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…

Two experiments involving picture classifications investigated priming behavior in the context of "wh"-movement at clause edge and in indirect object position, respectively. In Experiment 1, intermediate L1-Chinese L2-English learners produced slower classification times (inhibitions) at clause edge, apparently induced by the computation of…

This article examined the integration of semantic and morphosyntactic information by Korean learners of English as a second language (L2). In Experiment 1, L2 learners listened to English active or passive sentences that were either plausible or implausible and translated them into Korean. A significant number of Korean translations maintained the…

This article reports empirical findings from an ongoing investigation into the acquisition of second-language (L2) phonemic contrasts. Specifically, we consider the status and role of the phenomenon of hypercorrection in the various stages through which L2 learners develop and internalize a target language (TL) contrast. We adopt the prevailing…

Second language (L2) learners have been found to experience difficulty in tasks that require the integration of discourse-pragmatic properties with syntactic and semantic properties (Sorace and Serratrice, 2009; Tsimpli and Sorace, 2006; Valenzuela, 2006). The present article investigates the sources of L2 difficulty in a phenomenon where multiple…

In order to identify the causes of inflectional variability in adult second-language (L2) acquisition, this study investigates lexical and syntactic aspects of gender processing in real-time L2 production and comprehension. Twenty advanced to near-native adult first language (L1) English speakers of L2 German and 20 native controls were tested in…

This study examined the second language (L2) acquisition of the Korean plural marker -"tul" by native speakers of English. Seventy-seven learners at four Korean proficiency levels along with 31 native Korean-speaking controls completed five tasks designed to probe for knowledge of particular features and restrictions associated with so-called…

We report findings from psycholinguistic experiments investigating the detailed timing of processing morphologically complex words by proficient adult second (L2) language learners of English in comparison to adult native (L1) speakers of English. The first study employed the masked priming technique to investigate "-ed" forms with a group of…

The central goal of the field of second language acquisition (SLA) is to describe and explain how second language learners acquire the target language. In order to achieve this goal, SLA researchers work with second language data, which can take a variety of forms, including (but not limited to) such commonly used methods as naturalistic…

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…

The present study is an attempt to empirically test and compare the results of three methods of word association (WA) analysis. Two of the methods--namely, associative commonality and nativelikeness, and lexico-syntactic patterns of associative organization--have been traditionally used in both first language (L1) and second language (L2)…

It is well known that adult US-English-speaking learners of French experience difficulties acquiring high /y/-/u/ and mid /oe/-/[openo]/ front vs. back rounded vowel contrasts in French. This study examines the acquisition of these French vowel contrasts at two levels: phonetic categorization and lexical representations. An ABX categorization task…

In this article, a survey of current psycholinguistic techniques relevant to second language acquisition (SLA) research is presented. I summarize many of the available methods and discuss their use with particular reference to two critical questions in current SLA research: (1) What does a learner's current knowledge of the second language (L2)…

This article investigates how adult Korean-speaking learners of English interpret English definite descriptions ("the book," "the books") and demonstrative descriptions ("that book," "those books"). Korean lacks articles, but has demonstratives, and it is hypothesized that transfer leads learners to (initially) equate definites with…
