Although lexical diversity is often used as a measure of productive proficiency (e.g., as an aspect of lexical complexity) in SLA studies involving oral tasks, relatively little research has been conducted to support the reliability and/or validity of these indices in spoken contexts. Furthermore, SLA researchers commonly use indices of lexical…

Orthography-phonology mapping in world languages exhibits variations. Extensive research has investigated whether orthographic-phonological consistency impacts the cognitive processing of written words. A major body of work has focused on the recognition of phonographic first language (L1) written words. Results show that the more transparent the…

This study investigated three key issues in heritage language (HL) research. Previous research shows HL speakers have an advantage on oral production tasks compared to L2 speakers who instead perform better on written tasks. Furthermore, both L2 and HL speakers are claimed to have a "yes-bias" towards retaining ungrammaticality in GJTs.…

This study builds upon previous research investigating the construct validity of phraseological complexity as an index of L2 development and proficiency. Whereas previous studies have focused on cross-sectional comparisons of written productions across proficiency levels, the current study compares the "longitudinal" development of…

Task modality (oral vs. writing) has been found to affect the production, nature and resolution of the language-related episodes (LREs) produced by adult learners in collaborative interaction, a finding also attested in very recent and still limited research with young learners, a population that deserves greater attention in the literature.…

This study investigated the role of orthographic information in the acquisition of non-native speech sounds by monolingual English listeners. Two potentially important orthographic variables were explored: Orthographic compatibility (whether the orthographic information supports or contradicts the distributional information) and orthographic…

How online interactants advance their talk in written interactions has been extensively investigated in different areas, including language learning. Applying a conversation analysis technique, this study examined how second language (L2) learners managed topics in L2 task-based text-chat interactions and the effects of L2 proficiency on their…

The use of concurrent data elicitation procedures (e.g. think-alouds, eye-tracking, response time) to investigate learners' cognitive processing and processes is becoming more prominent in research designs as researchers seek to acquire a better understanding of how second language (L2) learners process L2 data (e.g. Martin et al., 2019; Rogers,…

This article provides a review of previous studies that have examined the effects of orthography on establishing contrastive phonological representations in second language acquisition and presents results from an original study on Mandarin speakers' production of English stops investigating how the presence of orthography affects the production…

Learning Chinese characters could be challenging for many CSL learners due to the distinction in orthographic features between the Chinese written system and their first languages. While acquisition of orthographic knowledge could be important for learning Chinese characters, how they can gain knowledge about different aspects of Chinese…

Chinese character learning requires various reading subskills, such as radical awareness and character knowledge. Radical awareness refers to learners' ability to identify, analyze, and apply semantic radicals in compound characters. Previous studies have shown that radical awareness and character knowledge facilitate learning semantically…

It is generally agreed that first language (L1) morphological awareness, the ability to reflect upon, analyze and manipulate morphemes and morphological structure of words, can transfer and facilitate second language (L2) reading subskill acquisition. However, the facilitative role of L1 morphological awareness is unclear in the literature…

Concept-based language instruction (C-BLI) is a pedagogy guided by sociocultural theory, which has been shown to be effective in facilitating second language learning. Typical activities include materialization by using a schema for a complete orienting basis of an action (SCOBA) and languaging, through which learners' internalization of…

As second language (L2) research adapts to the dynamics of multimodal instruction, researchers are exploring the role of captioning and textual enhancement (TE) on learner development. The present experiment assesses the differential effects of textually enhanced captions on learners' elicited imitation of L2 Spanish grammar. Twenty-eight…

Judgment tasks (JTs, often called acceptability or grammaticality judgment tasks) are found extensively throughout the history of second language (L2) research. Data from such instruments have been used to investigate a range of hypotheses and phenomena, from generativist theories to instructional effectiveness. Though popular and convenient, JTs…
