports an experiment on the implicit learning of second language stress regularities, and presents a methodological innovation on awareness measurement. After practising two-syllable Spanish words, native Cantonese speakers with English as a second language (L2) completed a judgement task. Critical items differed only in placement of…

A study was conducted to identify the scope and timing of maturational constraints in three linguistic domains within the same individuals, as well as the potential mediating roles of amount of second language (L2) exposure and language aptitude at different ages in different domains. Participants were 65 Chinese learners of Spanish and 12 native…

This study examined whether type of early language experience provides advantages to heritage speakers over second language (L2) learners with morphology, and investigated knowledge of gender agreement and its interaction with diminutive formation. Diminutives are a hallmark of Child Directed Speech in early language development and a highly…

A number of resources provide psycholinguistic researchers with information about the words that the typical child or adult knows in a variety of languages. What is currently not available is a resource that provides information about the words that a typical adult learning a foreign language knows. We created such a resource for Spanish: The…

Mastery of grammatical gender is difficult to achieve in a second language (L2). This study investigates whether persistent difficulty with grammatical gender often observed in the speech of otherwise highly proficient L2 learners is best characterized as a production-specific performance problem, or as difficulty with the retrieval of gender…

This study examined the asymmetrical language switching cost in a word reading task (Experiment 1) and in a categorization task (Experiment 2 and 3). In Experiment 1, Spanish-English bilinguals named words in first language (L1) and second language (L2) in a switching paradigm. They were slower to switch from their weaker L2 to their more dominant…

The present study examines the production outcomes of late second language (L2) learners in order to determine if the mechanisms that allow the creation of phonetic categories remains available during the lifespan, as the Speech Language Model (SLM) claims. In addition, the study focuses on the type of interaction that exists between the first…

Spanish is one of the most widely spoken languages in the world. Quechua is the largest indigenous language family to constitute the first language (L1) of second language (L2) Spanish speakers. Despite sheer number of speakers and typologically interesting contrasts, Quechua-Spanish second language acquisition is a nearly untapped research area,…
