Research employing psycholinguistic techniques to assess the on-line processing of collocation by native and non-native speakers has flourished in the past few years. This line of research aims (among other things) at exploring actual performance in real time as opposed to the traditional paper-and-pencil testing techniques that have been…

We investigate whether second language (L2) learners of English rely on first language (L1) transfer and atomicity in the acquisition of the count/mass distinction by examining L1-French and L1-Chinese learners of English. Atomicity encodes whether a noun contains 'atoms' or minimal elements that retain the property of the noun. As a semantic…

Norwegian allows filler-gap dependencies into embedded questions, which are islands for filler-gap dependency formation in English. We ask whether there is evidence that Norwegian learners of English transfer the functional structure that permits island violations from their first language (L1) to their second language (L2). In two acceptability…

Semantic variables enable L2 researchers and materials creators to quantify and control the effects of meaning on cognition. However, in recent years, many variables have been normed and published. Parsing the methods employed in norming this myriad of variables and which disparate theories informed their creation can be an opaque and arduous…

This article offers a methodological synthesis spanning 35 years of instructed second language acquisition research on the efficacy of form-focused instruction. Eighty-eight (quasi-) experimental studies were sampled from six academic journals: "Applied Linguistics," "Language Learning," "Language Teaching Research,"…

This paper examines evidence for relationships among individual differences (IDs) in L1 achievement, L2 aptitude, and L2 achievement. It begins by providing an overview of my academic journey from L1 educator to L2 researcher and explains the development of the Linguistic Coding Differences Hypothesis (LCDH). Next, I review Peter Skehan's…

While language aptitude and motivation are considered to be important contributors to second language (L2) attainment, two major gaps in the past research have been (1) a lack of nonlinear models stemming from a naive and tacit assumption that learning outcomes are linearly related to their predictors, and (2) a lack of unified and integrative…

In the L2 fluency literature there is considerable debate over how best to operationally define pauses and how different pause measures relate to L2 proficiency. This creates a challenge for researchers interested in L2 fluency, and particularly those who are working with groups that vary in L2 proficiency. This article addresses these issues by…

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…

This dissertation presents three studies that examined issues related to the production and the perception of pitch in a tone language. The first study examined linguistic contexts that may modulate consonant-induced pitch perturbations (CF0) in a tone language. Previous studies have produced mixed findings regarding the role of linguistic…

When reading in a second language, a reader's first language may be involved. For word reading, the question is how and at what level: lexical, pre-lexical, or both. In three experiments, we employed an implicit reading task (color judgment) and an explicit reading task (word naming) to test whether a Chinese meaning equivalent character and its…

Previous studies in the acquisition of clitic se in Spanish have focused on the syntactic processes needed to perform detransitivization. However, current approaches on event structure reveal that "se" encodes aspectual information which is crucial for its acquisition. We examine the use, intuition and interpretation of the aspectual…

Whilst the links between learner corpus research (LCR) and Second Language Acquisition (SLA) have long been debated, McEnery et al. (2019. "Corpus Linguistics, Learner Corpora, and SLA: Employing Technology to Analyze Language Use." Annual Review of Applied Linguistics 39: 74-92. doi:10.1017/S0267190519000096) claim that learner corpus…

This study investigated second language distribution of Chinese connectives by tallying responses on a mini-discourse completion test taken by English-speaking learners with different language learning backgrounds and at different proficiency levels. The results showed that an underuse pattern underlay practically all Chinese connectives as a…

Many people speak more than two languages. How do languages acquired earlier affect the learnability of additional languages? We show that linguistic distances between speakers' first (L1) and second (L2) languages and their third (L3) language play a role. Larger distances from the L1 to the L3 and from the L2 to the L3 correlate with lower…
